The world is planting a vigorous new crop: “agro-pessimism”, or fear that mankind will not be able to feed itself except by wrecking the environment. The current harvest of this variety of whine will be a bumper one. Natural disasters—fire in Russia and flood in Pakistan, which are the world’s fifth- and eighth-largest wheat producers respectively—have added a Biblical colouring to an unfolding fear of famine. By 2050 world grain output will have to rise by half and meat production must double to meet demand. And that cannot easily happen because growth in grain yields is flattening out, there is little extra farmland and renewable water is running short.The world has been here before. In 1967 Paul Ehrlich, a Malthusian, wrote that “the battle to feed all of humanity is over… In the 1970s and 1980s hundreds of millions of people will starve to death.” Five years later, in “The Limits to Growth”, the Club of Rome (a group of business people and academics) argued that the world was running out of raw materials and that societies would probably collapse in the 21st century.
A year after “The Limits to Growth” appeared, however, and at a time when soaring oil prices seemed to confirm the Club of Rome’s worst fears, a country which was then a large net food importer decided to change the way it farmed. Driven partly by fear that it would not be able to import enough food, it decided to expand domestic production through scientific research, not subsidies. Instead of trying to protect farmers from international competition—as much of the world still does—it opened up to trade and let inefficient farms go to the wall. This was all the more remarkable because most of the country was then regarded as unfit for agricultural production.
The country was Brazil. In the four decades since, it has become the first tropical agricultural giant and the first to challenge the dominance of the “big five” food exporters (America, Canada, Australia, Argentina and the European Union).
Even more striking than the fact of its success has been the manner of it. Brazil has followed more or less the opposite of the agro-pessimists’ prescription. For them, sustainability is the greatest virtue and is best achieved by encouraging small farms and organic practices. They frown on monocultures and chemical fertilisers. They like agricultural research but loathe genetically modified (GM) plants. They think it is more important for food to be sold on local than on international markets. Brazil’s farms are sustainable, too, thanks to abundant land and water. But they are many times the size even of American ones. Farmers buy inputs and sell crops on a scale that makes sense only if there are world markets for them. And they depend critically on new technology. As the briefing explains, Brazil’s progress has been underpinned by the state agricultural-research company and pushed forward by GM crops. Brazil represents a clear alternative to the growing belief that, in farming, small and organic are beautiful.
