WATER RESOURCES

Water is an essential element to our everyday existence. Its role is vital in the sustenance of all life forms, as well as in agricultural, industrial, households, recreational and environmental activities. As population continues to rise, so does the demand for fresh water too. Water is a major factor shaping the natural environment. It has a long-term influence on the vegetation, fauna, and shape of the landscape and on various ecosystems.
