Notes

Abstract:
Tanzania’s National Water Policy of 2002 and Water Resources Management Act of 2009 establish an order of priority in decision-making as related to allocation of surface water resources. According to these frameworks, basic human needs for water use are afforded first priority, and then water for the long-term sustainability of ecosystems is given second priority in decision-making about water. Implementation of this legislation means that water managers in Tanzania must understand the needs of ecosystems in terms of quantity, quality and timing of freshwater flows. Environmental flow assessment (EFA) is a process by which these ecosystem needs are identified and quantified to the best degree possible. More than 200 approaches have been employed worldwide for EFA, but the general consensus to which many people are arriving is that EFA should be a holistic process that considers the flow needs of ecosystems and the flow linkages to the availability and quality of freshwater ecosystem services upon which humans depend. Further, ideally EFA should be conducted with input from scientists, water managers, and those with a stake in resource management decisions.
