More planning needed in the use of waterWater is becoming scarce in several parts of the country. Unless a real planning is done during the coming years, most parts of the country will face its consequences.
The concept 'virtual water' has generally been accepted by all. Through this it is possible to calculate the requirement of water for the production of every item, either naturally or artificially. The concept that the water on earth is always rejuvenated by rain and snow is also changing. Based on the new concept of 'peak water', water can be considered as naturally regenerated or not; or those possible to be regenerated or not. Based on this water source can be differentiated.
Global warming, waste generation, wrong-developmental activities and such other things affect the weather conditions. Rainfall quantity go on changing.
Based on virtual water theory three thousand litre of water is used to produce one Kg of rice. Assuming the price of one litre of water as Rs.20/-, sixty thousand Rupees are needed to produce one Kg of rice ! Production of rice at this cost makes one think of importing the same from other places where water is available in plenty. That is the latest economic theory regarding rice production. This approach naturally will discourage the rice production trend in places where there are water shortage.
This approach calls for a planning for water usage. Priorities must be fixed regarding the use of water. Presently the priorities are given for drinking, agriculture, industries, and the like. These direct diversion of water must be replaced with stress being given to the protection of the ecosystem such that water is available for all purposes. Several countries are changing into this direction.
