Subject: Disaster Management

  • The promise of parametric insurance

    Why in the news? 

    In 2023, natural disaster losses hit $280 billion, with only $100 billion insured, highlighting a need for innovative insurance solutions amid rising extreme weather events.

    Present Method of Disaster Risk Reduction

    • Indemnity-based Insurance Products: Indemnity-based insurance products require a physical assessment of damage after a disaster to determine the payout amount. For example Health Insurance, Motor Insurance and Travel Insurance.

    Challenges:

    • Verification Issues: When large-scale calamities strike, especially in economically disadvantaged areas, it is difficult to verify losses due to the lack of records and widespread destruction.
    • Delays in Payouts: The need for physical assessment can cause delays in providing financial assistance to the affected individuals and communities.
    • Insurance Gap: There is a significant gap in insurance coverage between developed and developing economies, leaving many vulnerable populations without adequate protection.

    Changing course and the associated limitations:

    • Parametric insurance: Payments are made based on predefined parameters of weather events (e.g., rainfall exceeding 100 mm per day for two consecutive days, specific flood levels, wind speed).The payouts are made without the need for physical assessment of losses, enabling quicker disbursements.

    Examples:

    • Disaster-prone Island Countries: Many have adopted parametric insurance for climate adaptation, moving away from risk retention models. For example, Fiji launched its first parametric insurance product in 2021
    • Morocco received $275 million in parametric insurance after a 6.8 magnitude earthquake, arranged with the help of the World Bank.
    • India has initiated crop insurance (e.g., Pradhan Mantri Fasal Bima Yojana and the Restructured Weather Based Crop Insurance Scheme).

    Associated Limitations

    • Current Focus: Primarily used for low-frequency, high-impact disasters like earthquakes, cyclones, and hurricanes.
    • Data and Infrastructure Requirements: There is challenges related to developing and maintaining the necessary infrastructure for data collection and monitoring can be challenging, especially in developing regions.
    • Affordability and Accessibility issues: It demands high premiums can still be a barrier for economically disadvantaged communities.

    Case Study of Nagaland:

    • Nagaland was the first state in India to buy parametric cover for extreme precipitation in 2021.
    • Based on lessons learned, it improved the product by fixing an absolute annual premium, duration, and rate online, allowing bidders to compete over lower threshold limits and maximized payouts.

    What can be done to ensure effectiveness? (Way Forward)

    • Precise Thresholds and Robust Monitoring: Establish clear, accurate parameters for insurance triggers and implement reliable monitoring systems to track these parameters effectively.
    • Transparent Bidding and Experience Sharing: Follow a transparent bidding process for price discovery and facilitate the exchange of best practices and lessons learned between governments.
    • Widespread Payout Systems and Household Premium Support: Develop comprehensive systems for distributing payouts and promote long-term premium payment by households, leveraging tools like Aadhaar-based payment dissemination.

    • Faster Adoption and Manufacturing of Hybrid & Electric Vehicles (FAME) India scheme: Launched in 2015 to promote electric vehicles and decrease coal consumption.

    Way forward: 

    • Strengthen Institutional and Legal Frameworks: Establish robust institutions like an independent low-carbon development commission to provide expert guidance, facilitate stakeholder consultations, and ensure informed decision-making.  
    • Promote Inclusive and Equitable Climate Action: Integrate social equity considerations into climate policies by systematically consulting vulnerable communities and those affected by technological changes.  

  • Factory accidents, a pointer to rusty inspection reform  

    Why in the news?

    In May 2024, an explosion at a reactor in a chemical factory within the Dombivli Maharashtra Industrial Development Corporation (MIDC) area caused fatalities and injuries among workers and local residents.

    Present Scenario in India       

    • India continues to witness frequent fatal industrial accidents, often due to non-compliance with safety regulations, inadequate inspections, and compromised safety practices.
    • Recent incidents, such as the Dombivli MIDC chemical factory explosion, highlight the recurring nature of these accidents and their devastating impact on lives and infrastructure.
    • There is a significant disparity between the number of registered factories and the inspection rates across states like Maharashtra, Gujarat, and Tamil Nadu.

    Causes of fatal industrial accidents   

    • Non-compliance with Safety Regulations: Many industrial accidents occur due to the failure of companies to adhere to mandated safety regulations and standards. Examples include improper maintenance of machinery, lack of safety equipment, and inadequate training of personnel in handling hazardous materials.
    • Inadequate Maintenance and Inspection Practices: Poor maintenance of industrial equipment and facilities can lead to malfunctions and accidents. Insufficient or irregular inspection practices contribute to undetected hazards and safety violations that increase the risk of accidents.
    • Human Error and Unsafe Practices: Accidents often result from human errors such as negligence, fatigue, or lack of training. Unsafe work practices, including shortcuts taken to save time or reduce costs, can compromise safety standards and escalate the likelihood of accidents.

    Need for the right reforms 

    • Strengthening Regulatory Framework: Reforms should focus on updating and strengthening safety regulations to align with international standards and best practices. There is a need to close loopholes and ambiguities in existing laws to enhance clarity and enforceability.

  • How urban expansion makes Delhi susceptible to flooding? 

    Why in the news?

    Heavy rain brought Delhi and NCR to a standstill, causing severe water-logging, traffic snarls, power cuts, property damage, and 11 deaths from structural collapses and electrocution.

    • Climate change and rising temperatures have intensified the overflow of rivers and lakes, snowmelt, storm surges (such as hurricanes and cyclones), and abnormally heavy rains. This, coupled with locational vulnerabilities, has resulted in increased instances of urban flooding.

    Principal Reasons Behind Chronic Urban Flooding in Delhi

    • Unchecked Urban Expansion: Rapid, ill-planned urban growth without considering natural topography and drainage patterns.
    • Inadequate Drainage Systems: Existing drainage systems are unable to handle high-intensity rainfall, leading to significant runoff.
    • Concrete Overdevelopment: Excessive construction on low-lying areas and flood plains, leaving little room for water absorption.
    • Destruction of Water Bodies: Reduction of water bodies that could manage floodwaters, with many converted into real estate.
    • Neglect of Water in Urban Planning: Lack of a comprehensive water masterplan that integrates water management into urban development.

    Present Scenario of Rapid Urbanization in Delhi NCR

    • Fastest Urban Expansion: Delhi is one of the fastest-growing cities globally, with its geographic size almost doubling between 1991 and 2011.
    • Population Growth: Predicted to overtake Tokyo as the world’s most populous city by 2030, with an estimated population of 39 million.
    • Urban Sprawl: Expansion primarily on the peripheries, converting rural areas into urban zones, and rapid urbanization in NCR cities like Ghaziabad, Faridabad, Noida, and Gurugram.

    Challenges and Limitations

    • Topographical Neglect: Building in low-lying areas and on flood plains, disrupting natural drainage and increasing flood risks.
    • Inadequate Infrastructure: Insufficient desilting of drains, inadequate stormwater management systems, and improper solid waste management.
    • Lack of a Water Masterplan: Absence of comprehensive planning for clean and wastewater flows, leading to issues like the flooding of new infrastructures like the Pragati Maidan Tunnel.
    • Reduction of green space and water bodies: Conversion of green spaces and water bodies into concrete developments, further aggravating flood situations.
    • Inconsistent Urban Planning: No systematic approach to integrating natural water flows and gradients into urban development plans.

    Recommendations (Way Forward)

    • Integrated Urban Planning: Develop a water masterplan that prioritizes water management in urban development.
    • Protection of Water Bodies: Preserve and restore existing water bodies to manage floodwaters effectively.
    • Sustainable Development: Implement policies to prevent construction in low-lying and flood-prone areas.
    • Infrastructure Improvement: Enhance drainage systems, desilting processes, and solid waste management to reduce water logging.
    • Public Awareness: Increase awareness about the importance of sustainable urban planning and the risks of unchecked urbanization.
    Case study: Copenhagen, Denmark has an excellent “Five Finger Plan” that integrates urban infrastructure, transport, and green spaces. The city emphasizes sustainability, public life, and sensitive development. Indian Government can consider this plane.

  • Why heatwaves have not been included as a notified disaster in the Disaster Management Act?

    Why in the news?

    The current period of intense heat in several regions has once more sparked debates about the potential inclusion of heatwaves as officially recognized disasters under the Disaster Management (DM) Act of 2005.

    What are Notified Disasters?

    • According to the Disaster Management (DM) Act, 2005, a disaster is defined as a “catastrophe, mishap, calamity, or grave occurrence” arising from natural or man-made causes that result in substantial loss of life, destruction of property, or environmental damage and is beyond the coping capacity of the affected community.
    • Funds: The DM Act allows states to draw money from the National Disaster Response Fund (NDRF) and the State Disaster Response Fund (SDRF) for managing these disasters.
    • Current Notified Disasters: There are currently 12 categories of notified disasters: cyclones, drought, earthquake, fire, flood, tsunamis, hailstorms, landslides, avalanches, cloudbursts, pest attacks, and frost and cold waves.

    Why Heatwaves Were Not Included as Notified Disasters?

    • Common Occurrence: Heatwaves were historically considered regular events during summer months in many parts of India. They were not seen as exceptional or unusual disasters warranting specific disaster management provisions under the DM Act, 2005.
    • Perception of Predictability: Unlike sudden-onset disasters such as earthquakes or cyclones, heatwaves were perceived as relatively predictable and part of seasonal weather patterns. This perception led to a belief that they could be managed through general public awareness and local interventions rather than formal disaster response mechanisms.
    • Not fit in definition of Disaster: When the DM Act was formulated, disasters were defined as events that caused substantial loss of life, property, or environmental damage beyond the coping capacity of the affected community. At that time, the impacts of heatwaves were typically viewed as localized health issues rather than widespread disasters.
    • Lack of Urgency: There was a lack of urgency in recognizing heatwaves as disasters requiring national-level response frameworks. The focus of disaster management efforts initially leaned towards more acute and visible calamities like cyclones, floods, and earthquakes.

    Why is the Centre Not Adding Heatwaves as a Notified Disaster Now?

    • Financial Concerns: One of the primary concerns is the potential financial burden of declaring heat waves as a notified disaster. Under the current provisions, the government is obligated to provide monetary compensation for lives lost during notified disasters, which is set at Rs 4 lakh per victim.
    • The reluctance of Finance Commissions: Despite requests from various states, the 15th Finance Commission has not recommended adding heatwaves to the list of notified disasters. They argue that the existing categories adequately cover disaster response needs, and they have provided provisions for states to utilize a portion of the State Disaster Response Fund (SDRF) for local disasters like heatwaves.

    Conclusion: Engage with the Finance Commission and other relevant bodies to reassess the inclusion of heatwaves as a notified disaster. Highlight the evolving nature of heat waves, their increasing frequency, and the need for dedicated funding and support mechanisms.

    Q Climate change’ is a global problem. How India will be affected by climate change? How Himalayan and coastal states of India will be affected by climate change?  (UPSC IAS/2017)

  • What’s missing in the disaster database?

    Why in the news?

    The Food and Agriculture Organization (FAO) of the United Nations noted a rise in global disasters from roughly 100 yearly in the 1970s to about 400 in recent years, influenced partly by reporting biases.

    Recent Observations

    • Increase in Disaster Events: The number of disaster events reported worldwide has risen from 100 events per year in the 1970s to around 400 per year in the last 20 years. Patterns in disaster data reveal factors such as increased resilience, climate change, and improved humanitarian response.
    • Improved Reporting: Reporting of small events, particularly those with fewer than 200 deaths, has increased significantly since the 1980s and 1990s. Historical data mainly included major events due to limited interest and capacity for data collection in earlier periods.

    Missing Data and Limitations of Disaster Databases

    • Biases and Gaps in Historical Records: Earlier records predominantly captured major disasters, with smaller events often missing. Data coverage is particularly poor in low-income regions such as Sub-Saharan Africa and South Asia, where economic losses from disasters are frequently underreported.
    • Missing Economic Damage and Insured Losses: More than 40% of disasters between 1990 and 2020 lacked estimates of monetary damages. Insured damages were missing in 88% of disaster reports, and 96% needed records of reconstruction costs.
    • No coverage of Heat Events and Health Impacts: Reporting of heat events is concentrated in a few countries, suggesting underreporting in other regions. Indirect health effects of extreme temperatures, such as increased cardiovascular disease risk, are challenging to quantify and often underestimated.

    Need for Data (Way Forward) 

    • Improving Data Coverage: Enhanced data collection in low-income regions and better integration of smaller events into disaster databases are crucial.
    • Accurate Health Impact Quantification: Improved methods for estimating indirect health effects of extreme temperatures and other disaster-related conditions are needed. Utilising statistical methods to capture the broader health impacts of disasters can aid in better policy formulation.
    • Policy and Resilience Planning: Reliable and comprehensive disaster data are essential for effective policy-making and resilience planning. Data-driven insights and predictive analytics can help foresee the long-term impacts of disasters and guide regulatory measures to enhance disaster preparedness and response.

  • What are fire safety rules, and why are there compliance challenges? | Explained 

    Why in the News?

    Recent fire tragedies at a Rajkot gaming zone and a Delhi children’s hospital that killed 40 people highlight the urgent need for stricter fire safety enforcement.

    According to the latest Accidental Deaths and Suicides in India (ADSI) report

    • It was released by the “National Crimes Records Bureau (NCRB)”
    • In 2022, 7,435 people died in over 7,500 fire accidents. This data shows that heavy casualties from fire accidents persist, with no lessons learned from the 1997 Uphaar Cinema tragedy or the 2004 Kumbakonam fire that killed 90 schoolchildren.

    What are the various laws and guidelines which stipulate rules around fire safety in buildings? 

    • National Building Code (NBC): Published by the Bureau of Indian Standards (BIS) in 1970, last updated in 2016.
      • Part 4 of NBC is about the details of fire safety measures, including construction guidelines, materials, and safety protocols. They are mandatory for states to incorporate NBC recommendations into local buildings.
    • Model Building Bye Laws 2016: It is issued by the Ministry of Housing and Urban Affairs. It guides States/UTs in framing building bylaws with norms for fire protection and safety.
    • State Fire Services Act: Fire services are a state subject, and individual states have their own Fire Services Acts or building bylaws.
    • National Disaster Management Authority (NDMA) Guidelines: Provide fire safety instructions for homes, schools, and hospitals. Include recommendations on maintaining safety spaces, exit mechanisms, dedicated staircases, and evacuation drills.

    Key Points from Fire Safety Regulations by Government:

    • Building Classification: Buildings are classified based on occupancy (e.g., Residential, Institutional, Assembly). Specific measures for high-rise buildings, educational institutes, hotels, etc.
    • Construction Material: Use of non-combustible materials. Internal walls of staircases should have a minimum 120-minute fire rating.
    • Electrical Safety: Flame retardant wiring and cabling. Separate shafts for different voltage wiring, sealed with fire-stop materials.
    • Emergency Power and Signage: Provision of emergency lighting, fire alarm systems, and public address systems. Clear exit signage and escape lighting.
    • Technological Measures: Automatic fire detection and alarm systems.Down-comer pipelines, dry riser pipelines, automatic sprinklers, fire barriers, and fireman’s lifts.

    Challenges in Fire Safety Compliance

    • Lack of Uniform Legislation: Fire safety rules exist in all States, with many drawing from the NBC. However, due to the absence of uniform safety legislation and the NBC being a “recommendatory document,“ its provisions are frequently ignored at the local level.
    • Inadequate Fire Safety Audits: Local bodies fail to conduct regular fire safety checks, leading to non-compliance.
    • Staff Shortages: Insufficient staffing in fire departments exacerbates enforcement issues.
    • Community Awareness and Preparedness: Need for better community awareness and training on fire safety protocols and emergency response.

    Judicial responses to negligence over Public Safety

    • Apex Court: The Judiciary has frequently pulled up state authorities for failure to enforce fire safety regulations. It highlighted the laxity in compliance and the need for stringent enforcement.
    • Legal Actions: Cases like the Rajkot gaming zone fire reveal the consequences of not adhering to fire safety norms. Courts have mandated regular fire safety audits and strict adherence to NBC guidelines.
    • The National Institute of Disaster Management (NIDM) emphasized the need for building community resilience and compliance with safety norms.
    • The report on “Fires in India: Learning Lessons for Urban Safety” underscored the failure of authorities to learn from past tragedies and enforce fire safety measures.

    Way forward:

    • Building some National Standards: The National Building Code (NBC) needs to be converted from a recommendatory document to a mandatory standard across all states.
    • Regular Inspections: Mandate regular and frequent fire safety audits by local authorities.
    • Transparent Assessment: Allow third-party certified agencies to conduct independent fire safety audits to ensure unbiased assessments.

  • Cyclone Remal to make landfall

    Why in the News?

    • Cyclone Remal is forecasted to make landfall between Sagar Island in West Bengal and Bangladesh’s Khepupara on Sunday midnight.
    • The name ‘Remal’ originates from Oman and means ‘sand’ in Arabic.

    What are Cyclones?

    • Cyclones are wind systems rotating inwardly towards an area of low atmospheric pressure. They are categorised into Tropical (Temperature-induced) and Temperate (extra-tropical) cyclones(airmass-induced).
    • Formation Conditions: Tropical cyclones originate in warm regions, requiring conditions such as
    1. Warm sea surface (> 27°C),
    2. Coriolis Force,
    3. Pre-existing low-pressure systems,
    4. Small vertical wind speed differences, and
    5. Upper air divergence.

    Characteristics of Tropical Cyclones:

    • They form over warm water bodies due to energy derived from the condensation of warm water within cumulonimbus clouds.
    • Wind rotation is influenced by the Coriolis force, resulting in anti-clockwise rotation in the northern hemisphere and clockwise in the southern hemisphere.

    Regional Movement of Cyclones:

    • In the northern hemisphere, cyclones initially move westward under earth rotation and the Easterlies.
    • As they progress towards higher latitudes, the Coriolis force deflects them rightward, towards north and later east.
    • By 30° latitude, the diminished warmth halts cyclone activity.

    Naming of Cyclones: 

    • Responsibility of RSMCs and TCWCs: The naming of cyclones that form in every ocean basin across the world is carried out by the Regional Specialised Meteorological Centres (RSMCs) and Tropical Cyclone Warning Centres (TCWCs).
    • Procedure in the North Indian Ocean: For north Indian Ocean including Bay of Bengal and Arabian Sea, the RSMC, New Delhi assigns the name to tropical cyclones following a standard procedure.
    • Agreement by WMO/ESCAP Panel: The WMO/ESCAP Panel on Tropical Cyclones in 2000 agreed in principle to assign names to the tropical cyclones in the Bay of Bengal and Arabian Sea.
    • Selection Process: Each country would sent their suggestions, based on which the Panel would finalise a list.
    • Retirement of Names: Generally, names of some storms that cause widespread damage and deaths are usually retired and are not brought back or reused later, at least for 10 years. These names are then replaced with new names.
    • Unique Policy for North Indian Ocean: Unlike in other regions, the names of tropical cyclones over the north Indian Ocean once used, will cease to be used again.

    Destruction Caused by Cyclones:

    • Strong Winds/Squall: Cyclones cause infrastructure damage through high-speed winds.
    • Torrential Rains and Inland Flooding: Heavy rainfall leads to floods, soil erosion, and embankment weakening.
    • Storm Surge: Abnormal sea level rise inundates coastal regions, causing floods, erosion, and destruction.

    PYQ:

    [2015] In the South Atlantic and South Eastern Pacific regions in tropical latitudes, cyclone does not originate. What is the main reason behind this?

    (a) Sea Surface temperature are low

    (b) Inter Tropical Convergence Zone seldom occurs

    (c) Coriolis force is too weak

    (d) Absence of land in those regions

  • A lesson from Taiwan in quake resilience

    Why in the news? 

    On April 3, Taiwan was struck by an earthquake of 7.4 magnitude. This was strongest in last 25 years.

    Reason behind the earthquake in Taiwan

    • In the Taiwan region, the Philippine Sea plate is moving northwest towards the Eurasian plate at a velocity of about 7.8 cm per year, which is faster than the motion of the Indian plate. 
    • Lying 160 km off the coast of China, Taiwan was formed at a convergent boundary of the Philippine and Eurasian plates in the western Pacific Ocean. It is a country of strong earthquakes.

    Why other countries should take lesson from Taiwan in quake resilience?

    • In 1999, the Chi-Chi earthquake of magnitude 7.7 occurred in the central part of Taiwan and impacted the western region. It killed more than 2,430 people and left 11,305 wounded. It caused more than 50,000 buildings to collapse and partially damaged as many.
    • In 2024, Hualien earthquake killed at least 13 people and injured about 1,000. Most of the deaths were caused by earthquake-triggered rockfalls and not by toppled buildings. Despite being of nearly comparable magnitude, the 2024 earthquake has caused minimal damage compared to the 1999 earthquake.

    Taiwan’s earthquake preparedness

    • Advanced Monitoring and Early Warning Systems: Taiwan boasts the most advanced earthquake-monitoring network and early warning systems, allowing for quick detection and alerting of seismic activity.
    • Public Awareness Campaigns and Drills: Widespread awareness campaigns and regular drills on earthquake safety have significantly improved the public’s understanding of earthquake risks and proper safety protocols.
    • Government Regulations and Incentives: The government constantly updates earthquake safety requirements for both new and existing buildings. Additionally, incentives such as subsidies are offered to residents to improve the quake resistance of buildings, encouraging compliance with safety standards.
    • Scientific Judgments for Seismic Risk: Utilizing knowledge of earthquake frequency and severity in different areas, Taiwan is able to make sound scientific judgments regarding seismic risk.
    • Utilization of New Technologies: Taiwan employs cutting-edge technologies such as seismic dampers and base isolation systems to enhance building resilience. For example, Taipei 101, the nation’s iconic building, features a tuned mass damper—a massive steel sphere suspended by cables within the tower—which acts as a pendulum to counteract building motion during earthquakes.

    What India can learn from Taiwan?

    • Importance of Seismic Safety Regulations: India, especially in tectonically unstable regions like the Himalayas, must prioritize seismic safety regulations in all infrastructure projects.  
    • Customized Seismic Codes: Similar to Taiwan, India should develop seismic codes tailored to specific regions based on local earthquake activity, building types, and construction materials. These customized codes can better address the unique seismic risks faced by different parts of the country.
    • Utilization of Traditional Architectural Styles: In some parts of India, traditional architectural styles may possess inherent earthquake resistivity. By rediscovering and encouraging the use of these traditional techniques, India can promote earthquake-resistant building practices that are culturally and environmentally sustainable.
    • Integration of Seismic Zonation Maps: Indian code IS 1893 already specifies seismic designs based on seismic zonation maps. It’s crucial for India to integrate these maps effectively into urban planning and construction practices to ensure that buildings are designed and located in accordance with seismic risk assessments.

    Conclusion

    Earthquakes is natural disasters with unpredictable occurrences, can have devastating effects on society. However, their impact can be mitigated through preventive measures such as early warning systems, construction regulations, and raising awareness about earthquake preparedness.

  • On India’s ‘heat action plans’ | Explained

    Why in the news?

    Come summer, we are used to seeing heat alerts from the India Meteorological Department (IMD) for various parts of India. This year, these alerts began in February itself.

    What is a heatwave?

    • According to the IMD, the definition of a heatwave depends on the physiography of regions.
    • The IMD will declare a heatwave if the maximum temperature recorded at a station is 40 degrees Celsius or more in the plains, 37 degrees Celsius or more in the coast, and 30 degrees Celsius or more in the hills.

    Heat Action Plans (HAPs) to tackle heatwave 

    • Aim: HAPs aim to increase preparedness and lower the adverse impacts of extreme heat by outlining strategies and measures to prepare for, address, and recover from heat waves.
      • The National Disaster Management Authority and IMD are reported to be working with 23 States to develop HAPs.
    • Issue with Database: There is no centralized database on HAPs, but at least 23 HAPs exist at the State and city level, with a few States, such as Odisha and Maharashtra, laying out district-level HAPs.

    Key components of Heat Action Plans (HAPs)  

    Limitation 

    • Challenges related to Determining Heatwaves: While a national threshold is currently used to determine heatwaves, determining them at smaller scales such as states, districts, and cities poses a challenge due to variations in local factors like the urban heat island effect, type of roofing, and proximity to water or green bodies, as well as humidity.
    • Inconsistent Methods and Vulnerability Assessments: The methods used for vulnerability assessments in HAPs are inconsistent because of the diverse physiography of regions
    • Addressing Vulnerable Populations: While HAPs prioritize protecting vulnerable populations, targeted interventions often fail to account for varying needs based on local socio-economic and demographic factors.
    • Resource Allocation and Financing: Implementation of HAPs varies depending on local government priorities and available capacities because at the local level Fund crunch.
    • Integration and Collaboration: HAPs are currently standalone plans with limited finance, highlighting the need for integration with broader action plans promoting urban resilience and climate adaptation to pool resources effectively.

    Way Forward:

    • Determination at Local Scales: Invest in local monitoring systems that capture variations in temperature, humidity, and other relevant factors.
    • Standardizing Methods: Establish guidelines for conducting vulnerability assessments that account for diverse physiography and local context.
    • Tailoring Interventions: Conduct comprehensive community consultations to understand the unique needs of vulnerable populations in different localities.
    • Funding and Resources: Advocate for increased funding for HAPs at the national and local levels through budget allocations, grants, and public-private partnerships.
    • Integration and Collaboration: Establish inter-agency task forces or committees to coordinate HAPs with other relevant initiatives, such as urban planning, public health, and disaster management.
