Forest loss across India’s Himalayan states accelerating as climate change, infrastructure expansion and extreme weather increase risks to biodiversity, water security and millions of people dependent on fragile mountain ecosystems.
Data shows decline across Himalayan states raising alarms over climate, Biodiversity and water security.
Forest cover in India’s Himalayan region has declined by more than 350 square kilometres in just two years raising fresh concerns as rising temperatures and extreme weather intensify risks across one of the world’s most fragile mountain ecosystems.
According to 18th India State of Forest Report 2023 in the Indian Himalayan Region dropped from 15,427 square kilometres in 2021 to 15,075 square kilometres in 2023. The loss of 352 square kilometres represents a decline of more than two percent in a short span of time.
The region stretches across 13 states and union territories including Jammu and Kashmir, Ladakh, Himachal Pradesh, Uttarakhand, Sikkim, Assam and Tripura and is home to millions of people who depend on forests for livelihoods, water sources and protection from natural hazards.
Despite its ecological sensitivity the Himalayan belt is witnessing rapid infrastructure expansion. Road construction, hydropower projects and urban development are accelerating across several states particularly in the northeast and in Uttarakhand and Himachal Pradesh.
In Uttarakhand projects such as the Gangotri Highway expansion and the Rishikesh Bypass have triggered debate. The Gangotri highway expansion alone is expected to require the felling of around 7,000 trees raising concerns about long-term environmental damage in a landslide-prone region.
Geologists have long warned that Uttarakhand is highly vulnerable to landslides. Forests play a critical role in stabilising slopes and maintaining soil structure. Their removal increases the likelihood of disasters as seen in recent events such as land subsidence in Joshimath and landslides in Uttarkashi which have heightened risks for local communities.
At the same time climate trends are worsening the situation. Data from India’s Earth Sciences Ministry shows that the country’s average temperature rose by about 0.7 degrees Celsius between 1901 and 2018. The intensity of extreme rainfall has also increased significantly with events exceeding 150 mm in 24 hours rising by nearly 75 percent between 1950 and 2015.
Satellites tracking the Himalayan landscape over the past two decades have revealed shifting vegetation patterns in Uttarakhand highlighting both the resilience of mountain ecosystems and growing environmental pressures from climate change, deforestation and pollution.
A team of researchers from the Aryabhatta Research Institute of Observational Sciences in Nainital along with national and international collaborators analysed satellite data from 2001 to 2022 to understand how vegetation in the state has responded to changing climate and human activity.
Experts warn that the combined impact of deforestation and Climate Change could have far-reaching consequences. Forests help regulate rainfall, reduce soil erosion and sustain biodiversity. Their decline is likely to increase the frequency of floods, landslides and other climate-related disasters.
Tree cover across India’s ecologically fragile Himalayan belt has declined by 2.27 percent in just two years according to figures cited by the Union government a development that underscores mounting environmental stress in one of the planet’s most sensitive mountain ecosystems.
The situation highlights a growing tension between development and environmental protection in the Himalayan region. Scientists and environmentalists are calling for more sustainable planning and stricter safeguards to prevent further ecological damage.
Without urgent action the accelerating loss of forest cover coupled with rising temperatures could leave the Himalayan ecosystem and the millions who depend on it facing an increasingly uncertain and risky future.
