karewas

In News 

  • Kashmir’s highly fertile alluvial soil deposits called ‘karewas’ are being destroyed in the name of development, much to the peril of local people.
Details
  • These plateaus are 13,000-18,000 metre-thick deposits of alluvial soil and sediments like sandstone and mudstone.
  • This makes them ideal for cultivation of saffron, almonds, apples and several other cash crops.
  • Kashmir saffron, which received a Geographical Indication (GI) tag in 2020 for its longer and thicker stigmas, deep-red colour, high aroma and bitter flavour, is grown on these karewas.
  • The fertility of these patches is believed to be the result of their long history of formation.
  • When formed during the Pleistocene period (2.6 million years to 11,700 years ago), the Pir Panjal range blocked the natural drainage in the region and formed a lake spanning 5,000 sq km (roughly three times the size of Delhi).
Formation 
  • Over the next few centuries, the water receded, making way for the valley and the formation of the karewas between the mountains.
  • Today, the karewa sediments not only hold fossils and remnants of many human civilisations and habitations, but are also the most fertile spots in the valley.
About Karewas 

  • In the Kashmiri dialect, the term Karewa means “elevated table land”.
  • Firstly, this term was used by Godwin Austin in 1859 and later on by Lydekker in 1878 for unconsolidated to semi-consolidated sand clay conglomerate sequence.
  • “Vudr” is the local name for Karewas in Kashmiri language.
  • Karewas are the thick deposits of glacial clay and other materials embedded with moraines. These are unconsolidated lacustrine deposits. Lacustrine means “associated with lakes”.
