This study aims to demonstrate economic valuation of ecosystem services using available data in a pilot study area in Norway. The EU FP7 research project OpenNESS and an ongoing collaboration with Oslo Mu-nicipality made it possible to demonstrate a number of value transfer methods. Value transfer is a rapid assessment approach that uses available studies transferred to a new context. The study outlines a framework for evaluating the information requirements of economic valuation of ecosystem services in different decision contexts. We use the framework to discuss information requirements of economic valuation to support different decision-contexts. Ecosystem services valuation and mapping unmotivated by specific decision context risks being both irrelevant and wasteful.
