Persistent land degradation in the form of soil erosion, nutrient depletion, soil organic matter depletion and soil productivity decline as well as variability in rainfall and temperature could negatively impact food security in most African countries. These concerns are particularly relevant in South-eastern Nigeria where land is intensively cultivated by local farmers. This calls for a different approach in the management of soil, land and water in order to improve soil productivity so as to achieve food security and reduce poverty in the country.This policy brief examines how agricultural intensity and climate change will impact crop yields across the three agro-ecological zones (AEZs) in Southern Nigeria.
