Paddy Cultivation Revisited: Drought-proofing

Filed under: Economics,Punjab,Technology — loggers @ 5:03 pm

After touring Punjab, we had written (1,2) about the negative externalities associated with paddy cultivation. Normally, 3,000 — 5,000 litres of water are needed to produce a kilogramme of rice. We inferred that this level of water usage is unsustainable (this is reflected by a depleting water table). In a column in the Business Standard, Surinder Sud covers a potential solution to the problem in the form of  “aerobic rice cultivation”.

This is exactly the kind of technological innovation that is needed to curb the painful wastage of water associated with growing rice in India. According to Sud, the water saved using this technique can equal a fourth of all the water used in Asia. It seems that China had the method figured out in 2002 and that Pakistan was contemplating a similar practice in 2005.

  1. Dear Naman,

    In the book, ‘One Straw Revolution’, Masnobu Fukoka talks about his way of farming which does not need tilling and flooding… and doesnot use fertilizers and pesticides – yet produces the highest yields in Japan – is a very interesting concept. I believe this was tried out in Hoshangabad (M.P., near Bhopal)
