Skip to 0 minutes and 17 seconds Crans-Montana is one of the most arid regions in the Swiss Alps. Sustainable water governance is an important topic here. Our transdisciplinary case focuses on this concern. Let us now investigate the context and the stakeholders that are relevant for our query. For centuries, water has been a crucial issue for the people living in this region, it was the subject of struggles and competition when groups tried to increase their share of water. The problem is less that water would be scarce everywhere than that it occurs in irregular quantities. In fact, in the higher mountains and during some periods of the year, water is abundant. However, there are huge discrepancies between high elevations and the valley bottom.

Skip to 1 minute and 14 seconds In the high mountains, rains are quite common. In the valley, on the other hand, showers are rare. And due to the higher temperature, a lot of water is also evaporating. In the high mountains, precipitation ranges between 2,500 to 4,000 millimetres per year. On the valley bottom, it is at 600 millimetres per year. As a result, the valley bottom and the slopes where people live and work are very dry.

Skip to 1 minute and 50 seconds In other words, water is there but not at the places where it is most needed nor at the times it is required. Consequently, the need for drinking and irrigation water has always been an important concern. Documents from the 14th century report the huge efforts made to divert water from the water-rich mountain areas to the farming villages on the dry slopes. They also describe the measures taken to store the precious good. Today, the increasing water use of diverse stakeholders shapes the water shortage problem. While agriculture lost its economic importance in recent years, farmers still need a lot of water for irrigation, in particular viticulture and livestock production.

Skip to 2 minutes and 49 seconds From the 1960s onwards, sports tourism and population growth fuelled a construction boom that led to a substantial increase of household water consumption. Tourism activities, such as golf and ski,

Skip to 3 minutes and 4 seconds further contributed to the raise in water use: golf courses need to be irrigated, and artificial snow production has become an essential prerequisite for winter tourism.

Skip to 3 minutes and 19 seconds The far biggest water user, however, is hydropower production. About half of the regional water resources are used in order to generate electricity. Last but not least, water is also used by the various ecosystems of the region.

Skip to 3 minutes and 41 seconds In the very recent years, the development of tourism and the energy market underwent substantial changes. Therefore, it is quite difficult to predict how social and economic factors will develop in the next decades. Nevertheless, the question, how water availability will evolve, is a main concern for the people in the region. In late summer, precipitation is generally low, and water demand is high. The glacier Plaine Morte discharges meltwater that is an important resource during this season. Climate change scenarios indicate that it is unsure how long the glacier will still exist and serve as a natural water reservoir. Thus, we face a problem that has two conflicting drivers.

Skip to 4 minutes and 35 seconds On the one hand are the rising water demands, and on the other hand is the insecurity of future water availability and need. Water governance then becomes a crucial issue. In Switzerland, all administrative levels are involved in water governance.

Skip to 4 minutes and 54 seconds There are three: the communes, the cantons, and the confederation. In our transdisciplinary case, the 11 communes covering the area we studied had all their own water management system. These systems included public legislation, private property rights, several hundred ancient water rights going back to the 14th century, and a multitude of formal and informal agreements that are often taken ad hoc. While there were two intercommunal water management organisations and several traditional water user associations, there is no formal institution that unites water governance arrangements of all communes.

Skip to 5 minutes and 43 seconds Summing up, climate change and socioeconomic development might both significantly modify the future water supply and consumption of water. We need to assume that the general water supply in the region will become even scarcer and that its seasonal distribution may change significantly. These circumstances may fuel existing conflicts of interest or create new ones. Thus, water management practises and strategies need to be fundamentally revisited.

Tackling water scarcity – part 2: 
actors and context

Water scarcity has been an issue for people living in the region of Crans-Montana for a long time. The topic includes uneven distribution as well as the increasing water use of stakeholders in the last fifty years. In this video, Flurina Schneider explores actors and the context of the case study.

Due to its topography and the circulation of water, the region Crans-Montana-Sierre is one of the driest areas in Switzerland. In addition, the changes in economy, tourism, and urban development over the last decades intensified water scarcity. These are just some of the cornerstones that help explain the actual situation as well as future prospects.

This video describes the main circumstances and shows, how in recent years more actors increased the water use. Please study also the files attached below to get more information about the terrain, the political responsibilities, and key water use issues. Thus, the challenges of this case become more outlined.
