A new study warns that about thirty percent of the world’s people may not have enough water by the year 2025.

An American organization called Population Action International did the new study. It was more than three hundred and thirty-five million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or in the Middle East.

Population Action International researcher Robert Engelman says by the year 2025, about three thousand million people lack water. At least 18 more countries are expected to have serious water problems. The demand for water keeps increasing. Yet the amount of water on the earth the same. Mr Engelman says the population in countries that lack water is growing in these countries will continue to increase.

The report says lack of water in the future may result several problems. It may increase health problems. Lack of water often means drinking water is not safe. Mr Engelman says there are problems all over the world because of diseases such as cholera that are carried in water.

Lack of water also may result in more international conflict. Countries may have to fight for water in the future. Some countries, such as Syria, Sudan, Cambodia, and so on, now get sixty percent of their fresh water from other countries. And the report says lack of water would affect the ability to improve their economies. This is because industries often need a large amount of water.

The Population Action International study gives several ways to solve the water problem. One way is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third is to use less water for agriculture. The report also says long-term solutions to the water problem must include controls on population growth.
