Water Resources
Water is an essential resource for all life on the planet. Of the water resources on Earth only three per cent of it is not salty and two-thirds of the freshwater is locked up in ice caps and glaciers. Of the remaining one per cent, a fifth is in remote, inaccessible areas and much seasonal rainfall in monsoonal deluges and floods cannot easily be used. At present only about 0.08 per cent of all the world’s fresh water is exploited by mankind in ever increasing demand for sanitation, drinking, manufacturing, leisure and agriculture.
Much effort in water management is directed at optimising the use of water and in minimising the environmental impact of water use on the natural environment.
Successful management of any resources requires accurate knowledge of the resource available, the uses to which it may be put, the competing demands for the resource, measures to and processes to evaluate the significance and worth of competing demands and mechanisms to translate policy decisions into actions on the ground.
For water as a resource this is particularly difficult since sources of water can cross many national boundaries and the uses of water include many that are difficult to assign financial value to and may also be difficult to manage in conventional terms. Examples include rare species or ecosystems or the very long term value of ancient ground water reserves.

Famous quotes containing the words water and/or resources:
“Thales claimed that everything was water. He also put wine into water to sterilize it. Did he really believe he was putting water into water to sterilize it? Parmenides, like most Greeks, knew that wine was not water. But while lifting a glass of wine to his lips, he denied that motion was possible. Did he really believe that the glass was not moving when he lifted it?”
—Avrum Stroll (b. 1921)
“Your children don’t have equal talents now and they won’t have equal opportunities later in life. You may be able to divide resources equally in childhood, but your best efforts won’t succeed in shielding them from personal or physical crises. . . . Your heart will be broken a thousand times if you really expect to equalize your children’s happiness by striving to love them equally.”
—Marianne E. Neifert (20th century)
