We all know India has a huge competitive advantage — we have the largest arable land, focused sunshine, sensible utilisation of water in 30% of land. The question is what should we do to make the US market — the most difficult market in the world — accept our produce. For that, we need traceability. It is a simple technology, which we are giving the farmers. It needs certification and verification processes — to us it is like a process plant. You can then get the output, sort it and grade it.
