The interaction of stakeholders is regarded key in modern environmental and spatial planning. Marine/maritime spatial planning (MSP) is an emerging marine policy domain, which is of great interest worldwide. MSP practices are characterized by diverse approaches and a lack of transnational cooperation. Actors with various backgrounds have to identify mismatches and synergies to jointly aim towards coherent and coordinated practices. The ‘Living Q’ is a communication method to make actors aware systematically about their viewpoints in an interactive, communicative and playful environment, while it draws on results of a proceeding ‘Q Methodology’ study. Results from ‘Living Q’ exercises with international expert’s groups from European Sea basins show that the method is capable to foster communication and interaction among actors participating in ‘Living Q’ exercises, while having the potential to generate added value to planning processes by actor interaction in a collaborative setting.
