HADR Missions
HUMANITARIAN ASSISTANCE, DISASTER RELIEF
“Disaster relief is the response to reduce human suffering associated with natural disasters that cause the disruption of normal transportation and
commerce and destroy infrastructure.”
(excerpt from U.S Southern Command’s HADR mission statement)

Humanitarian Assistance and Disaster Relief Overview
Disasters are dynamic and can leave lives, property, and infrastructure at risk to secondary percussions

Humanitarian Assistance and Disaster Relief Overview
Critical first responders and incident managers need to understand and incident within a geographical context
Equally IMPORTANT is updating and sharing critical information as a disaster unfolds
![Page 6: Humanitarian Assistance and Disaster Relief (HADR) · Humanitarian Assistance and Disaster Relief Overview HADR planning for domestic and international agencies is based on 4 areas](https://reader034.vdocument.in/reader034/viewer/2022042802/5f3ce8691c8c8d6ce7537a99/html5/thumbnails/6.jpg)
Risk Mitigation : Individual
• Is a key to National Preparedness• Conduct an assessment of possible risks. Example in Earthquake prone
areas :- Make structural changes such as the installation of a Gas Meter Earthquake Valve- Seismic retrofits of property - Securing of items inside a building to enhance household seismic safety
• All good ideas but has minimal impact on a larger scale
inset: Gas Meter Earthquake Valve inset: Parking Garage Seismic retrofitting

Risk Mitigation : Government
inset: Flood emergency Preparedness maps
inset: Sacramento River Levee
• Flooding- Construct levees/ dikes- Restriction of building in flood
plains
![Page 8: Humanitarian Assistance and Disaster Relief (HADR) · Humanitarian Assistance and Disaster Relief Overview HADR planning for domestic and international agencies is based on 4 areas](https://reader034.vdocument.in/reader034/viewer/2022042802/5f3ce8691c8c8d6ce7537a99/html5/thumbnails/8.jpg)
Risk Mitigation : Government
• Land Slides/ Mudslides- Conduct terrain slope analysis and identify areas of deforestation and re-seed
• Earthquakes- Identify fault lines and possible secondary hazardsEg. Dams, bridges (ie. Auburn Dam, American River, Auburn, CA)
inset: terrain slope analysis map with respect to possible landslide inset: fault lines map of California

Pre-Disaster Preparation
Identification and mapping of areas that are susceptible to :• Wildfires
- Drought conditions
• Flooding- River valley, flood plains, wetlands & marshes
• Landslides- Deforestation, forest burn areas
• Earthquake hazards- Bridges, highway overpass, dams, etc
![Page 10: Humanitarian Assistance and Disaster Relief (HADR) · Humanitarian Assistance and Disaster Relief Overview HADR planning for domestic and international agencies is based on 4 areas](https://reader034.vdocument.in/reader034/viewer/2022042802/5f3ce8691c8c8d6ce7537a99/html5/thumbnails/10.jpg)
Pre-Disaster Preparation
Lesson learnt from USACE Conference 2011
inset: Satellite imagery of Kathmandu, Nepal
What is the most efficient and effective way to transport supplies out from the airport to the affected regions in the event of an earthquake?
![Page 11: Humanitarian Assistance and Disaster Relief (HADR) · Humanitarian Assistance and Disaster Relief Overview HADR planning for domestic and international agencies is based on 4 areas](https://reader034.vdocument.in/reader034/viewer/2022042802/5f3ce8691c8c8d6ce7537a99/html5/thumbnails/11.jpg)
Pre-Disaster Preparation
Identification and mapping areas that are suitable for :- Staging areas for first responders- Helicopter Landing Zone (HLZ) for personnel evacuation and supply distribution- Construction of relief and refugee camps
• Computer models can identify “at-risk” areas for a specific hazard• Combining those results with near real time information updates; GIS mapping tools can
provide decision makers with vital information about populations, infrastructure, and critical facilities in the “at-risk” areas
![Page 12: Humanitarian Assistance and Disaster Relief (HADR) · Humanitarian Assistance and Disaster Relief Overview HADR planning for domestic and international agencies is based on 4 areas](https://reader034.vdocument.in/reader034/viewer/2022042802/5f3ce8691c8c8d6ce7537a99/html5/thumbnails/12.jpg)
Response
“The RESPONSE phase of an emergency may commence with
Search and Rescue but in all cases, the focus will quickly turn to fulfilling the basic humanitarian needs of the
affected population.”
![Page 13: Humanitarian Assistance and Disaster Relief (HADR) · Humanitarian Assistance and Disaster Relief Overview HADR planning for domestic and international agencies is based on 4 areas](https://reader034.vdocument.in/reader034/viewer/2022042802/5f3ce8691c8c8d6ce7537a99/html5/thumbnails/13.jpg)
Response
• The Response can take the shape of a shelter-in-place or an evacuation- A shelter-in-place scenario requires determining the most appropriate
location to stand up a camp and reassessing the ability to supply it during the relief efforts
- In an evacuation scenario, the condition of the roads, highways, bridges must all be determined in order to safely evacuate the affected population

Response
![Page 15: Humanitarian Assistance and Disaster Relief (HADR) · Humanitarian Assistance and Disaster Relief Overview HADR planning for domestic and international agencies is based on 4 areas](https://reader034.vdocument.in/reader034/viewer/2022042802/5f3ce8691c8c8d6ce7537a99/html5/thumbnails/15.jpg)
Recovery
“The RECOVERY phase starts after the immediate threat to human life has
subsided… the REBUILDING.”
Although geospatial analysis tools and techniques can still be used to
monitor that phase such as monitoring the progress of the
rebuilding, it is not as critical to the overall recovery effort as they were
in the Risk Mitigation, Pre Disaster Preparation and Response phase
![Page 16: Humanitarian Assistance and Disaster Relief (HADR) · Humanitarian Assistance and Disaster Relief Overview HADR planning for domestic and international agencies is based on 4 areas](https://reader034.vdocument.in/reader034/viewer/2022042802/5f3ce8691c8c8d6ce7537a99/html5/thumbnails/16.jpg)
Challenges : Human Challenges
