In order to ensure that a programme of measures is fit for purpose, i.e. is able to achieve or maintain good environmental status (GES), there is a need to identify, implement and monitor the included measures in a strategic way. Such a strategic approach has to be built on sound knowledge of consequent changes in the state, level of implementation, effectiveness, and socio-economic impacts of the included measures.
This in turn requires access to current, high quality data of sufficient resolution, as well as rigorous and ecologically valid assessment methods, threshold values and analyses. These should be regionally agreed upon and founded on a solid scientific basis to ensure that the required information is reliable and easily accessible to policymakers. Building such an assessment structure is a long-term process, one which, by its nature, needs to be adaptive, as new information and knowledge leads to an improved understanding of the marine environment.
