To identify the main constraints to the expansion of urban agriculture (UA) in Benin, a systematic literature review, a survey among experienced urban gardeners, and in-depth interviews with stakeholders were conducted. The synthesis revealed five predominant constraints: lack of land and tenure insecurity, insufficient government support, restricted market access, limited access to productive factors, and inequality issues. Specifically, the survey indicated a political unwillingness, which was explained by the unperceived benefits of investing in UA and the lack of enforcement of urban development plans.

This research examines urban farming, specifically vertical farming methods, in Singapore. Despite substantial public and private investment in R&D for high-tech, high-yielding vertical farms, Singapore faces a highly constrained urban environment where land scarcity is exacerbated by a complex regulatory land use framework.

Paola Clerino, Agnès Fargue‐Lelièvre · Sustainability · France

This study used a participatory approach with French urban agriculture stakeholders to identify sustainability objectives and 21 criteria for professional intra-urban farms. Six objectives were established, and agro-environmental and socio-territorial criteria were deemed more important than economic ones, with food production not being mentioned. A critical finding was that decision-makers focused more on projects' external sustainability and urban farmers' agricultural background, suggesting a reliance on farmers for internal sustainability rather than direct assessment.

In the Bonearense region, urban expansion is encroaching on fertile plains, impacting territorial characteristics. While urban and peri-urban agriculture contributes to food sustenance for the AMBA population, it has not been sufficiently recognized for green area recovery, organic waste recycling, and wastewater management. Regional authorities have begun to acknowledge urban agriculture's role in combating urban poverty, but local economic development faces challenges in mediating food security and recreational services amidst pressures from urban real estate and agro-industrial production.

John Taylor · Frontiers in Sustainable Food Systems · United States (Rhode Island)

This long-term replicated trial in Rhode Island evaluated the yield performance and soil quality impacts of four small-scale food production systems over three summer growing seasons. While total marketable food yields (2.22 to 2.96 kg m-2) were modest compared to biointensive agriculture (4.64 kg m-2), individual crop yields often exceeded regional and national averages without soil quality loss. The study addresses a lack of experimental research on urban agriculture and provides a framework for normative research, offering more reliable yield estimates for modeling urban production potential.

Rebecca Leigh Rutt · Journal of Political Ecology · Denmark (Copenhagen)

Ethnographic research on a small rooftop garden in Copenhagen, Denmark, explored how urban farming initiatives interact with neoliberal trends. The study found that communal, eco-social urban farming endeavors are entangled in the city's neoliberal turn, with formalization processes and austerity measures both nurturing and endangering these initiatives. Neoliberal labor, food systems, and housing policies are shown to subvert convivial urban farming efforts.

Mosen Farhangi, Margherita Turvani, Arnold van der Valk, G.J. Carsjens · Sustainability · Netherlands (Amsterdam)

An ethnographic study in Amsterdam, Netherlands, analyzed barriers to the integration of high-tech urban agriculture (HTUA) into urban planning processes. The research revealed a lacking connection between planning actors and HTUA technology developers.

Ulrich Häpke · sub\urban zeitschrift für kritische stadtforschung · Germany (Ruhrgebiet)

While statistical data demonstrates the significance of urban agriculture in German cities and metropolitan areas, urban agriculture faces the problem of constant land loss despite its proximity to consumers. The example of the Ruhrgebiet highlights challenges such as land loss and high proportions of leased land, indicating governance issues faced by urban agriculture.

Sileshi Azagew, Hailu Worku · ENVIRONMENTAL SYSTEMS RESEARCH · Ethiopia (Addis-Ababa)

This study assessed the status, accessibility, and constraints of urban green infrastructure (UGI) in Addis Ababa, Ethiopia. It revealed that UGI land use decreased by 9.2% from 2003 to 2016, with urban agriculture declining by 11.9%. City residents lack sufficient recreational UGI, with park per capita at a very small 0.37 m² compared to Ethiopian standards of 15 m², and over 90% of the population lacking access to existing parks within walking distance. Major constraints identified include weak implementation of development plans, density, built-up area expansion, and lack of priority for UGI development.

Carrie Ann Benjamin · Sociální studia / Social Studies · France (Paris)

This study examines community gardening and participatory urbanism in Paris, focusing on the Goutte Verte, a temporary nomadic community garden. The continued existence of the Goutte Verte is in opposition to the city's much-needed housing, with gardeners caught between a desire for green space and a demand for comfortable housing. Community gardens are shown to act as a material alternative to urban planning and governance that often fail to account for a "place to breathe" in the city.

Amélie Robert, Jean Louis Yengué, A. Fanny, Mikael Motelica‐Heino, Edmond Hien, Alain Sanou · Risco Revista de Pesquisa em Arquitetura e Urbanismo (Online) · Africa

This research, conducted in Ouagadougou, Burkina Faso, utilized in situ observations, interviews with farmers and decision-makers, and an analysis of planning documents. It found that urban agriculture has experienced a significant increase in surface area and is popular among city residents. However, it is not officially considered in urban planning, revealing divergences in viewpoints between farmers and public decision-makers.

This article analyzes the role of water user organizations in the construction of water scarcity within the Chilean ideological and legal water context. The existence of urban gardens in the north of the country is notable in this context, which is oriented towards water use efficiency.

Sarah Taylor Lovell · Urban Agriculture & Regional Food Systems · Global

Despite increasing awareness and proposals for urban agriculture implementation, broad integration into the urban environment has not yet been observed. In most cities, the level of food production has not expanded significantly enough to impact the supply of vegetables, fruits, or other products. Key barriers limiting widespread adoption of urban agriculture include land access, zoning and tax policies, risks of soil and air contaminants, and urban forestry plans neglecting food security.

Nisa Maidah Rahmawati, Joko Winarno, Agung Wibowo · · Indonesia (Jakarta)

This study investigated community empowerment activities through urban farming in Marunda flats, North Jakarta. The flats' irrigation has deficiencies and group working is not yet fair, leading the society to choose to do agriculture activities by themselves. The research identified external factors (natural resources, environments, group dynamics, networking, human resources, policy, facilities and infrastructure) and internal factors (skill, non-formal education, and income) that obstruct empowerment activities.

Pierre Jassogne · · Belgium

SAULE (Urban Agriculture Housing Ecosystem Symbiosis) was a co-creation project conducted in Brussels, Belgium, from 2017 to 2020, involving citizens, urban agriculture professionals, researchers, social information specialists, and urban planners. Focused on the Ferme du Chant des Cailles urban agriculture site and the Archiducs – Logis-Floreal neighborhood, the project was initiated due to construction threats to the site. The research aimed to reflect on the challenge of combining ecological transition and social cohesion at the Brussels regional level.

Dona Pickard · Sociological Problems Journal · Bulgaria (Sofia)

This article analyzes the attitudes toward urban agriculture as an instrument for sustainable urban policies among local authorities, practitioners, and civil groups in Sofia, Bulgaria. Based on data from the research project "Urban agriculture as a strategy for improving the quality of life of urban communities" (2016–2020), the analysis reveals existing deficits in communication and information exchange between these actors. Factors for these deficits and ways to overcome them are also outlined.

This study was conducted in Malaysia to identify deterrent factors hindering "community buy-in" in urban farming projects and to understand how to overcome these problems. The research aims to identify these factors to achieve and sustain community buy-in in urban farming projects in the future.

Ana Carla Alves Gomes, Maria Lúcia Brito da Cruz · Revista Campo-Território · Brazil

This study investigated the spatial distribution of Urban Agriculture (UA) in Fortaleza, Brazil, particularly in the Lagoa Redonda neighborhood, and the permanence of these gardens amidst territorial disputes over urban space. Using bibliographic and secondary data surveys, site visits, and geoprocessing techniques, it analyzed the feasibility of UA reproduction and the implementation of specific policies for the activity. The study points to governance challenges, specifically territorial disputes concerning the permanence of urban agriculture in urban spaces.

Stefan Staehle · sub\urban zeitschrift für kritische stadtforschung · Global

This study offers an alternative perspective on the critical practice of urban gardening, highlighting the ambivalence of the phenomenon. Specifically, the decoupling of social and artistic critique is shown to lead to a programmatic weakening of initiatives and their co-optation by neoliberal urban policies. This can reverse the critical practice of spatial appropriation into its opposite.

Jongwoo Kim · · South Korea

This study aimed to propose activation measures for school-based urban agricultural education in South Korea, using focus group interviews with teachers and literature analysis. Teachers reported a lack of school gardens, particularly open-field plots, and difficulties in management, highlighting the need for personnel. They also noted the use of container gardens to compensate for the lack of space and the selection of crops for student harvesting experiences.

Bruce G. Ferguson, Helda Morales · · Mexico (Chiapas)

The Laboratorios para la Vida action research team in Chiapas, Mexico, trains educators to use school gardens and local food systems as venues for experiential learning. However, teachers face a host of hurdles to successful garden programs, including high teacher turnover, lack of space, and the difficulty of matching garden growth with the national curriculum calendar.

Andrea Baier, Christa Müller · · Germany

This chapter discusses the results of semi-structured face-to-face interviews conducted in 2016 with activists in three urban community gardens in Bremen, Cologne, and Kassel, Germany. The study focused on the relationship between urban projects and municipal administrations. It showed that initiatives taken by grassroots activists to form collaborations with administrative actors are limited, though the traditional role of citizens can be extended in new local partnerships.

Jeroen Schütt, Bas Amelung · · Europe

This research, conducted by the Science Shop of Wageningen University and Research, estimated the monetary value of ecosystem services in the Lutkemeerpolder, Amsterdam, which is slated for conversion into a business park. The study identified food production, air purification, recreation, and the effect of greenery on housing prices as key services, valuing them at 1.5 to 8.6 million euros per year. These ecosystem service values were not considered in the original decision-making twenty years ago, leading to a recommendation to reconsider the development plan.

Luca Sára Bródy, Mandy de Wilde · Local Environment · Netherlands (Amsterdam)

Based on a qualitative study of 19 community gardening projects in Amsterdam, this research argues that community gardens function as “controlled space.” Various institutional governance actors, including local government, welfare organizations, green NGOs, and housing associations, exert varied levels of influence and control over the gardens. These relations both impair and enable the civic participation of gardeners, the inclusive potential of gardens, and an alternative, local food provision and distribution.

Anna Shortly, Thembela Kepe · Forests Trees and Livelihoods · Canada (Toronto)

This paper explores the opportunities and challenges of incorporating foraging practices into parks planning and management in Toronto, Canada, where foraging is often not permitted in urban parks. The study, based on a scan of practices and interviews, concludes that urban parkland managers should establish dedicated spaces like community orchards to safely and sustainably accommodate foraging, acknowledging current restrictions.
