This article will deal with National Disaster Management Authority (NDMA) in detail along with Hazards and types of Hazards. We will also see the key authorities in India dealing with Disaster along with their role in brief.
India and its Multi-Hazard Vulnerability— As per the definition adopted by UNISDR, hazard is a dangerous phenomenon, substance, human activity, or condition that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods and services, social and economic disruption, or environmental damage.India, due to its, physiographic and climatic conditions is one of the most disaster-prone areas of the World.

India’s Disaster Vulnerability
- Nearly 59 per cent of the landmass is prone to earthquakes of moderate to very high intensity.
- More than 40 million hectares (12 per cent of land) is prone to floods and river erosion.
- Of the nearly 7,500 km long coastline, close to 5,700 km is prone to cyclones and tsunamis.
- Nearly 68%of the cultivable area is vulnerable to drought.
- Large tracts in hilly regions are at risk from landslides and some are prone to snow avalanches.
- Vulnerability to disasters/emergencies of CBRN origin also exists.
Causes of Disaster
Heightened vulnerabilities to disaster risks in the current time can be related to
- expanding population,
- urbanisation, and industrialisation,
- development within high-risk zones,
- environmental degradation
- climate change.
Besides these various human-induced activities are also responsible for accelerated impact and increase in frequency of disasters in the country like
- increasing demographic pressure,
- deteriorating environmental conditions,
- unscientific development,
- faulty agricultural practices and grazing,
- unplanned urbanisation,
- construction of large dams on river channels
- In the context of human vulnerability to disasters, economically and socially weaker segments of the population are the ones that are most seriously affected.
- Within the vulnerable groups, elderly persons, women, children— especially women rendered destitute, children orphaned by disasters and differently abled persons are exposed to higher risks.
- The DM Act 2005 and National Policy on Disaster Management 2009 for defining the roles and responsibilities.
- consider disasters to be
- Human-induced including CBRN threats (Chemical, Biological, Radiological, and Nuclear (CBRN))
Now let’s Study about Disaster
What is Disaster
The revised terminology of the United Nations Office for Disaster Risk Reduction defines ‘disaster‘ as: “A serious disruption of the functioning of a community or a society at any scale due to hazardous events interacting with conditions of exposure, vulnerability, and capacity, leading to one or more of the following: human, material, economic and environmental losses, and impacts.”
- The effect of the disaster can be immediate and localized but is often widespread, often persisting for long after the event.
- The effect may challenge or overwhelm the capacity of a community or society to cope using the resources immediately and therefore may require assistance from external sources, which could include neighbouring jurisdictions or those at the national or international levels.
- UNISDR considers disaster to be a result of the combination of many factors such as the exposure to hazards, the conditions of vulnerability that are present, and insufficient capacity or measures to reduce or cope with the potential negative consequences.
- Disaster impacts may include loss of life, injuries, disease, and other negative effects on human physical, mental and social well-being, together with damage to property, destruction of assets, loss of services, social and economic disruption, and environmental degradation.
The DM Act 2005 uses the following definition for disaster:
“Disaster” means a catastrophe, mishap, calamity or grave occurrence in any area, arising from natural or manmade causes, or by accident or negligence which results in substantial loss of life or human suffering or damage to, and destruction of, property, or damage to, or degradation of, environment, and is of such a nature or magnitude as to be beyond the coping capacity of the community of the affected area.”
Types of Disasters
- Primarily disasters are triggered by natural hazards or human-induced or result from a combination of both. Human-induced factors can greatly aggravate the adverse impacts of a natural disaster.
- Even at a larger scale, globally, the UN Inter-Governmental Panel on Climate Change (IPCC) has shown that human-induced climate change has significantly increased both the frequency and intensity of extreme weather events.
- While heavy rains, cyclones, or earthquakes are all-natural, the impacts may, and are usually, worsened by many factors related to human activity.
- The extensive industrialisation and urbanisation increase both the probability of human-induced disasters and the extent of potential damage to life and property from both natural and human-induced disasters.
- Human society is also vulnerable to Chemical, Biological, Radiological, and Nuclear (CBRN) threats and events that might escalate to emergencies/ disasters.
Broadly classifying there are two type of Disaster which can be further classified into different cateogories. Natural Disaster & Human Induced Disasters
The widely accepted classification system used by the Disaster Information Management System of DesInventar classifies disasters arising from natural hazards into five major categories and is used globally for the Sendai targets monitoring:
- Geophysical: Geological process or phenomenon that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods and services, social and economic disruption, or environmental damage. Hydro-meteorological factors are important contributors to some of these processes.
- Hydrological: Events caused by deviations in the normal water cycle and/or overflow of bodies of water caused by wind set-up
- Meteorological: Events caused by short-lived/small to mesoscale atmospheric processes (in the spectrum from minutes to days)
- Climatological: Events caused by long-lived micro to macro-scale processes (in the spectrum from intra-seasonal to multi-decadal climate variability)
- Biological: Process or phenomenon of organic origin or conveyed by biological vectors, including exposure to pathogenic micro-organisms, toxins and bioactive substances that may cause loss of life, injury, illness or other health impacts, property damage, loss of livelihoods and services, social and economic disruption, or environmental damage.
Categories of Natural Hazards
movement of earth
|• Landslide following earthquake;
• Urban fires triggered by earthquakes;
• Liquefaction - the transformation of (partially) water-saturated soil from a solid state to a liquid state caused by an earthquake
• Mass movement of earth materials, usually down slopes
• Surface displacement of earthen materials due to ground shaking triggered by earthquakes
|Volcano||• Surface displacement of earthen materials due to ground shaking triggered by volcanic eruptions, a type of geological event near an opening/vent in the Earth's surface including volcanic eruptions of lava, ash, hot vapour, gas, and pyroclastic material.
• Ash fall; Lahar - Hot or cold mixture of earthen material flowing on the slope of a volcano either during or between volcanic eruptions;
• Lava Flow
• Pyroclastic Flow - Extremely hot gases, ash, and other materials of more than 1,000 degrees Celsius that rapidly flow down the flank of a volcano (more than 700 km/h) during an eruption
|Tsunami||Tsunamis are difficult to categorize they are essentially an oceanic process that is manifested as a coastal water-related hazard. A series of waves (with long wavelengths when traveling across the deep ocean) that are generated by a displacement of massive amounts of water through underwater earthquakes, volcanic eruptions or landslides. Tsunami waves travel at very high speed across the ocean but as they begin to reach shallow water they slow down, and the wave grows steeper.
• Wave Action
|• Avalanche, a large mass of loosened earth material, snow, or ice that slides, flows or falls rapidly down a mountainside under the force of gravity
• Coastal Erosion - The temporary or permanent loss of sediments or landmass in coastal margins due to the action of waves, winds, tides, or anthropogenic activities
• Coastal flood - Higher-than-normal water levels along the coast caused by tidal changes or thunderstorms that result in flooding, which can last from days to weeks
• Debris Flow, Mud Flow, Rock Fall - Types of landslides that occur when heavy rain or rapid snow/ice melt send large amounts of vegetation, mud, or rock downslope by gravitational forces
• Flash Flood Hydrological - Heavy or excessive rainfall in a short period of time that produce immediate runoff, creating flooding conditions within minutes or a few hours during or after the rainfall
• Flood Hydrological - A general term for the overflow of water from a stream channel onto normally dry land in the floodplain (riverine flooding), higher-than normal levels along the coast and in lakes or reservoirs (coastal flooding) as well as ponding of water at or near the point where the rain fell (flash floods)
• Wave Action: Wind-generated surface waves that can occur on the surface of any open body of water such as oceans, rivers and lakes, etc. The size of the wave depends on the strength of the wind and the travelled distance (fetch).
|Meteorological||Hazard caused by short-lived, micro- to meso-scale extreme weather and atmospheric conditions that may last for minutes to days||• Cyclone, Storm Surge, Tornado, Convective Storm, Extra-tropical Storm, Wind
• Cold Wave, Derecho
• Extreme Temperature, Fog, Frost, Freeze, Hail,Heat wave
• Lightning, Heavy rain
• Sandstorm, Dust-storm
*Snow, Ice, Winter Storm, Blizzard
|Climatological||Unusual, extreme weather conditions related to long-lived, meso- to macroscale atmospheric processes ranging from intra-seasonal to multi-decadal (long-term) climate variability||• Drought
• Extreme hot/cold conditions
• Forest/Wildfire Fires
• Glacial Lake Outburst Flood (GLOF)
|Biological||Exposure to germs|
and toxic substances
|• Epidemics: viral, bacterial, parasitic, fungal, or prion infections
• Insect infestations
- The National Policy of Disaster Management 2009 notes that the rise in population, rapid urbanization and industrialization, development within high-risk zones, environmental degradation, and climate change aggravates the vulnerabilities to various kinds of disasters.
- Due to inadequate disaster preparedness, communities, and animals are at increased risk from many kinds of human-induced hazards arising from accidents such as–
- industrial, road, air, rail, on river or sea, building collapse, fires, mine flooding, urban flooding, oil spills.
- Hazards due to CBRN threats and events rank very high among the causes that are human-induced acts. Terrorist activities and secondary incidences arising from intentional or non -intentional activities also add to these risks and calls for adequate preparedness and planning.
India’s response to Disasters
Disaster Management Act, 2005
- The Disaster Management Act, 2005 lays down institutional and coordination mechanisms for effective Disaster Management at the national, state, district, and local levels.
- As mandated by this Act, the Government of India created a multi-tiered institutional system consisting of the National Disaster Management Authority (NDMA) headed by the Prime Minister, the State Disaster Management Authorities (SDMA) headed by the respective Chief Ministers, and the District Disaster Management Authorities (DDMA) headed by the District Collectors/ District Magistrate and co-chaired by Chairpersons of the local bodies.
- In each State/ Union Territory (UT), there will be one nodal agency, for coordination of disaster management, which is referred to in the plan as ‘Disaster Management Department‘ (DMD).
- The institutional arrangements have been set up consistent with the paradigm shift from the relief-centric approach of the past to a proactive, holistic and integrated approach for Disaster Risk Reduction by way of strengthening disaster preparedness, mitigation, and emergency response.
National Disaster Management Plan
- The National Disaster Management Plan provides a framework and direction to the government agencies for all phases of the disaster management cycle.
- The NDMP is a “dynamic document” in the sense that it will be periodically improved keeping up with the emerging global best practices and knowledge base in disaster management.
- It is under the provisions of the DM Act 2005, the guidance given in the National Policy on Disaster Management (NPDM) 2009, and the established national practices.
- The NDMP recognizes the need to minimize, if not eliminate, any ambiguity in the responsibility framework. It, therefore, specifies who is responsible for what at different stages of managing disasters.
- It is meant to be implemented in a flexible and scalable manner in all phases of disaster management:
- Mitigation (prevention and risk reduction),
- Recovery (immediate restoration and build-back better).
The overall coordination of disaster management vests with the Ministry of Home Affairs (MHA). The Cabinet Committee on Security (CCS) and the National Crisis Management Committee (NCMC) are the key committees involved in the top-level decision-making regarding disaster management.The National Disaster Management Authority is the agency responsible for the approval of the NDMP and facilitating its implementation.The figure represents merely the institutional pathways for coordination, decision-making and communication for disaster management and does not imply any chain of command.
