Ecosystem services are highly affected by human activities, especially in the fast-urbanizing regions. It is important that the regional development or urbanization strategy be implemented by maintaining or protecting the long-term provision ability of multiple ecosystem services. The spatial pattern of ecosystem services and zoning for spatial conservation and restoration are the preconditions of sustainable development. With the Beijing-Tianjin-Hebei (BTH) region as the research area, an approach for spatial zoning was proposed on the basis of the modeling results of key ecosystem services (water retention, soil retention, heat mitigation, and carbon storage). Our results show that the hot spots of ecosystem services are mainly in the north and the west at high altitudes and with large vegetation coverage, while the cold spots are mainly in the plain area of the southeast in the BTH region. In addition, the whole region is divided into five ecological zones: the ecological restoration zone, ecological transition zone, coastal ecological protection zone, soil and water retention zone, and ecological security shelter. Each zone has applied different strategies for ecological restoration and conservation. The results represent the spatial heterogeneity and major functions in different zones, and they can provide planning guidance for supporting the coordinated development of the BTH region.

A small amount of campus walkability research has considered facility layout and environmental quality. The aim of this paper is to use a Walk Score and Urban Design Quality to assess campus walkability and investigate the impact of a campus Walk Score, environmental quality and other streetscape features on walking activity. This paper optimizes the Walk Score method based on the frequency, variety, and distance of students’ walking to and from public facilities. A total of 157 campus street segments from the Weijin Road Campus of Tianjin University in China were selected to assess campus Walk Scores and environmental quality through the use of GIS and field audits. The effect of campus walkability and environmental features on pedestrian volume was examined by negative binomial regression. We found that Walk Score, transparency, street furniture, the number of buildings and noise level have a positive effect on walking activity, while enclosure and building basic color show a negative relationship with pedestrian volume. The results will be used to propose strategies to improve campus walkability and promote walking activity. Full article

The relationship between government intervention and cooperative development has always been a source of controversy in the developing world. This paper aims to examine the rationale and successful conditions of government intervention to promote cooperative development in poor areas of rural China. In the context of the “targeted poverty alleviation” program (2015–2020), a government-led campaign covering all poverty-stricken villages in west China, cooperative development was listed by the central government as a criterion for evaluating successful intervention at the county government level. Accordingly, the central questions of this paper are: why is government intervention necessary to initiate a process of cooperative development in poor areas of China; and under what conditions can government intervention be successful, leading to sustainable cooperative development? Bearing in mind the complexity of government intervention with mixed results, both successful and failed, the above questions are addressed through a case study of XM Beekeeping Cooperative, representing one type of successful government intervention in poverty-stricken and ethnic-minority-dominated regions of China. Overall, government intervention is crucial in building cooperative ecosystems in poor regions of China. However, government intervention is not invariable because the approaches can be modified to accommodate the effect of the intervention. Full article

Ecological restoration is an important implement to avoid land degradation and improve the sustainability of ecosystems. As a spatial definition of ecological restoration, ecological restoration space (ERS) is recognized to have a positive impact on the environment. However, its spatiotemporal pattern and magnitude of contribution to ecosystem services (ESs) remain uncertain. In this study, an ecological restoration trajectories model was developed to investigate the spatiotemporal pattern and evolution of ERS. The InVEST model and geographically weighted regression were used to evaluate the dynamic relationship between ERS and crucial ESs. Results demonstrated that from 1990 to 2015, the cumulative area of ERS in the Yellow River Basin (YRB) was 184,197.05 km², with Inner Mongolia, Qinghai, and Shaanxi having the largest distribution. The change in geographical center of three subcategories, forest restoration space (FRS), grassland restoration space (GRS), and shrub restoration space (SRS), showed a pronounced geographical migration. Meanwhile, the distribution of ERS significantly improved the conditions of habitat quality (HQ), carbon storage (CS), and soil conservation (SC) on 75.48%, 71.86%, and 56.75% of the grids, respectively. This study provides a scientific foundation for the ecosystem conservation and land management of the YRB. Full article

Landscapes are important socio-ecological systems. They are widely researched through landscape ecology to aid conservation and environmental management efforts, yet these efforts are not always as successful as they could be in terms of on-the-ground impact. Increasingly when considering conservation, it is being recognized that indigenously managed landscapes have slower rates of biodiversity loss and better environmental outcomes. Local knowledge and connection to the landscape can play a significant part in successfully managing these landscapes. Acknowledging that stewardship of the landscape is more effective when people are a part of the landscape with deep-rooted connection to place is important for understanding the significance of traditional ecological knowledge and the implementation of indigenous-led action. It has also been shown that researchers who have a stronger sense of place and connection to landscapes can also drive initiatives that have better environmental outcomes. This means that human connections to landscapes are important for management strategies, and a better understanding of the human cognition of landscapes is necessary in landscape ecological theoretical frameworks. This review paper explores literature that acknowledges cultural perspectives and cognition of landscapes and how this relates to landscape ecology. It makes recommendations about how landscape ecology can contribute towards better on-the-ground outcomes by embracing more effective mechanisms of collaboration and participation to incorporate local and indigenous knowledge.

Greenspaces are argued to be one of the important features in the urban environment that impact the health of the population. Previous research suggested either positive, negative, or no associations between greenspaces and health-related outcomes. This paper takes a step backward to, first, explore different quantitative spatial measures of evaluating greenspace exposure, before attempting to investigate the relationship between those measures and health-related outcomes. The study uses self-reported health data from an online cross-sectional survey conducted for residents in the West of England. This yielded data of greenspace use, physical activity, wellbeing (ICECAP-A score), and connectedness to nature for 617 participants, divided into two sets: health outcomes for the period before versus during the 2020 lockdown. The study uses the participants’ postcodes (provided in the survey) to calculate eleven spatial measures of greenspace exposure using the software ArcGIS Pro 2.9.5. A total of 88 multivariate regression models were run while controlling for eleven confounders of the participants’ characteristics. Results inferred 57 significant associations such that six spatial measures of greenspace exposure (NDVI R200m, NDVI R300m, NDVI R500m, Network Distance to nearest greenspace access, Euclidean Distance to nearest greenspace access, and Euclidean Distance to nearest 0.5 ha doorstep greenspace access) have significant association to at least one of the four health-related outcomes, suggesting a positive impact on population health when living in greener areas or being closer to greenspaces. Moreover, there are further significant associations between the frequency of use of greenspaces and increasing physical activity or feeling more connected to nature. Still, the residents’ patterns of using greenspaces significantly changed during versus before lockdown and has impacted the relationships between health outcomes and the greenspace exposure measures.

Urban parks are places that have significant impact on the physical and mental health of citizens, but they are also for safeguarding biodiversity and thus fostering human–nature interactions in the everyday landscape. The exploration of these spaces through social media represents a novel field of research that is contributing to revealing patterns of visitor behavior. However, there is a lack of comparable research from a non-anthropocentric perspective. What if we could use social media as a more-than-human communication medium? This research aims to reveal the possibility of communicating the urban forest’s voice through the examination of the official Twitter account of a metropolitan park in Tokyo. To this end, an analysis of the content of the messages is carried out, focusing on the narrative voice from which the message is told, the protagonists, the action performed, the network of actors deployed, and the place where it occurs. It is found that the majority of these messages are delivered from a non-human perspective, where plants, animals, or meteorological agents behave deploying complex networks of more-than-human interaction. The current study reveals the latent potential of non-humans as possible agents within the realm of social media, which can mediate the relationships between humans and their environment. It introduces a layer that can be incorporated into future lines of research, as well as provides a model case that illustrates a good practice in the management and communication of urban green spaces.

The goal of this paper is to present a methodology for setting priorities among interventions in the old city center of Florence, going from the conservation to the regeneration of its heritage. The proposed methodology is based on specific methods of analysis of degradation and parameters for the optimization of construction costs. The methodology can be considered an additional part of the Management Plan of the site of the Historic Center of Florence (adopted for the first time in 2016 and now updated with the inclusion of a buffer zone) that “represents an important tool for the conservation and enhancement of the Heritage and is also a source of address for the choices that the Administration is called to adopt regarding the use of the city and its spaces”. The application of the method, in addition to being in harmony with some of the action projects of the second macro-area of the new Management Plan, also has points of contact with the provisions of the Municipal Operational Plan that provides for a reinterpretation of the existing building heritage. From the monitoring of individual buildings, aimed at their preservation, we will move to study the relationships that promote the creation of joint construction sites, thus optimizing costs.

(1) Background: the broadcast is an outdated fertilization method with a low fertilizer-utilization rate and environmental problems, which seriously restricts the development of agriculture. (2) Methods: Under a machine-transplanted rice with side-deep fertilization (MRSF) mode, five treatments were applied: 0 cm (D0), 5 cm (D5), 7.5 cm (D7.5), and 10 cm (D10), comprising four different depths of fertilization, and no fertilization (CK). The yield, the accumulation of N and P in the straw and in grains of rice, concentrations of N and P in the surface water, ammonia (NH₃) volatilization, and soil nutrients were measured in rice fields. (3) Results: In rice yields, compared with the D0 treatment, only the D7.5 treatment significantly increased by 7.84% in late rice, while the other treatments showed no significant difference between early and late rice. The N- and P-use efficiency of D10 increased by 5.30–24.73% and 0.84–17.75%, respectively, compared with the D0-D7.5 treatments. In surface water, compared with the D0 treatment, D5, D7.5, and D10, the total N (TN), total P (TP) concentration, and NH₃ volatilization decreased by 10.24–60.76%, 16.30–31.01%, and 34.78–86.08%, respectively; the D10 treatment had the best inhibition effect on the TN, TP concentration, and NH₃ volatilization, which were 58.48–60.76%, 22.04–31.01%, and 77.21–86.08%, respectively. (4) Conclusions: The optimized depth for side-deep fertilization was 10 cm. We would like to emphasize the impact of the paddy on various deep fertilizations and provide an important reference for developing precise fertilization in rice fields in this area. Full article

Over the past two decades, the relative socio-economic importance of land-based sectors has declined in comparison to non-land-based businesses such as tourism, food and beverage activities. However, policy implementation and research have primarily focused on the economic contributions of land-based businesses, leaving businesses outside these sectors and in rural areas, referred to as non-land-based businesses, largely overlooked. Therefore, this study aims to examine the importance of non-land-based businesses and the key determinants of the relationships between non-land-based businesses and land-based (farming, forestry and landed estate) sectors in rural Scotland. Through a survey of 1500 businesses whose primary focus is not agriculture, forestry or landed rural estates in four Scottish regions, the key findings of the logit model reveal that businesses located in rural areas are more likely to have relationships, both direct (supplying or purchasing goods/services) and indirect, with farming, forestry and landed estate sectors than their urban counterparts. Focusing on rural businesses, the results show that business size, sectors, business age, exporting, importing and business constraints related to cash flow, digital connectivity and government financial support significantly influence their relationships with land-based sectors. The results of crosstab analysis also reveal differences in business performance, business challenges related to Brexit and future plans between non-land-based rural businesses having relationships with land-based sectors in different rural classifications: accessible/remote small towns, accessible rural areas and remote rural areas. The paper concludes with policy recommendations to support rural businesses and future land-based and non-land-based sectors in rural Scotland. Full article

Anthropogenic landscape transformations have promoted the provision of ecosystem services (ES) at the expense of other ES, biodiversity, and human well-being. We analysed the transformation portfolios of ES provisions, the costs of transformation, and the rivalry between ES categories and biodiversity conservation during the pre-communist and communist eras. We also examined EU influences in Romania’s Danube River lowlands. The environmental history of social-ecological systems was used to: (1) map transformations of natural environments; (2) analyse the outputs of human modes of production, including crops, fish, timber, and livestock, using economic valuation methods and by appropriating the primary means of production; and (3) describe ideologies and values as drivers of ES transformations. During the communist era, the surface area of the agricultural land increased at the expense of natural ecosystems. This resulted in increased provisions being made for crops and timber at the expense of the fish supply; it also caused a reduction in livestock. The costs of land reclamation, hydrotechnical works, and the use of fertilizers and pesticides, resulted in a net annual loss of EUR 36 million for the entire case study area, disregarding the losses of other ES. Achieving a balanced portfolio of ES requires a discussion about the need for nature restoration, transdisciplinary social-ecological research, and the identification of key leverage points.

Cities in China do not constitute a few global metropolises, but are characterized by heterogeneity. Studying counties can give us a comprehensive picture of urban sprawl in China. This study measured the sprawl index of 1880 counties in China from 2005 to 2020 for the first time and then revealed the evolution of their spatiotemporal characteristics and driving mechanisms. The results revealed the following. (1) China’s counties had a noticeable sprawling trend from 2005 to 2020, and their evolutionary process was characterized by spatiotemporal heterogeneity. (2) From 2005 to 2020, the counties’ sprawl gradually evolved into a spatial distribution pattern of high in the east and low in the west. The spatial distribution of sprawl in county and municipal districts had the characteristics of an interlocking distribution. (3) High–high cluster areas of CSI are mainly distributed in plains, and hilly, basin, and plateau areas tend to be low–low cluster areas. High–low outliers were distributed in a “point–line” pattern along the railroad lines and a cluster pattern near railroad intersections and central cities. Low–high outliers had the trend of encircling the high–high cluster areas. (4) The coefficient of the natural drivers was higher but tended to decrease, while the coefficient of economic and spatial drivers was lower but gradually increased. This study is the first to refine the study of urban sprawl to the county scale, which provides a reference for decision making to optimize the spatial structure of counties and thus promote high-quality development.

Research on carbon emission is an important basis for solving global climate problems, and it is also one of the ways to quantitatively assess the impact of human activities. Cities are one of the main bearing spaces of human activities, and reasonable urban form is conducive to reducing energy consumption in human activities. This paper takes 50 clusters within Zhuhai, China, as the research object, quantifies the landscape spatial form index and social spatial form index of each cluster and establishes the index set of urban spatial form, so as to analyze the influence of different urban spatial form index on carbon emission. The main conclusions are as follows: (1) From the spatial distribution of each index, the urban cluster size and residential building area of each cluster in Zhuhai are generally large, and the distribution is basically consistent with that of densely populated areas. The urban clusters with high dominance are mainly located in the main urban area of Xiangzhou District, and the urban compactness, dispersion and industrial building area are generally high in the west and low in the east. (2) The size of urban clusters, industrial building area and residential building area have a strong promoting effect on carbon emission, while the compactness, dispersion and dominance of urban clusters have a strong inhibiting effect on carbon emission. (3) Based on the above conclusions, the low-carbon urban spatial form optimization strategy should be proposed from three aspects: urban development boundary control, promoting industrial structure transformation and compact urban development.

With in-depth efforts in the national strategy of innovation-driven development, the demand for talent in cities is burgeoning. Cities in China have released a large number of preferential policies to attract talent as these cities look to gain an edge in increasing talent competition. This study empirically studied the effect of talent competition on urban innovation using a panel data set of 298 prefectural-level cities in China from 2010 to 2019 based on the difference-in-difference model and an event study method. The results show that there are heterogeneous effects of talent competitions on urban innovation, which may widen the gap between urban innovation in different cities. The effect of talent competition in different cities showed a significant positive correlation with the level of urban development, and there is a “head effect” of talent competition on urban innovation. Moreover, the results of the mechanism analysis indicate that the effect of talent competition on urban innovation is mainly through talent flow. These findings can help policymakers formulate scientific and reasonable talent policies to promote the strategy of innovation-driven development. Full article

Due to the heterogeneity among households across locations, predicting the impacts of stay-at-home mitigation and lockdown strategies for COVID-19 control is crucial. In this study, we quantitatively assessed the effects of the Namibia government’s lockdown control measures on food insecurity in urban informal settlements with a focus on Windhoek, Namibia. We developed three types of conditional regression models to predict food insecurity prevalence (FIP) scenarios incorporating household frequency of food purchase (FFP) as the impacting factor, based on the Hungry Cities Food Matrix. Empirical data were derived from the 2017 African Food Security Urban Network (AFSUN) Windhoek study and applied univariate probit and bivariate partial observability models to postulate the relation between food insecurity and FFP within the context of stay-at-home disease mitigation strategy. The findings showed that FFP was positively correlated with the prevalence of food insecurity (r = 0.057, 95% CI: 0.0394, 0.085). Daily purchases portrayed a survivalist behaviour and were associated with increased food insecurity (coeff = 0.076, p = 0.05). Only those who were purchasing food twice monthly were significantly associated with reduced food insecurity (coeff = −0.201, p = 0.001). Those households in informal settlements were severely impacted by food insecurity (coeff = 0.909, p-value = 0.007). We conclude that public health compliance should precede with cash or food support to poor households in balance with the need for long-term placement of control measures to fully contain COVID-19 or related infectious diseases.

The general consensus is that physical activity can prevent and manage lifestyle-induced chronic diseases, and moderate-to-vigorous physical activity (MVPA) has been included in several guidelines of WHO as an indicative intensity standard. Numerous studies have confirmed that improving the spatial quality of urban parks can be very helpful in supporting physical activities, and that the quality of parks is significantly related to the intensity of physical activities. However, few studies have explored the spatial characteristics of activating physical activities. Using a modified System for Observing Play and Recreation in Communities (SOPARC), this study examines the relationship between spatial characteristics and MVPA through a binary logistic regression model. The results reveal that: firstly, inconsistent with other similar studies, the most observed group in the park is the adults rather than the seniors, and the proportion of the females (51%) is higher; secondly, the distribution of MVPA in different groups shows that the seniors have less interaction with other groups, and they have a significant spatial attachment. Thirdly, in functionality, large lawn and jogging trails have been proved to be the most effective features to promote the occurrence of MVPA; among the activity, except for the significant correlation between equipped and MVPA, other attributes can be proved to encourage MVPA as well as those in comfort. In conclusion, our results can contribute to the planning and design of the urban park as well as the further management and allocation of the space and facilities under the vision of promoting public health.

Agricultural terraces provide farmers in hilly landscapes with effective ways to increase the area available for crops. They mitigate the risks of soil erosion and promote crop productivity by slowing surface water runoff and retaining moisture. As in other parts of the world, terraces have been constructed and used in the Mediterranean for millennia. The availability of terraced agriculture had important socio-economic, ecological, and environmental implications for past societies. However, the chronology of construction, use, and abandonment of terraces in different regions remains uncertain. A more robust set of chronological data will allow better assessment of whether terrace agriculture was a resilient strategy in the face of past economic or ecological instability and, in turn, inform how terraces could be used to address future agricultural and environmental challenges. In this paper, we review the application of luminescence dating to terrace sediments, the key challenges involved, and the currently published data which include over 250 luminescence ages. We also discuss the use of a multidisciplinary approach involving other geoarchaeological tools (e.g., use of GIS analyses, field-based luminescence readers, and micromorphology) to enhance the ways that past terrace systems can be understood. Terrace systems are inextricably linked to sustainable land use across the Mediterranean. Luminescence dating methods, therefore, have a crucial role to play in understanding the complexities of past and future landscape change. Full article

In this study, we estimated the magnitude of soil-to-atmosphere carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) fluxes in deciduous tree and willow coppice based agroforestry systems in hemiboreal Latvia. We studied systems combining hybrid alder, hybrid aspen, silver birch, black alder, and willow clones with perennial reed canary grass (RCG), which were established in the spring of 2011 in former cropland with mineral soil. Three different soil fertilisation practices were initially applied (control without fertilisation, fertilisation with wood ash, and sewage sludge). Measurements of fluxes of greenhouse gases were taken in both deciduous tree, willow coppice and RCG plots using a closed opaque manual chamber method, from June 2020 to October 2021. Soil CO₂ fluxes (the sum of autotrophic and heterotrophic respiration) were increased in RCG plots compared to plots under willow and deciduous tree canopies, while the highest mean CH₄ fluxes were found in willow coppice plots. No impact of dominant vegetation type on instantaneous soil N₂O fluxes was found. Temperature was the key determinant of the magnitude of CO₂ and N₂O fluxes. The highest soil CO₂ and N₂O fluxes were detected during the summer and decreased in the following order: summer, autumn, spring, winter. There were no pronounced relationships between soil CH₄ fluxes and temperature. Full article
