Schematic representation visualizing the main differences between current practices in NNS risk assessment and the framework for evidence mapping proposed here. Building a transparent and searchable database whereby the evidence base is grouped according to the relevance of the geographical area from where the information is reported, the type of publication, study design and impact direction facilitates evaluating the robustness of NNS impact assessments, and makes them more legitimate for policy decisions.
