摘要

COVID-19 大流行影响了撒哈拉以南非洲的农户。以加纳为例,我们研究了农户在 COVID-19 冲击下对粮食和营养不安全的抵御能力。我们首先与农户户主进行了焦点小组讨论,以确定农户的抗灾能力来源和 COVID-19 的不同冲击。然后采用多阶段随机抽样技术对 252 户农户进行了调查。我们采用了不同的计量经济学建模技术,即多指标多原因建模程序、普通最小二乘法和多项式概率模型进行数据分析。我们的研究结果提供了支持性证据,证实 COVID-19 的冲击削弱了农户的抗灾能力以及粮食和营养安全。与农村家庭和女户主家庭相比,城市家庭和男户主家庭的粮食和营养不安全程度更高。农户的适应能力极大地促进了农户的抗灾能力以及粮食和营养安全。研究结果表明,从当前大流行病中吸取的经验教训可帮助政策制定者、政府和国际组织制定适当的应对措施和干预措施,以加强和支持农户对粮食和营养安全以及系统性冲击(如加纳的 COVID-19)的复原力。

Food and Nutrition Insecurity and Farming Household Resilience to COVID-19 Shocks in Ghana
The COVID-19 pandemic affected farming households in Sub-Saharan Africa. As a case in point, we examine farming households’ resilience to food and nutrition insecurity in Ghana under the COVID-19 shocks. Focus group discussions were initially conducted with farming household heads to identify households’ sources of resilience and the different COVID-19 shocks. A multi-stage random sampling technique was then used to survey 252 farming households. We used different econometric modelling techniques, that is, the multiple indicators multiple causes modelling procedure, ordinary least square, and multinomial probit model, for data analysis. Our results provide supportive evidence affirming that COVID-19 shocks undermine farming households’ resilience and food and nutrition security. Urban and male-headed households experience more food and nutrition insecurity than rural and female-headed households. Farming households’ adaptive capacity significantly contributed to household resilience and food and nutrition security. The findings suggest that lessons learned from the current pandemic can help policymakers, governments, and international organisations build adequate responses and interventions that strengthen and support farming households’ resilience to food and nutrition security and systemic shocks such as COVID-19 in Ghana.
