Turkmenistan


Note: Turkmenistan was officially included amongst the countries of MO's Regional Office for the Near East in March 1996. For the present publication, has not been possible to perform an in-depth survey of the information on water and irrigation and so the data presented below are probably very incomplete.

GEOGRAPHY AND POPULATION

Turkmenistan is a landlocked country in Central Asia, bordered in the west by the Caspian Sea, in the north-west by Kazakhstan, in the north-east by Uzbekistan, in the south-east by Afghanistan and in the south-west by Iran. It formally declared its independence from the USSR in October 1991. The total area of the country is 488 100 km. The Kara Kum desert comprises 80% of the total area of the country. In the south west, along the border with Iran, lies the Kopetdag mountain chain with its highest peak at 2 919 metres. The Kougitangtau mountain with a peak at 3 137 metres is located in the east at the border with Uzbekistan.

In 1993, the total cultivated area was estimated at 1 480 000 ha, which is 3 % of the total area of the country. About 95% consisted of annual crops, and 5% of permanent crops, including vineyards, pistachio nuts, figs and olives.

The total population is about 4.1 million (1995), of which 55% is rural. Annual population growth was estimated at almost 2% in 1995, while it was 2.5% during the period 1979-89. In 1994, 44 % of the total labour force was engaged in agriculture, including forestry. Agriculture accounts for almost 50% of the country's GDP.

CLIMATE AND WATER RESOURCES

Climate

The climate of Turkmenistan is of the subtropical desert type. In the Kara Kum desert, rainfall is so rare, that people remember single rainstorms that occurred years ago.

Water resources

The country has few internal renewable water resources, estimated at 1 km/year. The Amu Darya is the largest incoming river with an annual flow estimated at 70 km. It enters the country in the south-east after running along the border between Afghanistan and Turkmenistan over a length of about 60 km. It flows to the north-east and runs along the border between Turkmenistan and Uzbekistan for about 200 km before entering Uzbekistan.

Several smaller rivers (the Murgap, the Tejen, the Atrek) descend from the Kopetdag and other mountains in the south. The central and western regions have no significant natural waterways.

The Kara Kum canal, the longest irrigation canal in the world, 1300 km long, was constructed during the 1950s. Its inlet at the Amu Darya river is located just at the point where the river enters the country. It brings water to the oases in the south and to the capital Asghabat.

Total water withdrawal was 22.8 km in 1989, of which 91% for agricultural purposes (Figure 1). Contamination of surface water and groundwater with agricultural chemicals and pesticides is a serious problem. An inadequate supply of clean drinking water is a serious health hazard in Turkmenistan.

IRRIGATION AND DRAINAGE DEVELOPMENT

Turkmenistan is largely a desert country with nomadic cattle raising and intensive agriculture in the oases, irrigated with water from the Kara Kum canal in the south and the Tashauz canal in the north. Irrigation is estimated to cover around 1 300000 ha, which is 88% of the cultivated area. About half of the irrigated area is estimated to be planted with cotton, making Turkmenistan the world's tenth largest cotton producer. Other irrigated crops are cereals (mainly wheat), vegetables and fruit.

The unprotected banks of the Kara Kum canal have caused massive waterlogging and salinization of the surrounding land. It is estimated that some 46% of the cultivated land is now suffering from severe salinization. The land is also heavily polluted because of the overuse of pesticides and fertilizers.

INSTITUTIONAL ENVIRONMENT

TRENDS TN WATER RESOURCES MANAGEMENT

One of the most serious policy dilemmas facing countries in the central Asian region concerns the environmental problems of the Aral Sea basin as a result of the absence of environmental considerations in agricultural practices, industrial development and waste management.

The special problems related to the Aral Sea desiccation are addressed through a potable water and a regional water management programme. Turkmenistan is one of the beneficiaries of the Central Asian Environmental Plan which seeks to ensure potable drinking water and improve water management throughout the area. It is also concerned with cooperation and water policy reforms to solve the Aral Sea disaster.
