Journal Title: Larhyss Journal - Year 2017, Vol 31, Issue 31
Abstract
In Morocco, drought is the most frequent major risk in history, with negative impacts on the country's environment and economy. The different regions of Morocco have experienced periods of intense droughts in recent decades. They are characterized by a decrease in rain falls and a tendency to increase temperatures. The watershed of Wadi Isly, in the eastern Morocco, is under a semi-arid climate and has been exposed to severe droughts in recent years. The have negative impacts on the agriculture, water resources and immigration from rural areas. The purpose of this study is to characterize the drought in the Isly basin. It is based on the calculation of the standardized precipitation index SPI (Standardized Precipitation Index), which also indicates the severe and lasting nature of the drought in this region of Morocco. This study also aims to discuss the amplifying factors of this phenomenon in this semi-arid environment.
