What is DRR concept?

Which of the following is a disaster mitigation strategy?

Examples of mitigation strategies include: hazard specific control activities such as flood levees or bushfire mitigation strategies. design improvements to infrastructure or services. land use planning and design decisions that avoid developments and community infrastructure in areas prone to hazards.

Which of the following disasters is a slow onset disaster?

Slow onset disasters Droughts are relatively slow disasters. Climate change, environmental degradation and desertication are very slow onset events, but can and should be considered as disasters in terms of the damage and disruption to lives that they may or indeed already do create.
