CAS-TWAS Centre of Excellence on Space Technology for Disaster Mitigation (SDIM) was 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 SDIM 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 addition, the close relationships and outreach with TWAS and its Regional Office will also effectively advance its mission.
