"As free as the land, air and water" is an age-old expression, which
men have used for hundreds of years to signify the things that nature has bountifully
provided, as contrasted to the type of wealth that has a tangible value, usually
as a result of human efforts in reworking natural elements. But today the old
phrase is largely empty. It has lost most of its original significance and at
present water has become such a scarce resource that it is called "Liquid
Gold" in many parts of the world, especially in the Coimbatore District of
Tamil Nadu, India. It is needless to say that man simply cannot live without water.
He must have it to drink, to meet domestic needs, to raise crops and to cooperate
his manufacturing industries. And the demand for water is steadily increasing
as civilization becomes more and more industrialized.
The place of water in the agricultural and in the overall economy is clearly
established. It is indispensable to any form of life and action. It can be man's
greatest friend or one of his most destructive enemies. Under control, it performs
a host of vital tasks in addition to achieving its final and supreme purpose in
providing man with a resource necessary to life itself. Uncontrolled, it wreaks
havoc with floods and carries our most precious top soil out to sea.
Taking all these elements into account and in looking to the future to 2000
A.D. and beyond, we must carefully plan and harness every drop of available water
in the dry areas. If we should fail to act now, with intelligence and decision,
we would place our children in a position of deadly peril. There are several avenues
of approach and all of them must be explored and used to the fullest practicable
extent. One technique among these is water harvesting.
