For First Time in Many Years, No Rhinos Poached in Assam in 2022

  • Assam Chief Minister Himanta Biswa Sarma announced that no rhinos were poached in the state in 2022. Special DGP G P Singh posted data that showed last year was the first since at least 2000 in which there were no incidents of rhino poaching in Assam.
  • Rhinos were poached for their horns that fetch big money because of their supposed medicinal value.
  • Before 2022, no poaching of rhinos was last reported in 1977. Officials credited sincere, concerted and coordinated efforts of the state's forest and police departments for zero poaching in 2022.

South Asian Black Carbon Aerosols Increase Glacial Mass Loss over Tibetan Plateau

  • According to a new study, black carbon aerosols have indirectly affected the mass gain of the Tibetan Plateau glaciers by changing long-range water vapour transport from the South Asian monsoon region.
  • The South Asia region adjacent to the Tibetan Plateau has among the highest levels of black carbon emission in the world.
  • Black carbon aerosols are produced by the incomplete combustion of fossil fuels and biomass, and are characterised by strong light absorption.
  • Many studies have emphasised black carbon aerosols from South Asia can be transported across the Himalayas to the inland region of the Tibetan Plateau.
  • Researchers noted that black carbon deposition in snow reduces the albedo of surfaces -- a measure of how much of Sun's radiations are reflected -- which may accelerate the melting of glaciers and snow cover, thus changing the hydrological process and water resources in the region.

The 'Enigmatic' Peat Bog Seeking Worldwide Recognition

  • A vast area of peat bog in Scotland's Flow Country could become one of UNICCO's newest World Heritage sites.
  • This land was prepared for large blocks of commercial forestry, which included the planting of millions of non-native trees.
  • Flow Country is home to a diverse range of wildlife including birds, mammals and plants.
  • Flow Country contains the most intact and extensive raised bog system in the world.
  • This expanse of moors, moors, pools, lochs, hills and mountains covers much of Caithness and Sutherland in the North Highlands.
  • It's about 50 miles wide – about the distance from Glasgow to Edinburgh – and covers almost a million acres of land.
  • The bogs, which have been growing for 10,000 years, are formed by layers of wet mosses and other plants as they die.
