GAP2’s purpose was to demonstrate the role and value of stakeholder driven science within the context of fisheries’ governance. The work was coordinated by an interdisciplinary team across Europe, with expertise ranging from social science to fisheries management. GAP2 was built upon the success of GAP1, an 18 month project run from 2007 to 2009, also funded by the European Commission’s FP7 programme. Among the many and varied outputs of GAP1 were 15 fisher-science partnerships from across 11 different European countries, which formed the basis of GAP2’s case studies.
