The project MontanAqua is carried out within the framework of the National research program NRP 61 "Sustainable water management" by a team of 13 researchers of geographical institutes of universities of Berne, Fribourg and Lausanne. The main objective of the transdisciplinary study is to develop strategies moving towards more sustainable water resources management in the Crans-Montana-Sierre region (Valais), together with actors involved. The study is based on in-depth evaluation of the impacts of the climate/environmental and socio-economic changes on water resources, and on a detailed survey of water use and of current water management systems at a regional scale (11 communes). This objective is addressed through three main research axes – water resources, water use, and socio-economic structure – on different temporal and spatial scales. The Institute of Geography of UNIL is in charge of the analysis of water uses through the PhD thesis of Mariano Bonriposi. The study is divided in two steps: the analysis of current water uses (2010) and modelling of future water uses (2050). Conclusions of the study are the following: (1) climate change will increase local and temporal shortages (e.g. at the end of Summer); (2) a choice for sustainable regional development is necessary to avoid conflicts in the future; (3) the region should develop a demand management strategy with the establishment of a supra-municipal water management institution, with sufficient legal and financial resources.
