The Coronavirus Disease 2019 (COVID-19) epidemic and climate change are rapidly influencing the global economy, including food security. Food security is now evidently intertwined with both challenges. However, research on the impact of these two factors on food security is still lacking. Therefore, this study reviews the literature, specifically focusing on the effects of climate change and COVID-19 on global food security. The current study incorporates various research designs and a PRISMA-based Review (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). This review examined five peer-reviewed papers from 2020 to 2021, focusing on the impact of climate change and COVID-19 on global food security. The Science of the Total Environment published the most papers, followed by NPJ Science of Food, Environmental Resource Economics, and Reviews in Fisheries Science Aquaculture. The majority of papers were in the field of environmental sciences and ecology. However, the research has limitations. For example, only WOS (Web of Science) was used as the core source. “PubMed, Google Scholar, and grey literature were excluded from the list of scholarly databases, with only Web of Science (including Science Citation Index Expanded, Social Sciences Citation Index, and Arts Humanities Citation Index) and Scopus deemed scholarly. Another restriction was the inclusion of only articles in English. The study concluded that the impact of COVID-19 and climate change on global food security fell under the umbrella of environmental ecology. A comprehensive literature review may examine and explain current trends and accessible research articles for future mitigation measures.
