Irrigation system of Pakistan
Pakistan relies on four main irrigation systems: 1) Intake structures and pumping stations draw water from rivers, lakes, dams and barrages, providing 142 million acre-feet of water annually. 2) A conveyance system of canals, distributaries and minors distributes the water. 3) Surface, subsurface, sprinkler and drip irrigation are used to apply water to fields. Surface irrigation methods include basin, furrow and border irrigation. Subsurface irrigation applies water to ditches beneath the soil surface. Sprinkler and drip irrigation create artificial rainfall or distribute water slowly to plant roots.
