Researchers and farmers have called on the government to revive agricultural extension departments in each state of the federation as part of measures to tackle various challenges retarding agricultural productivity and efforts to ensure food security. The COVID-19 pandemic has disrupted farming activities, supply chains and food inflation. The cost of food in Nigeria increased 17.21% in November 2021 over the same month in the previous year, and the yearly food inflation rate rose for the 24th consecutive month to 20.75%. Reviving agricultural extension services would help farmers boost productivity and more food in circulation, while understanding the problems of farmers and relaying them to researchers would help resolve the problems associated with food production. Nigeria is food-insecure due to production deficits and low farmers' productivity, leading to persistent food inflation. Reviving extension services is key to achieving food self-sufficiency and surplus for export.
