Breakthroughs in the production and productivity of wheat and rice in the sixties and of cotton recently have been much appreciated, but similar advances in maize have gone largely unnoticed and unsung. Maize output has soared in the past 10 years from a mere 12 million tonnes in 2000-01 to over 21 million tonnes in 2010-11. This increase can largely be attributed to a surge in crop productivity rather than...

From the Middle East to Madagascar, high prices are spawning land grabs and ousting dictators. Welcome to the 21st-century food wars. In the United States, when world wheat prices rise by 75 percent, as they have over the last year, it means the difference between a $2 loaf of bread and a loaf costing maybe $2.10. If, however, you live in New Delhi, those skyrocketing costs really matter: A doubling in...

Punjab's attempts at diversification from water-guzzling paddy hasn’t made much headway. With looming desertification and reverse flow from water-logged blocks having brackish groundwater to areas where the groundwater table is fast depleting, the need to diversify has been underlined since long. Even in a lean monsoon year (2009), there was a record harvest of the crop. Its acreage did not fall even last year when a major part of the paddy...

The dun wheat field spreading out at Ravi P. Singh's feet offered a possible clue to human destiny. Baked by a desert sun and deliberately starved of water, the plants were parched and nearly dead. Dr. Singh, a wheat breeder, grabbed seed heads that should have been plump with the staff of life. His practiced fingers found empty husks. “You're not going to feed the people with that,” he said. But then, over...

The world population is estimated to reach nine billion by 2050. The Food and Agriculture Organisation (FAO) estimates that global food production needs to increase 70 per cent by 2050 compared to average 2005-07 levels to feed the rising global population. Clearly, a large part of the consumption will happen in India and China; which would require an additional 1.6 billion hectares of land to be brought into cultivation compared to...
