Assessment of the Sustainability of Vegetable Production under Fadama in Northern Guinea Savannah Zone of Nigeria

Abstract

The assessment of the sustainability of vegetable production under Fadama based on the value of the Sustainability Index (Z0 = 422) imply that the system falls far short of the criteria for sustainability (Z0 or Z1 = 0), indicating that the present system of producing vegetables under Fadama is not sustainable. Optimizing the present system using Goal Programming, led to improvements in the sustainability of the system (Z1 = 146).The improvements occurred through a reduction in land use intensity.
