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?
DRR and SDG
Goal 9: Build Resilient Infrastructure
Goal 11: Make cities and human settlements safe and resilient
Goal 13: Action against climate change and impacts
How space technology and GIS can help?
