This article examines the struggles for water justice led by women in the Aconcagua River Basin (Valparaíso, Chile) through a hydrofeminist perspective. Chile’s water crisis, rooted in a colonial extractivist model and exacerbated by neoliberal policies of water privatization, reflects a deeper crisis of socio-environmental injustice. Rather than understanding water merely as a resource, this research adopts a relational epistemology that conceives water as a living entity shaped by and shaping social, cultural, and ecological relations. Drawing on life-history interviews and the construction of a hydrofeminist cartography with women river defenders, this article explores how gendered and racialized bodies experience the crisis, resist extractive practices, and articulate alternative modes of co-existence with water. The hydrofeminist framework offers critical insights into the intersections of capitalism, colonialism, patriarchy, and environmental degradation, emphasizing how women’s embodied experiences are central to envisioning new water governance paradigms. This study reveals how women’s affective, spiritual, and territorial ties to water foster strategies of resilience, recovery, and re-existence that challenge the dominant extractivist logics. By centering these hydrofeminist life histories, this article contributes to broader debates on environmental justice, decolonial feminisms, and the urgent need to rethink human–water relationships within the current climate crisis.

African cities are experiencing rapid, unregulated growth, characterized by high land pressure and growing demand for housing and urban infrastructure. New arrivals often settle in vulnerable areas (wetlands, hills, flood) where land is cheaper and unregulated by public authorities. This type of settlement is accompanied by numerous land conflicts, exacerbated by the coexistence of formal and customary land tenure systems, which struggle to harmonize. In this context, public land regulation policies often remain centralized and ill-adapted, revealing their limitations in ensuring equitable and sustainable management of urban land. Faced with this gap, our systematic study explores the socio-environmental dynamics of this normative pluralism in land governance within Cameroonian cities. Our findings highlight the tensions and opportunities of this complex coexistence, which vary significantly according to city size (small, medium, and large), the colonial heritage (Francophone and Anglophone), and the dominant legal framework (civil law and common law). The analysis highlights the need to take into account historical, linguistic, and politico-administrative roots, which profoundly influence local forms of the institutionalization of normative pluralism and the associated socio-environmental vulnerabilities. This normative plurality underlines the importance of a hybrid system of land governance capable of integrating local specificities while ensuring land security for all. Future research will include comparisons with other African countries in order to understand transferable mechanisms for better land governance. Full article

Urban parks are essential for enhancing public health and environmental sustainability, as they reduce urban heat, improve air quality, and provide spaces for physical activity. Inequalities in park allocation, however, lead to access discrepancies, disproportionately impacting populations already struggling socially. The spatial disparity between park supply and demand in Busan, South Korea, is examined in this study through a quantitative approach incorporating socio-economic indicators and GIS(Geographic Information System)-based analysis. First, we divided Busan into 100 m × 100 m grid cells and applied a modified Huff model, setting a kind of distance-decay exponent β, to estimate park supply against baseline demand (the planning standard of 6 m² per person), and overlaid a composite need index of six socio-economic indicators to pinpoint underserved areas. Our first stage grid-based arithmetic analysis revealed that 100 of Busan’s 205 communities are undersupplied. Given a composite need index of six socio-economic indicators, sixty-two cells remained imbalanced, and we finally identified the ten communities with the highest need for targeted park provision. The findings indicate that Busan’s park planning policies, aimed at enhancing per capita green space, do not adequately address localized disparities. Accordingly, as opposed to a uniform expansion plan, this study stresses the importance of prioritizing park provision according to community-specific needs. These results suggest that policymakers could enhance public health outcomes and advance social equity by considering socio-economic vulnerabilities when planning cities. Specifically, this research highlights the significance of including environmental justice in urban sustainability frameworks and gives actionable ideas for fair park allocation. Full article

The rapid pace of urbanization has led to excessive resource consumption and worsening environmental pollution, particularly in resource-based cities, where prolonged exploitation of mineral resources has resulted in dual challenges of ecological degradation and economic imbalance. Using Fushun, a resource-exhausted city still struggling with its transformation, as a case study, this research develops a progressive analytical framework that integrates the InVEST model, optimal parameter geographic detector, and multi-scale geographically weighted regression. This framework, comprising a sequence of analytical steps—single-factor analysis, interaction-factor analysis, global regression analysis, and geographically weighted regression analysis—enables a comprehensive exploration of the driving mechanisms behind ES changes in Fushun from 2000 to 2020. The results indicate the following: (1) Significant changes in ecosystem services were observed, with water yield and soil conservation showing a fluctuating upward trend, while carbon storage and habitat quality experienced slight declines. (2) Over time, the dominant drivers transitioned from primarily socio-economic factors to a synergistic influence of natural and human activities. GDP and land use intensity increasingly contributed to explaining ecosystem services through their interaction effects. (3) At the street scale, driving mechanisms exhibited spatial heterogeneity. For instance, the negative effects of built-up land and cultivated land were more pronounced in urban–rural transition zones, while elevation and NDVI had a more positive impact in ecological source areas. This framework provides systematic and targeted recommendations that offer data-driven insights to guide policies prioritizing regional ecological sustainability. Furthermore, it provides practical reference points for improving the ecological quality of other coal resource-exhausted cities undergoing incomplete transformations. Full article

Progressing soil degradation worldwide is a complex socio-environmental threat. Implementing environmental policies and actions such as the Sustainable Development Goals, the European Green Deal, and the Renewable Energy Directive III regarding environmental protection aims to protect, conserve, and enhance the EU’s natural capital, focusing on soil protection. As assumed in the Green Deal, the European economy has to be turned into a resource-efficient and green economy with zero net emission of greenhouse gases. Since soil quality strongly influences all ecosystem elements, soil remediation is increasingly promoted as a sustainable option to enhance soil quality and, at the same time, help achieve overarching goals set out in European climate law. Biomass in phytoremediation is particularly important in regenerative agriculture, as it emphasizes improving soil quality, increasing biodiversity, and sequestering carbon. Selected plants and microbes can clean degraded agricultural areas, removing heavy metals and pesticides, thus lowering soil toxicity and improving food and feed security. Moreover, the post-phytoremediation biomass can be processed into biofuels or bioproducts, supporting the circular economy. This article summarizes the role of plants and microbial biomass in the struggle to achieve EU environmental goals, enabling the regeneration of degraded ecosystems while supporting sustainable development in agriculture.

The adoption of biopesticides in Mediterranean agriculture is shaped by environmental, economic, and socio-cultural factors. This study explores the push and pull factors influencing farmers’ decisions in Spain’s Ebro Delta, Tunisia’s Nabeul region, and Turkey’s Adana province. Through qualitative fieldwork and comparative analysis, key barriers to adoption are identified, including high costs, limited market availability, skepticism about efficacy, and reliance on conventional pesticides. However, this study also highlights opportunities driven by regulatory changes, increasing market demand for sustainable products, and the potential of biopesticides to improve ecological sustainability. The research follows a comparative case-study approach and was conducted between January and November 2024. The methodology included a literature review, two rounds of qualitative interviews with farmers, and thematic analysis to identify barriers and enabling factors, ensuring methodological rigor and cross-validation. Findings indicate that farmers’ professional ethos and economic conditions significantly limit biopesticide adoption. Perceived inefficacy, high production costs, and low profit margins reinforce reluctance. Spain struggles with skepticism, Tunisia faces economic and informational barriers, and Turkey’s reliance on traditional practices slows innovation. Despite these obstacles, key drivers facilitate adoption, including improved agricultural education, cooperative support, and increasing consumer demand for sustainable products. Legal frameworks, particularly the EU’s “Farm to Fork” strategy, play a crucial role, though top-down policies risk local resistance. This study outlines a model for biopesticide adoption based on seven key factors, with legal frameworks and farm structure emerging as primary drivers. Addressing economic and educational barriers is crucial for widespread adoption. By implementing targeted policies, Mediterranean agriculture can become a model for sustainable practices, balancing productivity and environmental stewardship. Full article

The teaching of environmental education must change to promote critical, sustainable, and reflective engagement with environmental problems. This study introduces a social-science question for primary education focused on pharmaceuticals in surface water. The aims of the paper are to evaluate the level of students’ performance in arguing their answers in relation to the reference answer; their use and interpretation of provided materials from which they draw the evidence to justify their arguments; and the type of solutions they propose in the framework of sustainability. This is carried out by analyzing the content of their written reports and the discourse during their group discussions. Statistical tests are also used to compare their individual and group performance. The results show that students perform at an intermediate level. They use text and video effectively but struggle with graphs and maps. Their proposed solutions are contextually appropriate and consider multiple perspectives. Notably, their performance is similar whether working individually or in groups. All in all, this pedagogical intervention in the framework of scientific practices and transformative environmental education supports the development of scientific thinking and sheds light on how students process information when addressing socio-environmental issues.

The Social–Environmental System (SES) framework is crucial in understanding the intricate interplay between human societies and their environmental contexts. Despite its significance, existing SES delineation methods often rely on subjective judgment and struggle with the non-linear, multi-scale nature of SES data, leading to challenges in effective resource management and policymaking. This research addresses these gaps by proposing a novel, reproducible framework for SES boundary delineation that integrates both vector and raster data, utilizing advanced spatial optimization techniques and dimension reduction algorithms like UMAP to manage the non-linear characteristics of SES. The framework also leverages the SKATER algorithm for precise regionalization, ensuring spatial continuity and compactness while allowing user control over region selection and data dimensions. Applied to the Rio Grande/Bravo Basin, this approach demonstrates the practical utility and computational efficiency of the proposed method, offering a scalable solution adaptable to various regions. While focusing on this transboundary area, the study underscores how its framework can be generalized globally for addressing socio-environmental challenges while maintaining flexibility to accommodate local and regional specificities. The framework’s reliance on open-source tools further enhances its accessibility and reproducibility, making it a valuable contribution to SES research and practical environmental management.

American college towns tend to be very economically dependent on the college they host. If enrollment is high, the town thrives. However, when enrollment is low, the town faces socio-economic difficulties, including increased unemployment and struggling businesses. Furthermore, the seasonal presence of students poses an additional challenge. This study investigates tourism as a potential solution to diversify college towns’ sources of revenue based on community willingness and town assets. Data were collected via interviews with 50 community members from three different groups within the town. While environmental tourism shows great potential for community self-development, the Calgary model of competitiveness highlights the need for significant efforts to establish the required support systems.

Around the world, the development of large dams has been increasingly contested. India is no exception and has seen the mobilisation of powerful domestic and transnational socio-environmental movements against dams over more than four decades. In this context, the State of Sikkim in northeast India has been entangled in prolonged hydropower development conflicts since the late 1990s. This article analyses these conflictive entanglements between the Government of India, the State Government of Sikkim, power companies and Sikkim’s autochthonous tribe, the Lepchas. It zooms in on the period of 2011–2017, which saw an abrupt escalation of the conflicts to analyse the messy, deeply political and often unpredictable and contradictory world of dam construction and its contestations. Our analysis is informed by the power cube framework developed by John Gaventa. Our analysis shows how hydropower development is deeply intertwined with local patronage relationships. We show how local elections bring out dam conflict and the operation of power into the open, sometimes leading to abrupt and unexpected switches in positions in relation to hydropower development. We show that these switches should be seen not only as “strategic electoral tactics” but also and importantly as contentious political struggles that (re)configure power in the region. We show how in this process, powerful political actors continuously seek to stabilise power relations among the governing and the governed, choreographing a specific socio-hydraulic order that stretches way beyond simple pro- and anti-dam actors and coalitions as it is embedded in deep hydro(-electro) politics and power plays.

The timely and effective detection of forest fires is crucial for environmental and socio-economic protection. Existing deep learning models struggle to balance accuracy and a lightweight design. We introduce SWVR, a new lightweight deep learning algorithm. Utilizing the Reparameterization Vision Transformer (RepViT) and Simple Parameter-Free Attention Module (SimAM), SWVR efficiently extracts fire-related features with reduced computational complexity. It features a bi-directional fusion network combining top-down and bottom-up approaches, incorporates lightweight Ghost Shuffle Convolution (GSConv), and uses the Wise Intersection over Union (WIoU) loss function. SWVR achieves 79.6% accuracy in detecting forest fires, which is a 5.9% improvement over the baseline, and operates at 42.7 frames per second. It also reduces the model parameters by 11.8% and the computational cost by 36.5%. Our results demonstrate SWVR’s effectiveness in achieving high accuracy with fewer computational resources, offering practical value for forest fire detection. Full article

Urban rainstorms and flood disasters are the most common and severe environmental problems worldwide. Many factors influence rain-flood control simulation, forming a complex network system of interconnected and mutually constraining elements. In terms of spatial scale selection, existing research on rain-flood disaster risk largely relies on a single-scale infrastructure index system and has not yet focused on urban “gray-green-blue” spatial scale simulations for rain-flood storage. Regarding research methodology, applying system dynamics methods to the simulation of rain-flood storage and disaster prevention planning in watershed cities is still in its initial stages. System dynamics models can simulate the feedback interactions among various sub-elements in the coupled mega-system, fully addressing complex issues within the system structure that involve multiple variables, non-linear relationships, and numerous feedback loops, thereby compensating for the inadequacies of traditional linear models in the collaborative management of rain-flood risks. Taking the Changsha Guitang River Basin as an example, this paper constructs a system dynamics model covering four dimensions: natural environment, socio-economics, internal structure, and policy development. It aims to derive the optimal planning scheme for gray-green-blue spatial coordination in rain-flood storage by weighing four different development scenarios. The simulation results show: (1) Simply changing the surface substrates without considering rainwater discharge and the plan that emphasizes the construction of municipal drainage facilities will see the capacity gap for rain-flood storage-space construction continue to widen by 2035. This indicates that the plans mentioned above will struggle to bear the socio-economic losses cities face during rain-flood disasters. (2) The plan of combining gray and green infrastructures sees the rain-flood storage construction capacity turn from negative to positive from 2024, rising to 52.259 billion yuan by 2035. This reflects that the plan can significantly reduce the rainwater volume in the later stages of low-impact development infrastructure construction, mitigate rain-flood disaster risks, and reduce government investment in rain-flood disaster risk management, making it a relatively excellent long-term rain-flood storage space planning option. (3) The rain-flood regulation space planning scheme, under the combined effect of the urban “gray-green-blue” network system, sees the capacity for rain-flood storage construction turn positive a year earlier than the previous plan, reaching 54.232 billion yuan by 2035. This indicates that the scheme can not only effectively respond to extreme flood and rainstorm disasters but also maintain ecological environment benefits and mitigate the socio-economic losses caused by disasters, making it the optimal choice for future government disaster management planning. The research results provide a theoretical framework and practical insights for territorial spatial planning, rain-flood control management, and resilient city construction in watershed areas.

Geoscientists are involved in both the upstream and downstream side of the extractive industries. As explorationists and field geologists, they are often the first technical people related to extractive industries that communities meet. It is imperative in an increasingly globalized and holistic world that geoscientists gain greater awareness of the socio-economic impact of extractive industries and become a more proactive part of improving outcomes for all with respect to extractive industries. When Jigme Singye Wangchuk, the King of Bhutan, first suggested the concept of ‘Gross National Happiness’ (GNH) in 1972, it was met with widespread cynicism and puzzlement. Was the concept meaningful in a hard, economically competitive world? A series of measures, including the Human Development Index (HDI), the Gini Coefficient (GC), and the now annual World Happiness Report (WHR), are evolutionary responses to the 1972 GNH and are widely accepted as proxy measures of holistic human progress. These measures go beyond the narrow confines of Gross Domestic Product and similar economic proxies, placing economic parameters alongside the social, environmental, spiritual, human rights, health, and holistic societal issues. The broad conclusions of the plethora of metrics are that ‘happiness’ links to issues and ideas such as equity, minimal economic inequality, excellent governance, human rights, individual freedom, and so forth. We ask the question: what is the relationship between extractive industries (EIs) and GNH? We present a wide range of data and analytical diagrams/text examining potential correlations and associations between GNH and EIs. We examine potential relationships using global data and case studies for Papua New Guinea, Mongolia, the DRC, and Jamaica. The conclusions of this analysis of course suggest a complex relationship between EIs and GNH. We acknowledge that in situations of weak governance and institutions, EIs struggle to make any tangible difference with respect to GNH. A counter conclusion that EIs may even be a major cause of weak governance, which in turn suppresses happiness, must be seriously considered. We document examples where EIs have made a definitive positive improvement to GNH. Data suggest that hydrocarbon-rich countries have made better progress with respect to GNH than mineral-rich countries. However, the main conclusion is that the link between EIs and GNH remains a work in progress, and that a narrow focus on profit and shareholder return is an antithetical approach to the GNH paradigm. A key recommendation is that industry must adopt a far more active role (rather than merely a passive role) with respect to translating the many potential benefits of EIs into GNH than has hitherto been the case.

In agricultural landscape management, the conventional top-down approaches that primarily focus on market-led responses struggle to preserve the landscape elements essential for environmental sustainability. To address this deficiency, land use and land cover change (LUCC) scenarios promote an integrated understanding of landscape dynamics and highlight the inconsistency between the compartmentalisation of the public sector (“siloisation”) and the necessity for management that reflects the interdependencies of socio-ecological systems. This study investigates the extent to which the creation and dissemination of LUCC scenarios lead to modifications in the values, attitudes, and behaviours of local actors engaged in land management, giving particular emphasis to the role of these scenarios in encouraging integrated management. To accomplish this objective, we interviewed local actors who actively participated in the co-construction of the scenario narratives or learned about the scenarios during dissemination workshops. We then analysed the data via a thematic and lexicometric analysis. The findings highlighted the dual function of these scenarios as a catalyst for pre-existing political will to promote integrated management and as a tool for raising awareness about major environmental challenges. At the group level, the outcomes encompassed aspects such as basing political decisions on the results of scenarios and fostering collaboration between institutions. These outcomes were observed among the actors involved in co-constructing scenarios or those with pre-existing motivations to pursue integrated management initiatives. Additional personal outcomes included an increased awareness of environmental challenges and the consolidation of non-formalised knowledge. We argue that combining co-construction and dissemination enhances the outcomes of scenarios considerably. Full article

More and more cities in Southern Africa are struggling to manage their waste in a context of rapid urbanisation and increasing poverty. In the Cameroon’s largest city, Yaoundé, managing household waste is a growing concern. The public and the authorities cast blame on each other, and the actions taken by each party far from guarantee an efficient management of household waste, which litters the streets. Considering the above, this paper analyses the socio-political practices of stakeholders and their influence on household waste management in Yaoundé. Based on a qualitative survey that combined both a literature review and interviews, the research analysed the challenges related to household waste management with regard to the economy, the environment, and public health. In addition, a cartographic survey using KoboToolbox was conducted in all seven municipalities to analyse the geographical distribution of the waste areas, their size, and their status within the city organizational framework. In total, 264 waste dumps were collected, of which 110 were formal waste using a waste bin of varying size. Social constructivism, stakeholder theory, and strategic analysis were mobilized to analyse the urban waste governance in Yaoundé. Thus, the poor quality of household waste management in Yaoundé was explained using political, economic, sociocultural, and environmental parameters. The social practices and dynamics of the stakeholders generate undesirable consequences that hinder the achievement of the Sustainable Development Goals (SDGs). By combining social science and engineering methods, this research aims to demonstrate that the shortcomings of waste governance in Yaoundé are both a collective (authorities/public powers) and individual (citizens) matter.
