Disasters

• Disasters are mostly natural in nature and Un-managed exposure may impact on vulnerable populations.

• Disasters occur when hazards are interact with the environmental, social, physical and economic vulnerabilities and exposure of population.

Disaster Risk Management

• DRM is not merely protecting social and economic development against what is seen as external events.

• DRM is the way of transforming development to accept and manage risks and strengthen resilience thereby enabling developments are sustainable.

DRR and SDG

• DRR cuts across different aspects and sectors of Development

• DRR has specific role to play in 10 out of 17 SDG

Goal 1: End of poverty: Can we achieve without DRR? How space technology and GIS can help? Is there a way to locate poor? Why they are poor? How disasters impact on poor? What interventions are possible?

Goal 9: Build Resilient Infrastructure

Goal 11: Make cities and human settlements safe and resilient

Goal 13: Action against climate change and impacts
