A conference of African nations is beginning in Ghana 

to try to work out how to provide every African 

with clean water at an affordable price.

 The United Nations report to be considered by 

delegations in Accra says more than one billion people world-wide 

don’t have access to safe drinking water with half the global

 population lacking adequate sanitation.

 It says two million people,

 most in Africa die needlessly every year because water supply has not

 been properly managed. 

Experts say the problems toughen African development.

 The BBC correspondent says the challenge for the

 conference is to produce ideas involving all sectors of society, 

but which don’t cost a lot.

 But the emphasis on sustainability rather than short term fixes.
