This review examines the multifunctionality of urban agriculture globally and details the case of São Luís, Brazil. In São Luís, agricultural production has low expression in municipal GDP, with producers facing challenges such as small production areas, a need for technical assistance, and poor transport conditions. The study found a lack of public support for urban farmers in São Luís, contrasting with successful urban agriculture experiences that benefit from converging public policies.

This study analyzed technical-productive and socioeconomic limitations to urban agriculture adoption among members of the Network of Urban and Periurban Agriculture (RAUP) in Xalapa, Veracruz, Mexico. Researchers applied 25 questionnaires to active members and 10 to non-practicing participants. Both groups of RAUP participants identified socioeconomic factors, such as lack of space and limited free time due to urban lifestyles, as the main constraints, while technical-productive limitations were not considered relevant.

This chapter analyzes the impact of two peri-urban agricultural policies: Ontario’s Greenbelt in Canada and the InterSCoT in Toulouse, France, both aiming to regulate urban sprawl and preserve peri-urban agriculture. Ontario’s Greenbelt is a top-down zoning policy, while Toulouse’s InterSCoT results from municipal coordination. Based on farmer in-depth interviews, the study found that preserving farmland alone is insufficient to maintain a sustainable peri-urban farming sector, emphasizing the need for coordination spaces that include farmers' needs during policy design.

This article demonstrates urban and peri-urban agricultural practices in small backyards, remnant residential garden areas, and green roofs. These practices aim to produce food for self-consumption and to foster farming among neighbors for subsistence or as a source of supplementary family income.

Antonis Vradis, Timo Bartholl · Journal of the British Academy · Brazil (São Paulo)

This article discusses urban food insecurity and the right to the city in Brazil, specifically in the Maré complex of favelas in Rio de Janeiro. An action-research approach was deployed to study food insecurity, situated in the context of increasing securitization in Brazilian urban peripheries and the ensuing obstacles to populations' right to the city. The article proposes the agroecological approach as a potential avenue to achieve popular food sovereignty in these urban peripheries of the Global South.

Its aim is to propose sustainable alternatives for providing healthy food produced in small spaces.

Leandro Pessoa Lucena, Cláudio Eurico Seibert Fernandes da Silva · Revista Ibero-Americana de Ciências Ambientais · Singapore; Brazil (Cuiabá)

This descriptive and exploratory study compared urban agriculture models for food security in Singapore and Brazil (represented by Cuiabá/MT), using photographic records and testimonies. Preliminary results showed significant differences: Brazilian urban agriculture was incipient, small-scale, and lacked quality and technological capacity, targeting areas of extreme poverty. In contrast, Singapore's urban agriculture was consolidated in various highly productive, technologically advanced formats, including vertical and rooftop farms, demonstrating environmental and social welfare concerns.

David Ceaser · Agritecture · United States

In this December 7, 2018 article for Agritecture, horticultural consultant David Ceaser reports on the challenges facing agrihood development, using The Cannery in Davis, California (500+ homes, 150 acres, with a 7.4-acre organic farm) as a case study. He notes that residents held unrealistic expectations about how the farm would be run and their role in it, and that poorer-than-expected soil quality required amending with organic matter, delaying farm development. Farm Director Sri Sethuratnam described the aging farmer population and food-production challenges as "a national security issue."

This dissertation addresses agricultural extensification from several angles. Chapter 1's literature review showed an increase in research on urban and peri-urban agriculture (UPA) and ecosystem services, but highlighted a need for quantifying ecosystem services and functions to clarify ecological tradeoffs. Subsequent chapters focused on a mixed-methods study in New Hampshire, surveying approximately 600 residents (494 general population, 103 food system stakeholders) on their perception of forestland conversion to agriculture.

Cupuaçu is important for family and peri-urban agriculture and indigenous communities in the Amazon, contributing to local food security. This study aimed to characterize pulps from cupuaçu plants with varying susceptibility to witch's broom disease. Differences were observed mainly in chemical and physical-chemical characteristics among pulps, with emphasis on susceptible and highly susceptible plants. All evaluated pulps complied with established quality standards, but significant differences were found between physicochemical characteristics, proportional to the plants' susceptibility to witch's broom disease, particularly for soluble solids (SS) and titratable acidity (AT).

A Brazilian thesis aims to trace the evolution and worldwide spread of urban agriculture (AU), build a framework for identifying its forms, and present a local case from southern Brazil. The interdisciplinary, exploratory, qualitative study combines a PRISMA-protocol systematic review with a multi-case study in the Porto Alegre metropolitan region. It finds that AU can take multiple formats depending on the domain, people and interests involved, and that in the municipality of Porto Alegre certain categories are more used than others because of local support schemes. Part of the studied initiatives were initially community-centered but transformed over time into businesses seeking new market opportunities. The AU-related terms found in the literature were summarized into a framework linking them to their sub-levels.

Separately collected urine is presented as an attractive potential fertilizer because of its high nutrient content, low cost, and inherent link between urban wastewater management and peri-urban agriculture. Urine from waterless urinals was applied to corn and lettuce to examine the impact of application rate and frequency on plant growth and soil parameters; in both crops, urine application significantly (p < 0.05) increased growth and leaf production relative to control plants. More frequent applications led to lower soil cation exchange capacity for corn and higher soil nitrogen content for both crops. Preliminary implementation calculations suggest that installing waterless urinals at the University of São Paulo's School of Arts, Sciences, and Humanities campus could save over 1,500 m³ of water and produce 360 m³ of urine annually; these experimental and modeling results are discussed in the context of scaling up urban urine collection, transport, and fertilization in São Paulo, Brazil.
