This map identifies 415 eutrophic and hypoxic coastal systems worldwide. Of these, 169 are documented hypoxic areas, 233 are areas of concern and 13 are systems in recovery.
Green infrastructure like forests, wetlands and coral reefs can help traditional “gray infrastructure” perform better. Yet, green-gray infrastructure projects remain relatively niche, mainly because of persistent myths about their costs and feasibility.
More than 700 coastal areas are affected by algal growth and dead zones, despite a growing number of global agreements to reduce water pollution.
Water quality trading can spur more cost-effective reductions of pollution. But they're most effective when they have a strong driver, like a cap, and the new memo isn't as instructive as it could be on that front.
For the cash-strapped government of Rio de Janeiro, restoring forests around the city is a smart investment. New research shows that forests can provide Rio with better water quality at lower cost.
Wetlands, forests and other green spaces are the original water infrastructure. For the first time, they can now be financed through bonds – just like other built infrastructure such as treatment plants and dams.
From clean water provision to storm protection, forests provide benefits for everyone—even those who live in the concrete jungle.
Forest restoration needn't be regarded as competition for scarce water resources. As a new report reveals, it can have a positive effect on water supply, among other benefits.
How to Achieve Measurably Cleaner Water Through U.S. Farm Conservation Watershed Projects
This joint report from WRI and the American Farmland Trust features lessons learned from six water quality targeting project success stories and highlights key factors that allowed these programs to achieve desirable environmental outcomes. It concludes with recommendations for both public and...
