Urban agriculture in Ethiopia is a vital livelihood strategy, contributing to employment, income, and food security. Despite its significant contributions to GDP and urban employment, its potential is insufficiently utilized due to structural obstacles. These hurdles include restricted access to land and water, deficient regulatory frameworks, poor institutional support, social stigma, and environmental risks, and it is insufficiently acknowledged in urban development strategies.

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.
