  3. 3. Projecto Glaciares“Adaptación al cambio climatico y reducción deriesgos y desastres por desglaciación de los nevadosandinos de Cusco y Ancash en Perú“Component 1 (local level): Case studies of the Laguna 513 in the CordilleraBlanca and in the region of Santa Teresa in Cusco (near Machu Picchu) focusingon glacial risks.Component 2 (academic level): Academic capacity building by newdiploma/master courses in glaciology, climate change and high-mountain riskmanagement.Component 3 (institutional level): Strengthening of glaciology in Peru bysupporting key institutions such as UGRH (Unidad de Glaciología y RecursosHídricos) in terms of technologies and methodologies for climate change-relatedglacier and integral high-mountain research and monitoring.
