Recovery and Rehabilitation


Disaster management involves several phases, including mitigation, preparedness, response, recovery, and rehabilitation. Recovery and rehabilitation are post-disaster activities that aim to restore normalcy and improve resilience in affected areas.


1. Recovery

Recovery is the long-term process of rebuilding communities, infrastructure, economy, and social systems after a disaster. It focuses on restoring normalcy while incorporating resilience measures to withstand future disasters.

  1. Short-term Recovery – Immediate efforts within weeks or months to restore essential services (e.g., water, electricity, healthcare, shelter).
  2. Long-term Recovery – Efforts that take months to years, including rebuilding infrastructure, economic revitalization, and mental health support.
  3. Resilience – The ability of a community to recover quickly and adapt to future disasters.
  4. Livelihood Restoration – Providing economic support to affected populations through job creation, skill training, and financial assistance.
  5. Psycho-social Recovery – Addressing trauma, stress, and mental health impacts of disasters.
  6. Infrastructure Reconstruction – Rebuilding damaged roads, bridges, hospitals, and schools.
  7. Economic Recovery – Providing financial aid, loans, and policies to restore businesses and agriculture.

Example

  • 2004 Indian Ocean Tsunami: Long-term recovery efforts included the reconstruction of houses, fishing boats, and economic support for affected communities.
  • 2015 Nepal Earthquake: The government and NGOs provided financial support, rebuilt schools, and restored tourism-dependent economies.

2. Rehabilitation

Rehabilitation is the process of restoring the physical, social, and economic conditions of an affected community to at least pre-disaster levels. It focuses on providing temporary solutions before permanent recovery measures are implemented.

  1. Temporary Housing – Setting up relief shelters or camps for displaced populations.
  2. Medical Rehabilitation – Providing healthcare, prosthetics, and therapy to disaster survivors.
  3. Social Reintegration – Reuniting displaced families and providing psychological counseling.
  4. Environmental Rehabilitation – Restoring ecosystems, clearing debris, and managing waste.
  5. Cash-for-Work Programs – Engaging affected people in rebuilding efforts by providing financial incentives.

Example

  • Hurricane Katrina (2005): Temporary shelters were set up, and medical rehabilitation was provided for injured victims.
  • Uttarakhand Floods (2013): Government agencies set up temporary housing and provided psychological counseling to affected families.

Remote Sensing Technology

Remote sensing is a rapidly evolving geospatial technology used to collect information about the Earth's surface and atmosphere without direct physical contact . It involves detecting and measuring electromagnetic radiation (EMR) reflected or emitted from objects using sensors mounted on satellites, aircraft, or drones. Remote sensing systems are fundamentally classified based on (1) the energy source used for illumination and (2) the region of the electromagnetic spectrum utilized for sensing . 1. Types of Remote Sensing Based on Energy Source Remote sensing systems are commonly categorized according to whether the sensor generates its own energy or relies on naturally available radiation . Passive Remote Sensing Principle: Passive remote sensing relies on natural sources of electromagnetic energy , primarily solar radiation reflected from the Earth's surface or thermal radiation emitted by objects. Operation: Most passive sensors operate during daylight when sunlight is av...

Spectral Signature vs. Spectral Reflectance Curve

Spectral Signature  A spectral signature is the unique pattern in which an object: absorbs energy reflects energy emits energy across different wavelengths of the electromagnetic spectrum. ✔ Key Points Every natural and man-made object on Earth interacts with sunlight differently. These interactions produce a distinct pattern , just like a "fingerprint". Sensors on satellites record these patterns as digital numbers (DN values) . These patterns help to identify and differentiate objects such as vegetation, soil, water, snow, buildings, minerals, etc. ✔ Examples of Spectral Signatures Healthy vegetation → High reflectance in NIR , strong absorption in red Water → Strong absorption in NIR and SWIR , low reflectance Dry soil → Gradual increase in reflectance from visible to NIR Snow → High reflectance in visible , low in SWIR ✔ Why Spectral Signature Matters It allows: Land cover classification Chan...

REMOTE SENSING INDICES

Remote sensing indices are band ratios designed to highlight specific surface features (vegetation, soil, water, urban areas, snow, burned areas, etc.) using the spectral reflectance properties of the Earth's surface. They improve classification accuracy and environmental monitoring. 1. Vegetation Indices NDVI – Normalized Difference Vegetation Index Formula: (NIR – RED) / (NIR + RED) Concept: Vegetation reflects strongly in NIR and absorbs in RED due to chlorophyll. Measures: Vegetation greenness & health Uses: Agriculture, drought monitoring, biomass estimation EVI – Enhanced Vegetation Index Formula: G × (NIR – RED) / (NIR + C1×RED – C2×BLUE + L) Concept: Corrects for soil and atmospheric noise. Measures: Vegetation vigor in dense canopies Uses: Tropical rainforest mapping, high biomass regions GNDVI – Green Normalized Difference Vegetation Index Formula: (NIR – GREEN) / (NIR + GREEN) Concept: Uses Green instead of Red ...

Spatial Entity and Spatial Object

Concepts Spatial Entity : Refers to any real-world feature or phenomenon that exists in a specific location and can be identified in space. This emphasizes the actual physical or conceptual presence of the feature. Spatial Object : Represents the digital or computational representation of a spatial entity within a Geographic Information System (GIS). This includes its geometry (e.g., points, lines, polygons) and associated attributes. Key Distinction : While the terms are often interchangeable, spatial entity tends to focus on the real-world phenomenon, whereas spatial object highlights its representation in GIS. Key Terminologies Geographic Coordinates : Define the location of spatial entities using a coordinate system (e.g., latitude and longitude). Example: A building at 40.748817° N, 73.985428° W . Geometry Types : Point : Represents a single location (e.g., a well or a bus stop). Line : Represents linear features (e.g., roads, rivers). Polyg...

Atmospheric Window

The atmospheric window in remote sensing refers to specific wavelength ranges within the electromagnetic spectrum that can pass through the Earth's atmosphere relatively unimpeded. These windows are crucial for remote sensing applications because they allow us to observe the Earth's surface and atmosphere without significant interference from the atmosphere's constituents. Key facts and concepts about atmospheric windows: Visible and Near-Infrared (VNIR) window: This window encompasses wavelengths from approximately 0. 4 to 1. 0 micrometers. It is ideal for observing vegetation, water bodies, and land cover types. Shortwave Infrared (SWIR) window: This window covers wavelengths from approximately 1. 0 to 3. 0 micrometers. It is particularly useful for detecting minerals, water content, and vegetation health. Mid-Infrared (MIR) window: This window spans wavelengths from approximately 3. 0 to 8. 0 micrometers. It is valuable for identifying various materials, incl...
