Transformation of the Three Pillars of Agri-Food Sustainability around the COVID-19 Crisis-A Literature Review

The COVID-19 crisis has disrupted economies and societies and the sustainability characteristics of agri-food due to a significant decline in turnover, difficulties in transportation, and changes in market and contact habits. An analysis was carried out using the PRISMA protocol and the Scopus, Web of Science, and Science Direct electronic databases. The aim of this research is to present the main research issues in agri-food sustainability (economic, environmental, and social issues) in the pre-COVID-19 period, to compare it with the research trends in the COVID-19 period, and to explore the influence of the epidemic. This research looks for research gaps and possible future research directions. Research before COVID-19 was primarily concerned with environmental and economic sustainability. The main focus areas were business development and environmental issues. During COVID-19, the focus shifted to economic sustainability. Survival was the primary issue. The main research areas were financial, inventory, waste management, and innovation issues. Food safety and digitalisation were highlighted. Precision agriculture, short food supply chains, and collaboration increased efficiency. The role of trust has increased. The COVID-19 experience is valuable for almost all disciplines. Policy, health, and economic decision-makers can apply better solutions to future crises.
