Climate change impact on urban food gardens: implications for adaptation strategies and food and nutrition security in townships in Pietermaritzburg Kwazulu-Natal, South Africa
2026Nthabeleng Tamako, Joyce Chitja · Agriculture & Food Security · South Africa
This study examined the impact of climate change on urban food gardens in Sobantu and Mpophomeni townships in Pietermaritzburg, KwaZulu-Natal, South Africa. Face-to-face interviews with 103 randomly selected participants revealed that climate change disproportionately affects resource-limited urban farmers, leading to erratic rainfall, pests, and natural disasters. Elevated temperatures, shifting weather patterns, and new pests and diseases significantly impact food gardens, affecting seed and crop selection and contributing to food insecurity.

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.

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.

2023Mallika Sardeshpande, Charlie M. Shackleton · People and Nature · South Africa
This study interviewed 80 urban foragers in four cities in South Africa's eastern coastal region to understand urban foraging in a developing nation context. Foragers began foraging in childhood, viewing it as a cultural and recreational activity, but formal green spaces were not used for foraging and were perceived as poorly provisioned in urban planning. This indicates a lack of governance in urban planning regarding foraging.
