Agrifood systems globally are confronted with mounting challenges, including hunger, rising food prices, and geopolitical tensions. Conventional agricultural models face criticism for causing environmental degradation and increasing poverty, which emphasizes the need for sustainable alternatives. Agroecology emerges as a promising solution that embodies a holistic, farmer-centric countermovement against corporate-led food systems. However, the practical implementation of agroecology as practice, science and social movement faces considerable barriers. Sceptics argue that agroecology is too complex, labor- and knowledge-intensive and cannot keep up with the production level of conventional agriculture. The case study was conducted in Tanzania’s Southern Highlands, based on expert interviews and literature analysis. It finds 18 factors that potentially impede the implementation and dissemination of agroecological approaches. Impeding factors exist in all three agroecological approaches. Most obstacles were identified with agroecology as a practical approach. Agroecology as a social movement was only addressed to a limited extent. Main challenges within the approaches include the fear of high financial, time, and energy expenditures when implementing agroecology, difficulties in adopting agroecological practices, the desired and equal collaboration between farmers and researchers, diverging and different definitions and understandings of agroecology, gender relations in farming activities and market and price dependencies for generating income. The study emphasizes the need for collaborative efforts, awareness, and supportive policies to promote agroecology effectively. The research contributes to bridging the gap between theoretical debates and practical applications of agroecology and urges rethinking and revising its conceptualization.

Human–elephant conflict (HEC) is a serious social–ecological problem in Sri Lanka’s elephant range regions, as between 200 and 400 elephants have been killed annually over the last years, and more than 1200 people have died from the consequences of elephant encounters within a decade. Crop foraging causes economic damage to farming households. The study aims to understand factors driving vulnerability to HEC among the population. Employing a cross-communal multi-item large-N field survey (N = 651), authors were able to describe living conditions and perceptions of Sri Lankan villagers affected by HEC. By running a multiple regression analysis with correlated variables, the study is able to correlate independent variables to vulnerability, namely socio-economic conditions, environmental change and land-use, and awareness. Furthermore, a vulnerability map has been created, identifying Puttalam, Anuradhapura, Kurunegala, Matale, and Polonnaruwa districts as conflict hotspots. Private electric fences as a widespread protection measure were found to have unintended negative side-effects to non-protected households. The findings suggest the urgent need to upscale public policies mitigating the consequences of HEC on affected populations by reducing overall vulnerability to environmental hazards, including human–wildlife conflict.

Sri Lanka's vulnerability to climate change-induced natural disasters, particularly floods, under-scores the urgent need for an integrated approach to disaster risk management (DRM) that ad-dresses the interconnected challenges within the water-food-land-energy nexus. The Deduru Oya basin, located in the north-western region, exemplifies this vulnerability, with its predominantly intermediate climatic zone susceptible to flooding. While the focus has traditionally been on flood risk reduction, it is imperative to recognize the broader implications of floods on water, food, land, and energy systems. This study aims to strengthen data acquisition and management efforts to better understand rainfall trends and their impact on the water-food-land-energy nexus in the Deduru Oya basin. By compiling 60 years of rainfall data and conducting time series analysis, we observed a decreasing trend in monthly rainfall, particularly during the South-West Monsoon, Second Inter Monsoon, and North-East Monsoon seasons. These findings have significant implica-tions for water availability, agricultural productivity, land use patterns, and energy generation in the basin. Moreover, the malfunction of stakeholders' responsibilities for local-level flood risk management exacerbates the challenges faced by communities living in flood-prone areas. By in-tegrating insights from this study into flood risk management strategies, stakeholders can develop holistic approaches that not only mitigate flood risk but also enhance resilience across the water-food-land-energy nexus. This interdisciplinary approach will inform policymakers, flood manag-ers, practitioners, and the community in formulating effective strategies to address the multifacet-ed challenges posed by floods in the Deduru Oya basin and beyond.

Human-elephant conflict (HEC) in Sri Lanka has escalated over the recent years, with, on average, 300 elephant deaths annually and human casualties of around 90 per year. Employing field-based qualitative methods, this contribution identifies causes and contexts of human-elephant conflict in those parts of the Sri Lankan dry zone most severely affected. We have used field observations as well as semi-structured interviews with experts and affected villagers as primary data collection techniques. The findings show that (a) human-elephant conflicts are the result of land-use decisions, encroachment on elephant corridors, changes in agricultural production systems, and commercialization of land, and that (b) there is a deep division between the environmental knowledge and practices of rural people and the conservation governance provided by government authorities. Furthermore, both traditional and modern mitigation approaches fail to reign in HEC effectively. The insufficient implementation of HEC mitigation measures, and a severe disconnect between the needs and anxieties of rural people and conservation policies, render the management of human-wildlife interactions ineffective. This suggests a need for fundamental reform of elephant conservation policy in Sri Lanka.

There is a vivid scientific debate on how climate change affects stability, resilience, and conflict dynamics of human societies. Environmental security and collapse theory are theoretical approaches that claim severe negative impacts of climatic disasters on political stability, allegedly through the vector of food insecurity. Yet there is a disconnect between this work and the rich body of knowledge on food insecurity and society. The literature is fairly unanimous that (a) drought does not necessarily lead to famines, since (b) famines have a political context that is often more important than other factors; in addition, (c) famines and the distribution of suffering reflect social hierarchies within afflicted societies, and (d) even large-scale famines do not necessarily cause collapse of a polity’s functioning, as (e) food systems are highly interconnected and complex. As an illustrative case, the paper offers a longitudinal study of Malawi. By combining environmental history and analysis of Malawi’s idiosyncratic (post-)colonial politics, it discusses the possible connections between droughts, food insecurity, and political crises in the African country. The single-case study represents a puzzle for adherents of the “collapse” theory but highlights the complex political ecology of food crises in vulnerable societies. This has implications for a formulation of climate justice claims beyond catastrophism.

Participatory approaches within development programs involving common-pool resources are intended to revive a community’s role in managing these resources. Certainly, to ensure the successful and equitable use of such resources, community participation is essential. However, in many cases, attempts at applying a participatory approach often fail to genuinely engage all subgroups within a community due to assumptions of homogeneity and a lack of understanding of the deep socio-political divisions between people. As a result, development programs can be plagued by these pre-existing power relations, potentially resulting in tokenistic community participation and the continuation of elite capture of natural resources to the same extent or worse than before a development program has begun. This in turn can negatively impact good governance and the fair distribution of a common pool resource. This paper explores the use of participatory approaches in water projects, assessing to what degree power relationships impact water management programs. Using a qualitative approach, the paper identifies key challenges of participatory water governance through case studies from Turkey, India, and Sri Lanka, exploring: lack of social trust, elite capture of participatory processes, power heterogeneity and imbalances at the micro-level, and a lack of inclusive participation in decision-making. Based on the analysis of these case studies, this paper argues that it is essential for participatory development interventions to understand socio-political power relations within a community—an inherently complex and contested space. The so-called “exit strategy” of a community project play a key role to decide the project sustainability that grants the “community ownership” of the project. Such an understanding can bring about greater success in development interventions attempting to address water-related issues.

Human–elephant conflict (HEC) is a severe and much-debated issue in Sri Lanka. An average of two hundred animals are intentionally killed, and seventy to eighty human casualties are counted each year. The Sri Lankan elephant (Elephas maximus maximus) is an endangered subspecies. The reported elephant mortality rates are high. On the other hand, human–elephant conflict also leads to hardship and trauma among rural populations. This research paper reviews causal explanations for HEC in Sri Lanka, tracing underlying narratives and connecting broader conservation theory and practical approaches. The paper discusses potential causes and contexts of HEC in Sri Lanka, including historical factors (i.e., colonial hunting and land-use changes), poaching, habitat loss due to population growth, crop-raiding behaviour, problem animals, and changes in agricultural production systems. The review concludes that socio-economic and cultural factors in HEC in Sri Lanka are poorly explained, and more research should focus on the underlying conditions of rural populations’ vulnerability.

This contribution is a critical review of research on the global agri-food system directly or indirectly identified as political ecology (PE). It shows how food, famine and agricultural production were important topics to early proponents of PE, especially with regards to a critique of neo-Malthusian thought. It then traces further developments in the field and highlights the productive tension between materialist and poststructuralist streams, as well as the influence of actor-network theory. Further on, the paper discusses three neighbouring theories and frameworks with a potential to stimulate current political ecologies of food and agriculture, namely critical agrarian studies, food regime theory and world-ecology. Finally, seven clusters of potential research topics for a political ecology of the global agri-food system are identified. In conclusion, the relevance of PE as a theoretical lens is reiterated and the need for fruitful application of political ecology and related approaches is expressed.
