WATER AND ADAPTATION TO CLIMATE CHANGE
IN THE ARAB REGION

Introduction
Climate change (CC) refers to a change in the state of the climate that can be identified by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer. It refers to any change in climate over time, whether due to natural variability or as a result of human activity (IPCC ,2007).

Science established a causal effect between the acceleration of Green House Gas (GHG) emissions and CC effects (IPCC ,2007), Global GHG emissions due to human activities have grown since pre-industrial times, with an increase of 70% between 1970 and 2004.

Among the world’s regions, Arab region is especially

Temperature
Simulated ranges of warming for Arab region are shown in Figure 2, According to (IPCC 2007) report , in the best scenario, By 2030, annual average temperatures are 0.5 to 1.0 °C higher over most of Arab region, By 2070, the increase in annual average temperatures will range from 1 to 1.5 °C , By 2100 , the increase in annual average temperatures is predicted to reach 2.5 to 3.0 °C . Model results indicate that future increases in daily maximum and minimum temperature will be similar to the changes in average temperature.

In the worst scenario By 2030, annual average temperatures are 1 to 1.5 °C higher over most of Arab region, By 2070, the increase in annual average temperatures will range from 2 to 2.5 °C,By 2100 , the increase in annual average temperatures is predicted to reach 3 to 4.0 °C.

Rainfall

According to (IPCC 2007) report, Projected annual average ranges of precipitation tend toward decrease in the Mediterranean region and northern of the Arab peninsula by 10% to 20 %. And also it is expected that precipitation will decrease between 30% and 40 % in Morocco and north of Mauritania. However, an increase in
