#346 Conserving the life saving liquid

Conserving the life saving liquid

The most life saving liquid on this planet is water. Needless to say that without it, the possibility of life is completely a vague idea. Being a non-renewable resource, its depletion is a major concern for the mankind. A rapid rise in population has resulted in an over exploitation of it. Other causes of it can be global warming and unequal distribution of ground water. If we look at the distribution of water on Earth i.e Hydrosphere, we will find that Less than 3% of the water of Earth is freshwater, an amount that includes polar ice caps, glaciers, groundwater, surface water of rivers and freshwater lakes, and even atmospheric water. However, the amount of freshwater useable by people and other members of the biosphere is less than 0.7% of the total. This relatively small amount of available freshwater is recycled and purified by the action of processes within the hydrologic cycle.. All these reasons invite a need for conserving water.

According to the World Health Organization (WHO) of the United Nations, a minimum requirement of water for a person is about 5 gal (20 l)per day. This is the minimum amount needed for activities like physiological rehydration, cooking, washing, and other subsistence requirements. This carries a significant risk of developing such water-borne diseases as cholera, dysentery, polio, or typhoid, which kill about 25 million people per year. Both conservation and sanitation are obvious necessities in meeting the huge demand for freshwater.

Of all the freshwater used directly by humans, agricultural irrigation accounts for about 70% of the total. Since irrigation consumes about 70% of the total water, an effective method of conservation of water can be checked by controlling the activities pertaining to irrigation. Water conservation can be defined as a careful and judicious use of water to prolong and better the supply of water. Even though it appears to be in limelight because of the problems mentioned above yet this concept is very old.

Several methods have been proposed in the direction of conserving water such as rain water harvesting, lining water delivery systems with concrete or other impervious materials to minimize loss by leaking during transport, and by using drip-irrigation systems to minimize losses by evaporation, Subsurface irrigationXeriscaping ;or the cultivation of plants requiring little water such as cacti, succulents, and shrubs of semi-desert habitat,desalinize seawater etc

Recently several schemes have been proposed in the direction of conserving water. One of those schemes is scheme Atal Bhujal Yojana (ABY) formulated by the Union Government to tackle ever-deepening crisis of depleting groundwater level. The objective of scheme is to recharge ground water and create sufficient water storage for agricultural purposes. It also focuses on revival of surface water bodies so that ground water level can be increased, especially in the rural areas. This scheme will help farmers who have been severly affected by the acute shortage of ground water for past several years. Central Ground water board (CGWB) has given permission to Indian Institute of Science (IISc) to develop ground water flow models and preparation of aquifer management plans for parts of Karnataka.

We , as individuals, should take utmost care in personal sphere to prevent its misuse. We should try to use every drop of it judiciously. Instead of simply throwing away the water when left in the glass after drinking, we can use that to water plants.  Children should be taught not to waste them and use them when in need.We should prevent unnecessary leakage of water through taps and pipes and get them repaired. We should not leave the taps in an opened state when not being used. We should focus on collecting rain water by putting the containers below the sources of dripping water like roofs, terrace etc

Due to population expansion, the natural resources are depleting day by day and unfortunately water is one of them. We should take care to save every drop of this live saving liquid so that we don’t have to face the dearth of it or else the future of our next generation will be at peril.
