Book excerpt: "Across the globe, a consensus is emerging on the central importance of risk information in disaster risk management. When risks are quantified and the potential impacts of hazards are anticipated, governments, communities, and individuals are able to make more informed decisions. This publication highlights some of the influential efforts—by technical specialists, institutions, and governments around the world—to create and communicate risk information quickly and at low cost, to improve the quality and transparency of risk information, and to enable more local engagement in the production of authoritative risk information than ever before. Case studies spanning 40 countries and contributed by more than 50 institutions showcase emerging best practices, demonstrate how risk assessments are being used to inform disaster risk management and broader development, and highlight lessons learned through these efforts.
