Global Risk Data Platform
Data use:
The objective of PREVIEW is to provide global information on hazards, vulnerabilities, exposure and disaster risks in support of the implementation of the Hyogo Framework of Action. PREVIEW contains the global risk information produced for the 2009 and 2011 Global Assessment Reports on Disaster Risk Reduction of the United Nations Strategy for Disaster Reduction (UNISDR). This information has been produced by UNEP-GRID, NGI and (list all partners and contributors) and is distributed with their consent.

All datasets on PREVIEW can be available for free for non commercial purpose (governments, international organisations, universities, non-governmental organisations, civil society according to the terms of the following disclaimer.

The development, maintenance and distribution of this information is costly. As such, and in order to ensure it's sustainability and further development, users are invited to make an appropriate voluntary contribution to the UNISDR Trust Fund. All such contributions will be reinvested in the research and development of new and enhanced risk information and in the maintenance of the data platform and will be credited in the Annual Report of UNISDR.
