In accordance with the EU MSP directive all EU coastal member states were required to produce marine spatial plans by 2021. Not all have met this deadline but many are now published and adopted by national governments. A key requirement of the MSP directive is that marine spatial plans follow an ecosystem-based approach and contribute to the achievement of Good Environmental Status for marine ecosystems, as set out in the EU Marine Strategy Framework Directive. Over the last nine months or so, I have been engaged in the evaluation of selected national-level marine spatial plans, with a view to assessing their degree of alignment with EU environmental legislation and policy objectives. This work has been commissioned by environmental NGOs: Birdlife International and the Irish umbrella NGO Sustainable Water Network (SWAN). In the following, I provide an overview of this work with links to the published reports.
