The International Day for Disaster Risk Reduction was started in 1989, after a call by the United Nations General Assembly for a day to promote a global culture of risk-awareness and disaster reduction.
October 13 is a day to remind the world that disaster risk is man-made. The goal of the 2021 International day for disaster risk reduction is to provide an advocacy platform to highlight best practices and examples of international cooperation that have a positive impact on the lives of people who live in disaster-prone parts of the world i.e. reducing the numbers of people affected by man-made and natural hazards.
The United Nations Office for Disaster Risk Reduction (UNDRR) has a dedicated website for the day, where you can find out more and join their campaign.
