By 2025, the situation will worsen water shortages population will reach 28 billion to 3.3 billion. According to World Bank officials predict that in the next five years will be like water, like oil in the world running.

印度是一个干旱缺水十分严重的国家。淡水资源总量为28000亿立方米，占全球水资源的6％，仅次于巴西、加拿大和俄罗斯，居世界第四位，但人均占有量仅有2200立方米，只占世界平均水平的1／4，在世界上位列121位，是全球13个人均水资源最贫乏的国家之一。

India is a very serious drought and water shortage in the country. Freshwater resources of 2.8 trillion cubic meters total, accounting for 6% of global water resources, second only to Brazil, Canada and Russia, ranking fourth in the world, but only 2,200 cubic meters per capita, only the world average of 1 / 4, ranked 121 in the world, is the world's 13 most water-poor individuals are one of the countries. And uneven distribution of water resources in India, a lot of fresh water resources are concentrated in the South, the North South Water freshwater resources is only about 1/4. Statistics show that more than 600 cities in the country in more than half the problems facing different degrees of water shortage, the coastal city is no exception, and even more serious. India's urban water supply mainly groundwater or surface water-based, some cities due to over-exploitation of groundwater, causing groundwater levels decline, resulting in the formation of hundreds of square kilometers of some of the city's large funnel, so that seawater intrusion tens of kilometers. Some uncontrolled discharge of industrial wastewater, resulting in more than 80% of the groundwater, surface water contamination.
Experts warn: "After 20 years in India will not find drinkable water." According to Indian folk an influential think tank published a report, said: "As the industrial and agricultural development of India's increasing demand for water, India will face chronic water shortage problems." The Yellow River in the past 10 years in mid-drying, which in 1997 reached 226 days stop unexpectedly. Huaihe River flows through the densely populated areas of India also appeared drying up more than 90 days of the phenomenon. According to satellite photographs show that the country is gradually drying up of hundreds of lakes, some local rivers are gradually disappearing. More than 600 cities across the country, there are more than 300 cities short of water, of which there are 108 serious water shortage. Such as Beijing's per capita possession of water resources per capita possession of water resources for the world's 1/13, not as good as some of the arid Middle East countries.
India's total land resource-rich but per capita consumption is insufficient. According to data released by the Ministry of Land, India farmland, woodland, grassland total in 2004 were as high as 122,444,300 hectares, 235,047,000 hectares and 262,706,800 hectares, points out the world's first four, five and two, but per capita were about the current world average of 38%, 31% and 35%. To arable land, for example, India, t
