Wake river basin project

• Caused by humans due to over irrigation (salinisation) and no management of the wells (too much water being drawn from aquifilter)
• Caused physically due to hot climates (regularly over 50°C) and lack of rainfall (less than 250 mm per year)
• Response: Taankas

  Underground storage systems that collect surface water from roofs

  3m in diameter and 3-4m deep

  Sustainable (uses rainwater)
• Response: johads

  Small earth fans to catch rainwater

  Help raise water tables (underground) by up to 6m

  5 rivers that used to dry up following the monsoon now flow throughout the year

  Sustainable (intermediate technology)
• Response: pats

  Irrigation channels that transfer water into the fields

  A small dam called a bund diverts the water from the stream towards the fields

  Bunds are made from stones and lined with leaves to make them waterproof
