A new study warns that about thirty percent of the world's people may not have enough water by the year 2025. A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people liveintwenty-eight countries. Mostof the countries are in Africaand the Middle East.

P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected tohave serious water problems. The need for waterkeeps booming. Yet the amount of water on Earth stays the same.

Mr. Engelman says the population in countries that lack water is growing faster thanin other parts of the world. He says population growthin these countries will continue to increase. The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, which are carried in water. Lackof water may alsoresult in more international conflict. Countries may have to fight for water in the future. Some countries nowget sixty percent of their freshwater from other countries. This is true of Egypt, the Netherlands,Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would lower the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.

The Population Action International study gives several ways to solve the water problem. One way, it says, is to find ways to use water for more thanone purpose. Another way is to teach people to be careful not to waste water. Athird one is to use less water ofagriculture.

The report also says long-term way to solve the water problem must include controls on population growth. It says countries cannot have clean water unless they slow population growth by cutting down the number of children people have.
