The joint ESA/UNESCO Open Initiative to conserve hundreds of natural and cultural World Heritage sites using Earth observation satellites gets additional backing as the International Astronautical Federation joins the growing number of space entities to pledge support to the project.
The Open Initiative, agreed upon by ESA and UNESCO (United Nations Educational, Scientific and Cultural Organisation) in 2001, involves satellites monitoring UNESCO World Heritage sites as unique and varied as the Great Barrier Reef and the Great Wall of China in order to provide early warnings of conditions that could threaten them, such as natural catastrophes, atmospheric contamination and changes in land use.
The signing of the partnership between the International Astronautical Federation (IAF) and UNESCO took place today at UNESCO headquarters in Paris, France."
