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:
“We can never part with it; the mind loves its old home: as water to our thirst, so is the rock, the ground, to our eyes, and hands, and feet. It is firm water: it is cold flame: what health, what affinity!”
—Ralph Waldo Emerson (1803–1882)
“Everywhere we are told that our human resources are all to be used, that our civilization itself means the uses of everything it has—the inventions, the histories, every scrap of fact. But there is one kind of knowledge—infinitely precious, time- resistant more than monuments, here to be passed between the generations in any way it may be: never to be used. And that is poetry.”
—Muriel Rukeyser (1913–1980)
