A second science-based Green Revolution is needed for increasing rice productivity as the health of rice-based systems determines the fate of Indian agriculture, Robert S. Zeigler, director general, International Rice Research Institute (IRRI), Philippines, said here on Friday.

At a seminar on “Rice Research Innovations for Addressing Global Food Security in a Changing Climate” held at Tamil Nadu Agricultural University in connection with the Centenary Year of the Paddy Breeding Station, he said that this revolution would be made possible by tapping innovations in genetics, molecular biology and plant physiology, and linking soil biology and chemistry.
