  • Indus Basin Irrigation System (IBIS)
    • What is it?
      • The largest continuous irrigation scheme in the world
      • Three large dams and over a hundred smaller dams regulate water flow
      • Link canals enable water to be transferred between rivers
      • Over 1.6 million km of ditches and streams provide irrigation for Pakistan's agricultural land
      • Smaller canals distribute the water across the countryside
    • Advantages of the scheme
      • Improves food security for Pakistan, making 40% more land available for cultivation
      • Irrigation has increased crop yields
      • Diets have improved as a greater range of food products is available
      • HEP is generated by the large dams
    • Disadvantages of the scheme
      • Some farmers take an unfair share of the water
      • Poor irrigation techniques mean water is wasted salinisation (increased saltiness) can damage the soil
      • Population growth will increase the demand for water
      • High costs to maintain reservoir capacity
