Regional Water Scarcity : India

 

Based on per capita renewable water availability, India--the second most populous country in the world--has water enough to meet its people's needs. But despite an estimated 2,464 cubic meters per person per year, many of its nearly 900 million people suffer severe water shortages, in part as a result of uneven availability of water. Most rainfall comes during the monsoon season, from June to September, and levels of precipitation vary from 100 millimeters a year in the western parts of Rajasthan to over 9,000 millimeters in the northeastern state of Meghalaya.19 Floods and droughts are both common throughout the country.

 

India's vulnerability to regional water scarcity is well illustrated by the case of Rajasthan, a state in northwest India. Situated in one of the most inhospitable arid zones in the world, Rajasthan's northwest corner extends into the vast Thar Desert. With a wide range of temperatures and an unpredictable monsoon climate, drought and desertification are common, and water is a scarce commodity. Home to eight percent of India's population, Rajasthan can claim only one percent of the country's water resources, which come in the form of groundwater, limited rainfall, and a restricted share of waters that straddle state boundaries.20

 

Population growth in Rajasthan, as in the rest of India, has been rapid. In 1990, the state's population reached almost 44 million. And with only some 30 percent of couples using contraception, the state's total fertility rate, or average number of children per woman, remains at about 4.5. By the year 2000, Rajasthan's population is projected to increase to almost 55 million. In 1990 per capita water use in the state amounted to 562 cubic meters, a level nearly commensurate with absolute scarcity.20 With the projected increases in human numbers for the coming decade, acute shortages are imminent.

 

Even those who live in areas of high rainfall in India often face drought because landscapes have been denuded. Soil is compacted and most rainfall runs off before it can sink into the ground, increasing flooding. The region of Cheerapunji in Meghalaya, for example, receives among the highest levels of mean rainfall recorded in the world. Yet because of intense seasonal rainfall and the fact that the area's forests have been cleared in the past few decades to meet growing demands for agricultural land and housing, much of the runoff cannot be captured. The region now suffers from excessive flooding for three or four months and frequent droughts the rest of the year.21 With a rapidly growing population of 1.8 million, Cheerapunji's water shortages and desertification will likely worsen.
