Space-Based Disaster Management: the Need for International Cooperation, Published 2010, 79 pages. The report briefly describes the significant role played by space technology vis-à-vis major natural disasters, overall shortcomings in the presently available space observations and in early warning/forecasting methods. Further it gives an account of various international initiatives which are providing space-based information and services for monitoring and mitigating different natural disasters. Possible satellite constellations carrying both optical and microwave sensors capable of providing data at frequent intervals as well as those providing measurements required as precursors for earthquakes are indicated. The study makes various recommendations related to virtual satellite constellations, data sharing policy, access to in-situ observations across geographical boundaries, strengthening collaborative efforts in developing early warning methods, augmenting communication networks for ensuring availability of data and value-added products in near real-time and necessary efforts required for capacity building and outreach activities.
