Special Talk - Nexus of Earth observations, natural hazard analysis and risk assessments to impact policymaking (Invited)

Atmospheric, oceanic, and terrestrial (space- and ground-based, remotely sensed, and in situ) data and information collected about our planet and accompanied by data analysis and comprehensive hazard and risk assessments enable decisionmakers around the world to shape effective policies related to disaster risk reduction. To provide the relevant information to policymakers, Earth observations should be open, and data sharing coordinated; research on natural and technological hazards and risks become integrated and interdisciplinary; risk assessment be periodic and policy-oriented; and data-driven knowledge on and assessments of the risks be translated into actionable information. Scientific discoveries, based on Earth observations, data modeling and visualization, integrated into hazard and physical/social vulnerabilities studies and into analyses of exposure to hazard will have an impact on assessments of existing and new risks and provide better understanding of multi-risks associated with concatenated (e.g., an earthquake, tsunami, flooding and/or technological failure) or sequential events (e.g., landslide and tsunami followed by a SAR, cholera, or other diseases). ... mehrThe severity of hazard impacts is growing with increasing vulnerability, exposure, inter-connectivity, and the social complexity as well as with failures in risk reduction, public awareness, and building resilience. To mitigate the impacts, we need to develop holistic, co-produced, interdisciplinary, and convergent research, and to communicate the obtained knowledge for informed decision making in a form of usable scientific messages and proposed political and economic actions with the goal of making the available knowledge be used by policymakers and be useful for the society.
