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.

James 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.

Logistic regression and thematic content analysis revealed that evicted households are approximately 72.7% less likely to achieve economic security compared to non-evicted households. The study concluded significant differences in household economic capital security between the two groups.

Mahacla Odongo, Caleb Mireri, Peter Mwangi · Environmental Technology and Science Journal · Kenya (Nairobi)

The Nairobi River riparian reserve in Kenya has undergone immense land use and land cover changes over the past 20 years due to urban development. A survey of 650 respondents revealed that urban agricultural activities dominated the upper segment at 69%, commercial ventures constituted 79% of the middle segment, and residential usage comprised 89% in the lower segment. These activities caused significant degradation from crop cultivation of river slopes, pollution infiltration, and loss of biodiversity, indicating a severe depletion of the riparian space's functions.

Emmanuel Ndhlovu · Discover Sustainability · South Africa

This article critically analyzed food system policies and actions in four South African cities, drawing from grey and academic documents. It found that the government is failing to achieve food security, with approximately 58 million people facing food insecurity in 2023. The study concludes that transforming South African food systems requires coherent policies, shortened supply chains, integration of food into urban planning, and increased support for farmers, among other actions.

Paule 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.

Fuchaka Waswa, Duncan Gichabe, Ruth Kahuthıa-Gathu · Journal of the Kenya National Commission for UNESCO · Kenya (Ruiru)

This study investigated land use changes in Ruiru Sub-County, Kenya, from 1988 to 2024 using GIS. By 2024, agricultural land had decreased by 45.62%, while urban land use increased by 509%, and bare/rocky areas rose by 133% due to abandoned stone mining. The decline in agricultural land leads to reduced industrial crop areas and a shift to leafy vegetables, with an expected increase in agro-chemical use in intensive peri-urban farming.
