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.

Platforms in Remote Sensing

In remote sensing, a platform is the physical structure or vehicle that carries a sensor (camera, scanner, radar, etc.) to observe and collect information about the Earth's surface. Platforms are classified mainly by their altitude and mobility : Ground-Based Platforms Definition : Sensors mounted on the Earth's surface or very close to it. Examples : Tripods, towers, ground vehicles, handheld instruments. Applications : Calibration and validation of satellite data Detailed local studies (e.g., soil properties, vegetation health, air quality) Strength : High spatial detail but limited coverage. Airborne Platforms Definition : Sensors carried by aircraft, balloons, or drones (UAVs). Altitude : A few hundred meters to ~20 km. Examples : Airplanes with multispectral scanners UAVs with high-resolution cameras or LiDAR High-altitude balloons (stratospheric platforms) Applications : Local-to-regional mapping ...

Types of Remote Sensing

Remote Sensing means collecting information about the Earth's surface without touching it , usually using satellites, aircraft, or drones . There are different types of remote sensing based on the energy source and the wavelength region used. 🛰️ 1. Active Remote Sensing 📘 Concept: In active remote sensing , the sensor sends out its own energy (like a signal or pulse) to the Earth's surface. The sensor then records the reflected or backscattered energy that comes back from the surface. ⚙️ Key Terminology: Transmitter: sends energy (like a radar pulse or laser beam). Receiver: detects the energy that bounces back. Backscatter: energy that is reflected back to the sensor. 📊 Examples of Active Sensors: RADAR (Radio Detection and Ranging): Uses microwave signals to detect surface roughness, soil moisture, or ocean waves. LiDAR (Light Detection and Ranging): Uses laser light (near-infrared) to measure elevation, vegetation...

Resolution of Sensors in Remote Sensing

Spatial Resolution 🗺️ Definition : The smallest size of an object on the ground that a sensor can detect. Measured as : The size of a pixel on the ground (in meters). Example : Landsat → 30 m (each pixel = 30 × 30 m on Earth). WorldView-3 → 0.31 m (very detailed, you can see cars). Fact : Higher spatial resolution = finer details, but smaller coverage. Spectral Resolution 🌈 Definition : The ability of a sensor to capture information in different parts (bands) of the electromagnetic spectrum . Measured as : The number and width of spectral bands. Types : Panchromatic (1 broad band, e.g., black & white image). Multispectral (several broad bands, e.g., Landsat with 7–13 bands). Hyperspectral (hundreds of very narrow bands, e.g., AVIRIS). Fact : Higher spectral resolution = better identification of materials (e.g., minerals, vegetation types). Radiometric Resolution 📊 Definition : The ability of a sensor to ...

geostationary and sun-synchronous

Orbital characteristics of Remote sensing satellite geostationary and sun-synchronous  Orbits in Remote Sensing Orbit = the path a satellite follows around the Earth. The orbit determines what part of Earth the satellite can see , how often it revisits , and what applications it is good for . Remote sensing satellites mainly use two standard orbits : Geostationary Orbit (GEO) Sun-Synchronous Orbit (SSO)  Geostationary Satellites (GEO) Characteristics Altitude : ~35,786 km above the equator. Period : 24 hours → same as Earth's rotation. Orbit type : Circular, directly above the equator . Appears "stationary" over one fixed point on Earth. Concepts & Terminologies Geosynchronous = orbit period matches Earth's rotation (24h). Geostationary = special type of geosynchronous orbit directly above equator → looks fixed. Continuous coverage : Can monitor the same area all the time. Applications Weather...

Man-Made Disasters

  A man-made disaster (also called a technological disaster or anthropogenic disaster ) is a catastrophic event caused directly or indirectly by human actions , rather than natural processes. These disasters arise due to negligence, error, industrial activity, conflict, or misuse of technology , and often result in loss of life, property damage, and environmental degradation . Terminology: Anthropogenic = originating from human activity. Technological hazard = hazard caused by failure or misuse of technology or industry. 🔹 Conceptual Understanding Man-made disasters are part of the Disaster Management Cycle , which includes: Prevention – avoiding unsafe practices. Mitigation – reducing disaster impact (e.g., safety regulations). Preparedness – training and planning. Response – emergency actions after the disaster. Recovery – long-term rebuilding and policy correction. These disasters are predictable and preventable through strong...
