Scientific support by the BONUS+ projects for the sustainability of the Baltic Sea Region: the case of the HELCOM Baltic Sea Action Plan.

The synthesis of the BONUS+ research is introduced. The HELCOM Baltic Sea Action Plan is examined as a case to illustrate the potentials and challenges in building the science-policy making interface on a macro regional level. The projects address environmental challenges in the Baltic Sea as defined by the Baltic Sea Action Plan, or consider the environmental governance and decision making within the Baltic Sea context in general.
