在快速城市化的撒哈拉以南非洲(SSA)，不断变化的城市食品系统预计将影响家庭获取食品的方式。虽然重大研究和政策努力涉及在城市-区域粮食系统的背景下进行粮食生产以支持粮食安全，但城市粮食系统的复杂性受到的关注较少，特别是在全球的二线城市。利用2019年在肯尼亚4个城市和赞比亚14个城市收集的家庭调查数据，我们研究了关键食品零售点的家庭食品采购模式。家庭主要从露天市场和小贩那里购买食品，只有一小部分家庭从超市购买食品。18个城市的城市人口规模、面积和连通性的差异呈现出四种城市类型的集群，这些城市类型塑造了家庭在食品零售点的食品获取和购买模式。尽管越来越多的人认为超市和西方饮食将主导南沙的城市食品体系，但我们的发现表明，未来几年，中低收入家庭将继续在南沙二级城市的露天市场购买食品。对这些城市家庭采购模式的关注可以为城市规划和治理的优先事项提供信息，以确保SSA的粮食系统能够满足城市粮食安全需求。
In a rapidly urbanizing sub-Saharan Africa (SSA), changing urban food systems are expected to affect the ways in which households access food. While significant research and policy efforts address food production to support food security in the context of city-region food systems, the complex nature of urban food systems has received less attention, particularly in secondary cities across the globe. Using household survey data collected in 2019 across 4 cities in Kenya and 14 cities in Zambia, we examined patterns of household food acquisition from key food retail locations. Households predominantly purchased food from open-air markets and vendors, and only a subset of households bought food from supermarkets. Variations in urban population size, area, and connectivity across the 18 cities presented a clustering of four city types that shape household food access and purchasing patterns at food retail locations. Despite a growing narrative that supermarkets and western diets will dominate SSA's urban food systems, our findings suggest that low- to middle-income households will continue to purchase food at open-air markets in SSA's secondary cities in the coming years. Attention to these urban household purchasing patterns can inform urban planning and governance priorities to ensure that SSA's food systems can meet urban food security needs.
