afrol News, 26 August - Between 75 and 250 million people in Africa stand at the risk of being faced with a serious water supply deficit by 2020, a Ghanaian environmental protection agency director predicted.

William Kojo Agyemang-Bonsu told the United Nations conference on climate change in the capital Accra that "agriculture outputs in some countries could suffer a 50% decrease due to the effects of climate change.

He blamed human activities, which increased by 70% between 1970 and 2004, for causing climate change thus resulting to a rise in sea level.

"The average world rate of the rise in sea level is between 1.8cm and 3.1cm per annum from 1961 to 1993," he said, adding, "Forecasts indicate that the rise in the sea level will be between 18cm and 59cm in the end of the 21st century."

While calling for a stabilisation of the levels of greenhouse gas emissions, the Ghanaian expert said climate change involves a risk management process which includes both subduing and adapting to it.
