Mountain regions provide essential ecosystem goods and services (EGS). Global change however endangers the capacity of mountain ecosystems to provide key services. The ‹Mountland› project is focusing on three case study regions in the Swiss Alps and aims at proposing land-use practices and alternative policy solutions to ensure the provision of EGS under climate and land-use changes. In ‹Mountland› an integrative approach is applied, com-bining methods from agricultural economics and the political and natural sciences to analyse ecosystem functioning from a holistic human-environment system perspective. In this poster paper, I give a short introduction to the project and summarize those results which are based on the socio-economic land-use model ALUAM which provided a platform for the integration of different inter- and transdisciplinary data and knowledge on a common scale.
