Corruption is denying the poor in Africa and Asia access to water and making households in Nairobi face higher utility bills than those in New York, a report by Transparency International released Wednesday said. The anti-graft watchdog said corruption was a critical but often overlooked factor in the global water crisis that has left a fifth of the world's population without guaranteed access to drinking water. The chairwoman of Transparency International, Huguette Labelle, warned that governments ignore water corruption at their own peril as it leads to waste and risks undermining their efforts to fight growing food shortages.
