Application of Environmental Flows in River Basin Management

11th -15th Feb 2008 - Iguacu, Brazil
IW:LEARN Regional Training Workshop for Latin America/Caribbean How can river basin management meet the needs of people and economic development alongside protection of the environment? This is the main challenge facing sustainable development in river basins today where dams or surface water abstraction have modified flows. Environmental flows are being applied in an expanding number of basins worldwide to meet this challenge. Environmental flows entails setting allocations of water between uses, whether for agriculture, hydropower, cities or sustaining wetlands and fisheries. Amounts allocated and the timing of flows are set using participatory processes, based on assessments of the social, economic and environmental impacts of alternate flow regimes. The World Conservation Union (IUCN) and GEF-IW:LEARN, in partnership with the World Bank Institute, are holding a training workshop.

Learning Objectives

1.Understanding the links between river flow regimes and economic,social and ecological impacts
2.Introduce methods for flow assessment and options for modifying flows
3.Review requirements for enabling implementation of environmentalflows
4.Synthesis of components into practical designs for application of environmental flows
Compose follow-up plans and decide how to use the Environmental Flows Network in the LAC Region
