| Lecturer1: Taka Hirata (Senior Researcher, NPO Digital Hokkaido) Presentation Title: Think globally, Act locally: Report of participation in the formulation of Tobetsu Town Action Plan for Global Warming Countermeasures Abstract: The United Nations Framework Convention on Climate Change (UNFCCC) was signed by 154 countries at the United Nations Conference on Environment and Development (commonly known as the Earth Summit) held in Rio de Janeiro in 1992, and entered into force in 1994. Japan also participated in the Convention. In 1998, a domestic law called the “Act on Promotion of Global Warming Countermeasures” was established and the “Global Warming Prevention Plan” was approved by the Cabinet. In response, Japanese local governments were required to formulate Action Plans of Local Governments. Local governments are classified into prefectural and municipal governments, and each of them are required to set up Administration Section Plan as well as Public Section Plan. Tobetsu Town in Hokkaido is a small town with a population of 15,252 (as of March 2024) located in the northern Japan, and the Administration Section Plan has already been implemented by FY2022. In FY2023, the Tobetsu Town Office organized the Tobetsu Town Global Warming Action Plan Committee, including the Author as its member, in order to set up the Public Section Plan. In this presentation, situation of global warming countermeasures in Tobetsu Town is first introduced, and how such a small town can contribute to the Climate mitigation on the national and global scales is discussed. |

| Lecturer2: Tomohiro M. NAKAYAMA (Undergraduate student, Earth Surface Process & Land Management Lab, Faculty of Agriculture, Hokkaido University) Presentation Title: Proposal of a monitoring method for glacial lake expansion using ECMWF numerical forecast reanalysis data Abstract: Recently, glaciers are melting fast, and glacial lakes are expanding due to global warming. Glacial Lake Outburst Floods (GLOFs) are occurring around the world, and its measures are necessary. However, there are too many lakes in the world to observe in situ from cost and time perspectives. The mainstream of GLOF measures is observing lakes using satellite images, but it isn’t available to observe based on glacier melting and hydrological processes. In this study, I suggested a monitoring method for glacial lake expansion available in the world using simple analytical methods which can be conducted by using ordinary computers, and ECMWF numerical forecast re-analysis data ERA5-Land. Using this method in Tsho Rolpa Glacial Lake in Nepal Himalaya, we succeeded in calculating the peak period of glacier melting and input water into the lake with high accuracy. |
