Forest Fire: Its Prevention and Management


From UPSC perspective, the following things are important :

Prelims level : Forest Fire Prevention and Management scheme

Mains level : Forest fires in India

The Minister for Environment, Forests and Climate Change (MoEFCC) has informed that area covering 93,273 hectares was affected by forest fires in 2019. Most of the fires have been “ground fires” burning ground vegetation.

Measures to curb Forest fires:

1) National Action Plan on Forest Fires

  • The MoEFCC has prepared a National Action Plan on Forest Fires in 2018 after several rounds of consultation with all states and UTs.
  • The objective of this plan is to minimize forest fires by informing, enabling and empowering forest fringe communities and incentivizing them to work in tandem with the State Forest Departments.
  • The plan also intends to substantially reduce the vulnerability of forests across diverse forest ecosystems in the country against fire hazards, enhance capabilities of forest personnel and institutions in fighting fires and swift recovery subsequent to fire incidents.

2) Forest Fire Prevention and Management scheme

  • The MoEFCC provides forest fire prevention and management measures under the Centrally Sponsored Forest Fire Prevention and Management (FPM) scheme.
  • The FPM is the only centrally funded program specifically dedicated to assist the states in dealing with forest fires.
  • The FPM replaced the Intensification of Forest Management Scheme (IFMS) in 2017. By revamping the IFMS, the FPM has increased the amount dedicated for forest fire work.
  • Funds allocated under the FPM are according to the 90:10 ratio of central to state funding in the Northeast and Western Himalayan regions and 60:40 ratio for all other states.
  • Nodal officers for forest fire prevention and control have been appointed in each state.

Blaze down under


From UPSC perspective, the following things are important :

Prelims level : Not much.

Mains level : Paper 1-Climate change,Forest fires.


In Australia, forest fires, among the worst in the country’s history, have been raging since September and show no signs of abating.

 Unabated fire in Australia

  • The fire, worst in Australia’s history, has been raging since September and shows no signs of abating.
  • At least 24 people lost their lives, 500 million animal have perished, and more than 12bn acres of land has turned to cinders.
  • New South Wales, the country’s worst-affected state, declared an emergency last week in its southeastern region.

Climate change and the fire

  • Australians have vented their anger at Prime Minister for playing down the blaze’s association with climate change.
  • Bushfires are actually a part of Australia’s ecosystem. Many plants depend on them to cycle nutrients and clear vegetation.
  • Eucalyptus trees in Australia depend on fire to release their seeds.
  • The prolonged blaze this year has coincided with Australia’s harshest summer.
  • Parts of the country recorded their highest recorded temperature in December.
  • Much of Australia is facing a drought that is a result of three consecutive summers with very little precipitation.
  • This, according to climate scientists, is unprecedented.
  • Australian Bureau of Meteorology’s 2018 State of the Climate report had given a hint of the change.
  • It said “Australia’s climate has warmed by just over 1 degree Celsius since 1910, leading to an increase in the frequency of extreme heat events.’’
  • This has led to more rainfall in northern Australia but created drought-like conditions in the more densely populated southeast.

Damage caused to the flora and fauna of Australia

  • Australia is home to nearly 250 animal species.
  • Some of them like the koalas and kangaroos are not found elsewhere.
  • The region also has the highest rate of native animals going extinct over the past 200 years.
  • Experts, for example, reckon that more than a quarter of the koala habitat has been consumed by the blaze.
  • The fires have also caused a drop in the bird, rodent and insect populations.


  • These creatures perished are the building blocks of the ecosystem and the fall in their population is bound to have long-term impacts. In Australia’s bushfires lies a warning about the complex ways in which climate variables interact.

Sentinel-3 World Fire Atlas


From UPSC perspective, the following things are important :

Prelims level : Sentinel-3 World Fire Atlas

Mains level : Forest fires and their global impact

Sentinel-3 World Fire Atlas

  • The Sentinel-3 World Fires Atlas Prototype product has been developed by European Space Agency.
  • It uses a method that enables it to identify all active fires at night.
  • The sensors on satellites measure thermal infrared radiation to take the temperature of Earth’s land surfaces. This information is used to detect and monitor the heat emitted by the fires.
  • The Atlas uses the satellite data to plot the number of fires occurring monthly.

Why it’s significant?

  • Quantifying and monitoring fires is important for the study of climate.
  • Forest fires have a significant impact on global atmospheric emissions, with biomass burning contributing to the global budgets of greenhouse gases, like carbon dioxide.

Forest fires on rise

  • Compared to August 2018, there were almost five times as many wildfires across the world in August 2019 the European Space Agency (ESA) has announced citing data from its Sentinel-3 World Fire Atlas.
  • August and September 2019 were also the months during which fires in the Amazon rainforest were at the centre of worldwide attention.
  • A detailed analysis of the August 2019 fires, however, shows that it was Asia that accounted for nearly half of these fires.


  • The ESA’s Copernicus Sentinel-3 mission recorded 79,000 fires in August this year, compared to just over 16,000 fires detected during the same period last year.
  • These figures were achieved by using data from the Sentinel-3 World Fire Atlas Prototype, which also provided a breakdown of these fires per continent.
  • The data revealed that 49% of the fires were detected in Asia, around 28% were detected in South America, 16% in Africa, and the remaining were recorded in North America, Europe and Oceania.

Why forest fires are sometimes a good thing


From UPSC perspective, the following things are important :

Prelims level : Not Much

Mains level : Forest fires and their global impact


  • In a rainforest-like the Amazon, massive forest fires are a disaster.
  • They irretrievably destroy the habitat of tens of thousands of plant and animal species.

Loss of nutrients

  • If the rainforest burns down, all nutrients are lost because they are stored in the plants themselves, not in the soil.
  • Despite the lush vegetation and the unique biodiversity, the soils are particularly barren and poor in nutrients.
  • Thanks to the year-round warm and humid climate, fungi and bacteria immediately decompose fallen leaves or branches and the nutrients released are reabsorbed by the roots — not the soil.
  • The thin humus layer is quickly washed out after a forest fire, and within three years of the fire nothing will grow in the exhausted soil.

A fire sensitive ecosystem

  • Scientists describe tropical rainforests like those in the Amazon, the Congo Basin and Southeast Asia as “fire-sensitive ecosystems.
  • About a third of all ecosystems worldwide are considered “fire-sensitive.”
  • In the past, severe fires tended to occur less often there due to the natural humidity, vegetation and structure.
  • If there is a prolonged drought triggered for example by the El Nino climate phenomenon or in case of purposefully started fires disastrous surface fires develop quickly.
  • The plants and animals lack a natural ability to resist and recover from fires.

Cleansing properties of forest fires

  • As devastating as forest fires are in the rainforest, the destructive power of fire is necessary for the preservation of other ecosystems, where parts of the natural fauna and flora develop only thanks to the fires.
  • Regular fires give these ecosystems their distinctive structure.
  • This is true for about three-quarters of all habitats worldwide.
  • These include the Siberian taiga, the African savannahs, the South Asian monsoon and dry forests, the Californian coniferous forests, the Australian eucalyptus forests and the Mediterranean region.

How small fires are useful?

  • Rare but very intense fires are characteristic of bush landscapes or forests.
  • They consume old and diseased trees, create new habitats and ensure an ecological rejuvenation of the tree population.
  • Intervening in these ecosystems, for instance by preventing small fires in order to protect the population, can have fatal consequences.
  • Over time, more and more combustible material accumulates. Even harmless fires can quickly turn into highly destructive walls of flames.
  • This happens time and again in Australia or in the dense pine forests in the southwest of the United States, which were once grasslands.
  • When fires occur too frequently humans have to intervene even in ecosystems that depend on fires.
  • In the Siberian taiga, fires have been breaking out more and more frequently due to a rise in the population and expanded development, destroying large areas of forest and releasing enormous amounts of carbon dioxide.

Fires give new life

  • Many plants in the southern US, in the Mediterranean region or in Australia actually need fire to survive.
  • The Douglas fir, a conifer species, survives most fires thanks to its thick bark — after a fire, it will sprout new shoots.
  • The North American lodgepole pine also needs the heat of the fire to open its cones and release seeds while the Australian grass tree needs smoke to open its seed pods.
  • After a fire, without the usually dense treetops, more sunlight reaches the forest floor and the seedlings find enough nutrients because they do not have to compete with other plant species.
  • Even some insect species need the fire to survive, including the larvae of the Australian fire beetle that can only develop in freshly burnt wood.
  • Thanks to its heat-sensitive sensors, the fire beetle can detect fires from up to 50 kilometers (30 miles) away.
  • Storks and birds of prey feast on beetles and insects made sluggish by the smoke after a forest fire.

Still catastrophic

  • Climate change is bound to increase the risk of forest fires even further.
  • Forest fires cause 15% of global greenhouse gas emissions, more than 30% of global carbon monoxide emissions, 10% of methane emissions and more than 85% of global soot emissions.
  • They contribute greatly to global warming, which in turn leads to forests becoming increasingly dry and weak.
  • This destructive cycle often makes it easy for new fires to develop.

Amazon Fires


From UPSC perspective, the following things are important :

Prelims level : Amazon Forest

Mains level : Forest fires and their global impact

  • Over the last several days, the ‘lungs of the Earth’ Amazon rainforest has been burning at a rate that has alarmed environmentalists and governments worldwide.
  • The fires are so large that they are visible from space.

Amazon Fires

  • Started in the Amazonian rainforests, the fires have impacted populated areas in the north, such as the states of Rondônia and Acre, blocking sunlight and enveloping the region in smoke.
  • The smoke has wafted thousands of miles to the Atlantic coast and São Paulo, according to the World Meteorological Organization.
  • Brazil has reported that forest fires in the region have doubled since 2013, and increased by 84% compared to the same period last year.

How did the fire start?

  • Mostly caused by farmers clearing land, the fires have thrown the spotlight on Brazilian policies and anti-environment stance.
  • The farmers had organised a “fire day” along a highway that runs through the heart of the rainforest.
  • Local farmers set ablaze to sections of the rainforest a few days ago to get the government’s attention.
  • And dry weather has further fuelled the fire.
  • The dry season creates the favourable conditions for the use and spread of fire, but starting a fire is the work of humans, either deliberately or by accident.

A cause for concern

  • The Amazon rainforest is a repository of rich biodiversity and produces approximately 20 per cent of oxygen in the Earth’s atmosphere.
  • It is also home to indigenous communities whose lives and homelands are under threat due to encroachment.
  • The Amazon basin matches the emissions released by nations in the basin. The burning of forests, therefore, implies additional carbon emissions.
  • Deforestation could lead to the Amazon’s transformation from the world’s largest rainforest to a savanna, which would reverse the region’s ecology.

Importance of Amazons

  • A National Geographic report said the Amazon rainforest influences the water cycle not only on a regional scale, but also on a global scale.
  • The rain produced by the Amazon travels through the region and even reaches the Andes mountain range.
  • Moisture from the Atlantic falls on the rainforest, and eventually evaporates back into the atmosphere.
  • The Amazon rainforest has the ability to produce at least half of the rain it receives. This cycle is a delicate balance.

Flawed environmental policies

  • Since the 1960s, the Amazon has witnessed large-scale deforestation because of cattle-ranching, logging, power projects, mining and farming.
  • Under Brazil’s Forest Code of 1965, farmers could purchase Amazon land but could farm only 20% of it.
  • Agribusiness products in 2016 represented 46% of Brazil’s exports.


Amazon Rainforests

  • The Amazon rainforest is a moist broadleaf tropical rainforest in the Amazon biome that covers most of the Amazon basin of South America.
  • This region includes territory belonging to nine nations.
  • The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%, and with minor amounts in Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana.
  • The Amazon represents over half of the planet’s remaining rainforests and comprises the largest and most biodiverse tract of tropical rainforest in the world.

Forest Fires

Explained: Why are fires frequent at the Bandipur reserve?


Mains Paper 3: Environment | Conservation, environmental pollution and degradation, environmental impact assessment

From UPSC perspective, the following things are important:

Prelims level: Bandipur Tiger Reserve

Mains level: Prevention of forest fires


  • A five-day fire that raged through the Bandipur Tiger Reserve has reportedly burnt more than 15,400 acres of forests.
  • Between February 21 and 25, the reserve saw 127 fire counts in various ranges of the 912 sq km forest.
  • While K’taka Forest Department scrambled to put out the blaze, an Indian Air Force helicopter sprayed over 19,000 litres of water in seven sorties.

Why it matters?

  • While fires are not uncommon at Bandipur, what has surprised officials is their intensity and frequency.
  • The worry now is the long-term damage to the ecosystem, which is a part of the Nilgiri Biosphere that hosts the world’s largest tiger population, at more than 575 (2014 census).
  • Over 400 fire watchers were placed, but questions have arisen whether the precautions were enough, especially since Bandipur has had frequent fires.

How susceptible is it to fires?

  • Bandipur is a dry deciduous forest in the rain shadow region of the Western Ghats, and is no stranger to fires. Periods of drought invariably lead to fires.
  • A study has shown that between 1974 and 2014, 67% of the Nilgiri Biosphere had seen some form of forest fire, with Bandipur having reported the most incidents.
  • The 2018 monsoon was particularly strong, but the year-end northeast monsoon has failed.
  • If the monsoon led to dense growth, the blistering heat since September has turned vegetation brittle and dry, with vast swathes becoming tinderboxes.
  • As with most forest fires, it is assumed that Bandipur’s ignition was man-made as miscreants set fire in multiple locations.
  • Compounding matters is the ubiquity of lantana camara, an invasive weed species native to South America, that has spread through nearly two-thirds of the forest area.

What is the impact?

  • India’s forest policy encourages a zero forest fire approach for its protected landscapes — whether it is Bandipur or the rainforests of the upper Western Ghats.
  • Scientific literature has shown this blanket approach may be doing harm to dry, deciduous forests where trees have evolved to co-exist with fire.
  • The trees in this landscape were closer to those in a savanna than in rainforests 100 km away. Trees have dramatically thicker barks, implying that they had evolved to be fire-resistant.
  • When fires are relatively frequent, adult tree mortality in these systems is very low.
  • Many saplings sprout shortly after the fire from underground reserves, and the system returns to its original state in a few years.
  • Conversely, when fires are suppressed — including by curbing the tribal practices of controlled fire burning — a greater biomass builds up that can lead to high intensity fires which affect the ecosystem negatively.
