The escalating frequency and severity of health emergencies, natural hazards, disasters, and geopolitical crises underscore the critical need for evidence-based approaches to preparedness, response, and recovery. These crises have far-reaching humanitarian impacts, disrupting lives and livelihoods worldwide and necessitating coordinated, timely interventions across local, national, regional, and global levels. In response, UNESCO has partnered with the Committee on Data (CODATA) of the International Science Council (ISC) to explore how the principles of open science, as articulated in the 2021 UNESCO Recommendation on Open Science, can inform the development of effective policies for data collection, analysis, and sharing during crises. This initiative aligns with existing international frameworks and policies, emphasizing the role of open science in fostering resilient and informed responses. As part of this effort, the UNESCO-CODATA Data Policies for Times of Crisis Facilitated by Open Science (DPTC) project has produced practical resources, including a factsheet, a guidance document, and a checklist. These tools, integrated into the UNESCO Open Science Toolkit, are designed to facilitate the implementation of the UNESCO Open Science Recommendation and empower stakeholders to adopt robust data practices for crisis management. This webinar will present key findings from UNESCO’s global consultation on crisis data policies and showcase the resources developed to support open, transparent, and reliable data governance in times of crisis.
