Session: The Nasty Nexus: Nutrients, Wastewater, and Marine Litter

Date and Time: Monday, 11 March 14:30-15:30

The degradation of the marine environment from land-based pollution remains a high priority on the global development agenda. Along with the scourge of marine plastics, untreated wastewater and nutrient loadings have also been having significant impacts on human and marine ecosystem health. This resulting “nasty nexus” which is an increasingly recognized health risk, warrants the adoption of more integrated ‘circular’ approaches to mitigate multiple types of land-based pollution through more sustainable consumption and production practices. It should be also noted that tackling land-based pollution requires a “source-to-sea” approach. The event will explore the emerging issues on the topic of marine pollution from land, with a focus on the nexus between micro-plastics, wastewater and nutrients management, highlighting innovation in structure-conduct-performance (SCP) approaches that may be scaled-up globally.
