There has been a tremendous increase in food grain production mainly through developments in crop science and production technology over the last four decades. However, there is increasing concern as to whether development in science and technology will be adequate to meet the increasing demands of the growing population. To produce and provide food needed for those additional 77 million people annually is possible but an uphill task. The lion’s share (75 to 80%) of future food production growth will have to come from productivity increases. Further challenge would be not only to meet the food requirement from limited resources but it has to be produced in a changed demand structure in a most sustainable manner keeping in view the fragile environments especially in the resource poor countries of Asia and Africa.
