By mobilizing stakeholders from BLUE4ALL’s 25 information sites and Living Labs, i.e. locations across the Mediterranean Sea, the Baltic Sea and the North-East Atlantic regions where (networks of) MPAs have been established and from which lessons learned can be drawn about success and failure relative to how challenges were tackled, we will co-create robust and replicable social, governance, ecological and environmental tools to meet conservation and/or restoration objectives in socially sustainable and acceptable ways. These science-based tools will be tested in Living Labs, i.e. locations where (networks of) MPAs are in the process of establishment and where these tools can be fed into the ongoing MPA process. The operationalized and tested frameworks will ultimately be generalized into a Blueprint Platform for the co-creation of effective, efficient and resilient (networks of) MPAs. This scheme will separate generically encountered challenges and applied solutions from MPA (network)-specific challenges and solutions and develop guidance in a user-friendly manner to end-users (i.e. MPA (network) managers and authorities). This guidance will take the shape of an interactive web-based Blueprint Platform directing the end-users to those challenges and solutions most applicable to their site(s). User-friendliness and applicability will be maximized by cross-checking the Blueprint Platform development with the actors and stakeholders of the Living Labs throughout the whole process of its development. Knowledge transfer and interaction with stakeholders and society-at-large at local to regional scales will lead to the development of a platform for MPA networking to interact with communities of practice boosting the BLUE4ALL legacy to its ultimate goal to restore our oceans and waters.
