Learning from past disasters
Are you interested in how past disasters are informing DRR planning? Do you wish to find more information on notable disasters?
These collections explore the lessons learned from past disasters, what were the risk drivers, impacts and efforts towards building back better.
Effective disaster risk reduction requires the consideration of not just what has occurred, but of what could occur. Most disasters that could happen have not yet happened.
