Critical worldwide shortages could lead to water wars

Get ready for the water wars.
Most of the world’s population takes water for granted, just like air — two life-sustaining substances. After all, the human body is nearly two-thirds water.
But a Hindustan Times blogger said that in India right now, as in many other places around the globe, drinkable water has become such a “precious commodity” that it’s dragging the world into “water wars.”
Climate change is drying up lakes and rivers almost everywhere. In Australia, an unprecedented heat wave brought on massive wildfires and critical water shortages.
As water grows scarce, more countries are building dams on rivers to hog most of the water for themselves, depriving the nations downstream. Already, Egypt has threatened to bomb the Grand Renaissance Dam upstream on the Nile River in Ethiopia.
And as the Earth’s population crossed the 7 billion mark last year, more water sources are so polluted that drinking it can kill you. Government and private estimates indicate that tens of thousands of children die each day from contaminated water.
By most estimates, half the world’s people live in places where clean water is not easily available. Bangalore, India, once had 400 lakes in its vicinity. Now, only 40 are left, and all are polluted.
Hence the fights. One of the biggest areas of conflict is the India-Pakistan-China nexus. Multiple rivers intertwine the countries, and all three are building dams to keep much of the water for themselves.
China has built more dams than any other nation, making numerous countries angry because Chinese rivers flow into many adjacent states. And yet, even with 14 downstream border states, China refuses to agree to any water treaties. Now China has approved plans to build 54 more dams on rivers, many of which serve as the lifeblood of neighboring states.
In China’s north, “desertification” is turning vast areas into dust bowls. So the government is trying to divert 6 trillion gallons of water per year from the Yangtze River to reclaim the area, worrying people in other parts of China who rely on the Yangtze for their water.
In Iran, farmers in one region destroyed a water-pump station that was carrying water away from their area to the city of Yazd.
A recent NASA study warned of an “alarming rate of decrease in total water storage” in Iraq’s “Tigris and Euphrates river basins, which currently have the second fastest rate of groundwater storage loss on Earth, after India.” The report warned that water scarcity could become another cause of conflict.
Egypt’s military threats against Ethiopia begin to make sense when you realize that Egypt’s 84 million people draw 95 percent of their water from the Nile River. A common saying is that without the Nile there is no Egypt.
The U.S. House of Representatives recently held a hearing on water shortages and other threats in Central Asia.
In Sri Lanka this month, the Daily News wrote: “We can live many days without food, but without water it is about three days.” Still, “we can’t seem to get the right water to the right people at the right time. More people have access to cell phones than safe water.”
With ever-rising temperatures, more water evaporates and returns to the ground as rain. But most of it falls into the oceans. That’s one reason sea levels are rising worldwide, threatening vast coastal areas.
But that leaves the world with an expensive but straightforward solution to the water-shortage problem everywhere. Build desalination plants, as Australia, Israel, Saudi Arabia and other well-off, water-stressed states are already doing.
Soon enough, whichever country starts marketing these critically important plants worldwide will make a lot of money and grow to be seen as a savior for millions of the world’s people.
