  • 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.

    • 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?
