International capacity-building collaborations have been initiated to observe glaciers and develop action plans in the tropical Andes and Central Asia. A recent study titled “Glacier Monitoring and Capacity Building,” by Nussbaumer et al., highlights the importance of glaciers in the Andes and Central Asia for water management, hydropower planning and natural hazards.
The Andes and Central Asia are among regions with the least amount of glacier observation data. For Central Asia, this was the result of the collapse of the Soviet Union from 1989 to 1991. In the Andes, institutional instability has been a continuous threat to the continuity of its glacier monitoring program. Monitoring glaciers in these regions can help mountain communities regulate their freshwater supply, manage the risks of glacier related hazards such as avalanches, and track declining runoff, all of which will have consequences for their socioeconomic development. Unfortunately, these two regions are also particularly vulnerable to the impacts of climate change.
As one of the seven South American countries that contain the Andes Mountain Range, Peru recently utilized its glacier monitoring capabilities to assess potential flood risks posed by rapidly changing glaciers in the Cordillera Blanca, a smaller mountain range in the Andes.
Samuel Nussbaumer, the study’s lead author and a climate scientist, explained some of the hazards that changing glaciers can cause in Peru to GlacierHub. He explained that since there are “many new lakes emerging from retreating glaciers, ice could avalanche into these lakes,” which can be dangerous for the surrounding community. To reduce disaster risks in mountainous regions, glacier monitoring is crucial.
“If an event happens, and glacier data is already prepared, then the community can assess the risk and determine why the event happened,” continued Nussbaumer.
Another way that monitoring glaciers in these regions can help mountain communities is through freshwater supply regulation. The Cordillera Vilcanota in southern Peru provides water to the densely populated Cusco region. Glacier changes in Cordillera Vilcanota and other former Soviet Union countries in Central Asia, can have drastic consequences on the freshwater supply in mountain communities.
The majority of freshwater on Earth, about 68.7 percent, is held in ice caps and glaciers. The authors argue that data-scarce regions like Central Asia and the Andes must strengthen their glacier monitoring efforts to inform water management. This will help buffer the high and increasing variability of water availability in these regions.
Furthermore, in Central Asia, interest and awareness in rebuilding the scientific, technical, and institutional capacity has risen due to water issues in the region. Declining freshwater runoff is spurring glacier awareness in Central Asia, specifically in Kyrgyzstan.
“Any assessment of future runoff has to rely on sound glacier measurements and meteorological data in order to get reliable results,” Nussbaumer said.
To sustain capacity-building efforts, Nussbaumer et al. recommend strengthening institutional stability and resources throughout both regions. Nussbaumer concludes that “direct glacier measurements (in situ data) are key to achieving contributions to sustainable mountain development.”
Training youth to monitor and research local glaciers in their community could be a helpful approach. By monitoring how local glaciers change and evolve over time, communities in the Andes and Central Asia can strengthen their hazard management and freshwater regulation capacity. Local research capacities could also be improved by minimizing the bureaucratic barriers that block the implementation of glacial research projects.
The World Glacier Monitoring Service (WGMS), which is supported by the United Nations Environment Programme, has a new project called “Capacity Building and Twinning for Climate Observing Systems” (CATCOS). Professor Martin Hoelzle of the University of Fribourg believes that CATCOS can support developing countries, and help them contribute to the international glacier research and monitoring community. CATCOS is working with developing countries like Kyrgyzstan and Uzbekistan so that they may contribute to worldwide glacier data monitoring networks.
Glaciers in the Andes and Central Asia ultimately enhance the resilience of mountain ecosystems through their freshwater provision and hazard management. Monitoring and protecting them benefits local mountain communities throughout Asia and South America.
