碩士 / 國立成功大學 / 海洋科技與事務研究所 / 100 / A large amount of land-based wastes that are not well disposed of inevitably enter into the sea and cause marine debris problem. Costal and ocean activities as well as casual dumping behaviors all exacerbate the severity of the issue. Marine debris may flow worldwide by ocean currents, polluting ocean and some coastal areas. Plastic debris can cause more serious problems due to their degradation time. Many countries have set related regulations to prevent or decelerate oceanic litter pollution by starting monitoring programs and setting management strategies. Nevertheless, Taiwan has yet established related regulation to suit this international trend.
In this study, we conducted a transect survey to investigate the fluctuation of marine litter on four selected beaches in Chijin, Kaohsiung. The patterns of marine litter were analyzed and results were compared with litter survey in the literature. The results were also compared with the land-based waste management practices in Taiwan to evaluate if the current practice has any influences on the characteristics of the beach litter found. For the fishing related wastes that contributed to a large portion of the debris in this study, in-depth interviews were performed with relevant stakeholders to explore their opinions regarding to this issue.
During the survey, we collected a total of 23,264 items of beach litters that weighted 158,345 gm for an average of 0.89 items per square meter. The top three beach litters found were: plastic, Styrofoam, and straw that contributed to 54.6% of beach litter items. By comparing our results of litter characteristics with other country, we observed that waste management strategy regarding to the use of plastic products in Taiwan such as plastic restriction policy and compulsory trash-sorting policy may help in alleviating marine litter problem. Based on the theory of environmental resource governance, the current problem of derelict fishing gear from oyster marine culture may originate from the mismatch between the human management institutions and physical scale of marine debris problem. Hopefully, results from the study can provide related agencies some suggestions in developing marine debris regulations and policies.
