Crop yields lag demand
28 Sep 2004
Global crop yields must soar in coming years or the world will face a grain shortage, Professor Monkombu Swaminathan, one of the pioneers of the green revolution and a winner of the World Food Prize, told a crop conference in Brisbane. Swaminathan said the world was going through a major decline in yield improvements. Prof Swaminathan said crop yield, the rate of production per hectare, had grown strongly through much of the 20th century on the back of scientific breakthroughs, new breeds and the advent of improved farming systems. But yield improvements were now slipping to the point that production of major crops may not be able to meet demand in coming years.
