Link between structural risk factors for adverse impacts of COVID-19 and food insecurity in developed and developing countries

COVID-19 has had serious consequences for world food security; lockdowns and social distancing have led to changes in global food value chains, primarily affecting the poorest of the planet. The aim of this research is to analyse the relationship between food insecurity and the structural risk factors for adverse impacts of COVID-19. To that end, 12 contingency tables are constructed to identify the association between the pillars of the food insecurity index and the INFORM COVID-19 Risk Index. We use the Gamma coefficient as a measure of association. In addition, this paper proposes a synthetic index produced by applying the TOPSIS method, using the pillars of the two aforementioned indices (criteria) to establish a ranking of 112 countries (alternatives) ordered from highest to lowest risk faced in the key year of the pandemic, 2020. The results show that the two problems are connected, indicating to international organizations that countries with worse food insecurity will suffer more serious consequences from extreme situations such as the one experienced during the pandemic. The ranking established directs international organizations' attention to countries such as Haiti, Zambia and Burundi, highlighting their greater need for an injection of financial aid than other emerging economies. Conversely, Switzerland is the country with the lowest combined risk.
