I think 'Loan' is 'Money' which is not needed by farmers. They are commiting suicide because they could not produce the crops ventured by them while taking loan (there would various reasons for such failures). They need the field i.e. 'Zamin' to continue venturing and trying their speculations with nature. I have heard peasants are not highly educated (may be I am wrong) Therefore, this is the key to all of their problems. If they become highly educated, then they would hardly fail - that would be termed as 'Green Revolution version 2...3...4....n'. However, as a FIRST STEP presently highly educated section of the society (INDIA as a WHOLE) to be approached by the GOVERNMENT to find out the RIGHT TOOL to survive during such failures and also consistently keep monitoring the data on day-in day-out basis. You would see the difference 'Doodh ka doodh aur Paani ka paani'. Thank you for providing me an opportunity to write on this subject.
