Тәжікстандағы экологиялық мәселелер мен су тапшылығы

Environmental issues in Tajikistan include concentrations of agricultural chemicals and salts in the soil and groundwater, and soil erosion. Air pollution is a particular problem during times of the year when atmospheric conditions hold industrial and vehicle emissions close to the surface in urban areas. In summer, dust and sand from the deserts of Uzbekistan and Turkmenistan cause air pollution across the entire southwestern lowland region. Although a destructive civil war, budget shortfalls, poverty, and the dissolution of the Soviet Union reduced industrial and agricultural activity, these issues, as well as the destruction of infrastructure and loss of Soviet programs (such as the Committee on Nature Protection, state owned agriculture, and region wide networks of hydro posts) have amplified environmental concerns. Additionally, the Tajik government is hesitant to acknowledge these concerns, which has tensed its regional relationships. Water shortage first became a threat in Tajikistan under the Soviet Union's pressure to expand cotton cultivation in Central Asia. During this time, minimal regulation on water use was implemented and much of it was allocated towards irrigation. The Tajik government has since expanded limits on water use, however the agencies involved in their application lack the effective judicial and legal systems necessary to implement them. Agriculture accounts for 90% of Tajikistan's water use, and 33% of Tajikistan's irrigated land is used to cultivate cotton. Most polluted rivers in Tajikistan cross into several other Central Asian nations and are therefore a transnational problem; the Navruz experiment in 2000, which involved several Central Asian governments, discovered high levels of metals and radionuclides in the Aral Sea river basin. Uzbekistan has since insisted on operating under a 1994 agreement that required the neighbors to manage transnational environmental problems together, however Tajikistan maintains that its industry has had no impact on the environment and that the operation of its industrial sector is an exercise of sovereignty. All heavy metals in water are known to cause health problems when consumed, particularly arsenic, which causes liver damage, dermal lesions, and anemia,

From 1945 to 1965, the development of the USSR Nuclear Program resulted in the opening of the Andrasman, Chkalovsk, Digmai, and Taboshar uranium mines. Comparatively minimal cleanup efforts by Soviet and Tajik governments since the abandonment of the mines, in conjunction with Tajikistan's steep mountain topography, have caused uranium tailings to be carried by landslides into soil, pastures and public water sources. Studies in Taboshar and Digmai pit lakes and surrounding areas showed Uranium concentrations to be significantly higher than international recommendations in drinking water and local fish used for consumption. In 2008, the Tajik government claimed to have 14% of the world's untapped Uranium reserves within its borders and drew interest from China, Iran, and Russia to partner with in opening new mines.

The combination of land inequality, water scarcity, deforestation, and overgrazing leads to an estimated 70% of irrigated cropland being affected by soil erosion. Because the majority of rural populations are near landless, stripping steep slopes of water in mountainous areas is common practice, causing landslides and soil degradation. The effects of soil erosion include agricultural inefficiency, ecological destruction, and lower water quality from nitrification and increased pesticide use.

2% of Tajikistan's land is occupied by forest, a 23% decrease over the past century, two thirds of which occurred since Tajik independence. The combination of increased population and poverty in rural areas is the main cause, which results in desertification, reduced watershed protection, and landslides. The rural population in Tajikistan has doubled since 1979, causing competition for arable land and farmers spreading to forested areas. Additionally, high energy prices caused by lacking infrastructure have forced rural populations to turn to illegal logging practices for fuel during the winter. Tajikistan had a 2018 Forest Landscape Integrity Index mean score of 8.65/10, ranking it 21st globally out of 172 countries.

Due to high prices and dependence on imports from its Central Asian neighbors, Tajikistan faces significant energy shortages. During the Soviet Era, energy was shared regionally, however, since the dissolution of the USSR and fragmentation of its Central Asian territory, regional energy agreements did not continue, leaving Tajikistan with limited domestic energy resources. The destruction of infrastructure during the civil war and refusal of World Bank funds has also contributed. In 2010, 2% of Tajik households had access to central pipeline heating and 15% to pipeline gas. TALCO, Tajikistan's main aluminum producer, consumes 40% of output from Barqi Tojik, Tajikistan's national power company. accumulation of silt has already reduced the Nurek reservoir's capacity by 17%,
