Superintendencia Nacional de Servicios de Saneamiento (SUNASS) · Superintendencia Nacional de Servicios de Saneamiento (SUNASS), Plataforma del Estado Peruano · Peru

Peru's sanitation services regulator (SUNASS) reported on 18 January 2023 that more than 635,000 people in Lima Metropolitana (6% of its population, including 180,000 children under 11) lack access to Sedapal's public drinking water network. Those without network access buy water from tanker trucks at 16-18 soles per cubic meter, up to six times the roughly 3 soles per cubic meter paid by network-connected users. SUNASS also published a district ranking of daily per-capita water consumption, with San Isidro highest at 280 liters and Lurigancho lowest at 32 liters.

Manda S. · Journal of International Development · Zambia (Chongwe, Lusaka)

This study examines how Zambia's COVID-19 'new normal' policies disrupted peri-urban food production and market access near Lusaka, finding that ~53% of small-scale farmers reported zero agricultural income and that policy responses lacked systematic agricultural support.

Harvey S., Mount P., Valentine H., Gibson C. · Journal of Agriculture, Food Systems, and Community Development, 11(4):233-247 · United States

Interviewing 12 farmers who participated in a gleaning program and 16 who did not in the Greater Kansas City metro area, this study analyses motivations for and barriers to donating surplus produce to food-rescue organisations such as food banks. Participants cited ease of donating and tax incentives; non-participants cited safety and liability concerns. It informs the design of food-rescue schemes that redirect urban and peri-urban farm surplus to community food aid.

Using mixed methods, this article traces the evolution of urban agriculture practice, support, and policy in Philadelphia and Chicago since the 1990s, contrasting cities that treat farming and gardening as public goods with those seeking economic and redevelopment gains. It finds that while both cities became prominent urban farming centers, Chicago increasingly treated urban agriculture as a public good whereas its status in Philadelphia remained contested and unstable.

Celina L. Martinez, Daisy Rosero, Tammy Thomas, Francisco Soto Mas · Health Promotion Practice · United States (New Mexico)

This qualitative study assessed how community-supported agriculture (CSA) contributes to human capital and addresses social determinants of health in central and northern New Mexico, using questionnaires with 13 purposively sampled CSAs (8 responded). The responding CSAs reported activities such as training, job creation, education, access to healthy food, food security, health education, social connections, and food justice. The authors argue public health should support CSA and generate evidence on its health and social benefits.

This research characterized commercial urban agriculture (CUA) operations in Florida, United States, and explored urban farmers' perceptions of needs, barriers, and opportunities for CUA development. A cluster analysis identified three distinct groups of urban farmers with differing perceptions of barriers, opportunities, and informational needs. The study notes that the U.S. Department of Agriculture Census of Agriculture does not report data on CUA operations, limiting knowledge about their status, including barriers to business operations and profitability.

Nehiby Alcántara Nieves, Rosa María Larroa Torres · Espiral estudios sobre Estado y sociedad · Mexico (Mexico City)

This article investigates the functions of urban gardens in Mexico City two years after the implementation of the Food Sustainability System and the Urban Garden Law. A qualitative study found that public officials tend to prioritize the environmental functions of urban gardens, while for users, the sociocultural functions are the most relevant. The research suggests that urban gardens possess environmental, economic, and sociocultural multifunctionality.

Luíza Costa Caldas, Tania Pereira Christopoulos · Revista de Gestão · Brazil (São Paulo)

This study investigated urban agriculture in São Paulo, Brazil, from the perspective of social capital, using a literature review and semi-structured interviews with participants in urban agriculture initiatives. It identified sources, effects, and challenges of social capital formation in this context. Findings include that social capital generates human capital, citizenship, engagement, resource access, and information access, but faces challenges related to homophily and the perception of benefits.

Rosangela Hespanhol, Antônio Nivaldo Hespanhol · Revista de Tecnologia & Gestão Sustentável · Brazil

A case study of urban agriculture in Álvares Machado, Brazil, identified challenges including difficulties in accessing land and water for irrigation, the absence of official technical assistance services, and a lack of public policies at national, state, and municipal levels. Despite these difficulties, urban farmers are responsible for a significant portion of leafy greens and legumes production, establishing direct relationships between producers and consumers through markets and street stalls.

K. Michelle Glowa · Journal of Agriculture Food Systems and Community Development · United States (California)

This paper reflects on the engagement between Mexican and Salvadorian farmers at the Beach Flats Garden in Santa Cruz, California, and local educational institutions. It discusses the garden's role in critical food system education, highlighting its function as a space of resistance to gentrification in a competitive land market. The garden provides examples of noncapitalist exchanges and decolonial foodways, emphasizing traditional agroecological knowledge.

Urban agriculture (UA) in Latin American countries was analyzed using an ecosystem services framework. From plant production, 17 ecosystem services, 6 benefits, 6 assets, and 6 indirect drivers were recognized. Strengths of UA were related to ecosystem services, benefits, and beneficiaries; weaknesses were related to the misuse of inputs, and human and environmental health; and threats were related to regulation, governance, and land tenure issues.

Ana Clara Aparecida Alves de Souza, Fernando Dias Lopes · Cadernos EBAPE BR · Brazil (Porto Alegre)

This article analyzes an urban collective garden, Horta da Formiga, in Porto Alegre, Brazil, through a two-year participatory investigation using Pierre Bourdieu’s framework. The study found that the more protagonists of Horta da Formiga align with capitals considered legitimate by the state, the more they can reconcile contradictions in this field. However, despite individual agency, participants face structured conditions that do not allow for more organic and diverse forms of contradiction reconciliation.

This quantitative study explored the relationship between community gardens and community vitality indicators (median household income, educational attainment, business establishment, occupied housing units) using U.S. Census Bureau data at the census tract level. While all community garden census tracts showed an increase in median household income by 2013, no direct association was found between community gardens and educational attainment. The research suggests a loose association between community gardens and increased median household income, but the garden's presence cannot be solidified as the sole reason.

Manuela Alves da Cunha, Ryzia de Cássia Vieira Cardoso · Ambiente & sociedade · Brazil (Salvador)

A descriptive study collected data from urban garden farmers in Salvador, Brazil, to assess the contribution of urban gardens to food and nutritional security and sustainable development. Urban gardens were shown to provide work and income for families, contributing to food supply and security. Beyond producing fresh vegetables for the local population, the activity also contributes to ecosystem balance and sustainability.

This research used a customized input-output model to simulate the economic impacts of Supplemental Nutrition Assistance Program (SNAP) recipients shifting food purchases from traditional retailers to direct-to-consumer venues in four US states. Both scenarios, increased outreach and financial support for SNAP use at direct-to-consumer channels, showed a positive, albeit modest, economic impact at the state level. Most increased economic activity was in the produce farming sector.

Valéria Borges Yonegura, Jennifer Domeneghini, Júlio Celso Borello Vargas, André Luiz Lopes da Silveira · LA Referencia (Red Federada de Repositorios Institucionales de Publicaciones Científicas) · Brazil (Curitiba)

This paper focuses on mobility issues in the southern region of Curitiba, Brazil. It points out that the benefits of urban agriculture, particularly the ecological advantages of short food circuits, are hindered by the isolation of its growers. The lack of accessibility in peripheral areas, due to distance or insufficient infrastructure investment, suggests a loss of opportunities in utilizing the transport system.

A social return on investment (SROI) evaluation was conducted for the 2018 growing season of the Garden Patch, an urban agriculture program of the Saskatoon Food Bank & Learning Centre in Canada. Investments in the program were valued at CA$96,474, while outcomes such as vegetables, gardening skills, health, and work/educational experiences were valued at CA$155,419. The study conservatively estimates that CA$1.61 of social value was created for every dollar invested in the Garden Patch.

Alan da Silva Vinhaes, Antônio Nivaldo Hespanhol · Revista de Geografia · Brazil (Porto Ferreira)

This study aimed to understand and analyze urban agriculture practices in Porto Ferreira, Brazil. Fieldwork, including a survey of 60 urban farmers, revealed that urban gardens promote social inclusion for low-income individuals, unemployed people, the elderly, and women. Among the surveyed farmers, 55 used their produce for self-consumption or sold it at their production sites, two sold at the market, and three sold directly to supermarkets.

Daniel Sax, Lorien Nesbitt, Shannon Hagerman · Environment and Planning E Nature and Space · Canada (Vancouver)

A case study of an urban farm in Vancouver, Canada, facing displacement due to redevelopment, revealed that urban residents engaged in urban greening can be both implicated in and impacted by green gentrification processes. The study highlighted the power dynamics farm members navigate to preserve land access and found that the farm's identity was co-opted by development agents as a branding tool. This research contributes to understanding the limitations of development processes in accounting for green gentrification risks.
