Climate change is affecting the
hydrological cycle all over the World. The effect on arid and semi-arid regions
is relatively more. The Middle East and North Africa region is one of the
biggest hyper-arid, semi-arid and arid zones in the world where the long-term
average precipitation does not exceed 166mm per year. The Tigris and Euphrates
basins are located within the northern part of the Middle East. Future
projections indicate the considerable reduction in water resources as a result
of drought and population growth. North Atlantic Oscillation (NAO) is
responsible for the change in climate over the Tigris and Euphrates basins.
This is causing a decrease in rainfall and a consequence decrease in the flow
of the rivers. In addition, the temperature is increasing. All these variables
are causing sea level rise, increasing dust storms and deletion of groundwater
resources. It is believed that quick actions are required to minimize the
effect of climate change. This includes prudent water resources planning and
good regional cooperation.
