This policy note provides an overview of the range of actions,
policies, and institutions around the globe that address nutrient
pollution and eutrophication.
The World Resources Institute (WRI) and the U.S. Environmental Protection Agency (EPA) today announced a collaboration to deliver improved science and practical tools to help companies and governments protect ecosystems and address climate change.
This map identifies 168 eutrophic and hypoxic coastal areas in Europe. Fifty-nine of these are documented hypoxic areas, 106 are areas of concern, and 3 are improved systems that are in recovery.
This map identifies 25 eutrophic and hypoxic zones, with 3 having documented hypoxia and 22 areas of concern. Most are found in Brazil, Chile, and Peru.
This map identifies 131 eutrophic and hypoxic coast zones in North America and the Caribbean. Sixty-two have documented hypoxia, 59 are areas of concern, and 10 are systems in recovery.
Eutrophication—the overenrichment
of water by nutrients such as nitrogen and
phosphorus—has emerged as a leading water
quality problem. This report identifies over 415 areas
worldwide that are experiencing eutrophication symptoms, and there are significant information gaps in many regions.
This project’s goal is to reverse the impacts of aquatic eutrophication by assessing its global extent, identifying its causes, and providing policy strategies and solutions.
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.
