WIKIAlps is a knowledge and information platform for everyone interested in a sustainable, balanced, and shared territorial development in the Alpine Space. The AlpES project partners are currently hard at work writing WIKIAlps articles about the AlpES project and about ecosystem services(ES) and natural capital in the Alpine Space in general. To expand and advance WIKIAlps, we’d like to invite experts on ES in the Alpine Space to contribute their knowledge to the WIKIAlps by improving, discussing or writing articles. Article topics can range from describing a specific ecosystem service to discussing the MAES process, focus on the Alpine Space in general or on a single country or region, offer a social-economic, political or technical perspective, and can be written in one of the five project languages (EN, DE, IT, FR, and SL). In the glossary at WIKIAlps, suggestions for articles can be found (red link), but other contributions are also very welcome. Contributing to WIKIAlps is easy!
