Abstract

The study sought to ascertain the changes in the food insecurity status of households during the COVID-19 pandemic. The study made use of secondary data obtained from the 5 Waves of the National Income Dynamics Study-Coronavirus Rapid Mobile Survey (NIDS-CRAM). Descriptive statistics, food insecurity index and independent sample -test were used to compare the mean differences in the food insecurity statuses of the households over the 5 Waves. The study found that there was an increase in food insecurity as the COVID-19 progressed from Wave 1 to 5. Significant differences at the 1% level were observed between Wave 5 and Wave 1 as well as between Wave 5 and Wave 3. The study concludes that there was food security in the initial progression of the COVID-19 pandemic which deteriorated. The study recommends a reconsideration of the scrapping of the top ups on the social grants. This will likely tighten the dire economic situation the households find themselves in. There is need to expand the social safety nets to accommodate the vulnerable in society. Short and localised value chains should be promoted to improve food accessibility during times of crisis.

摘要

该研究旨在确定新冠疫情期间家庭粮食不安全状况的变化。该研究利用了从国民收入动态研究-冠状病毒快速移动调查(NIDS-CRAM)的5轮调查中获得的二手数据。描述性统计、粮食不安全指数和独立样本检验被用于比较5轮调查中家庭粮食不安全状况的平均差异。研究发现,随着新冠疫情从第1波发展到第5波,粮食不安全状况有所增加。在第5波和第1波之间以及第5波和第3波之间观察到了1%水平的显著差异。该研究得出结论,在新冠疫情初期存在粮食安全,但后来情况恶化。该研究建议重新考虑取消社会补助金的追加款项。这可能会加剧家庭所处的严峻经济形势。有必要扩大社会安全网,以容纳社会中的弱势群体。应推广短而本地化的价值链,以在危机时期改善粮食可及性。
