Forest Fires in India: Causes, Impact and UPSC Notes (UPSC Environment)

Study Notes · Environment & Ecology · General Studies · GS III

UPSC guide to forest fires in India: natural and anthropogenic causes, impact on biodiversity and carbon sequestration, FSI fire alert system and climate adaptation.

Forest fires are not always catastrophic. Small, controlled fires in the form of prescribed burning are actually useful and essential for healthy forest regeneration: they clear the annual buildup of litter, reduce the risk of larger catastrophic fires, improve silvicultural opportunities, increase forage, enhance wildlife habitat and support biodiversity. But uncontrolled forest fires are one of India’s fastest-growing environmental threats, destroying biodiversity, releasing stored carbon and damaging livelihoods. The Forest Survey of India reported over 2.23 lakh fire points in 2024, up sharply from previous years. For UPSC aspirants, forest fires are a key GS Paper III theme on environment, disaster management and climate change.

Why forest fires matter

Forests in India account for about 24 percent of the land area. They are major carbon sinks, biodiversity reservoirs, watersheds and livelihood sources. Fires not only damage these services but also release greenhouse gases that accelerate climate change, which in turn increases future fire risk – a classic positive feedback loop.

Causes of forest fires

Forest fires are caused by both natural and anthropogenic factors.

Forest Survey of India Fire Alert System

The Forest Survey of India, Dehradun, runs India's main forest fire monitoring system.

Major fire seasons are March to May in the Himalayas and central India, and October to December in parts of the Western Ghats and North-East.

Biodiversity change

Fire alters species composition. In the Himalayas, fires have made the environment less favourable for oaks to regenerate and more favourable for chir pine to dominate, creating a self-reinforcing fire cycle. In grasslands, repeated fires favour fire-adapted grasses over fire-sensitive woody species.

Reduced soil moisture

Fires kill the plants that hold moisture and create hot, dry conditions that increase future fire probability.

Reduced water infiltration

Heat-induced chemical and physical changes in the upper layer of soil create water-repellent (hydrophobic) layers, reducing infiltration and increasing surface runoff.

Enhanced global warming

Microclimate change

Soil erosion

Intense fires heat the soil at depths of 7 to 10 cm. The affected soil loses its water-holding capacity and becomes vulnerable to erosion during subsequent rains.

Flooding

Water-repellent soils and vegetation cover loss give rise to higher chances of flash floods during the next heavy rainfall.

Air quality and public health

Forest fire smoke contributes to particulate matter pollution. In high-fire seasons, fine particulate matter in the Doon valley, the Uttarakhand hills and North-East cities rises noticeably.

UPSC Relevance

Prelims focus

Mains focus (GS III)

Typical question framings evaluate the causes of increasing forest fires, climate change impacts, the role of community-based fire management, and the economic value of chir pine needle utilisation. Strong answers cite FSI data, NAP on Forest Fires, specific disasters like 2024 Uttarakhand, and international frameworks.

Forest fires connect to SDG 13 (climate action), SDG 15 (life on land), the Sendai Framework for Disaster Risk Reduction, India's updated NDCs after COP29, the Paris Agreement's forest carbon commitments, the Forest (Conservation) Amendment Act 2023, the Biological Diversity Amendment Act 2023 and the Wildlife (Protection) Amendment Act 2022.
