A large part of activities that require water, particularly irrigation, is dependent on water stocks in dams that are being managed at this moment. Especially in winter we often have Western disturbances that come to water all of Northern Europe and also Morocco, so when we have blocking situations of an anticyclonic type we have no precipitation and the longer these situations persist, the less rain we have arriving. And in fact there is climate change which has two major effects on Morocco in particular, we have both a decline in precipitation over 20-30 years, and at the same time we have a sharp increase in temperatures in this region, these droughts will increase in an almost certain manner.
