This volume examines how Nigeria, which was not long ago self-sufficient in food production, has become a net importer of food. It investigates the decline of the traditional farming systems in the three climatic zones of Nigeria and provides details of three development projects - one from each zone - and their effects on Nigerian agriculture. The text is designed for A level and first year undergraduate geography students. Examples of past A level examination questions are supplied and assignments aim to encourage students to use and understand the data provided in the text and tables.
