Due to rapid urbanisation, food systems in sub-Saharan African cities are increasingly under pressure. Through the lens of a foodshed, this paper quantitatively analyses the spatial extent of the food provisioning area for consumers of different socio-economic status in Kampala (Uganda). Based on a primary dataset of surveys with households and food vendors, we map the foodshed by registering where consumers obtain their food, and the origin of where it is grown. We show that 50% of the food consumed in the city originates from within a 120 km proximity to Kampala, including 10% from within the city itself. At present, urban agricultural activities are twice as important as international imports for the urban food provision. Established, high-income urban dwellers have a more local foodshed due to their broad participation in urban agriculture, while low-income newcomers rely heavily on retailers who source food from rural Uganda.
由于快速城市化,撒哈拉以南非洲城市的粮食系统面临越来越大的压力。本文从食物 shed 的角度,定量分析了坎帕拉(乌干达)不同社会经济地位消费者的食物供应区域的空间范围。基于对家庭和食品摊贩的调查的原始数据集,我们通过记录消费者获取食物的地点以及食物的种植来源来绘制食物 shed 地图。我们表明,该市 50% 的食物来自距离坎帕拉 120 公里以内的地区,其中 10% 来自城市本身。目前,城市农业活动对城市食物供应的重要性是国际进口的两倍。由于广泛参与城市农业,既定的高收入城市居民有更本地化的食物 shed,而低收入新居民严重依赖从乌干达农村采购食物的零售商。
