The Middle Draa Valley (MDV) is an oasitic region characterized by an arid climate. The local economy is based on agriculture, and also on tourism. Water scarcity and lack of dense vegetation make it an area vulnerable to climatic change. The environmental vulnerability is accelerated by human pressure and by the high poverty rate that is the highest in the country, thus forcing the population to the overexploitation of this oasitic ecosystem. The purpose of this paper is the realization, of a detailed qualitative analysis based on calculations of a representative number of indicators of environmental vulnerability index (EVI) developed by Stockholm Environment Institute (SEI) and mapping additional factors specific of oasitic system that places an impact environmental vulnerability. The results of this study pave the way to classify this region as a vulnerable area to climate change and anthropogenic impacts.
