CLAIM research topic: Evidence on the societal benefits of marine litter reduction turns out to be ‘a drop in the ocean’
The first publication in CLAIM’s research topic in the Frontiers in Marine Science journal, examines the evidence on the societal benefits of marine litter reduction, which are mostly non-market ones, in order to be included in cost benefit analyses required by the EU Marine Strategy Framework Directive.
The authors of the article, who are also CLAIM consortium members Jana Stoever, Katrin Rehdanz and Ikechukwu Charles Okoli of the Institute for Environmental, Resource and Spatial Economics at Kiel University, Kiel, Germany, review the existing empirical evidence and use descriptive statistics to determine its main features.
Photo: Geographical Coverage: Number of studies, by continent. Many studies include several sites, but all of them are located on the same continent. The only exception is Blakemore et al. (2002), which includes study sites in both Europe (Malta, Romania) and Asia (Turkey). It was therefore assigned to both continents. All study sites in Turkey are located on the Asian continent and have been included accordingly.
While comparing the availability of estimates with the requirements for the EU Member states, the researchers discover a significant mismatch between the data available and the information required, which cannot be remedied by transferring benefits. This conclusion stands true for both ex-ante and ex-post evaluations.
In conclusion, the authors point out that the evidence currently available is insufficient to establish country-wide policy implications to the extent required to complete the comprehensive evaluations required by the Directive.
