The increasing severity of climate change poses profound challenges to global food security, particularly affecting vulnerable populations such as migrants and refugees. This scoping review examines the nexus between climate change, food security, and migration, focusing on the impacts and responses within affected communities. Guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR), this review synthesized literature across multiple databases, including Ovid MEDLINE, Embase, Global Health, Public Health, Web of Science, and PsycINFO. The search yielded 908 records, with nine articles meeting the inclusion criteria. Across studies, climate-related stressors such as rainfall variability, flooding, and drought were consistently linked to livelihood disruption and food insecurity, often shaping migration and displacement decisions. However, food security outcomes were defined and measured inconsistently, ranging from crop yields and food availability to coping strategies and self-reported hunger, limiting comparability across studies. Evidence on food security initiatives was largely descriptive, with few studies assessing intervention effectiveness or post-displacement food security outcomes. Overall, the mapped literature emphasizes food insecurity as a key mediating pathway between climate change and mobility, but reveals important gaps related to standardized outcome measures, evaluation of food security initiatives, and the food security experiences of displaced populations at destination.

The degradation of wetlands and forests is still a threat to the supply and recovery of ecosystem services in the tropics. Studies comparing restoration measures and ecosystem service recoveries are fragmented. This study investigated the spatial extent and drivers of wetland/forest degradation, and assessed the effects of restoration measures on the recovery of ecosystem services and resilient livelihoods. A cross-sectional household survey was conducted targeting households adjacent to restored and unrestored wetland/forest ecosystems. The data was analyzed using a Binary Logistic regression to characterize earlier and recovered ecosystem services between forest and wetland ecosystems. High spatial-resolution optical satellite imagery from the Airbus constellation was obtained and analyzed to examine wetland and forest degradation. Our findings revealed that the spatial extent of degraded land under wetlands and forests decreased between 2023 and 2025. Ecosystem service degradation was primarily driven by chronic poverty, excessive water abstraction, population growth, burning practices, overharvesting of resources, overgrazing, cultivation, infrastructure development, and the invasion of alien species (p < 0.05). The counteractive ecosystem restoration activities undertaken included mobilization and sensitization of communities on wetland restoration, wetland demarcation, revegetation, establishment of flood control measures, and provision of alternative livelihoods (p ≤ 0.05). The multiple direct and indirect ecosystem service recoveries reported were provisioning services (increases in pasture, enhanced livestock production, increased soil productivity, health-related benefits from crops and livestock products) and regulating services (improved water quality/quantity). The ecosystem service recoveries were more significant in the restored wetlands than the forests. The indicators of enhanced ecosystem-based resilient livelihoods included increased household incomes, higher livestock yields, increased crop productivity, improved health from crop/livestock products, improved water quality/quantity, and enhanced scenic beauty and tourism (p < 0.05). The restoration activities in degraded wetland systems had more potential to facilitate full recovery of the wetland ecosystem compared to the absence of interventions. This evidence highlights the need to restore high-ecological-sensitive ecosystems to sustain the delivery of ecosystem services for community and environmental resilience. Full article

The COVID-19 pandemic has underscored and intensified existing structural inequalities, particularly in urban centers of the Global South. This paper revisits the Sustainable Livelihoods Framework (SLF), originally designed for rural contexts, proposing its adaptation to centralize mobility as a critical analytical axis in urban contexts. Through an examination of São Paulo, Brazil, we explore how mobility restrictions, access to natural capital, and health outcomes intersected during the pandemic, disproportionately affecting vulnerable populations. To explore the application of the adapted framework, we analyze two contrasting neighborhoods in São Paulo, highlighting how different urban contexts mediate the impacts of systemic crises. By integrating mobility into the SLF, we aim to provide a more nuanced tool for analyzing and addressing urban vulnerabilities in times of systemic crises. Full article

Vulnerabilities in local food systems revealed by the COVID-19 pandemic were especially evident in highly tourism-dependent islands. This underscores the crucial role of agriculture in ensuring socio-ecological resilience, food security, and livelihood options in these contexts. Yet despite renewed policy attention, sustaining local farming in remote island settings continues to face numerous challenges. Amid growing recognition of the ways in which collective imagination shapes (and constrains) sustainability transformations, this paper applies the conceptual lens of imaginaries to examine agricultural futures in the Galápagos Islands and to explore the question of why agriculture remains marginal, despite widespread acknowledgement that supporting sustainable farming is central to the archipelago’s long-term sustainability. Through reflexive thematic analysis of policy documents, grey literature, and semi-structured interviews, the paper shows how imaginative spaces of possibility around food futures in Galápagos are conditioned by the powerful entanglement of hegemonic conservationist imaginaries with touristic imaginaries of an uninhabited wilderness. Within this contested terrain, five overlapping and co-constituting imaginaries of agriculture are distinguished, oriented variously around conservation priorities, technocratic planning, entrepreneurial growth, traditional livelihoods, and agroecological transformation. The analysis highlights how these imaginaries mobilize contrasting logics of support and mechanisms of change and illustrates how they complicate simplistic binaries, for example, between pristine and human-managed ecosystems, or between technological and holistic approaches to farming. The paper underscores the importance of paying critical attention to imaginaries of agriculture in order to navigate pathways toward more sustainable and resilient food systems in ecologically fragile island contexts.

Using the Danjiangkou Reservoir resettlement as a case study, this research adopts a policy lifecycle perspective to examine the evolutionary mechanisms of livelihood transformation and institutional adaptation under large-scale hydraulic development. The findings reveal that China’s resettlement governance is not merely an economic practice of resource redistribution and livelihood reconstruction but a deeper process of institutional learning and social reconfiguration. The transformation of Danjiangkou migrants—from administrative dependence to self-organized recovery and finally to development empowerment—reflects a structural shift in governance logic from control-oriented mobilization to collaborative and inclusive modernization. The study elucidates the dynamic interaction between institutional supply and social agency, arguing that the state acts not only as a resource provider but as an institutional recalibrator that fosters endogenous governance capacity through social self-organization. The identity transformation of migrants—from excluded subjects to integrated citizens—demonstrates that recognition, participation, and social capital are central to achieving social justice and sustainable governance. Practically, sustainable resettlement requires institutional flexibility and social empowerment, emphasizing long-term capacity building over short-term relief. The Danjiangkou experience reveals the deeper logic of Chinese modernization—a transition from control to collaboration, from survival to development, and from outsiders to citizens—offering valuable insights for equitable and resilient resettlement governance.

Rapid economic development in the past four decades in China has brought about significant consequences for people’s livelihoods. Healthy social mobility is fundamental for equality of opportunity, economic vitality, and socioeconomic sustainability. This paper examines the intragenerational livelihood mobility of urban residents in recent decades based on a case study in Guangzhou City and Foshan City, Guangdong Province, Southeast China. Longitudinal livelihood trajectory surveys have been investigated to gain research data. The primary determinants of livelihood mobility were also elucidated through analysis of muti-logistic regression. The results show that five livelihood trajectories are summarized based on their vertical movements in social status. The results further indicate that class polarization exists in urban residents’ mobility. 48.2% of respondents have experienced upward mobility, and 33.6% of them have even stepped over social classes. Meanwhile, the livelihoods of the others remained unchanged or suffered downward mobility. Respondents with male gender, better educational attainments, positive personality, and lower hierarchies of first occupations are associated with a higher probability of upward mobility. These results suggest that wealth redistribution among different social groups should be implemented to promote the benefits of economic growth being shared more broadly, and ultimately to boost socioeconomic sustainability.

The rapid growth of on-demand services in Sub-Saharan Africa has intensified reliance on internal combustion engine (ICE) motorcycles for last-mile delivery, with Cape Town exemplifying both the opportunities and challenges of this trend. While motorcycles provide affordable and flexible mobility, their disproportionate emissions, high operating costs, and exposure to volatile fuel prices create pressing economic and environmental concerns. This paper investigates the implications of electrifying Cape Town’s last-mile delivery fleet by modelling the operational dynamics of 39,005 delivery trips performed by 385 motorcycles. Using empirical data, the study simulates fleet electrification under two battery-swapping scenarios—daytime swapping only and a hybrid swapping plus overnight charging model—while testing unmanaged and managed charging strategies. Results show that downsizing the fleet could reduce system resources by more than 50%, lowering capital and grid burdens, with managed charging offering long-term operational savings. Managed charging approaches, particularly off-peak balancing and solar-following, successfully mitigate grid strain and enhance solar utilisation, though they demand larger battery pools, a trade-off quantified by a techno-economic analysis. Crucially, pairing electrification with decentralised solar generation demonstrates the potential for a resilient, net-zero system insulated from load shedding. The findings provide a transferable framework for African cities to decarbonise urban logistics while safeguarding rider livelihoods and grid stability. Full article

This study explores the readiness of Micro and Small Enterprises (MSEs) in Mexico, specifically grocery stores, to implement the Virtual Value Chain (VVC) through Information and Communication Technologies for Development (ICT4D). A mixed-methods approach was used, combining diagnostic tools, structured surveys, and interviews. Quantitative data were analyzed using descriptive statistics, correlation analysis, and machine learning to identify digital adoption patterns. The results indicate that limited technology adoption remains the main obstacle to VVC integration. Significant associations were found between digital engagement and the age and educational level of store managers. Key digital gaps persist in inventory control, supplier coordination, and demand forecasting. Although machine learning models did not significantly outperform baseline predictions on willingness to adopt technology, the findings emphasize the potential of targeted training and accessible mobile solutions. The study proposes a new diagnostic and predictive framework to assess VVC readiness in low-resource contexts. It shows that ICT, when strategically aligned with business operations and paired with adequate training, can enhance sustainability and livelihoods. Although the study is limited to one geographic area and one business sector, it offers a foundation for scaling similar initiatives. The findings support context-sensitive strategies and capacity-building efforts tailored to the realities of MSEs in emerging economies. Full article

Rapid urbanization in developing countries has widened the gap between urban and rural development, due to inefficient land markets and weak institutional systems in rural areas. China’s innovative “Urban–rural Construction Land Linkage” policy was designed to address this imbalance by encouraging rural land consolidation and creating a transferable development rights mechanism. While this approach has shown potential in improving the utilization efficiency of existing construction land and continuously supplying urban development space, concerns remain about its actual benefits to villagers and rural development, with some arguing it disrupts traditional livelihoods and favors government interests over rural needs. To respond to this debate, this study investigates two core questions: first, does China’s transferable land development rights (TDR) program genuinely improve rural welfare as intended; second, why does the theoretically preferred self-organized governance model sometimes fail in practice? To address these research questions, this paper develops a new analytical framework combining the IAD framework of Ostrom with the hierarchical institutional framework of Williamson to examine three implementation approaches in China’s TDR implementation: government-dominated, market-invested, and self-organized models. Based on case studies, surveys, and interviews across multiple regions, this study reveals distinct strengths and weaknesses in each approach in improving villagers’ lives. Government-dominated projects demonstrate strong resource mobilization but limited community participation. Market-based models show efficiency gains but often compromise equity. While self-organized initiatives promise greater local empowerment, they frequently face practical challenges including limited management capacity and institutional barriers. Furthermore, this study identifies the preconditional institutional environment necessary for successful self-organized implementation, including clear land property rights, financial support, and technical assistance. These findings advance global understanding of how to combine efficiency with fair outcomes for all stakeholders in land governance, which is particularly relevant for developing countries seeking to manage urban expansion while protecting rural interests.

Island settlement landscapes exhibit distinctive characteristics, and investigating their spatio–temporal differentiation features and formation mechanisms is crucial for effective landscape conservation. This study selected Qida Village, Beigang Village, and Jingsha Village in Fuzhou City, Fujian Province, China, as representative cases. It constructed an integrated evaluation framework termed “livelihood transformation–two dimensional expansion–three dimensional form” and systematically analyzed the spatio–temporal differentiation characteristics and driving mechanisms of island settlement landscapes under the context of livelihood transformation by integrating multi-source data. Research findings indicate that livelihood transformation significantly affects both the horizontal expansion and vertical evolution of settlement landscapes. Aquaculture-based villages demonstrate a high expansion rate (15.10%) and pronounced vertical differentiation (building height difference ratio of 13.30) due to industrial agglomeration. Tourism service-oriented villages, influenced by policy regulation, exhibit low architectural style heterogeneity (0.35) and a harmonized skyline. Villages experiencing significant out-migration show a high housing vacancy rate (64.70%) and reduced spatial compactness (0.13) due to population decline. The livelihood model drives landscape differentiation through the “population mobility–economic investment–land use” pathway, where capital accumulation and policy constraints emerge as key determinants of spatial form heterogeneity. This study provides a solid theoretical foundation and methodological support for the differentiated governance of island settlement landscapes. Full article

We document and analyze an emblematic case study of non-indigenous peasant autonomy and re-peasantization in Sa Kaeo province in the Issan region of Thailand, using a mostly qualitative, single case-study methodology. The Kok Edoi autonomous community, whose members engage in community forest management and increasingly in agroecological farming, was founded more than twenty-five years ago as the product of a land occupation by landless peasants associated with the national Thai social movement, the Assembly of the Poor (AoP), which is part of the global peasant movement, La Via Campesina (LVC). Partially inspired by opportunities given to the community and to AoP by LVC to learn and gain inspiration from Latin American experiences such as the Zapatistas in Mexico, Kok Edoi autonomy exemplifies how the exchange of social movement knowledge and experience can help shape and strengthen local struggles, and it is also suggestive of autonomy as an alternative pathway of resistance and sustainable development in Thailand. We review the literature on territorial autonomy, re-peasantization, and community forestry and autonomy in Thailand and the world. Situating Kok Edoi in Thai history concerning policies and conflicts around land and forests, we examine the type, dimensions, and facets of autonomy and re-peasantization present in Kok Edoi to demonstrate how these factors contribute to the community being considered an emblematic case of peasant autonomy, peasant land occupation, peasant management of and livelihood derived from natural resources, more autonomous alternative markets, collective accumulation, and political training and mobilization that contributes to a class-based national movement. This is novel in an academic literature that has to date focused principally on indigenous autonomy, largely in Latin America. Full article

Exploring the impact of national park construction on county-level livelihood and well-being holds significant implications for enhancing social livelihood. This study treats Wuyishan National Park Construction (WNPC) as a quasi-natural experiment, utilizing panel data from 138 counties (2011–2023) to construct a county-level livelihood and well-being index through the CRITIC weighting method. Kernel density estimation and the Theil index are applied to depict the spatiotemporal dynamics of WNPC. Moreover, the difference-in-differences model and mediating effect model are employed to assess the impact and mechanisms of WNPC on livelihood and well-being. The results reveal that, in the period 2011–2023, livelihood and well-being scores ranged from 0.1329 to 0.4565, indicating considerable scope for improvement. Over time, inter-county disparities narrowed, displaying a spatial pattern of “higher in the east and west, lower in the middle.” Overall disparities remained pronounced, driven chiefly by within-region variation, and Jiangxi displayed notably larger internal gaps than Fujian and Zhejiang. Benchmark regressions confirm that WNPC significantly improved livelihood and well-being, with robust results according to multiple tests. Mechanism analysis indicates that WNPC enhances livelihood and well-being by promoting population mobility and improving infrastructure. Heterogeneity analysis suggests that compared to industrial counties, WNPC has a stronger positive effect on the livelihood and well-being of agricultural counties. Based on this, it is suggested that WNPC promotes population mobility and improves infrastructure construction. This study provides a scientific basis and decision-making reference for achieving high-quality construction of national parks and enhancing livelihood and well-being. Full article

This study investigates the gendered nexus between climate change, food insecurity, and conflict in Plateau State, Nigeria. This region in north-central Nigeria is marked by recurring farmer–herder clashes and climate-induced environmental degradation. Drawing on qualitative methods, including interviews, gender-disaggregated focus groups, and key informant discussions, the research explores how climate variability and violent conflict interact to exacerbate household food insecurity. The methodology allows the capture of nuanced perspectives and lived experiences, particularly emphasizing the differentiated impacts on women and men. The findings reveal that irregular rainfall patterns, declining agricultural yields, and escalating violence have disrupted traditional farming systems and undermined rural livelihoods. The study also shows that women, though they are responsible for household food management, face disproportionate burdens due to restricted mobility, limited access to resources, and a heightened exposure to gender-based violence. Grounded in Conflict Theory, Frustration–Aggression Theory, and Feminist Political Ecology, the analysis shows how intersecting vulnerabilities, such as gender, age, and socioeconomic status, shape experiences of food insecurity and adaptation strategies. Women often find creative and local ways to cope with challenges, including seed preservation, rationing, and informal trade. However, systemic barriers continue to hinder sustainable progress. This study emphasized the need for integrating gender-sensitive interventions into policy frameworks, such as land tenure reforms, targeted agricultural support for women, and improved security measures, to effectively mitigate food insecurity and promote sustainable livelihoods, especially in conflict-affected regions.

Peat fires are a major hazard to human and animal health and can negatively impact livelihoods. Once peat fires start to burn, they are difficult to extinguish and can continue to burn for months, destroying biomass and contributing to carbon emissions globally. In areas with limited accessibility and periods of thick haze and fog, these fires are difficult to detect, localize, and tackle. To address this problem, thermal infrared cameras mounted on drones can provide a potential solution since they allow large areas to be surveyed relatively quickly and can detect thermal radiation from fires above and below the peat surface. This paper describes a deep learning pipeline that detects and segments peat fires in thermal images. Controlled peat fires were constructed under varying environmental conditions and thermal images were taken to form a dataset for our pipeline. A semi-automated approach was adopted to label images using Otsu’s adaptive thresholding technique, which significantly reduces the required effort often needed to tag objects in images. The proposed method uses a pre-trained ResNet-50 model as a backbone (encoder) for feature extraction and is augmented with a set of up-sampling layers and skip connections, like the UNet architecture. The experimental results show that the model can achieve an IOU score of 87.6% on an unseen test set of thermal images containing peat fires. In comparison, a MobileNetV2 model trained under the same experimental conditions achieved an IOU score of 57.9%. In addition, the model is robust to false positives, which is indicated by a precision equal to 94.2%. To demonstrate its practical utility, the model was also tested on real peat wildfires, and the results are promising, as indicated by a high IOU score of 90%. Finally, a geolocation algorithm is presented to identify the GNSS location of these fires once they are detected in an image to aid fire-fighting responses. The proposed scheme was built using a web-based platform that performs offline detection and allows peat fires to be geolocated. Full article

Urban green spaces (UGSs) play a pivotal role in sustaining the livelihoods of urban dwellers. This study sought to explore the impact of UGSs on livelihoods in Bulawayo and Johannesburg cities. A mixed-methods approach was used to develop a nuanced understanding of the nexus between UGSs and the livelihoods of the residents. A questionnaire survey (n = 658) with 329 participants from each city and 20 interviews were used to gather and generate data. Twelve types of UGSs were identified, with a relatively large proportion of the participants recognizing informal recreational areas as the common type of urban green space (UGS) in both cities. Domestic gardens, cemeteries, parks, woodlands, institutional green spaces, street trees, wastelands, commonages, and green roofs were other green spaces in both cities. Economically, job opportunities emerged in areas such as selling wares, photography, and the collection of firewood and wild fruits for sale. Likewise, farming activities and property values increased. Socially, they were valuable recreation and leisure spots for picnicking, dog walking, dating escapades, mental and spiritual wellness as well as education. Environmentally, UGSs were special in terms of medicinal provisions and aesthetics. However, urbanization and encroachment are undermining the extent of livelihood benefits. Therefore, it is imperative to revitalize UGSs by instituting robust partnerships and collaboration between government agencies, mobilize resources and expertise, value addition to existing UGSs, rigorous education to promote better appreciation, inclusion of the locals in the design process so that green spaces meet their needs and priorities, and establishing effective maintenance and management systems that ensure sustainability of UGSs.
