Présentation
Water resources in north-eastern Morocco are increasingly under pressure from a growing human demand and a regional drying trend caused by changing climate patterns. Recently, water resources have reached or already fallen below critical limits. The human exploitation of water resources represents the main reason for an alarming decrease of freshwater resources : caused by population growth, high agricultural irrigation water needs, and the recent implementation of a water-intense tourism sector. The lack of appropriate policies to respond to these challenges determines regional vulnerability und puts socio-economic development at risk. The overarching research objective of this thesis is the identification of human and climateinduced rivers for increasing water stress in north-eastern Morocco with a focus on regional tourism development. With particular regard to climate change and to the water-intense regional development plans, it is necessary to analyse how this will influence the near-term water situation and water demand, respectively. The key economic sectors with the highest share of working population are highly waterdependent,thus sufficient water availability represents the basis for socio-economic development. Climate change in the region can aggravate the scarcity situation : precipitation is now the main hydrological variable, as the quality and quantity of groundwater resources has seriously deteriorated and as water efficiency measures and technologies currently are not appropriate to cover increasing demands. Further, this thesis aims to support the development process of improved water management strategies for the facilitation of socio-economic development. By the means of an integrative research approach the vulnerability to increasing water scarcity is empirically investigated. The chosen research design is a vulnerability assessment approach. Vulnerability assessments have emerged over the past decade as appropriate frame of analysis to assess the impact and scope of different drivers causing socio-ecological vulnerability in the context of climate change. The underlying hypothesis is that regional climate change aggravates existing water scarcity in northeastern Morocco, which is currently pressured by an inadequate demand-supply ratio (water deficit situation). From this general aim overarching research questions and issues have emerged and were refined by sub-questions during the process of research. The causes and the extent of vulnerability and the development and governance context of water scarcity are subject to four articles which support the present thesis.
