West Africa has the lowest coverage of drinking water and sanitation in the world, and the numbers are rising not falling, according to the United Nations children’s agency (UNICEF). As populations have boomed throughout the region, the absolute number of people without drinking water increased from 124 million in 1990 to 157 million in 2004, and the number without sanitation from 173 million to 225 million, according to a UNICEF report released on Friday.
