This study grew seven genotypes of Hibiscus sabdariffa L. in green roof, field row, and high tunnel systems in and near Washington, DC, to compare leaf and flower yield, nutritional differences, and insect pest susceptibility. Genotype PI 286316 produced abundant flowers, particularly in high tunnels, while leaf production was highest in field rows despite frequent Popillia japonica attacks. PI 273388, PI 275414, and green hibiscus yielded the most leaves, and genotypes showed nutrient differences regardless of the production system. The locally adapted green hibiscus performed well across systems, was least attacked by pests, and had higher nutrient levels, demonstrating H. sabdariffa's suitability for temperate urban systems.

Anna Kapała · Comparative Law Review · United States

This study analyzed federal, state, and local regulations in US law to identify instruments supporting local food systems (LFS), including food safety, zoning, tax law, and federal programs. It found that US law lacks a systematic approach to LFS support, but identified legislative tools such as food safety exemptions, sales tax exemptions, local zoning laws for urban agriculture, and federal grant programs.

This study describes an Extension-Community partnership that designed learning environments to support elementary students experiencing chronic stress in the United States. The intervention included creating a calming room, building a community garden on school grounds, and providing educational programming for teachers, staff, and families. Interviews with 20 teachers and school staff revealed the program's success in supporting positive outcomes for students, staff, the school, and the surrounding community.

Rafael Carvalho Machado, Sieglinde Kindl Da Cunha · Waste Management & Research The Journal for a Sustainable Circular Economy · Brazil (Curitiba)

This study investigated Curitiba, Brazil's Urban Agriculture Program (UAP) and its decentralized composting strategy, which aimed to close the agricultural loop within city bounds. Despite training 24 urban farmer communities in composting techniques, the program was unable to achieve this goal. The research, based on secondary data review, interviews, and participatory observation, identified cultural barriers and conflicts among actor roles within the UAP that hindered the adoption of composting practices.

Stephanie Buechler, Karina Guadalupe Martínez-Molina · Energy and Climate Change · United States

This study compared rural and urban populations living near or receiving energy from a large-scale solar-wind energy park in Arizona, Southwest U.S., using an energy justice framework. Small-scale renewable energy projects better served low-income groups, with more governmental and non-profit organization support for these projects in urban areas. Adverse effects of large-scale projects on communities and wildlife were not being addressed via benefits or profit sharing.

Irrigation evaluations were performed for 24 urban and small farms in Cache Valley, Utah, during the 2015 growing season, providing a clearer picture of urban and small farm agricultural irrigation. Irrigation efficiencies ranged from 6% to 100%, showing high heterogeneity, with small fields generally having greater irrigation depths and surface irrigated fields applying higher depths than sprinkle and drip irrigated fields. Management significantly influenced efficiency, and water conservation programs may not result in true water savings if management effects are ignored.

A community garden with medicinal herbs serves as an excellent tool for study and environmental awareness for students involved in the project and the wider academic community, as well as for internal and external communities utilizing the accessible herbs. In this project, beds with various medicinal herbs, including ora-pro-nobis, mint, basil, horsetail, boldo, alfavaca, aloe vera, lemon balm, and lemongrass, were created and maintained. The project aims not only to provide natural treatment to the community but also, importantly, to raise awareness about the harms that excessive use of allopathic medicines can cause to metabolism.

Mariana Castañeda Díez, Rita de Cássia Martins Montezuma · Sociedade & natureza · Brazil (Rio de Janeiro)

This paper addresses two problems in Rio de Janeiro: environmental issues from native restinga fragmentation due to urban development, and food shortages in low-income communities. It proposes edible landscaping for public spaces on Rio's west side to tackle these issues. The research involved theoretical framework analyses, geo-technological tools, and local visits for biophysical, urban, and architectural analyses to select suitable public spaces for the edible landscape proposal.

This article analyzed the feasibility of implementing urban agriculture (UA) on idle land within the Tarumã – Ponta Negra Environmental Protection Area in Manaus, Brazil, as a tool for territorial governance and urban planning. Semi-structured interviews and card sorting techniques were applied to the target population. The study found that the use of idle land for UA is not envisioned as a territorial governance instrument, a situation exacerbated by municipal authorities hindering the legitimization of bills for such land use.

Angélica Campos Nakamura, Valéria de Marcos · Estudos Avançados · Brazil (São Paulo)

Since the 2000s, urban and peri-urban agriculture activities have gained momentum in São Paulo, Brazil, directly impacting the city's agricultural sector. In the far south, public authorities, the University of São Paulo, and several NGOs promoted agroecological practices, leading to the establishment of Cooperapas, São Paulo's only farmers' cooperative. This expanded the production and commercialization of agroecological foods for the city.

Helda Morales, Bruce G. Ferguson, Kimberly Chung, Ronald Nigh · Desenvolvimento e Meio Ambiente · Mexico (Chiapas)

This study explored the potential and limitations for agroecological scaling through formal educational structures, using the LabVida school gardens program in Chiapas, Mexico as a case study. Through training, educators gained an appreciation of agroecology and applied practices in their school gardens, although their understanding of agroecological principles and scientific process remained limited. The program's greatest impact was on educators’ eating habits and their perception of the value of local knowledge and its relevance to schoolwork.

This study in Baltimore, Maryland, used GIS mapping and spatial analysis to assess the proximity of urban farms to environmental hazards, including those with heavy metal contamination. Analyses indicated that contamination of urban farms is a possibility due to proximity: more environmental hazards were found in census tracts with urban farms, and low-income communities of color had hazards near urban farms. Historically industrial areas showed a higher concentration of environmental hazards with heavy metal or unknown contamination.

This study in Baltimore, Maryland, used GIS mapping and hotspot analysis to assess the proximity of urban farms to environmental hazards. Most urban farms were located in low-income communities of color. However, most environmental hazards were not near urban farms but in predominantly White areas or historical industrial centers. Despite a generally low risk of contamination, some urban farms in low-income and Black/African American communities were potentially contaminated by hazardous sites.

Farmers’ markets, Community Supported Agriculture (CSA) programs, and community gardens, while aiming to help low-income families access fresh produce, often assist more middle-class families. In Utah, these programs could be improved, as the state does not utilize the WIC Farmers’ Market Nutrition Program or accept WIC Cash Value Vouchers, and has few Farm to School Programs.

Manuela Maluf Santos, Paulo Eduardo Moruzzi Marques · Estudos Avançados · Brazil (São Paulo)

This article conceptually explores the "locavorism" food activism movement, noting that its practical application can have diverse and even antagonistic effects. To analyze these contradictions, two farmer organizations in São Paulo involved in local consumption circuits were interviewed to understand the potential social and environmental effects of this purchasing model. The abstract does not present the findings of these interviews.

Ana Júlia Maia Mairink, Alice Menezes Monteiro, Rejane Magiag Loura, Tiago Almeida Nogueira · · Brazil (Belo Horizonte)

This study provided academic and technical support for designing low-environmental-impact solutions to infrastructure deficiencies at the "Coqueiro Verde" Collective/Community Urban Agriculture Production Unit in Belo Horizonte, Brazil, to develop urban resilience strategies. A participatory diagnosis identified problems such as water scarcity and mismanagement, lack of sanitation, and the need for easy implementation and low cost. Primary solutions selected were the dimensioning of an Evapotranspiration Tank and the modular design of a support point based on soil-cement blocks.

Rebecca Amato · Amsterdam University Press eBooks · United States (New York City)

This chapter discusses the historical production and perception of "empty space" in New York City, from settler colonialism to gentrification, driven by techniques like filtering and declaring vacancy. It highlights how the acceleration of development to maintain world city status threatens alternative visions like cooperative centers and community gardens. These alternative uses are presented as models for inclusive cities, despite being under threat.
