ISTANBUL (AP) -- Worldwide demand for water is rising just as access to safe drinking water and sanitation remains inadequate in much of the developing world, the United Nations said Monday, calling for better management to alleviate water shortages.

Population growth and mobility, as well as increased energy production, especially of biofuels such as ethanol, are contributing to the high demand for water, UNESCO said on the first day of a global water forum in Istanbul, Turkey's largest city.
“With increasing shortages, good governance is more than ever essential for water management. Combating poverty also depends on our ability to invest in this resource,” said Koichiro Matsuura, director-general of the UN agency. He urged leaders who will gather for the G-8 summit in Italy in July to pledge investment in water resources to help prevent a “major water crisis.”
Thousands of activists, entrepreneurs, mayors, parliamentarians and business executives have gathered for the weeklong World Water Forum, which is held every three years to promote ideas about conserving, managing and supplying water. Climate change and the impact of the global economic meltdown are key issues on the agenda this year.
