ABSTRACT
Food security is an essential element of household well-being in a sustainable livelihood. This paper seeks to provide support for investing in smallholder agriculture to achieve food and nutrition security among food insecure households in Nigeria. The paper points to the importance of smallholder agricultural production and development policies in combating vulnerability to food insecurity. It uses literatures from various sources to explore the extent of vulnerability to food and nutrition insecurity, its underlying causes, existing constraints and opportunities to improve households’ welfare and food security status. The overriding aim is to reduce hunger and poverty for millions of farming families by increasing agricultural productivity in a sustainable way.
