The IGU Commission "Mountain Response to Global Change" was constituted in 2008 during the International Geographical Congress at Tunis as a successor of the former Commission "Diversity in Mountain Systems". The continuous existence of an IGU Mountain Commission ever since the founding of the Commission on High-Altitude Geography in 1968 by Carl Troll underlines the relevance of the topic.
The effects of global change are expected to be very pronounced in mountains. At the same time, mountain regions supply mankind with essential resources (e.g. water). Thus, it is vitally important to study the impacts of global change in mountains. The aim of the Commission is to promote international co-operation and dissemination of information amongst geographers working on related issues.
