The Global Facility for Disaster Reduction and Recovery (GFDRR) and the UK Department for International Development's (DFID) competitive Challenge Fund pilots new and innovative approaches to overcoming technical and technological challenges in order to strengthen disaster and climate risk decision-making in developing countries.

To this end, this project is supporting the development of data, products, and approaches to support disaster risk management decision-making and build resilience, including through better information, but also strengthening key steps in moving from information to insight and behaviour change.

Each challenge is focusing on the development of a database with hazard footprints, exposure information and vulnerability models. The viability of the databases will be demonstrated using exposure data for Tanzania and another DFID priority country.


The project is divided into three components. The British Geological Survey leads the development of a data schema and data for a multi-hazard database (Challenge 1) while GEM and University College London lead the development of a global exposure database (Challenge 2) and open vulnerability platform for evaluating risk (Challenge 3) respectively. GEM also contributes to Challenge Fund 1 and 3.

GEM leads Challenge Fund 2 on the development of a global exposure data framework, which includes the physical vulnerability characteristics and exposure taxonomy. The aim is to identify the most important vulnerability characteristics; ways to account for uncertainties in exposure and vulnerability models; type of assets that should be supported by the vulnerability and exposure database; and the most common and useful intensity measure types.

The objective of this project is to develop a Data Exploration Tool to promote the ability of a user to access, understand and use hazard, exposure and vulnerability data stored in a format that follows the data schema developed by the Challenge Fund consortia.

British Geological Survey (BGS)

  • leads the development of a data schema and data for a multi-hazard database (Challenge 1) 

GEM Foundation

  • leads the development of a global exposure database (Challenge 2)
