Mean changes in runoff
Year:
2010
Author:
Nieves López Izquierdo, Associate Consultant UNEP/GRID-Arendal
Description:
Changes in precipitation and temperature influence changes in runoff and the availability of water. Results from models of changes in runoff are consistent with predictions for precipitation. For 2090-2099, in areas for which increases in the rainfall regimen are expected, increases in runoff are also projected. The anticipated changes in runoff are based on the A1B climate change scenario which assumes future rapid demographic and economic growth, introduction of new and more efficient technologies, accompanied by a balanced use of all types of energy sources, as with changes in temperature and precipitation. This particular scenario envisions that the greatest changes (between 10% and 30%) will occur in eastern Argentina and southern Brazil, while the most significant decreases (between 10% and 30%) are predicted for Mexico, Central America and Chile.
