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.

Latin American Leader Roberto Artavia Elected to WRI Board

The World Resources Institute (WRI) has elected Roberto Artavia to its board of directors. Artavia is a distinguished leader in business education, conservation of marine resources, and sustainable development in Latin America.

Ironically, Flood Control is Flooding New Orleans

Man-made flood-control systems—such as levees, upstream dams, and canals—continue to be responsible for widespread damage to the New Orleans and Louisiana landscapes.

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.

The Caribbean region, as defined by this analysis, encompasses 35 countries and territories bordering the Gulf of Mexico and Caribbean sea, including the oceanic island of Bermuda.

Threats to reefs from coastal development were estimated based on distance from cities, ports, airports, and dive tourism centers, as well as population density, population growth, and tourism growth

Agriculture, though important to economic development and food security, is a source of increased sediment, nutrient, and pesticide runoff. This map shows agricultural lands by slope category.

Threats to reefs from sedimentation and pollution from inland sources were modeled for over 3,000 watersheds discharging into the Caribbean.

Improving coastal resource management and coral reef protection by providing comprehensive information on land-based sources of threat to coral reefs.

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.

Immigration Linked to Degraded Ecosystem

Border security is not typically recognized as being tied to environmental changes, but in this recent article by The New York Times, the links are clear. It details how declining fish catches in northwest Africa are fueling immigration to Europe.

Choking Coastal Waters

My team at WRI, together with Dr. Bob Diaz at the Virginia Marine Institute, has identified and mapped 415 eutrophic and hypoxic coastal systems worldwide through an extensive literature review. Of these, 169 are documented hypoxic areas, 233 are areas of concern and 13 are systems in recovery.

Pioneering efforts to quantify the risks posed to reefs and the value they provide to people and nature.
