2026Abie Assres Fenta, Habtie Anmaw · Discover Sustainability · Ethiopia (Debre Markos)
This qualitative study explored the adaptive livelihood strategies of evicted peri-urban farmers around the metropolis of Debre Markos, Ethiopia. Findings confirmed that farmers tend to hand over their land with insufficient compensation and are compelled to adapt to new livelihoods after losing farmlands. Many displaced young farmers experienced bankruptcy in new businesses due to a lack of business skills, and aged displaced farmers faced challenges adapting to new ways of life. The government did not provide adequate attention to training evicted farmers in technical, financial, and business planning.

2025James S. Kaba, Joseph Mutungi, Gladys Rotich · International Journal of Research and Innovation in Social Science · Kenya
This study examined the implications of urbanization-triggered industrial development on food security in Kiambu County, Kenya, neighboring Nairobi. Through mixed qualitative and survey-based data collection and analysis from 400 respondents including farmers, agricultural workers, urban planners, and government officials, the study found an 85% increase in farmland conversion to industries over the last 20 years. This industrialization contributed to a decline in food production, as reported by 65% of respondents who left farming for industrial jobs. Land-use transformations have resulted in fewer farms involved in agriculture and the replacement of old food systems.

2025Etefa Tilahun Ashine · International Journal of Agricultural Economics · Ethiopia
This review examines the challenges and opportunities of urban agriculture in Ethiopia, where urbanization and living costs are rising. Key challenges include limited access to land, irrigation water, and financial institutions, as well as high prices for fertilizers and pesticides, and climate variability affecting crop yields. Opportunities include strong market demand for products, employment creation for youth and women, and additional income generation for producers. The study concludes that stronger policy support and investment are needed to enhance urban agriculture's contribution.

2025Paule Moustier, Jacques Pagès · HAL (Le Centre pour la Communication Scientifique Directe) · Africa
This study examined peri-urban agriculture in Africa, identifying it as a significant income and food source for the urban poor, but subject to constraints, primarily land pressure. Analysis of the vegetable supply chain in Brazzaville showed rural and peri-urban areas are complementary, with different types of vegetables originating from each. Land constraints, transport, access to inputs, and technical assistance are crucial factors determining production location. Historical analysis invalidates hypotheses of linear decline or development through intensification for peri-urban agriculture.

2024Sylvia Leith-Ross · · Nigeria
This text describes Owerri Town, Nigeria, as a native community in a transition stage, simultaneously urban and agricultural. The author initially chose Owerri for convenience but later recognized its unique character compared to other towns like Aba. The town maintained contact with the outside world and government, while retaining its own distinct life. The author observed the town's life at various times throughout the year.
CommunityUrban–rural linkageEconomicsImpacts of urbanization on food security in Ethiopia. A review with empirical evidence
2024Mekonen Getachew Abebe · Journal of Agriculture and Food Research · Ethiopia
This review examined empirical evidence on the impacts of urbanization on food security in Ethiopia. The review showed that urbanization compromises all dimensions of food security through reductions in arable land and its productivity, waste dumping, biodiversity depletion, and water and soil pollution. Rapid urbanization leads to reduced production and higher food prices, resulting in a very high prevalence of food insecurity in Ethiopian urban areas. The review noted that Ethiopia has not implemented solutions like urban agriculture to its full potential.
Food sovereignty & justiceEconomicsUrban–rural linkageChapter 2. Stone by stone: Women's quotidian farm labor and the construction of the Khutwaneng farmscape in Bokoni, South Africa
2024Maria H. Schoeman · Archeological Papers of the American Anthropological Association · South Africa
In Bokoni, northeastern South Africa, stone-walled towns flourished from the late 15th to early 19th centuries, and lidar data confirmed the presence of terraced fields in Khutwaneng from the 17th to early 19th centuries. All homesteads in this town had adjacent terraced gardens or fields, suggesting that urban farming was an entrenched component of Bokoni's urban life. Historically, women performed daily farming duties in southern Africa, and this was likely also the case in Bokoni.
