What we do

This is a watershed moment. Rivers, lakes, aquifers, wetlands, coasts, oceans and the wildlife they support are under threat from climate change, pollution and misuse. Drought, flood and sea-level rise makes swathes of land uninhabitable or unproductive. Two-thirds of the global population live in water-stressed areas. Water scarcity leads to conflict. Dirty water leads to dead zones and disease. And yet media coverage of these issues is light when compared with others.

That’s where WATERSHED comes in. Our independent, not-for-profit, investigative journalism shines a light on the water crisis in its many forms, using in-depth, rigorous, evidence-based stories hold the powerful to account, uncover abuses, tell overlooked stories, and champion solutions.
