In the INTERREG tradition, projects are developed bottom-up, i.e. they are triggered by the expressions of interest of relevant stakeholders. The advantage of such a way of working is that it responds to the territorial needs of each region in question. However, this bottom-up approach seems to jeopardise the overall coherence of the transnational cooperation programmes. As project ideas are developed independently, INTERREG interventions are addressed in different ways and do not always link to each other. INTERREG programmes feel a strong need to have a systemised aggregated picture of individual project results against the backdrop of territorial evidence (as structures, developments, trends, and perspectives) that is relevant for the respective cooperation area. This information should allow them to better capitalise and communicate the overall added value of project results and to steer project and programme development in a more strategic way. In this context, the INTERREG IVB North West Europe (NWE) Programme has expressed its interest for this targeted analysis.
