At first glance, Giuseppe Oglio's farm near Milan looks like it's suffering from neglect. Weeds run rampant amid the rice fields and clover grows unchecked around his millet crop.
Mr. Oglio, a third generation farmer eschews modern farming techniques - chemicals, fertilizers, heavy machinery - in favour of a purely natural approach. It is not just ecological, he says, but profitable, and he believes his system can be replicated in starving regions of the globe.
Nearly 8,000 km away, in laboratories in St. Louis, Mo., hundreds of scientists at the world's biggest seed company, Monsanto, also want to feed the world, only their tools of choice are laser beams and petri dishes.
Monsanto, a leader in agricultural biotechnology, spends about $2 million a day on scientific research that aims to improve on Mother Nature, and is positioning itself as a key player in the fight against hunger.
The Italian farmer and the U.S. multinational represent the two extremes in an increasingly acrimonious debate over the future of food.
Everybody wants to end hunger, but just how to do so is a divisive question that pits environmentalists against antipoverty campaigners, big business against consumers and rich countries against poor.
The food fight takes place at a time when experts on both sides agree on one thing - the number of empty bellies around the world will only grow unless there is major intervention now.
A combination of the food crisis and the global economic downturn has catapulted the number of hungry people in the world to more than one billion. The United Nations says world food output must grow by 70 per cent over the next four decades to feed a projected extra 2.3 billion people by 2050.
International leaders are gathering in Rome next week for the U.N. Food and Agriculture Organization's World Summit on Food Security and will hear competing arguments over how best to tackle the problem. One of the fiercest disputes will be over the relative importance of science versus social and economic reforms to empower small farmers to grow more with existing technology.
Much of Europe has moved away from an agricultural system of small farms to mass commercial farming, but Italy still retains a base of family farmers who produce everything from olives to mozzarella cheese.
Mr. Oglio is one of them. A charismatic 40-year-old, he dropped out of an agricultural school after growing disillusioned with the farming methods being taught there. Today, he lets nature run its course as he grows cereals and legumes on his small family farm in Belcreda di Gambolo, about 20 miles (30 km) southwest of Milan.
He does not use any chemical, or even natural fertilizers or pesticides. He does not weed his fields. "All you need to do is observe nature, listen to it, do what nature suggests and it will take care of everything," he said.
His fields, in a low-lying plain that has a long history of growing rice used for risotto, replicate patterns found in nature. For example, clover and millet grow together, feeding each other with necessary minerals.
Mr. Oglio said his farm is eco-sustainable. He has slashed operating costs by eliminating expensive commercial products like herbicides and by reducing the use of agricultural machinery to a minimum. Such cheap and low-maintenance farming could be adopted in Africa and other regions hit by poverty and hunger, he said.
"Natural farming will not save the world. But it can feed poor families," he said.
But it's unlikely it can do so on the scale that most experts believe is necessary. And therein lies the rub. Affluent consumers may prefer the Oglios of the world to the Monsantos, but their skittishness about high-tech agriculture is making it more difficult to grapple with the mounting crisis over the lack of food.
The last time the world faced such dire predictions of famine was before the Green Revolution of the 1960s and 1970s, when countries like India and China transformed their agricultural systems to become self-sufficient in food. They did so by harnessing plant-breeding technology to raise yields on rice, wheat and other staple crops.
Through massive state investment in hybrid rice, China, the world's most populous country, raised its yields from two tonnes per hectare in the 1960s to more than 10 tonnes per hectare by 2004. Chinese scientists seek further gains - 13.5 tonnes per hectare by 2015, according to the International Food Policy Research Institute (IFPRI), which cites China's rice program as one of the true success stories in agricultural development in a study out this week (Nov. 12) called "Millions Fed."
