GS Paper: GS3-19.Disaster and Disaster Management.

  • How important are vulnerability and risk assessment for pre-disaster management. As an administrator ,what are key areas that you would focus in a disaster management

  • Drought has been recognised as a disaster in view of its party expense, temporal duration, slow onset and lasting effect on various vulnerable sections. With a focus on the September 2010 guidelines from the National disaster management authority, discuss the mechanism for preparedness to deal with the El Nino and La Nina fallouts in India.

  • The frequency of earthquakes appears to have increased in the Indian subcontinent. However, India’s preparedness for mitigating their impact has significant gaps. Discuss various aspects.

  • The frequency of urban floods due to high intensity rainfall is increasing over the years. Discussing the reasons for urban floods. highlight the mechanisms for preparedness to reduce the risk during such events.

  • With reference to National Disaster Management Authority (NDMA) guidelines, discuss the measures to be adopted to mitigate the impact of the recent incidents of cloudbursts in many places of Uttarakhand.

  • On December 2004, tsumani brought havoc on 14 countries including India. Discuss the factors responsible for occurrence of Tsunami and its effects on life and economy. In the light of guidelines of NDMA (2010) describe the mechanisms for preparedness to reduce the risk during such events

  • Describe various measures taken in India for Disaster Risk Reduction (DRR) before and after signing ‘Sendai Framework for DRR (2015-2030)’. How is this framework different from ‘Hyogo Framework for Action, 2005?

    As per UNDRR, Disaster risk reduction is aimed at preventing new and reducing existing disaster risk and managing residual risk, all of which contribute to strengthening resilience and therefore to the achievement of sustainable development.

    Measures Taken in India Before Sendai Framework (Pre-2015)

    Disaster Management Act, 2005 established NDMA, SDMA, DDMAs – India’s first legal-institutional framework for DRR.

    Formation of NDRF (2006) – a specialised, trained, and equipped response force for multi-hazard operations. Played a major role in Uttarakhand floods (2013).

    National Policy on Disaster Management (2009) – Shifted policy from relief to prevention, preparedness, and mitigation.

    National Cyclone Risk Mitigation Project (2011) – World Bank assisted programme for mitigating risks of cyclones in 8 cyclone prone coastal States

    Early Warning Dissemination System (EWDS)

    Cyclone Risk Mitigation Infrastructure (CRMI)

    Technical Assistance for Capacity Building on Disaster Risk Management

    Project Management and Monitoring

    Measures Taken After Adoption of Sendai Framework (Post-2015)

    (Aligned with Sendai’s four priorities: risk knowledge, governance, investment, preparedness & BBB.)

    National Disaster Management Plan (NDMP), 2016 – India’s first national plan fully aligned with Sendai Framework, covering:

    Multi-hazard risk assessment,

    Prevention-mitigation strategies,

    Sector-wise responsibilities (health, housing, power, transport, education),

    Monitoring indicators aligned with Sendai’s seven global targets.

    Multi-Hazard Early Warning System (MHEWS) – integrates satellite, radar, and IoT data via the IMD’s Decision Support System (DSS). Improves accuracy by 20-40%. Apps used are

    MAUSAM: General weather forecasts.

    DAMINI: Lightning alerts.

    MEGHDOOT: Agromet advisories for farmers.

    Nature-Based Solutions – Mangrove restoration (MISHTI), wetland protection (Amrit Dharohar) to reduce cyclone/flood vulnerability.

    Shift in disaster-financing architecture – from earlier response-only funds to separate mitigation funds at national and state level as per recommendations of 15th FC

    Community-Based Disaster Management under Aapda Mitra/Aapda Sakhi.

    GIS-Based Hazard Mapping– Eg- National Landslide Susceptibility Mapping (NLSM 2023) covers all Himalayan states.

    Global Efforts – Launched coalition of disaster disaster resilient infrastructure

    National Landslide Risk Mitigation Programme (NLRMP) –

    Cyclone Preparedness (Odisha Model) – Mass evacuations, cyclone shelters, and resilient infrastructure. Eg- Only 64 deaths in Cyclone Fani (2019).

    City/state-specific Heat Action Plans (HAPs) for heatwave prediction + response + healthcare preparedness. Eg- Ahmedabad HAP cut mortality by 30-40% since 2013.

    Difference between Hyogo and Sendai Frameworks

    The Sendai Framework’s proactive approach is essential for making Bharat a ‘weather-ready and climate-smart’ nation.

    Disaster Specific

  • Disaster preparedness is the first step in any disaster management process. Explain how hazard zonation mapping will help in disaster mitigation in the case of landslides.

    As per UNDRR, disaster preparedness refers to the knowledge and capacities developed by governments, institutions, communities and individuals to effectively anticipate, respond to and recover from disasters.

    Importance of Disaster preparedness

    Reduces Loss of Life and Property – Eg-Zero casualties during Cyclone Biparjoy (2023) due to preparedness.

    Strengthens Community Capacity – Training local communities in early response, evacuation routes, and safe zones, reduces panic and damage. Eg-Aapda Mitra volunteers.

    Enables Early Warning and Timely Decision-Making

    Minimises Economic Disruptions – Preparedness plans protect critical infrastructure like roads, power lines and bridges. (Türkiye earthquake (2021) resulted in a loss of 4% of GDP.)

    Ensures continuity of critical services such as healthcare, transportation, and communication during disasters

    Role of hazard zonation mapping in landslide risk mitigation

    Identifies Risk areas based on geology, slope angle, rainfall, land use and soil type.

    Guides Land-Use Planning and Regulation- Eg-Building restrictions in Munnar and Wayanad based on hazard maps.

    Helps Design Safer Infrastructure – Eg-Stabilisation measures on NH-44 (Uttarakhand-Himachal) based on zonation inputs.

    Mitigation Measures – Eg- slope strengthening, terracing, afforestation, and drainage correction.

    Integrates with Early Warning Systems (EWS) – Hazard zones combined with rainfall thresholds enable real-time warnings.

    Build community resilience – Locals identify unsafe slopes, evacuation routes and shelter locations using simplified maps.

    Resource allocationNational Landslide Risk Mitigation Programme targets mapped hotspots first.

    Assists in Environmental Regulation – Eg- Quarrying, mining, ban in Western Ghats (Madhav gadgil committee recommendation)

    Hazard zonation mapping in India

    National Landslide Susceptibility Mapping (NLSM) by GSI

    National Landslide Inventory created with 80,000+ mapped landslides.

    ISRO “Landslide Atlas of India” (2023).

    State-level LHZ mapping by SDMAs (Kerala, Uttarakhand, Himachal, Sikkim, Meghalaya).

    LiDAR, UAV & DEM-based mapping in critical areas (Joshimath, Munnar, Gangtok, Nilgiris).

    Rainfall threshold modelling (IMD + IITs) integrated with zonation maps for landslide triggers.

    Earthquake Zonation Map of India (Zone II to Zone V) by BIS/IMD.

    Flood Hazard Atlas for 15+ states by CWC-NRSC (ISRO)

    Drought Vulnerability Atlas of India (IMD + NRSC).

    To prevent a catastrophe like the Wayanad Landslide of 2024, engineering as well as nature-based solutions along with early warning systems, and effective land use practices are essential.

  • Vulnerability is an essential element for defining disaster impacts and its threat to people. How and in what ways can vulnerability to disasters be characterized? Discuss different types of vulnerability with reference to disasters.

    As per UNDRR, vulnerability refers to the conditions determined by physical, social, economic and environmental factors or processes which increase the susceptibility of an individual, a community, assets or systems to the impacts of hazards.

    Vulnerability can be characterized as follow

    Exposure to Hazard – Settlements on riverbanks or seismic zones are more vulnerable. Eg- Joshimath (Uttarakhand)

    Adaptive or Coping Capacity – Ability to anticipate, respond, absorb and recover from a disaster. Eg- Access to savings, insurance, early warning systems.

    Socio-economic Conditions – Poverty, marginalisation and inequity increase susceptibility to harm. Eg- Disaster induced migration

    Governance and Institutional Readiness– Eg- Weak building regulation increases earthquake vulnerability.

    Environmental Degradation increases hazard impact. Eg- ‘Day Zero’ in Chennai due to wetland encroachment.

    Social Networks and Support Systems: – Communities with strong social cohesion, community organizations, and support networks are more resilient to respond to and recover from disasters.

    Health status and access to healthcare services influence vulnerability – Eg- Elderly and Children are more vulnerable to post disaster illness

    Types of Vulnerability with Reference to Disasters

    Physical Vulnerability – Related to infrastructure, buildings, land use, and physical exposure. Eg- houses in Zone V are highly earthquake-vulnerable.

    Social Vulnerability – Eg- Women in rehabilitation camps face violence and trafficking

    Economic Vulnerability – Lack of income stability, livelihood diversity, and financial buffers. Eg- Fisherfolk losing boats in cyclones.

    Environmental Vulnerability- Eg- Loss of mangroves in Sundarbans increases storm-surge impacts.

    Institutional Vulnerability – Weak governance, poor enforcement of safety norms, lack of coordination.

    Technological Vulnerability – Risks arising from industrial, nuclear, or infrastructural failures. Eg- Bhopal gas tragedy.

    Geographic Vulnerability – Eg- Himalayan towns exposed to landslides and GLOFs.

    Mapping vulnerabilities, enforcing inclusive governance, and capacity building at grassroot are essential for disaster resilience.

  • Discuss the recent measures initiated in disaster management by the Government of India departing from the earlier reactive approach.

    Earlier Approach (Reactive Model)

    Relief and Response-Focused – limited emphasis on preparedness or mitigation.

    Fragmented Institutional Setup – No single coordinating agency.

    Weak Early Warning Systems – limited forecasting for cyclones, floods, and lightning. Eg – 1999 Odisha Super Cyclone caused 10000 deaths

    Delayed Emergency Response Mechanisms before NDRF creation (2006). Eg- delay in 2001 Bhuj Earthquake response

    Ad hoc Funding – minimal pre-disaster investment.

    Poor Infrastructure Resilience – Buildings, dams, roads lacked disaster-resilient design.

    Low Use of Technology – Eg- lack of glacial lake monitoring, real-time rainfall data, or landslide susceptibility mapping in Himalayas

    Limited Community Preparedness – Citizens were passive recipients of relief; evacuation plans rudimentary. Eg- high fatalities after Uttarakhand Floods

    Recent Measures Highlighting the Shift from Reactive to Proactive Approach

    Legal & Institutional Strengthening – DM Act 2005, NDMA, NDRF, SDMAs, and DDMAs ensure permanent, structured disaster governance.

    Strengthened Early Warning through IMD + ISRO + IITs. Eg- Zero human casualties during Cyclone Biparjoy (2023)

    Integrated Alert System (SACHET) is operationalised in all 36 States and UTs to send disaster alerts through SMS. Over 6,899 crore SMS alerts in more than 19 Indian languages were sent.

    Multi-Hazard Early Warning System (MHEWS) – integrates satellite, radar, and IoT data via the IMD’s Decision Support System (DSS). Improves accuracy by 20-40%. Apps used are

    MAUSAM: General weather forecasts.

    DAMINI: Lightning alerts.

    MEGHDOOT: Agromet advisories for farmers.

    Nature-Based Solutions – Mangrove restoration (MISHTI), wetland protection (Amrit Dharohar) to reduce cyclone/flood vulnerability.

    Shift in disaster-financing architecture – from earlier response-only funds to separate mitigation funds at national and state level as per recommendations of 15th FC

    Community-Based Disaster Management under Aapda Mitra/Aapda Sakhi.

    City/state-specific Heat Action Plans (HAPs) for heatwave prediction + response + healthcare preparedness. Eg- Ahmedabad HAP cut mortality by 30-40% since 2013.

    Cyclone Preparedness (Odisha Model) – Mass evacuations, cyclone shelters, and resilient infrastructure. Eg- Only 64 deaths in Cyclone Fani (2019).

    GIS-Based Hazard Mapping– Eg- National Landslide Susceptibility Mapping (NLSM 2023) covers all Himalayan states.
