Abstract: Health guidelines to manage the COVID-19 pandemic could have led to unintended changes in states and processes that affect food systems, food security, and nutrition. The study conducted in Elgeyo Marakwet County, Kenya focused on the impacts of the pandemic on food security and post-harvest losses. A cross-sectional survey was used to gather information on food security concerns from household heads in Keiyo South. Questionnaires were administered to 400 household heads derived from 99,861 households.
