This systematic review analyzed 363 community garden (CG) articles from 1992 to 2021, identified through a bibliometric analysis of 1534 urban agriculture (UA) and 470 CG studies. Findings indicate that UA research primarily focuses on food production, while CG studies emphasize social and urban dynamics, mainly in the Global North, with limited quantitative evidence of their impacts. The review concludes that CGs contribute to all SDGs, but their roles in urban resilience, food systems, and policymaking are underexplored, and their overall contribution to sustainability remains unclear due to the lack of a global estimate.

This review addresses a knowledge gap on how peri-urban residents in Asia and Africa adapt to the impacts of urbanization and climate change on water security. As rural-urban boundaries rapidly blur in the global South, peri-urban spaces are characterized by weakening access to water resources, depleting common property institutions and poor civic engagement, and the review presents the persistent marginalization of peri-urban residents from a water security perspective, while also showing that they do develop adaptation measures. Existing literature is found to focus primarily on (1) increased vulnerability of peri-urban agriculture and allied sectors, (2) barriers and enablers to water-security-related adaptation planning, and (3) justice in peri-urban areas, and the review calls for further study of emerging cooperation and collective action that could reduce conflicts between peri-urban and urban inhabitants and improve water security.

A life cycle assessment (LCA) comparing the environmental performance of a conventional ceramic roof (CR) and a modular green roof (GR) planted with the edible species Pereskia aculeata. Primary data came from experimental GR prototypes monitored for one year, including irrigation volumes, plant development and rainwater retention across 50 rainfall events; secondary data were modeled from the ecoinvent database and literature. The analysis had three stages: comparing CR and GR construction and first-year use, sensitivity/uncertainty analysis of alternative GR materials, and a 30-year projection of use-phase impacts. In stage one, GR outperformed CR in 11 of 14 impact categories, with total normalized impacts 13% lower; 80% of CR's impact came from ceramic tile production, while in GR polymer components dominated, with polypropylene accounting for 82% of fossil depletion and polyester for 95% of ozone depletion. Substituting alternative polymers for the module and filter layers cut marine and freshwater ecotoxicity by over 70%. The optimized GR scenario had 71% lower normalized impacts than CR and outperformed it in 13 of 14 categories, with the 30-year projection confirming GR's continued advantage.

A 2025 study in the Journal of Sustainable Development Law and Policy used Onaiza, a low-rise mixed-use residential neighbourhood on Qatar's western coast representative of suburban Doha, as a case study to examine how urban agriculture could be integrated into land use policy as a climate-change mitigation strategy in Doha Municipality. Drawing on a literature review, examination of successful case studies, and expert interviews, it identified challenges and potential for permitting urban agriculture as a land use, then produced a design proposal amending land use policy through urban planning simulations, subsidies and other incentives. It starts from the premise that food systems, food security and urban agriculture are not yet well positioned within Qatar's existing land use policy, despite the country's vulnerability to food imports and to climate change.
