     Valuing water

     Human beings use a little less than half the water available worldwide. Yet shortages and droughts (干旱)

are causing starvation and poverty in some areas, and industrial and agricultural by-products are polluting water

supplies. Since the world's population is expected to double in the next 51 years, many experts think we are on

the edge of a widespread water crisis.

     But that doesn't have to be the result. Water shortages do not have to trouble the world-if we start valuing

water more than we have in the past. Just as we began to value petrol more after the 1970s oil crisis, today we must start looking at water from a fresh economic view. We can no longer afford to consider water a nearly

free resource of which we can use as much as we like in any way we want.

     Instead, for all uses except the demand of the poor, governments should price water to reflect its real value. This means charging a fee for the water itself as well as for the supply costs.

     Governments should also protect this source by providing water in more economically and environmentally

sound ways. For example, often the cheapest way to provide irrigation (灌溉) water in the dry places is through small-scale projects, such as gathering rainfall in depressions(凹地) and pumping it to nearby cropland.

     No matter what steps governments take to provide water more efficiently, they must change their ways to

use water. Rather than control hundreds or even thousands of local, regional agencies that watch water use,

countries should set up central authorities to manage water policy.
