Abstract

Purpose

This study aims to assess the effects of natural disasters on food security in a sample of 40 sub-Saharan African countries. First, the authors assess the effects of natural disasters on the four dimensions of food security and second, the authors disaggregate natural disaster using the two dimensions that are most representative, namely, hydrological and biological disasters.

Design/methodology/approach

The regressions are based on the generalised method of moments on a data set covering the period 2005–2020. Natural disasters are measured by the total number of people affected and food security by its characteristics: access, availability, use and sustainability.

Findings

The results show that natural disasters increase the prevalence of undernourishment but reduce dependence on cereal imports. An increase in natural disasters by 1% increases the prevalence of undernourishment by the same proportion. As for import dependency, a 1% increase in natural disasters reduces dependency by 2.2%. The disaggregated effects show that hydrological disasters are more significant than biological disasters in impacting food security. Floods reduce the average energy supply adequacy but also dependence on cereal imports. Policy implications are discussed.

Originality/value

The study complements the extant literature by assessing the effects of natural disasters on food security in a region where food insecurity is one of the worst in the world.

自然灾害对撒哈拉以南非洲粮食安全的影响
目的 本研究旨在以撒哈拉以南非洲 40 个国家为样本,评估自然灾害对粮食安全的影响。首先,作者评估了自然灾害对粮食安全四个方面的影响;其次,作者利用最具代表性的两个方面,即水文灾害和生物灾害,对自然灾害进行了分类。结果结果表明,自然灾害增加了营养不良的发生率,但减少了对谷物进口的依赖。自然灾害每增加 1%,营养不良的发生率就会增加相同的比例。至于进口依赖度,自然灾害每增加 1%,依赖度就会降低 2.2%。分类效应表明,水文灾害比生物灾害对粮食安全的影响更大。洪水降低了平均能源供应充足率,但也降低了对谷物进口的依赖。本研究通过评估自然灾害对粮食安全的影响,对现有文献进行了补充。
