“…Few tools included future projections, socio-economic analysis, and stakeholder engagements [26]. Since that publication, several new GIS-based tools have been introduced, e.g., providing spatial interaction analysis [28][29][30] and cumulative impact assessments [29][30][31][32].…”

“…Bergh et al [28] presented a participatory GIS-approach where they introduced the GIS-based SEAGRID tool applied to coastal aquaculture in Western Norway and elicited spatial interaction scores for all pairs of marine uses and natural areas through stakeholder surveys. Spatial interaction scores provided an overview of whether there are synergies (positive score) or conflicts (negative score) between specific uses of the ocean.…”

This paper introduces the MARCO (MARine CO-existence scenario building) concept for using scenario exploration in stakeholder engagement processes in offshore wind. MARCO builds on spatial analyses using geographic information systems (GIS), and projections over time using system dynamics simulation models. We position the concept within the existing literature on tools for decision support and stakeholder participation, and provide a preliminary status on the spatial baselines, as well as example scenarios for area usage in offshore wind and implications, including risks and co-existence opportunities, on other sectors and nature.

Can pots be an alternative fishing gear to gillnets? A Mediterranean case study

Small-scale coastal fisheries in the Mediterranean often employ gillnets, a widely used gear worldwide. The disadvantages of gillnets in this fishery include high bycatch levels of unwanted species and consequent discards. Moreover, spatial conflict with other gears and dolphin depredation often results in considerable economic loss. Alternative fishing methods are being tested. This study investigated whether, in small-scale fisheries in the Adriatic Sea, pots can ensure sustainable harvest of mantis shrimp (Squilla mantis), a major target demersal species in terms of landings, and possibly replace traditional gillnets. We adopted a multidisciplinary approach to investigate the catch efficiency, biological impact, and socio-economic effects of the two fishing methods. We found different species compositions in gillnet and pot catches. Gillnets yielded a greater number of discarded species of no commercial value, whereas pots caught a greater amount of mantis shrimp. Finally, a profit analysis indicated that pot fishery has the potential to increase profits for the commercial fishing industry. This study suggests that pots provide a more sustainable fishing method, both in terms of revenue and environmental impact.
