Andean Wetlands: A Signal of Climate Change (Introduction)
Music to communicate findings of a study which observed signs of ecosystem damage from a unique location.
This music was inspired by a study led by Professor Olivier Dangles Ecosystem sentinels for climate change?(1) The study analysed climate change impact on a previously pristine environment. The features of the ecosystem provide 'signals' that warn us about the devastating effects of climate change.
Along with an increase of extreme weather events, the glacier and snow-covered surfaces significantly reduced between 1984 - 2011. The cover offers a natural buffer, protecting the wetland against the negative effects of the drying-out seasons. Its reduction threatens wildlife habitats and is a concern for the livelihood of residents living within proximity, since the wetlands provide forage for animals and a year-long water supply for the people.
Specific music composition techniques were used to communicate these effects and full details are available within the composers' PhD Thesis Music Composition Techniques for Communicating Scientific Topics and Studies. Techniques are ways in which musical features, such as a melody, are composed. They can help listeners perceive topics, such as climate change as well as aspects related to the scientific study.
The composer extends his gratitude to Olivier Dangles, Professor of Ecology at the University of Montpellier, IRD, for having provided the composer with guidance on the scientific aspects of the study.
