Wal-ES is the walloon (Southern part of Belgium) platform on ecosystem services which aims to develop decision support tools based on this concept. During its one year of funding, Wal-ES set up the foundations for the development of these tools. A conceptual and an assessment frameworks have been created along with a database that contains all the information needed to assess ecosystem services in Wallonia. More information can be founded on the website (unfortunately just in French): http://webserver.wal-es.be/fr/wal-es.html?IDC=5732
