By Amitabh Pal for the Progressive. The two big issues we are facing are climate change and water shortages. Water shortages are more imminent. They’re here now. We suddenly look around and realize that water tables are falling everywhere: throughout the high plains of the United States, for instance, in the Ogallala Aquifer. This is a huge source of water, but it has already been pumped out in Texas-Oklahoma.
Much of the water used in the world comes from aquifers. There are thirty-seven major aquifers. More than twenty of them have no major recharge at all. When they’re gone, they’re gone.
Over the last thirty years, numerous lakes and rivers have disappeared in the world, and that’s going to continue. Some of the larger rivers no longer make it to the sea, such as the Colorado River or the Yellow River. We’ve got to reshape the economy to make it much more water-efficient than it now is.
We know that there are already a number of countries that are running out of water. They’ve pumped their aquifers dry or they’re getting very close to it. This includes Saudi Arabia, Yemen, Syria, and Iraq. And in India, water tables are falling everywhere. The question is: What happens when wells start to run dry?
