India’s Forest Fires Surge by 10-Fold in Two Decadesand Cost India INR 1,101 Crore Per Year
By Bivash Ranjan
Fire, an element that has played an integral role in human society, has been a vital component of healthy forest ecosystems. Its benefits include recycling nutrients, supporting tree species in regrowth, removing exotic and invasive species, and maintaining habitats for a long time. However, recent years have seen a significant increase in the intensity, frequency, and spread of forest fires. These fires now pose one of the key threats to forest ecosystems, impacting large areas of forests every year. Fire Friend or Foe
The past decade has witnessed a sharp rise in the number of uncontrolled fires, not only in India but also across the globe. These fires have led to the loss of lives, extensive damage to forests and biodiversity, massive property loss, and displacement of people in several G20 countries. In fact, forest fires are responsible for one-third of global forest loss, with over 118 million hectares of forests destroyed between 2001 and 2021.
In April 2020, the number of fire alerts rose by 13% around the world compared to 2019, a record year for fires. Separately, countries like the USA, EU, Australia, Indonesia, and Brazil have recently experienced several mega-fires. As a matter of fact, India alone has seen a 10-fold increase in incidences of forest fires over the last two decades. While the total forest cover has increased by 1.12%, the frequency of forest fire incidents has increased by 52%. More than 36% of the country’s forest cover is estimated to be prone to frequent forest fires and more than 62% of the states to high-intensity forest fires.
Similar to other parts of the world, forest fires in India are primarily driven by human activity. Population pressures, current and historic land management practices, the use of fire as a tool, demand for forest resources, negligence, and anthropogenic climate change are some of the factors that have strongly shaped the contours of the prevailing forest regime .
The restoration of ecosystems is an important way to mitigate the risk of fires before they occur and to better recover in the aftermath. Post-fire forest restoration is, therefore, indispensable for maintaining the ecological integrity of forests and for the sustainability of affected forest landscapes. Fire Friend or Foe
Fires affect both the physical and chemical properties of soils, particularly the productive layer; changes in the physical properties lead to loss of productive soil, increased runoff, and lower underground water recharge while changes in chemical properties affect the soil’s organic matter and nutrient dynamics. Recurrent fires reduce seed sources, ultimately affecting the regeneration and succession of forest ecosystems. In North-Eastern India, the shortening of fire-associated jhum cycles has also had a detrimental effect on soil fertility. Climate change and changes in land use are predicted to increase the frequency and intensity of fires, with a global increase of extreme fires of up to 14% by 2030, 30% by the end of 2050, and 50% by the end of the century. Valuable forest resources, including carbon in the biomass, are lost due to forest fires every year, impacting the flow of goods and services from forests.
Forest fires can have devastating effects on biodiversity by destroying trees, ecosystems, and food supplies and by increasing the susceptibility of surviving animals to predation. Additionally, they can also directly affect the economic state of communities that depend on forests and non-timber forest products as a source of income. The economic losses associated with forest fires may be much greater for smallholders than for large holders considering their greater reliance on forests for a wide range of services and uses. The potential cost of forest fires in India is estimated to be over INR 1,101 crore per year.
It can be argued that forest fires can have both a negative as well as a positive impact on ecosystems. Historically, fire has played an important role in shaping the flora and fauna; fires play a key role in keeping the forests healthy, recycling nutrients, aiding in the regeneration of tree species, removing invasive weeds and pathogens, and maintaining habitats. Occasional fires can help in controlling fuel stocks that may feed larger, more destructive wildfires. However, incidences of fires have spun out of control with increasing population growth and the resultant demands on forest resources, to the point where fires no longer sustain forest health. In fact, fires are burning larger areas and fire seasons are becoming longer due to the warming climate.
As countries increasingly work to improve social-economic resilience to forest fires and other climate-related threats, there is also a need to regenerate forest-fire-affected land. The restoration of ecosystems is an important way to mitigate the risk of fires before they occur and to better recover in the aftermath. Post-fire forest restoration is, therefore, indispensable for maintaining the ecological integrity of forests and for the sustainability of affected forest landscapes.
Keeping in mind Prime Minister Narendra Modi’s vision for India’s Presidency, one that is ambitious, inclusive, decisive, and action-oriented, the Environment Climate Sustainability Working Group (ECSWG)will focus on and address the discussed issues of forest fires with an aim to drive meaningful action and accelerate ecosystem restoration in forest fire-impacted areas across the G20 countries. Considering the global nature of the rapid and alarming increase in forest fires, the Indian Presidency will encourage the active sharing of knowledge and international best practices and collaboration between the G20 countries, rooted overall in the principle of One Earth, One Family, and One Future.
