Webinar: Cumulative impacts assessment in marine areas: a multi- disciplinary approach supporting adaptive management of the Adriatic Sea
Dates: January 29, 2019 -
Anthropogenic and environmental pressures on coastal and marine ecosystems are increasing in number and intensity as result of political, economic and societal developments. Climate change is likely to further exacerbate the stress experienced by marine systems, triggering alteration on biological, chemical and physical processes and interfering with human activities and the economic uses of the sea. Improving our capacity to model and evaluate the combined effects of multiple stressors, in decisional contexts characterized by high uncertainty linked to natural dynamics difficult to predict, is therefore essential to address a sustainable marine planning and to boost inter sectorial management strategies.
Moving beyond traditional approaches for cumulative impact appraisal, a multi-risk approach, integrating different metrics and scenarios of climate, ocean, bio-geochemical and anthropogenic pressures in an interactive impacts perspective, was developed and tested in the Adriatic Sea case study. Its operative steps were implemented through integrated tools and methods (i.e. GIS-based maps, Multi Criteria Decision Analysis), including the application of Bayesian Belief Networks to evaluate the likelihood of cumulative impacts under multiple ‘what-if’ scenarios.
In this webinar, the author will provide an overview of the methodological approach, as well as the key findings of its application at the case study level, focusing on their potential to support multi-risk scenarios evaluation and to drive sustainable and adaptive maritime spatial planning and management.
