Climate change impact on urban food gardens: implications for adaptation strategies and food and nutrition security in townships in Pietermaritzburg Kwazulu-Natal, South Africa
2026Nthabeleng Tamako, Joyce Chitja · Agriculture & Food Security · South Africa
This study examined the impact of climate change on urban food gardens in Sobantu and Mpophomeni townships in Pietermaritzburg, KwaZulu-Natal, South Africa. Face-to-face interviews with 103 randomly selected participants revealed that climate change disproportionately affects resource-limited urban farmers, leading to erratic rainfall, pests, and natural disasters. Elevated temperatures, shifting weather patterns, and new pests and diseases significantly impact food gardens, affecting seed and crop selection and contributing to food insecurity.

2026Hannah Bücheler, Christine Bosch · Agroecology and Sustainable Food Systems · Germany
This paper explores the potential of Community-Supported Agriculture (CSA) in Germany, applying Erik Olin Wright’s concept of real utopia to assess if CSA challenges capitalist structures. Drawing on secondary literature, the study evaluates the desirability, feasibility, and achievability of CSA. The results suggest that CSA in Germany qualifies as a real utopia, but faces limitations to growth due to implementation constraints such as the need for additional market channels and access to land.

2026Jenkins E. M., Heafner H., Montgomery J., Soumano V., Paltseva A. A. · iScience · 米国・シカゴ
Portable X-ray fluorescence measurement of seven trace elements in 233 topsoil samples from five Chicago parks. Lead, arsenic, copper, zinc and chromium exceeded Illinois background levels in 89–100% of samples; arsenic exceeded EPA screening levels in 94% of samples and lead in 7%. Contamination was higher at parks farther from the city centre — Douglass and Humboldt parks, in predominantly minority, lower-income neighbourhoods — than at Cottontail, Grant and Webster. Principal-component analysis identified an anthropogenic signature (PC1, 51.7%) driven by Pb, Zn, Cu and As and a geogenic signature (PC2, 17.0%) associated with Mn and Ni. Areas of Douglass and Humboldt parks were classified as not safe for gardening in native soil; Webster as safe with minor restrictions. The authors conclude that park-soil contamination follows socioeconomic gradients, reflecting environmental injustice and a need for targeted remediation.
Contamination & food safetyHealthPolicyCommunityThe association between climate-smart agriculture practices adoption and farm income and wealth of small-scale urban crop farmers in eThekwini municipality, with implications for food and nutrition security
2026Khumalo N. Z., Sibanda M., Mdoda L. · Frontiers in Nutrition · 南アフリカ・エテクウィニ市（ダーバン）
A multi-stage sample of 412 small-scale urban crop farmers in eThekwini municipality, South Africa, with a conditional mixed process model relating a composite index of climate-smart agriculture adoption (agroforestry, conservation agriculture, crop diversification, rotation, cover crops, drought-tolerant crops, mulching, organic manure, wetland use, soil conservation) to farm income and a wealth index. Adoption was positively associated with both, but the authors state the estimated income association is "relatively modest" and should be read with caution. Several socio-economic variables showed counterintuitive associations, and because existing agricultural training showed a weak association with income-enhancing adoption, the authors call for context-specific, outcome-oriented training and extension rather than more of the same.

2026Büşra Gül KARACA, Duygu GÖKCE · Kent Akademisi · Global
This study comprehensively examined 26 scientific studies published between 2008 and 2025 from a spatial perspective, demonstrating that food desert formation is a multi-layered structural problem directly related to spatial planning processes and urban planning decisions, rather than individual socioeconomic deficiencies. The literature review revealed that food deserts are systematically produced by planning-based practices such as single-function zoning decisions, single-centered urban development models, and the absence of urban agriculture in legislation, not solely by a lack of physical access. Access disadvantages persist, particularly in peripheral neighborhoods and areas with high concentrations of low-income groups, and a significant gap exists in developing applicable policies for medium-sized cities due to the literature's focus on metropolitan areas.

2026Never Assan, Justice Sibanda, Betty Mukuwapasi, Reason Rumbidzai Charachimwe, Edmore Masama · Journal of Frontiers in Multidisciplinary Research · Sub-Saharan Africa
Urban animal agriculture (UAA) in Sub-Saharan Africa is presented as a solution for food security but faces challenges including gender inequality, climate change, inadequate legislation, and environmental degradation. While UAA aims to enhance household food security and alleviate poverty, it also encounters environmental issues such as resource competition, water resource strain, improper manure management, greenhouse gas emissions, noise, and nuisance. Sustainable UAA requires semi-intensive silvopastoral and mixed crop and livestock systems to reduce environmental impact and enhance local food production.

2026Magdalena Raftowicz, Mirosław Struś · · Europe
This chapter establishes a theoretical framework for examining the development of Community-Supported Agriculture (CSA). It argues that CSA aligns closely with sustainable development theory and should be regarded as an alternative to industrial agriculture. The analysis concludes that CSA constitutes a form of social and constructive innovation consistent with the sustainable development paradigm. However, the low level of social capital represents a key barrier to implementing the classical CSA model in Central and Eastern Europe.

2026Anton Parisi, Felix Zoll, Faiza Darkhani · Agriculture and Human Values · Germany
Aspects of diversity, equity, and inclusion (DEI) in German alternative food networks (AFNs) were explored through literature, interviews, and one stakeholder workshop. The inquiry found that while women are better represented in AFNs compared to conventional food systems, groups may be disproportionately white and higher-class. Flatter hierarchies and general openness to participation, though supposed prerequisites for food justice, do not guarantee that traditional gender roles, passive exclusion, or social barriers are averted.
