That’s because upstream forests, wetlands and other “natural infrastructure” play a critical role in supplying clean water downstream. They stabilize soil and reduce erosion, regulate water flow to mitigate floods and droughts, and purify water. Yet the world’s watersheds lost 6 percent of their tree cover on average from 2000-2014, putting citizens at risk of losing their water supplies.
Global Forest Watch (GFW) Water, a global mapping tool and database launched today, examines how forest loss, fires, unsustainable land use and other threats to natural infrastructure affect water security throughout the world. GFW Water provides data sets, statistics and risk scores for all of the world’s 230 watersheds, areas of land where all of the water drains to a common outlet such as a river. Users can drop a pin anywhere to learn about the risks to the water supply near them, and find resources on how investing in natural infrastructure protection can help alleviate these threats.
