A 2025 study from South Africa's Western Cape used propensity score matching on data from 220 households — those participating in Department of Agriculture-funded backyard garden projects plus a control group — to assess urban agriculture's contribution to household food security. Households engaged in urban agriculture benefited from greater dietary diversity and income from selling produce, but the study found no significant positive contribution of urban agriculture to food security.

This study investigated the links between peri-urban households' engagement in agriculture, their dietary behavior, and their children's nutrition outcomes around Eldoret, Kenya. Survey data collected from 518 households indicated that peri-urban households involved in agriculture, particularly crop growing and sales, had more diverse and nutritious diets than non-engaged households. However, a significant improvement in children’s health outcomes in these households was observed only when coupled with improved water, sanitation, and hygiene conditions.

This narrative review searched Scopus, the Directory of Open Access Journals, Web of Science, Google Scholar and Academic Search (EBSCO) using terms including "urban farming," "urban agriculture" and "climate change" to synthesize literature on climate change's effects on urban agriculture in sub-Saharan African cities. While reviewed studies agree that climate change affects urban agriculture from production through processing, storage and distribution, integrated literature on the topic remains scarce, and the extent and magnitude of impacts differ by region, meaning adaptation and mitigation strategies cannot be applied universally and must instead be context-specific.

In Nairobi, Kenya, stratified random sampling, field surveys and questionnaires were used to identify existing water sources and wastewater treatment systems and their reuse status, in an investigation of the potential for eco-friendly urban and peri-urban agriculture (EcoUPA). Of the 300 respondents interviewed, only 66 (22%) reused wastewater, and only 54 of those reused it for crop production. Ninety-eight respondents (33%) wanted information on wastewater treatment systems allowing reuse, and 124 (41%) were willing to pay for a new system. The findings indicate that limited urban water sources constrain the spread of urban and peri-urban agriculture.

A study in Ondo State, Nigeria, examined food security among peri-urban farming households using descriptive statistics, a food security index, logistic regression, and the coping strategy use index. It found that 54.4% of households were food insecure, with a 62% calorie deficit for these households, while 45.6% were food secure, exceeding calorie requirements by 48%. Household income positively affected food security, while household size had a negative effect.

A study surveyed 700 randomly selected households across Kano (Nigeria), Bobo Dioulasso (Burkina Faso), and Sikasso (Mali) to explore the relationship between household socioeconomic status (SES) and participation in urban and peri-urban agriculture (UPA). The results showed no significant differences in UPA participation rates across socioeconomic groups. Instead, UPA participation was significantly and positively related to household size.

This study investigated the significance of urban and peri-urban agriculture (UPA) as a livelihoods strategy in Peddie, Eastern Cape province, South Africa, based on a PhD study. The findings indicate that UPA is not as significant or widely practiced as often assumed, despite its potential to address food insecurity and generate income. Its development has been slowed by various structural historical and socioeconomic barriers, limiting its current impact.
