Linkage Effects of Agriculture Expenditure on Food Security in Nigeria

Abstract

This study examined the linkage effect of agriculture expenditure on food security in Nigeria. Pertinent time series data ranging from  1981 to 2022 were adopted for the research analysis. For testing the existence or lack of a unit root in the series and an endogeneity issue  in the model, we employed the Phillip Perron and simultaneity tests. In assessing the nature of relationship among agriculture expenditure, climate change, security index, population growth rate, agricultural mechanization and food security; two stage least  squares approach was employed. The study found that Nigeria's food security is significantly impacted by agriculture expenditure,  climate change, and security index. During this study period, agricultural mechanization had a considerable detrimental influence on food security. However, population expansion showed a negligible improvement in food security. We conclude by urging an increase in  agricultural spending in line with the 2003 Maputo Declaration's recommendations. Once more, Nigerian farmers should be pushed to  embrace climate smart farming practices by publicizing them.
