Abstract

<p> Issues related to climate change in coastal areas have been addressed in a wide variety of academic fields and societies, including meteorology, marine physics, chemistry, biology, ecology, policy science, and economics. However, the efforts and initiatives of each relevant academic field or society are rarely shared because climate change science is so interdisciplinary. Furthermore, climate change issues in coastal areas can be studied from the perspective of current status, future prediction, impacts on natural phenomena and human activities, and mitigation and adaptation measures. However, there have been no studies examining researchers’ priorities in their respective academic fields, or issues for such studies in the future. In the present study, we conducted a survey concerning “Future Challenges to Address Climate Change in Japanese Coastal Areas” involving a variety of the member of academic societies interested in climate change. The results show that the top 10 keywords for future challenges to addressing climate change problems in coastal areas were “air and sea temperature”, “decline in biodiversity”, “sea level rise”, “extreme weather and climate”, “greenhouse gas”, “degradation of ecosystem services”, “typhoons and low pressure”, “decrease in fishery products”, “land loss and coastal erosion”, and “fishery management”. Clearly, the respondents placed a high priority on topics involving natural phenomena and human activities, but a low priority on climate-change countermeasures. This tendency was true both for individual keywords and for all the selected keywords together. The reasons for the keyword selection result are discussed, and the current status, future challenges and prospects in Japan are summarized for the top 10 keywords.</p>
