Turkmenistan - Environment
According to estimates, as a result of desertification processes and pollution, biological productivity of the ecological systems in Turkmenistan has declined by 30 to 50 percent in recent decades. The Garagum and Qizilqum deserts are expanding at a rate surpassed on a planetary scale only by the desertification process in the Sahara and Sahel regions of Africa. Between 800,000 and 1,000,000 hectares of new desert now appears per year in Central Asia.
The type of desertification caused by year-round pasturing of cattle has been termed the most devastating in Central Asia, with the gravest situations in Turkmenistan and the Kazak steppe along the eastern and northern coasts of the Caspian Sea. Wind erosion and desertification also are severe in settled areas along the Garagum Canal; planted windbreaks have died because of soil waterlogging and/or salinization. Other factors promoting desertification are the inadequacy of the collector-drainage system built in the 1950s and inappropriate application of chemicals.
The most productive cotton lands in Turkmenistan (the middle and lower Amu Darya and the Murgap oasis) receive as much as 250 kilograms of fertilizer per hectare, compared with the average application of thirty kilograms per hectare. Furthermore, most fertilizers are so poorly applied that experts have estimated that only 15 to 40 percent of the chemicals can be absorbed by cotton plants, while the remainder washes into the soil and subsequently into the groundwater. Cotton also uses far more pesticides and defoliants than other crops, and application of these chemicals often is mishandled by farmers. For example, local herdsmen, unaware of the danger of DDT, have reportedly mixed the pesticide with water and applied it to their faces to keep away mosquitoes. In the late 1980s, a drive began in Central Asia to reduce agrochemical usage. In Turkmenistan the campaign reduced fertilizer use 30 percent between 1988 and 1989. In the early 1990s, use of some pesticides and defoliants declined drastically because of the country's shortage of hard currency.
The Aral Sea
Turkmenistan both contributes to and suffers from the consequences of the desiccation of the Aral Sea. Because of excessive irrigation, Turkmen agriculture contributes to the steady drawdown of sea levels. In turn, the Aral Sea's desiccation, which had shrunk that body of water by an estimated 59,000 square kilometers by 1994, profoundly affects economic productivity and the health of the population of the republic. Besides the cost of ameliorating damaged areas and the loss of at least part of the initial investment in them, salinization and chemicalization of land have reduced agricultural productivity in Central Asia by an estimated 20 to 25 percent. Poor drinking water is the main health risk posed by such environmental degradation. In Dashhowuz Province, which has suffered the greatest ecological damage from the Aral Sea's desiccation, bacteria levels in drinking water exceeded ten times the sanitary level; 70 percent of the population has experienced illnesses, many with hepatitis, and infant mortality is high (see table 5, Appendix; Health Conditions, this ch.). Experts have warned that inhabitants will have to evacuate the province by the end of the century unless a comprehensive cleanup program is undertaken. Turkmenistan has announced plans to clean up some of the Aral Sea fallout with financial support from the World Bank (see Glossary).
Since the collapse of the Soviet Union, environmental regulation is largely unchanged in Turkmenistan. The new government created the Ministry of Natural Resources Use and Environmental Protection in July 1992, with departments responsible for environmental protection, protection of flora and fauna, forestry, hydrometeorology, and administrative planning. Like other CIS republics, Turkmenistan has established an Environmental Fund based on revenues collected from environmental fines, but the fines generally are too low to accumulate significant revenue. Thanks to the former Soviet system of game preserves and the efforts of the Society for Nature Conservation and the Academy of Sciences, flora and fauna receive some protection in the republic; however, "hard-currency hunts" by wealthy Western and Arab businesspeople already are depleting animals on preserves.
The most irreparable type of desertification is the salinization process that forms marshy salt flats. A major factor that contributes to these conditions is inefficient use of water because of weak regulation and failure to charge for water that is used. Efficiency in application of water to the fields is low, but the main problem is leakage in main and secondary canals, especially Turkmenistan's main canal, the Garagum Canal. Nearly half of the canal's water seeps out into lakes and salt swamps along its path. Excessive irrigation brings salts to the surface, forming salt marshes that dry into unusable clay flats. In 1989 Turkmenistan's Institute for Desert Studies claimed that the area of such flats had reached one million hectares.
