3．Introduction to the Lecture

Natural disasters pose a ubiquitous challenge to all nations across the globe. Amidst the accelerating impacts of climate change, the frequency and severity of these disasters are escalating, posing significant hurdles to sustainable development. Space-based Earth observation technology, characterized by its macro-scale, dynamic, long-duration, and global coverage capabilities, has emerged as a pivotal support for global emergency disaster reduction and one of the most active areas of international collaboration. Recently, both the United Nations (UN) and the European Union (EU) have advocated for the utilization of scientific and technological innovations, including Earth observation, to propel humanity's sustainable development trajectory.

Satellite resources, associated applied technologies, and typical application scenarios collectively form the foundational framework for satellite emergency monitoring. This report delves into the influence of natural disasters, satellite resources, monitoring applications, and international cooperation on satellite-based emergency management and disaster reduction since the year 2000, examining these factors from both global and Chinese perspectives. It analyzes the evolution of satellite-based emergency management and disaster reduction through the lens of notable global disaster cases. Lastly, based on the current landscape and in alignment with the Global Goals outlined in the 2030 Agenda for Sustainable Development, the report forecasts the future trajectory of satellite emergency disaster reduction and explores and proposes cutting-edge scientific and technological directions in this field.
