Identifiering av nyckelaktiviteter som bidrar till flöden av makroplastavfall på kuststräckorna på ön Koh Chang, Thailand

Sustainable development is vital in order for Thailand to continue to develop as in previous years. However, sustainable development cannot be achieved if the amount of macroplastic littering into the oceans does not decrease. In order to facilitate future decision making regarding this issue, this report aims to identify which human activities that contribute the most to the present macroplastic waste items on Thai shorelines. This identification was performed through a simplified material flow analysis based on observations and simple calculations on the island Koh Chang in Ranong. A comparative study was performed on the dissimilar island Koh Larn in Pattaya in order to eliminate any error factors caused by the specific environment on Koh Chang. It was deduced that Grocery Consumption, Fishing and Dining were the Key Activities on the two islands that contributed to the present macroplastic waste. Tourism was also shown to be a great contributor. The study did not find any signs of a current Rate of Accumulation on Koh Chang. However, there were always macroplastic waste items present in the sampling areas which implies that they might pose a threat to the ecosystems. Further research is needed in order to find a suitable solution for this problem.En hållbar utveckling är central för att Thailand ska kunna fortsätta utvecklas på samma sätt som skett de senaste åren. Hållbar utveckling kan dock inte uppnås om mängden makroplaster som hamnar i haven inte minskar. För att underlätta framtida beslutsfattande ämnar denna rapport att identifiera de mänskliga aktiviteter som i störst utsträckning bidrar till de makroplastföremål som går att finna på thailändska kuststräckor. Denna identifiering utfördes genom en simplifierad materialflödesanalys som baserades på observationer och simpla beräkningar på ön Koh Chang i Ranong. En jämförande studie utfördes på den annorlunda ön Koh Larn i Pattaya för att eliminera felfaktorer som kan ha uppstått på grund av Koh Changs specifika förutsättningar. Studien visade att Livsmedelskonsumption, Fiske, och Restaurangbesök var de Nyckelaktiviteter som bidrog till det befintliga makroplastavfallet. Turism visade sig också vara en stor bidragare till makroplastavfall. Studien kunde inte visa på någon Ackumuleringsgrad på Koh Chang. Trots detta fanns alltid makroplastföremål närvarande i provtagningsområdena på Koh Chang, vilket antyder att dessa föremål skulle kunna innebära ett hot mot ekosystemen. Vidare efterforskningar krävs för att hitta en passande lösning på problemet

What happens next? : A survey of the afterlife of innovation contests

Innovation contests are becoming popular instruments for stimulating development of digital services using open data. However, experience indicates that only a limited number of the results developed during these events become viable digital services attracting a significant user base. Hence, an unresolved question is how organizers choose to support the service development process after the contest is concluded. To further deepen our knowledge about the design of digital innovation contests and the support for the processes after the contests are concluded, we conducted a survey of the websites of 33 digital innovation contests

Two decades of research on ocean multi-use : achievements, challenges and the need for transdisciplinarity

This paper offers a comprehensive, analytical, and critically informed overview of the current state of ocean multi-use research. It delves into the origins, trajectory, and driving forces behind this emerging research field, all within the broader context of investigations addressing the management of increasingly diverse and intensifying activities at sea. The Bibliometrix R package is employed to analyze the social, geographical, and conceptual dimensions of multi-use scientific production. The results obtained are then compared to a larger corpus of publications focusing on both multiple-use Marine Protected Areas (MPAs) and Marine Spatial Planning (MSP). Finally, the paper addresses research gaps, with a particular emphasis on the transdisciplinary challenges associated with translating this new marine policy concept into practical implementation and extending its application beyond European seas.QC 20240613</p
