CLAIM research topic: A cross disciplinary framework for cost-benefit optimisation of marine litter clean up at regional scale

An article published in CLAIM’s research topic in the Frontiers in Marine Science journal, proposes a bridge-building, spatial cost-benefit optimisation framework. This framework allows to prioritise where to apply limited cleanup efforts within a regional spatial network of marine litter sources, using input from the maturing field of marine litter transport modeling.

According to the authors of the article, CLAIM consortium members Asbjørn Christensen, Kostas Tsiaras, Jens Murawski, Yannis Hatzonikolakis, Jun She, Michael St. John, Urmas Lips and Roy Brouwer, determining appropriate amounts of marine litter cleanup is difficult, because of the cross-disciplinary nature of the problem which involves physics, environmental engineering, science, and economics. Their proposal includes ecosystem functioning in relation to variable litter concentrations as well as the potentially non-linear cost-efficiency of cleanup technologies.

The researchers illustrate their framework “pollution Green” in a Baltic and Mediterranean Sea case study, using real data for litter transport and cleanup technology. The presented framework consistently compares and ranks alternatives using physical, economic, technological, and biological data. The research shows that including pollution Green’s functions is crucial for assessing the feasibility of cleanup and determining the best deployment of cleanup investments.
