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.
Aqueduct Global Maps 3.0 Data include indicators of water quantity, water variability, water quality, ESG risk, and access to water.
New data on WRI's Aqueduct platform ranks the world's countries from least to most water-stressed.
This data ranks countries and their subnational areas – like states and provinces – by several water risk indicators, including baseline water stress and drought risk.
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.
