国际减灾日的设立可以追溯到1989年。此前，为促进风险意识及减灾的全球性文化，联大倡议设立一个国际日。现在，每年10月13日举行的国际减灾日纪念活动，旨在赞赏全世界民众和社区为减少遭受灾害风险做出的努力，并提高他们对所面临风险的重要性的认识。

2019年主题继续作为“仙台七项”活动的一部分，以《仙台框架》的七个具体目标为中心。今年将重点关注《仙台框架》的具体目标 (d)：“到2030年，通过提高抗灾能力等办法，大幅减少灾害对重要基础设施的损害以及基础服务包括卫生和教育设施的中断。”

International Day for Disaster Risk Reduction (IDDRR) began 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.

Held every 13 October, the day celebrates how people and communities around the world are reducing their exposure to disasters and raising awareness about the importance of reining in the risks that they face.

The 2019 edition continues as part of the "Sendai Seven" campaign, centred on the seven targets of the Sendai Framework.

This year will focus on Target (d) of the Sendai Framework, reduce disaster damage to critical infrastructure and disruption of basic services.
