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 study, conducted in Curitiba, Brazil, and its metropolitan area, aimed to discuss the risks and benefits of legalizing urban poultry farming. Through interviews with key informants, challenges were identified across sanitary, legislative, and commercial areas, urban chicken breeders, and bird management. The main challenges cited were sanitary and environmental risks, mistreatment, irregular slaughter, and neighborhood disturbances, which could be addressed through activity regulation, registration of farms, technical monitoring, and implementation of pilot projects.

This study examined school garden prevalence in 148 K-12 schools across four low-income New Jersey cities between 2010-2011 and 2017-2018, before and after the Healthy Hunger-Free Kids Act (HHFKA) of 2010. Garden prevalence increased from 19% in 2010-2011 to 32% in 2013-2014, but this increase was not sustained over time. Furthermore, schools with a majority Hispanic student enrollment had approximately half the odds of having a garden compared to schools with a majority Black student enrollment.

This study investigated the impacts of 35 years of urban expansion in Brazil's Administrative Region of Ribeirão Preto, linking it to agricultural land loss and environmental consequences. Using Landsat images and GIS, the research found rural area losses exceeding 350 km2, with equivalent production and economic losses of approximately 1.1 Mton/year and 230 MR$/year. Significant environmental impacts included the destruction of over 9100 km of natural watercourses, nearly 630 km2 of Permanent Preservation Areas, and the occupation of Guarani Aquifer recharge areas with impermeable surfaces, affecting approximately 7000 headwaters.

This study interviewed 63 urban farmers in Curuçambá, Belém Metropolitan Region, Brazil, analyzing business management and entrepreneurial skills amidst urbanization and crime risks. It found that 98.41% of businesses are family-managed, but 52.38% have little management experience, with 76.19% never keeping financial records and 81.71% never seeking technical assistance. A significant 33.33% of farmers rated criminality as "very high" severity, indicating that a lack of public safety severely limits commercial performance and investment in urban agriculture.

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.

This paper explores how urban farming in Atlanta, Georgia, shows evidence of neoliberal shaping and retooling. Through qualitative analysis, including a case study, interviews with farmers, participant observation, and archival data collection, it examines how the city and the farm are understood from the perspective of the farmer to understand the degree to which these contestations are resisting neoliberalism. The research suggests that while urban farming can provide spaces for contestation to neoliberalism, scholars should more fully consider the hybridized nature in which urban farmers understand their work.

In April 2021, a panel discussion on food security in Canada took place during the COVID-19 pandemic. This article aims to make visible the vulnerabilities and structural injustices embedded within Canadian foodscapes through different perspectives on food security and justice. COVID-19 rendered many of the structural injustices of food security in Canada more visible.

This paper introduces "impermaculture," a model of urban agriculture where farmers in cities like Portland, Oregon, embrace the impermanence of their operations, viewing the potential for displacement by higher-value developments as an intended modus operandi. This approach, utilizing portable growing systems, is presented as a means of stabilizing the "sustainability fix" in neoliberal cities. The study suggests that this 'impermaculture by design' shores up and temporally rescales the sustainability fix, providing stability to urban agriculture initiatives despite their temporary nature.

This study examined perspectives on food access among 53 low-income families with children participating in a cost-offset community-supported agriculture (CO-CSA) program across nine communities in the US states of New York, North Carolina, Washington, and Vermont. Focus groups revealed that while produce quantity was abundant and affordability was generally good, payment timing was a barrier for some, and unfamiliar foods and quick spoilage hindered acceptability. The study concluded that CO-CSA may facilitate increased access to fruits and vegetables, but perceptions of positive diet change may be limited by challenges in incorporating share pick-up into regular travel patterns and meal planning, with food waste concerns being particularly acute for families with constrained resources.

This systematic scoping review revealed the extent of existing knowledge regarding the governance and management of urban grassroots agri-food organizations in Canada. Among Canadian studies, 15 were qualitative case studies, 11 were exploration/analysis papers, one was a literature review, and one was a quantitative analysis. It was found that for greater success in urban agriculture, municipal policymakers need to intentionally and radically shift policy to plan for and integrate urban agriculture networks into the urban environment without taking over the networks themselves. The review also indicated a lack of broad research into the influence of gender dynamics on the organization and management of urban agriculture or community gardens.

This study used qualitative research methods to explore the main barriers to urban agriculture as perceived by community-based groups in Victoria, British Columbia. Data from 18 semi-structured interviews and two community mapping workshops with residents, government officials, and non-governmental groups revealed "urban agriculture zones" and "garden-style" apartment housing as important avenues. However, progress towards far-reaching changes requires an efficient urban agriculture development process, including creating site inventories, increasing stakeholder participation, reducing waitlists, and tackling high land prices.

This paper uses the Rainbow Community Garden in Winnipeg as a case study to discuss the benefits and challenges of community gardening for new immigrant and refugee families. Through a literature review and interviews with gardeners, the study emphasizes the role of food and community gardens in facilitating cross-cultural interactions, providing culturally appropriate food, and expressing cultural identity. The main conclusion is that for new immigrant and refugee participation, a garden is not only physical soil but also an important place for practicing culture and engaging in meaningful cross-cultural interaction beneficial for adjusting to a new life in Canada.

This study evaluated portable X-ray fluorescence (pXRF) measurements of macronutrients, micronutrients, and toxic elements (As, Pb) in soils and plants from 10 urban community gardens across the eastern United States. It found that pXRF and traditional methods provided agreeable estimates for some elements (Mn, Cu, Zn, Pb) but not for macronutrients (Ca, K, P). While pXRF is an accurate tool for screening Mn, Cu, Zn, and Pb, macronutrients were poorly estimated in fruits, leaves, and roots, and genus-specific and garden-specific factors may be important for plant uptake models.

This two-year participatory investigation of Horta da Formiga, a collective urban garden in Porto Alegre, Brazil, analyzed how key agents reconcile inherent contradictions. The study found that while individuals exhibit agency, structured conditions within the social field prevent the organic and diverse reconciliation of contradictions. This occurs despite agents aligning with state-legitimized capital.

This study aimed to identify and characterize different categories of urban agriculture practitioners in Curitiba. A descriptive study using bibliographic and documentary analysis found that urban agriculture activities are concentrated in peripheral areas of the city, with most participants having a monthly family income of up to two minimum wages. Despite a wide range of actors engaging in these practices, their visibility and inclusion in the political agenda occur asymmetrically.

A study of Apple Creek, Wisconsin (119 km²), a Great Lakes tributary like many others subject to Total Maximum Daily Load (TMDL) targets requiring reductions of 51.2% in suspended sediment and 64.2% in total phosphorus. From August 2017 to October 2018, an integrated stream sediment budget and fingerprinting study quantified upland and stream-corridor sources of suspended sediment and sediment-bound phosphorus. Phosphorus concentrations varied among source groups and fluvial sediment types, with higher concentrations in suspended sediment and cropland soils. Eroding streambanks accounted for 100% of the TMDL model's (SWAT) suspended sediment load but only 20% of the total phosphorus load; fine-grained streambed sediment equated to roughly three years of modelled suspended sediment load but only one-third of the total phosphorus load. The two primary sources of fine-grained streambed sediment were streambanks and cropland, with the relative streambank contribution increasing downstream and with watershed area. The relative proportion of suspended sediment varied by season and streamflow, but weighted for representative streamflow, cropland and streambank erosion accounted for 54% and 23% of suspended sediment respectively. Urban land was a source in the upper watershed, but its signature was sequestered by a mid-watershed detention basin, and contributions from construction sites were higher in fall 2018, likely corresponding to increased activity following a wet spring.

This study discussed the main environmental services and disservices associated with urban and peri-urban agriculture (UPA) in São Paulo, Brazil, using a systematic literature review and spatial analysis. It identified 12 environmental services and 5 disservices, mapping 197 UPA initiatives. The research concluded that UPA has the potential to offer environmental benefits, but can also exert negative pressures on the environment, including in areas that should be protected.

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 used optimization techniques to assess the land area and radius needed around Chicago, Illinois, to meet nutritional needs. It found that no mix of food items could satisfy vitamin D, B12, and calcium needs within a 650 km radius. While urban agriculture reduced the required radius by 10-15 km, significant nutrient fortification or supplementation was still necessary to localize the food system.

This study investigated the impact of COVID-19 on productive activities and the level of Integrated Pest Management (IPM) application among 108 urban agriculture farmers and extensionists in six areas of Mexico City. A digital survey in 2020 revealed that the sanitary emergency reduced extension services, though they continued with digital technologies. During the peak of COVID-19, 14% of farmers declined to sow the summer-fall season, and up to 75% reported 20% losses due to the epidemic. The main pest control strategies were mechanical (67%) and chemical (52%), indicating an intuitive understanding of IPM benefits despite farmers being unaware of its principles.

This article examines community gardens established for refugees from Vietnam, Cambodia, and Laos in the United States during the 1980s. It argues that refugee gardeners perceived a significant disconnect between their rural lives in Southeast Asia and the role of vegetable growing in the U.S., despite advocates emphasizing continuity with their past. The gardens provided a measure of economic empowerment, but highlighted the disjuncture in their resettlement experience.
