The impacts of future climate change on wheat yields in the Jordan River basin (Briefing 3.5)

Abstract

The impact of future climate change on wheat yields in the Jordan River basin was evaluated. The effects of decreased rainfall (average of 32 mm) for the predicted period were found to be insignificant on wheat yield, whereas the decrease in the stress index (SI) and consequently, the decrease in wheat yields, were found to be significant. Evaporation reduction measures such as screening mesh or mulching on wheat yield is pronounced only during dry years. The effect of mulching on increased drainage water is considerable, but its use is restricted to a limited area size.
