What is Karewa?

  • In the Kashmiri dialect, the term Karewa means “elevated table land”. “Vudr” is the local name for Karewas in Kashmiri language.

    • 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.
    • Karewas are the thick deposits of glacial clay and other materials embedded with moraines. These are unconsolidated lacustrine deposits. Lacustrine means “associated with lakes”.

    How were they formed in Kashmir valley?

    • Kashmir valley resides between the Great Himalayas and the Pir Panjal ranges of the Kashmir Himalayas. In earlier times, when the upliftment of the Pir Panjal ranges happened, the flow of the river had stopped.
    • As a result, the whole of Kashmir valley became a large lake. Slowly, the glacial deposits have accumulated here in this lake. Thus creating a large lacustrine plain.
    • Later on, the water drained away and these unconsolidated deposits remained there. These unconsolidated gravel and mud deposits are known as Karewa formation.

     

    Economic significance of Karewas:

    • Karewa deposits have different soil and sediments such as sand, clay, silt, shale, mud, lignite and losses. Hence, these are very useful for agricultural and horticulture activities.
    • Karewa formations are useful for the cultivation of Zafran is a local variety of Saffron in Kashmir valley. These are also important for the cultivation of almond, walnut, apple, and orchards.
