This article analyzes the urban and peri-urban agriculture (UPA) in Macapá, Amapá, Brazil, focusing on existing commercialization channels to identify the relationship between urban food production and city supply. The study aimed to pinpoint difficulties, limitations, and expansion capacity of UPA. It concludes that despite a diversity of accessible channels for UPA, short commercialization channels like direct sales and open-air markets remain the primary outlets for production, indicating challenges in expanding commercialization beyond these traditional methods.

This study examined the effects of urban agroforestry on climate elements in Presidente Prudente, Brazil, hypothesising that vegetation cover combined with urban agriculture positively influences urban climate dynamics. Automatic sensors recorded temperature and relative humidity at three points with distinct land cover -- a densely built urban area, an urban area with vegetation/agroforestry, and a rural point -- during representative wet (February) and dry (July) months of 2021, with space-time panels and rhythmic analysis graphs used to identify urban heat island (UHI) occurrence day and night. It found that low rainfall combined with high wind-direction variability and speed in February produced greater UHI intensity and magnitude both day and night, while July's low wind speed, low directional variation, near-zero rainfall and stable atmospheric conditions produced more homogeneous daytime UHI but heterogeneous, high-intensity nighttime UHI.

Loudoun County · Loudoun County, Virginia · United States

Section 7.02 (Open Space) of the Loudoun County, Virginia zoning ordinance sets required open-space percentages by zoning district. In the Transition Policy Area, the TR-3UBF/LF, TR-1, and TR-2 districts require 50% open space, while TR-10 and TR-3LBR require 70%; in each of these districts, "Agricultural" use is one of the eligible open-space categories, conditioned on protection by a permanent conservation easement. Developments of five or more dwelling units must also provide at least 5,000 square feet of active recreation open space.

This study described the conditions of 60 peri-urban farmers in Mexico City working with agroecological schemes, analyzing the role of social and cultural capital in consolidating their projects and consumer links. Based on field visits and interviews, the research argued that the social and cultural capital of production units are key elements in determining the viability of the agroecological transition.

Pablo Torres Lima, Kristen Conway-Gómez, Karla Almanza-Rodríguez · Frontiers in Sustainable Cities · Mexico (Mexico City)

This study examined local community involvement in governance processes in Milpa Alta, a peri-urban agricultural area of Mexico City, using surveys, interviews, and participatory workshops. It found that Milpa Alta lacks integral adaptive capacity to address urban pressures, environmental deterioration, and agricultural dynamics. Limited participation, low local organizational levels, and distrust of government institutions hinder effective governance, indicating that a "local is not enough" approach is insufficient for adaptive governance in this peri-urban context.

This study aimed to explore the productive, commercial, and management strategies of small-scale vegetable growers in the Santiago Metropolitan Region (SMR) of Chile, their attitudes towards their activity, and to identify different profiles. A survey was conducted in person with 170 farmers, and the data was analyzed using descriptive and multivariate techniques. Results suggest that different characteristics and strategies are concomitant with certain attitudes that vegetable growers hold towards key aspects such as innovation or willingness to associate.

André Torre, Brenno Fonseca · Sociologia Ruralis · Brazil (São Paulo)

A study on the development of peri-urban agriculture in the São Paulo Metropolitan Region, Brazil, was conducted based on expert interviews, analysis of the regional daily press, and local information sites and blogs. It was found that territorial opposition between different land uses is one of the main factors preventing food production in urban and peri-urban areas. The study investigated local conflicts, their location, their link to agriculture, the consumption of agricultural soils, and the typology of opponents and supporters of this activity.

This preliminary study conducted a socioeconomic analysis of peri-urban family production of organic lettuce in Dom Pedrito-RS, Brazil, using case study techniques focusing on two family farmers. Through in-depth interviews and farm visits, it was found that production relied solely on family labor with minimal chemical inputs, characterizing a transition to organic production. Despite strong competition from large distribution networks, producing and marketing organic lettuce was concluded to be profitable, constituting an alternative income source and job creation in family farming, and assisting in transforming unoccupied spaces into productive ones.

This study investigated the role of cooperativism as an element for strengthening urban and peri-urban agriculture (AUP) in Brazil. Findings revealed that the absence of public policies and credit availability are limiting factors for AUP. Increased production and product outflow are also difficulties faced by these farmers, which could potentially be resolved through cooperation.

A paper examining the interactions between peripheralization, vulnerabilities of agricultural livelihoods, and local collective agency in creating new capabilities in intermediate Mexican cities, based on a study in Tarímbaro municipality, part of the intermediate city of Morelia. The unit of analysis was the ejido, a form of social land tenure granted to landless peasants in 1917 after the Mexican Revolution and one of the most important forms of social organization in rural Mexico; about half of Mexican territory comprises more than 30,000 community-based land tenures, mainly ejidos, and a high proportion of land now occupied by urban centres was formerly ejido land. The study used the example of 15 ejidos notably affected by the expansion of Morelia, conducting semi-structured interviews with each ejido's president in 2015, followed by a survey of 61 individuals from 11 of the 15 ejidos. The peripheralization of Morelia was found to have produced inequalities in the adjacent municipality of Tarímbaro, with differential vulnerabilities in peri-urban agricultural livelihoods found among the participating ejidos; not all ejidos succeeded in addressing vulnerabilities linked to the urbanization of agricultural land, but those that achieved some success shared characteristics that reinforced common values and motivations toward shared goals for sustaining local livelihoods. The paper highlights the importance of functional rural organizations in regulating access to, and distribution of, resources in the peripheries of intermediate cities.

This empirical study analyzed the socio-spatial development of Urban and Peri-urban Agriculture (AUP) in Fortaleza, Ceará, Brazil, examining both spontaneous agricultural activities and municipal institutional actions. While AUP holds significant relevance in the city, particularly in peripheral areas, governmental initiatives were found to be sporadic and discontinuous, lacking a broader institutional agenda. The study concluded that despite recent municipal efforts, legal and institutional support for AUP remains weak, leading to the rapid disappearance of productive spaces and indicating that institutional actions have not effectively fostered the socio-spatial development of spontaneous initiatives.

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.

This study in the U.S. Intermountain West assessed eight tree species for their suitability as windbreaks for urban farms, focusing on initial establishment and use at the urban–agriculture interface. Standard poplar and 'Theves' columnar poplar were most effective for rapid establishment. However, species with moderate growth rates like aspen, juniper, and hackberry may offer lower long-term maintenance costs for the region's challenging environmental conditions.

This study argues that urban and peri-urban agriculture (UPA), along with intra-urban open spaces, constitutes a "second best" land use for 21st-century cities pursuing sustainable growth aligned with the 2030 Sustainable Development Goals — whether through FAO's Greener Cities Strategy, which promotes garden-based UPA against poverty and food insecurity, or through UPA absorbed by city expansion, much of it commercial in nature. Based on analysis of official statistics and fieldwork in the Ejido Tejalpa in Cuernavaca, Morelos, Mexico, the study finds that UPA persists there due to its historical trajectory and access to water and land, existing in commercial form rather than as urban gardens, but not without problems. Its main threat is identified as excessive urbanization and generational change among producers, and its main challenge as achieving greater involvement of urban governments through land management and urban planning, following the experience of other countries where agriculture is given more weight in metropolitan planning.

A 2020 "On diseño" award jury statement assessed the CH-REURBANO project in the historic center of Mexico City. Three previously separate, abandoned buildings with differential foundation settlement were structurally unified by removing their central mass to create a shared courtyard that also functions as circulation and ventilation. The mixed-use program was legally justified by citing the buildings' prior history of varied uses in a zone where such mixing is normally restricted.
