Barriers to urban agriculture in Africa: a bibliometric and content co-occurrence analysis of the literature
2026hawamkwela@yahoo.com MKWELA, Emiliana Assenga · Cogent Food & Agriculture · Africa
A bibliometric analysis of 504 journal publications from January 2020 to December 2024 and a content co-occurrence analysis were conducted to understand barriers to urban agriculture in Africa. Four research clusters emerged, including 'policy neglect or opposition in urban agriculture'. Content analysis revealed that vegetable production in urban agriculture is negatively affected by wastewater use, heavy metal contaminated soil, limited access to productive factors, and policy neglect or opposition.

2025Mohammed Adem Ali, B. Lilly Grace Eunice · Discover Sustainability · Ethiopia
Urban agriculture in Ethiopia is a vital livelihood strategy, contributing to employment, income, and food security. Despite its significant contributions to GDP and urban employment, its potential is insufficiently utilized due to structural obstacles. These hurdles include restricted access to land and water, deficient regulatory frameworks, poor institutional support, social stigma, and environmental risks, and it is insufficiently acknowledged in urban development strategies.

2025Tesfay, Hailay, Machethe, Charles · AgEcon Search (University of Minnesota, USA) · Ethiopia (Tigray)
This paper examines the effect of Ethiopia's land certification program on the land tenure security of rural and peri-urban farming households in the Tigray region. Analyzing cross-sectional data from 500 respondents using logistic regression, the study showed that the program's effect is significantly influenced by the geographic location of farm households. The program produced better results for rural farmers than for peri-urban farmers, with certified households in rural areas being less likely to experience a change in their land tenure (less secure land tenure) compared to certified farmers in peri-urban areas.

2024Emmanuel Olatunbosun Benjamin, Abiola Adegoke, Gertrud Buchenrieder · Land · Nigeria (Lagos)
This exploratory qualitative research, conducted in Lagos, Nigeria, used focus group discussions to compare the perspectives of private urban farmers and public sector representatives on innovative urban farming. Urban farmers identified a lack of public sector support for circular agri-food technologies, while public sector representatives attributed issues to farmers' behavioral and educational shortcomings, including poor coordination. These differing views highlight complex dynamics and a need for structural changes and stakeholder dialogues to develop effective urban farming policies in Sub-Saharan Africa.

2023Mallika Sardeshpande, Charlie M. Shackleton · People and Nature · South Africa
This study interviewed 80 urban foragers in four cities in South Africa's eastern coastal region to understand urban foraging in a developing nation context. Foragers began foraging in childhood, viewing it as a cultural and recreational activity, but formal green spaces were not used for foraging and were perceived as poorly provisioned in urban planning. This indicates a lack of governance in urban planning regarding foraging.

2020Mawuna Donald Houessou, Mirte van de Louw, B.G.J.S. Sonneveld · Sustainability · Benin
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.

2020Murtah 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.
