1.Statistics show that China has a total amount of

2.8 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 1.3 billion, our average per-capita share of water resource only amounts to about one quarter of the world ’ s average.

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 ’lifes. 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.
