Decision-making for the selection of treatment alternatives and landfilling of municipal solid waste (MSW) is based on the experience and judgment of those management responsible, without considering multicriteria analysis. Therefore, the purpose of this research was to determine the treatment scenario and landfilling of MSW with the lowest environmental and economic costs in a medium-sized city. The methodology included the definition and data processing of the project (population, generation, and composition of MSW), for 16 years. In the design of scenarios, recycling, composting, incineration with energy recovery, and landfilling treatments were proposed; later, the combinations of treatments for each type of residue were generated. The results showed 36 scenarios, then the ELECTRE method was applied to the five with the lowest economical and environmental costs. Finally from the latter, one dominant scenario was determined: organic waste in composting; plastic, paper, and glass in recycling; and ‘others’ in landfilling. It is concluded that the final decision on the scenario is adapted to the particular conditions of the locality. Full article

In the literature, a lot is discussed about how agroforestry can achieve the mitigation, adaptation and productivity goals of climate-smart agriculture (CSA). However, this may be relatively too broad to assess the trade-offs and synergies of how specific agroforestry technologies or practices achieve the three pillars of CSA. Here, we provide an overview of how improved fallows (an agroforestry technology consisting of planting mainly legume tree/shrub species in rotation with cultivated crops) may achieve the goals of climate-smart agriculture in Sub-Saharan Africa (SSA). Our review showed that improved fallow systems have real potential to contribute to food security and climate change mitigation and adaptation in SSA. Under proper management, improved fallows can increase maize yields to about 6 t ha−1, which is comparable to conventional maize yields under fertilization. This is attributed to improved soil fertility and nutrient use efficiency. Although data was generally limited, the growing literature showed that improved fallows increased soil carbon sequestration and reduced greenhouse emissions. Further, as a multiple output land use system, improved fallows may increase fodder availability during dry periods and provide substantial biomass for charcoal production. These livelihood options may become important financial safety nets during off seasons or in the event of crop failures. This notwithstanding, the adoption of improved fallows is mainly in Southern and Eastern Africa, where over 20,000 farmers are now using Sesbania sesban, Tephrosia vogelii, and Cajanus cajan in two-year fallows followed by maize rotations. Land tenure issues, lack of social capital, and improved germplasm and accessions of fallow species have been cited as constraints to scaling up. However, development of seed orchards, nursery development, and the willingness of policy makers to create a policy environment that addresses market failures and alleviates disincentives should improve adoption and future scaling up.

Agricultural producers grapple with low farm yields and declining ecosystem services within their landscapes. In several instances, agricultural production systems may be considered largely unsustainable in socioeconomic and ecological (resource conservation and use and impact on nature) terms. Novel technological and management options that can serve as vehicles to promote the provision of multiple benefits, including the improvement of smallholder livelihoods, are needed. We call for a paradigm shift to allow designing and implementing agricultural systems that are not only efficient (serving as a means to promote development based on the concept of creating more goods and services while using fewer resources and creating less waste) but can also be considered synergistic (symbiotic relationship between socio-ecological systems) by simultaneously contributing to major objectives of economic, ecological, and social (equity) improvement of agro-ecosystems. These transformations require strategic approaches that are supported by participatory system-level research, experimentation, and innovation. Using data from several studies, we here provide evidence for technological and management options that could be optimized, promoted, and adopted to enable agricultural systems to be efficient, effective, and, indeed, sustainable. Specifically, we present results from a study conducted in Colombia, which demonstrated that, in rice systems, improved water management practices such as Alternate Wetting and Drying (AWD) reduce methane emissions (~70%). We also show how women can play a key role in AWD adoption. For livestock systems, we present in vitro evidence showing that the use of alternative feed options such as cassava leaves contributes to livestock feed supplementation and could represent a cost-effective approach for reducing enteric methane emissions (22% to 55%). We argue that to design and benefit from sustainable agricultural systems, there is a need for better targeting of interventions that are co-designed, co-evaluated, and co-promoted, with farmers as allies of transformational change (as done in the climate-smart villages), not as recipients of external knowledge. Moreover, for inclusive sustainability that harnesses existing knowledge and influences decision-making processes across scales, there is a need for constant, efficient, effective, and real trans-disciplinary communication and collaboration.

A translog production function model with input factors including energy, capital, and labor is established for China’s heavy industry. Using the ridge regression method, the output elasticity of each input factor and the substitution elasticity between input factors are analyzed. The empirical results show that the output elasticity of energy, capital and labor are all positive, while the output elasticities of energy and capital are relatively higher, indicating that China’s heavy industry is energy- and capital-intensive. Simultaneously, all the input factors are substitutes, with the substitution between labor and energy having the highest degree of responsiveness. The substitution elasticity between labor and energy is decreasing, while the substitution elasticities of capital for energy and labor are increasing. More capital input can help to improve energy efficiency and thus accomplish the goal of energy conservation in China’s heavy industry. Full article

Agriculture in South Asia is largely dependent on rainfall, where about two-thirds of the cultivable lands lack irrigation facilities. In recent years, increasing frequency and severity of droughts have had a severe impact on rainfed agriculture and livelihood of millions of farmers in the region. There are numerous drought adaptation and mitigation options available for rainfed agriculture. A seed bank is one of those options that can play an important role in minimizing the effect of droughts on crop production. This paper assesses the need for seed banks in rainfed/partially irrigated areas of South Asia for the purpose of drought risk management. The need for additional seeds of the main crops or suitable alternative crops for re-sowing/planting after drought-induced losses of the main crop was assessed by using long-term gridded rainfall data and crop information. Results show that very limited rainfed areas in South Asia require additional seeds of main or alternative crops for drought risk management once in five to seven years’ drought return period. About 90 percent of such areas in South Asia may require additional seeds for drought risk management once in 10 years or more. The timing and severity of droughts during cropping season and cost/benefits of seed bank maintenance play a major role in choosing additional seeds for the main crops and/or alternate crops for maintenance in the large seed banks. This study shows that, despite the large investment requirement, maintenance of large seed banks for drought risks management is economically viable for the limited areas in South Asia. Full article

As mining companies reveal more and more public information about themselves, the behaviour fosters a better image. This article aims to present two industry leaders in the context of environmental requirements they have met (status at the end of 2015), acting in compliance with the general principles of a socially responsible business. The choice of KGHM (Kombinat Gorniczo-Hutniczy Miedzi) companies (copper ores and other accompanying elements) CG PGE (Capital Group Polska Grupa Energetyczna S.A.) (lignite) was dictated by their significant share in the mining industry in Poland. The environmental aspects of the integrated monthly reports were listed and grouped in detail in accordance with the applicable Global Reporting Initiative (GRI) and GRI G4 Mining and Metals guidelines. The values of environmental indicators have been analysed over the years, including inter alia data concerning gas emissions, that is, CO2, SOx, NOx, PM or generated waste and sewage. Also, with regard to the environmental aspect of the work, energy consumption in companies is presented together with the characteristics of the fuel balance. The final part of the article compares the value of the revenues to the budgets of local government units (communes) from the operating fee paid by entrepreneurs and expenditures of these municipalities on environmental protection, as additional support by these entities (2013–2015).

Coastal wetlands are important ecosystems for carbon storage and coastal resilience to climate change and sea-level rise. As such, changes in wetland habitat types can also impact ecosystem functions. Our goal was to quantify historical vegetation change within the Nisqually River watershed relevant to carbon storage, wildlife habitat, and wetland sustainability, and identify watershed-scale anthropogenic and hydrodynamic drivers of these changes. To achieve this, we produced time-series classifications of habitat, photosynthetic pathway functional types and species in the Nisqually River Delta for the years 1957, 1980, and 2015. Using an object-oriented approach, we performed a hierarchical classification on historical and current imagery to identify change within the watershed and wetland ecosystems. We found a 188.4 ha (79%) increase in emergent marsh wetland within the Nisqually River Delta between 1957 and 2015 as a result of restoration efforts that occurred in several phases through 2009. Despite these wetland gains, a total of 83.1 ha (35%) of marsh was lost between 1957 and 2015, particularly in areas near the Nisqually River mouth due to erosion and shifting river channels, resulting in a net wetland gain of 105.4 ha (44%). We found the trajectory of wetland recovery coincided with previous studies, demonstrating the role of remote sensing for historical wetland change detection as well as future coastal wetland monitoring.

Urban parks are key elements of the urban landscape. They provide important ecological, environmental, and social value as well as spaces for outdoor activities to contribute to urban sustainability. Reasonable accessibility is fundamental for people to take full advantage of the benefits of parks. Spatial interaction models are useful in many fields, especially in static systems. The proposed model has been validated for analyzing the accessibility of district parks in Hong Kong. The accessibility index was calculated using the population in catchment zones lying within a walking distance of 400 m, considering the population that the parks serve, the distance between residential areas and parks, the park area, and the facilities and current condition of green spaces in the parks. The results indicate that the index is strongly related to the spatial pattern of residential areas and the shape and spatial pattern of district parks. High accessibility is always associated with parks located in centers of population concentration rather than in the geographical centers of built-up areas. The catchment zones of district parks within walking distance only cover one-fourth of residential areas, and most residents do not have convenient access to reach parks on foot. The district parks were established without much concern for increasing accessibility. No districts have enough district parks to meet the needs of their residents. Future parks should preferably be elongated to serve more nearby residents, especially in extremely compact cities like Hong Kong. Full article

Transdisciplinary research (TDR) is discussed as a promising approach in land-use science and spatial research to address complex multifaceted “real-world problems” and to design strategies and solutions for sustainable development. TDR has become a widespread research approach in sustainability science and is increasingly promoted by research programmes and agencies (e.g., Future Earth and Horizon 2020). Against this backdrop, TDR can be considered a (social) innovation in the academic system, which is currently in the midst of an up-scaling diffusion process from a rather small TDR-advocating expert community to a broader science-practice community. We argue that this up-scaling phase also places TDR in a critical state as the concept potentially risks a type of “rhetorical mainstreaming”. The objectives of this study were to analyse how the challenging approach of TDR is currently adopted and implemented in the field of land-use research and to identify potential influencing factors. We studied 13 transdisciplinary research projects from Germany by performing qualitative interviews with coordinators, document analysis and participatory observation during meetings over a period of five years. Results show that the adoption level of the TDR concept varied widely among the studied projects, as did the adoption of the TDR indicators used in our analysis. In many of the investigated projects, we identified a clear lack of conceptual knowledge of TDR. In addition, we found that current academic structures limit the ability of researchers to thoroughly adapt to the requirements of TDR. We conclude that further communication and educational efforts that promote TDR are required. In addition, we advocate for the development of suitable funding instruments that support sustained research structures. Full article

Based on the consideration of the relative importance of sustainability-related objectives and the inherent nature of sustainable construction projects, this study proposes that the contractor can balance the levels of efforts and resources used to improve the overall project sustainability. A multi-objective trade-off model using game theory was established and verified through simulation and numerical example under a moral hazard situation. Results indicate that effort levels of the contractor on sustainability-related objectives are positively related to the outcome coefficient while negatively to the coefficients of effort cost of the relevant objectives. High levels of the relative importance of sustainability-related objectives contribute to high levels of effort of the contractor. With the variation in effort levels and the coefficient of benefit allocation, the project net benefit increases before declining. The function of project benefit has a marked peak value, with an inverted “U” shape. An equilibrium always exists as for the given relative importance and coefficients of the effort costs of sustainability-related objectives. Under this condition, the owner may offer the contractor a less intense incentive and motivate the contractor reasonably arranging input resources. The coefficient of benefit allocation is affected by the contractor characteristic factors and the project characteristic factors. The owner should balance these two types of factors and select the most appropriate incentive mechanism to improve the project benefit. Meanwhile, the contractor can balance the relative importance of the objectives and arrange the appropriate levels of effort and resources to achieve a sustainability-related objective. Very few studies have emphasized the effects of the relative importance of sustainability-related objectives on the benefits of sustainable construction projects. This study therefore builds a multi-objective trade-off model to bridge this research gap. This study sheds significant theoretical and practical insights regarding the objective management of sustainability-related objectives, as well as insights into the improvement of performance in sustainable construction projects.

Many rural areas face difficulty in how to motivate farmers to embark on diversified activities, such as tourism, while raising managerial efficiency. Thus, this paper conceptually and empirically evaluated how a farmer’s identity correlates with managerial efficiency since the connection between the two has not been explored fully. We have addressed this issue through examining farmers’ efforts in providing an emerging new educational tourism service by focusing on the Educational Dairy Farms in Japan. Conceptually, this paper classified farmers’ identity into two types: traditional identity as a simple farm producer offering an educational service as a volunteer, and, enlarged identity, which is oriented toward viability of a new service activity. Empirically, data envelopment analysis revealed that those with the enlarged identity realized a higher managerial efficiency although there was much room for improvement in overall managerial efficiency. Consequently, support measures with a wider perspective that include identity issues should be designed for capacity building of farmers who are conducting tourism. Full article

Landfill siting is a complex process. It is one of the major problems in waste management, where many factors should be taken into consideration when selecting a suitable site for landfill in any given area. At the present time, there are many random waste disposal sites distributed throughout Al-Hashimiyah Qadhaa in Iraq. In this study, the Geographic Information System (GIS) and the Analytical Hierarchy Process (AHP) were used to select the best sites for landfill. The process of selecting sites for landfill in Al-Hashimiyah Qadhaa comprised two steps. First, fifteen different criteria were mapped and incorporated into overlay analyses within GIS software to produce the final suitability index map for the site. The second step comprises the exclusion of unsuitable areas from the final map to simplify identification of the candidate sites for landfill in the study area. The weightings of criteria were identified using AHP, and the weightings of the sub-criteria of each criterion were determined based on multiple factors. In order to accommodate solid waste from 2020 until 2030, two suitable candidate landfill sites were determined which fulfill the required area of 1.013 km2 with areas of 1.374 km2 and 1.288 km2 respectively.

The non-revenue water (NRW) ratio in a water distribution system is the ratio of the loss due to unbilled authorized consumption, apparent losses and real losses to the overall system input volume (SIV). The method of estimating the NRW ratio by measurement might not work in an area with no district metered areas (DMAs) or with unclear administrative district. Through multiple regression analyses is a statistical analysis method for calculating the NRW ratio using the main parameters of the water distribution system, although its disadvantage is lower accuracy than that of the measured NRW ratio. In this study, an artificial neural network (ANN) was used to estimate the NRW ratio. The results of the study proved that the accuracy of NRW ratio calculated by the ANN model was higher than by multiple regression analysis. The developed ANN model was shown to have an accuracy that varies depending on the number of neurons in the hidden layer. Therefore, when using the ANN model, the optimal number of neurons must be determined. In addition, the accuracy of the outlier removal condition was higher than that of the original data used condition. Full article

In this paper we explore whether a number of elements influence the levels of corporate social responsibility (CSR) disclosure in the annual reports of Polish companies. These elements include the following: company size, profitability, financial leverage, industry environmental sensitivity, board size, women on the board, internationalization, and reputation. We use content analysis to determine the quality of CSR disclosures. We test our hypotheses using a Tobit regression analysis on a sample of 60 reports from Polish companies listed on the Warsaw Stock Exchange. We find industry environmental sensitivity to have significant influence on CSR disclosures. Our research findings also reveal a relationship between company turnover, duration of the stock exchange listing, inclusion in the Respect Index portfolio and foreign capital share, and the level of CSR disclosures. This study extends the scope of previous studies by including non-commonly used independent variables: the company’s internationalization and reputation. To the authors’ knowledge, it is the primary step to investigating CSR reporting practices coupled with the corporate characteristics in a Central and Eastern European country such as Poland. The paper contributes to the understanding of determinants of CSR disclosure and offers findings which are potentially useful for both theory and practice. Full article

To clarify its evolution and evolutionary mechanisms, the city of Xi’an is considered as an empirical case, using factor ecological analysis for modern times. Research results are concluded as follows: the types and affecting factors of social space continued to increase. Urban socio-spatial structure evolved from single-core pattern to single-core pattern with enclaves, and later showed a more mosaic tendency. The political and socio-economic backgrounds of different periods have had a great influence on the urban socio-spatial structure. The research results have theoretical significance for optimizing socio-spatial structure and understanding the urban space of Xi’an. Compared with studies of other cities in China and cities in western countries, the evolution of urban socio-spatial structure in China shows the characteristics of circle expansion and the gradual and stable transition under socialist ideology.

This research aims to investigate the relationship between interorganizational trust and control and their effects on the project success from the perspective of project owners. Based on relevant literature and the actual situation in the Chinese construction industry, trust was classified as calculative trust and relational trust, and control was classified as outcome control, behavior control, and social control. Results show that project owners’ distrust of contractors is independent of project owners’ trust of contractors. Calculative trust has a positive influence on all kinds of control. Relational trust has negative impacts on outcome control and behavior control and positive impacts on social control. Of the three kinds of control, outcome and behavior control have negative impacts on social control. All constructs have positive impacts on project success. Project managers should be aware that distrust has a positive influence on project success through the mediation effects of control. Similarly, social control is the most influential type of control, influencing the controller to internalize norms to complete project tasks. Full article

Efforts to decrease the water use within industry are mandatory to pursue product and process sustainability. Particularly, the European Union (EU) is at the top level for water consumption in industry, while some sectors, such as the food and beverage (F&B), are highly water-intensive with hundreds of liters per hour of consumed and, then, drained water. This article provides a systematic overview of the most innovative insights coming from an EU Eco-Innovation project dealing with greening the F&B industry through the design, prototyping, technical, economic, and environmental assessment of a wastewater closed-loop recovery and purification system. The system, tailored for a standard mid-size F&B company using 2–3 billion L/year of raw water, collects, purifies and recirculates the key produced wastewater streams with an overall recovery efficiency of about 56%. The proposed purification technology comes from the most efficient combination of membrane-based filtration methods, reverse osmosis (RO), and ultraviolet modules. Evidence from the technical design, full-scale on-site technology prototyping, net-present-value (NPV) analysis and system life-cycle-assessment (LCA) are presented concluding about the convenience of adopting the proposed solution to reduce costs and impacts on the environment.

Food security is increasingly influenced by multilateral trade systems and foreign trade policies implemented by national governments. Many of them are now concerned about the sustainability of food supply and the vulnerability of domestic food markets to price volatility, and seek to support domestic producers and protect themselves from increasing food imports. Such restrictions improve food self-sufficiency, but decrease food security. It is important to understand any changes that may have occurred in the food consumption pattern due to trade protectionism and to observe any nutritional implications of these changes. This paper employs the rational food security (RFS) assessment approach, which differentiates sources of food supply on the domestic market, assesses the influence of agricultural and trade frameworks on food consumption patterns, and complies consumption with the appropriate food intake threshold. In the case of Russia, the study demonstrates that the conventional consumption approach to self-sufficiency (FSCA) underestimates the food insecurity level by not accounting for nutrition factors. In addition, the gap between the FSCA and the RFS increases in times of protectionist trade policy and decreases when the agricultural and trade policy framework turns to liberalization. The paper concludes that trade protectionism challenges the sustainability of food supply by decreasing food availability and quality of food products, causes dietary changes, and threatens the food security of the country.

Contemporary urbanization appears as a conundrum especially in developing nations. This study will act as an accelerator to spill out snags caused by urbanization with a new approach in the development of sustainable infrastructure through Public–Private Partnerships (3Ps). This study first explains the complications generated by rapid urbanization in different infrastructural sectors in South Asian mega cities like Dhaka and Lahore. Second, the findings of the study elaborate on a new mechanism to adapt to Sustainable Development Goal 11 declared by the United Nations with the engagement of different stake holders working in different silos through 3Ps (like BOT, BOOT, BLT, DBF, PFI etc.). This study uses case studies as part of the research mixed methodology. Studies on Dhaka and Lahore including multi projects through 3Ps, and a detailed questionnaire survey based on critical risk factors from the Meta review of 3P literature are presented to establish the current status of sustainable development goals. This paper primarily contributes in two ways. First, by providing a new direction to policy makers to devise policies using a twofold approach i.e., grasp urbanization with sustainable infrastructure delivery by sustainable enactment of 3P projects. Second, bridge the knowledge gap by identifying the risk factors in the sustainable establishment of 3P projects in developing nations. Full article

Chinese resource-exhausted cities face more severe environmental pollution problems than other cities. In addressing these problems, the way local officials (usually senior party and government leaders) operate is very important, as their focus on political achievements may complicate how they manage environmental pollution in these cities. On the one hand, the traditional Gross Domestic Product-based quest for political achievement may lead top leaders to de-emphasize environmental pollution. On the other hand, changes made in 2003 to the way the performance of Chinese officials is evaluated have encouraged some local senior party and government leaders to pay more attention to environmental problems. Based on this, we analyze the relationship between political incentives and environmental pollution by applying the 2004–2014 panel data from 37 resource-exhausted cities. The findings reveal that firstly, among the factors which impact the environmental pollution of resource-exhausted cities, investment in fixed assets, foreign direct investment, industrial structure, per-capita education expenditure, and population density do not have a significant impact, thus indicating that local openness levels, the degree of industrial upgrading, and local investment in fixed assets are not the key variables in environmental pollution control. Secondly, the extent to which officials vie for political achievement affects environmental pollution in resource-exhausted cities. This depends upon whether the officials are municipal party secretaries or mayors; the former play a greater dynamic role in environmental pollution and have stronger robustness than the latter. The conclusion verifies both the existing authority structure of China and its effectiveness in the control of environmental pollution of resource-exhausted cities. That is to say, in contrast to the principles of the party committees, the mayors are in a subordinate position and often fail to fully and effectively exercise their functions. Accordingly, we point out that the selection of municipal party secretaries, rather than mayors, is particularly important in coming to terms with local environmental pollution. Full article

In order to solve problems caused by climate change, countries around the world should work together to reduce GHG (greenhouse gas) emissions, especially CO2 emissions. Power demand takes up the largest proportion of final energy demand in China, so the key to achieve its goal of energy-saving and emission reduction is to reduce the carbon emissions in the power sector. Taking Shenzhen as an example, this paper proposed a stochastic optimization model incorporating power demand uncertainty to plan the carbon mitigation path of power sector between 2015 and 2030. The results show that, in order to achieve the optimal path in Shenzhen’s power sector, the carbon mitigation technologies of existing coal and gas-fired power plants will be 100% implemented. Two-thirds and remaining one-third of coal-fired power plant capacities are going to be decommissioned in 2023 and 2028, respectively. Gas-fired power, distributed photovoltaic power, waste-to-energy power and CCHP (Combined Cooling, Heating, and Power) are going to expand their capacities gradually. Full article

Understanding the public transportation users’ preferences to long-distance travel modes would contribute to reasonable developing policies and resource allocation. This paper aims to explore the influencing mechanism of potential factors on the long-distance travel mode choice. A survey was conducted to collect the data. The analysis of variance (ANOVA) approach was applied to analyze the correlation relationship between potential factors and travel mode choice behavior. The results showed that, except gender, service demand for safety and departure time, all of the other factors significantly influenced the travel mode choice behavior. Specifically, passengers with higher education level and income level were more likely to choose high-speed railway (HSR) and plane; passengers caring about travel expense were more likely to choose ordinary train, whereas plane and HSR may be chosen more by passengers caring more about comfort, punctuality and efficiency; the more passengers were satisfied with travel modes’ service performance, the more they would be likely to choose them; the most competitive distance ranges for coach, ordinary train, HSR and plane were below 500 km, 500–1000 km, 500–1500 km and over 1500 km, respectively. Besides, the structural equation modeling (SEM) technique was applied to investigate the influencing mechanism of factors on the long-distance travel mode choice. The results revealed that travel distance was the most significant variable directly influencing passengers’ mode choices, followed by the service demand, performance evaluation, and personal attributes. Furthermore, personal attributes were verified to have an indirect effect on travel mode choice behavior by significantly affecting the service demand and performance evaluation. Full article

Organizations should support leaders in promoting their employees’ health in every possible way to achieve a sustainable workplace. A good way to support leaders could include getting feedback about their health-promoting behavior from their employees. The present study introduces an instrument (Health-Promoting Leadership Conditions; HPLC) that enables the provision of feedback about the leaders’ efforts to create health-promoting working conditions in seven key aspects: health awareness, workload, control, reward, community, fairness and value-fit. The instrument was used in employee surveys and in an online study, obtaining a sample of 430 participants. The results showed that all seven key aspects of health-promoting leadership can be assigned to a main factor of health-promoting leadership. In addition, the HPLC shows high construct validity with dimensions of stress, resources and burnout (Recovery-Stress- Questionnaire for Work [RESTQ-Work] and Maslach Burnout Inventory General Survey [MBI-GS]). The results indicate that the HPLC can be used as a basis on which to assess health-promoting leadership behavior with a focus on changing working conditions. By getting feedback about their leadership behavior from their employees, leaders can identify their potential and fields for improvement for supporting their employees’ health and developing a sustainable workplace.

The transformation of cities towards healthy urban living environments for all is a challenge that needs to be addressed through collaboration of all relevant sectors in a transdisciplinary research processes. This paper reports on the design and showcase implementation of a methodological approach, named Interactive Spatial Understanding Support System (ISUSS), that is intended to support interactive knowledge co-production and integration among practitioners and researcher in a specific local context. The approach involves the combined use of interactive maps on a MapTable and a rich picture. The goal is to stimulate, articulate and map stakeholders’ knowledge on environmental health issues to come to a shared problem understanding. Drawing on the rich seam of data gathered over the reflexive engagement with the participants in Dortmund, Germany, we explored incidences of a transdisciplinary process. Findings suggest that the approach has the potential to encourage communication and social learning geared towards a shared understanding of the holistic problem situation. Whilst locally embedded spatial knowledge was shared using interactive maps on the MapTable, the rich picture elicited issues linked to wider geographical scale as well as non-spatial drivers. The paper concludes discussing research needs to further explore the approach among various other groups, including citizens. Full article

The “Jatropha for Galápagos” (JFG) project in Ecuador aims to progressively replace diesel with jatropha oil in the generation of electricity in The Galápagos Islands. Thus, understanding and motivating the participation of jatropha suppliers is a priority for the sustainability of JFG. For this reason, the factors influencing their decision-making to participate in the project have been identified and analyzed using a binomial logit model. The results show that factors found to positively influence the likelihood of participation include, amongst others, the supplier’s experience within the project, their participation in local organizations, and the degree of satisfaction with the price of jatropha oil. In addition, children from producer families’ collaboration in the harvest of jatropha increases the overall likelihood of participation within the project. Similarly, the distance to the collection center positively influences the chances of participation. Conversely, those suppliers with higher wages and those who declared that jatropha harvest starts in April have a reduced likelihood of participating in the project. The findings obtained from this project can help decision-makers develop new measures to improve the sustainability of the project through initiatives to motivate the participation of jatropha suppliers in the program.

The aim of the paper is to investigate to what extent access to finance explains differences in entrepreneurial activity across European Union (EU) member countries. We use a dataset containing information across countries and time to investigate the determinants of entrepreneurial activity in twenty-five EU members over the period between 2007 and 2013. Our sample comprises both periods of difficult access to finance and periods of excessive liquidities. Employing a panel data model with fixed effects, we found a positive relationship between access to finance and entrepreneurial activities. Furthermore, we showed that this positive relationship is more important for the individuals who believe they have the required skills and knowledge to start a business. The results proved to be robust when we employed different measures of entrepreneurial activity and several proxies for access to finance. Our findings provide empirical evidence for the need of policy initiatives at national and EU level to facilitate the creation of sustainable new ventures. Full article

Land in rural China has been under a separate and closed management system for decades even after the urban land reform that started in the late 1980s. The blurred property rights over rural land have been hindering the rural welfare as surplus rural land in sub-urban areas cannot be circulated into more economic use without first being requisitioned by the state. This traditional conversion process creates a lot of problems, among them are the compensation standard as well as displacement of rural residents to the city, where they cannot find adequate welfare protection. The prolonged disparity in economic outcomes for rural and urban residents in China in the process of urbanisation has made the authority realise that land-based local finance is no longer an option. Coordinated Urban and Rural Development (CURD) ideology arises to set a level playing field by giving the rural residents comparable welfare status as their urban counterparts’ one. The CURD ideology is basically linked to the strategic development of the three main issues in the rural area of China, or in the Chinese terminology: San Nong. These three issues are rural villages, rural enterprises and rural farmers (nong cun, nong ye, nong min). CURD ideology is to preserve the livelihood of rural villages, facilitate and promote rural enterprises and increase the living standard of rural farmers. Most importantly, however, CURD policy package bestows rural residents with property rights over their farmland so that they could sub-co1ntract the user-rights to other urban commercial entities for higher benefits. While CURD policies are applied in a lot of different regions in China including Chongqing in the West, Qingdao in the North, Zhongshan in the South and Wuhan in the middle, we focus our examination in Chengdu as the Chengdu model has been widely documented and highly regarded as the most successful model in implementing the CURD strategies. From our case study, we find that CURD policies reduce the pressure for rural residents to migrate to the city for better job opportunities, which in turn reduce the need to expand the development scale, especially housing needs, of the urban configuration. Consequently, CURD ideology helps contribute to a more sustainable urbanisation process in China that accommodates and balances the needs and interests of both the city and rural residents.

This study assesses the impact of wood energy use under underutilized conditions of wood resources: the impact on promotion of forest maintenance practices (FMPs), user costs, and local economies, using the case of a local initiative in Nishiwaga, Iwate, Japan. We conducted two main analyses: resource and economic assessment. For resource assessment, we investigate whether wood supply from FMP residue is sufficient to sustainably satisfy new demand created by a local initiative in Nishiwaga, and in how much forest area can FMPs be performed to satisfy the demand. These questions are analyzed by linear programming. Regarding economic assessment, we investigate whether replacement of fossil fuel by wood energy brings economic benefit to a user and local economy using input–output analysis. Our overall findings demonstrated that the use of wood energy under underutilized situations can lead to an increase of implementations of FMPs and of domestic wood resource supplies from a short-term perspective that comes from residues of the FMPs. We also found that wood energy consumption introduces co-benefits in terms of reduced heating costs for users and a larger economic impact on the local economy than fossil fuel. Full article

This study aims to use the vernacular climatic strategies (VCS) of traditional dwellings in Bushehr, in the common residential buildings of this southern Iranian city (which is characterized by its hot and humid climate), and provide answers to the following question: What effects do VCS have in terms of energy consumption in these buildings? This study has been conducted at three levels. At the first level, three context-based climatic solutions including shading, natural ventilation, and insulation of external walls and roofs were identified and selected based on bibliographic study. At the second level, a case study reflecting the current typology of common residential buildings in Bushehr city was selected. A combination of the mentioned climatic solutions was used in the baseline case to create a developed model. Based on the space layout of the developed model and some design criteria, a series of proposed models was also created and modeled. The selected case study building was also used to establish a local weather station at a height of 12 m based on the roof, collecting local climate data which were then used for simulation to improve simulation accuracy. Finally, all models were simulated with the use of Design Builder software under natural ventilation conditions during moderate climatic periods of the year while split air-conditioning systems were used during hot and humid periods. The results showed reductions of 16% in energy consumption and 22% in CO2 emissions for the developed model, and reductions of 24–26% in energy consumption and 32–34% in CO2 emissions for the proposed models, as compared with the baseline model. Furthermore, all proposed models achieved lower annual energy consumption when compared with a selection of international sustainable low energy standards and domestic energy performance references for the Middle East region. Further studies are also recommended, and there is potential for combining VCS with other solutions such as on-site renewable energies. Full article

The state of the urban carbon cycle is an important indicator for managing fossil energy consumption and land resources and it is also a basis for the planning of urban eco-services and urban sustainable development. This paper aims to analyze the spatial distribution of the carbon cycle of the mono-centric cities, based on the von Thünen concentric ring theory, using the InVEST (Integrated Valuation of Ecosystem Services and Trade-offs) model and an atmospheric diffusion model to assess the carbon sequestration capacity of land cover/use, to estimate carbon emissions, discuss influencing factors that determine changing trends in carbon sequestration capacity and to predict the changing law of the carbon sequestration eco-service spatial pattern based on scenario simulations. The results of this study show: (1) In Guang’an, the spatial distribution of the carbon cycle follows a concentric ring pattern. From the concentric ring pattern center, the first annular zone represents the carbon emissions, which lie at the concentric ring center; the second annular zone represents the carbon sequestration service; and the third annular zone represents stable carbon stock; (2) The structure of the concentric ring has not changed, but the spatial distribution of carbon sequestration and carbon density has changed due to fossil energy consumption and land cover/use change. From 2014 to 2016, the carbon emission zone shrunk, while the carbon sequestration service zone expanded and the carbon density increased—the increase of forest land is the main factor in the increase of carbon density; (3) The current carbon sequestration eco-service in Guang’an is not the best development condition. The planning of urban eco-service spatial patterns and land cover/use should consider the protection of cultivated and ecological areas at the same time. The results of this study can help the government implement spatial planning and regional policy interventions for land cover/use and eco-service. Full article

Sustainability issues in higher educational institutions’ (HEIs) research, especially in the social science field, have attracted increasing levels of attention in higher education administration in recent decades as HEIs are confronted with a growing pressure worldwide to increase the efficiency of their research activities under a limited volume and relatively equitable division of public funding resources. This paper introduces a theoretical analysis framework based on a data envelopment analysis, separating the social science research process into a foundation stage and a construction stage, and then projecting each HEI into certain quadrants to form several clusters according to their overall and stage efficiencies and corresponding Malmquist Productivity Indices. Furthermore, the interfaces are formed in each cluster as feasible potential improvement directions. The empirical results in detail are demonstrated from a data set of Chinese HEIs in Jiangsu Province over the Twelfth Five-Year period as offering a closer approximation to the “China social science research best practice”.

This paper analyses seven metropolitan regions that are all experiencing rapid motorisation and are perhaps appearing to capitulate to the automobile. Through 20 years of changes, evidenced in systematic data from the mid-1990s, a different perspective is found. None of the urban regions appear near to or even capable of becoming automobile cities. Physical limits are already being reached that make higher levels of private motorised mobility very problematic if transport systems are to remain functional and the cities livable. These limits appear already to be reversing the decline in non-motorised modes and creating an upturn in transit systems, especially urban rail. That these cities have been able to either hold their own, or somewhat increase their share of total motorised mobility by transit over a 20-year period, is some indication that they are ‘hitting mobility walls’ much sooner in the motorisation path than cities in North America and Australia, which grew up with and were designed around the spatial needs of cars. Like many cities in the developed world that have shown a decoupling of car use and total passenger mobility from GDP growth from 1995 to 2005, there is now evidence that this is happening in less wealthy cities. This is important because it assists global and local goals for reduced CO2 from passenger transport, while allowing for economic progress. Such evidence suggests that automobile dependence is not an irresistible force in emerging economies. Full article

The performance evaluation of satellite-based precipitation products at local and regional scales is crucial for modification in satellite-based precipitation retrieval algorithms, as well as for the provision of guidance during the selection of substitute precipitation data. This study evaluated the performances of three Tropical Rainfall Measuring Mission (TRMM) Multi-satellite Precipitation Analysis (TMPA) products (3B42V6, 3B42RT and 3B42V7) with a reference to rain gauge observations in the Hunza River basin, northern Pakistan. Multi-spatial (pixel and basin) and temporal (daily, monthly, seasonal and annual) resolutions were considered for performance evaluation of TMPA products. Results revealed that the spatial pattern of observed precipitation over the basin was adequately captured by 3B42V7 but misplaced by 3B42V6 and 3B42RT. All TMPA products were unable to capture the intense precipitation events. On the daily time scale, the performance of TMPA products was very poor over both spatial scales. 3B42V6 underestimated the precipitation (31.25% and 44.27% on pixel and basin scales, respectively). By contrast, 3B42RT significantly overestimated the precipitation (47.91% and 38.62% on pixel and basin scales, respectively), while 3B42V7 showed overestimation (17.30%) on pixel scale and slight underestimation (6.24%) on the basin scale. On the seasonal scale, TMPA products showed significant biases with observed precipitation data. We found that the TMPA products performed relatively better on monthly and annual time scales and overall performance of 3B42V7 product was better than that of 3B42V6 and 3B42RT. The bias in 3B42V7 was improved by 85.90% compared with 3B42V6 and by 116.16% compared with 3B42RT. Thus, it is concluded that the TMPA products were unreliable to capture the intense precipitation events and retain high errors on daily and seasonal scales. Therefore, caution should be considered while using these precipitation estimates as a substitute data in hydrology, meteorology and climatology studies in Hunza River basin. However, due to the reasonable performance of monthly and annual 3B42V7 estimates, these can be used as an acceptable substitute for applications in the region. Full article

The objective of this research is to analyze regional economic difference and explore the influencing factors, which would eventually provide an effective foundation to narrow the regional economic differences. In this paper, a new regional economic difference model is established considering the interactions between the spatial weight and human capital and foreign direct investment (FDI). With the panel data from twelve western provinces in China, the empirical research is conducted by adopting feasible generalized least squares (FGLS) fixed effects model. The preliminary results show that: (1) the spatial spillover effect of human capital and FDI is significant to the formation of regional economic difference; and (2) the total capital formation, government expenditure, FDI, human capital and patent application authorization are positively correlated with GDP growth per capita, while the number of medical institutions is negatively correlated with GDP growth per capita. In addition, the robust test is carried out for validation by using the filter variable method, spatial lag model and spatial error model. The robustness test results show that the results of the FGLS fixed effects model are validated by the filter variable method. The other two robust test results show that: (1) the total capital formation and the fixed asset investment is of 99.9% significance, which represents that they play a key role in the formation of economic development difference; and (2) the coefficients’ symbols of the other variables are consistent with the FGLS fixed effect model but a little different on the significances, which enhance the effectiveness of the proposed regional economic difference model.

Various types of sensors technologies, such as machine vision and global positioning system (GPS) have been implemented in navigation of agricultural vehicles. Automated navigation systems have proved the potential for the execution of optimised route plans for field area coverage. This paper presents an assessment of the reduction of the energy requirements derived from the implementation of optimised field area coverage planning. The assessment regards the analysis of the energy requirements and the comparison between the non-optimised and optimised plans for field area coverage in the whole sequence of operations required in two different cropping systems: Miscanthus and Switchgrass production. An algorithmic approach for the simulation of the executed field operations by following both non-optimised and optimised field-work patterns was developed. As a result, the corresponding time requirements were estimated as the basis of the subsequent energy cost analysis. Based on the results, the optimised routes reduce the fuel energy consumption up to 8%, the embodied energy consumption up to 7%, and the total energy consumption from 3% up to 8%. Full article

The relationship between corporate environmental performance and corporate financial performance has been extensively studied in developed countries, and has received less attention in developing countries. For this reason, the main objective of this paper is to examine the effect of corporate environmental performance on corporate financial performance during a global financial crisis, depending on the economic development level of the country where a firm is located. To this end, we obtain data for a sample of 2982 large firms from 2008 to 2015. We apply Petersen’s approach to these data, adjusting the standard errors for clustering by both firm and year. The results obtained show that the adoption of environmental practices significantly and positively affects the corporate financial performance in developed and developing countries. However, this effect is stronger for firms located in developing countries than those located in developed countries. Full article

In an increasingly competitive market environment, understanding why consumers purchase fresh produce from farmers’ markets is pivotal to understanding the markets’ value and to strengthening the rural economy. This is the first study to employ a means-end chain (MEC) framework to analyze the motivations underlying consumer preference for farmers’ markets. The linkages between these motivators are important steps in understanding why consumers purchase fresh produce from farmers’ markets. Based on in-depth interviews with 212 shoppers at the farmers’ markets in the Klang Valley, Malaysia, we identified the attributes ‘fresh’, ‘nearby’, ‘variety’, and ‘cheap’ as the means of achieving self-directed personal values (e.g., ‘expenses are better managed’), security values (‘live longer’), and benevolent values (e.g., ‘close the ties’). The insights gained should prove useful to policy-makers and to the farmers’ market sector, allowing them to more effectively communicate with consumers from the basis of a better understanding of the attributes, benefits, and personal values influencing them.

Waste-to-energy (WtE) incineration technology is widely used to solve the energy supply, greenhouse gas emissions, and waste generation problems in urban areas. In Taiwan, there are new laws and regulations that would affect greenhouse gas management of WtE incineration plants. This research aims to identify or raise key issues to be promoted for WtE incineration plants due to existing management systems and complex issues mixed with GHG, energy, and solid waste treatment. This study utilizes inventory analysis and social LCA (SLCA) approach on GHG management of WtE incineration plants in Taiwan to systematically identify materiality issues to be promoted. According to the results of materiality analysis for SLCA, this study generalizes four stakeholders, nine subcategories, and their 15 inventory indicators; and concludes that, among assessment results of 15 inventory indicators, three indicators are at a high level, four at a medium level, and eight at a low level. In total, 12 materiality issues are recognized. This study suggests WtE incineration plants should consider the following materiality issues with respect to priority: a systematic database and calculation methods, the goal and criteria of the laws and regulations, technology development toward circular economy and promotion activity or opportunity for local community and organization level.

China is faced with great challenges for its low urbanization quality and high water stress. Moreover, the relationship between urbanization quality and water resources is still ambiguous. Therefore, we firstly constructed an urbanization quality index (UQI) and a water resources constraint intensity index (WRCI) by a fuzzy comprehensive evaluation method with multi-objectives and multi-hierarchies. Secondly, based on the concept and method of “coupling” and “decoupling”, we provided a method to explore the coordinated and uncoordinated relationships between UQI and WRCI from a spatiotemporal perspective. Finally, we used the statistical data of 51 prefecture level regions in Northwest China from the period 2000–2014 to analyze the spatiotemporal variation of the coupling and decoupling relationships between UQI and WRCI. Results show that, the UQI and WRCI in the whole Northwest China both belonged to low level, and that they had achieved strong decoupling during 2000–2014. However, the coupling and decoupling relationships between UQI and WRCI in Northwest China had great spatial disparity. From the HL-type regions (regions with high UQI & low WRCI) and strong decoupling type regions, we can find key development areas of Northwest China, where the relationships between UQI and WRCI were optimal and coordinated. From the LH-type regions (regions with low UQI & high WRCI) and strong negative decoupling type regions, we can find key problem areas, where the relationships between UQI and WRCI were the worst and uncoordinated. Our study developed an effective method for evaluating the sustainable development level of urbanization constrained by water resources in Northwest China and similar regions, which is significant for the New-Type Urbanization research in China.

Using a large dataset from the specialized apple production sites of China and multiple econometric methods, we identify the main determinants of farmers’ land rental decisions and the effects from renting land in on their investment and economic welfare. It is found that having more effective cultivated land before renting in has a significantly negative effect on the land rented in, that households with rich land endowments or large areas of land rented in usually invest more in fixed assets, and that efficient provisions of credit and insurance are helpful to encourage investments in fixed assets. As a result, renting in land generates gains in terms of agricultural income, total income, and productive expenditure. Full article

There is a broad range of literature on individuals who mediate at the boundaries between science and policy. However, there seems to be little empirical evidence on the goals and strategies of knowledge brokers, even though they appear to be becoming increasingly important in the field of environmental science and policy. This paper aims to improve the understanding of why and how knowledge brokers operate through an analysis of 27 in-depth interviews. It demonstrates that they see themselves as (strategically) sensitive to all stakes and stakeholders involved, possess a large network, and act without interests. They appear to act strategically in two different settings: on stage, where the collaboration of all stakeholders is needed, and backstage, where the knowledge broker steers the process on his/her own. Furthermore, our research suggests that the (perceived) credibility and legitimacy of the knowledge broker is more important to the process than the degree of credibility and legitimacy of the knowledge used in the decision-making process, and that it would be advisable to deploy knowledge brokers proactively, instead of reactively, which could lead to ‘incident politics’.

This study investigated temporal variabilities and trends of rainfall and discharges in Tana River Basin in Kenya using Mann–Kendall non-parametric test. Monthly rainfall data from ten stations spanning from 1967 to 2016 and daily streamflow data time series of observations from 1941 to 2016 (75 years) were analyzed with the aim of capturing and detecting multiannual and seasonal variabilities and monotonic trends. The results for the datasets suggested that the streamflow is largely dependent on increasing rainfall at the highlands. The rainfall trends seemed to have been influenced by altitudinal factors. The coefficient of variation of the ten rainfall stations ranged from 12% to 17% but 70% of rainfall stations showed negative monotonic trends and 30% show significant trends. The streamflow showed statistically significant upward monotonic trend and seasonal variability indicating a substantial change in the streamflow regime. Although the increasing trend of the streamflow during this period may not pose future risks and vulnerability of energy and irrigated agricultural production systems across the basin, variability observed indicates the need for enhanced alternative water management strategies during the low flow seasons. The trends and time series data indicate the potential evidence of climate and land use change and their impacts on the availability of water and sustainability of ecology and energy and agricultural production systems across the basin. Variability and trends of rainfall and streamflow are useful for planning studies, hydrological modeling and climate change impacts assessment within Tana River Basin. Full article

The importance of research and development (R&D) for business sustainability have gained increasing interests, especially in the high-tech sector. However, the efforts of R&D might cause complex and mixed impacts on the financial results considering the associated expenses. Thus, this study aims to examine how R&D efforts may influence business to improve its financial performance considering the dual objectives: the gross and the net profitability. This research integrates a rough-set-based soft computing technique and multiple criteria decision-making (MCDM) methods to explore this complex and yet valuable issue. A group of public listed companies from Taiwan, all in the semiconductor sector, is analyzed as a case study. More than 30 variables are considered, and the adopted soft computing technique retrieves 14 core attributes—for the dual profitability objectives—to form the evaluation model. The importance of R&D for pursuing superior financial prospects is confirmed, and the empirical case demonstrates how to guide an individual company to plan for improvements to achieve its long-term sustainability by this hybrid approach.

The present study aims to assess the safety-climate level in Taiwan’s metal industries, as well as to identify the influence of workers’ backgrounds on the safety climate. An earlier report showed that a poor safety culture was related to the cause of accidents in Taiwan’s traditional manufacturing industries. This study surveyed a total of 839 workers who voluntarily participated and completed the safety-culture questionnaires. These workers were from a Taiwanese metal company and its five satellite companies. Three safety-climate factors, namely safety perception, safety communication and safety-management systems, were assessed. Confirmatory factor analysis (CFA) was conducted by developing structural equation modeling to ensure the questionnaire’s validity. The influence of workers’ backgrounds on the safety climate was identified by using one-way ANOVA. The reliability result of the questionnaire was above the acceptable level. The overall safety-climate score was 4.22 out of a five-point scale for safety perception, 4.23 for safety-management systems and 3.97 for safety communication. The scores indicate a good level of safety climate, with room for improvement in safety communication. Additionally, the influence of workers’ backgrounds on the safety climate was confirmed. Based on the validity test, it was also found that the questionnaire could be improved by reconstructing its questions in its development process in order to increase the safety-climate model’s reliability and validity, as well as its model fit.

While there is little doubt that social networks are essential for processes of implementing social innovations in community education such as Climate Change Education (CCE) or Education for Sustainable Development (ESD), scholars have neglected to analyze these processes in the multilevel governance system using Social Network Analysis. In this article, we contribute to closing this research gap by exploring the implementation of CCE and ESD in education at the regional and global levels. We compare the way CCE is negotiated and implemented within and through the global conferences of the UN Framework Convention on Climate Change (UNFCCC) with the way the UN Decade of ESD is put into practice through networks in five different German municipalities. We argue that the role of social networks is particularly strong in policy areas like CCE and ESD, which are best characterized as multi-level and multi-actor governance. Based on data derived from standardized surveys and from Twitter we analyze the complex interactions of public and private actors at different levels of governance in the two selected policy areas. We find, amongst others, that the implementation of CCE and ESD in community education depends in part on actors that had not been assumed to be influential at the outset. Furthermore, our analyses suggest the different levels of governance are not well integrated throughout the phases of the policy innovation cycle. Full article

Peer-firm strategies are a critical factor for corporate finance, and corporate social responsibility (CSR) is the main trend for evaluating the behavior of firms. On the basis of the connection between peer strategy and CSR, this paper explores the CSR strategies employed by a sample of Chinese firms during the 2008–2015 period. Our two main empirical findings are as follows. First, the CSR strategies of firms have a positive effect on their CSR behavior. Second, when there is the CSR gap between firms and peer firms, firms will feel the pressure from stakeholders and the public and improve the level of CSR performance. Our paper enriches empirical research on the CSR behavior of Chinese firms. Full article

Consumers have a dual role as economic actors who purchase products and as citizens comprising society. Thus, consumers may experience conflict between pursuing personal values (i.e., low price and high quality) and social values (i.e., equity and common good). In addition, these choices can be affected by governmental regulation of retail markets. This study aimed to identify consumer perspectives toward socially responsible consumption (SRC) in the choice of grocery store format and to investigate actual store choice behavior across consumer groups with those different perspectives while considering the role of retail regulation. For this purpose, we conducted a Q methodological study in which 30 South Korean consumers rank-ordered 40 statements regarding SRC. After performing Q factor analysis using PQ-Method software, we classified four distinctive consumer groups: “ethical conformist”, “market liberalist”, “ambivalent bystander”, and “internally conflicted”. After investigating similarities and differences between these consumer groups, we found major criteria for understanding consumer perspectives to SRC such as the priority of values pursued, the experience of a value-action gap, and internal conflicts in the decision-making process.

The drive to expand renewable energies is often in direct conflict with sustainable development goals. Thus, it is important that energy policies account for potential trade-offs. We assess the interlinkages between energy, food, water and land, for two case studies, Okinawa and Sogn og Fjordane. We apply a range of assessment methods and study their usefulness as tools to identify trade-offs and to compare the sustainability performance. We calculate cross-sectoral footprints, self-sufficiency ratios and perform a simplified Energy-Water-Food nexus analysis. We use the latter for assessing scenarios to increase energy and food self-sufficiency in Okinawa, while we use ecosystem service (ESS) accounting for Sogn og Fjordane. For Okinawa, we find that constraints on the energy, food and water sectors urgently call for integrated approaches to energy policy; for Sogn og Fjordane, the further expansion of renewables comes at the expense of cultural and supporting ESS, which could outweigh gains from increased energy exports. We recommend a general upgrade to indicators and visualization methods that look beyond averages and a fostering of infrastructure for data on sustainable development based on harmonized international protocols. We warn against rankings of countries or regions based on benchmarks that are neither theory-driven nor location-specific. Full article

Recent years have witnessed a revived interest in ancient wheats on account of their health-promoting properties. The aim of this study was to determine selected physical properties of hulled and hulless kernels of ancient wheats for optimizing the parameters of seed processing operations such as husking, cleaning, and sorting. The geometric parameters (length, width and thickness), mass, and angle of external friction (on steel and PVC) of hulled and hulless spelt, emmer, and einkorn kernels were determined. The spikelets and kernels of ancient wheats are characterized by similar physical properties and differ most considerably in mass. Full article

Reference Evapotranspiration (ETo) and soil moisture deficit (SMD) are vital for understanding the hydrological processes, particularly in the context of sustainable water use efficiency in the globe. Precise estimation of ETo and SMD are required for developing appropriate forecasting systems, in hydrological modeling and also in precision agriculture. In this study, the surface temperature downscaled from Weather Research and Forecasting (WRF) model is used to estimate ETo using the boundary conditions that are provided by the European Center for Medium Range Weather Forecast (ECMWF). In order to understand the performance, the Hamon’s method is employed to estimate the ETo using the temperature from meteorological station and WRF derived variables. After estimating the ETo, a range of linear and non-linear models is utilized to retrieve SMD. The performance statistics such as RMSE, %Bias, and Nash Sutcliffe Efficiency (NSE) indicates that the exponential model (RMSE = 0.226; %Bias = −0.077; NSE = 0.616) is efficient for SMD estimation by using the Observed ETo in comparison to the other linear and non-linear models (RMSE range = 0.019–0.667; %Bias range = 2.821–6.894; NSE = 0.013–0.419) used in this study. On the other hand, in the scenario where SMD is estimated using WRF downscaled meteorological variables based ETo, the linear model is found promising (RMSE = 0.017; %Bias = 5.280; NSE = 0.448) as compared to the non-linear models (RMSE range = 0.022–0.707; %Bias range = −0.207–−6.088; NSE range = 0.013–0.149). Our findings also suggest that all the models are performing better during the growing season (RMSE range = 0.024–0.025; %Bias range = −4.982–−3.431; r = 0.245–0.281) than the non−growing season (RMSE range = 0.011–0.12; %Bias range = 33.073–32.701; r = 0.161–0.244) for SMD estimation.

Energy consumption in the form of fuel or electricity is ubiquitous globally. Among energy types, electricity is crucial to human life in terms of cooking, warming and cooling of shelters, powering of electronic devices as well as commercial and industrial operations. Users of electronic devices sometimes consume fluctuating amounts of electricity generated from smart-grid infrastructure owned by the government or private investors. However, frequent imbalance is noticed between the demand and supply of electricity, hence effective planning is required to facilitate its distribution among consumers. Such effective planning is stimulated by the need to predict future consumption within a short period. Although several interesting classical techniques have been used for such predictions, they still require improvement for the purpose of reducing significant predictive errors when used for short-term load forecasting. This research develops a near-zero cooperative probabilistic scenario analysis and decision tree (PSA-DT) model to address the lacuna of enormous predictive error faced by the state-of-the-art models. The PSA-DT is based on a probabilistic technique in view of the uncertain nature of electricity consumption, complemented by a DT to reinforce the collaboration of the two techniques. Based on detailed experimental analytics on residential, commercial and industrial data loads, the PSA-DT model outperforms the state-of-the-art models in terms of accuracy to a near-zero error rate. This implies that its deployment for electricity demand planning will be of great benefit to various smart-grid operators and homes. Full article

In Japan, terraced paddies in mountain villages are symbolic of the traditional landscape, but they are gradually being abandoned. To compare plant-derived C and N among land uses, we compared adjacent forest floor (FF), agricultural paddy (AP), and post-agricultural paddy (PP) sites. Long-term litter accumulation could explain the significantly higher litter C and belowground biomass C in FF than in AP and PP. The low-density-fraction (LF) soil C was significantly higher in FF than in PP and better reflected land use than the whole-soil C. The AP soil held more N than FF and PP at 20–30 cm, associated with higher LF soil N. Periodic tillage in AP maintains the LF soil N, but N supplied to the surface soil reduced with depth following abandonment. Differences in recycling of organic matter and nutrients among land uses are crucial to plant-derived C and N contents of soil. Full article

The analysis and optimization of an organic Rankine cycle (ORC) used as a bottoming cycle in the Brayton/ORC and steam Rankine/ORC combined cycle configurations is the main focus of this study. The results show that CO2 and air are the best working fluids for the topping (Brayton) cycle. Depending on the exhaust temperature of the topping cycle, Iso-butane, R11 and ethanol are the preferred working fluids for the bottoming (ORC) cycle, resulting in the highest efficiency of the combined cycle. Results of the techno-economic study show that combined Brayton/ORC cycle has significantly lower total capital investment and levelized cost of electricity (LCOE) compared to the regenerative Brayton cycle. An analysis of a combined steam Rankine/ORC cycle was performed to determine the increase in power output that would be achieved by adding a bottoming ORC to the utility-scale steam Rankine cycle, and determine the effect of ambient conditions (heat sink temperature) on power increase. For the selected power plant location, the large difference between the winter and summer temperatures has a considerable effect on the ORC power output, which varies by more than 60% from winter to summer.

With the rapid development of China’s manufacturing, energy consumption has increased rapidly, and this has become a major bottleneck affecting the sustainable development of China’s economy. This paper deduces and constructs a homologous grey prediction model with one variable and one first order equation (HGEM(1,1)) for forecasting the total energy consumption of China’s manufacturing based on the Grey system theory. Both parameter estimation (PE) and the deduction of the final restored expression (FRE) of the HGEM(1,1) model are all from the time response expression of the whitenization differential equation, which solves the ‘non-homologous’ defects of PE and FRE with traditional grey prediction models. HGEM(1,1) has good performance and can unbiasedly simulate a homogeneous/non-homogeneous exponential function sequence and a linear function sequence. Then, the HGEM(1,1)model is used to simulate and forecast the total energy consumption of China’s energy manufacturing, and the results show that the comprehensive performance of this model is much better than that of the classic Grey Model with one variable and single order equation, GM(1,1) for short and the frequently-used Discrete Grey Model with one variable and single order equation, DGM(1,1) for short. Finally, we forecast the total energy consumption of China’s manufacturing industry during the years 2018–2024. The results show that the total energy consumption in China’s manufacturing is slowing down but is still too large. For this, some measures, such as optimizing the manufacturing structure and speeding up the development and promotion of energy saving and emission reduction technologies, to ensure the effective supply of energy in China’s manufacturing industry are suggested.

Ghana’s economic development relies largely on the mining industry, but the ecological cost is very high, particularly for the small-scale sector. To ascertain and give an account of the ecological pressures from the small-scale gold mining sector, we quantified and appraised the ecosystems (land cover types) degradation due to mining land use along portions of the renowned Pra River basin of Ghana. The study classified and analysed high-quality Landsat image data (1986–2016) to monitor processes and changes in the river basin and adopted the Ecosystem Service Value (ESV) model to quantify the forgone value in monetary term. The results revealed that the initial ESV of 17.69 million US$ in 1986 increased to 18.40 million US$ in 2002 for the study landscape with the small-scale mining sector accounting for 8.4% of the trade-off costs. The expansion of forest areas and its higher value coefficient (VC) was, however, prevalent and this resulted in a net positive change during this period. However, in 2016, out of the total ESV of 14.63 million US$ obtained, the small-scale mining activities accounted for 36.8% of the trade-off costs. The substantial increase in trade-off costs with a subsequent decrease in ESV in the study landscape, following the intensification of small-scale gold mining, indicates that their activities have been degrading the watershed ecosystem and are, therefore, unsustainable. The study affirms the need for policymakers/government to review the laws, particularly on post-mining monitoring schemes to deter illegal miners and support the registered small-scale miners who are willing to implement land rehabilitation activities.

While eco-friendly apparel has been made available in markets, turning this environmental innovation into companies’ competitive advantage has been challenging. The purpose of the study is to better understand consumers’ eco-friendly apparel consumption and to examine whether gender plays a role in consumer attitudes toward the product. Both male and female consumers’ green self-identity, cognitive and affective involvement, as well as their patronage intention, were examined and compared. The results showed that men and women were motivated by different factors. For men, cognitive involvement was a prominent determinant of their patronage intention and mediated the relationship between their green self-identity and intention. For women, green self-identity was the only factor that motivated their patronage intention for eco-friendly apparel. The findings provide empirical evidence and directions that could help marketers to identify their consumer characteristics and market segments and to develop more efficient eco-friendly apparel market communication strategies in the U.S. Full article

According to Hofstede’s theory of cultural dimensions, cultures differ in cultural values and norms; values and norms that may influence differences in trendsetting, creative traits, and behaviors, and pro-environmental behaviors. Further, because men and women have been socialized within particular cultures, gender differences may exist in trendsetting, creative traits and behaviors, and pro-environmental behaviors. Trendsetters have characteristics that are interrelated with creative traits and behaviors, perhaps inclining them to endorse pro-environmental behaviors. However, the interrelationships among these variables remain unexplored. Thus, the purpose of this study was to examine these three variables among college students in South Korea and the United States (U.S.), specifically looking at cultural and gender differences. Participants were 225 Korean college students and 221 U.S. college students. Questionnaires included demographic items and scales measuring trendsetting, creative traits and behaviors, and pro-environmental behaviors. Data analyses included descriptive statistics, Cronbach’s alpha reliability, MANOVA, ANOVA, and SNK posthoc test. Results show that U.S. (vs. Korean) students indicated greater trendsetting and creative traits and behaviors but not greater pro-environmental behaviors. Fashion trendsetting groups in both Korea and the U.S. differed in creative traits and behaviors and pro-environmental behaviors. Among Korean trendsetting groups, reluctant adopters scored lowest on creative traits and behaviors and pro-environmental behaviors. Among U.S. trendsetting groups, trendsetters the scored highest on creative traits and behaviors and pro-environmental behaviors; reluctant adopters scored lowest on pro-environmental behaviors.

Government support systems are crucial for export SMEs (Small to Medium Enterprises) to cope with growing international environmental regulations. However, empirical studies show a limited research area to explore the performance of export SMEs with the help of government support systems to meet international environmental regulations. This study draws implications on the relationship between government support and corporate performance on export SMEs between two countries: Korea and China. Based on 350 samples from Korea and 320 from China, we diagnosed government supports most positively affects corporate performances in the area of eco-innovation. While education, certificate, and tax supports were less pressing areas to support, no significance was found in information support. Furthermore, we found that eco-innovation is the strongest motive to accelerate corporate performance. Finally, the support of Chinese government on firms seems to be more affective when compared to Korean government support. Full article

Developing a more resilient food system based on sustainable food production and consumption is of major concern in creating food security. One issue in this complex field concerns the scale of the food system. Trends and tendencies show that the interest for local food has increased the last decade in Sweden, as well as in other parts of the world. Although the concept “local food” is commonly used, research shows that there is no single definition of it, instead definitions and meanings vary widely. This has led to a need by consumers of clearer information when buying “local food”. Several main actors in the Swedish food sector have joined forces to meet this issue. This paper contributes to knowledge on definitions, interpretations, and practice on local food by presenting views and opinions among different actors in the food chain in a Swedish context, but also in the light of an international pilot study. Main findings concern how the meaning of “local food” related to production, processing, raw material, and distance differs among stakeholders in the food chain. A majority stated that the basic meaning of “local food” concerns both the production and consumption within a certain geographical area. Full article

As thick rock partings delay the efficient mining of coal seams and constrain the sustainable development of coal mines, an innovative extraction method for a coal seam with thick rock parting was proposed. The coal seams were divided into different sub-zones according to the thickness of rock parting and then the sub-zones were mined by separately using three mining schemes involving full-seam mining, combined mining using backfill and caving (CMBC), and reducing height mining. Afterwards, the study introduced the basic mechanism and key devices for the CMBC and analysed the working state of the backfill support in detail. Moreover, the method for calculating the length of the backfill zone was proposed to design the length of backfill zone and the influences of four factors (including bulking coefficient) of rock parting on the length of the backfill zone were also explored. By taking the No. 22203 panel, Buertai mine, Inner Mongolia, China as an example, the mined coal resource by using the CMBC extraction method will increase by 1.83 × 106 tons and the recovery ratio will rise from 56.2% to 92.4% compared with mining of the 2-2 upper coal seam alone. Moreover, by applying CMBC, a series of environmental and ecological problems caused by rock parting is reduced, which can improve the environment in mined areas. The research can provide technological guidance for mining panels of a coal seam with a thick rock parting and the disposal thereof under similar conditions. Full article

Natural disasters can cause abrupt disturbances in coastal wetlands, affecting the social perception of ecosystem services (ES). The Tubul-Raqui coastal wetland is one of the most important wetlands in south-central Chile. Rich in biodiversity, these wetlands provide ES to a population of 2238 inhabitants. The recent MW = 8.8 earthquake of 2010 caused a coastal uplift of 1.4 m and substantial morphological, social, and environmental changes. This paper analyzes the social perceptions of the inhabitants of the village of Tubul-Raqui following a large earthquake disturbance with regards to ES provision frequency and their future changes. A statistically representative semi-structured survey was conducted (175 valid surveys) and the data interpreted through factor analysis and statistical tests for independent categorical variables. The perception of cultural and regulating services was significantly greater than that of provisioning services, which were probably the most affected by the earthquake. Residents identified habitat for species, recreation, and hazard regulation as the most important ES. Perception was influenced by the categorical variables of gender, age, and ethnicity; for example, hazard regulation services varied strongly by gender. According to the respondents, the availability of ES will remain stable (50%) or decrease (40%) in the next 50 years, mainly due to anthropogenic drivers; the effect of natural disasters was not mentioned among the main drivers of change.

This paper aims to establish the link between tourists’ perceptions on cultural offers and their overall satisfaction, and explore the implication of this link for sustainable tourist destination management. Assessing online customers’ reviews, this study identifies a positive correlation between visitors’ perspectives and experiences at the on-site cultural centre and visitors’ destination satisfaction. It suggests that the on-site cultural centre plays a critical role in building up visitors’ perception on cultural attributes of the destination, and its impact on visitor satisfaction is a double-edged sword. Visitors’ positive perspectives on the cultural centre enhance visitors’ experiences and contribute to their destination satisfaction; however, not only does a negative perspective on their cultural and spiritual experience compromise visitors’ satisfaction, but also subsequent negative online reviews damage the destination image and discourage visitor return/visit. The findings help destination management organisations to better understand visitors’ preference for cultural centres and therefore to improve visitors’ cultural experience. This paper appeals for further study of on-site cultural centres’ role in forming destination cultural attributes, and of social media’s potential in enriching cultural experience. Full article

Urban growth has been fast for decades. Because money is very important in this urban-based world, humanity focuses on economic development, and is often too busy to deal with sustainability. Therefore, in a world that is constantly changing, creating sustainable cities that contain a diverse range of habitats supporting plant establishment is essential. Some surprising urban habitats in which plants can grow, such as cracks on pavements and walls, rocky areas, abandoned places and roofs might be extremely important for sustainability, while urban spaces are under artificial pressure. In this study, which suggesting a method to create more sustainable green roofs for urban areas, and considering roof vegetation is already important for supporting the ecology of urban areas, we surveyed 37 roofs in an urban part of Trabzon city focusing on the habitat effect. We found 51 plant species growing on these 37 roofs, and determined five different roof vegetation typologies in the research area. The main goal in any artificial green roof is to cover roof surfaces with vegetation, and success is considered a perfect coverage rate. We found roof surface size, species richness, size of the sunlit part, daily sunlight duration, and depth of the substrate are the most effective habitat attributes on vegetation coverage on rooftops in the research area.

In the last decade, environment protection gained much more significance in designing the economic policies in the European Union (EU) countries. There are many economic and policy differences between the European countries, despite of the harmonization process inside the EU area. The path of implementation of the environmental tax reforms in the EU countries differs greatly from one country to another and the effects of such taxation in the economic and environmental areas are manifold. The authors of this paper have agreed to undertake the task of testing the double dividend hypothesis of the environmental taxation in Romania (an energy-intensive country) versus the EU area as a whole, using Vector Error Correction Model (VECM) techniques and Ordinary Least Squares (OLS) estimations. Our findings show that this hypothesis is validated neither in Romania (in the economic growth area) nor in the EU area as a whole (in the unemployment area). Therefore, Romania cannot increase the level of the environmental tax for supporting economic growth, but it can grant environmental subsidies for decreasing the emissions and supporting the economic growth. This could be achieved by expanding the tax labor base and by collecting higher budgetary revenues to sustain such environmental subsidies. As far as the EU area is concerned, it is a necessary measure to continue the descending trend for the labor taxation to achieve the goal of improving the employment rate. Full article

The path to sustainable development involves creating coherence and synergies in the complex relationships between economic and ecological systems. In sustaining their farm businesses farmers’ differing values influence their decisions about agroecosystem management, leading them to adopt diverging farming practices. This study explores the values of dairy and beef cattle farmers, the assumptions that underpin them, and the various ways that these lead farmers to combine food production with the provision of other ecosystem services, such as landscape conservation and biodiversity preservation. This paper draws on empirical research from Galicia (Spain), a marginal and mountainous European region whose livestock production system has undergone modernization in recent decades, exposing strategic economic, social and ecological vulnerabilities. It applies a Q-methodology to develop a values-based approach to farming. Based on a sample of 24 livestock farmers, whose practices promote landscape conservation and/or biodiversity preservation, the Q-methodology allowed us to identify four ‘farming styles’. Further analysis of the practices of the farmers in these groups, based on additional farm data and interview material, suggests that all 24 farmers valorize landscape and nature and consider cattle production and nature conservation to be compatible within their own farm practices. However, the groups differed in the extent to which they have developed synergies between livestock farming and landscape conservation. We conclude by discussing how rural development policy in Galicia could strengthen such practices by providing incentives to farmers and institutionally embedding a shift towards more diversified farming and product development.

Given the importance tourism has in many economies, this research was designed to study how the social and environmental benefits of Location Based Services (LBS) in the tourism sector influence user behavior and thus contribute to sustainable development. The objective has been to study LBS as a solution that makes the deployment of tourism activities easier, more useful and improves attitudes towards it, but in a context where trust in privacy and benefits-based sustainable social and environmental development are key. To achieve this, this research identifies what could be the influence factors in the adoption of mobile applications with Location Based Services from the point of view of the tourism sector, especially if the social and environmental benefits of LBS can help improve usage behavior. We investigated the technological acceptance of LBS in tourism, using Technology Acceptance Model (TAM) as a solid model to explain its adoption. Nine hypotheses were investigated by carrying out a survey of travelers (n = 277) during their visit to Seville (Spain). To test the conceptual model’s hypotheses, the Partial Least Squares (PLS) technique was applied to estimate variance-based structural equations models (SEM).The results of this study indicated that tourists are willing to accept these LBS services within a particular adoption model, where trust in privacy and social and environmental benefits are paramount.

This study looks into the factual link between nitrogen fertilizer use and the land annual mean temperature anomalies arising from climate change, incorporating the effect of income and agriculture share to understand better their impact on emissions from agricultural activities along climate indicators. The study unearths causalities associated with this link by employing the Vector Error Correction Model (VECM) with back-dated actual panel data specifically constructed for this study by combining four datasets from 2002 to 2010. In the long-run, the causality is significant and unidirectional, indicating that income, agriculture share, and land temperature anomalies cause agricultural emissions, and that disequilibrium from such emissions is not eliminated within a year. In the short-run, the effective use of nitrogen fertilizers and other associated agricultural practices can be achieved as countries approach per capita income of 7000 USD. Changes in the structure of economies have an expected effect on agricultural emissions. Temperature anomalies increase agricultural emissions from nitrogen fertilizers, possibly due to the fact that the potential negative impacts of these anomalies are mitigated by farmers through changes in crop production inputs. Therefore, as part of adoption strategies, to avoid the excessive and inefficient use of nitrogen fertilizers by farmers, economic incentives should be aligned with the national and global incentives of sustainability.

Forecasting the hourly spot price of day-ahead and intraday markets is particularly challenging in electric power systems characterized by high installed capacity of renewable energy technologies. In particular, periods with low and high price levels are difficult to predict due to a limited number of representative cases in the historical dataset, which leads to forecast bias problems and wide forecast intervals. Moreover, these markets also require the inclusion of multiple explanatory variables, which increases the complexity of the model without guaranteeing a forecasting skill improvement. This paper explores information from daily futures contract trading and forecast of the daily average spot price to correct point and probabilistic forecasting bias. It also shows that an adequate choice of explanatory variables and use of simple models like linear quantile regression can lead to highly accurate spot price point and probabilistic forecasts. In terms of point forecast, the mean absolute error was 3.03 €/MWh for day-ahead market and a maximum value of 2.53 €/MWh was obtained for intraday session 6. The probabilistic forecast results show sharp forecast intervals and deviations from perfect calibration below 7% for all market sessions. Full article

This paper examines how a national risk register supports the implementation of disaster risk management practices at a local level. We present a case study of the UK’s National Risk Register of Civil Emergencies and explore stakeholder understanding, views, perceptions, opinions, and application within the East of England. A semi-structured interview methodology was adopted for this paper with 14 key stakeholders from across the East of England interviewed. Thematic coding analysis was used to structure the results against a set of research questions. Interviewees were found to be largely unaware of the National Risk Register, and as such its usefulness as a risk management tool is limited. In particular, restricted local resources, limited understanding of risk, and a lack of actionable strategies were highlighted as barriers to action. Opportunities for capacity building at the local level, sharing best practice, and improved risk communication were all identified. The National Risk Register could be used to improve risk management at local levels but more engagement with it at a local level is required. Full article

In recent years, there has been a noticeable increase in scholarly interest in corporate social responsibility and its impact on employee attitudes. We intend to add to this literature by introducing unique explanatory and contextual variables. The study explains the impact of Corporate Social Responsibility (CSR) on employee attitudes through justice within the context of cooperative employee relations. We argue that the concept of justice, which is implied in both socially responsible organizational policies and cooperative employee-employer relations, may be an important addition as a mediating variable. In essence, the study explores the mediating effects of the two primary types of justice, i.e., distributive and procedural, on the relationship between perceived corporate social responsibility, and job satisfaction, and affective commitment. Additionally, we introduce ethics-based psychological foundations, i.e., heuristic and deontic fairness theories to explain the studied relationship. The study also examines the moderated mediation effects of the cooperative industrial relations climate on perceived corporate social responsibility and justice perceptions. Our analysis supports the mediating role of both distributive and procedural justice perceptions. However, a moderated mediation role of the industrial relations climate was only found in the relationship between perceived corporate social responsibility, procedural justice, and employee attitudes. Implications of the study are discussed. Full article

Polymer-clay composites were prepared by natural zeolite (clinoptilolite) or naturally local clay deposits in an N,N-methylene-bis-acrylamide as cross-linked. The resultant composites were used for the removal of Cr(VI) from an aqueous solution. Additionally, their effects on soluble ions of tannery wastewater were investigated. The produced composites were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). The results showed that Cr(VI) removal is dependent upon initial concentrations and pH. The adsorption quantity of Cr(VI) onto the polymerized clay deposit followed by polymerized zeolite exhibited higher values than their original samples. The polymer-clay composite of clay deposit showed the highest removal of 76.3–100% overall initial concentrations of 10–50 mg L−1 and at initial pH of 2. Kinetics of Cr(VI) removal by various sorbents was predicted using a pseudo–second order model. Our findings showed that the levels of salinity and various soluble ions (Cr2+, Na+, Cl and SO42−) in tannery wastewater are very high, and their levels were reduced after treatment, especially by polymerized sorbents. It could be concluded that the polymer-clay composites may be employed as a highly efficient sorbent for the removal of Cr(VI) and toxic ions from the wastewater. Full article

Product recycling has become a mandatory activity under extended producer responsibility. Therefore, it is important to operate a closed-loop supply chain that integrates sourcing, production, delivery, and recycling to achieve not only environmental sustainability, but also economic benefits. However, this goal is affected by chronic problems caused by uncertainties relating to the return timing, quantity, and quality of returned items. Many studies proved that information visibility could solve these problems. In this context, a system framework for closed-loop supply chain management is proposed that gathers real-time information within a supply chain and product lifecycle by using the Internet-of-Things, including radio frequency identification (RFID). Specifically, the most recent Gen2 RFID protocol, which provides new features to create new positive effects, is considered. Additionally, an information system is designed, including RFID tag encoding, which supports the operation of the proposed system. Finally, the lifecycle benefits are examined, such as counterfeit prevention, real-time monitoring and maintenance in the middle-of-life phase, and reverse process streamlining. The ultimate aim is to design a system that facilitates the profitable and environmentally friendly operation of the closed-loop supply chain. Full article

Rapid tourism development adversely impacts and negatively transforms World Heritage Sites. This study aimed at examining how tourism growth has impacted the built environment of Luang Prabang, Lao PDR through an empirical approach. Luang Prabang has received a critical warning from World Heritage Committee for the escalating development pressure on its vulnerable landscape. Hence, this study examined two aspects: (1) the spatial pattern of the increase of touristic usage; and (2) the relation between the increase of touristic usage and the significant changes in the built environment. For this, geographical information systems (GIS) are combined with statistical methods such as logistic regression and chi-square test of independence. The results affirmed that the change from other types of usage to touristic usage in existing buildings has a higher chance to occur along riverbank areas than in the middle of the peninsula in the core heritage area. Change to touristic usage is also related with three significant changes in the built environment, namely: (1) change from other types of architecture to Lao traditional architecture; (2) change from modern to traditional roof materials; and (3) change from traditional to modern building materials. This indicates that the increase in touristic usage has contributed to strengthening the heritage elements of the landscape. Full article

Precision viticulture is the application of site-specific techniques to vineyard production to improve grape quality and yield and minimize the negative effects on the environment. While there are various studies on the inherent spatial and temporal variability of vineyards, the assessment of the environmental impact of variable rate applications has attracted limited attention. In this study, two vineyards planted with different grapevine cultivars (Sauvignon Blanc and Syrah) were examined for four consecutive growing seasons (2013–2016). The first year, the two vineyards were only studied in terms of soil properties and crop characteristics, which resulted in the delineation of two distinct management zones for each field. For the following three years, variable rate nutrient application was applied to each management zone based on leaf canopy reflectance, where variable rate irrigation was based on soil moisture sensors, meteorological data, evapotranspiration calculation, and leaf canopy reflectance. Life cycle assessment was carried out to identify the effect of variable rate applications on vineyard agro-ecosystems. The results of variable rate nutrients and water application in the selected management zones as an average value of three growing seasons were compared to the conventional practice. It was found that the reduction of product carbon footprint (PCF) of grapes in Sauvignon Blanc between the two periods was 25% in total. Fertilizer production and distribution (direct) and application (indirect) was the most important sector of greenhouse gas (GHG) emissions reduction, accounting for 17.2%, and the within-farm energy use was the second ranked sector with 8.8% (crop residue management increase GHG emissions by 1.1%, while 0.1% GHG reduction is obtained by pesticide use). For the Syrah vineyard, where the production was less intensive, precision viticulture led to a PCF reduction of 28.3% compared to conventional production. Fertilizers contributed to this decrease by 27.6%, while within-farm energy use had an impact of 2.2% that was positive even though irrigation was increased, due to yield rise. Our results suggest that nutrient status management offers the greatest potential for reducing GHG emissions in both vineyard types. Variable rate irrigation also showed differences in comparison to conventional treatment, but to a lesser degree than variable rate fertilization. This difference between conventional practices and precision viticulture is noteworthy, and shows the potential of precision techniques to reduce the effect of viticulture on GHG emissions.

Climate change and associated uncertainties have serious direct and indirect consequences for crop production and food security in agriculture-based developing regions. Long-term climate data analysis can identify climate risks and anticipate new ones for planning appropriate adaptation and mitigation options. The aim of this study was to identify near-term (2030) and mid-term (2050) climate risks and/or opportunities in the state of Bihar, one of India’s most populous and poorest states, using weather data for 30 years (1980–2009) as a baseline. Rainfall, maximum and minimum temperatures, and evapotranspiration will all increase in the near- and mid-term periods relative to the baseline period, with the magnitude of the change varying with time, season and location within the state. Bihar’s major climate risks for crop production will be heat stress due to increasing minimum temperatures in the rabi (winter) season and high minimum and maximum temperatures in the spring season; and intense rainfall and longer dry spells in the kharif (monsoon) season. The increase in annual and seasonal rainfall amounts, and extended crop growing period in the kharif season generally provide opportunities; but increasing temperature across the state will have considerable negative consequences on (staple) crops by affecting crop phenology, physiology and plant-water relations. The study helps develop site-specific adaptation and mitigation options that minimize the negative effects of climate change while maximizing the opportunities. Full article

The main purpose of this study was to determine the structure of consumer preferences regarding information on farming system and nutritional enhancement of eggs to verify if consumers are willing to accept products combing sustainability and nutrition related claims. The data was collected within a CAPI (Computer Assisted Personal Interviews) survey on a representative sample of 935 consumers responsible for food shopping. A discrete choice-based conjoint method was selected in eliciting consumer preferences among different product profiles with varying levels of attributes. A hierarchical cluster analysis was used to identify four distinct clusters that differed significantly in terms of importance attached to production system attributes and socio-demographic profiles. The results of the experiment showed that price and farming system had the most significant mean relative importance in shaping consumers’ preferences, while other attributes such as nutrition and health claims, egg size, package size and hen breed were far less important. Free range eggs had the highest relative importance for consumers despite the fact that organic egg production systems are governed by much stricter animal welfare standards. Our segmentation revealed that two of our four clusters may be more easily reached by information on animal welfare related attributes in egg production than the others. The results of our study provide the policy makers and marketing practitioners with insights applicable for communication and pricing strategies for eggs with sustainability claims. Full article

This regional case study is focused on employment, remuneration and labor productivity, with a particular emphasis on the interplay between labor productivity and other labor-related indicators and macroeconomic conditions in Italy, Egypt, Lebanon and Greece. Its value lies in the high degree of consistency and comparability of the data, owing to a shared data collection methodology. This has allowed for the compilation of both national and regional comparisons. The data is treated in two groups—the first group consists of national data that considers all the active vessels in a country; the second group focuses on the trawl segments of Italy and Egypt. These two countries present an interesting case study because they are so different in terms of labor productivity and remuneration performance. For instance, in Italy labor shortages have caused a shift in fishing strategies towards less labor-intensive operations to maintain the socioeconomic sustainability of the fisheries, while in Egypt macroeconomic conditions have resulted in a larger labor pool and strong incentives to work in the fisheries sector. The regional study demonstrates that labor-related indicators are interconnected and there is an inversely proportional relationship between labor productivity and remuneration and employment levels. This relationship necessitates a combined analysis. The results across and between the countries were compared, with particular attention given to labor productivity and remuneration in the respective countries with a discussion centred around the potential drivers of labor productivity.

We examine the fundamental tension between explicit and implicit power motives; and their combined impact on the importance attached to prosocial organizational goals in small businesses (SMEs). We show that key decision-makers with a dominant implicit power motive attach more importance to the prosocial goals of job creation and taking care of the environment in their businesses. However, we reveal that this positive relationship is moderated by their explicit power motive. Once decision-makers in SMEs consciously seek for power, the positive relationship is neutralized. With these results, we highlight the conceptual and methodological differences between implicit and explicit power motives. We could obtain these results because we developed and validated an innovative implicit motive measure—the Shortened Pictorial Attitude Implicit Association Test (SPA-IAT). Contrary to the currently available implicit motive measures, the SPA-IAT is fast and easy to use and analyze, which makes this novel instrument well suited for research in business settings.

Stone surfaces and façades of historic buildings, due to their predominately outdoor location, suffer from many deterioration factors, including air pollution, soluble salts, relative humidity (RH)/temperature, and biodeterioration, which are the main causes of decay. In particular, the façades of the buildings deteriorate with direct exposure to these factors; deformation and disfiguration of superficial decoration and formation of black crusts are often observed on the stones. The development and application of self-cleaning and protection treatments on historical and architectural stone surfaces could be a significant improvement in the conservation, protection and maintenance of Cultural Heritage. A titanium dioxide nanoparticle has become a promising photocatalytic material, owing to its ability to catalyze the complete degradation of many organic contaminants and environmental factors. In this study, TiO2 nanoparticles, dispersed in an aqueous colloidal suspension, were applied directly to historic marble stone surfaces, by spray-coating, in order to obtain a nanometric film over the stone surface. The study started with an investigation of some properties of TiO2 nanoparticles, to assess the feasibility of the use of TiO2 on historic stone and architectural surfaces. Scanning electron microscopy (SEM) was, coupled with energy dispersive X-ray (EDX) microanalysis, (SEM-EDX), in order to obtain information on coating homogeneity and surface morphology, before and after artificial aging; the activity of the coated surface was evaluated through UV-light exposure, to evaluate photo-induced effects. The changes of molecular structure occurring in treated samples were spectroscopically studied by attenuated total reflection infrared spectroscopy (ATR-FTIR); activity of the hydrophobic property of the coated surface was evaluated by Sterio microscopy, model Zeiss 2010 from Munich, Germany, equipped with photo camera S23 under 80X magnification. The efficacy of the treatments was evaluated through capillary water absorption, and colorimetric measurements, performed to evaluate the optical appearance. Results showed that TiO2 nanoparticles are good candidates for coating applications on historic stone surfaces, where self-cleaning photo-induced effects are well evident; they enhanced the durability of stone surfaces toward UV aging, improved resistance to relative humidity (RH)/temperature and abrasion affect, reduced accumulation of dirt on stone surfaces when left in open air for 6 months, and did not alter the original features.

Research on food planning has been recently proposed in North American and European planning to account for how cities might change their food provision to respond to the rising demands for a more sustainable and ethical food system. The purpose of this paper was to evaluate the agro-ecological potential of the Lisbon city region, Ribatejo e Oeste, to increase its Regional Food Self-Reliance (RFSR), through adopting demand restraint and food system relocalization approaches to food system sustainability. Three new diet scenarios were considered: meat-based, plant-based and strict vegetarian, defined in accordance with healthy dietary patterns. We used agro-climatic and agro-edaphic agricultural suitability models to evaluate the agro-ecological potential for RFSR, and proposed the use of Foodshed Landscape Plans within a landscape planning methodology. Results showed the extent of local food production that could improve food self-reliance, with 72%, 76%, 84% of total food needs in the meat-based, plant-based, and strict vegetarian scenarios, respectively. Thus, food system transformation by means of relocalization, is therefore ecologically feasible and would ensure the sustainable use of the ecological basis of food security. Additionally, a dietary transition would imply significant land sparing, which strengthens the demand restraint perspective for a transition to food system sustainability. Full article
