Article Outline
Turkmenistan has substantial reserves of oil and natural gas in the Caspian Sea area and in the Garagum desert. Other natural resources include deposits of coal, sulfur, magnesium, and salt. Only 5 percent of the country’s total land area is cultivated, nearly all of which (18,500 sq km; 7,143 sq mi) is irrigated.
The climate of Turkmenistan is desert continental, with cold winters and very hot summers. For most of the country, the average daily temperature in January ranges from -6° to 5°C (21° to 41°F), while in July it is 27° to 32°C (81° to 90°F). Average annual precipitation ranges from 80 to 400 mm (3 to 16 in), although two-thirds of the country receives 150 mm (6 in) or less.
Turkmenistan suffers from a number of serious environmental problems, many of which stem from decades of economic mismanagement under Soviet planning. Excessive irrigation has severely degraded soil and water quality in Turkmenistan. Irrigation of the naturally saline soil has brought underground salts to the surface, making the soil even more saline while also making irrigation more necessary. Thus, excessive irrigation has contributed to desertification (a process whereby arable land becomes desert, or arid salt flats). In addition, Turkmenistan’s soil has become heavily contaminated with agricultural chemicals, such as pesticides and herbicides, that are applied in large doses to cotton crops. These agricultural chemicals also contaminate the water supply, mainly through irrigation runoff. Untreated wastewater also pollutes groundwater, although there has been some improvement in northern Turkmenistan since the 1995 opening of a new water-treatment plant near Dashhowuz, constructed with aid from the United States. Since the late 1980s environmental awareness has been growing in Turkmenistan. The government has a ministry in charge of environmental protection, but only a small portion of the national budget is allocated for this purpose. Turkmenistan is also involved in a regional effort to address the problem of the Aral Sea. This saltwater lake in Uzbekistan and Kazakhstan has shrunk to less than half of its former size since the early 1960s. The greatest single contributor to the drying of the Aral is Turkmenistan’s Garagum Canal, which receives more water from the Amu Darya (one of two inflow sources for the Aral) than any other irrigation structure in the Aral Sea basin. The drying of the Aral Sea is considered one of the worst ecological disasters in the world.
Turkmenistan is the least populated of the five former Soviet republics in Central Asia. In 2007 the country had an estimated population of about 5,136,262, giving it an average population density of 11 persons per sq km (27 per sq mi). Settlement is concentrated along rivers, canals, and other oases; the Garagum desert and the mountains are sparsely populated. Some 46 percent of Turkmenistan’s population lives in urban areas. Ashgabat, the capital, is located on the Garagum Canal in south central Turkmenistan. Other large cities are Chärjew, located on the Amu Darya in the east, and Dashhowuz, located in the north.
With Turkmens constituting 77 percent of the population, Turkmenistan is the most ethnically homogeneous of the Central Asian republics. Uzbeks make up the largest minority group, with about 9 percent of the population. Other ethnic groups include Russians, Kazakhs, Tatars, Ukrainians, Azeris (ethnic Azerbaijanis), Armenians, and Baluch. In 1993 a bilateral treaty between Turkmenistan and Russia granted dual citizenship to Russians in the republic. At the 1995 census Russians constituted about 7 percent of the population, but since then many have chosen to immigrate to Russia. In 2003 dual citizenship was abolished, prompting many more of the country’s remaining Russians to leave for Russia. Turkmens have retained centuries-old tribal allegiances that tend to be stronger than their sense of nationhood. As a result, tribal-based hostilities are far more pronounced than interethnic tensions. To date no tribal unrest has developed against the government, which has carefully avoided obvious favoritism toward any one tribe and generally worked to suppress tribal identification. The three largest Turkmen tribes are the Tekke in the central part of the country, the Ersary in the southeast, and the Yomud in the west.
