Review on market re-orientation of extension services for value chain development in Borno State, Nigeria

Hitherto the primary focus of agricultural extension in Borno State has been to ensure increasing agricultural production for food security. However, the current emphasis is on enhancing rural incomes through market re-orientation. This change was necessitated by the realization that subsistence food production can no longer provide for a decent living and therefore increased engagement in commercial food production and...
