This article develops a theoretical framework to analyze how digital land registries in Rwanda, specifically in Kigali's peri-urban areas, mediate women's access to formal agricultural credit. The framework posits that despite formal legal equality, digitization can paradoxically solidify existing patriarchal biases within credit assessment algorithms. It reveals that digital land governance is not a neutral solution for gendered credit gaps and can entrench barriers to women's financial inclusion in peri-urban agriculture by systematically undervaluing women's communal land use practices as collateral.

Vazoumana Koné · Uirtus · Côte d’Ivoire

In Abidjan, Côte d’Ivoire, market gardening is widespread, but the Master Plan of Greater Abidjan does not allocate specific spaces for these crops. This forces producers to use unsuitable areas like flood-prone lowlands. A study of 45 market gardeners found that they employ various social practices to legitimize their activities and maintain their presence in urban spaces despite the lack of official land allocation.

Peter Nixon, Anu Ramaswami · Environmental Research Letters · United States

This paper quantifies environmental benefits and disbenefits from various vegetable farming localization scenarios across 378 US metropolitan areas. While scenarios found few significant land constraints and revealed net environmental benefits to groundwater overdraft and fertilizer-related PM2.5 emissions in 11%–55% of metros, the model also revealed where relocalization would exacerbate existing environmental vulnerabilities. This indicates potential environmental tradeoffs depending on the location.

Katuka, Stephen Agire, Magaji, Sule, Ismail, Yahaya · Zenodo (CERN European Organization for Nuclear Research) · Nigeria (Abuja)

This study analyzed the impact of rising food prices on the food security of different socio-economic groups in Abuja, Nigeria, using a cross-sectional survey of 400 households. Findings revealed that only 18% of households were food secure, while 56% experienced moderate to severe food insecurity. Food price inflation had a significant negative effect on food security, particularly among low-income households. Rising food prices were shown to increase the likelihood of mild, moderate, and severe food insecurity by 53%, 88%, and 132%, respectively.

José Arturo Méndez Espinoza, Martín Neri-Suárez, Karen Italia Ruiz-López · LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas) · Mexico (Puebla)

A case study in Cuautlancingo, Puebla, Mexico, revealed an adverse context for the reproduction of peri-urban family farming. Urban expansion, neoliberal policies, and real-estate speculation have displaced traditional agricultural practices and fostered land-tenure changes. Between 2005 and 2021, over 40% of agricultural areas were lost due to industrial and housing growth. The study concludes that without effective protection and territorial planning, peri-urban agriculture in Cuautlancingo is at risk of disappearing under urban and industrial pressures, with implications for local food security.

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.
