摘要
本文旨在研究 2000-2020 年间城市化和国内冲突对 43 个非洲国家粮食不安全严重程度的影响。随后,采用异质选择模型方法进行了估算。结果显示,城市化和国内冲突加剧了粮食不安全。平行线概率假设的结果特别表明,城市增长率每增加一个单位,属于高风险粮食不安全类别的概率就会增加 0.6 倍以上。此外,结果表明,城市化对粮食不安全的影响受到非洲内部冲突的调节,净效应为 0.692。当净正效应被抵消时,这相当于 2.315 的政策阈值。因此,本研究强烈建议非洲经济体在控制城市化步伐的同时发展城市农业,以减少粮食不安全,避免可能发生的内战。2023."实现加纳的粮食安全:治理重要吗?Politics & Policy 51(4):https://doi.org/10.1111/polp.12540.Ayanoore, Ishmael, and Sam Hickey.2022."非洲自然资源治理政治的重构:加纳本地内容立法进程的启示》。Politics & Policy 50(1):https://doi.org/10.1111/polp.12449.Oehmke, James F., Sera L.

Urbanization, civil conflict, and the severity of food insecurity in Africa
The objective of this article is to examine the impact of urbanization and civil conflicts on the severity of food insecurity for a panel of 43 African countries over the period 2000–2020. Subsequently, the heterogeneous choice models approach was used for the estimations. The results show that urbanization and civil conflict increase food insecurity. The parallel line probability hypothesis results specifically show that a one-unit increase in urban growth rate increases the probability of belonging to a high-risk food insecurity category by more than .6 times. Furthermore, the results show that the impacts of urbanization on food insecurity are modulated by civil conflicts in Africa leading to the net effect of .692. This corresponds to the policy threshold of 2.315 when the net positive effect is canceled out. Therefore, this study strongly recommends the need for African economies to develop urban agriculture while controlling the pace of urbanization in order to reduce food insecurity and avoid possible civil wars.
