撒哈拉以南非洲（SSA）城市化和城市粮食不安全的趋势引发了围绕城市农业（UA）对城市生计的潜在好处的关键辩论。一些学者认为，普遍获得服务有助于城市家庭的食物数量、食物质量和收入需求。然而，许多引用的证据来自单一案例研究，特别关注大城市和高收入国家。因此，人们对普遍获得服务在非洲较小城镇家庭粮食安全中发挥的作用存在理解差距。这些较小的城市地区很可能在未来容纳撒南非洲城市人口的很大一部分，是决策者早期干预的重要场所。我们的分析基于从赞比亚和肯尼亚18个城市地区的2，687个低收入和中低收入家庭收集的调查数据，这些地区的人口不到20万。我们进行统计分析，调查UA和家庭粮食安全之间的关联，并评估哪些类型的家庭从事UA。我们发现，在我们的样本中，33%的家庭从事UA和UA和家庭粮食安全之间的关系有有限的统计意义。我们的研究结果揭示了三个关键的障碍，即结算手续，财产权，距离食品零售商。这些障碍意味着城市规划者和决策者需要重新审视如何就住宅开发、土地保有权、交通基础设施和城市空间利用等问题作出决定，因为这些问题影响到家庭生产、销售和获得粮食的能力。政策和规划机制应进一步认识到普遍获得服务在非洲城市粮食系统中的地位，传统市场、非正规贸易和现代食品零售也在其中发挥着不可或缺的作用。
Trends in urbanization and urban food insecurity in sub-Saharan Africa (SSA) have stimulated critical debates around the potential benefits of urban agriculture (UA) to urban livelihoods. Some scholars suggest that UA can contribute to the food quantity, food quality and income needs of urban households. However, much of the evidence cited comes from single case studies, with particular attention paid to large cities and high-income countries. There is a resulting gap in understanding regarding what role UA plays in the food security of households in smaller African cities and towns. These smaller urban areas are likely to house a large fraction of SSA's urban population in future and are important sites for early intervention by policymakers. Our analysis is based on survey data collected from 2,687 low- and low-middle income households in 18 urban areas with populations of less than 200,000 across Zambia and Kenya. We perform statistical analyses to investigate the association between UA and household food security and assess which types of households are engaged in UA. We found that 33% of households in our sample are engaged in UA and there was limited statistical significance in terms of the relationship between UA and household food security. Our results reveal three key barriers to UA, namely settlement formality, property rights, and distance from food retailers. These barriers imply the need for urban planners and policymakers to revisit how decisions are made about issues such as residential development, land tenure, transport infrastructure, and the use of space in cities, as these affect the ability of households to produce, sell, and access food. Policy and planning mechanisms should further recognize the embeddedness of UA within African urban food systems, in which traditional markets, informal trading, and modern food retail also play an integral role.
