According to the United States Geological Survey (USGS), water used for irrigation accounts for nearly 65 percent of the world’s freshwater withdrawals excluding thermoelectric power (1). Intensive useof nearly all good quality supplies means that new irrigation projectsand old projects seeking new or supplemental supplies must rely onlower quality and less desirable sources. Plants and animals also depend on a clean and plentiful water … Water plays development and growth of the contries. They can remain dry and appear somewhat dead for several years but, when rehydrated, they suddenly spring back to life (Le and McQueen-Mason 2006). Irrigating crops with contaminated water can then lead to contaminated food products which lead to illness when eaten. A safety margin is the factor that is added to account for uncertainties. Not only is water used to grow crops, it is also used to process agricultural products before they can be sent to … The importance of water relates to its essential functions in perpetuating both plant and animal life. It is a chemical reactant in photosynthesis hence vital to life. (1978) explained that under conditions that favor high absorption and low transpiration rates, there is build-up of high turgor pressure in the region of cell elongation which causes maximum swelling of the cells. 4th ed.
