Eric Antwi Ofosu · · Sub-Saharan Africa

The conditions that led to large public investment in irrigation in the second half of the 20th century have changed radically, requiring substantial shifts in irrigation strategies today. The mid-1980s saw the rapid development of shallow tubewells and conjunctive use of surface and groundwater in India and Pakistan due to affordable drilling and pumping technologies. Similarly, the 1990s witnessed a substantial rise in private irrigated peri-urban agriculture in sub-Saharan Africa, driven by increased demand for fresh fruits and vegetables from growing cities.

Jonathan Crush, Bruce Frayne · Journal of Southern African Studies · Southern Africa

This article reviews urban food sources in Southern African cities, focusing on supermarket expansion, its impact on informal food suppliers, and the relative insignificance of urban agriculture for poor urban households. Findings from an eleven-city survey by AFSUN are presented, highlighting that urban agriculture has limited significance in addressing urban food insecurity in the region.

Messay Mulugeta Tefera · Journal of sustainable development in Africa · Ethiopia (Adama)

This study assessed the role of urban agriculture in attaining urban food security for smallholders in Adama town, central Ethiopia. Findings confirmed that urban agriculture plays a significant role in urban household food security. Over 40% of the surveyed households obtained well over the nationally set minimum dietary energy requirement solely from their urban farmlands.

Mohammed Murtala Ruma, Abdullahi Usman Sheikh · African Journal of Environmental Science and Technology · Nigeria (Katsina)

This paper investigated the status of wastewater reuse in urban farming in Katsina, Nigeria, by interviewing 120 households out of 250 registered with the Katsina Urban Planning Authority. It was found that wastewater reuse in urban farming is a full-time, sole income earner for many households and is indispensable for this semi-arid city. However, the urban planning process has not officially recognized or given attention to this important activity.

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.

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.

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.

BF Salahu, TO Dauda · Moor Journal of Agricultural Research · Nigeria

The food security status of farming households in Ibadan metropolis, Nigeria, was assessed using 89 questionnaires. The study analyzed urban farming and food security factors (energy and protein levels). Education related to urban farming practices was found to influence the food security status of the respondents.

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.

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.

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.

Jonathan Crush, Miriam Grant, Bruce Frayne, Southern African Migration · · Africa

This literature review examines the complex interactions between migration, HIV/AIDS, and urban food security in Southern and Eastern Africa, noting that these links are poorly researched and understood. It highlights that while past research focused on urban acquisition and production, less attention has been paid to rural-urban linkages and their embedment in migration systems. Recent studies indicate that strong rural-urban connections, including increasing direct food transfers from rural to urban households, are crucial for urban households' coping strategies.

This report provides a state-of-the-art overview of irrigated urban agriculture in the West African sub-region. The overview is based on a comprehensive literature review supported by the results of three IWMI FAO projects.

E. Omomoh, C. O. Adeofun · · Nigeria

This study assessed urban agricultural land use changes in Jos-Bukuru, Nigeria, between 1961 and 2002 using a geospatial information system. It found that agricultural land use substantially increased from 1961 to 1986. However, between 1986 and 2002, approximately 63% of agricultural land was lost, with about 68% of this loss attributed to urban development. The study concludes that while urban spatial expansion is increasing, agricultural land use is decreasing.

Wilfred Subbo · University of Nairobi Research Archive (University of Nairobi) · Kenya (Nairobi)

This paper discusses strategies for sustainable food production in Nairobi, Kenya, aiming to supplement rural food supplies and improve urban health through fresh, accessible food. It argues for discarding the attitude that food can only be produced in rural areas and explores the linkage between sanitation and urban food security. Additionally, the paper offers suggestions for mechanisms to increase food production in Nairobi.

This chapter provides an overview of international efforts and initiatives to strengthen urban and periurban agriculture, with special reference to related networks in Africa.

Dick Foeken, Samuel Owuor · · Kenya

A 2001 study examines "multi-spatial livelihood" households — those with a livelihood foothold in both urban and rural areas — from the urban perspective, based on Nakuru Town, Kenya. According to 1999 survey data, over 60% of Nakuru households can be considered to have a multi-spatial livelihood. While one-adult and low-income households are relatively under-represented in the survey, multi-spatial livelihoods may be particularly important for the food security of the latter group. However, the results indicate that rural farming by urban dwellers should be understood mainly in terms of "opportunity," in contrast to urban farming, which is framed in terms of "necessity."

Paule Moustier · Agritrop (Cirad) · Africa

Case studies conducted in Africa on urban household food supply systems evaluated the relative roles of urban and rural agriculture. These studies highlighted a strong complementarity between urban and rural sources in terms of products and periods, linking these observations to differences in production and marketing systems. To stabilize urban food supply in quantity and quality, support programs for farmers and traders should target both urban/peri-urban and rural areas in a differentiated but articulated manner.

Tony Binns, Kenneth Lynch · Journal of International Development · Africa

This paper addresses the escalating demand for fresh foodstuffs in rapidly urbanizing Sub-Saharan Africa, where urban agriculture is a widespread activity. Based on a literature survey and empirical evidence from Kano and Dar es Salaam, it presents a framework for analyzing urban agriculture. The study proposes policy recommendations aimed at enhancing the future sustainability of urban agriculture.

P. Anyang’ Nyong’o, Donald B. Freeman · Canadian Journal of African Studies / Revue canadienne des études africaines · Kenya

This study by Donald Freeman examined informal urban agriculture in Nairobi, Kenya, through on-site surveys of 618 small-scale cultivators in ten different areas. It describes urban farmers, their land use practices, and crops, and discusses the development and significance of urban agriculture within Kenya's social and economic development. The findings suggest a need to redefine urban productive activities in the Third World to include basic food production in cities.

David Drakakis‐Smith · Geografiska Annaler Series B Human Geography · Africa

This paper focused on the impact of structural adjustment programs on the urban poor in Africa, specifically examining the urban food system in Harare, Zimbabwe. In Harare, food retailing is largely structured through supermarkets, which keeps costs high for the poor. While the informal sector has expanded, it remains relatively restricted and unorganized compared to Asian cities. Consequently, urban agriculture has grown extensively in house-gardens and illegally in the urban periphery, yet there is little coordinated or positive policy response from urban authorities.

Christian M. Rogerson · Development Southern Africa · South Africa

This paper argues that urban agriculture is an important issue for South African policymakers, noting an increase in urban food gardening and cultivation of vacant land in South Africa's metropolitan peripheries. It reviews research on informal agriculture in Asian and African cities to offer suggestions for policy debates and research in South Africa.

Lee M · PubMed · Ethiopia

In Ethiopia, urban agriculture faces significant challenges due to government disapproval of public land use for farming and difficulty in obtaining credit. A 1983 survey in Addis Ababa found that 17% of 1352 households produced their own food on less than 25 sq. meters, with 90% of non-farmers citing lack of land. Despite urban agricultural cooperatives demonstrating 70% higher member income, their lack of government legalization prevents access to loans for productivity improvement.
