I India: India prays for rain as water wars break out
It was a little after 8pm when the water started flowing through the pipe running beneath the dirt streets of Bhopal's Sanjay Nagar slum. After days without a drop of water, the Malviya family were the first to reach the hole they had drilled in the pipe, filling what containers they had as quickly as they could. Within minutes, three of them were dead, hacked to death by angry neighbours who accused them of stealing water.
In Bhopal, and across much of northern India, a late monsoon and the driest June for 83 years are exacerbating the effects of a widespread drought and setting neighbour against neighbour in a desperate fight for survival.
India's vast farming economy is on the verge of crisis. The lack of rain has hit northern areas most, but even in Mumbai, which has experienced heavy rainfall and flooding, authorities were forced to cut the water supply by 30% last week as levels in the lakes serving the city ran perilously low.
California's San Joaquin Valley has lost 60 million acre-feet of groundwater since 1961, according to a new federal study. That's enough water for 60 Folsom reservoirs.
This is among the findings in a massive study of groundwater in California's Central Valley by the U.S. Geological Survey. It helps shed light on the mysteries and dangers of California's groundwater consumption, which is mostly unregulated.
According to the study, groundwater pumping continues to cause the valley floor to sink, a problem known as subsidence. This threatens the stability of surface structures such as the California Aqueduct, which delivers drinking water to more than 20 million people.
The Central Valley is America's largest farming region; it's also the single-largest zone of groundwater pumping.

Since the overpumping of aquifers is occurring in many countries more or less simultaneously, the depletion of aquifers and the resulting harvest cutbacks could come at roughly the same time. And the accelerating depletion of aquifers means this day may come soon, creating potentially unmanageable food scarcity.
While falling water tables are largely hidden, rivers that are drained dry before they reach the sea are highly visible. Two rivers where this phenomenon can be seen are the Colorado, the major river in the southwestern United States, and the Yellow, the largest river in northern China. Other large rivers that either run dry or are reduced to a mere trickle during the dry season are the Nile, the lifeline of Egypt; the Indus, which supplies most of Pakistan’s irrigation water; and the Ganges in India’s densely populated Gangetic basin. Many smaller rivers have disappeared entirely.
