1. INTRODUCTION:
“Water is precious, use it wisely” says a notice placed in the bathroom of a five star hotel in Karachi. There could not be a sounder piece of advice but it should be given not only to the guests of the five star hotels but also to the entire citizenry of Pakistan. Pakistan is rapidly moving to the situation when it will begin to be ranked among the countries that have severe shortages of fresh water. Wise use of this precious resource is one way of dealing with this crisis.
Man is a pre-eminently an animal good at gadgets. Man uses water much in the same way as other animals; he has to drink it constantly, washes in it frequently, and drowns in it occasionally – probably oftener than other terrestrial vertebrates. Without water, he dies as miserably as any other beast and with too much of it, as in floods, he is equally unable to cope. However, he excels other animals in that he has learned to utilize waterpower.
There are three basic uses of water in the modern civilization– agriculture, industry and human consumption. Using water wisely in these three uses is one way of saving the country from economic and social disaster.
Water is one of the most important natural resource and the major driving force for the economy of Pakistan. Only a few decades ago, Pakistan was considered to have abundance of good quality water. Now, however, in many other area of the world, population growth, economic development, rapid urbanization and industrialization, are applying continuous pressure on the already limited water resources of Pakistan.
Pakistan is now towards a serious shortage of water. In 1951, per capita surface water availability for irrigation was estimated at 5650 cubic metres; this declined sharply to only 1350 cubic metres per head in 2002. The minimum amount that should be available is 1000 cubic metres. 2012, Pakistan will have reached the stage of “acute water shortage”.
