Urbanization-Triggered Industrial Development in Kenya’s Peri-Urban Areas and Its Implications on Food Security: The Case of Kiambu County
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.

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.

A study of 149 respondents in Nairobi County examined urban and peri-urban agricultural practices, finding composting and open field farming popular but not the most profitable. More profitable practices like cattle rearing and mushroom farming were unpopular due to expensive inputs and specialized skills. The study indicates that popular practices are less profitable, highlighting a need for transformation towards controlled environment agriculture with policy support.

2021Juliana Ojochide Olori, Ogechi Cordelia Nwahia, F. Siewe · Agricultural Social Economic Journal · Nigeria (Abuja)
A study analyzed savings mobilization for poverty alleviation among 185 peri-urban farming households in Kwali and Bwari Area Councils, Abuja, Nigeria, using cross-sectional primary data. The analysis revealed a poverty incidence of 49%, a poverty depth of 28%, and a poverty severity of 56% among the households. Findings indicated that primary occupation and education reduced the likelihood of not being poor but increased the likelihood of being very poor.

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.

2018Fabrice Dossa · Agricultural Research & Technology Open Access Journal · Benin
A study in southern Benin surveyed 60 onion farmers across three municipalities (Grand-Popo, Cotonou, Sm-Kpodji) using quantitative and qualitative methods. It found onion production to be financially profitable, with performance enhanced by age, experience, and producer group membership, and improving socio-economic and food situations. However, significant constraints include financial, institutional, organizational, property, and production-related issues.

2015Martin Dyer, Richard M. Mills, Beatrice Conradie, Jenifer Piesse · Open University of Cape Town (University of Cape Town) · South Africa (Cape Town)
This paper investigates the efficiency relationships between inputs and outputs of urban micro-farms in two Cape Town townships, Nyanga and Khayelitsha. Data Envelopment Analysis (DEA) applied to 33 producers supplying a social enterprise box scheme revealed an average overall efficiency of 72.4%. Overall efficiency was negatively correlated with land holdings and the use of compost and seedlings, indicating efficiency losses with greater input quantities. Furthermore, it was not shown that mulching or operator experience increases profitability.

2014Taibat Lawanson, Olabode Orelaja, Michael Simire · African Journal of Science Technology Innovation and Development · Nigeria (Lagos)
This case study investigated the effects of climate change on agricultural activities in the Igbe Farming Community, Lagos, Nigeria, by surveying 161 farmers. The study found that most migrant farmers leased plots annually or biennially and made marginal profits of $200 to $350 per farming cycle. Erratic weather patterns and aggressive urban growth were major challenges, leading 48% of respondents to engage in informal enterprises.
