India's worsening water crisis

Ram Mashru in the Diplomat: In northern India, groundwater supplies are being depleted faster than natural processes can replenish them. According to The World Bank, India is the largest user of ground water in the world, after China. If something is not done soon, an estimated 114 million Indians will soon face desperate domestic, agricultural and industrial shortages.

What is causing this? “Human activities”: primarily wasteful water use (mainly agricultural over-exploitation), a lack of sustainable water-management policies and insufficient public investment. These failings have each been exacerbated by rapid population growth, increasing population density and climate change.

South Asia is a desperately water-insecure region, and India’s shortages are part of a wider continental crisis. According to a recent report authored by UN climate scientists, coastal areas in Asia will be among the worst affected by climate change. Hundreds of millions of people across East, Southeast and South Asia, the report concluded, will be affected by flooding, droughts, famine, increases in the costs of food and energy, and rising sea levels.

Groundwater serves as a vital buffer against the volatility of monsoon rains, and India’s falling water table therefore threatens catastrophe. 60 percent of north India’s irrigated agriculture is dependent on ground water, as is 85 percent of the region’s drinking water. The World Bank predicts that India only has 20 years before its aquifers will reach “critical condition” – when demand for water will outstrip supply – an eventuality that will devastate the region’s food security, economic growth and livelihoods....
