Disaster Management (Amendment) Bill, 2024
- 05 Sep 2024
In News:
On August 1, 2024, the central government introduced the Disaster Management (Amendment) Bill in the Lok Sabha. This Bill, aimed at amending the existing Disaster Management Act of 2005, has been proposed in response to the increasing frequency of climate-induced disasters. However, the Bill’s provisions have raised concerns about further centralisation of disaster management processes, which may complicate and delay disaster response efforts.
Centralisation Concerns
The Bill continues the trend of centralising disaster management, a feature already prevalent in the 2005 Act. It grants statutory status to existing bodies like the National Crisis Management Committee (NCMC) and the High-Level Committee (HLC), potentially complicating the disaster response process. This centralised approach has previously led to delays, such as the late disbursement of funds to Tamil Nadu and Karnataka, contrary to the Act's intended rapid response.
Proposed Changes
Strengthening NDMA and SDMAs: The Bill aims to bolster the role of the National Disaster Management Authority (NDMA) and State Disaster Management Authorities (SDMAs) by having them prepare disaster management plans directly. It also introduces Urban Disaster Management Authorities (UDMAs) for state capitals and major cities, although these bodies may face challenges due to insufficient financial devolution.
Database and Staffing: The Bill mandates the creation of comprehensive disaster databases at national and state levels and allows the NDMA to appoint its own staff, subject to central government approval.
Issues with the Current Definition of ‘Disaster’
Heatwaves Exclusion: On July 25, 2024, the Minister of State for Science, Technology, and Earth Sciences announced that heatwaves will not be classified as a notified disaster under the Act. This decision aligns with the 15th Finance Commission’s view and maintains a restricted list of disasters eligible for assistance, which includes cyclones, droughts, earthquakes, and floods, but excludes climate-induced phenomena like heatwaves.
Inadequate Definition: The existing definition of "disaster" in the Act and the Bill remains narrow, failing to encompass climate-induced events such as heatwaves, which are increasingly recognized globally as significant disasters. Data from the India Meteorological Department shows a record number of heatwave days and related fatalities, highlighting the need for a broader disaster definition.
Critical Issues
Central-State Dynamics: The Bill’s centralisation raises questions about the balance of power between central and state governments. There are concerns that states will remain heavily dependent on central funds, complicating disaster management and response.
Lessons Unlearned: Despite being an update to the 2005 Act, the Bill appears to overlook past shortcomings, including delays in financial preparedness and response. A focus on cooperative federalism and effective disaster management should prioritize practical solutions over a central versus state blame game.
Future Directions: Addressing the challenges of climate-induced disasters and ensuring effective financial and operational preparedness requires revisiting and refining the disaster management framework. Emphasizing cooperative federalism and proactive disaster management strategies will be crucial in improving disaster resilience and response in the face of escalating climate risks.
Can Kerala access funds from the Loss and Damage Fund?
- 06 Sep 2024
In light of the recent landslides in Kerala’s Wayanad district, the question arises whether subnational entities like Kerala can access the United Nations Framework Convention on Climate Change (UNFCCC)’s Loss and Damage Fund (LDF). While the need for compensation is clear, the process of accessing climate funds is complex.
What is the Loss and Damage Fund (LDF)?
- Established at COP27 in Egypt, the LDF aims to support regions experiencing economic and non-economic losses from climate change.
- Includes extreme weather events and slow-onset processes like rising sea levels.
- Managed by a Governing Board, with the World Bank as the interim trustee.
- The Board is developing mechanisms for resource access, such as direct access, small grants, and rapid disbursement options.
- Concerns exist about the speed and accessibility of climate funds, which may affect their effectiveness in immediate disaster recovery.
What has been India’s Role?
- India faced over $56 billion in weather-related damages from 2019 to 2023. Despite this, its National Climate Action Policy prioritizes mitigation over adaptation, leading to limited engagement in Loss and Damage dialogues at COP meetings.
- High vulnerability in certain regions could benefit from active participation in these dialogues.
- India needs a clear legal and policy framework for climate finance, focusing on locally led adaptation, which is vital for vulnerable communities.
- The Union Budget 2024’s introduction of a climate finance taxonomy raises hopes for increased international climate finance.
- Without clear guidelines for accessing loss and damage funds, frontline communities remain at risk.
- India should advocate for decentralized fund disbursement methods from the LDF, contrasting with the centralized systems used for other climate funds.
What have been State Interventions?
- State governments, such as Kerala, often bear the financial burden of disaster recovery.
- Example: The Rebuild Kerala Development Programme post-August 2018 floods, funded by World Bank and KfW Development Bank loans.
- Focused on infrastructure reconstruction, including roads and bridges.
- Lack of a standardized method for comprehensive disaster damage assessments, especially for slow-onset events, may mean significant loss and damage needs go unassessed.
- This could hinder India’s ability to access the LDF.
- The Wayanad situation highlights broader challenges in accessing and managing climate finance for loss and damage.
- A clearer domestic policy framework focusing on locally led adaptation and defined guidelines for accessing loss and damage funds is needed for better climate change protection.
Glacial Lake Outburst Floods
- 04 Apr 2024
Why is it in the News?
Recently, the Uttarakhand government has constituted two teams of experts to evaluate the risk posed by five potentially hazardous glacial lakes in the region.
What is Glacial Lake Outburst Flood (GLOF)?
- A GLOF denotes the sudden release of meltwater from a moraine or ice-dammed glacial lake, typically due to dam failure.
- These events pose significant hazards, often resulting in catastrophic flooding downstream, leading to substantial loss of life and property.
- GLOF can be triggered by several factors, including earthquakes, heavy rains, and avalanches.
Key Features of GLOFs:
-
- Sudden water releases.
- Rapid occurrences lasting hours to days.
- Large downstream river discharges.
Threats Posed by GLOFs in the Himalayan Regions:
- Climate Change Impact: Climate change-induced glacier melt accelerates the formation or expansion of glacial lakes, heightening the risk of GLOFs.
- Vulnerability of Moraines and Dams: Glacial lakes situated behind unstable moraines or natural dams are prone to breaching, as evidenced by events like the Kedarnath floods in 2013.
- Immediate Flood Risks: Abrupt water releases trigger massive floods, causing extensive damage to homes, and infrastructure, and triggering landslides and sedimentation.
Mitigation Strategies for GLOFs:
- Risk Assessment and Zonation: Identify high-risk areas and implement necessary mitigation measures, including mapping and modeling, as outlined in the 'Guidelines for Preparation of Disaster Management Plans for Glacial Lake Outburst Floods (GLOF)'.
- Early Warning Systems: Establish monitoring networks with sensors to detect changes in glacial lakes and provide timely warnings to vulnerable communities.
- Utilization of Technology: Leverage remote sensing and GIS-based tools for monitoring glacial lakes and surrounding areas.
- Regulation of Construction: Implement construction codes to regulate development in high-risk zones, exemplified by the 'Guidelines for the Construction of Earthquake Resistant Buildings' developed by the NDMA.
- Capacity Building Initiatives: Enhance skills and resources through training programs conducted by institutions like the National Centre for Disaster Management, in collaboration with the private sector and NGOs.
- Infrastructure Development: Invest in infrastructure to redirect potential floodwaters away from communities and critical infrastructure.
Nilgiris Forest Fire
- 19 Mar 2024
Why is it in the News?
The Indian Air Force (IAF) has deployed its assets to aid the local administration in dousing the raging forest fire that started recently in Tamil Nadu's Nilgiris district.
What is a Forest Fire?
- A forest fire, also known as a wildfire, is an uncontrolled fire that occurs in forested areas or other vegetated landscapes.
- These fires can spread rapidly, fueled by dry vegetation, high temperatures, low humidity, and strong winds.
- Once ignited, they can quickly grow in size, consuming vast areas of land, vegetation, and wildlife habitat.
- Wildfires pose significant risks to human safety, property, ecosystems, and air quality.
Causes of Forest Fire:
- Forest fires are caused by Natural causes as well as man-made causes.
- Natural causes: Many forest fires start from natural causes such as lightning which sets trees on fire.
- However, rain extinguishes such fires without causing much damage. High atmospheric temperatures and dryness (low humidity) offer favorable circumstances for a fire to start.
- Man-made causes: Fire is caused when a source of fire like naked flame, cigarette or bidi, electric spark, or any source of ignition comes into contact with inflammable material.
- Natural causes: Many forest fires start from natural causes such as lightning which sets trees on fire.
Types of forest fire:
- Surface Fire: This type of forest fire spreads primarily along the ground, consuming surface litter such as dry leaves, twigs, and grasses.
- The flames engulf the forest floor as they advance.
- Underground Fire: Underground fires, also known as muck fires, burn with low intensity beneath the surface, consuming organic matter and surface litter.
- These fires often spread slowly and can continue burning for months, destroying vegetative cover.
- Ground Fire: Ground fires occur in sub-surface organic fuels such as duff layers under forest stands or organic soils of swamps.
- They burn herbaceous growth and organic matter beneath the surface, often transitioning from smoldering underground fires.
- Crown Fire: Crown fires involve the burning of the crowns of trees and shrubs, sustained by a surface fire.
- They are particularly hazardous in coniferous forests, where resinous material can fuel intense flames.
Frequency of Forest Fire in India:
- Seasonality: Forest fires in India are prevalent from November to June, with peak activity typically occurring in April and May, encompassing both small-scale and large-scale incidents.
- Vulnerability: The 2019 India State of Forest Report (ISFR) highlighted that over 36% of the country's forest cover is susceptible to frequent fires, with 4% categorized as extremely prone and an additional 6% as highly fire-prone.
- Affected Regions: Dry deciduous forests experience severe fires, with Northeast India, Odisha, Maharashtra, Jharkhand, Chhattisgarh, and Uttarakhand being particularly vulnerable areas.
- Recent Incidents: Notable fire outbreaks occurred in 2021 across Uttarakhand, Himachal Pradesh, Nagaland-Manipur border, Odisha, Madhya Pradesh, and Gujarat, including wildlife sanctuaries.
- In 2023, Goa faced large bushfires under investigation for potential human causes.
- 2024 Trends: Recent reports indicate heightened fire activity in Mizoram, Manipur, Assam, Meghalaya, and Maharashtra, with increased incidents along the Konkan belt, coastal Gujarat, southern Rajasthan, Madhya Pradesh, coastal Odisha, Jharkhand, Andhra Pradesh, Karnataka, and Tamil Nadu.
- Southern India: While Andhra Pradesh and Telangana witness fire incidents, forests in southern India, primarily evergreen or semi-evergreen, are less prone to fires, although Tamil Nadu has experienced recent wildfires.
Reasons Behind This Year's Fires:
- Climate Factors: Dry conditions, high temperatures, clear skies, and light winds have fueled forest fires in southern India.
- Temperature Trends: February 2024 was exceptionally hot, making it the hottest month in southern India since 1901.
- Heat Accumulation: Above-average temperatures over the past months led to a buildup of heat, drying out biomass in forests ahead of the summer season.
- Excess Heat Factor: Western Andhra Pradesh and Karnataka are experiencing higher-than-normal EHF values, increasing the risk of heat waves.
- Mild Aridity: Lack of rain and high temperatures have classified most districts in southern India as mildly arid.
