This map shows the average exposure of water users in each river basin to water stress, the ratio of total withdrawals to total renewable supply in a given area. A higher percentage means more water users are competing for limited supplies.
Nearly 450 million hectares of degraded forest landscapes — an area the size of the European Union — offer opportunities for restoration in Africa, more than in any other continent

Coral reefs are classified by estimated present threat from watershed-based pollution, which threatens more than 25 percent of reefs globally.
Coral reefs are classified by estimated present threat from marine-based pollution and damage, which threatens approximately 10 percent of reefs globally.
Coral reefs are classified by estimated present threat from coastal development, which threatens approximately 25 percent of reefs globally.
The map shows estimated aragonite saturation state (an indicator of ocean acidification) for CO2 stabilization levels of 380 ppm, 450 ppm, and 500 ppm, which correspond approximately to the years 200
The map reflects the locations of thermal stress (i.e., abnormally high sea surface temperatures) on coral reefs between 1998 and 2007 based on coral bleaching observations (in purple) and severe ther
The assessment of social and economic vulnerability of countries and territories to reef loss is based on exposure to reef threats, reef-dependence, and adaptive capacity.
