Estonian Shipping Yearbook 2022 has been published. MAREA project partners from Estonian Marine Institute contributed to an article focusing on cultural heritage and its inclusion to the MSP, showcasing work done at MAREA project. Maritime Spatial Planning (MSP) has become an increasingly used tool to manage our seas and oceans and to allocate space for human activities. Estonian maritime spatial plan, that addresses cultural heritage in a fairly balanced way, will be adopted in 2022. The inclusion of tangible cultural heritage in the plan does not pose a problem as it has a specific spatial location. Oftentimes intangible cultural heritage has been left out of this process as it cannot always be explicitly defined in space, an essential input for MSP processes. However, intangible cultural heritage is an important part of history and legacy of regional communities and an essential input for blue economy and tourism. In this article we looked at how and why cultural heritage and especially its intangible forms can be included in the MSP based on an Estonian example.
