A group of 35 ecologists, economists, social scientists, and ecosystem-service modelers met to discuss: How can assessments of Ecosystem Services (ES) best translate measures of ecosystem service supply into realized benefits to people. Existing ecosystem service research has tended to focus on the supply side (e.g. floodwater retention), without linking these to realized benefits to people (e.g. reduced damage costs downstream). Such a gap is likely to be limiting the relevance and uptake of ecosystem service assessments in policy and management decisions.
