Why FreshWater Watch matters


As water experts, we’re engaging communities in vital research and water quality issues.


Fresh water ecosystems purify water and ingest waste. This ecosystem service is valued at US$400 billion worldwide annually.


As water quality declines in some regions, more than 50% of native freshwater fish species and nearly one third of the world’s amphibians are at risk of extinction.
