Cleaning our rivers and seas – quantitative modelling of water & marine pollution

In collaboration with the Joint Research Centre

Protecting and restoring aquatic ecosystems and water resources is a key priority of the EU Green Deal and EU water and marine policies (Water Framework Directive and Marine Strategy Framework Directive). From inland to coastal waters and seas, European aquatic ecosystems are subject to human-induced pressures, such as pollution, hydrological and morphological alterations, changes in biological composition and overfishing. Nutrients and litter pollution are examples of well-known and new challenges to protect our rivers, lakes and seas, and all the benefits these ecosystems provide to society. Quantitative assessment of freshwater and marine pollution through modelling can contribute to understand the impact of current and future policy measures and can support the policy implementation process. In this session, we will explore how quantitative modelling tools can support the assessment of policy measures to reduce nutrients and litter pollution in Europe. We will consider the connection between freshwater and marine environment and we will discuss the uncertainty of quantitative modelling of sea pollution through the lens of ensemble modelling.
