Maritime/Marine Spatial Planning (MSP) underpinned by an ecosystem-based approach as one of the core components of integrated marine management is gaining momentum. In turn, a fully-fledged marine cadastre as an integral part of the MSP is still a future vision. The aim of the paper is to explore the Multipurpose, Multidimensional and Interest-Driven Marine Cadastre (MMIMC) as a concept and the synergistic effects between MSP and MMIMC for advancement of the Blue Economy and sustainable, effective and efficient marine governance through the lens of integrated marine management with an emphasis on the Baltic Sea Region (BSR). This paper emphasizes the conceptual perspective of the interaction between the MMIMC and MSP yet to be operationalized, providing overall documentation of the current state in the BSR regarding MSP and MMIMC and proposing conclusions to be used both at regional and national level. The present study offers added value by structuring knowledge and identifying patterns in the research area. In addition, the paper addresses critical questions and presents proposals to promote and guide further studies. The most important conclusions resulting from the research relate to the importance of the use of MMIMC during the implementation, monitoring, evaluation and adaptation stages of MSP. The research also highlights the need to establish a common framework of a multipurpose, multidimensional and interest-driven marine cadastral system for the countries of the BSR. The research process involved use of monographic, dogmatic, comparative, special analytical, macroscopic examination and logical access control methods.
