Содержание слайда: Emergence and development of the ecological tragedy of Aral In the early 1960s,[10] the Soviet government decided the two rivers that fed the Aral Sea, the Amu Darya in the south and the Syr Darya in the northeast, would be diverted to irrigate the desert, in an attempt to grow rice, melons, cereals, and cotton. This was part of the Soviet plan for cotton, or "white gold", to become a major export. This eventually succeeded, and today Uzbekistan is one of the world's largest exporters of cotton.[11] The construction of irrigation canals began on a large scale in the 1940s. Many of the canals were poorly built, allowing water to leak or evaporate. From the Qaraqum Canal, the largest in Central Asia, perhaps 30 to 75% of the water went to waste. Today, only 12% of Uzbekistan's irrigation canal length is waterproofed.

Содержание слайда: Possible environmental solutions Many different solutions to the different problems have been suggested over the years, varying in feasibility and cost, including: Improving the quality of irrigation canals Installing desalination plants Charging farmers to use the water from the rivers Using alternative cotton species that require less water Using fewer chemicals on the cotton Moving farming away from cotton Installing dams to fill the Aral Sea

Содержание слайда: Semipalatinsk test polygon – zone of ecological tragedy The Semipalatinsk Test Site (STS or Semipalatinsk-21) was the primary testing venue for the Soviet Union's nuclear weapons. It is located on the steppe in northeast Kazakhstan (then the Kazakh SSR), south of the valley of the Irtysh River. The scientific buildings for the test site were located around 150 km west of the town of Semipalatinsk (later renamed Semey), near the border of East Kazakhstan Province and Pavlodar Province with most of the nuclear tests taking place at various sites further to the west and south, some as far as into Karagandy Province. The Soviet Union conducted 456 nuclear tests at Semipalatinsk from 1949 until 1989 with little regard for their effect on the local people or environment. The full impact of radiation exposure was hidden for many years by Soviet authorities and has only come to light since the test site closed in 1991.

Содержание слайда: Economic solution of public health care, victim of nuclear tests Based on information collected during the missions and subsequent research, there is sufficient evidence to indicate that most of the area has little or no residual radioactivity directly attributed to nuclear tests in Kazakhstan. There are a few areas that have elevated residual radioactivity levels within the test site where the surface tests were performed and where a few underground tests vented to the atmosphere. Preliminary surveys of these areas indicated that the contamination is relatively localized.
