With an increasingly unpredictable climate and rising numbers of natural disasters, the need for accurate and actionable data for the project of building resilience is growing. In response, the World Bank has launched the Open Data for Resilience Initiative (OpenDRI) Field Guide, a practical manual for governments and other organizations aimed at setting foundational standards for the open source creation and communication of disaster and climate change information. Developed by the Global Facility for Disaster Reduction and Recovery—a World Bank managed partnership—the Guide is a core component of the OpenDRI framework, which builds on the World Bank’s broader Open Data initiative and seeks to improve disaster and climate change resilience. It will ensure streamlined data sharing and collaboration between diverse actors such as government agencies, the private sector, academia and civil society.
