Assessing the Potential of Rooftop and Wall-Based Urban Agriculture for Food Security Enhancement in Gasabo District, City of Kigali, Rwanda
Abstract
This study evaluates the potential of rooftop and wall-based urban agriculture to enhance food security in the Gasabo District of Kigali, Rwanda. It combines GIS and remote sensing techniques to map suitable urban farming spaces and uses a stratified sampling technique to select 400 household heads for assessment using the Household Food Insecurity Access Scale (HFIAS). The findings show that 41.5% of the households experience moderate to severe food insecurity, and approximately 32% of rooftops and walls are structurally appropriate for urban agriculture. While 57.8% of households express willingness to adopt rooftop or wall gardening, 67.4% cite structural and financial constraints. A strong positive correlation (r = 0.68, p < 0.01) was observed between urban agriculture adoption and improved food security. The study recommends prioritising high-suitability sectors such as Kinyinya and Ndera for pilot projects and promoting lightweight hydroponic and vertical farming systems tailored to urban structures. These findings support the integration of urban agriculture into Kigali’s urban planning to enhance food resilience and sustainability
