Interdisciplinarity is increasingly used to tackle complex scientific questions and address large societal challenges. At the same time, the evaluation of interdisciplinary research proposals poses a set of problems, ranging from missing common standards and criteria to shortages of peer reviewers with experience in evaluating interdisciplinary research. At its third Symposium, Science Europe and its Scientific Advisory Committee brought together researchers and other experts experienced in interdisciplinarity with high-level representatives from Science Europe’s Member Organisations, who fund and perform such research.

Science Europe advocates using the notion of ‘value’ of research. This is wider than ‘impact’ and reflects the intrinsic value of scientific research and its capacity to generate new knowledge. This statement provides a series of key principles and actions for policy makers and research organisations to help bring forward a new vision of impact assessment.

The Roadmap, approved by the Science Europe General Assembly in November 2013, is Science Europe’s action plan to contribute to the elements of a successful research system. It acts as a framework for voluntary collective activity, providing a long-term strategy for the association. The ‘Priority Action Areas’ are those in which Science Europe members believe that there is a potential to achieve tangible and substantive progress, and where they can add real value by working together.
