Promoting water demand management from local to regional level : proceedings of the exchange visit seminar for directors

The Pangani River Basin covers an area of about 43,650 km2, mostly in Tanzania with approximately 5% in Kenya. The Basin contains a wide array of resources of which water and arable land are arguably the most important to its 3.7 million Tanzanian inhabitants.
