sheaman42 discovered 3 months ago- Vienna - The world's population and agriculture hotspots are particularly sensitive to changes in the capacity of mountains to store water, geological scientists say. Both naturally occurring and man-made climate factors are affecting the capability of the world's mountain ranges to serve as sources for freshwater for adjacent lowlands. According to a recent study, about 7 per cent of the world's mountains are essential for providing downstream supply, said Daniel Viviroli of the University of Berne. This number is likely to increase, as 37 per cent provide an important supply that will grow more important in years to come. The dryer the lowland climate gets, the more important the mountains become, Vivrioli said. "If we want to know about the consequences for arid and semiarid areas, we need to be aware of the runoffs," he said, speaking on the sidelines of the annual meeting of the European Geosciences Union in Vienna. Precipitation runoff from the world's mountain ranges are the main contributor to freshwater resources in the surrounding lowlands and are essential for agriculture or drinking water. "Pressure on resources will increase in the subtropics, arid and semiarid regions," he said. Current research on climate change predicts that "wet places will get wetter and dry places will get dryer," climatologist Philip Mote from the University of Washington said.
