CommunityBiodiversityClimate changeHealthPolicyThe 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.

2026Wendelboe-Nelson C., Lyon K., Alex E., Malden S., Williams A. J., Thompson C. W. · International Journal of Environmental Research and Public Health · 英国・スコットランド・エディンバラ
A retrospective analysis of 32 community-led climate action projects funded through the Edinburgh Communities Climate Action Network (ECCAN) and its GreenLight programme (2024–2025), spanning energy, transport, food, circular economy and green space, none with a formal health evaluation framework. Data extracted from final reports covered 3,195 direct participants. Although health was not an objective, 21 of the 32 projects (66%) reported secondary health and wellbeing outcomes. Projects with direct nature contact showed the strongest co-benefits: nine of ten high-nature-contact projects reported health benefits, against two of eight low-contact projects. Following community-garden workshops, 94% of participants reported increased willingness to engage in future community activities and 76% reported improved mental wellbeing. The authors propose a "Community-Environment-Health Nexus" (CEHN) framework for how community-led environmental action generates synergistic health co-benefits.

2026Matthias Kowasch, Pierre Metsan, Adeline Mweleul, Helena Tischler · Geo Geography and Environment · Vanuatu
This paper investigates how school gardening contributes to the re-valorization of local knowledge and the decolonization of the educational system in Vanuatu. An empirical study in five secondary schools on Efate and Tanna islands, combined with curriculum analysis and participatory observation, revealed that most students regularly work in school gardens, cultivating various crops using mixed cropping and fallow land. Students are familiar with the yam seasonal calendar, but while sustainability topics are in curricula, discussions of traditional worldviews are lacking. School gardening enhances agricultural resilience, connection to land, kastom, and food sovereignty, leading to recommendations for stronger inclusion of local knowledge, field trips, and collaboration with kastom schools.

2026Pasquale Napoletano, Maha Deeb, Sara Perl Egendorf, Brooke Singer, Zhongqi Cheng, Erika Di Iorio, Anna De Marco, Claudio Colombo, Peter Groffman · European Journal of Soil Science · Global
This study tracked the development and dynamics of organic matter pools over 21 months in constructed soils (1/3 compost, 2/3 fine glacio-fluvial sediments) with eight different vegetation treatments. Time and vegetation were the main drivers influencing soil parameters. A high diversity "All" treatment significantly enriched mineral/sand-associated organic carbon (MSOC) and nitrogen (MSON) by 15% and 12% respectively, compared to a non-vegetated "Bare" treatment. The presence of sunflower was associated with low values of nitrate-N, particulate organic N, hot-water extractable carbon, and β-glucosidase.

2026Ladislava Grochová, Marek Litzman, Veronika Solilová, Helena Dvořáčková · Frontiers in Sustainable Cities · Czechia
This study used a simulation model to assess the financial viability of temporary urban agricultural projects on brownfield sites, specifically social farming and community garden models, at the Špitálka brownfield site in Brno, Czechia. The analysis found that carbon offsets were economically marginal, but a strategic combination of labor and establishment subsidies was crucial for financial survival. The Community Garden model showed higher self-sustainability potential (BCR > 1.0), while the Social Farming model required nearly 100% subsidy to break even (NPV = 0).

2026Xiaochuan Xing, Lufei Zheng · Sustainability · Global
This study conducted a literature review and structured qualitative comparative analysis of representative urban agriculture (UA) theories across different historical periods. An analytical framework with ecological, socio-economic, technological and design, and spatial relations dimensions was used to compare theories. The research found that the ecological dimension underpins most theories, spatial relations demonstrate spatial value, design and technological innovation connect theory to urban development, and the socio-economic dimension reflects growing attention to UA. Chronological analysis revealed the evolution of UA theories from 19th-century integration to 21st-century diverse approaches.
PolicyEconomicsCommunityClimate changeCultivating together: unearthing the transformative potential of community gardening as prefigurative collective action in Ljubljana
2026Blaž Križnik, Laura Mittermaier · Local Environment · Slovenia (Ljubljana)
This study examined the Onkraj gradbišča community garden in Ljubljana to understand how community gardening enables transformative social change and how institutional support affects it. Findings showed the garden fostered inner transformation, collective leadership, community capacity building, and some scaling strategies. However, scaling up strategies were ineffective, and the absence of institutional support limited the impact on governance, suggesting the garden's transformative potential for urban sustainability transitions was limited.

2026Yu Huan, Steffen Nijhuis, Nico Tillie · Landscape and Urban Planning · Global
This study developed a landscape-informed coupling framework and content-analysis pipeline to evaluate urban agriculture policy-practice alignment in Havana, New York City, and Chongming Island. A PRISMA-ScR literature synthesis (n=3145) informed a five-domain, 40-keyword evaluation matrix applied to policy documents. Findings indicate human-centered approaches effectively address social equity and food provisioning but have limited spatial integration, while nature-based approaches advance ecological targets but underperform on participation. The landscape-informed model achieved more balanced alignment across domains, though inter-layer connectivity gaps remain.
