This study investigated institutional support for youth-owned Small, Medium, and Micro-Enterprises (SMMEs) in Durban's urban agribusiness sector using a quantitative methodology. Findings indicated that CSR interventions had not yielded a fundamental impact, and there was a lack of tangible, result-driven institutional support from policymakers and authorities. Furthermore, targeted technological transfer was a constraining factor, and a lack of monetary and non-monetary access hampered the SMMEs' competitiveness and profitability.

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.

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.

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 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.

Murtah Shannon, Kei Otsuki, Annelies Zoomers, Mayke Kaag · Urban Studies · Mozambique (Beira)

This article examines the implications of global interventionism in African cities for existing claims to urban space, particularly those of farmers, using Beira, Mozambique, as a case study. A historical-political analysis demonstrates that urban farming has been a distinct feature of Beira's urbanism amidst successive and contradictory state-land regimes. A new urban regime, formed by municipal leaders and international donors, aims to erase urban agriculture from the city through urban 'development', indicating a need for better understanding of manifold claims to urban space beyond slum urbanism.

Guillermo Olivera, Kenia Zavaleta · Repositorio Digital Institucional de la Universidad de Buenos Aires (Universidad de Buenos Aires) · Mexico

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.

This paper argues that community gardens should be a prioritized element of green infrastructure to improve cities' adaptation to climate change. Community gardens can reduce urban heat islands, provide ecosystem services, and increase stormwater retention. However, a qualitative analysis of 18 policy documents for Baltimore, Chicago, and New York City, U.S.A., found that green infrastructure for climate change adaptation prioritizes rain gardens, bioswales, and green roofs, but seldom acknowledges the role of community gardens.

Maurice Dasylva, Ngor Ndour, Bienvenu Sambou, Sara Danielle Dieng · European Scientific Journal ESJ · Senegal (Ziguinchor)

In Ziguinchor, Senegal, the peri-urban rice farming system contributes to food security but is ignored by decision-makers and suffers from urbanization and physicochemical changes in rice field soils. An agronomic diagnosis, based on 180 yield squares (1/4m side) installed in 4 peri-urban valleys, showed average yields of 4.79 ± 0.35 t.ha-1. However, urbanization, silting, acidification, and progressive salinization of soils are the main limiting factors for this production system.

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.

Rainer Einzenberger, Michaela Hochmuth · Digital Commons - Lingnan (Lingnan University) · China (Hong Kong)

An interview with Professor Kin-Chi Lau was conducted in March 2015 regarding the Urban Gardening Project at Lingnan University of Hong Kong. The interview portrayed the project's history, structures, and organizational characteristics, focusing on the challenges and difficulties participants faced in realizing the project.

Chiara Certomà, Lorenzo Chelleri, Bruno Notteboom · Urban Studies · Italy (Rome)

This paper investigates informal planning practices and "fluid governance" in urban public spaces, using the case of Parco delle Energie in Rome, Italy, and a comparative analysis of international cases. It found that politically progressive urban gardening challenges traditional governance networks and redefines public space functioning by transforming green spaces into food production and collaboratively managed areas through informal planning. This demonstrates that urban gardening worldwide challenges traditional planning perspectives and governance, turning citizens' dissensus into a productive force.

Alessandra Manganelli, Pieter Van den Broeck, Frank Moulaert · Territory Politics Governance · Global

This theoretical paper points out that Alternative Food Networks (AFNs) encounter governance challenges stemming from organizational growth pains, the search for cultivable land, and confrontation with urban planning policy and state structures that have a low affinity with urban agriculture. As AFNs develop, various governance tensions arise both within their organization and in their institutionalization processes. The paper redefines hybrid governance to elucidate these dynamics, suggesting that existing agro-food literature insufficiently addresses the complexity of AFNs' governance.

This article describes the obstacles to implementing public policy for family agriculture in urban areas of Brazil. Representations associated with rural-agricultural concepts have shaped the classification criteria of rural technical assistance technicians, limiting the policy's application in urban settings. Social movements in Rio de Janeiro highlighted the lack of access for urban family farmers to agrarian policies, leading to the recognition of urban family agriculture as a public problem.

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.

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.

This study analyzed food security in two medium-sized cities in Western Mexico using secondary data and field research. It found that while these highly globalized cities had a low degree of food security, extensive domestic backyard agricultural activities significantly raised family-level food security. A critical finding is that this potential for urban food security is not valued by governmental institutions.

Ashenafi Tilahun Hailie · IGI Global eBooks · Global

This chapter assessed the benefits of urban agriculture in a study area, using qualitative and quantitative analysis aligned with a sustainable livelihood framework. Findings indicated that urban agriculture is sustained by sex indiscrimination, migrant dominancy, poor educational status, and agricultural background. While assets like land access and fertile soil were promising, skills, knowledge transfer, labor ability, and good health were found insufficient. Identified vulnerabilities included population explosion, absence of good governance, frequent natural calamities, land tenure insecurity, and seasonality of prices.

Rikawanto Eko Muljawan · Prosiding Konferensi Nasional Pengabdian Kepada Masyarakat dan Corporate Social Responsibility (PKM-CSR) · Indonesia (Surabaya)

In East Java, Indonesia, rapid infrastructure development leads to approximately 100 hectares of agricultural land being converted annually, reducing food supply. In Surabaya, 2000 hectares are controlled by developers, with some loaned for farming, and the local government supports urban farming for 624 households on 400 hectares. The abstract suggests that developers, who benefit from extensive land conversion, should contribute to agricultural resource improvement through Corporate Social Responsibility funds for agro eco-technology programs.

Riska Rahma Arriani, Mardwi Rahdriawan · Teknik PWK (Perencanaan Wilayah Kota) · Indonesia (Jakarta)

A qualitative study using purposive sampling investigated the reasons for decreasing community participation in the government-initiated Urban Farming Program at Rusun Marunda, Jakarta, Indonesia. The program, which started with 50 farmers in 2014, saw participation drop to only 5 farmers by 2019. The study found that obstacles in farming demotivated farmers, leading to a decline in participation, particularly among those with economic-egoism motivations.

Chiara Certomà, Chiara Tornaghi · Ghent University Academic Bibliography (Ghent University) · Global

This book is a collection of chapters unpacking the forms, functioning, and meanings of urban gardening in the context of the neoliberal transformation of cities. It offers an overview of diverse claims in the micro-politics of garden activism and discusses how these projects are fraught with social solidarities and divisions, empowerment and learning processes, conflicts and negotiations. The collection aims to contribute to a critical discussion of the “politics of urban space” and enrich the emerging debate on radical, critical, and political gardening.

Global urbanization and food production are in direct competition for land. Displacing crop production from urban and peri-urban land due to soil quality issues will demand a substantially larger proportion of the Earth’s terrestrial land surface than the area lost to urban encroachment. This risks triggering distancing effects, unfair social-ecological teleconnections, and amplifying effects within the Earth System, potentially leading to food riots in cities of the Global South. The paper identifies multi-level leverage points, specifically an advisory global policy aligned with regional policies enabling robust common property rights for bottom-up actors in urban and peri-urban agriculture (UPA), to navigate urban expansion away from fertile croplands.
