AQUACROSS is a Horizon 2020 project which aims to support EU efforts to protect aquatic biodiversity and ensure the provision of aquatic ecosystem services. As such, AQUACROSS seeks to advance knowledge and application of ecosystem-based management for aquatic ecosystems to support the timely achievement of the EU 2020 Biodiversity Strategy targets.
