This review situates youth resilience within the context of climate justice, recognising that those in low- and middle-income countries (LMICs) disproportionately experience climate-related shocks due to systemic inequalities. Guided by the Preferred Reporting Items for Systematic and Meta-Analyses Protocol framework, a scoping review was undertaken to examine how youth in LMICs experience and respond to agrifood system vulnerabilities arising from climate change, economic disruptions (including COVID-19), and conflict, with a focus on education and employment outcomes. Systems thinking served as the central analytical approach to identify interdependencies, feedback loops, leverage points, and resilience pathways. The findings reveal limited research quantifying youth-specific vulnerabilities and resilience strategies within agrifood systems. While broad impacts are recognised, youth agency and adaptive capacities remain underexplored. The interactions among climate impacts, contextual vulnerability, health-productivity constraints, food insecurity and governance conditions create compounding risks that exacerbate food insecurity and social inequity among rural and urban youth. To address these gaps, the study proposes a conceptual framework that integrates climate justice principles into resilience-building strategies, promoting equitable access to resources, inclusive governance, and youth-led adaptation. By mapping interconnections across agrifood systems, climate, equity, education, and employment, the study charts resilience pathways toward socially inclusive, climate-adaptive, and economically sustainable food systems, underscoring the need for policies and research that centre youth agency and lived experiences.</p>","PeriodicalId":520363,"journal":{"name":"Environmental research.

Only official national dietary guidelines were included. Due to heterogeneity in how dietary and environmental impacts were calculated, results are represented in terms of increases and decreases, rather than average percentage change. <i>Results.</i> Of the forty-five papers included, only 4 measured biodiversity impacts, compared to 35 measuring greenhouse gas (GHG) emissions, 24 water, and 10 fertiliser use. Most studies used life cycle assessment to measure the potential land use and environmental impacts. All studies found an increase in fruit and vegetables would be needed to meet dietary guidelines, and all but two found a reduction in meat is required. Papers mostly reported reduction in resource in land use and GHGs (28/45 and 22/35 papers, respectively). Impacts on water, energy and biodiversity, which were less frequently included, were more mixed. Over half of the papers included policy recommendations (<i>n</i> = 29), with the most being to incorporate sustainability into dietary guidelines. <i>Conclusion.</i> A wider range of environmental outcomes should be included when assessing the environmental sustainability of dietary changes to get a more holistic view of the potential trade-offs and co-benefits that need to be navigated with these dietary shifts.</p>","PeriodicalId":520363,"journal":{"name":"Environmental research.

This paper examines how the structure of poultry sectors, producing meat, eggs, and game birds, shape disease risk and the possibilities for a resilient poultry ecology. Using a production and distribution network approach, we combine a desk-based review of industry, policy, grey, and published literature with qualitative data from 19 in-depth interviews, supplemented by field visits and engagement in stakeholder events. Our analysis shows that highly integrated and geographically concentrated poultry meat and layer systems interact with wild and semi-wild birds in ways which generate distinct challenges. Concentration of production and processing infrastructure, aging housing stock, consumer demand for free-range, and large-scale releases of game birds impact decisions around poultry governance and questions of risk around avian influenza incursion. We identify two cross-cutting 'entanglements' that condition avian influenza virus vulnerability: (1) poultry planning, where fragmented and often contested land-use decisions interact with environmental and biodiversity policies to shape exposure to wild and semi-wild ecologies; and (2) the insuring of poultry, where a market failure in private avian influenza insurance and uneven and contested state compensation regimes differentially distribute risk across producers and sectors. We argue that farm-level biosecurity, while necessary, is insufficient to secure Britain's poultry production under near-endemic avian influenza virus pressure. A more bio-resilient poultry future will require macro-level, multi-sectoral coordination that integrates spatial planning, infrastructure renewal, and equitable risk-sharing mechanisms for disease preparedness.</p>","PeriodicalId":520363,"journal":{"name":"Environmental research.

Fueled by climate change, increasingly volatile environmental and weather conditions in the Canadian Arctic territory of Nunavut have made these routes less reliable and more dangerous-jeopardizing availability of traditional foods. Qualitative research indicates communities adapt by grocery shopping. We modeled consecutive days of trail inaccessibility on total grocery and meat product sales, respectively, of a market-dominant retailer in 13 Nunavut communities. Although we hypothesized positive associations between trail inaccessibility and store purchasing, we observed negligible negative associations; meanwhile, socioeconomic factors like pay dates yielded strong, positive associations. In light of the null findings with respect to trail inaccessibility, we discuss key limitations of our approach and potential alternative explanations that might account for these unexpected findings, including the ecological level of analysis potentially masking subgroup vulnerabilities relative to exposure or outcomes, hunters' possible risk tolerance elasticities, and food sourced beyond our partner retailer (such as from the other major retail chain or through food sharing networks). Given the local nutrition and economic transitions-away from traditional food and subsistence livelihoods-communities may face reduced day-to-day vulnerability to trail accessibility disruptions. As the wage-based economy expands and the contemporary diet includes more energy-dense, processed store-bought food, Inuit communities may become increasingly sensitive to macro-political and economic pressures on their food system and sovereignty.</p>","PeriodicalId":520363,"journal":{"name":"Environmental research.

These gains are; reduced aggregate water consumption, sustained crop production, lower carbon emissions, and enhanced water availability for nature. We developed the model with limited data and hypothetical future scenarios from the Amman-Zarqa basin in Jordan. Given its significant irrigation and urban water demands and difficult decisions regarding future water allocation and nexus choices, this basin is a highly appropriate case study. The paper's primary aim is to demonstrate the iGains4Gains nexus model rather than to build an accurate hydrological model of the basin's water resources. The model addresses two critical questions regarding increased irrigation efficiency. First, can irrigation efficiency and other factors, such as irrigated area, be applied to achieve real water savings while maintaining crop production, ensuring greenhouse gas emission reductions, and 'freeing' water for nature? Second, with the insight that water conservation is a distributive/allocative act, we ask who between four paracommoners (the proprietor irrigation system, neighbouring irrigation systems, society, and nature) benefits hydrologically from changes in irrigation efficiency? Recognising nexus gains are not always linear, positive and predictable, the model reveals that achieving all four gains simultaneously is difficult, likely leading to trade-offs such as water consumption rebounds or increased carbon emissions. Demonstrated by its use at a workshop in Jordan in February 2024, iGains4Gains can be used by students, scientists and decision-makers, to explore and understand nexus trade-offs connected to changes in irrigation management. The paper concludes with recommendations for governing water and irrigated agriculture in basins where large volumes of water are withdrawn and depleted by irrigation.</p>","PeriodicalId":520363,"journal":{"name":"Environmental research.

However, for many countries, the optimal composition of locally contextualized healthy and sustainable diets is unknown. The Gambia is vulnerable to climate-change-induced future water scarcity which may affect crop yields and the ability to supply healthy diets. This study identifies potential shifts in Gambian diets that could make diets healthier and reduce the associated agricultural water footprint (WF), and assesses the cost and affordability implications of such dietary changes. Gambian Integrated Household Survey (IHS) food consumption data was combined with market prices, food expenditure and agricultural WF data. Current dietary patterns were compared with World Health Organization (WHO) dietary guidelines and optimized using linear programming to identify least-cost diets that met nutrition recommendations and reduced agricultural water use. Optimization scenarios explored the maximum reduction in green water use that could be achieved with 'culturally-acceptable' dietary shifts, and the magnitude of shifts required to maintain green water use at current levels. On average, current diets provide adequate energy and have appropriate macronutrient composition. However, only 14% of households consume enough fruit and vegetables (F&Vs), and consumption of added sugars exceeds recommendations. With 'culturally-acceptable' changes in consumption, agricultural water use could decrease by 10%-13% or increase by 9%, depending on the baseline dietary pattern. Extreme dietary shifts will be required to maintain water use at 2015 levels with projected population growth. To meet WHO recommendations, dietary costs would increase by 43% compared to the current baseline. Healthy and green water-saving diets would require 48%-63% of average household expenditure to purchase, which is unaffordable for almost half of the population. F&Vs alone account for 31%-40% of the cost of optimized diets compared to 12% of current diets. Dietary modification has the potential to improve the nutritional quality of Gambian diets while reducing agricultural water use, but the required changes are likely to be unaffordable for a large proportion of the population. Improving availability and affordability of nutritious foods-particularly F&Vs-will be crucial for the accessibility of healthy and sustainable diets in the Gambian population.</p>","PeriodicalId":520363,"journal":{"name":"Environmental research.
