The book presents results of the Defragmenting African Resource Management (DARMA) Project covering the Lake Chilwa basin in Malawi. The central theme is that, in order to ensure resource base sustainability, research and management within the basin should adopt an ecosystems approach. Presently, research and management of the basin is sector-based, hence resource user conflicts are increasing. User demand for various resources is increasing rapidly, mainly due to population increase and lack of alternative economic activities, thereby presenting challenges to sustainable resource management. Specific areas of sectoral interconnections are highlighted and defragmentation options suggested. (Series: Defragmenting African Resource Management DARMA] - Vol. 1)
