Overview

Disaster Risk Reduction (DRR) is the systematic approach to identifying, assessing, and reducing the risks of disaster. Unlike traditional disaster management that focuses on post-disaster response, DRR aims to minimise vulnerabilities and prevent new risks before disasters strike.

The core philosophy of DRR is simple: it is cheaper and more effective to reduce risk than to respond to disasters. For every dollar invested in DRR, an estimated $7–15 is saved in post-disaster recovery costs.

India, with its diverse hazard profile — earthquakes, floods, cyclones, droughts, landslides — is among the most disaster-prone countries globally. DRR is therefore not just a humanitarian imperative but an economic and developmental necessity.


Evolution of Global DRR Frameworks

FrameworkPeriodKey ConferenceCore Focus
Yokohama Strategy19941st World Conference on Natural Disasters, Yokohama, Japan (May 1994)First international DRR framework; recognised that disasters have root causes linked to socioeconomic vulnerability, not just natural hazards
Hyogo Framework for Action (HFA)2005–20152nd World Conference on Disaster Reduction, Kobe, Hyogo, Japan (January 2005)Introduced 5 priorities for action; focused on building resilience of nations and communities; emphasised institutional strengthening
Sendai Framework for DRR2015–20303rd World Conference on DRR, Sendai, Japan (March 2015)Current global framework; shifted focus from managing disasters to managing risk; 4 priorities and 7 global targets

Key Conceptual Shifts

  • Yokohama (1994): Moved from a purely scientific/technical approach to recognising socioeconomic roots of vulnerability
  • Hyogo (2005): Built institutional frameworks — disaster management authorities, early warning systems, national platforms
  • Sendai (2015): Shifted from disaster management to disaster risk management — understanding risk, preventing new risk creation, reducing existing risk. Also expanded scope to include man-made and biological hazards (not just natural disasters) — a prescient move validated by the COVID-19 pandemic

Key Concepts — Sendai Framework for DRR 2015–2030

The Sendai Framework for Disaster Risk Reduction 2015–2030 is the global blueprint for reducing disaster risk and building resilience adopted by UN member states. It was adopted on 18 March 2015 at the Third UN World Conference on Disaster Risk Reduction, held in Sendai, Miyagi Prefecture, Japan, and subsequently endorsed by the UN General Assembly in June 2015.

The Sendai Framework is the successor to the Hyogo Framework for Action (HFA) 2005–2015, which was adopted at the World Conference on Disaster Reduction held in Kobe, Hyogo, Japan in 2005. Where the HFA focused primarily on disaster response and preparedness, the Sendai Framework fundamentally shifts focus upstream — to understanding and reducing disaster risk before disasters occur.

Goal: "The substantial reduction of disaster risk and losses in lives, livelihoods and health and in the economic, physical, social, cultural and environmental assets of persons, businesses, communities and countries."


Seven Global Targets

The Sendai Framework established seven global targets to be achieved between 2015 and 2030:

TargetDescription
(a) MortalitySubstantially reduce global disaster mortality — lower the average per 100,000 global mortality rate between 2020–2030 vs. 2005–2015
(b) Affected PeopleSubstantially reduce the number of affected people globally — lower the average per 100,000 global figure between 2020–2030 vs. 2005–2015
(c) Economic LossesReduce direct disaster economic loss in relation to global GDP by 2030
(d) Critical InfrastructureSubstantially reduce disaster damage to critical infrastructure and disruption of basic services (including health and education facilities)
(e) National/Local StrategiesSubstantially increase the number of countries with national and local DRR strategies by 2020
(f) International CooperationSubstantially enhance international cooperation to developing countries through adequate and sustainable support for implementing the framework
(g) Early WarningSubstantially increase the availability of and access to multi-hazard early warning systems and disaster risk information and assessments

Target (e) was notably achieved ahead of schedule — over 100 countries had adopted national DRR strategies by 2020.


Four Priorities for Action

The Sendai Framework is structured around four priorities for achieving disaster risk reduction:

PriorityFocus AreaKey Actions
Priority 1Understanding disaster riskRisk assessments, data collection, vulnerability mapping, hazard monitoring, open access to data
Priority 2Strengthening disaster risk governance to manage disaster riskNational and local DRR strategies, institutional frameworks, legislation, cross-sectoral coordination
Priority 3Investing in disaster risk reduction for resiliencePublic and private investment in DRR, structural and non-structural measures, building codes, land use planning
Priority 4Enhancing disaster preparedness for effective response; "Build Back Better" in recovery, rehabilitation and reconstructionEarly warning systems, evacuation planning, stockpiling, post-disaster reconstruction that improves resilience

Priority 1 — Understanding disaster risk: Policies and practices must be based on an understanding of disaster risk in all its dimensions of vulnerability, capacity, exposure of persons and assets, hazard characteristics, and the environment. This knowledge can be used for risk assessment, prevention, mitigation, preparedness, and response.

Priority 2 — Strengthening disaster risk governance: Coherent national and local frameworks of laws, regulations, and public policies are required at national, regional, and global levels.

Priority 3 — Investing in disaster risk reduction for resilience: Includes building codes, flood defences, ecosystem-based DRR, and social protection through both structural and non-structural measures.

Priority 4 — Enhancing disaster preparedness and "Build Back Better": Experience shows that disaster response capacity alone is insufficient. The concept of "Build Back Better" — using recovery as an opportunity to reduce future risk — is a key innovation of the Sendai Framework over its predecessor.

Key Analytical Point for Mains: The Hyogo Framework (2005) focused on disaster management institutions and processes. The Sendai Framework (2015) shifted focus to disaster risk itself — understanding, reducing, and preventing risk. This conceptual shift from managing disasters to managing RISK is the central analytical distinction. The Sendai Framework also expanded scope to include man-made and biological hazards, not just natural disasters — a prescient move validated by the COVID-19 pandemic.


UNDRR — United Nations Office for Disaster Risk Reduction

The United Nations Office for Disaster Risk Reduction (UNDRR) — formerly UNISDR (United Nations International Strategy for Disaster Reduction) — is the custodian of the Sendai Framework. Headquartered in Geneva, UNDRR:

  • Monitors and reports on implementation of the Sendai Framework targets
  • Maintains the Sendai Monitor — the global online platform for tracking target progress
  • Organises the Global Platform for Disaster Risk Reduction (biennial)
  • Runs the Sendai Seven Campaign — thematic campaigns aligned to each of the seven targets

Build Back Better (BBB)

Build Back Better is a core principle embedded in Priority 4 of the Sendai Framework. It mandates that post-disaster reconstruction should not merely restore the status quo but improve resilience against future disasters.

Principles of BBB

  • Reconstruct infrastructure to higher standards than pre-disaster levels
  • Integrate climate projections into reconstruction design
  • Use the recovery window to implement land use reforms (e.g., relocating settlements from flood plains)
  • Strengthen building codes and ensure compliance during reconstruction
  • Community participation in reconstruction planning

Indian Examples

DisasterBBB Approach
Gujarat Earthquake (2001)Seismic-resistant reconstruction; Gujarat became a model for earthquake-resilient building practices
Kerala Floods (2018)Rebuild Kerala Initiative — integrated climate-resilient reconstruction; river management reforms
Cyclone Fani (2019)Odisha rebuilt damaged cyclone shelters to improved standards; strengthened coastal infrastructure

India's Implementation

National Disaster Management Plan (NDMP)

India's National Disaster Management Plan (NDMP), first released in May 2016, was the world's first national plan explicitly aligned with the Sendai Framework. It was revised in 2019 to incorporate lessons from disasters and update the implementation roadmap through 2030.

The NDMP is structured around the four Sendai priorities and maps specific actions against each target — covering floods, cyclones, earthquakes, landslides, droughts, and industrial/chemical disasters.

NDMA's Role

The National Disaster Management Authority (NDMA), constituted under the Disaster Management Act 2005, is the apex body for disaster management in India. It:

  • Issues guidelines and standards for DRR
  • Coordinates with State Disaster Management Authorities (SDMAs)
  • Contributes India's Sendai Monitor reports to UNDRR

Coalition for Disaster Resilient Infrastructure (CDRI)

India's most significant global contribution to DRR diplomacy:

FeatureDetail
LaunchUN Climate Action Summit, 23 September 2019, New York
Launched byPrime Minister Narendra Modi — India-led initiative
HeadquartersNew Delhi (IIPA Campus, Indraprastha Estate)
StatusInternational Organisation — recognised by Government of India (2022)
Members53 countries and 12 partner organizations (as of 2026)
FocusIntegrating disaster and climate resilience into infrastructure planning, design, and operation

CDRI Key Initiatives

  • Infrastructure Resilience Accelerator Fund (IRAF): Provides technical assistance and capacity building to developing countries
  • Infrastructure for Resilient Island States (IRIS): Launched at COP26 (Glasgow, 2021) by PM Modi — focuses on Small Island Developing States (SIDS)
  • Knowledge partnerships with UNDRR, World Bank, UNDP, ADB, and other multilateral institutions
  • Global Infrastructure Resilience Report: Flagship publication assessing infrastructure vulnerability worldwide

Exam Tip: Cite CDRI whenever writing about India's international leadership in disaster management, climate action, or infrastructure development. It is a versatile example that works across multiple GS3 dimensions — India's multilateral leadership (like ISA), climate diplomacy, and South-South cooperation.

The Odisha Model — A Global Best Practice in DRR

Odisha's transformation in cyclone preparedness is the single most powerful case study for UPSC Mains on DRR effectiveness.

The Transformation Timeline

EventYearDeathsKey Details
Super Cyclone1999~10,000+No cyclone shelters, no early warning dissemination, no evacuation protocol; catastrophic loss
Cyclone Phailin2013~44550,000+ evacuated; improved early warning and shelters (official RDNA figure: 44 deaths)
Cyclone Fani201964Extremely Severe Cyclonic Storm; 1.2 million people evacuated in 48 hours
Cyclone Yaas20213 (in Odisha)Effective early warning compliance; minimal casualties

What Changed — Key Factors

  1. Odisha State Disaster Management Authority (OSDMA): Established after 1999, became a model institution
  2. Cyclone shelter infrastructure: Hundreds of multi-purpose cyclone shelters built along the coast
  3. Community volunteers: Trained village-level volunteers for last-mile warning dissemination
  4. Mock drills: Regular evacuation mock drills in vulnerable coastal communities
  5. Early warning compliance: Strict enforcement of evacuation orders with community trust
  6. Technology integration: Doppler radar, satellite monitoring, SMS/mobile-based alerts

Recognised by UNDRR as a global best practice in cyclone preparedness. The World Bank has also documented Odisha's transformation as a model for other disaster-prone regions.

How to Use in Mains: Odisha demonstrates that DRR investment delivers measurable results. In 1999, Odisha had no cyclone shelters, no early warning dissemination, no evacuation protocol — over 10,000 died. By 2019 (Cyclone Fani), the state evacuated 1.2 million people in 48 hours with 64 deaths. Always cite specific numbers — they make your answer evidence-based and compelling.


Climate Change & Disaster Risk

Climate change is a "risk multiplier" — it increases the frequency, intensity, and unpredictability of extreme weather events.

India-Specific Climate-Disaster Nexus

Climate ImpactDisaster RiskAffected Regions
Increasing sea surface temperaturesMore intense cyclones (rapid intensification events)East and west coasts
Erratic monsoon patternsBoth floods and droughts in same seasonPan-India
Glacial retreatGlacial Lake Outburst Floods (GLOFs)Himalayan states (Uttarakhand, Sikkim, Himachal Pradesh)
Rising sea levelsCoastal flooding, saltwater intrusionLow-lying coastal areas, island territories
Urban heat islandsIntensified heat wavesMajor cities — Delhi, Mumbai, Hyderabad
Changing precipitationCloudburst events, flash floodsHimalayan region, Western Ghats

Policy Linkages

  • NAPCC (National Action Plan on Climate Change): Has indirect DRR components — National Water Mission, National Mission for Sustaining the Himalayan Ecosystem
  • NDC (Nationally Determined Contributions): India's climate commitments include adaptation measures with DRR overlap
  • CDRI: Bridges climate adaptation and disaster resilience for infrastructure
  • Need for climate-smart disaster management — incorporating climate projections into hazard assessment and planning

Vulnerability Mapping & Risk Assessment

Effective DRR depends on knowing where the risks are before disasters strike.

InitiativeAgencyPurpose
National Database for Emergency Management (NDEM)ISRO/NRSCMulti-scale geospatial database for disaster management; hazard/risk zonation mapping
Seismic MicrozonationGSI, NDMADetailed earthquake risk mapping for cities — identifies vulnerable pockets within seismic zones
Landslide Susceptibility MappingGSIMaps landslide-prone areas in Western Ghats, Himalayas, and North-East
Flood Hazard AtlasCWCMaps flood-prone areas along major river basins
Multi-Hazard Vulnerability MappingISRO, NDMACombines multiple hazard layers for comprehensive risk picture

Rapid urbanisation is increasing disaster vulnerability — unplanned construction in flood plains, seismic zones, and landslide-prone areas. Microzonation data must inform building permissions and land use planning. The Smart Cities Mission should integrate multi-hazard vulnerability assessments for risk-informed urban development.


Linkages with SDGs and Paris Agreement

The Sendai Framework is one of three post-2015 global frameworks — along with the 2030 Agenda for Sustainable Development (SDGs) and the Paris Agreement on Climate Change — adopted in the same year.

FrameworkFocusLinkage with Sendai
SDGs 2030Sustainable development (17 Goals)SDG 1 (poverty), SDG 11 (resilient cities), SDG 13 (climate action) directly embed DRR
Paris Agreement 2015Climate change mitigation and adaptationClimate change amplifies disaster risk — DRR and climate adaptation must be integrated
Sendai Framework 2015Disaster risk reductionProvides the specific DRR architecture for SDG and Paris implementation

The Sendai Seven Campaign promotes disaster-resilient communities by building awareness around each of the seven targets through thematic years and country commitments.

Recent Developments (2024–2026)

Sendai Framework Mid-Term Review — 2023 Findings Impacting 2024–2030 Strategy

The Sendai Framework for DRR Mid-Term Review (MTR) was completed in May 2023 (High-Level Meeting: 17–19 May 2023). The MTR found that progress was recorded on only 2 of the 7 global targets — the international community is not on track to achieve the Sendai Framework's expected outcome by 2030. The number of disaster-affected people (Target B) has worsened globally, rising 71% compared to the 2005–2014 baseline. On Target (c) — reducing direct economic losses — only a limited number of countries are on track (variously estimated at 35 in earlier UNDRR data).

India's progress report noted improvements in early warning systems (IMD now provides 5-day cyclone forecasts), reduction in mortality from cyclones, and PM's 10-Point DRR agenda as positive indicators. However, disaster economic losses as a share of GDP have not declined — India's annual economic losses from disasters average approximately 0.5% of GDP (significantly above the global average of 0.3%). The MTR called for integrating DRR into climate adaptation plans, national budgets, and development planning — areas where India needs to strengthen institutional linkages.

UPSC angle: Prelims — Sendai Framework Mid-Term Review 2023; only 35 countries on track for Target C; global disaster-affected people +71%. Mains (GS3) — India's DRR progress assessment; mainstreaming disaster risk in development planning; climate-DRR integration.


CDRI — Coalition for Disaster Resilient Infrastructure Progress (2024)

The Coalition for Disaster Resilient Infrastructure (CDRI) — founded at UN Climate Action Summit 2019 by India — has 53 member countries and 12 partner organisations (as of 2025), covering over 75% of global GDP. CDRI is expanding towards a target of 75 countries and 25 organisations by 2026 (CDRI.world). CDRI's InfraRisk analytical platform was operationalised in 2023, providing countries with risk quantification for infrastructure assets. India is the Permanent Co-chair of CDRI and chairs the CDRI Governing Council.

In 2024, CDRI launched the Small Island Developing States (SIDS) programme — funded by India, with CDRI Secretariat in New Delhi — to help Pacific and Caribbean island nations build disaster-resilient infrastructure. India allocated USD 15 million to CDRI for the SIDS programme. The DRR Technology Bank under Sendai's Priority 3 (Investing in DRR) links with CDRI's work on infrastructure resilience.

UPSC angle: Prelims — CDRI: founded 2019; 43 member countries (2024); InfraRisk platform; SIDS programme. Mains (GS3/IR) — India's global DRR leadership; "Build Back Better" operationalised through CDRI; climate-infrastructure resilience nexus.


India's National Disaster Management Plan (NDMP) 2019 — 2024 Review

India's NDMP 2019 has been under review to align with the post-MTR Sendai Framework priorities and India's NDC 2022. As of May 2026, a formally revised NDMP has not yet been released — the NDMP 2019 remains the operative national plan. The anticipated revision (discussed since 2023) is expected to incorporate compound disaster scenarios (heatwave + drought + water scarcity; GLOF + flash floods + landslide cascades), mainstream DRR into state development plans, and set quantitative targets aligned to India's specific risk profile.

Critically, the Disaster Management (Amendment) Act, 2025 (Presidential assent 29 March 2025; in force 9 April 2025) has transformed the institutional framework: NDMA is now empowered to prepare the National Disaster Management Plan directly; Urban Disaster Management Authorities (UDMAs) are enabled for cities with Municipal Corporations; States can constitute their own SDRFs; and a national disaster database is mandated. This structural reform partially addresses the enforcement gap between Sendai commitments and institutional reality.

India's disaster financing gap — the difference between actual disaster losses and insured/government-covered losses — remains large. Only approximately 8% of India's economic disaster losses are insured (compared to 40% in advanced economies). The 16th Finance Commission (2026-31) has recommended ₹2,04,401 crore for SDRF+SDMF and ₹79,406 crore for NDRF+NDMF — a significant increase — and has further recommended notifying heatwaves and lightning as national disasters (GoI has not accepted this as of May 2026).

UPSC angle: Prelims — NDMP 2019; NDMA as apex body; Sendai's 7 targets. Mains (GS3) — National-international alignment in DRR policy; financing gap; insurance as DRR tool.



Vocabulary

Preparedness

  • Pronunciation: /pɹɪˈpɛəd.nəs/ (BrE) · /pɹɪˈpɛɹd.nəs/ (AmE)
  • Definition: The state of readiness to respond effectively to a disaster or emergency, achieved through advance planning, training, resource stockpiling, early warning systems, and regular drills.
  • Root: Latin praeparāre = to make ready beforehand; prae- = before; parāre = to make ready; -ness suffix
  • Origin: From English prepared + -ness; prepared from Latin praeparāre ("to make ready beforehand"), from prae- ("before") + parāre ("to make ready"); the noun first attested in English in the 1590s.
  • Part of Speech: noun (abstract, uncountable)
  • Word Family: prepare (v), prepared (adj), preparation (n), preparatory (adj), unprepared (adj)
  • Usage: India's experience with successive cyclones demonstrates that institutional preparedness — early-warning systems, pre-positioned relief, and well-rehearsed evacuation protocols under the NDMA — saves far more lives than reactive relief disbursed after a disaster strikes.
  • Synonyms: readiness, preparation, alertness, vigilance, fitness, mobilisation
  • Antonyms: unpreparedness, unreadiness, complacency, negligence
  • Mnemonic: Break it down: "PREPARED + ness" — from Latin prae- ('before') + parare ('to make ready'). Picture an army made ready BEFORE the battle: to be prepared is to have done your readying in advance.

Contingency

  • Pronunciation: /kənˈtɪn.dʒən.si/
  • Definition: A future event or circumstance that is possible but cannot be predicted with certainty, or a provision made in advance for such an event, especially in disaster planning where contingency plans outline actions to be taken if specific emergency scenarios arise.
  • Root: Latin con- = together + tangere = to touch → contingere = to befall → Late Latin contingentia = a happening
  • Origin: From late Latin contingentia ("a happening, circumstance"), from contingere ("to befall, to touch"), from con- ("together") + tangere ("to touch"); entered English in the 16th century.
  • Part of Speech: noun (plural contingencies)
  • Word Family: contingency (n), contingencies (n pl), contingent (adj/n), contingently (adv)
  • Usage: A resilient fiscal architecture does not merely budget for the expected; it institutionalises contingency reserves and pre-cleared response protocols so that a sudden drought, pandemic, or external shock does not derail the State's developmental commitments.
  • Synonyms: eventuality, possibility, emergency, exigency, uncertainty, fortuity
  • Antonyms: certainty, inevitability, necessity, predictability
  • Mnemonic: Hear "CON-TINGE" — like a faint tinge of doubt that something might TOUCH (Latin tangere, "to touch") your plans; a contingency is the uncertain event you keep a back-up plan ready to touch up.

Retrofitting

  • Pronunciation: /ˈɹɛt.ɹəʊˌfɪt.ɪŋ/ (BrE) · /ˈɹɛt.ɹoʊˌfɪt.ɪŋ/ (AmE)
  • Definition: The process of adding new components, reinforcements, or safety features to existing structures or systems that were not present in the original design, particularly strengthening older buildings to withstand earthquakes or other natural hazards.
  • Root: Coined 1950s; blend of retroactive + refit; Latin retrō = backward + English fit; first attested 1951
  • Origin: A blend of retroactive and refit, coined in the 1950s; from Latin retrō ("backward") + English fit; first attested in 1951.

  • Part of Speech: noun (the gerund/verbal noun of the verb "retrofit"); also functions as the present participle of the verb (transitive)
  • Word Family: retrofit (v/n), retrofitted (adj), retrofits (n pl), retrofitter (n)
  • Usage: A credible net-zero strategy must move beyond constructing new green infrastructure to the deep retrofitting of India's ageing building and industrial stock, since emissions embedded in existing assets cannot be wished away by future standards alone.
  • Synonyms: refitting, upgrading, modernising, retooling, adapting, renovating
  • Antonyms: dismantling, stripping, decommissioning, demolishing
  • Mnemonic: "Retro" (backward, into the old) + "fit" — you go back and fit new parts into something old. Think of fitting modern earthquake supports into a heritage building.

Key Terms

Sendai Framework Targets

  • Definition: The Sendai Framework Targets are the seven global, voluntary targets (labelled A to G) of the Sendai Framework for Disaster Risk Reduction 2015-2030 — the UN's global blueprint for reducing disaster losses — covering mortality, affected people, economic loss, critical infrastructure, national strategies, international cooperation and early-warning systems.
  • Context: The Sendai Framework was adopted at the Third UN World Conference on Disaster Risk Reduction in Sendai, Japan, on 18 March 2015, and endorsed by the UN General Assembly. It is the successor to the Hyogo Framework for Action (HFA) 2005-2015 and was the first major agreement of the post-2015 development agenda. The framework is voluntary and non-binding, adopted by 187 countries including India, and is anchored by four priorities for action and the seven "Sendai Seven" global targets, measured through 38 global indicators.
  • UPSC Relevance: This is a foundational GS3 disaster-management concept that underpins UPSC questions on international disaster-risk-reduction frameworks and their linkage with the Sustainable Development Goals and the Paris Agreement (the three post-2015 agreements). Prelims commonly tests factual recall — the adoption year/place, the number of targets, the successor-to-Hyogo relationship, and India's PM's Ten-Point Agenda announced at the AMCDRR (New Delhi, November 2016). Mains GS3 frames it around India's implementation through the NDMA, the National Disaster Management Plan (aligned to Sendai), and the India-led Coalition for Disaster Resilient Infrastructure (CDRI). No direct PYQ is cited here; treat it as a foundation concept tethered to the disaster-management and international-institutions topic families.

Hyogo Framework

  • Pronunciation: /hjˈoʊ.ɡoʊ ˈfɹeɪm.wɜːk/
  • Definition: The Hyogo Framework for Action (HFA) 2005-2015, subtitled "Building the Resilience of Nations and Communities to Disasters," was the first internationally agreed-upon plan for disaster risk reduction, adopted on 22 January 2005 at the 2nd World Conference on Disaster Reduction in Kobe, Hyogo, Japan, by 168 governments. It established five priorities for action: (1) ensure DRR is a national and local priority, (2) identify, assess, and monitor disaster risks, (3) use knowledge and education for a culture of safety, (4) reduce underlying risk factors, and (5) strengthen disaster preparedness for effective response.
  • Context: Named after Hyogo Prefecture in Japan, where the conference was held just days after the 2004 Indian Ocean Tsunami that killed over 230,000 people, lending urgency to the deliberations. The HFA succeeded the Yokohama Strategy (1994) and was itself succeeded by the Sendai Framework (2015–2030). During the HFA decade, 145 countries developed national DRR strategies.
  • UPSC Relevance: GS3 Disaster Management. Prelims tests the five priority areas, duration (2005–2015), and the distinction from Sendai (Hyogo focused on building national institutional resilience; Sendai shifted focus from managing disasters to managing risk). Mains expects comparison between Hyogo and Sendai — Hyogo's key limitation was its non-binding nature and absence of measurable global targets, which Sendai addressed with seven quantified targets and 38 indicators.

Disaster Risk Reduction

  • Pronunciation: /dɪˈzɑːs.tər ɹɪsk ɹɪˈdʌk.ʃən/
  • Definition: The concept and practice of preventing new and reducing existing disaster risk through systematic efforts to analyse and manage the causal factors of disasters, including hazard exposure, vulnerability of people and property, and environmental degradation. UNDRR defines it as actions aimed at "preventing new and reducing existing disaster risk and managing residual risk, all of which contribute to strengthening resilience." Disaster risk results from the interaction of three factors: hazard, vulnerability, and exposure.
  • Context: The concept evolved through successive UN frameworks — Yokohama Strategy (1994), Hyogo Framework (2005), and Sendai Framework (2015). For every dollar invested in DRR, an estimated $7–15 is saved in post-disaster recovery costs. India's role through CDRI (launched September 2019, 53 member countries), the Odisha cyclone model (10,000+ deaths in 1999 vs 64 in 2019), and the NDMP's alignment with Sendai are key current affairs angles.
  • UPSC Relevance: GS3 Disaster Management. Foundational concept for the entire DM section. Mains asks about the paradigm shift from reactive disaster response to proactive risk reduction. Prelims tests DRR terminology — hazard (potential damaging event), vulnerability (susceptibility), capacity (resources to cope), resilience (ability to recover).
