Water squabbles irrigate tensions in Central Asia

By Maria Golovnina

VAKHDAT, Tajikistan (Reuters) - Under a scorching sun, an exhausted Tajik woman looks at a drying trickle of irrigation water running across her cotton field.

"Water is all we have," said Gulbakhor, a 55-year-old mother of nine, pointing at swathes of parched land stretching towards the austere mountains of central Tajikistan. She did not want to give her last name.

"But all the ponds and rivers are dry. We need to water our crop but we don't have enough even for ourselves."

Gulbakhor's despair, shared by millions of Tajiks in this tiny ex-Soviet nation north of Afghanistan, reflects a growing sense of alarm throughout Central Asia where stability depends on the region's scarcest and most precious commodity: water.

From tiny irrigation canals such as Gulbakhor's to the powerful Soviet-era hydroelectric plants, water is the source of misery and celebration in a poor region already overflowing with political and ethnic tension.

Central Asia is one of the world's driest places where, thanks to 70 years of Soviet planning, thirsty crops such as cotton and grain remain the main livelihood for most of the 58 million people.

Disputes over cross-border water use have simmered for years in this sprawling mass of land wedged between Iran, Russia and China. Afghanistan, linked to Central Asia by the Amu Daria river, is adding to the tension by claiming its own share of the water.

Water shortages are causing concern the world over, because of rising demand, climate change and swelling populations.
