B. Why It’s Used
Paper II §5 of the TGPSC syllabus specifies “Disaster management and Planning, Four elements of disaster management: Preparedness, response, recovery and mitigation, Hazard safety legislations, role of various stakeholders and community-based disaster risk management. Integration of disaster mitigation strategy in Urban and Regional planning.” This lesson is the operational core of the disaster module — Lesson 5.1 supplied concepts; this lesson supplies the cycle, the law, the institutions, and the integration logic. The Town Planning Assistant will work with district collectors (who chair DDMAs), implement NDMA guidelines through building codes, and integrate disaster mitigation into Master Plans. The exam tests the cycle sequence, the DM Act three-tier structure, fund types, Sendai targets, and — increasingly — mainstreaming DRR into planning.
C. Mechanism in Words
-
The disaster management cycle is the standard framework for organising disaster work across time. The cycle has four phases: Mitigation (long-term measures to reduce future hazard impact — building codes, zoning, infrastructure upgrades, afforestation), Preparedness (pre-disaster activities that build capacity to respond — early warning, evacuation plans, training, stockpiling), Response (immediate post-disaster actions — search and rescue, medical aid, shelter, food, water), and Recovery (rebuilding — temporary housing, livelihood restoration, infrastructure reconstruction, “build back better”). Some frameworks split Recovery into Rehabilitation (immediate restoration) and Reconstruction (long-term rebuilding). The cycle is not strictly linear — mitigation happens continuously alongside response and recovery; “build back better” embeds mitigation into recovery.
-
The Disaster Management Act 2005 is India’s statutory framework. Enacted in the wake of the 2004 Indian Ocean tsunami, it established a three-tier institutional structure: the National Disaster Management Authority (NDMA) at the centre (chaired by the Prime Minister), the State Disaster Management Authority (SDMA) in each state (chaired by the Chief Minister), and the District Disaster Management Authority (DDMA) in each district (chaired by the District Collector / District Magistrate, with the elected Zilla Parishad chair as co-chair). The Act also established the National Institute of Disaster Management (NIDM) for capacity building and training, and the National Disaster Response Force (NDRF) — a dedicated force currently of about 12 battalions, each specialised (search and rescue, medical first response, chemical-biological-radiological-nuclear, etc.). The Act gives these authorities powers to issue binding guidelines, coordinate response, requisition resources, and direct all ministries in a notified disaster.
-
The financing architecture rests on dedicated funds at each tier. The National Disaster Response Fund (NDRF) — at the centre — finances immediate response in the event of a notified disaster (State Disaster Response Fund, SDRF, at state level is the primary first responder). The National Disaster Mitigation Fund (NDMF) — also at centre — finances mitigation projects (the corresponding state-level fund is SDMF; many states have established them, others are at various stages). The Financing Disaster Management framework is governed by Finance Commission recommendations — the 15th Finance Commission (2021–26) substantially increased state-level disaster relief allocations and recommended setting up NDMF and SDMFs systematically. The split between response and mitigation is fundamental — historically, India has spent far more on response than on mitigation, which the Sendai Framework and Finance Commission recommendations have tried to correct.
-
The Sendai Framework for Disaster Risk Reduction 2015–2030, adopted at the Third UN World Conference on Disaster Risk Reduction in Sendai, Japan (March 2015), is the operative global framework. It replaced the Hyogo Framework for Action (HFA, 2005–2015). Sendai has four priorities for action (understand disaster risk; strengthen governance; invest in resilience; enhance preparedness for effective response and to “build back better”) and seven global targets labelled (a) through (g). The most-tested targets: (a) substantially reduce global disaster mortality by 2030 (vs 2015 baseline); (b) substantially reduce the number of affected people globally; (c) reduce direct disaster economic loss in relation to global GDP; (d) substantially reduce disaster damage to critical infrastructure and disruption of basic services. Targets (e), (f), (g) cover developing countries’ enhanced implementation, multi-hazard early warning, and availability of disaster risk information. India is an active participant and hosted the 2016 Asian Ministerial Conference on DRR in New Delhi which produced the New Delhi Declaration and the Asia Regional Plan for Implementation of the Sendai Framework.
-
Hazard safety legislation in India operates through NDMA guidelines rather than separate statutes per hazard. The DM Act 2005 empowers NDMA to issue binding guidelines on specific hazards. Major guidelines published by NDMA cover: Earthquakes (2007, updated), Cyclones (2008), Floods (2008), Urban Flooding (2010 — a landmark for cities like Hyderabad), Chemical (Industrial) Disasters (2007), Chemical Terrorism (2009), Biological Disasters (2008), Nuclear and Radiological Emergencies (2009), Landslides and Snow Avalanches (2009), Tsunami (2010), Drought (2010), Cold Wave and Frost (2016), Heat Wave (2016, updated), and Thunderstorms and Lightning (2018). These guidelines translate into building codes (IS 1893 for seismic, IS 13827/13920/4326 for earthquake-resistant construction), state-level action plans, and district-level disaster management plans.
-
Community-Based Disaster Risk Reduction (CBDRR) is the operational philosophy that puts the affected community at the centre. The premise: communities themselves are the first responders — by the time outside help arrives in the first hours after a disaster, what local people have already done determines who lives and dies. CBDRR systematically maps community-level hazards, vulnerabilities, and capacities (Lesson 5.1’s framework), trains community volunteer teams in basic search and rescue, first aid, shelter management, and early warning dissemination, and integrates these into district-level plans. The classic Indian case is the Orissa State Disaster Mitigation Authority’s community-based cyclone preparedness programme post-1999, which substantially reduced deaths in subsequent cyclones. The AAPDA MIT scheme and the National Cyclone Risk Mitigation Project (NCRMP) have institutionalised CBDRR in many states.
-
Integration of disaster mitigation into urban and regional planning is the planner’s specific responsibility. This means: (a) land-use zoning that restricts development in flood plains, on steep slopes, in seismic-fault zones, in industrial-risk zones; (b) building codes that mandate seismic-resistant design (IS 1893), fire safety (NBC Part 4), and structural integrity; (c) infrastructure design with adequate drainage capacity, redundancy in water and power systems, accessible emergency routes; (d) urban form that includes open spaces for refuge, evacuation routes, and accessible critical facilities (hospitals, fire stations, shelters); (e) plan review processes that require disaster-impact assessment for major projects; (f) early warning dissemination through multiple channels (SMS, sirens, mobile apps, FM radio); (g) regular drills and exercises — schools, hospitals, ULBs. Telangana’s State Disaster Management Plan (under the SDMA) and district-level DDMPs operationalise this.
D. Core Concept Explanations
C1. The four-phase cycle — activities per phase
| Phase | Timing | Sample activities |
|---|---|---|
| Mitigation | Continuous, long-term | Building codes; land-use zoning; levees; mangrove restoration; afforestation; building-strengthening retrofits; relocating critical infrastructure out of hazard zones |
| Preparedness | Pre-disaster | Early warning systems; evacuation plans and routes; stockpiling food/water/medicine; training response teams; community drills; contingency planning |
| Response | Immediately post-disaster | Search and rescue; medical first aid; emergency shelter; food and water distribution; restoring critical communications and lifelines; coordination among agencies |
| Recovery | Weeks to years | Temporary shelter; livelihood restoration; infrastructure reconstruction; psycho-social support; “build back better” with upgraded standards; institutional learning |
C2. DM Act 2005 — three-tier structure
| Tier | Body | Chair | Function |
|---|---|---|---|
| National | National Disaster Management Authority (NDMA) | Prime Minister | National policy; national plan; guidelines; coordination |
| State | State Disaster Management Authority (SDMA) | Chief Minister | State policy; state plan; coordination within state |
| District | District Disaster Management Authority (DDMA) | District Collector / DM (co-chair: ZP chair) | District plan; on-ground coordination; first-line response |
Supporting institutions:
– NIDM (National Institute of Disaster Management) — capacity building, training, research (in New Delhi)
– NDRF (National Disaster Response Force) — 12 battalions, specialised in different hazards
– NDC (National Disaster Communication) — emergency communication backbone
C3. Funds — response vs mitigation
| Fund | Level | Purpose | Source |
|---|---|---|---|
| National Disaster Response Fund (NDRF) | Centre | Immediate response to notified disasters | Central budget + Finance Commission devolution |
| State Disaster Response Fund (SDRF) | State | Primary first response | Centre share (typically 75%) + State share (25%); 90:10 for NE/special category states |
| National Disaster Mitigation Fund (NDMF) | Centre | Mitigation projects | Central budget (15th FC recommended) |
| State Disaster Mitigation Fund (SDMF) | State | Mitigation projects | State + Centre contribution |
C4. Sendai Framework 2015–2030 — four priorities and seven targets

E. Worked Numericals and Parameter Tables
E1. NDRF battalion strength
The NDRF has 12 battalions, each of approximately 1,149 personnel (including support staff). Total personnel = 12 × 1,149 ≈ 13,800. Each battalion specialises in a particular hazard type (some in floods, some in collapsed-structure search and rescue, some in CBRN, etc.). Deployment is rotated across the country based on hazard seasonality — cyclone-prone east coast battalions during Oct–Dec, flood-prone plains during monsoon.
E2. SDRF allocation arithmetic
The 15th Finance Commission (2021–26) recommended the SDRF be funded at roughly ₹1.5 lakh crore over 5 years (2021–26), split 75:25 between Centre and States for most states (90:10 for NE/Himalayan states). For a typical state, this means an annual SDRF of about ₹30,000 crore at the national aggregate, allocated to states by a formula considering area, population, hazard exposure, and past disaster spending.
E3. Heat action plan impact
Ahmedabad’s heat action plan (post-2013) is estimated to have prevented over 1,190 deaths per year in the city since its adoption — at a programme cost of a few crore rupees annually. The cost-per-death-averted is exceptionally low. This is a benchmark for heat-prone cities like Hyderabad, Nagpur, Jodhpur, Bhubaneswar.
E4. Cyclone shelter arithmetic
A cyclone shelter designed for 1,000 people at 2.5 sq m per person requires 2,500 sq m of usable floor area. With multi-storey construction and shared facilities, a single shelter typically costs ₹1–3 crore. The NCRMP funded hundreds of such shelters along India’s east coast — each one can reduce cyclone mortality substantially in its catchment area.
F. Design Criteria
| Parameter | Standard / Typical value | Source |
|---|---|---|
| DM Act | 2005 | Parliament |
| NDMA established | 2005 (under DM Act) | DM Act 2005 |
| NDRF battalions | 12 (variable by year) | MHA / NDRF |
| Sendai Framework | 2015–2030 | UNDRR |
| Sendai priorities | 4 | UNDRR |
| Sendai global targets | 7 (a–g) | UNDRR |
| SDRF Centre:State share (general category) | 75:25 | 15th Finance Commission |
| SDRF Centre:State share (NE/Himalayan) | 90:10 | 15th Finance Commission |
| IS 1893 (seismic design) | Latest version | BIS |
| NBC Part 4 (fire and life safety) | Latest version | BIS |
| Cyclone shelter per person norm | ~2.5 sq m | NDMA cyclone guidelines |
G. Application Zones
- Master Plan integration — every Master Plan must include a disaster-risk chapter per NDMA guidelines.
- Building code enforcement — Telangana’s municipal building byelaws incorporate IS 1893 seismic and NBC fire requirements.
- Heat action plans — Hyderabad and other Telangana cities have heat action plans with cool roofs, drinking water kiosks, public cooling centres, early warning.
- Urban flood management — HMDA drainage upgrades; lake buffer enforcement; Musi catchment management.
- DDMA planning — every district in Telangana has a District Disaster Management Plan (DDMP), updated annually.
- CBDRR programmes — NCRMP and other programmes have trained thousands of community volunteers in coastal Andhra; similar programmes needed in Telangana for urban floods and heat.
H. Common Confusions
| Confusion | Reality |
|---|---|
| “Mitigation happens only after a disaster.” | False — mitigation is continuous; it is what reduces future harm. |
| “Response is the longest phase of the cycle.” | False — recovery (reconstruction) is typically the longest; response is hours to weeks. |
| “NDMA is the response force.” | No — NDMA is the policy/guideline authority. The response force is the NDRF. |
| “Sendai replaced the DM Act in India.” | No — Sendai is a global framework that India implements through the DM Act 2005 and NDMA guidelines. |
| “DDMA is chaired by the elected representative.” | No — chaired by the District Collector / District Magistrate; the Zilla Parishad chair is the co-chair. |
| “SDRF is funded entirely by states.” | No — Centre contributes 75% for general category states, 90% for NE/Himalayan. |
| “Heat waves are a notified disaster for relief under DM Act.” | Not in the standard list of notified disasters for relief eligibility, though NDMA has heat guidelines and cities have plans. |
| “Sendai has 8 targets.” | No — 7 targets (a through g). |
| “Build back better means rebuilding identically.” | False — it means rebuilding with improved standards so the next disaster causes less harm. |
