Claudia Rochael Oliveira · Terra Livre · Global

This article argues that while vertical farms (VFs) are often presented as indispensable for sustainable cities, their purported sustainability is difficult to achieve without structural changes to reduce social inequalities. Critiques of urban agriculture, including VFs, point to their contribution to gentrification, racialization of space, and vulnerability to real estate capital, indicating a critical finding regarding equity. The article advocates for VFs to be appropriated by social movements to foster critical stances against conventional agriculture and catalyze urban utopias.

Marie Claire Uwase, Jean de Dieu Uwimana · Zenodo (CERN European Organization for Nuclear Research) · Rwanda (Kigali)

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.

Chiara Tornaghi · · Global

This chapter, based on 15 years of research, identifies key shortcomings in urban planning policy that prevent urban agriculture from reaching its full potential for human and non-human health. These include the failure to recognize urban agriculture as food production, the invisibility of soil and its role, and the neglect of soil care and food production specialists in public land design and soil management. The chapter suggests that agroecological considerations can enhance urban agriculture's ambition in public spaces.

This study, using a systematic literature review with the PRISMA method, investigated whether distinctions between urban and rural agriculture justify "urban agriculture" as a specific category. The analysis revealed a lack of consensus among authors, with a predominant understanding that there are not two distinct types of agriculture, but rather the same activity carried out in different spaces, which questions the validity of the term "urban agriculture."

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.

Dennis Raphael · Policy Press eBooks · Canada; United Kingdom

This chapter documents the growth of charitable non-governmental responses to food insecurity in Canada and the UK, including food banks, food diversion schemes, and community gardens. It is shown that these responses are problematic as they fail to address the economic and political causes of food insecurity. Further failures associated with charitable responses include the experience of stigma and degradation by food bank users and the promulgation of the belief that food insecurity is being addressed.

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.
