Aral Sea problem
The Aral sea is Uzbekistan's biggest lake, it used to be the fourth biggest lake in the world. But nowadays the problem of the Aral Sea is disturbing the people of the world, because the level of water in the Sea is decreasing.
Over the last 30 years, the level of the Aral Sea has dropped by approximately 1516 meters and the shoreline has moved away by dozens of kilometers. The amount of water brought to the Aral Sea by the Amudarya and Syrdarya is diminishing every year. Currently, it is eight and three cubic kilometers respectively, whilst 30 years ago the Amudarya alone brought 50 km3. The water table of the Aral Sea has been reduced almost 5 times since then. The streams of warm and humid air, originating above the Aral Sea, used to make a natural barrier for the air coming in from Russia and Kazakhstan. This barrier has been destroyed and the cold air now rushes towards Central Asia. It can suddenly bring hail and showers, sometimes even at the height of summer, causing much damage, reducing the growing period of heat-loving crops and bringing about a great deal of complications. The worsening of ecological situation in the Aral Sea zone adversely affects the health of residents and the level of reproduction.
The tragedy of Aral Sea disappearance is one of the most convincing and vivid cases against unbalanced activities undertaken by the human society neglecting sustainable development, which are so numerous in the creative and simultaneously destructive latter half of the 20th century. During this period the humanity not only had the unprecedented achievements in engineering development, but also damaged the nature more than ever. Such a predatory outrage upon the planet was caused by the impetuous technological revolution, which at that time had been declared as a watershed of the human history, until the most advanced people found that very grave environmental consequences were hidden behind its frontage.
Almost all current global climatic, hydrological, and geological cataclysms (not only in the former socialistic countries) - the green-house effect, losses of rivers, lakes and wetlands, wide-spread desertification are caused by ambitious aspiration of people as if to provide their well-being, but in fact mainly for increasing property, domination and power, and followed by disregard of the fact that everything in the world is interdependent and has its own consequences in the form of large scale disturbance or transformations of natural processes. Some countries in the West recognized the necessity "to be respectful to the nature and to repay their debts to it" as early as the 1970s and 1980s, and in that time the community in the USSR just began thinking about ecological problems and has seen things clearly only when being on the verge of its collapse.
Drying up the Aral Sea that was a large water body with good quality water has reached such an extent that widespread nature degradation inside the dried area (at elevations less than 53 m + BSL) and outside its boundaries has resulted in the situation when this region is the natural disaster zone. The sea, which was the habitat of abundant flora and fauna and a natural regulator of climate in the adjacent irrigated area, degrades to such an extent that the desertification zone located between deserts Kyzylkum, Karakum and Usturt is formed. Vast areas of solonchaks and strongly saline lands, being sources of salt and dust transfer due to wind erosion, have occurred here.
In the coastal zone (above the elevation of 53 m + BSL) the ecosystem of the delta and a coastal zone, which was formed during many centuries was completely damaged; the lakes dried up, salinity of water increased; solonchaks appeared at the sites of the dried marshes; catch of fish and furry animal significantly diminished; migratory birds disappeared; flora and fauna degrade; and the local climate undergoes a change.
The five independent states located in the Aral Sea basin Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan have properly evaluated the necessity of tackling the problem of the Aral Sea and Prearalie (a dried coastal zone). The Heads of these states approved the Concept, in which the proposal to establish a new sustainable anthropogenic-natural complex in the South Prearalie in order to rehabilitate the productivity of this territory as much as possible was formulated.
The existing ecological situation is of great concern for all peoples living both inside and outside the Aral Sea basin. As a result, there have appeared many plans and proposals in order to solve, to a greater or lesser extent, the following issues:
protecting the population from adverse impacts of desertification;
restoring fauna and flora diversity to a maximally possible extent;
creating workplaces for the local population by means of rehabilitation of fishery, muskrat breeding, cattle breeding, processing sectors, etc.;
creating appropriate social and economic conditions necessary for improving the local standard of living by means of introducing high-yielding technologies in the field of water and land resources use;
preventing further degradation of the environment, and rehabilitation the environmental balance in the South Prearalie.
 Formerly, these issues had been addressed in two interrelated sustainable ecological zones (the Aral Sea and Prearalie) based on a certain hydrological regime of the Amu Darya and Syr Darya rivers. Social-economic activity in the vicinity of the sea and in deltas had been tightly related to the water regime of these zones and their peculiarities and not intervened significantly in natural conditions. At present, it is necessary to rehabilitate the former situation as much as possible and to direct developing negative trends conversely. Numerous donors tried to assist the disaster epicenter, but they were not based on the integrated approach. Real actions were undertaken under support of the International Fund for the Aral Sea (IFAS) and the GEF, which initiated the projects for rehabilitating wetlands (the Sudoche Lake Rehabilitation Project) and some water bodies.
Many concerns about the future of the Aral Sea were expressed in the speech given by the head of the Republic at a jubilee session of the General Assembly (October 1995) in New York on the occasion of the 50lh anniversary of the United Nations. Again, the President drew the attention of the international community to the problem of the Aral Sea.
