CAS-TWAS Centre of Excellence on Space Technology for Disaster Mitigation (SDIM) is formally established in 2013, jointly sponsored by the Chinese Academy of Sciences (CAS) and The World Academy of Sciences (TWAS), and hosted by the Institute of Remote Sensing and Digital Earth (RADI) of CAS. The goal of the Centre is to conduct much-needed research on disaster mitigation through advanced space technologies, especially space-borne Earth observation technology and provide knowledge transfer in developing countries through joint research, education, training workshop and advisory services. In response to the needs of developing countries in disaster mitigation to tackle the natural and human-induced environmental disaster, SDIM will organize the 3rd International Training Workshop on Space Technology for Disaster Mitigation with the theme of “Earth observations for Disaster Risk Management in Developing Countries: Technical Practice and Scientific Application”. With the objective of providing a scientific and practical guide to the participants from developing countries, the workshop will collect and integrate information on international best practices with the applicants to a number of hazards events, especially for floods, droughts, earthquakes and so on. Experts from various national and international organizations, such as TWAS, UN agencies, ICSU, GEO, etc., will share their experiences with working on disaster mitigation and Earth observation.
