In which Indian state is bamboo drip irrigation system a very old practice?

  1. A.Chattisgarh
  2. B.Meghalaya
  3. C.Telangana
  4. D.Maharashtra

Correct answer

B. Meghalaya

Explanation

The correct answer is B, Meghalaya. Bamboo drip irrigation is a two-hundred-year-old practice of the Khasi and Jaintia hills of Meghalaya. Water from a hill spring or stream is led through split bamboo pipes, channels and diversion sections down the slope, and the flow is cut down stage by stage until the last narrow pipe drips water right at the root of the plant. Around eighteen to twenty litres a minute entering the system come out as twenty to eighty drops a minute at the plant. It is used mainly for betel leaf and black pepper grown along with areca nut, needs no pump or electricity, and is studied as a model of water harvesting on steep ground where channels cannot be dug. Option A is wrong because Chhattisgarh relies on tank and canal irrigation. Option C is wrong because Telangana depends on tanks, borewells and lift irrigation. Option D is wrong because Maharashtra is known for modern plastic drip irrigation, not the bamboo system. Exam tip: bamboo drip - Meghalaya, zabo - Nagaland, apatani - Arunachal Pradesh, kuhl - Himachal Pradesh, ahar-pyne - Bihar.

Correct answer: C. 2 and 3 only

Himalayan rivers are perennial, so statement 1 is wrong, while statements 2 and 3 are correct. Himalayan rivers such as the Ganga, Indus and Brahmaputra rise from glaciers and snowfields and also get monsoon rain, so they flow all year round, including in winter.

All three statements about latitude are true. Latitude decides how directly the Sun's rays strike a place, so temperature, rainfall and the type of vegetation change from the equator towards the poles, from hot, wet rainforests to cold tundra.
