Lesson 9 – Disaster Risk Reduction: Key Concepts, Principles & Elements

LESSON OVERVIEW

• Focus: Lesson 9 – “Key Concepts, Principles, and Elements of Disaster Risk Reduction (DRR)”
• Central idea: a paradigm shift from reactive emergency management toward pro-active risk reduction, community participation, and institutionalized, science-based planning.
• Macro-structure of lesson:
– Definitions & disaster equations
– Philippine DRRM institutions
– UNDRR 3-stage national risk-assessment cycle
– Community-Based Disaster Risk Management (CBDM): standards, principles, structures, drills
– Major DRR–related laws & global frameworks

PARADIGM SHIFT IN DRRM

• Traditional view: Disaster assumed equal to hazard (no systemic analysis).
• New view: Disaster understood as product of hazard, vulnerability, exposure, and coping capacity; emphasis on prevention, mitigation, preparedness, and resilience.

DISASTER EQUATIONS & MODELS

• Emergency Management formula: $Disaster = Hazard$
– Implies disasters unavoidable once hazards occur.
• Disaster Preparedness formula: $Disaster = Hazard + \text{Unpreparedness}$
– Highlights human role in preparedness.
• Vulnerability-capacity ratio model:
$Disaster = \frac{Hazard \times Vulnerability}{Capacity}$
– Increasing capacity or decreasing vulnerability lowers risk.
• Comprehensive model with exposure:
$Disaster = \frac{Hazard \times Vulnerability \times Exposure}{Capacity}$
– Adds spatial/temporal people-asset concentration (exposure) as critical factor.

KEY PHILIPPINE DRRM INSTITUTIONS

• NDRRMC – National Disaster Risk Reduction & Management Council
– Supervises, coordinates, monitors disaster prevention, mitigation, preparedness, response, rehabilitation & recovery nationwide.
• DSWD – Department of Social Welfare & Development
– Delivers social services, relief, cash/food assistance to vulnerable sectors before, during, after disasters.
• DOST – Department of Science & Technology
– Leads science/tech R&D; operates PAGASA & PHIVOLCS; produces hazard maps, early-warning tech.
• NEDA – National Economic & Development Authority
– Chief planning agency; integrates DRR/CCA (Climate Change Adaptation) into national development plans.
• DILG – Department of the Interior & Local Government
– Ensures LGUs’ public safety functions; capacity-builds local DRRM Offices; supervises peace and order during crises.
• OCD – Office of Civil Defense (secretariat of NDRRMC)
– Coordinates public/private agencies, evaluates DRRM program implementation, manages National Disaster Operations Center.

UNDRR-RECOMMENDED NATIONAL PROCESS (2017)

• Nations should undertake 3 iterative phases to institutionalize risk reduction:

1. Preparation & Analysis of Scope

– Governance Mechanism: assign roles & mandates at national ⇄ local levels.
– Policy & Technical Scoping: define geographic, sectoral, thematic coverage of each law/policy.
– Ancillary components:
• Data Management Plan
• Required Capacities inventory
• Terms of Reference (TORs) for all actors.

2. Risk Analysis

– Selection of Methodologies: quantitative (probabilistic modeling, GIS mapping) & qualitative (historical, participatory) tools.
– Risk Analysis Proper: identify hazards, assess vulnerabilities/exposure, quantify potential losses.
– Preparation of Outputs: maps, tables, probability curves, communication briefs.

3. Utilization of Risk Assessment for DRMD (Disaster Risk Management & Development)

– Evaluate results → integrate into local & national DRRM plans (LDRRMP, NDRRMP).
– Ensure long-term sustainability: budgeting, institutional memory, regular updating.

COMMUNITY-BASED DISASTER RISK MANAGEMENT (CBDM)

A bottom-up approach recognizing community as first responder and primary beneficiary of risk-reduction efforts.

Standards for CBDM

• People’s Participation – inclusive engagement in planning, decision-making, drill execution.
• Priority Sectors – children, elderly, PWDs, women, poor households prioritized.
• Community-Specific – tailor strategies to unique socio-cultural, geographic context.
• Existing Coping Mechanisms & Capacities – inventory local strengths; reinforce rather than replace.
• Reduce Vulnerabilities & Build Resilience – protocols to mitigate root causes (unsafe housing, weak livelihoods).
• Identify Roots of Vulnerability; Transform & Eliminate Harmful Structures – tackle poverty, marginalization, land-use issues.
• Clarify Roles of Government & NGOs – delineate LGU, CSO, private-sector responsibilities pre-, during, post-disaster.

Principles of CBDM

• Participation – “whole community” inclusion.
• Participatory Process & Content – community designs its own risk analysis & solutions.
• Responsive – hazard-specific and timely interventions.
• Integrated – link pre- & post-disaster information and actions.
• Proactive – cultivate safety culture; don’t wait for triggers.
• Comprehensive – hazards, vulnerabilities, exposure, capacities all addressed.
• Multisectoral & Multidisciplinary – engage health, education, industry, faith groups, etc.
• Empowering – training nurtures self-reliance.
• Developmental – aligns DRR with broader socio-economic growth and climate resilience.

DRRM SYSTEMS & STRUCTURES (Key Terms)

• Systems & Structures – committees, councils handling DRR functions.
• Policies & Plans – local ordinances, CLUPs (Comprehensive Land-Use Plans), contingency plans.
• Building Competencies – continuous training workshops for managers & volunteers.
• Equipment & Supplies – ambulances, rescue boats, PPEs.
• Lifelines – critical infrastructure for water, electricity, telecom.
• Early-Warning Systems – sensors, sirens, SMS alerts, community watchers.
• Search & Rescue (SAR) Operations – trained teams with topo knowledge; victim-profiling skills.
• Evacuation & Relief Operations – logistics chain: evacuation ➔ relief stockpiling ➔ distribution.

ACTUAL DRILL PRACTICE

Goal: rehearse community action to convert plans into muscle memory.

Phases of an Actual Drill

1. ALARM – audible/visual alert; public-address instructions.

2. RESPONSE – immediate protective actions (duck-cover-hold, shutoff valves, etc.).

3. EVACUATION – orderly movement to predetermined safe zones; DRRM staff facilitate.

4. ASSEMBLY – organized grouping at the site; maintain clear routes.

5. HEADCOUNT – compare attendance sheets; trigger SAR if discrepancies.

6. EVALUATION – pre-/post-drill assessment using checklists, CCTV review; identify lessons & improvements.

DISASTER RISK REDUCTION LAWS & POLICIES

• Climate Change Act of 2009 (RA 9729) – mainstreams CCA; establishes Climate Change Commission; links adaptation with DRR.
• Hyogo Framework for Action 2005-2015 – 5 priorities incl. DRR as national & local priority; strengthen preparedness.
• Sendai Framework for DRR 2015-2030 – 4 priorities; allocates approx. $\text{PHP}\,1\,\text{billion}$ per year in PH for climate programs; focus on understanding risk & building back better.
• Republic Act 10121 (Philippine DRRM Act of 2010) – institutionalizes NDRRMC, LDRRMCs; upholds right to safe environment.
• People’s Survival Fund Act 2011 (RA 10174) – financing window enhancing preparedness & “Build Back Better”.
• Presidential Decree 1566 (1978) – earlier policy: promotes transparency, LGU empowerment, participatory DRR.

REFLECTION & CONTINUING LEARNING TOOLS

• 3-2-1 Summary technique encouraged:
– 3 takeaways, 2 further curiosities, 1 key reminder.
• Inspirational quote: “We learn from every natural disaster… so we can respond to the next one better.” – Malcolm Turnbull

ETHICAL, PHILOSOPHICAL, & PRACTICAL IMPLICATIONS

• Ethical: DRR is linked to human right to life, dignity, and healthy environment.
• Philosophical: Emphasizes collective responsibility, inter-generational equity (future risk burden).
• Practical: Investment in DRR yields high benefit-cost ratios; community drill practice translates theory into lifesaving action.

KEY NUMBERS & FORMULAS AT A GLANCE

• $Disaster = Hazard$ (traditional)
• $Disaster = Hazard + \text{Unpreparedness}$
• $Disaster = \frac{Hazard \times Vulnerability}{Capacity}$
• $Disaster = \frac{Hazard \times Vulnerability \times Exposure}{Capacity}$
• People’s Survival Fund: $1\,\text{billion PHP/year}$ allocation.

REAL-WORLD CONNECTIONS

• 2020 Taal eruption: high exposure + moderate capacity ⇒ significant evacuation cost; underscores importance of CBDM drills.
• Typhoon Haiyan (Yolanda) 2013: low capacity + high vulnerability = catastrophic losses; spurred RA 10121 implementation & Sendai alignment.

STUDY REMINDERS

• Memorize disaster equations & their variables’ meaning.
• Map each Philippine institution to its unique DRR role for exam matching-type questions.
• Be able to list and explain the six phases of an actual drill in correct order.
• Cite at least three CBDM principles with definitions.
• Recall dates and core objectives of major DRR laws/frameworks (Hyogo, Sendai, RA 10121, CC Act 2009).
