The iD-Lab, the new Deltares interactive data facility, was officially opened by the World Resources Institute (WRI) on 23 March. The iD-Lab is a physical space that gives researchers and policymakers fast access to the most recent data and models (global, regional or local) so they can make the right decisions, for example in research projects or when disasters threaten. Water is a major theme at the WRI. The organisation's philosophy is: 'Most of the world consists of water. However, water systems are under threat around the world.' Deltares and WRI are allies in this area and we are tackling the global challenges together.
