Read the passage below carefully:
Urban agriculture is rapidly transforming municipal food security across sub-Saharan Africa. In cities like Ibadan and Dar es Salaam, rooftop gardening and backyard farming provide fresh produce to low-income households while reducing urban heat island effects. Proponents emphasize that localized cultivation reduces dependency on fragile rural supply chains and lowers transportation emissions. However, agricultural economists caution that widespread urban farming faces severe challenges, including soil contamination from industrial runoff and insecure land tenure. Despite these logistical hurdles, municipal authorities are beginning to integrate urban farming zones into master urban plans, recognizing its dual benefit of environmental resilience and economic relief.
