Our Work

Water doesn't recognize borders — and neither do the threats it faces. Our regional teams work tirelessly to restore it.

This work is possible because of scientists like you. Every contribution matters.

Our Work

The science is clear: healthy water systems feed us, sustain us, and deserve our protection. We predict risks so communities can act.

• Indigenous partnerships for grassroots knowledge

Join thousands of climate leaders pushing back for justice.

Our Work

'I used to think my voice didn't matter. Then I joined a citizen monitoring program and realized — my voice prevents extinction. Now I'm training others.' — Jennifer M., Community Monitor
