Savoie ski resorts commit “ecological suicide”

Member of parliament for the Savoie and former minister, Herve Gaymard has accused ski areas in the Savoie of committing “ecological suicide”. Gaymard, former president of the ANENA (National Association for the Study of Snow and Avalanches), says that the valley has to “stop the headlong over development of ski resorts.” The battle is over water and the players include local farmers, permanent residents, ski resorts and the EDF, the Government run electric company. Along with other local representatives he has called “for a global approach to water management”. Already residents of some towns in the area have suffered from water shortages during the winter.

maurienne snow making

The Tarentaise valley faces pressure from all sides. The 300,000 tourist beds for a permanent population of 50,000 consume 18 millions m3 of water with the peak during the winter months when water is frozen in the ground and rivers are dry. Visitor numbers also put pressure on sewage treatment and some resorts have inadequate facilities. Environment group Mountain Wilderness has accused Ste Foy of investing in apartments and snow canons rather than building a much needed treatment works. Added to these pressures are water required for snow-making. The 22 resorts of the Tarentaise valley are rapidly expanding man made snow coverage, last year les Arcs doubled the area served. This has an impact on energy requirements and water usage. It is expected that snow-making in the area will require 8 to 10 million m3 of water by 2015. Paradoxically snow making is most needed when water is in short supply. When there is no insulating coat of snow, water sources in the ground are often frozen and unusable. Although the water used for snow making is eventually returned to the environment it is estimated that up a third evaporates before it reaches the ground. Artificial snow is denser than real snow and melts later in the season. The abnormally warm weather last winter also illustrated the limits to snow making which requires sub-zero temperatures[1]. Hydroelectric generation, another component in running ski resorts also disturbs the water cycle. The EDF has 18 dams, including the major reservoir of Tignes, in the valley.

The EDF also stocks 315 million m3 of water in the Mont Cenis reservoir in the Maurienne. Sufficient to irrigate 150,000 hectares of pasture for a year. Although rainfall was near normal last winter the Savoie has suffered from four dry years which have exhausted out the aquifers. Rainfall has dropped from an average of 700 mm to 500 mm per year. Local farmers have noticed that springs are slow to start at end of winter and have reduced flow rates. The Maurienne gets tax breaks for developing tourism as part of a Rural Revitalisation Zone (Zone de Revitalisation Rurale - Z.R.R.). Tourist beds have increased from 75,000 to 125,000 over the last decade and many resorts are expanding their ski areas and installing snow making. The need for artificial snow is even greater in the Maurienne as many ski runs are low lying. Farmers are concerned about the future. A recent study by the Savoie County Council (conseil général) claims that haymaking capacity has dropped between 3 and 10 times depending on the area. Hay is used to feed the cattle that supply milk for the local Beaufort cheese. A new study will look at water resources in the area. Albert Tourt, vice president of the farmers association say that everything is linked, water is being over exploited and that a charter of best practise needs to be drawn up between the various interests.

The French Secretary of State for Tourism has called on ski resorts to explore new ideas for the mountain. He thinks tourism should take greater account of the environment and rely less on “white gold” - downhill skiing. Speaking to journalists during the opening of a new weather station on the emblematic Aiguille du Midi at Chamonix he said that “what worked in the past will not necessarily work in the 2015-2020 time-frame, we need new ideas… ski resorts need to face up to reality”. Visitor numbers to ski resorts dropped 7.1% during last winter and numbers are down 10-15% this summer due to the difficult climatic conditions. According to Marc Saddier, who represents 250 French ski resorts, the climate warmed 1.5C during the last century and this has raised the snowline by 250 meters. Every extra degree will see the closure of 100 ski resorts, he claims. Last winter saw the closure of Céüze and Abondance and a financial crisis at Transmontage.

Glacier Blanc gains mass

For the first time since 2001 the mass balance of the Glacier Blanc in the Ecrins range is positive. It has gained 21cm (water equivalent) in the last year. However the snout remains very thin and is vulnerable to another hot summer such as that of 2003.
