Barriers to urban agriculture in Sub-Saharan Africa
2020Julia Davies, Corrie Hannah, Zack Guido, Andrew Zimmer, Laura E. McCann, Jane Battersby, Tom Evans · Food Policy · Sub-Saharan Africa
This study investigated the association between urban agriculture (UA) and household food security in smaller African cities and towns, using survey data from 2,687 low- and low-middle income households in 18 urban areas with populations of less than 200,000 across Zambia and Kenya. The analysis found that 33% of households in the sample engaged in UA, but there was limited statistical significance in the relationship between UA and household food security. Key barriers identified were settlement formality, property rights, and distance from food retailers.

2020Nicole Paganini, Stefanie Lemke · Local Environment · South Africa (Cape Town)
This study, conducted from 2017 to 2019 in Cape Town, South Africa, and Maputo, Mozambique, explored urban agriculture's contributions to livelihoods and food availability through a food justice lens. In Cape Town, NGO-led urban agriculture regulated production and market access, serving wealthy consumers, with only 15% of farmers consuming their produce. In Maputo, urban agriculture contributed to local food availability, with 99% of farmers eating their produce, but farmers depended on intermediary-determined prices and faced unequal access to inputs. The study revealed stark structural inequalities and uneven power dynamics in both contexts.

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.

2020Idris Mohammed, Abdella Kosa, Nuredin Juhar · Agricultural and Food Economics · Ethiopia
This study assessed the economic linkage between urban development and the livelihood of peri-urban farming communities in Ethiopia, focusing on current practices and policies. Data was collected from 30 municipal officials and 200 evicted peri-urban farmers across five municipalities in the Amara regional state. Findings indicate that the continuous eviction of peri-urban farmers from their indigenous land for redevelopment negatively affects their livelihood, highlighting significant equity issues. Factors contributing to urban expansion include economic policy reform, private investor incentives, and public sector projects, further exacerbated by policy limitations and lack of municipal intervention.

2020Brittany Kesselman, Mvuselelo Ngcoya, Daniela Casale · Agroecology and Sustainable Food Systems · South Africa
This paper, based on research from two urban gardens in Johannesburg, South Africa, argues that contemporary urban dietary norms pose a challenge to urban agroecology. The dietary norms and practices of Johannesburg residents are poorly aligned with the production requirements and outputs of urban agroecology. Lessons from other countries suggest that the benefits of agroecology could be enhanced by targeting changes in food preparation and consumption practices.

2020Sileshi 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.

2020Derek Du Bruyn, Marietjie Oelofse · New Contree · South Africa (Bloemfontein)
This article investigates the Bloemfontein Municipality's efforts to establish Batho, a new location for black and coloured people (ca. 1918-1939), as a 'garden location' within the historical context of British-style urban planning and racist, segregationist policies. Initiatives included securing water supply, allocating allotment gardens, providing a fresh-produce market, and planting trees. While some motivations were aesthetic, others were deeply rooted in segregationist ideology. The article critically assesses whether these attempts to create a garden location were 'successful'.

2020Reuben Nwoye Okechi, Edna Ifeoma Chukwura, Christian Okechukwu Nweke · Journal of Advances in Microbiology · Nigeria (Owerri)
This study, conducted in Owerri, Nigeria from June to December 2019, evaluated the interactive toxic effects of ternary mixtures of sodium dodecyl sulfate (SDS) and divalent metals on Serratia marcescens (SerEW01) from the Otamiri River, a source for urban farming. The study found that both concentration addition (CA) and independent action (IA) models predicted lower toxicities compared to experimentally observed data. The Toxic Index and Model Deviation Ratio indicated a synergistic interaction of SDS and metal ions, resulting in higher combined toxicities than predicted, posing environmental hazards due to co-contamination.

2020Hillary A. Craddock, Elisabeth Fost Maring, Stephanie Grutzmacher · African Journal of Food Agriculture Nutrition and Development · Ethiopia
A mixed-methods pilot survey of 21 teachers and parents in Debre Berhan, Ethiopia, investigated household agricultural practices to understand foodborne illness risks. The study found that half of respondents using manure applied uncomposted manure as fertilizer, and many kept multiple animal species. This suggests a high risk of pathogen exposure for children and adults through contact with uncomposted manure and animals.

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.

2020F. Waswa, M. Mwamburi, I. I. C. Wakindiki, Roseline Chemutai · Journal of applied science and environmental management · Kenya
This study focused on soil physicochemical properties and fertility management in Ruiru Sub County, a peri-urban area in Kiambu County, Kenya. Soil samples from ten small contact farms (~0.1 ha) were analyzed, revealing that most farmers were tenants growing leafy vegetables, maintaining soil fertility with organic manures, and performing tillage by hand. These practices signal limitations imposed by small farm size and lack of land ownership, with soil fertility primarily limited by the interaction of soil pH, K, and Ca.

2020Oso Adeola Abiola · Zenodo (CERN European Organization for Nuclear Research) · South Africa
This review discusses vegetable production in South Africa, focusing on the impacts of root-knot nematodes (Meloidogyne species) on small-scale farming communities. The review highlights that these nematodes are a primary pest, causing delayed crop maturity, reduced yields, poor quality produce, and escalating production costs. This leads to substantial income losses for farmers and the abandonment of community gardens, intensifying challenges for vegetable production and food security.

2019Cosmos C. Alamanjo, Abimbola O. Adepoju, H. Martin, R.N. Baines · Zenodo (CERN European Organization for Nuclear Research) · Nigeria (Jos)
This mixed-methods study investigated farmers' perceptions, willingness, and capacity to use household sewage sludge as organic resources for peri-urban agriculture around Jos, Nigeria. Farmers were found to use a complex mix of fertilizers and were keen to utilize household sewage sludge for soil fertility, though constrained by accessibility. A critical finding was that household sewage sludge observed in the field is heterogeneous due to its proximity to urban refuse disposal, raising concerns for possible cross-contamination of pollutants and indicating a lack of extension guidance.

2019Nicolette 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.

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.
