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.

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.

Andrés Barsky · · Latin America

This chapter assesses the current state of threats to and measures to protect periurban agriculture around cities in Latin America. It highlights the social and spatial vulnerability of peri-urban agriculture and its increasing appearance on Latin American food and urbanistic agendas. Examples of strategies for the concrete management of peri-urban agriculture in Latin American cities include the institutionalization of relevant organizations, the enactment of specific laws, the implementation of programs for small-scale production, and the generation of territorial intervention instruments. The conclusion argues for the need to generate new public intervention instruments to preserve and design spaces of high productive and environmental value in periurban areas.

Sofía Aguado, Helena Cotler, Marta Astier, Alejandro Padilla‐Rivera · Circular Economy and Sustainability · Latin America

This literature review examined methodologies applicable to municipal composting systems linked to urban agricultural production, with a specific focus on the Latin American context. It revealed a lack of structured methodologies to assess the circularity of municipal organic waste management systems and their connection with urban agriculture, particularly in heterogeneous contexts like Latin American cities, despite numerous existing evaluation methods. Life Cycle Assessment (LCA) is commonly used but often prioritizes environmental impacts, neglecting social, economic, and circularity dimensions.

Sullivan, Miriam Caroline · DigitalCommons - CalPoly (California State Polytechnic University) · United States

This project explores how urban planners can create regional food equity, defined by six dimensions: nutritional adequacy, affordability, cultural relevance, social and spatial equity, and popular agency in the food system. It includes a research paper on historic context, current trends, and case studies, followed by guidance for policy and plan creation. The project also analyzes three food systems plans—San Diego (2024), Chicago (2010), and Austin-Travis County (2024)—evaluating them against the outlined criteria, and delves into urban agriculture and community gardens as methods for improving regional food equity.

An exploratory survey (N=401, n=144) was conducted to assess food waste patterns among consumers involved in Community Supported Agriculture (CSA) initiatives in the Central Urban Core of Curitiba, Brazil. The results showed that participation in CSAs does not significantly influence consumer behavior regarding food waste. This indicates a need for sustainable consumption education and context-specific solutions.

Junyi Hua, H. Allen Klaiber, Douglas H. Wrenn · Journal of Environmental Quality · United States (Chesapeake Bay)

This study developed a micro-level Ricardian model to assess how long-run climate patterns affect agricultural land values across the urban-rural gradient in the Chesapeake Bay Watershed. Analysis using an 8-km gridded dataset combining farmland prices, high-resolution climate data, and urban land cover showed that seasonal temperature and precipitation nonlinearly affect land values, and urbanization significantly moderates precipitation effects. A climate simulation suggested heterogeneous impacts across urban grids.

The study aimed to characterize the productive, commercial, and sociocultural aspects related to organic vegetable production and commercialization, identifying main marketing channels and understanding difficulties faced by producers. It concluded that organic production, combined with collective organization and the strengthening of the solidarity economy, represents a viable alternative for a more just, sustainable, and female-led rural development model.

Qing Zhong, Daoqin Tong, Courtney Crosson, Yinan Zhang, Rashi Bhushan · Water Resources Research · United States

This study developed a spatial optimization model to identify investment strategies for deploying rainwater harvesting (RWH) and reclaimed water systems to expand urban food production in water-stressed cities. Applied to Tucson, Arizona, the model showed that 72%–96% of investment was allocated to rainwater tanks, though RWH contributed only 18%–27% of total food production. The results indicated that expanding the reclaimed water network was more effective and cost-efficient for urban food production compared to implementing rainwater tanks.

Belma Soto-Fernández, Lurys Bourdett-Stanziola · Asian Journal of Agricultural and Horticultural Research · Latin America

A documentary review on the importance of urban gardening in Latin America revealed that urban gardening, when approached through the lens of agrobiodiversity, has become a key strategy for safe food production and environmental sustainability. However, it was found that several Latin American countries lack clear and established laws to regulate this activity. Preliminary evidence of rotavirus was detected in fresh vegetables from an urban garden in Panama, indicating that urban gardens can become infection foci capable of causing diseases of public health and veterinary importance.
