| Abstract | Coastal areas are facing many threats from the mainland, which can seriously affect the ecologicalenvironment and the livelihoods of coastal residents. Thus, the identification and estimation ofenvironmental hazards to reduce the risk of environmental incidents due to the developmentprocess have drawn the keen attention of researchers. This study proposed a multiple-criteriadecision-making (MCDM) approach based on the combination of the group bestworst method(GBWM) and geographic information system GIS to analyze the hazards of environmentalincidents due to chemical spills from the mainland. A set of 6 criteria that focused on the potentialoccurrence of environmental incidents related to the chemical was proposed, including chemicaltypes, chemical volume, chemical storage safety, potential incident location, chemical incidentresponse plan, and chemical incident response capacity. The optimal weights of the criteria weredetermined by GBWM. In a case study of the southeastern coastal region in Vietnam, 65 fixedsources of potential environmental incidents related to hazardous chemical use, production, andtrading were investigated and analyzed by the proposed approach, of which 15 sources wereidentified as the potential hazard sources of an environmental incident. These hazard sourceswere categorized into four levels: very high, high, medium, and low, accounting for 20.00%,26.67%, 33.33%, and 20.00%, respectively. This study is expected to support the practitionersand policy enforcers in making decisions related to socioeconomic development, which canminimize the hazard of environmental incidents due to chemical spills from the mainland. |
