DAKAR, 22 April 2009 (IRIN) - Water levels have declined over the past 50 years in some of the world's
largest rivers – including those serving large populations in China, West Africa and India – according to the US-based National Center for Atmospheric Research (NCAR).

those with rising levels by 2.5 to one. Water flows increased in sparsely populated areas near the Arctic Ocean, where snow and ice are rapidly melting. Freshwater that flows from rivers to oceans
help regulate the global climate, according to NCAR, which recommends close monitoring of oceans' freshwater content. pt/np © IRIN. All rights reserved. More humanitarian news and
