Uttarakhand Wildfires: Threat To Glaciers

Why in News?

In Uttarakhand, the wildfires have taken a toll on the region's forests. From November 2023, 1,107 hectares of forest cover have succumbed to 886 separate incidents of wildfires, sparking concerns about the profound impact on the local ecosystems.

Key Points

  • The Forest Survey of India (FSI) has issued multiple fire alerts to Uttarakhand, emphasising the severity of the ongoing crisis.
  • A former scientist from the Wadia Institute of Himalayan Geology, sheds light on the increased concentration of Black Carbon in the atmosphere, particularly during summer due to forest fires, exacerbates glacier melting and disrupts the delicate balance of the entire ecosystem.
  • A recent study conducted by the World Bank underscores the role of black carbon in accelerating glacier melt.
    • According to the report, the accumulation of black carbon not only diminishes the reflectance of glacier surfaces, leading to increased absorption of solar radiation, but also elevates air temperatures, further accelerating glacier retreat.
  • The World Meteorological Organisation (WMO) warns of accelerated glacier retreat in the Himalayas and heightened risks of natural disasters like Glacial Lake Outburst Floods.
    • Their recent study states the need for concerted efforts to mitigate the impacts of black carbon emissions and safeguard the fragile ecosystems of the Himalayan region.

Wadia Institute of Himalayan Geology (WIHG)

  • The Wadia Institute of Himalayan Geology is an autonomous research Institute of the Department of Science & Technology.
  • Established in June, 1968 as a small nucleus in two rooms of the Botany Department, Delhi University, the Institute was shifted to Dehradun during April, 1976.

Glacial Lake Outburst Flood (GLOF)

  • It is a type of catastrophic flood that occurs when the dam containing a glacial lake fails, releasing a large volume of water.
  • This type of flood is typically caused by rapid melting of glaciers or the buildup of water in the lake due to heavy precipitation or the inflow of meltwater.
  • In February 2021, Chamoli district in Uttarakhand witnessed flash floods which are suspected to have been caused by GLOFs.
  • Causes:
    • These floods can be triggered by a number of factors, including changes in the volume of the glacier, changes in the water level of the lake, and earthquakes.
    • According to NDMA (National Disaster Management Authority), glacial retreat due to climate change occurring in most parts of the Hindu Kush Himalayas has given rise to the formation of numerous new glacial lakes, which are the major cause of GLOFs.

Uttarakhand Forest Fires Halt Air Services

Why in News?

Air services to Pithoragarh and Munsiyari towns in the border district were halted for the due to low visibility at the Naini-Saini airport caused by smoke from the forest fires.

Key Points

  • Visibility in the vicinity of the airport was below 1000 meters, whereas air traffic requires a minimum of 5000 meters of visibility to operate safely.
    • Apart from the Saur valley, there are forest fires spreading in Quirala valley of Champawat and the forests of Lohaghat, Jhoolaghat, and Gaurihat.
    • According to healthcare professionals at community and primary health centers in different locations within the district, a growing number of patients are visiting hospitals with concerns of breathing difficulties and eye irritation.
  • Naini Saini Airport otherwise called Pithoragarh Airstrip is situated in Pithoragarh, Uttarakhand. The airstrip was built in 1991 for authoritative use and got ready for the operations of the Dornier 228 sort flying machine.
