Through Central Asia, China and Deforestation

Kyrgyzstan is bordered on the east and southeast by China, on the north by Kazakhstan, on the west by Uzbekistan, and on the south by Tajikistan. The borders with Uzbekistan and Tajikistan in the Fergana Valley are rather complicated. One consequence of the Stalinist division of Central Asia into five republics is that many ethnic Kyrgyz people do not live in Kyrgyzstan. Three enclaves, legally part of the territory of Kyrgyzstan but geographically removed by several kilometers, have been established, two in Uzbekistan and one in Tajikistan.

The terrain of Kyrgyzstan is dominated by the Tian Shan and Pamir mountain systems, which together occupy about 65% of national territory. The Alay range portion of the Tian Shan system dominates the southwestern crescent of the country, and, to the east, the main Tian Shan range runs along the boundary between southern Kyrgyzstan and China before extending farther east into China's Xinjiang Uygur Autonomous Region. Kyrgyzstan's average elevation is 2,750 m (9,020 ft), ranging from 7,439 m (24,406 ft) at Peak Jengish Chokusu to 394 m (1,293 ft) in the Fergana Valley near Osh. Almost 90% of the country lies more than 1,500 m (4,900 ft) above sea level.

Topography and drainage

The mountains of Kyrgyzstan are geologically young, so that the physical terrain is marked by sharply uplifted peaks separated by deep valleys. There is also considerable glaciation, with the largest glacier being the Engilchek Glacier. Kyrgyzstan's 6,500 distinct glaciers are estimated to hold about 650 cubic kilometres (160 cu mi) of water and cover 8,048 square kilometers (5,000 square miles) or 4.2% of Kyrgyzstan. Only around the Chüy, Talas, and Fergana valleys is there relatively flat land suitable for large-scale agriculture.

Because the high peaks function as moisture catchers, Kyrgyzstan is relatively well watered by the streams that descend from them. None of the rivers of Kyrgyzstan are navigable, however. The majority are small, rapid, runoff streams. Most of Kyrgyzstan's rivers are tributaries of the Syr Darya, which has its headwaters in the western Tian Shan along the Chinese border. Another large runoff system forms the Chu (Chüy), which arises in northern Kyrgyzstan, then flows northwest and disappears into the deserts of southern Kazakhstan. Ysyk-Köl is the second largest body of water in Central Asia, after the Aral Sea, but the saline lake has been shrinking steadily, and its mineral content has been rising gradually. Kyrgyzstan has a total of about 2,000 lakes with a total surface area of 7,000 square kilometres (2,700 sq mi), mostly located at altitudes of 3,000 to 4,000 m (10,000 to 13,000 ft). Only the largest three, however, occupy more than 500 square kilometres (190 sq mi) each. The second- and third-largest lakes, Song-Köl and Chatyr-Köl (the latter of which also is saline), are located in the Naryn River Basin.

Natural disasters have been frequent and varied. Overgrazing and deforestation of steep mountain slopes have increased the occurrence of mudslides and avalanches, which occasionally have swallowed entire villages. In August 1992, a severe earthquake left several thousand people homeless in the southwestern city of Jalal-Abad.
