Water Resources Management in the Republic of Tajikistan
Abstract
Tajikistan is a mountainous country with 93% of its territory occupied by mountains. The average annual precipitation in the country is around 760 mm, varying from less than 100 mm in some isolated pockets in the South, to more than 2400 mm on the Fedchenko glacier. Glaciers and rivers compose 910 km3 water resources. The 93% of total water resources are in solid form. Subsequently, the climate change (variation of temperature, precipitation and evapotranspiration) and human activities (the activities of irrigation and energy generation) has the significant influence to the spatiotemporal distribution of local water resources. The annual average temperature has been observed with an increasing rate of 0.0072-0.0164 degree per year. The annual total precipitation annually varies from -0.0021-0.1025 mm per year. Subsequently, the glacier area has been reduced to 60% since last century. The surrounding countries also have high demand of water resources. The global changes bring the great challenges to local residences, such as more natural disasters, less water availabilities, desertification and so on, which the researchers and authorities has to be aware of.
