This webinar intends to mark the International Day for Disaster Risk Reduction 2021, focusing on Northeast Asia regional cooperation for technology application for disaster risk reduction. It will profile good practices and lessons from China, Korea, and Japan to leverage frontier technologies to ensure resilience and mitigate disaster and climate risks. The Sendai Framework for Disaster Risk Reduction 2015-2030 recognizes that science, technology and innovation are critical in accelerating all aspects of disaster risk reduction and calls for cooperation among scientific and technological communities to develop a science-policy interface for effective disaster risk management. This year, the theme of the International Day for Disaster Risk Reduction 2021 is Target F of the Sendai Framework: “Substantially enhance international cooperation to developing countries through adequate and sustainable support to complement their national actions for implementation of the present Framework by 2030.” Accordingly, with the Trilateral Joint Statement on Disaster Management Cooperation of 2019, heads of government agencies for disaster management of China, Japan and Korea reaffirmed “the importance of trilateral cooperation and information-sharing among the three countries and agreed upon the need for focusing on prevention in disaster management.” In this context, opportunities for mutual learning on advanced disaster management systems deployed by the three countries are key, particularly in applying technology and innovation for risk reduction. The exchange of science, technology and innovation in DRR provides an important boost to disaster risk management in developing countries, and frontier technologies are an excellent opportunity to ensure resilience across developed and developing countries. Through this joint webinar with UNDRR Office for Northeast Asia, Trilateral Cooperation Secretariat hopes to address the key lessons and challenges in technology application, along with solutions to accelerate the use of technologies in disaster risk reduction and resilience. Experts will be invited to share practical experiences and examples from across the hazard spectrum of use of technologies such as UAV remote sensing technology for landslides or monitoring the changes of sea ice; real-time earthquake damage estimation system; and use of a single disaster and safety communications network in national disaster management system, as per TCS and UNDRR publication.
