Good science is essential for good policy. 

The partnership between IISD’s Water Program and IISD-ELA brings together more than 40 years of rigorous aquatic science with 25 years of global policy analysis and practical guidance. Our combined expertise in hydrology, modelling, biology, limnology, ecosystem services and policy is directed at helping governments and industry to manage water and related resources in such diverse contexts as agriculture, hydro-electric operations and mining, to minimize effects on people and ecosystems.

With the best available science and collaborative analyses, our water solutions are evidence based, long term and meet the needs of a range of stakeholders.
