Roundup: Avalanches, Droughts, and Sherpas
Calving Event in Peruvian Lake Damages Infrastructure Designed to Reduce Flood Risk
From El Comercio: “Small ice avalanches have damaged the system of syphons in Lake Palcacocha, Ancash, Peru. Marco Zapata, the head of the Glacier Research Unit at INAIGEM, stated that on May 31, around 8 p.m., a calving event occurred at the glacier front on Mount Pucaranra, releasing ice into the lake. This event generated waves 3 meters in height, which caused 10 of the syphons to shift and which destroyed three gauges and a water level sensor.”

Asian Glaciers Fight Against Drought
From Nature: “The high mountains of Asia… have the highest concentration of glaciers globally, and 800 million people depend in part on meltwater from them. Water stress makes this region vulnerable economically and socially to drought, but glaciers are a uniquely drought-resilient source of water. Glaciers provide summer meltwater to rivers and aquifers that is sufficient for the basic needs of 136 million people… Predicted glacier loss would add considerably to drought-related water stress. Such additional water stress increases the risk of social instability, conflict and sudden, uncontrolled population migrations triggered by water scarcity, which is already associated with the large and rapidly growing populations and hydro-economies of these basins.”

Sherpas Demand Summit Certificates at Protest
From The Himalayan Times: “Hundreds of sherpa climbers who met at Mt Everest base camp [in May] asked the government to immediately issue their summit certificates… Sherpa climbers who made it to the top of several peaks, including Mt Everest, have not been getting their summit certificates since last year after the government refused to approve their ascents citing a clause of the Mountaineering Expedition Regulation that bars them from obtaining such certificates… For most of the foreign climbers, summiting a mountain without sherpas’ help is almost impossible in Nepal… The new amendment to the regulation will recognize high-altitude workers as a part of the expedition to get certificates.”
