Q. What is the Qanat system, recently mentioned in the news?
Answer:
Ancient water-supply system
Notes: In response to severe water shortages in dry regions of Africa, the ancient "qanat system" is proposed as a solution. Originating in arid areas worldwide, this water-supply system channels mountain water through sloping tunnels to address limited water supplies. Known by various names, such as "foggara" and "falaj," qanats have been used for centuries in regions like North Africa, the Middle East, and Asia. This gravity-based system, requiring no electricity, offers sustainability, minimal evaporation, and widespread irrigation potential, fostering social cohesion.
