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.

Kazakhstan, topographic map Kazakhstan, topographic map
Kazakhstan is located in Central Asia, northwest of China; a small portion west of the Ural River in eastern-most Europe, comprising of 2,717,300 sq km. It has a population of 15,185,844 (2005). Major environmental concerns are: radioactive or toxic chemical sites associated with former defense industries and test ranges scattered throughout the country pose health risks for humans and animals; industrial pollution is severe in some cities; becau...

The Caspian Sea drainage basin The Caspian Sea drainage basin
The Caspian Sea runs north and south, extending over 1,200 km, with an average width of 320 km. It covers approximately 400,000 sq km (an area slightly larger than Germany). The population of the region is about 14 million, distributed over the coastal provinces of five countries: 6.5 million in Iran, 3.9 million in Russia, 2.2 million in Azerbaijan, 0.8 million in Kazakhstan and 0.4 million in Turkmenistan.

Water towers of Asia - glaciers, water and population in the greater Himalayas-Hindu Kush-Tien Shan-Tibet region Water towers of Asia - glaciers, water and population in the greater Himalayas-Hindu Kush-Tien Shan-Tibet region
The Himalayas–Hindu Kush, Kunlun Shan, Pamir and Tien Shan mountain ranges function as water towers, providing water to people through much of Asia. The glacier-fed rivers originating from the Himalaya mountain ranges surrounding the Tibetan Plateau comprise the largest river run-off from any single location in the world. While the mountains are homes to some 170 million people, the rivers that drain these mountains influence the lives of about 4...

Trends in the ice-breaking date in the Tornio river, Finland Trends in the ice-breaking date in the Tornio river, Finland
The icebreaking date for the Tornio River in Finland has been recorded since 1693. With the increased greenhouse effect, impacts on the cryosphere are likely. One impact will be less ice on rivers and lakes. Freeze-up dates will be delayed, and break-up will begin earlier. The period of river-ice could be shortened by up to a month. Many rivers within the temperate regions could become ice-free or develop only intermittent or partial ice coverage...

Regulation in the Volga river, 1934 compared to 1999 Regulation in the Volga river, 1934 compared to 1999
The construction of a large number of dams and industrial facilities on the rivers feeding the Caspian has caused a significant change in the quantity of water inflow. The creation of a succession of large reservoirs, especially on the lower and middle Volga, has led to significant losses in flow rate due to additional evaporation from the surface of the water.

Drought in Central and Southwest Asia Drought in Central and Southwest Asia
Turkmenistan and Iran have become drier. Dust storms pick up large amounts of salt and dust as they pass over the Kara-Kum desert and the Caspian Seashore, depositing it in the Volga River valley where it impairs the fertility of arable land.

Caviar imports to Japan, European Union and United States Caviar imports to Japan, European Union and United States
The Caspian area is the world’s main producer of wild caviar (83% in 2003) and supplies the three largest markets, the European Union, Japan and the USA. The construction of several hydroelectric power plants and dams along the Volga river significantly altered the flow of water into the delta and destroyed about 90% of the sturgeon’s spawning grounds, which can be as far as several hundreds of kilometres upstream. This graphic displays the repor...
