The International Day for Disaster Reduction started in 1989 with the approval by the United Nations General Assembly. The UN General Assembly sees International Day as a way to promote a global culture of disaster reduction, including disaster prevention, mitigation and preparedness.
Originally celebrated on the second Wednesday of October, the UN General Assembly decided in 2009 to designate October 13th as the date to celebrate IDDR.
The International Day for Disaster Reduction is a day to celebrate how people and communities are reducing their risk to disasters and raising awareness about the importance of DRR. It's also a day to encourage every citizen and government to take part in building more disaster resilient communities and nations.
The 2015 theme for the International Day for Disaster Risk Reduction is part of a Step Up initiative started in 2011.
