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.

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.

Amsalu Woldie Yalew · Regional Economic Development Research · Ethiopia

This paper provides an overview of urban agriculture in Ethiopia, synthesizing existing evidence on its role in the overall agricultural sector, urban economy, and urban employment, based on official reports and statistical surveys. Despite scant evidence, urban agriculture shows considerable contributions. However, the review reveals existing gaps in institutional and policy support for urban agriculture.

Mr. Isaiah ACQUAH, Dr.Sc. Joseph Ato FORSON, Dr.Sc. Theresa Yaaba BAAH-ENNUMH · DOAJ (DOAJ: Directory of Open Access Journals) · Ghana

This qualitative exploratory study in Accra Metropolitan Assembly, Ghana, investigated the effect of urban growth and concretization on urban farming households' livelihoods and food security. The study, using interviews and spatial imagery, found that urban farms face challenges due to inadequate land use planning and support, leading to a loss of farmlands. Significant challenges identified include limited farming space, limited resources, continuous increase in buildings, and inadequate education for urban farmers.

Zeinab Abd Elkader, Ahmed Haroun · Fayoum University Journal of Engineering · Egypt

The legislative and executive challenges of roof gardens in new cities in Egypt were clarified. Theoretical studies, including an applied study in Sheikh Zayed City, were presented. The research suggests that while roof gardens offer environmental, social, and economic benefits, challenges exist for their widespread application.

Ana Mélice Dias, Teresa Marat-Mendes · Portuguese National Funding Agency for Science, Research and Technology (RCAAP Project by FCT) · Portugal (Lisbon)

In Lisbon's Greater Area, Portugal, the morphological impact of municipal planning instruments (Municipal Master Plans) on urban agriculture was investigated. It was concluded that current planning regulations prioritize leisure and aesthetic solutions for urban agriculture uses, rather than design solutions that address economic growth or ecological diversity.

Fanni Bársony · Tér és Társadalom · Hungary

This study examines urban community gardens in Hungary through fieldwork and group interviews. It investigates how these gardens function as urban commons, focusing on community characteristics, resource relationships, and sharing practices. The research concludes that for urban commons, it is insufficient to focus solely on the shared resource and access conditions; the commons must be examined in relation to the operating community.

Mary Njoki Mwaura, Sabina Wangia, Japheth Ododa Origa, Lee Ernest Mbatia Oliver · Journal of Agricultural Extension · Kenya (Nairobi)

This study investigated the influence of urban extension workers' socio-economic characteristics on farmer empowerment in Nairobi County, Kenya, using data from 64 extension workers. While extension workers' characteristics positively influenced the choice of extension methods, explaining 37.2% of farmer empowerment, a significant finding was that 49.9% of extension workers were unaware of adult learning principles (ALPs). The study recommends training extension workers in ALPs and ICT techniques to improve extension methods.

Fatiha Hakimi, Mohamed Brech · Zenodo (CERN European Organization for Nuclear Research) · Morocco

This study assessed the practices, potentials, and constraints of peri-urban agriculture (PUA) in Rabat Metropolis, Morocco, using field observation, interviews, and surveys with 50 randomly selected farmers. While PUA contributes to economic development, employment, and food supply, the study found significant legal constraints, including the absence of regulating laws and the obligation for some farmers to pay housing taxes. Technical constraints such as insufficient workforce, high labor costs, difficult access to irrigation water, and lack of training also hinder PUA growth.

Maximilian Manderscheid, Valentin Fiala, Bernhard Freyer · Zenodo (CERN European Organization for Nuclear Research) · Global

This report D4.3 describes the status quo analysis and documentation of Edible City Solutions (ECS). Over 300 ECS were identified in Berlin and Montevideo, and online research was conducted in Carthage and Lomé, after which a total of 84 ECS were documented in detail using a mixed-method approach (online survey, interviews, workshops, etc.). Most documented ECS take the form of urban gardening and focus on social benefits like providing education and fostering social cohesion, but the report does not detail specific challenges or limitations regarding governance.

Leelanayagi Ramalingam, Juwaidah Sharifuddin, Zainal Abidin Mohamed, Fazlin Ali · International Social Science Journal · Malaysia (Klang Valley)

This study analyzed data from 375 volunteers in Community-based Urban Agriculture Programmes in Klang Valley, Malaysia, to determine the relationship between motivation and satisfaction. It found that volunteer satisfaction was primarily influenced by external factors like campaigns, support groups, extension departments, community, and government policy, followed by love of farming, social referents, and values. The program faces problems in attracting and retaining enough volunteers, indicating a governance challenge for sustainability.

Arantza Elena Sanchez Gutierrez · · Mexico

In Querétaro Municipality, Mexico, a strategy was designed and implemented to increase and incentivize the use of urban agriculture. Previous strategies implemented in Mexico had resulted in low participation and abandonment of practice due due to low interest from inhabitants and a lack of will to follow through on plans. This qualitative research analyzed the causes of these failures using User-Centered Design tools and Design Thinking. Findings showed that a "strategy of appropriation," emphasizing a sense of belonging, well-being, and commitment, resulted in an increase in this variable, which influences the abandonment of agricultural practices.

Daiara Batista Mendes · Geografia em Atos (Online) · Brazil (Pirapozinho)

This article identifies the potentialities of urban agriculture in Pirapozinho, São Paulo, focusing on food and economic use. Based on field research and interviews, the study found that urban agriculture provides quick access to quality products and fosters close farmer-consumer links. However, it also found that urban agricultural practices have not received due governmental attention at national or local scales, despite their potential.

Nadine Appelhans, Sabine Baumgart · · Morocco

An analysis of documents related to planning and agriculture and interviews with experts in Morocco indicated that urban and rural issues were treated as separate areas. Urban development affects daily travel distances as urban expansion changes distances between cultivated land and dwelling places. Data from Morocco show a lack of serious support for urban agriculture and animal husbandry in expanding urban agglomerations.

Meng YE, Tomohiko Yoshida · Urban and Regional Planning Review · China (Beijing)

This study examined user evaluations of allotment gardens in Beijing, China, where demand is rising. The overall evaluation was between good and general, with high marks for landscape and facilities but low marks for service, guidance, agricultural festival activities, rent, sanitary facilities, and skilled labor. The consortium operation mode received the best evaluation, while the individual mode had the lowest.

Kathrin Specht, Felix Zoll, Henrike Schümann, Julia Bela, Julia Kachel, Marcel Robischon · Sustainability · Global

Nineteen qualitative expert interviews were conducted to identify perceptions of sustainability, social acceptability, and ethical aspects of new urban food production approaches. While major perceived benefits included educational effects and efficient resource use, significant conflicts involved negative side-effects, legal constraints, and high investment costs. Acceptance barriers were largely tied to the "unknown," encompassing a lack of understanding of new approaches, uncertainty about benefits, health risk concerns, unfamiliarity with products, and ethical doubts about animal welfare. The study concluded that adapting the unsuitable regulatory framework, which discourages investors, is a crucial first step to foster dissemination of urban food production approaches.

Rebecca St. Clair, Michael Hardman, Richard Armitage, Graeme Sherriff · Urban Studies · United Kingdom (Manchester)

This study, conducted in Wythenshawe, Manchester, UK, highlights the difficulties of collaboration among organizations in a lottery-funded urban agriculture project. Due to local authority cutbacks and a lack of funding, community groups and charitable organizations compete for space and resources, leading to a "siege mentality" where organizational self-preservation takes precedence over cooperation. This paradoxically results in groups with similar goals working against each other instead of collaborating.

Alexandra Rodríguez Dueñas · DOAJ (DOAJ: Directory of Open Access Journals) · Ecuador (Quito)

Quito’s Participatory Urban Agriculture Project (AGRUPAR), launched in 2002, supports vulnerable populations by providing technical assistance, capacity building, and microcredit for urban farming, aiming for food security and employment. While integrated into local government and recognized with the Future Policy Silver Award 2018, the program faces significant challenges including administrative changes, budget cuts, and restrictive land-use legislation.

Mathilde Martin-Moreau, David Ménascé · OpenEdition (OpenEdition) · Global

The deployment of urban agriculture relies on initiatives from companies, startups, and non-profit organizations, alongside support from public authorities, especially local governments. Challenges include the need to raise consumer awareness of new production methods and to train urban farmers for quality supply chains. The abstract indicates that commitment from local stakeholders is crucial for scaling up urban agriculture projects.

Nicolette Tamara Jonkman, Boris Jansen · Current Opinion in Environmental Sustainability · Sub-Saharan Africa

This literature review on urban agriculture (UA) in Sub-Saharan Africa (SSA) identifies a significant constraint: conflicting stakeholder perceptions of UA, which hinders its development into a sustainable business. Some view UA as illegal and unsustainable, while others see it as a means to food security and employment. The review highlights a knowledge gap regarding land-use history and its effect on UA soil composition and nutrient status, proposing that UA sustainability requires understanding this historical context to build inclusive business models.

I Gusti Agung Adi Wiraguna, Ngakan Putu Sueca, I Made Adhika · RUANG-SPACE Jurnal Lingkungan Binaan (Space Journal of the Built Environment) · Indonesia (Denpasar)

This mixed-method study in Denpasar, Indonesia, investigated factors driving the conversion of urban agricultural land, primarily rice paddy fields. Despite a local government requirement for 30% urban open space, statistical data showed an average annual decrease of 31.86 hectares of farming land, from 2,632 hectares in 2010 to 2,409 hectares in 2017. The study revealed that various parties, including the government, community, private sector, and social institutions, play important roles in directing this land conversion.

María Carolina Feito, Sofía Boza, Santiago Peredo · Repositorio Digital Institucional de la Universidad de Buenos Aires (Universidad de Buenos Aires) · Argentina

This study focused on the reality of Urban and Peri-urban Agriculture (AUPU) in Latin America, comparing cases in the Buenos Aires Metropolitan Area and the Santiago Metropolitan Region. Both cities form complex territories strongly related to their periphery, but the debate regarding AUPU's future development model remains open, reflected in contradictions even in public policies. The strong link between family farming and AUPU further complicates the situation due to the intrinsic limitations of family farming.

Mawuna Donald Houessou, B.G.J.S. Sonneveld, Augustin K. N. Aoudji, Fréjus THOTO, Smith A. R. Dossou, D. J. Snelder, Anselme Adégbidi, Tjard de Cock Buning · Sustainability · Benin

A study explored and compared international standards of prevailing organizations and their functioning among 261 urban gardeners in two cities in Benin. It found that a vast majority of urban gardeners are members of a cooperation. However, their membership is largely titular because gardeners mostly behave semi-autonomously, and few decisions are taken collectively. The obvious economic advantages of leveraging bargaining power, reducing transaction costs, and increasing possibilities for loans are seriously underutilized.
