Millions of tiny black beetles attack the greenhouse vegetables of a Greek farm each spring. They suck the stems of the lettuce; they bore into the tomatoes and leave the cucumbers bleeding. They transmit viruses, and leave the fruit vulnerable to fungi.
Immediate action is needed. The farmer, Theofanis Kapelos, arrives with his van, unloads five plastic bottles and heads toward the greenhouse. He dons a pair of thick plastic gloves, opens the first bottle and pours its contents –a grainy white substance– on the leaves and fruits.
Five days later, the black beetles have disappeared. However, neither dead insect bodies, nor repellent smells linger in the greenhouse. The vegetables slowly recover from their wounds-but now thousands of white wasps are hovering over them. This cure is not the result of a chemical pesticide, but an organic one. The plastic bottles contained minute white eggs of wasps that hatched from their eggshells, ate the beetles and rescued Kapelos’ organic crop.
For Kapelos and other organic farmers, this is the future: a farming method that produces healthy and safe food without use of chemical pesticides and fertilizers. Can this type of farming sustain the world’s expanding population? Kapelos hesitates to answer. Even for governments and academics this is a point of contention.
Organic farming has been around since the beginning of the 20th century, when environmentally friendly ways of farming rose in Northern Europe. However, it was not until the 1980s that organic produce hit the world market as a response to consumers’ demands for healthy and pure nutritional products. Organic farming, which currently occupies only 0.3 percent of global agricultural land, is a system that excludes the use of chemicals in addition to preserving soil nutrients and water supplies for future generations. This type of farming also preserves the natural reproductive cycles, in contrast to conventional agriculture which accelerates the natural pace of plant growth using hormones.
Organic farming was originally formulated as an ideology, but today’s global problems –such as climate change and population growth– require agricultural pragmatism and flexibility, not ideology, argued Anthony Trewavas, a professor of plant biology at the University of Edinburgh, in a 2001 Nature commentary. “Conventional agriculture is a diverse set of technologies using the best available knowledge, whose ultimate goal is the safe efficient provision of foods in abundance and at lower price,” Trewavas wrote.
However, according to organic farming advocates, “only a global conversion [to this alternative system] would serve as a solution to environmental pollution and soil depletion,” says Barbara Haumann, a press secretary at the Organic Trade Association, in Greenfield, Massachusetts.
The debate over whether organic farming could sustain the world’s rapidly growing population is heating up. The United Nations estimates that the world population will increase from 6.6 billion in 2008 to 9.2 billion by 2050, demanding farming methods that produce high yields in a short period of time. These farming methods, usually applied in conventional and genetically engineered crops, deplete soil nutrients and pollute groundwater aquifers.
“Agrochemical inputs [used in conventional farming] have had very negative impacts on the environment, but also on the health of people and rural communities,” says Ivette Perfecto, a professor of field ecology at the University of Michigan in Ann Arbor. Although some critics raise human health concerns –mostly related to hormone and pesticide use– no human health effects have been scientifically documented.
Nevertheless, those health concerns, in addition to global environmental problems such as poor air quality, acid rain and rising temperatures, are now pushing society towards more sustainable agricultural systems that will not burden the already fragile environment.
But can organic farming really feed the world?
Even the definition of what constitutes organic farming is under debate. Each country has set its own regulations for how soil, water, plants and animals should be treated. However, the International Federation of Organic Agriculture Movements–an organization established in 1972 to unite the organic movement and promote the worldwide adoption of organic farming– has set down four main principles of organic agriculture: health, ecology, fairness and care.
The principle of ecology, for example, requires the application of mild techniques, such as leaving the soil uncultivated for a few seasons so that its nutrients can recover. Although organic farming that applies such practices protects soil’s fertility and conserves natural resources, it also “requires larger tracts of land in order to produce the same yields,” says Christina Giourga, a professor of environmental agriculture at the University of the Aegean in Mytilene, Greece. Norman Borlaug, an agronomist and winner of the Nobel peace prize for fighting world hunger, said in an interview with Reason magazine in April 2000: “If all agriculture were organic, people would have to increase cropland area dramatically, spreading out into marginal areas and cutting down millions of acres of forests.”
While organic farming may require more land to produce the same amount of produce as conventional agriculture, Indur Goklany, an environmental policy analyst based in Washington D.C., sees this as a positive factor. In a 2002 letter to Science, Goklany wrote that using more land to yield the same amount of product as conventional agriculture secures a non-intensive organic farming that maintains the cropped land’s fertility and biodiversity for longer time. Michael Bomford, director of sustainable vegetable production research at the Kentucky State University in Frankfort, argues that “we worry about how we can feed the human population and we are not thinking about whether the planet can support us.” He explains that people are not separate from the other million species of the planet; if they use all the natural resources, all species including humans will be in danger of extinction. Bomford argues that organic agriculture is an attempt to create a sustainable system that can persist for the long term.
However, under pressure to produce high yields, some countries disregard the principle of ecology and do not apply these practices. Instead, organic farming in these countries often means simply avoiding the use of chemicals in the fields. The result is that organic farming can produce yields equal to conventional farming, according to Catherine Badgley, a geology researcher at the University of Michigan. Similarly, Joshua Posner and his co-workers at the University of Wisconsin in Madison agree in a 2008 Agronomy Journal article that organic crops produce 90 percent as much product as conventional ones.
Thanasis Kizos, a lecturer of rural geography at the University of the Aegean, claims that this type of intensive organic farming can feed the world as well as conventional agriculture does, but at the same time it generates environmental problems and disturbs the agro-ecosystem’s balance.
Assessing whether organic farming can feed the world requires more than a mere calculation. Simply dividing the total food supplies by the world’s population is not enough to ensure that everyone will have equal access to these food supplies.
The Food and Agriculture Organization of the United Nations (F.A.O.) reports on its website: “Food security is not only a question of the ability to produce food, but also of the ability to access it.” Current world food supplies are more than sufficient to provide the entire global population with the recommended minimum of 1,900 calories a day, according to Mathew Tyler, a campaigner for the Organic Consumers Association in Finland, Minnesota. However, more than 850 million people worldwide are undernourished, according to the F.A.O. Perfecto agrees that “it is not an issue of how much food is being produced, but it is an issue of the distribution of that food.”
A recent report by the United Nations International Fund for Agricultural Development (I.F.A.D.) concludes that organic farming can reduce poverty and hunger in developing countries because organic products grow without high-priced chemical pesticides and fertilizers. I.F.A.D. also argues that organic farmers will not be as dependent upon agro-industries as farmers of conventional crops are.
However, Craig Meisner, a professor of soil management at Cornell University in Ithaca, New York, says “we cannot assume that organic manures are cheap and available to all.” Meisner argues that compost, a natural fertilizer made from plant biomass and cow dung, is not always available in developing countries. People need these natural resources for other purposes, such as cattle feed and cooking fuel. Borlaug agrees: “Even if you could use all the organic material that you have –animal manures, human waste and plant residues–and get them back on the soil, you couldn’t feed more than four billion people.” Because of the shortage of organic material, says Kizos, “developing countries’ dependence upon agro-industries will not cease.”
Similar to developing countries, low-income communities of developed countries sometimes lack adequate access to food. According to Nikolaos Beopoulos, a professor of rural sociology at the University of Athens in Greece, organic food is more expensive than conventional one because it costs more to produce, is more labor intensive and carries a higher risk of crop failure. One solution could be to cut transportation and handling costs by locally distributing organic products. “A closer relationship between farmers and consumers can push organic food prices down,” Beopoulos adds.
However, some agribusiness industries such as Monsanto Company -a major producer of genetically modified foods- are dismissive of organic farming. Vivian Browses, a spokesperson for Monsanto says that “consumers of organic food are paying for the idea” that organic food is superior. And Borlaug adds that “if people want to believe that the organic food has better nutritive value, it’s up to them to make that foolish decision.”
But, who can guarantee that organic farming is environmentally friendly and organic food is safe and healthy?
“There is very little science” in organic farming, according to a House of Lords Committee on European Communities’ report published in 1999. Scientist seem to agree that there is not enough research that shows that organic foods provide better nutrition. Beopoulos says that “organic farming methods are environmentally friendly, but we are not sure yet about its results.”
Nevertheless, the answer to whether organic products can feed the world might not be black or white, but different shades of grey. Adjustments that would allow chemical fertilizers when they are needed –for example when a pest is becoming resistant to organic methods-”should be considered with an open mind,” says Badgley. And she adds that “the main goal of farming is to feed people, rather than sticking to one particular production method.”
Even for Kapelos, a world sustained by organic farming may seem far in the future. However, he gets a glimpse of this world every time he helps his vegetables grow in a natural way, bringing this future closer to reality one small step at a time.
