Abstract

Oil spills are a constant threat to marine ecosystems and coastal communities. One of the critical aspects of oil spill response is the placement of oil booms. The decision of where to place oil booms is complex as it depends on several factors, including the location of the spill, the nature of the coastline and the potential for environmental and economic damage, especially to the local community. In this paper, a not-oriented slack-based data envelopment analysis (NO-SBM-DEA) approach is proposed to evaluate coastal sensitivity to oil spills. The NO-SBM-DEA approach considers the key aspects of coastal sensitivity: geomorphology, socio-economic and environmental aspects. The specifics of all variables are taken into account when calculating an overall performance score so that there is no need to switch between input and output orientation. The proposed approach provides a comprehensive and objective assessment of coastal sensitivity that can guide the placement of oil booms in the event of an oil spill. All data originate from studies carried out within the North Adriatic Incident Response System (NAMIRS) project. The proposed method was also applied to a case study in the northern Adriatic Sea to demonstrate its potential as a valuable tool for global oil spill mitigation efforts worldwide. The method provides an objective and transparent tool for assessing the sensitivity of coastal areas and can help ensure that oil booms are placed in the most effective locations.
