Water for Nature and People

Find out how the Conservancy determines optimum river flows for nature and people.

Nearly 2,000 users worldwide have used the Indicators of Hydrological Alteration (IHA) software to assess how rivers, lakes and underground basins have been affected by human activities over time or to evaluate future water management scenerios.

While the IHA software is available free of charge for users to download, The Nature Conservancy has recently designed an online training course to assist users with this ever-evolving technology. Below are links to help launch the training.
