Lake's disappearance puts 30 million at risk, U.N. agency warns

(CNN) - Up to 30 million people are facing "a humanitarian disaster" due to the shrinking of one of Africa's biggest lakes, a United Nations agency warned Thursday.

Lake Chad was about the size of Maryland - bigger than Israel or Kuwait - in 1963, satellite images show. By 2001, it covered less than one-fifth of that area - making it smaller than Delaware or Mauritius.

The drying-up of the shallow lake is fueling conflict and migration, the U.N.'s Food and Agriculture Organization said.

Once one of the biggest bodies of water in the world, it could disappear entirely in about 20 years, the FAO said, citing NASA forecasts.

"The humanitarian disaster that could follow the ecological catastrophe needs urgent interventions," said Parviz Koohafkan, director of Land and Water Division of FAO in a statement. "The tragic disappearance of Lake Chad has to be stopped and the livelihoods of millions of people living in this vast area should be safeguarded.

"In addition to an approximately 60 percent decline in fish production, there has been degradation of pasturelands, leading to a shortage of animal feed estimated at 45 percent in certain places in 2006, reduction in livestock and biodiversity," the agency said.

The disappearance of the lake is being caused by climate change, population pressure and natural variations in climate, the FAO said.

Two rivers which feed the lake, the Chari and Logone, have been significantly reduced in the last 40 years, the agency said.

The organization will unveil the results of a study into the diversion of the Oubangui river in an effort to help Lake Chad at a conference, "Saving Lake Chad," in Rome, Italy on Friday.

The lake borders on Cameroon, Chad, Niger and Nigeria, one of Africa's most populous countries. It measured about 25,000 square kilometers (9,652 square miles) in 1963 and 1,500 square kilometers (579 square miles) in 2001 - just under 17 percent its size 38 years earlier.

Lake Chad is only one of many inland bodies of water which are drying up. Similar warnings have been issued about lakes in Mexico, Russia and elsewhere.
