This study analyzed urban and peri-urban agriculture (UPA) systems in major Sub-Saharan African cities, measuring carbon, nitrogen, phosphorus, and potassium fluxes and conducting biodiversity studies. In Niamey, low-input gardens showed annual gaseous carbon emissions of 20-25 t ha-1, predominantly CO2, and high-input gardens irrigated with wastewater had annual CO2-C emissions of 27 t ha-1, with N2O as a major nitrogen loss contributor. Animal manure stored in the open was subject to large carbon and nitrogen losses, indicating environmental tradeoffs. However, UPA gardens in Niamey maintained a large variety of fruit and vegetable species, with richness increasing with garden and household size and commercialization.

This study examines urban food security in South Africa, focusing on Cape Town, Msunduzi, and Johannesburg, and includes a critique of the City of Cape Town's urban agriculture policy. The abstract indicates that the policy was found to have significant shortcomings, particularly concerning local production and access to food. The research highlights various policy issues related to food access, dietary diversity, local production, and local markets within these urban contexts.

Dzodzi Tsikata · · Sub-Saharan Africa

This chapter examines urban women's livelihoods in sub-Saharan Africa since the 1990s, focusing on economic liberalization and the expansion of the informal economy. Urban agriculture, including home gardens, is identified as an increasingly important activity within this informal sector. Many women in the urban informal economy are employed by others or have been in the past, while industrial subcontracting, a source of informal employment, has been significant only in a few industrialized Sub-Saharan African countries.

This study introduces human urine as an alternative fertilizer source for urban agriculture, presenting case studies from Nigeria and Ghana. It suggests that proper collection and use of human urine can improve urban environmental sanitation and reduce crop production costs. The approach integrates agriculture, environment, and sanitation sectors.

Abegunde A. A, Emmanuel Olufemi Omisore, O. F. Oluodo, D O Olaleye · African Journal of Agricultural Research · Nigeria (Lagos)

A study in the Eti-Osa local government area of Lagos, Nigeria, investigated the socio-spatial effects of urban horticultural gardens. Of 75 identified gardens, 63 managers were interviewed, revealing that 79.4% of gardens were profit-oriented. Gardens had inadequate setbacks (mean 1.45 m) from roads, leading to off-street parking and traffic congestion. Only 20% of horticulturists aimed to improve urban aesthetics, indicating a need for urban planners to educate them to prioritize urban aesthetics over economic gain.

This qualitative study in Wolenchiti town, Ethiopia, identified determinants of livelihood strategies among female household heads. Major activities included petty trading, domestic services, daily labor, prostitution, and urban agriculture. Demographic factors like age and household size, and socioeconomic factors such as access to financial, human, social, physical, and natural capital, were found to be leading determinants.

In Ezibeleni near Queenstown, Eastern Cape, South Africa, a sustainable-development framework was used to gather empirical findings on vegetable crop cultivation, covering duration of crop consumption, the value of produce to households, environmental benefits, and social/psychological benefits. Both the scale of cultivation and the benefits obtained were found to be modest, reinforcing prior studies that focused on the actual practice of urban agriculture rather than its hypothetical potential.

An overview report based on the 2007-2008 CSO/MACO/FSRP food consumption survey in urban Lusaka, Kitwe, Mansa and Kasama, Zambia. It states that policies promoting demand-driven smallholder agriculture and improved urban food marketing system performance in Sub-Saharan Africa need to be grounded in careful food demand analysis, and that governments, donors and policymakers require an up-to-date understanding of urban consumption patterns, including the extent of and constraints on urban agriculture for household consumption and cash income. This excerpt does not present specific survey results.

Erastus K. Kang’ethe, Delia Grace, Thomas F. Randolph · East African Medical Journal · East Africa

This study synthesizes current knowledge on urban agriculture (UA) in East Africa, focusing on its human health impact. It identifies UA as an important source of food security, but notes that many zoonotic and food-borne diseases are associated with it, with a lack of evidence on human health impact and management. Major constraints include illegality and limited access to inputs and markets, indicating a need for more research to understand both positive and negative health impacts.

Anselm A. Enete, Anthonia Ifeyinwa Achike · Outlook on Agriculture · Nigeria (Ohafia)

A study comparing rural and urban farmers in Ohafia, southeast Nigeria, found that while urban farmers used significantly more purchased inputs than rural farmers, their output was significantly lower. This was attributed to urban farmers being poor and undercapitalized, preventing them from using adequate purchased inputs to maintain soil nutrients. The findings suggest that for urban agriculture to address urban food insecurity, the urban poor require sufficient financial empowerment.

I A Olugbenga, O. T. Adejumo · Eastern Africa Journal of Rural Development · Africa

This paper examined potential land and water resources for urban agriculture in metropolitan Lagos. While urban agriculture positively influences the financial empowerment of the urban poor, who spend 90% of their income on food, the land ownership system in Lagos complicates land access. The study identified 1,197 and 28,890 hectares of potential land resources under Federal, State, and private ownership, respectively.

C.J. Arene, G.I.O. Mbata · Agricultural Economics (Zemědělská ekonomika) · Nigeria (Abuja)

This study analyzed the profitability of urban agriculture using metropolitan organic waste in Abuja, Nigeria. Results indicated that the enterprise is profitable, with output price being the most important determinant of maximum variable profit. The study also showed that farmers' education level, age, per capita farm income, and household size are important determinants for choosing urban agriculture for food security and environmental quality improvement.

Dick Foeken · · Africa

This study analyzed the relationship between urban policy and the practice of urban agriculture by the poor, based on two studies in Nakuru Municipality, Kenya, and Morogoro and Mbeya Municipalities, Tanzania. The legal and policy setting in these towns was found to be confusing, and the poor generally do not benefit from policy measures, if policies exist at all.

CJ Arene, G.I.O. Mbata · Agro-Science · Nigeria (Abuja)

This study analyzed the profitability of urban agriculture using metropolitan organic waste in Abuja, Nigeria. The enterprise was found to be profitable, with output price being the most significant determinant of variable profit, while other price factors were not significant. Farmer's education level, age, per capita farm income, and household size were identified as important determinants for choosing urban agriculture and influencing willingness to pay for it.

This study assessed the general performance and challenges of Micro and Small Scale Associations (MSSAs) in Wolkite and Boutajira city administrations, using questionnaires for 92 operators and interviews with 5 officials. Findings revealed that government supports have not ensured the sustainability of these associations, and service provision is not aligned with national strategy. MSSAs exhibit high closure rates, member dropout, fail to create long-term jobs, and show insignificant women's participation.

I. Ogunlade, O. I. Oladele, A. A. Falaki · University of Dar es Salaam Library Journal · Nigeria

This study investigated the socio-economic characteristics, information needs, and seeking behavior of 100 urban farmers in Ilorin metropolis, Kwara State, Nigeria, using a structured questionnaire. It found that urban farming was a supplementary activity for highly literate individuals, with farms mainly within the city and more animal than crop production. The study suggested that urban farmers could achieve better results if technical and financial support were provided, and recommended official government recognition for urban farming.

This study investigated the adoption rates of smart agriculture technologies among urban farming communities in Lagos, Nigeria. A survey questionnaire was distributed to 200 urban farmers across Lagos, revealing that 78% of respondents had adopted at least one smart agriculture technology. Drip irrigation systems were the most popular, adopted by 35% of farmers. The findings indicate significant interest and initial success in adopting these technologies in Lagos.

M. B. David · African Affairs · Kenya

This study on urban agriculture in the Kenyan town of Nakuru illustrates health and environmental problems associated with keeping livestock in urban areas, the small size of plots cultivated, and the dependence of urban households on rural sources of food. These findings were observed in the context of economic hardships occasioned by structural adjustment programmes since the 1980s.

This study characterizes urban and peri-urban agriculture in Yaoundé, Cameroon, that has emerged amid rapid urbanization unaccompanied by economic growth, analyzing the interaction of actor types, space types, crops, products, and average incomes. The analysis found this agriculture employs close to 2,000 people, mostly young people and especially women with an average age of 35, concentrated on land under heavy pressure — marshy lowlands, foot of slopes, and roadsides. Crops were mainly vegetables, food staples, and flowers, varying across the urban ring, peri-urban zone, and rural hinterland. Marketing occurred through long, short, and direct circuits, with prices set by demand rather than fixed in advance. Profitability analysis of celery, ndolé, and black nightshade accounts found an average daily gain of about three euros per producer, and some market gardeners reported preferring to stay in their gardens rather than take a roughly 75-euro/month wage job; the study also found no legal or regulatory framework governing the activity, and no law authorizing it.

Alex Thornton, Etienne Nel · Africanus Journal of Development Studies · South Africa (Peddie)

This study investigated the significance of urban and peri-urban agriculture (UPA) as a livelihoods strategy in Peddie, Eastern Cape province, South Africa, based on a PhD study. The findings indicate that UPA is not as significant or widely practiced as often assumed, despite its potential to address food insecurity and generate income. Its development has been slowed by various structural historical and socioeconomic barriers, limiting its current impact.

B. J. Njokwe, Maxwell Mudhara · · South Africa

In Msunduzi Municipality, South Africa, urban residents, particularly women and children, engage in agriculture due to poverty and high unemployment rates. This practice, often carried over from rural community gardens, helps alleviate poverty, especially for families affected by HIV/Aids who lack income.

Fasil Desta, Kebede Mekonnen, Girma Abayor, Ayehu Alemayehu · Zenodo (CERN European Organization for Nuclear Research) · Ethiopia

Community garden adoption and economic empowerment in Ethiopian urban slums were analyzed using a mixed-methods approach incorporating surveys and focus group discussions. Community gardens were adopted by 45% of surveyed households, with higher adoption rates observed in areas with better access to water sources. The study highlights the potential for community gardens as an inclusive strategy for improving food security and economic conditions in Ethiopian slums.

Francis Owusu · Journal of Planning Education and Research · Africa

This paper proposes the "multiple modes of livelihood" (MML) approach to understand contemporary livelihood strategies in African cities, which often involve participation in multiple economic activities across formal and informal sectors. The study presents evidence of the magnitude of this strategy and the types of activities undertaken. It suggests that the importance of urban agriculture, among other factors, indicates a need to indigenize urban planning in Africa.

A sample survey of 242 urban vegetable farmers conducted through March 2006 examined production efficiency and its determinants in fadama agriculture — flood-plain cropping of short-duration crops on low-lying, seasonally flooded land — in urban southwestern Nigeria, using a stochastic frontier model. Mean farm size was 0.54 hectares and mean producer age was 42.6 years, while mean technical efficiency was only 74.36%, with the main sources of inefficiency identified as labor employment and the use of land and seed/cultivar resources; the most common crop combination was Telfaria occidentale, Amaranthus hybridus and Zea mays.
