AndesPlus develops and reviews methods that are feasible for producing scientific bases for climate change adaptation projects in mountain regions. Adaptation to climate change has been recognized as an unavoidable measure, and the number of related projects is strongly increasing. However, the information basis is often very limited. AndesPlus aims at closing the gap between data demand and data availability by providing a guideline for the development of scientific bases. The focus of the project is in the Andes, but several methods should be transferable to other mountain regions.
