In many parts of the tropics, intensive, export-oriented monocropping has destroyed both local self-sufficiency and biologically rich and stable environments. The rehabilitation of these savanna regions - as yet relatively neglected by environmentalists - is vital for the success of any strategy for sustainable development. This study focuses on just such a district in Ghana and uncovers the complex factors responsible for environmental degradation. It suggests policies based on the regeneration of the local economy, diversification of agricultural products and markets, making use of local farmers' knowledge, and involving the community in drawing up environmental agendas.
