GES4SEAS is a four-year EU-funded project (Sep 2022 – Aug 2026) aiming to inform and guide marine governance with a view to minimising the pressures and impacts that human activities exert on the health of our marine environment, its biodiversity and the functioning of its ecosystem. The project aims to ensure continued provision of ecosystem services. It develops, tests, demonstrates and upscales an innovative and flexible toolbox relevant to adaptive ecosystem-based management. This supports Good Environmental Status in the context of the Marine Strategy Framework Directive and supports policies at national, European and international levels. GES4SEAS solutions are tested and demonstrated at 11 learning sites, including one in the Caribbean Sea.
