Abstract
Open science, especially open data and services, is critical for achieving global goals on sustainable development and disaster risk reduction. Sharing data and collaborating openly can help put science into action. Through selected reports, this paper summarizes the 2023 International Data Week session on 'Open Data and Open Services for Disaster Risk Reduction'. Key highlights identified the importance of advancing global resilience in data preparedness throughout the full cycle of a crisis, robust digital technologies adoption, trustworthy and interoperable data infrastructure implementation, and others. The session also underscored the necessity for community-centered approaches to address data challenges and mitigate the impacts of disasters. Open and coordinated efforts are called for at the local, national, regional, and international levels to depict the crisis data landscape, explore cutting-edge technologies, and co-build robust open science infrastructures that prioritize data interconnectivity, interoperability and intelligibility for open data and open service delivery in times of crisis.
