Hazard, vulnerability, capacity and risk; the legal definition of disaster; kinds of disaster and the 1999 High Powered Committee; India's hazard profile; the disaster management cycle and the 2009 Policy; how the 2005 Act came; NDMA, NEC, SDMA, SEC and DDMA; NIDM and nodal ministries; offences and the COVID-19 lockdown; the 2025 amendment.

This chapter is about how a country prepares for, faces and recovers from a disaster. Part 1 builds the vocabulary first, because UPSC likes to test whether a student can tell a hazard from a disaster, and then explains India's hazard profile and the Disaster Management Act, 2005, which created a chain of authorities from the Prime Minister down to the district Collector. Part 2 turns to money, response forces, early warning and the global frameworks. One thread runs through both: a change of mindset from rushing relief after the event to reducing risk before it.

A hazard is an event or condition that can cause harm: a strong earthquake, a cyclone, a cloudburst, a gas leak. vulnerability is how easily people and things are hurt by it, which depends on where they live, what their houses are made of, and their income and access to information. Capacity is the other side of the scale: the skills, resources and institutions a community can draw on. Disaster risk is often summed up as hazard combined with vulnerability, weighed against capacity, and a disaster happens only when the damage goes beyond what the community can handle on its own. Section 2(d) of the Act writes this into law, defining a disaster as "a catastrophe, mishap, calamity or grave occurrence in any area, arising from natural or man made causes, or by accident or negligence" that causes substantial loss of life, suffering, damage to property or harm to the environment and is "beyond the coping capacity of the community of the affected area".

Disasters are grouped in several ways. By origin, natural disasters may be geological (earthquakes, tsunamis, landslides), hydro-meteorological (cyclones, floods, droughts, cloudbursts, heat and cold waves) or biological (epidemics, pest attacks), while human-made disasters include chemical and industrial accidents, nuclear emergencies, fires and transport accidents; the Bhopal gas leak of December 1984 is India's best-known example. By speed, an earthquake strikes in seconds, whereas a drought builds up over months, which is why drought is declared on rainfall, crop and water indicators rather than on a single day. In 1999 the Government of India set up a High Powered Committee on disaster management under J.C. Pant, which listed more than thirty kinds of disaster in five groups: water and climate related, geological, chemical, industrial and nuclear, accident related, and biological.

India is highly exposed because of its geology, its monsoon climate and its dense population. The young Himalaya and the North-East form the most earthquake-prone belt, and the Bhuj earthquake of 26 January 2001 showed that the peninsula is not immune. Floods visit the Ganga and Brahmaputra plains almost every monsoon; the Rashtriya Barh Ayog assessed in 1980 that about 40 million hectares were flood-prone. Bay of Bengal cyclones strike the east coast more often than Arabian Sea storms strike the west, and the Indian Ocean tsunami of 26 December 2004 battered Tamil Nadu, Kerala, Andhra Pradesh, Puducherry and the Andaman and Nicobar Islands. Drought haunts the rainfed interior from Rajasthan to the Deccan. Landslides threaten the Himalaya and the Western Ghats, as the Kedarnath floods of June 2013 and the Wayanad landslides of July 2024 showed. Heat waves, forest fires and urban floods have grown with climate change and unplanned building.

Disaster management is usually drawn as a cycle. Before a disaster come prevention (not letting new risk arise, such as houses on a river bed), mitigation (reducing the impact through earthquake-resistant codes, cyclone shelters or embankments) and preparedness (plans, drills, warning systems, stocked relief and trained responders). During it comes response: rescue, evacuation, medical care, food and shelter. After it comes recovery: rehabilitation of survivors and reconstruction, ideally safer than before. For decades India's effort sat almost wholly in the relief stage. The National Policy on Disaster Management, 2009 states the change plainly: away from a relief-centred approach towards a holistic, proactive one built on prevention, mitigation and preparedness. Odisha shows what this means. The super cyclone of October 1999 killed close to ten thousand people; before Cyclone Phailin in October 2013 the state moved about a million people to safety, and deaths were in the dozens.

Until the late 1990s disaster work in India meant relief. States had relief codes and relief commissioners, money came through a Calamity Relief Fund shaped by Finance Commissions, and the subject sat with the Ministry of Agriculture because drought was the commonest calamity. Three shocks changed this. After the 1999 super cyclone Odisha set up a state disaster mitigation authority; after the 2001 earthquake Gujarat passed the first state disaster management law, in 2003; and the 2004 tsunami exposed the absence of a national system. In 2002 the subject, except drought, had moved to the Ministry of Home Affairs, still the nodal ministry. The NDMA was first created by an executive order in 2005, and Parliament then passed the Disaster Management Act, 2005, which received assent in December 2005, giving the system a legal backbone: authorities at three levels, a plan at every level, a national response force, dedicated funds and penalties.

At the top stands the National Disaster Management Authority, set up under Section 3. The Prime Minister is its chairperson, and it has up to nine other members nominated by the chairperson, one of whom may be made vice-chairperson. The NDMA lays down policies, plans and guidelines, approves the National Plan and the plans of Union ministries, and recommends minimum standards of relief. Beneath it, Section 8 creates the National Executive Committee, chaired by the Union Home Secretary, which coordinates the response and turns the NDMA's policies into action. The National Policy on Disaster Management was approved in 2009, and the first National Disaster Management Plan was released in June 2016 and revised in 2019.

The same pattern repeats in every state. The State Disaster Management Authority (Section 14) is chaired by the Chief Minister and approves the State Plan, while the State Executive Committee (Section 20), chaired by the Chief Secretary, coordinates action. In each district the District Disaster Management Authority (Section 25) is chaired by the Collector, District Magistrate or Deputy Commissioner, with an elected representative of the local authority as co-chairperson; where a Sixth Schedule district council exists, its chief executive member takes that seat. The district authority prepares the district plan and directs local bodies, which must make their own plans. The logic: a disaster is felt first in a village or ward, so the district acts first, the state backs it, and the Centre steps in when a calamity outgrows the state.

Section 42 gives statutory status to the National Institute of Disaster Management, which trains officials and carries out research. Beyond the authorities, the operational lead for each kind of disaster rests with a nodal ministry, while the Ministry of Home Affairs coordinates the whole. Suppose a district faces a severe drought and, in the same year, an epidemic: the drought is handled through the Ministry of Agriculture and Farmers Welfare and the epidemic through the Ministry of Health and Family Welfare. The table below lists the assignments most often tested.

During a disaster the Act gives the authorities sweeping powers. They can order evacuation, requisition buildings and vehicles, and direct any department. Chapter X makes it an offence to obstruct an official or to refuse a lawful direction, punishable with up to one year in prison, or up to two years if the refusal leads to loss of life or imminent danger; it also punishes false claims for relief, misuse of relief material and false alarms that cause panic. Section 72 gives the Act overriding effect over any inconsistent law. These powers were used on an unprecedented scale in March 2020, when the nationwide COVID-19 lockdown was imposed through orders issued under the Act, showing that the broad definition of a disaster can stretch to a pandemic.

Two decades of experience led to the Disaster Management (Amendment) Act, 2025. It hands the drafting of the national and state plans to the NDMA and the State authorities themselves; earlier they only approved plans prepared by the executive committees. It requires national and state disaster databases holding risk assessments, fund allocations and spending. It gives statutory backing to two bodies that had worked under executive orders: the National Crisis Management Committee, chaired by the Cabinet Secretary, and the High Level Committee, chaired by the Union Home Minister, which approves central financial help to states. It also lets states create an Urban Disaster Management Authority, headed by the municipal commissioner, for the state capital and for cities with a municipal corporation.

Put together, Part 1 gives a clear chain of ideas. A hazard turns into a disaster only where vulnerability is high and capacity low, so the cheapest life-saving work is done before the event. After the shocks of 1999, 2001 and 2004, India wrote this into the Disaster Management Act, 2005: authorities headed by the Prime Minister, the Chief Minister and the Collector, executive committees under the Union Home Secretary and the Chief Secretary, nodal ministries, and emergency powers backed by penalties. The 2025 amendment added urban authorities, databases and statutory crisis committees. Money, responders and warnings, which make the structure work, are the subject of Part 2.

Exam traps

• Three different heads: the Prime Minister leads the NDMA, the Union Home Secretary (not the Home Minister) leads the National Executive Committee, and the Chief Secretary leads the State Executive Committee.
• The DDMA is chaired by the Collector; its co-chairperson is an elected representative of the local authority, not the local MP or MLA.
• Drought is the odd one out: when the Home Ministry took over disaster management in 2002, drought stayed with the Ministry of Agriculture and Farmers Welfare.
• The Act's definition of disaster covers human-made causes, accidents and negligence, not only natural events; a pandemic was handled under it in 2020.
• A hazard is not a disaster: it becomes one only when it exceeds the coping capacity of a vulnerable community.
• Gujarat (2003) passed the first state disaster management law; Odisha set up the first state disaster authority after the 1999 super cyclone. Do not swap them.
• Dates: National Policy 2009; first National Disaster Management Plan 2016, revised 2019; the Act received assent in December 2005.
• Under the 2025 amendment the NCMC is chaired by the Cabinet Secretary and the High Level Committee by the Union Home Minister.

Recap

• Risk = hazard combined with vulnerability, weighed against capacity; a disaster exceeds the community's coping capacity (Section 2(d)).
• Disasters are natural (geological, hydro-meteorological, biological) or human-made, sudden or slow-onset; the 1999 High Powered Committee grouped them into five.
• India faces earthquakes (Himalaya, North-East), floods (Ganga-Brahmaputra plains), east-coast cyclones, tsunamis, drought, landslides, heat waves and urban floods.
• The cycle: prevention, mitigation and preparedness before; response during; rehabilitation and reconstruction after. The 2009 Policy shifted India from relief to risk reduction.
• The 1999 super cyclone, the 2001 Gujarat earthquake and the 2004 tsunami led to the Disaster Management Act, 2005.
• NDMA (Prime Minister) and NEC (Union Home Secretary); SDMA (Chief Minister) and SEC (Chief Secretary); DDMA (Collector, with a local elected co-chairperson).
• NIDM under Section 42; nodal ministries for each disaster, with the Home Ministry coordinating and Agriculture leading on drought.
• Chapter X offences, the overriding effect of Section 72, and the use of the Act for the 2020 COVID-19 lockdown.
• The 2025 amendment: authorities draft their own plans, disaster databases, statutory NCMC and High Level Committee, Urban Disaster Management Authorities.
