A study in Mogadishu, Somalia, used snowball sampling to assess constraints and opportunities for urban horticulture. It found that temperature, wind, pests, diseases, and limited irrigation water significantly restrict production, particularly for open-field farmers who face high irrigation demands, pest infestations, and low-quality yields unattractive to buyers. While greenhouses offer some protection, plastic greenhouses specifically suffer from inadequate gutter height and poor ventilation, requiring farmers to use primitive methods to combat extreme temperatures.

In Lydiate informal settlement in peri-urban Zimbabwe, Malawian migrants mobilize insurgent practices, including informal land seizures, spiritual claims, and communal strategies, to access land for farming. Access to land for urban and peri-urban farming remains a significant hurdle, especially for marginalized migrants. Migrants invoke divine ownership narratives, Nyau cult practices, and witchcraft deterrence as tactical tools for defending seized land.

This study analyzed the environmental, social, and economic factors of agricultural production in the Buenos Aires Metropolitan Region (RMBA) across 28 municipalities, using National Agricultural Census data and an adapted ecosystem services (SE) estimation model. Findings indicated that 97.4% of small and medium-sized horticultural producers use conventional management, with only 2.6% employing non-conventional practices. Structural problems identified include informal labor, limited technical access, and urban pressure, highlighting the need for public policies to strengthen more sustainable production systems.

Christine McCullum-Gómez, Yuri Milena Castillo Quiroga, Monica Diaz-Beltran · Academia Nutrition and Dietetics · Colombia

This article describes multiple efforts to facilitate the transition to a more sustainable food system in Colombia. Public health nutrition professionals can increase food security, build food sovereignty, and facilitate this transition through community food gardening and peri-urban and urban agriculture projects, food waste reduction programs, and sustainable menu projects incorporating indigenous, native, and local foods. Such projects should be participatory and tailored to meet the needs of stakeholders in the different regions of Colombia.

A study in Accra, Ghana, investigated mosquito larval habitats and their impact on Anopheles gambiae s.l. larvae density, conducting surveys at 15 locations during 2022's dry and rainy seasons. Of 727 potential habitats, 65.34% were positive for Anopheles larvae, with drainage ditches being the most common type. Irrigated urban farming sites showed the highest abundance of An. gambiae s.l. larvae, particularly during the rainy season, indicating that urban farming contributes to increased mosquito breeding habitats.

Sumit Vij, Vishal Narain · Wiley Interdisciplinary Reviews Water · Global

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.

Abdul-Salam Ibrahim, Marney E. Isaac, Thembela Kepe · Land Use Policy · Ghana

Focusing on Ghana, where floods driven by urbanization and climate change are destabilizing urban systems in which land tenure is integral, this study drew on political ecology and land-tenure-security frameworks to examine how floods affect the land tenure security of flood victims. Based on semi-structured interviews with flood victims and planning officials, it found that flood-induced rezoning and new planning schemes, tenant insecurity, relocation, loss of land documents, and threats to urban agriculture all affect flood victims' land tenure security; possessing land documents was found to be important for tenure security but not an absolute condition for victims' perceived security. Post-flood land-use planning for flood risk management was found to have dual potential — it can enhance tenure security and bolster community resilience, but when carried out in an exclusionary way that overlooks the urban poor, it can instead perpetuate inequality and tenure insecurity. The study recommends tenure-responsive land-use planning that embeds contextual, procedural, and distributive equity principles into planning responses to urban floods.

Against a backdrop of intensifying urban heat island effects and residents' mental health problems amid urbanization, this study examined the impact of an Urban Food Forest Program on urban environmental comfort, heat island mitigation, and the mental health of middle-aged and elderly residents. Using on-site field measurements and questionnaire surveys, it analyzed the environmental comfort of green spaces in urban heat island hotspots and assessed participants' mental health. The Urban Food Forest Program significantly reduced surrounding environmental temperature, with an average cooling effect of 2.4°C particularly in soil areas, and reduced heat island intensity in the surrounding area by 15%. In the mental health survey, male participants scored significantly higher than female participants (p = 0.017), and middle-aged and elderly participants who took part more than five times per week scored 17% higher, significantly better, than low-frequency participants. The study notes that its relatively small sample size and limited observation period may affect the generalizability of its findings, and that it focused on one specific urban area that may not represent the broader urban context.

A systematic review synthesized literature on the oral bioaccessible fraction (BAF) of arsenic, cadmium, chromium, nickel, and lead in vegetables grown on contaminated soils, drawing values from multiple online databases across potentially toxic elements (PTEs), in vitro test methods, and vegetable types. The review starts from the premise that many urban and peri-urban brownfield sites carry a legacy of soil metal and metalloid contamination, so crops grown there may pose human health risks. Median PTE BAFs ranked Cd > Ni > Cr > As > Pb; among in vitro methods, the unified BARGE method (UBM) produced the highest median BAFs (63.0% gastric, 59.6% gastrointestinal); and by crop type, BAFs ranked non-vegetables (e.g., rice, fungi) > legumes > root vegetables > bulb vegetables > leafy vegetables.
