CAS-TWAS Centre of Excellence on Space Technology for Disaster Mitigation (SDIM) was formally established in 2013. SDIM is 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), 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.
