Threats to the World's coral reefs Threats to the World's coral reefs
Major observed threats to the world's coral reefs include tourism, poison fishing, overexploitation, sedimentation, coral harvesting, dynamite fishing and pollution. This graphic explains which activities or conditions are affecting various coral reefs throughout the world. The graphic 'Major Threats to Reefs' shows the percentage of reefs that are threatened by overexploitation, coastal development, inland pollution and marine pollution, and the...

Trends and forecasts in water use, by sector Trends and forecasts in water use, by sector
Throughout the 20th century, global water use has increased in the agricultural, domestic and industrial sectors. Evaporation from reservoirs has increased at a slower rate. Projections indicate that both global water use and evaporation will continue to increase. This graphic shows water consumption, withdrawal and waste, in cubic kilometres per year, for the agricultural, domestic and industrial sectors, and shows evaporation from reservoirs. T...

Shrinking of the Aral Sea: socio-economic impacts Shrinking of the Aral Sea: socio-economic impacts
Over the past 30 years, the Aral Sea in the former Soviet Union has shrunk to less than half of its original size. This graphic shows the Aral Sea as it was in 1960 and as it appeared in 2001. It shows that a former fishing zone is now a dry zone affected by salination. Areas that were previously food crops (partly irrigated) are now cotton and rice crops, widely irrigated. Other changes include the replacement of fish exports with fish imports, ...

Urban water supply and wastewater on a shallow aquifer Urban water supply and wastewater on a shallow aquifer
This graphic shows the changes in water supply and wastewater disposal that occur through four stages of growth of a settlement: early settlement; the town becomes a city; the city expands and the city expands further. The changes include increased groundwater pollution and changes in pluvial drainage, the water table and wellfields.

DPSIR framework for State of Environment Reporting DPSIR framework for State of Environment Reporting
The DPSIR framework (Driving Forces-Pressures-State-Impacts-Responses) is used to assess and manage environmental problems. Driving forces are the socio-economic and socio-cultural forces driving human activities, which increase or mitigate pressures on the environment. Pressures are the stresses that human activities place on the environment. State, or state of the environment, is the condition of the environment. Impacts are the effects of envi...

Major river basins of the world Major river basins of the world
Rivers form a hydrological mosaic, with an estimated 263 international river basins covering 45.3% of the land surface area of the earth, excluding Antarctica. This graphic shows the locations of 26 of the world's major river basins. A basin is defined as the land area (watershed) where all surface water drains to a certain river.

Total global saltwater and freshwater estimates Total global saltwater and freshwater estimates
Estimates of global water resources based on several different calculation methods have produced varied estimates. This graphic illustrates the proportions of saltwater and freshwater that make up the earth's water resources. It also shows what percentage of the world's freshwater is located in lakes and river storage; in groundwater, including soil moisture, swamp water and permafrost, and in glaciers and permanent snow cover.

Arctic, topography and bathymetry (topographic map) Arctic, topography and bathymetry (topographic map)
The Arctic is extremely diverse in terms of landscapes, varying from pack and drift ice to rugged shores, flat coastal plains, rolling hills and mountains surpassing 6000 metres above sea level (Denali, 6,194 m asl, in sub-arctic and boreal Alaska). The region has rivers and lakes, tundra and the largest forests in the world (the Russian Taiga).

World ocean bathymetric map World ocean bathymetric map
The continental shelves, ridges and sea mounts are the most productive areas in terms of biodiversity, and is of highest importance for economic activities. It is also here that natural resources extraction - such as oil and gas - takes place. The largest expanses of ocean are vast plains of depths between 1500-5000 meters. The deepest areas are the trenches where the continental plates meet, such as the Marian Trench of the Pacific.
