Sean Olivia Nicholas, Niki Harré · Agroecology and Sustainable Food Systems · Singapore

A review of existing literature and a case study of three urban farms in Singapore were conducted to examine their community contributions. Content analysis of 27 interviews with employees and volunteers revealed that these farms empower participants, generate social capital, provide jobs, involve marginalized groups, and promote pro-environmental behaviors. However, the farms were limited by poor job prospects and lower-than-expected yield.

Stefania Lovo, Samantha Rawlings · The World Bank Economic Review · Ghana, Nigeria

This study investigated the impact of e-waste dumping sites on neonatal and infant mortality, focusing on two major dumpsites in Ghana and Nigeria. Using a difference-in-differences approach, outcomes were compared for children born near and far from dumpsites before and after their creation. E-waste sites increased neonatal and and infant mortality for those living closer to the sites, with event studies suggesting effects emerge two to three years after site openings. There is suggestive evidence that contamination of water and of urban farming produce are among the drivers of the observed effects.

This study assessed the potential of peri-urban areas for sustainable development, focusing on a pandan farming community in Pathum Thani, Thailand, using the Community-Based Resilience Analysis (CoBRA) approach. The community identified COVID-19, water quality, and solid waste as their primary disruptive challenges. The study concluded that the community was moderately resilient to hazards, and COVID-19 was the primary disrupting event over the past 10 years.

Kalpana Waiba, Alina Maharjan, R Shakya · Journal of Environment Sciences · Nepal

This study investigated the status and impact of urban agriculture on the population in the Kathmandu Valley, Nepal. A structured questionnaire survey of 230 families showed that 51% of respondents had access to growing areas and 76% chose kitchen gardening. The main motivations were economic considerations (50%) and personal satisfaction (20%). Participants reported cultivating 55% of their diet, contributing to good health, though challenges such as plant diseases (40%) were present.

Kelvin Haule, Bupe Kabigi · Ghana Journal of Geography · Tanzania

This study analyzed land markets and their influence on peri-urban agriculture and livelihood strategies in Tanzania. It found that widespread monetary land markets, including formal, informal, speculative, entrepreneurial, and land grabbing forms, are transforming peri-urban agriculture into non-farm activities. These informal changes are causing a “sendoff” of peri-urban agriculture, and if unmanaged, land markets are suggested to become a blight for indigenous people selling land.

Patsy Kraeger, Rhonda Phillips, J. H. Lubin, Jonathan Weir, Kristina R. Patterson · Sustainability · United States

This study investigated the connection between local farmers markets (FMs), community-supported agriculture (CSAs), and physical well-being at the state level across the 50 states of the United States. Analyzing 2016 data from the United States Department of Agriculture using an ordinal logistic regression model, the study found an inconclusive relationship at the state level. While local FMs and CSAs may increase physical well-being, this study did not find such an increase.

Mohammed Elyaagoubi · African J of Economic and Sustainable Development · Morocco

This study investigates the decline of agricultural land in Guersif City, Morocco, due to rapid urbanization. Sociological surveys and technical data from 1954 and 2021 were used to identify and quantify the rate of agricultural land loss. The preservation of urban agriculture in Guersif faces a real challenge from other, more profitable activities.

Domenic Vitiello · Urban agriculture · United States

US cities have developed urban agriculture support systems reflecting competing values, with some prioritizing public good and others economic gains. A chapter reflecting on urban agriculture planning in Chicago and Philadelphia notes that institutional structures significantly impact equity and justice. The study indicates that the existing urban agriculture support systems in these cities may not adequately promote equity and justice.

Farhang FaghihLarijani, Elaheh Amani Vamarzani · DOAJ (DOAJ: Directory of Open Access Journals) · Iran

This study investigated whether an independent legal system exists in urban areas of Iran to recognize, maintain, and develop urban agriculture. It found that despite urban laws recognizing agricultural activities, legislators have not enacted a comprehensive law specifically for urban agriculture, nor explicitly included it in urban land definitions. The study hypothesized that a primary challenge is the lack of a compatible legal framework.

Efadul Huq · International Journal of Urban and Regional Research · Bangladesh (Dhaka)

This article argues that in the global South, ecological infrastructure often displaces marginalized urban dwellers by erasing existing informal agricultural practices, or "green informalities." Based on research with urban farmers facing eviction in Dhaka, Bangladesh, it highlights that these green informalities are crucial for understanding grassroots practices and collective power-building. The study advocates for recognizing the political and affective dimensions of informal urban agriculture as a socially just ecological infrastructure that prioritizes justice and dweller agency.

A study of 18 urban community gardens in Central Coast, California, USA, used gardener surveys and field measurements to evaluate food production and its distribution. Gardeners produced an average of four pounds of food per week, saving an estimated $16 USD weekly. However, gardeners with greater food insecurity (larger families or lower incomes) were not the largest producers, indicating uneven benefit distribution despite high overall productivity.

Anna M. Roodhof · Journal of Agriculture Food Systems and Community Development · Netherlands

To map and analyze food forestry (FF) in the Netherlands, a survey of 109 participants and interviews with five experts were conducted, identifying 231 food forests established since 2017. The survey data indicates that while FF initiatives are diverse in goals, few focus on profitability. Practitioners are largely homogeneous, consisting of university-educated individuals aged 40 to 60.

Paula Mota Santos · Social Inclusion · Portugal (Porto)

Grassroots urban horticultural plots (hortas) in the Porto Metropolitan Area, Northern Portugal, are informal communities that have existed for decades, often involving over 20-30 people. However, these low-income urbanite horticultural communities are not cherished by city governance, which does not prevent their destruction. This incompatibility between urban governance and grassroots communities hinders the right to the city for the low-income urbanites who created them.

Yihang Hu, Junbiao Zhang, Yangmei Zeng, Jie Li · Land Degradation and Development · China

A study in Zhejiang Province, China, examined the impact of climate factors on agricultural production efficiency using a pooled OLS model. While precipitation production potential showed a significantly positive impact, the effects of temperature, evapotranspiration, and insolation were not significant or exhibited poor stability. Furthermore, the benefits of precipitation potential varied, with only a few cities experiencing significant improvements.

Belinda Li, Tammara Soma, Raghava Payment, Srishti Kumar, Nicole Anderson, Flora Xu, Phonpoom Piensatienkul · Canadian Food Studies / La Revue canadienne des études sur l alimentation · Canada

This study reviewed and categorized 73 food asset maps in Canada based on their included food assets and design characteristics. Most maps included built environment assets like grocery stores and food banks, as well as agriculture-based natural food assets such as farms, community gardens, and orchards. However, representations of Indigenous-focused food assets and non-agriculture-based natural food assets like forests, water bodies, and foraging areas were generally lacking. This lack of Indigenous perspectives reinforces the values of a settler-colonial food system within food asset maps.

Market gardening in Kinshasa's urban and peri-urban areas faces multiple constraints, including land insecurity, low natural soil fertility, the incidence of diseases and pests, weak technical support, climate hazards, poor input supply, and problematic marketing systems. These constraints limit yields in production sites and hinder the development of market gardening activities.

Lee D. Bryant, Roy Maconachie, Bastian Schnabel, Abubakarr Swaray, Howard Gigi, Solomon Gbanie, Kabba Haroun Bangura, Anthony Kamara, Prince Antwi-Agyei · Water Science & Technology Water Supply · Sierra Leone (Freetown)

This paper examined the environmental health status of three urban and peri-urban agriculture (UPA) sites in Freetown, Sierra Leone. Qualitative and quantitative data revealed heavy metal concentrations significantly exceeding regulatory limits in sweet potato leaves and arable soil. Additionally, soaring levels of faecal coliform bacteria were found in irrigation water, and crops were identified as hyperaccumulators for environmental contaminants.

Tri Wahyu Nugroho, Aulia Luqman Aziz, Hery Toiba, Ahmad Imron Rozuli, Suyadi Suyadi · JAPI (Jurnal Akses Pengabdian Indonesia) · Indonesia (Malang)

This community service activity in Mulyoagung Village, Malang, Indonesia, aimed to empower the local economy through urban farming by utilizing organic waste such as cocopeat and polybags as growing media. The program successfully enabled the community to adopt urban farming concepts, proving its effectiveness in addressing shrinking agricultural land and strengthening the local economy. However, it is also noted that sources of materials, human resources, and market access are among the obstacles causing urban farming failures.

This qualitative case study investigated the internal supply chain risk management for mustard greens (sawi) at the "Buruan SAE Mang Oded" urban farming group in Bandung City, Indonesia. Using the House of Risk method, the study identified 23 risk events and 23 risk agents within the supply chain, with 14 priority risk agents requiring control. The findings indicate significant challenges in managing the internal supply chain, suggesting that the current system faces numerous risks that hinder efficiency and effectiveness.

Matthew L. Richardson, John Taylor, Megan J. Thompson, Anusuya Rangarajan, Mamatha Hanumappa, Neith G. Little · PLoS ONE · United States (Northeastern United States)

This online survey of 394 urban growers, primarily in the Northeastern United States, profiled growers and assessed urban agriculture's state, identifying needs and challenges. Most growers were white (non-Hispanic), under 45, well-educated but without agriculture degrees. Urban agriculture was dominated by small non-profits and home/community gardens. A critical finding is that urban growers face diverse barriers, with the most common being land availability and long-term access in urban areas, and many reported low revenue or operating at a net loss.

Juan Camilo Fontalvo Buelvas, Maria Teresa Pulido Silva, Miguel Ángel Escalona Aguilar · Magazine Portal Bibliotech Digital (Universidad Nacional de Colombia) · Global

This bibliographic review identified the main problems of urban agriculture and actions for sustainability. The study found that the primary deficiencies in urban agriculture are inadequate management practices, a lack of organization, and absent or inefficient public policies. Key leverage points for change include agroecology, policies for land access and sustainable financing, and dissemination processes.

Lena Katharina Mietz, Bárbara Civit, Alejandro Pablo Arena · Agroecology and Sustainable Food Systems · Global

This review focuses on the present state and methodology of life cycle assessment (LCA) to evaluate the sustainability of urban agriculture. It notes that while urban agriculture is seen as a potential alternative for a resilient food system, existing case studies are mostly incomplete and lack diversity. Further research is needed, especially the integration of social and economic perspectives, to achieve a comprehensive scientific understanding.

Linh Dinh Hong, Khiem Phuong Huu, Diep Vu Bach, Tien Vu Quyet · Transactions of the Chinese Society of Agricultural Machinery · Vietnam

Using a national Vietnamese household living-standards survey dataset, this study applies a difference-in-differences (DID) approach combined with propensity score matching (PSM-DID) to assess the short-term impact of the COVID-19 pandemic on urban agricultural households in Vietnam. It finds that while the pandemic did not significantly affect household income, it reduced household expenditure -- both total household consumption and per-capita consumption -- and increased the number of household members participating in agricultural work as a short-term response.

Meiling Wu · Sustainability · China

A study of a Sharing Community Supported Agriculture (CSA) farm in China examined, through semi-structured interviews and thematic analysis, how external investment drives the conventionalization of alternative agriculture. The farm's low economic sustainability was the trigger that drew in external investment; investors then compelled the farm manager to relax adherence to organic agriculture's ecological values and principles and shift toward specialized, intensive farming to secure profitability, and a new business model was adopted that further entrenched this conventionalization.
