Messages for Decision & Policy Makers and Water Managers on Adaptation to Climate Change through Integrated Water Resources Management IWRM at River Basin Level

As a result of global warming, the type, frequency and intensity of extreme events, such as tropical cyclones (including hurricanes and typhoons), floods, droughts and heavy precipitation events, are expected to rise even with relatively small average temperature increases. Changes in some types of extreme events have already been observed, for example, increases in the frequency and intensity of heat waves and heavy precipitation events.
