New Flows Assessment for the Pangani Basin, Tanzania

09 July 2010 | News story

The Pangani River Basin Management Project (PRBMP), implemented by the Pangani Basin Water Board, IUCN’s Water and Nature Initiative (WANI), the Dutch Development Organization (SNV), and local NGO PAMOJA, has recently developed a new Integrated Flow Assessment.

This assessment will aid the development and understanding of the river basin’s hydrology, environmental flows, and the links between the ecosystem and socio-economic resources of the watershed. A series of reports has provided information into the flow assessment and is now available online: click here.

Building on this information, stakeholders are now gaining a better understanding of social, economic and environmental trade-offs for different water allocations through the development of a number of scenarios”, said Katharine Cross, IUCN East and Southern Africa Water Programme Officer. She added that “the Pangani flow assessment allows water managers to make informed decisions about water allocations to many different sectors, such as agriculture, hydropower, and water utilities.”

The Pangani River Basin covers an area of 43,650 km², with a small portion in Kenya and the majority of the basin distributed across different administrative regions in Tanzania. The Pangani River rises as a series of small streams on Africa’s highest peak, Mt. Kilimanjaro, then passes through the arid Masai Steppe before reaching the estuary and Indian Ocean at the coastal town of Pangani.


The project generated technical information and developed participatory forums to strengthen the Integrated Water Resources Management in the Pangani Basin. This included the mainstreaming of climate change to support equitable provision and wise governance of the basin’s freshwater resources for livelihoods and nature for current and future generations.


The Project is based on Tanzania’s National Water Policy (2002) and the Water Resource Management Act (2009) which promotes integrated water resource management principles. The policy and legislation recommend that water be managed at the basin level in a participatory and equitable way, emphasizing the water sources’ sustainability and conservation.
