摘要

COVID-19 大流行开始后,全球粮食价格大幅上涨。本文探讨了大流行期间粮食价格上涨对布基纳法索粮食安全的影响。我们旨在回答两个主要问题。首先,粮食价格冲击如何影响家庭粮食不安全?第二,家庭采取了哪些应对策略来应对这些价格冲击?利用全国范围内的高频纵向数据,我们采用家庭固定效应模型来研究这些影响。在缺乏当地食品价格直接信息的情况下,我们使用家庭报告的价格冲击来捕捉省一级的价格上涨情况,并表明结果与国家一级的价格上涨情况一致。价格冲击对最贫困家庭的影响最为严重。此外,农村地区的粮食不安全程度比城市地区更高。农村地区较贫困家庭的比例较高是造成这种差异的部分原因。我们发现,家庭主要依靠布基纳法索和国外亲戚提供的更多援助来应对冲击。这项研究首次使用带有家庭固定效应的面板数据来研究大流行病期间粮食价格上涨对发展中国家粮食不安全的影响,并研究家庭采用的应对机制。鉴于全球粮食价格可能会长期居高不下,我们的研究结果对广大发展中国家具有借鉴意义。此外,鉴于对最贫困人口和生活在农村地区的人口的影响过大,研究结果突出表明,需要制定政策来减轻价格冲击的负面影响,并加强布基纳法索等国家的整体粮食安全。

Navigating food price shocks in a pandemic: Food insecurity and coping mechanisms in Burkina Faso

Global food prices rose substantially after the start of the COVID-19 pandemic. This paper examines the impact of rising food prices during the pandemic on food security in Burkina Faso. We aim to answer two primary questions. First, how do food price shocks affect household food insecurity? Second, what coping strategies do households adopt in response to these price shocks? Leveraging country-wide high-frequency longitudinal data, we employ household fixed effect models to examine the effects. In the absence of direct information on local food prices, we use household-reported price shocks to capture province-level price increases and show that the results are consistent with national-level price increases.

We find significant and immediate increases in food insecurity following the price shocks, and this effect persists for at least two months. The price shocks most acutely affected the poorest households. Furthermore, food insecurity increased more in rural areas than in urban areas. The higher proportion of poorer households in rural areas explains part of this difference. We find that households primarily cope with the shock by relying on increased assistance from relatives in Burkina Faso and abroad.

This study is the first to use panel data with household fixed effects to examine the repercussions of the rise in food prices during the pandemic on food insecurity in a developing country and to examine the coping mechanisms employed by households. Given that food prices are likely to remain high globally for an extended period, our findings carry implications for the broader developing world. Furthermore, given the disproportionate effect on the poorest and those living in rural areas, the findings highlight the need for policies to mitigate the negative impacts of the price shocks and enhance overall food security in countries like Burkina Faso.

期刊介绍: World Development is a multi-disciplinary monthly journal of development studies. It seeks to explore ways of improving standards of living, and the human condition generally, by examining potential solutions to problems such as: poverty, unemployment, malnutrition, disease, lack of shelter, environmental degradation, inadequate scientific and technological resources, trade and payments imbalances, international debt, gender and ethnic discrimination, militarism and civil conflict, and lack of popular participation in economic and political life. Contributions offer constructive ideas and analysis, and highlight the lessons to be learned from the experiences of different nations, societies, and economies.
