    Since the 1860s, government departments have been working to secure natural and human habitats threatened by erosion and mountain torrents. Civil engineering and environmental engineering techniques are used. They range from masonry work to grass seeding to reforestation, and this is done from top to bottom.

    In the high mountains, the snow can last for months and the risk of avalanches is permanent. Despite this, mountain dwellers have always adapted to this environment. Grouped together in communities and leading a self-sufficient life, they have used their ingenuity to take advantage of the constraints and subtleties of the terrain by relying on existing natural protections.

Their photographs provide invaluable data for tracking the evolution of the glaciers from the industrial revolution to the 20th century. Today, they are greatly threatened by global warming.
