3.6 Climate change

Data from the Intergovernmental Panel on Climate Change (IPCC) climate change is projected to
alter the frequency and magnitude of both floods and droughts. The impact is expected to vary from
region to region. Some studies suggest that flood hazards will increase over more than half of the
globe, in particular in central and eastern Siberia, parts of Southeast Asia including India, tropical
Africa, and northern South America, but decreases are projected in parts of northern and Eastern
Europe, Anatolia, central and East Asia, central North America, and southern South America (limited
evidence, high agreement). These impacts are expected to impinge on water storage, decrease
water quality and threaten urban water infrastructures, while disrupting service and increasing
energy costs for operation and maintenance at both the local and the regional levels.
