This qualitative study explored the technical, institutional, and commercial aspects of urban agriculture (UA) in two Ethiopian secondary towns, Dessie and Kombolcha, through 68 key informant interviews and 11 focus group discussions. It found that nearly 90% of local leafy vegetables are sourced via UA, but insecure land rights, limited policy support, and informal trading systems hinder its impact. Informal markets also cause post-harvest losses, disproportionately affecting women.

A study of the "Ceinture verte" (Green Belt) in Ouagadougou, Burkina Faso, as a nature-based response to climate adaptation. Established in 1976 and relaunched in 2018, the initiative combines forestry development with urban agriculture, aiming to contain urban sprawl, improve the local climate and strengthen the capital's resilience. The study combined a diachronic analysis of Landsat imagery from 1984-2024 with interviews of institutional actors, associative partners and direct beneficiaries. Results show significant contributions — expansion of dense vegetation in some areas, a perceived improvement in air quality, the creation of income-generating market-gardening activities, and the inclusion of vulnerable populations — but also reveal strong constraints: illegal occupations covering a significant share of the land, fragmented governance, limited access to water, security fragility, and still-limited involvement of local residents. The study discusses the feasibility of a trajectory to 2050 between an optimistic scenario conditional on structural reforms and a critical scenario underscoring current limits, and offers lessons transferable to urban adaptation policies in other Sahelian metropolises.

In north-west Ethiopia, a study analyzed urban expansion driving factors, compensation, and livelihood coping strategies of displaced farmers surrounding medium-sized towns. Primary data was collected through 350 survey questionnaires, two FGDs, and six key informant interviews. Findings revealed that compensation was mostly cash-based, and social relationships and community values decreased after displacement. The study suggests a need for proper urban land governance with a participatory approach that includes farmers, and for appropriate urban planning and land policy to improve urban land use efficiency.

This study descriptively investigated the vulnerability to shocks and pressures of the Philippi Horticultural Area (PHA), a key urban food-producing region in Cape Town, South Africa. Data were collected through surveys with stakeholders from government, the private sector, NGOs, private individuals, and informal settlers. Key findings revealed insufficient governance commitment, a lack of multi-stakeholder collaboration, and the growing threat of urban development on agricultural land.

Tesfay, 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.

Land Use/Land Cover (LULC) dynamics were analyzed in four Ethiopian cities—Addis Ababa, Hawassa, Bahir Dar, and Adama—over 17 years from 2006 to 2022. SPOT 5 and Sentinel satellite imagery, key informant interviews, focus group discussions, and field observations were used. Findings revealed a rapid expansion of urban built-up areas, primarily at the expense of peri-urban horticultural lands, which has an adverse impact on the sustainability of urban agriculture.

Market gardening in Kinshasa's urban and peri-urban areas faces multiple constraints, including land insecurity, low natural soil fertility, the incidence of diseases and pests, weak technical support, climate hazards, poor input supply, and problematic marketing systems. These constraints limit yields in production sites and hinder the development of market gardening activities.

This research in the Arrondissement of Zinvié, Africa, investigated agricultural land governance through surveys of 109 people and field observations. Findings indicate rapid urbanization is causing anarchic land occupation and uncontrolled consumption of agricultural space, with renting being the dominant land access mode (50%). From 2010 to 2020, cultivable land decreased by 517.69 hectares due to urbanization, highlighting significant governance challenges.

A 2022 study analyzed the peri-urban agrifood system of the Sousse urban agglomeration, one of the most important in Tunisia, from a landscape perspective. It finds that clearly deficient regulations combined with uncontrolled urban development, together with intersecting political, environmental and economic factors, are threatening the survival of a traditional, largely family-based agricultural model built on mixed or polyculture production with predominant olive groves — a model the study describes as vital to the economic maintenance of many families and to food security. Using the Landscape Character Assessment methodology, the study proposes a landscape-project tool to strengthen the resilience and sustainability of peri-urban agriculture and prevent the loss of landscape heritage. It also points to the importance of integrating green infrastructure into land-use planning and to the need to promote Agricultural Parks, a protected status already recognized in Spain and other countries, putting forward specific proposals for the Sousse peri-urban agricultural landscape while insisting on the need to reform current forms of governance.

A mixed-methods study in Wa Municipality, Ghana, examined how peri-urban agricultural land use change affected farmers' food security, surveying 235 smallholder farmers with questionnaires, interviews and GIS-based historical data. Over the past three decades, peri-urban agricultural land was drastically lost to residential and infrastructural development, and this land use change resulted in food insecurity, with most smallholder farmers unable to meet their food needs over the past decade.

A study of Bouaké, Côte d'Ivoire, analyzes new land-use dynamics around intra-urban shallow lowlands (bas-fonds) and their effects on market gardening. It finds that rising stakes over these lowlands have drawn in new actors, reducing cultivated areas and making market gardening more unstable and casualized. The operating rules for the floodplain plots previously allocated to gardeners have been redefined, and public servitude land and unbuilt areas are increasingly subject to illegal land transactions and unauthorized construction — indicating a breakdown in land governance and the neglect of urban agriculture within public policy and city management in Côte d'Ivoire.

This paper critically examined existing literature on peri-urban agriculture in Southern Africa, arguing it is a viable livelihood response to feeding urban residents. Despite its potential, the literature indicates that peri-urban agriculture does not play a major role in Southern Africa. The study concluded that a lack of political will and weak or absent policy frameworks, stemming from capacity deficits, hinder its promotion.

This 2011 study in Bondo Sub County, Kenya, assessed the integration of urban and peri-urban agriculture (UPUagr) into urban planning, using a descriptive survey design with 368 households and 248 traders. A major challenge identified was the lack of supportive local policy and legal frameworks for UPUagr, and problems with its integration into broader urban development plans. The study found that UPUagr complemented rural agriculture and increased food system efficiency.

A study assessed the process of built-up property formation in Ethiopia's peri-urban areas. Through analysis of survey results and a review of relevant literature, the study elucidated the processes of peri-urbanization and new property development. It demonstrated that both formal (legal) and informal methods are equally important in converting peri-urban agricultural lands into urban built-up non-agricultural properties. This process creates intense competition for land between agriculture and non-agriculture, leading to the emergence of new property rights and the dissolution of existing traditional rights.

In Ethiopia, all land is state-owned and granted to residents only as a holding right, with separate systems for rural and urban areas. Focusing on peri-urban agricultural land under growing pressure from urbanisation, this desk-review study analyzed existing survey research together with property-rights literature, theory, and current land-rights laws and policies. It found that new recipients of peri-urban land under the urban land-lease system obtain better and more extensive bundles of land rights than the indigenous, local peri-urban landholders who previously held that land.

A study in the Kuje area council of Abuja, Nigeria, used questionnaires and multi-temporal satellite images from 1975–2010 to assess urban encroachment on agricultural lands. It found that urban encroachment into agricultural lands is occurring at an alarming rate of 15.7 km² annually, resulting in a total loss of 509 km² of agricultural land to urbanization over 35 years.

This paper critiques the assertion that commercialization of smallholder agriculture poses dangers for sustainable rangeland management in South Africa. It argues that a range of policy options are required, including commercialization and subsistence farming, large-scale and smallholder farming, various land tenure options, rural and peri-urban farming, and part-time farming. The case of municipal commonage land is used to demonstrate the effectiveness of flexible policy options regarding land ownership, farming scale, and the social nature of farming, but it is noted that effective institutional development is a key requirement in all cases.

A 2003 paper examined the links between urban solid waste management and peri-urban agriculture in Bamako and Ouagadougou. Farmers near both cities value urban waste as an organic matter source and are willing to pay for it, but uncertain land tenure provides little incentive for safe disposal of dangerous elements in solid waste. Current plans to eliminate this recycling practice and promote large-scale composting are noted to be too costly for farmers, creating an incentive for illicit waste acquisition.

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.
