On the occasion of NHRI 90th anniversary, Professor Hong-Yuan LEE and Professor Yih-Chi TAN from Taiwan University, and Professor Wen-Chi LAI from Cheng Kung University were invited to deliver academic lectures at NHRI on the morning of October 28. The lectures were about Adaptation and Response Under Climate Change, Experience and Lessons from Natural Disaster Prevention and Management in Taiwan, and Disaster Prevention and Mitigation Strategies for Deep-Seated Landslides and Induced Hazards: A Case Study of the Emergency Response to the Mataian Landslide Dam, respectively. The lectures were presided over by Vice President PAN Junning.

Professor LEE exchanged insights on the causes, impacts, and countermeasures of climate change. He introduced the threats posed by greenhouse gas emissions, such as sea level rising and weather extremes, and elaborated on how response measures, including land planning, low-carbon technologies, ecological engineering, public-private collaboration, data-driven decision-making, low-impact development, public participation, and building resilient cities, were taken for achieving sustainable development.

Professor TAN systematically shared the experiences in early warning and management of natural disasters in Taiwan, covering monitoring and early warning technologies for debris flows, torrential rains, and earthquakes, as well as non-engineering measures, such as disaster-preventive community building and civil prevention volunteer training. During his presentation, he emphasized enhancing overall societal capacity in disaster prevention and mitigation, and emergency response through technological application, public education, and cross-sector collaboration, to establish a resilient disaster prevention system from "self-help and mutual aid" to "public assistance".

Professor LAI, using the Mataian Landslide Dam as a case study, discussed disaster prevention and mitigation strategies for deep-seated landslides in Taiwan. He analyzed the geological types and causes of deep-seated landslides, reviewed current policies and treatment strategies, and stressed the importance of detailed surveys, intelligent monitoring, engineering treatment, and early warning and response systems (such as integrating rainfall data, activity monitoring, and AI technology) to improve slope resilience and disaster prevention capabilities. He also highlighted the role of public-private partnerships and community involvement in building a comprehensive disaster prevention and response system.

Nearly 60 researchers and graduate students attended the lectures and engaged in in-depth exchanges and discussions with the professors on issues related to natural disaster prevention and mitigation strategies.

After the lectures, the professors visited NHRI Tiexinqiao Water Experiment Center and Nanjing Research Institute of Hydrology and Water Conservation Automation, Ministry of Water Resources, P. R. China.
