Carbon Dioxide Emissions
From Forest Fires
The
recent study by the Centre for Wildfire Research highlights a significant
increase in global carbon dioxide (CO₂) emissions from forest fires, driven
largely by climate change and human activities. Here’s a breakdown of the key
findings and implications:
Key Findings
1.
Surge in CO₂ Emissions:
o
Global CO₂ emissions from forest fires have surged by 60% since 2001,
with boreal forests in Eurasia and North America contributing significantly.
o
Emissions from extratropical forests, those located outside the tropics,
have increased due to climate-induced "fire weather" conditions, such
as frequent droughts, low humidity, and high temperatures.
2.
Pyromes and Fire Patterns:
o
The study identifies "pyromes," or fire-prone regions, where
forest fires follow similar patterns due to factors like climate, vegetation,
and human activities.
o
By categorizing forests into 12 pyromes, the study aims to improve
understanding of fire dynamics, enabling better fire management and risk
assessment.
3.
Increased Fire Severity:
o
There is a 47% rise in the carbon combustion rate, indicating that fires
are burning more intensely and consuming more forest biomass.
o
Increased fire severity, combined with dry vegetation, results in more
carbon emissions and poses a greater threat to forest carbon stocks.
4.
Climate Change Impact:
o
Climate change has intensified fire conditions through prolonged
droughts, high temperatures, and increased lightning strikes, creating a
"fire weather" conducive to severe forest fires.
o
As a result, forests that traditionally acted as carbon sinks (absorbing
CO₂) are now emitting more carbon, destabilizing global carbon budgets.
5.
Challenges for Carbon Accounting and Carbon Credits:
o
Rising forest fire emissions complicate carbon accounting and greenhouse
gas (GHG) inventories, as forest fires are increasingly offsetting carbon sink
efforts.
o
For instance, Canada’s 2023 wildfires may have released CO₂ equivalent
to the carbon storage achieved in its forests over the past decade.
o
This presents a risk for carbon credit schemes and reforestation
projects, which depend on reliable estimates of carbon sequestration potential.
Implications for Forest Management and Climate
Policy
1.
Environmental Impact:
o
Forest fires destroy biodiversity, degrade ecosystems, and contribute to
air pollution by releasing harmful pollutants and particulate matter.
o
Soil degradation is a significant outcome of intense fires, as essential
nutrients are lost, affecting soil fertility and disrupting ecosystems.
2.
Human and Economic Costs:
o
Local communities suffer from the loss of resources such as timber and
food, as well as health issues due to air pollution and heat exposure.
o
The economic burden of fighting fires, restoring damaged infrastructure,
and addressing health impacts can be substantial, with forest fires impacting
local and national economies.
3.
Challenges in Fire Management:
o
Climate change has made fire management more challenging, with increased
fire frequency and intensity overwhelming traditional firefighting resources
and strategies.
o
High-intensity fires, such as canopy or crown fires, are harder to
control and often spread rapidly, causing greater damage.
The Forest Fire Scenario in India
1.
Vulnerability and Recent Incidents:
o
India’s fire season extends from November to June, with the peak in
April-May. Nearly 35% of India’s forests are fire-prone, with high-risk areas
in Northeast India, Odisha, Maharashtra, Jharkhand, Chhattisgarh, and
Uttarakhand.
o
Recent data show a rise in forest fires in India, with Uttarakhand alone
reporting over 1,300 incidents in early 2024, impacting large tracts of forest
land.
2.
Government Initiatives:
o
The National Action Plan for Forest Fires (NAPFF) and the Forest
Fire Prevention and Management Scheme (FPM) aim to reduce fire occurrences
and improve state-level firefighting capabilities.
o
The Indian Space Research Organisation (ISRO) provides satellite data
for real-time monitoring of forest fires, helping local authorities track and
respond to fire outbreaks promptly.
Global and Local Strategies for Forest Fire
Management
1.
Integrating Science and Traditional Knowledge:
o
The FAO’s fire management guidelines emphasize the importance of
combining scientific knowledge with traditional practices, particularly from
Indigenous and local communities, to improve fire prevention and control.
2.
Enhanced Reporting and Carbon Accounting:
o
Improved reporting of forest fire emissions to international bodies,
such as the United Nations, is essential to accurately assess global carbon
budgets and GHG inventories.
o
Carbon credit schemes need to account for fire risks in carbon
sequestration estimates, especially in extratropical regions, to avoid
overestimating carbon storage potential.
3.
Sustainable Fire Management:
o
In tropical regions, controlling ignition sources during fire-prone
periods and preventing forest fragmentation are crucial for reducing fire
risks.
o
In areas with a history of fire suppression, adopting ecologically
beneficial fire practices, such as controlled burns, may help prevent
high-intensity wildfires by reducing fuel loads.
Conclusion
The
increase in CO₂ emissions from forest fires is a serious challenge in the fight
against climate change. Forest fires are not only depleting carbon stocks and
destabilizing ecosystems but also posing socio-economic risks to communities
and countries worldwide. Sustainable forest management, informed by scientific
and traditional knowledge, along with accurate carbon accounting, is essential
to address the growing impact of forest fires. For India, strengthening
monitoring and prevention efforts, particularly in fire-prone areas, is
critical to safeguarding its forests and mitigating climate change impacts.

biodiversity, and outline the challenges and strategies for effective forest
fire management in India."
Model Answer
Introduction
Forest
fires, also known as wildfires or bushfires, are uncontrolled burning of
vegetation in forested areas. They play a dual role in ecosystems—while
naturally occurring fires can maintain ecological balance, uncontrolled or
frequent fires can cause devastating impacts on biodiversity and the climate.
With climate change increasing fire risks globally, India faces unique
challenges due to its vast, diverse, and fire-prone forests.
Impact of Forest Fires on Climate Change and
Biodiversity
1.
Contribution to Climate Change:
o
Carbon Emissions: Forest
fires release large amounts of carbon dioxide (CO₂) and other greenhouse gases,
contributing to global warming. The recent study by the Centre for Wildfire
Research shows that global CO₂ emissions from forest fires have increased by
60% since 2001.
o
Loss of Carbon Sinks:
Forests act as carbon sinks, absorbing CO₂ from the atmosphere. Frequent fires
destabilize these carbon stocks, turning forests from carbon sinks into carbon
sources, which amplifies the climate crisis.
2.
Impact on Biodiversity:
o
Loss of Habitat: Fires
destroy habitats for numerous species, leading to the loss of biodiversity and
endangering flora and fauna. Species that are slow to adapt or migrate are
particularly vulnerable to forest fires.
o
Soil Degradation:
High-intensity fires deplete essential nutrients in the soil, reducing
fertility and hindering vegetation recovery. This can result in long-term
ecological imbalances and erosion.
o
Air and Water Pollution:
Smoke from fires releases particulate matter and toxic compounds, which harm
air quality and impact human health. Runoff from burned areas can also pollute
water sources, affecting aquatic biodiversity.
Challenges in Managing Forest Fires in India
1.
Climate Change and Fire Weather:
o
Climate change has intensified "fire weather" conditions,
including prolonged droughts, high temperatures, and dry winds, creating an
environment where fires can easily ignite and spread.
2.
Difficult Terrain and Limited Accessibility:
o
Many of India's forests, such as those in the Northeast and the
Himalayas, are located in remote and rugged areas, making firefighting and
monitoring challenging.
3.
Resource Constraints:
o
Managing forest fires requires substantial resources, including
manpower, equipment, and funding. India’s limited firefighting resources,
especially in remote forest areas, hinder effective response and containment.
4.
Human-Induced Fires:
o
Many forest fires in India are caused by human activities, such as
shifting cultivation, poaching, and illegal logging. Increasing human
encroachment in forests adds to the risk of accidental or deliberate ignitions.
5.
Inadequate Early Warning Systems:
o
While satellite-based systems exist, the lack of localized early warning
systems in vulnerable regions hampers timely action, and communication with
forest communities is often insufficient.
Strategies for Effective Forest Fire Management
1.
Enhanced Monitoring and Early Warning Systems:
o
Use of Satellite Technology:
Collaborating with agencies like ISRO for real-time satellite data enables
timely detection of fires. Enhanced monitoring with thermal imaging can help
detect even small fires before they escalate.
o
Community-Based Warning Systems: Establishing localized early warning systems in vulnerable regions and
engaging local communities in reporting fire outbreaks can lead to faster
response times.
2.
Building Resilient Infrastructure:
o
Creating Firebreaks:
Constructing firebreaks, or cleared strips of land, can help contain fires and
prevent their spread to vulnerable areas.
o
Establishing Forest Fire Control Centers: Setting up regional control centers with trained personnel and
necessary equipment in high-risk zones can improve rapid response capabilities.
3.
Promoting Controlled Burning and Indigenous Knowledge:
o
Controlled or Prescribed Burns: Forest agencies can use controlled burning to manage fuel loads and
reduce the risk of larger wildfires. These deliberate burns also help maintain
ecosystem health.
o
Integrating Traditional Practices: Indigenous communities have valuable knowledge about fire management,
including controlled burns and maintaining natural barriers. Integrating this
knowledge with modern practices can create effective fire management
strategies.
4.
Implementing Policy Measures:
o
National Action Plan for Forest Fires (NAPFF): Launched in 2018, NAPFF focuses on community
engagement and awareness to reduce fire occurrences. Scaling up this plan with
adequate funding and technological support is essential.
o
Forest Fire Prevention and Management Scheme (FPM): This scheme, initiated in 2017, assists states
with financial and technical support for fire prevention and management, which
needs to be strengthened for greater coverage and effectiveness.
5.
Enhancing Community Awareness and Engagement:
o
Educating Local Communities:
Conducting awareness programs on fire prevention and firefighting techniques
helps reduce accidental ignitions and promotes community participation.
o
Economic Alternatives:
Providing alternative livelihoods to communities dependent on forest resources
can reduce practices like shifting cultivation, which often lead to unintended
fires.
Conclusion
Forest
fires pose a serious threat to India’s biodiversity and climate goals. The
increasing intensity and frequency of fires demand a comprehensive approach
that combines technology, policy intervention, traditional knowledge, and
community participation. By enhancing early warning systems, promoting
resilient infrastructure, and implementing sustainable forest management
practices, India can better manage and mitigate the impact of forest fires,
safeguarding its forests and contributing to global climate resilience.
