Blankets covering Swiss glacier to halt ice melt is a temporary fix
“From a distance, the Rhone glacier seems perfect, but when seen closely, the surface is covered with white blankets for slowing down the melting of the rapidly retreating ice. The dusty, white fleece covers a huge area near the glacier’s edge. But there is a Swiss tourist attraction hidden under the blankets. It is a long and winding ice grotto with shiny blue walls and a leaky ceiling that has been carved into the ice here every year since 1870.
While poking at a piece of cloth lying besides the way that leads toward the cave’s opening, David Volken, a glaciologist working with the Swiss environment ministry, said that for the last eight years, they have been covering the ice cave with such blankets to decrease the ice melt.”

A participatory method to enhance the collective ability to adapt to rapid glacier loss: the case of mountain communities in Tajikistan
“A 2010 participatory case study in the Zerafshan Range, Tajikistan, disclosed a local lack of awareness of climate change and its consequences. We present a social learning method based on scenarios and visualization. The process exposed a remarkable potential for comprehensive adaptation, including in water harvesting, choice of crops and livestock, environmental enhancement, skills and conflict management. We recommend the approach as a model to promote local collective adaptive capacity development. The case study revealed high risks of massive out-migration from mountain villages if adaptation starts too late: countries with a high proportion of mountain agriculture might see significant losses of agricultural area, a reduction in food production and an increase in conflicts in areas where immigration occurs.”

Influence of land use and climate change in glacial melt and hydrological process
“Land use and climate change play a significant role in hydrological processes. This study assesses the impact of land use and climate change in a snow and glacier dominated high altitude watershed, located in the southwestern part of Switzerland…. Our study shows a decrease in the summer peak flow and an early start of the melt driven peak flow. The major change observed in this study is the rising period of the hydrograph, i.e. in May and June an early shift is observed in the discharge. Independent analysis from land use change and climate change shows that the peak flow reduction occurs as a result of land use change, but the peak flow together with the timing of peak flow occurrence is also influenced by climatic change. The combined effect suggests a reduction of peak flow and early melt driven streamflow in the future. Information obtained from this study can be useful for water managers, especially for the hydropower based energy production sector in the Rhone watershed.”
