1.Statistics show that China has a total amount of

trillion cubic meters of water resource, second only to Brazil, Russia and Canada, ranking the fourth (to be updated) in the world. But when divided by

billion, our average per-capita share of water resource only amounts to about one quarter of the world’s averag e.

2.We have always been heavily burden with the problem

of water shortage. It is said that the 661 large and medium-sized cities nationwide, about two-thirds are suffering from acute shortage of water. Beijing is

a good example in point. It not only lacks surface

water, even its underground water is dangerously low.

It is reported to have dropped by 90 meters. Some scholars suggest we move our capital to some other place. This is of course unfeasible/ unrealistic, but the message is clear.

3.Our water resources first of all are not evenly

distributed in time or space. They are either too much, causing floods, or too little, causing droughts.

4.In spite of the impressive progress we have achieved

in the past years, we are still far from effectively harnessing our rivers, lakes, and reservoirs. Soil erosion and desertification are increasingly threatening our economy and people’s life. Many of our rivers no longer flow to the sea. In 1998, the

Yellow River failed to have enough water to flow to the sea for 212 days.

5.Traditionally, our water resources have mainly been

used to irrigate land but, in recent years, demands on water for industrial and domestic use have also been sharply on the rise. They have seriously outgrown supplies.

6.Today our scarce water resources are becoming even

scarcer because a lot of water is being wasted on capacious power showers, flush lavatories, and golf rinks. Moreover, a lot of water being polluted.

7. These two rivers both have their headwater in the

country. It therefore makes water an issue for potential serious dispute between the two countries.

8.In recent years, we have pinned great hopes on the

projects to divert water from the south to the north, hopping that it will once and for all solve our flood problem in the south and the drought problem in the north. But there are scholars whose opinions differ.

They warn us that immunity of the Yangtze to droughts cannot be taken for granted.
