Climate change is causing glaciers to retreat across much of the Himalaya, leading to a rapid shift of the vegetation cover to higher altitudes. However, the rate of vegetation shift with respect to glacier retreat, climate change, and topographic parameters is not empirically quantified. Using remote sensing measurements, we estimate (a) the rate of glacier-ice mass loss, (b) the upward vegetation line shift rate, (c) regional greening trends, and (d) a relationship between the factors influencing the greenness of the landscape and vegetation change in the Himalaya.

Himalayan glaciers have long been the focus of glaciologists across the world while trying to understand the contrasting patterns of elevation and mass changes. However, with limited number of ground observations, a comprehensive assessment of mass balance on a regional scale still remains elusive. Using the synoptic coverage of remote sensing data, we estimate a detailed spatial variation of glacier ice thickness change in the Central Himalaya of Uttarakhand using geodetic method, on a catchment scale.

Article Synopsis
  • Large-scale forest clear-cut identification using remote sensing techniques is crucial due to rising deforestation rates.
  • The study utilizes multi-temporal ALOS-2/PALSAR-2 SAR data alongside Landsat-8 optical data to monitor clear-cuts in Indian tropical forests, particularly in Teak plantations.
  • It finds that cross-polarized backscatter and entropy are key indicators for assessing clear-cuts, leading to an accurate classification of these regions for improved forest management.
