This study assesses the extent of COVID-19-related food insecurity in Kenya, Tanzania, and Namibia. Using the Household Food Insecurity Access Scale, we measure food insecurity in various dimensions and document several food access disruptions associated with the COVID-19 pandemic between April and July 2020. Furthermore, we assess the association of COVID-19 countermeasures with the adoption of various strategies in line with the coping strategies index. We rely on a unique phone survey that followed households who participated in an earlier field-based survey. First, through Ordinary Least-Squares and Probit regressions, we show a strong and statistically significant association between COVID-19 countermeasures and food access disruptions and food insecurity in each of the three countries. We then use a multivariate probit regression model to understand the use of the various coping strategies, including reducing food intake, increasing food search, and relying more on less nutritious foods. We provide evidence on the complementarities and trade-offs in using these coping strategies. COVID-19 and related lockdown measures coincided with a deleterious increase in food insecurity in rural Africa.
本研究评估了肯尼亚、坦桑尼亚和纳米比亚与新冠疫情相关的粮食不安全程度。我们使用家庭粮食不安全获取量表，从多个维度衡量粮食不安全状况，并记录了2020年4月至7月间与新冠疫情相关的几次粮食获取中断情况。此外，我们根据应对策略指数，评估了新冠疫情应对措施与各种策略采用情况之间的关联。我们依靠一项独特的电话调查，该调查跟踪了参与早期实地调查的家庭。首先，通过普通最小二乘法和概率单位回归，我们发现新冠疫情应对措施与这三个国家中每个国家的粮食获取中断和粮食不安全之间存在强烈且具有统计学意义的关联。然后，我们使用多元概率单位回归模型来了解各种应对策略的使用情况，包括减少食物摄入量、增加食物搜寻以及更多地依赖营养较少的食物。我们提供了关于使用这些应对策略时的互补性和权衡取舍的证据。新冠疫情及相关封锁措施与非洲农村地区粮食不安全状况的有害加剧同时出现。
