The global farmland area certified organic has expanded more than threefold to 37 million hectares since 1999, according to new research conducted by the Worldwatch Institute. The Institute argues that organic farming has the potential to contribute to sustainable food security by improving nutrition intake and sustaining rural livelihoods, while reducing vulnerability to climate change and enhancing biodiversity.
“Organic farming is now established in international standards, and 84 countries had implemented organic regulations by 2010,” wrote Catherine Ward and Laura Reynolds, Worldwatch researchers and lead authors of the report.
The International Federation of Organic Agriculture Movements defines organic agriculture has a production system that relies on ecological processes rather than the use of synthetic inputs (e.g. chemical fertilizers and pesticides). While organic farming has been practiced throughout most of human history, its modern roots lie in the middle of the last century. The period following World War II has come to be known as the “golden age of pesticides” because the use of agricultural chemicals was rife. But as the health and ecological ramifications of agrochemicals became clear, governments started to regulate their use and consumers started to demand organically certified foods.
“Although organic agriculture often produces lower yields on land that has recently been farmed conventionally, it can outperform conventional practices—especially in times of drought—when the land has been farmed organically for a longer time,” said Reynolds, a researcher with Worldwatch’s Food and Agriculture Program in a recent press release.
Conventional agricultural practices often degrade the environment through soil erosion, excessive water extraction, and biodiversity loss. This is of great concern when at least 1 billion people do not have adequate access to sufficient food. The report touts that organic farming can reduce vulnerability to climate change and enhance biodiversity, while increasing food security.
“While it has been presented as unrealistic for organic farming to feed the world, it seems that conventional farming does much more to threaten our food supply,” Reynolds told mongabay.com.” Growing all of our food using petroleum-dependent fertilizers and machinery, and spraying chemical pesticides and herbicides to reduce beneficial biodiversity and deplete soil nutrients, amounts to building our food supply on a fragile house of cards. If the price of oil rises, or populations of critical biodiversity that support food growth (bees, earthworms) collapse, we will be unequipped to produce food.”
Sustainable practices associated with organic farming are relatively labor intensive, and as such use up to 50 percent less fossil fuel energy than conventional farming. Common organic practices—including rotating crops, applying mulch to empty fields, and maintaining perennial shrubs and trees on farms—
also stabilize soils and improve water retention.
In addition, Reynolds notes that, “a few farm systems trials have found that organic agriculture actually out-produces conventional over the longer-term. The Rodale Institute has conducted comparative trials over the last forty years, and found multiple benefits to organic agriculture (soil health, farmer incomes, energy efficiency, reduction in greenhouse gas emissions) over conventional.”
Currently, organic agriculture certifications are mostly concentrated in wealthier countries. As an example, from 2009 to 2010, Europe increased its organic farmland by 9 percent to 10 million hectares. And while the United States has lagged behind other countries in adopting sustainable farming methods, the U.S. organic industry is one of the fastest-growing industries in the nation, expanding by 9.5 percent in 2011 to reach $31.5 billion in sales.
However, the report suggests that organic agriculture will become increasingly important in developing countries. In fact, 1.28 million global certified organic farmers already live in the developing world (approximately 80 percent). What’s more, non-certified organic agriculture in developing countries is practiced by millions of indigenous people, peasants, and small family farms involved in subsistence and local market-oriented production.
Organic farming in the developing world is now recognized as one possible way to address problems of food insecurity and climate change. Bhutan, for example, announced during the Delhi Sustainable Development Summit 2013 that it would ban the sale of pesticides and herbicides putting the country on track to be the first wholly organic nation in the world.
“Small plot farming in Zambia, Malawi, Niger, and Burkina Faso has drawn on organic methods to restore soils; this has resulted in higher food crop yields, greater household food security, and increased incomes,” write Ward and Reynolds in their recent report.
In the decades ahead the global food system will experience massive pressure to meet the demands of a growing population. Almost three-quarters of the world’s poor depend on agriculture for their income. Before broadening to sustainable agriculture it might be necessary to make sure that the constraints that presently encumber organic farming practices—problems like getting enough organic supplements, lack of access to certification, and limited local market access for organic produce—are tackled. As Ward and Reynolds conclude, “Increasing food production alone is not sufficient to combat hunger.”

The scientists theorize that stress may be why organic farming produces a more nutritious and tastier tomato.
(11/28/2012) With the worst effects of climate change, we are seeing how pollution hurts both human health and the environment but there is good news: a new study shows that organic farming stores more greenhouse gases in the soil than non-organic farming. By switching to organic methods, many farmers across the globe may be helping to solve the climate crisis at the same time as they improve soil quality and avoid the use of pesticides.
(09/27/2012) In the Uttar Kannada district of the Western Ghats, the livelihood of the average individual depends largely on the well being of the environment. Six months ago, before large-scale mangrove planting of the area, if someone were to walk through the banks of the mangroves in the Western Ghats he would see many fishermen casting their long nets and wires, time and time again noticing pieces of trash such as plastic grocery bags tangled in the nets.
(04/26/2012) In general, industrial agriculture beats organic farming in yields, according to a comprehensive new study in Nature. The study adds new data to the sometimes heated debate of organic versus conventional farming. Proponents of organic farming argue that these practices are environmentally friendly, sustainable over the long-term, and provide a number of social goods. However, critics argue that organic farming requires more land, thereby increasing global deforestation, which offsets any other environmental benefits of organic food production. At stake is whether organic or conventional is capable of feeding the world’s seven billion people (and rising), including increasing demand for energy-intensive foods like meat in the developing world.
(10/13/2011) At the end of this month the UN predicts global population will hit 7 billion people, having doubled from 3.5 billion in less than 50 years. Yet even as the Earth hits this new milestone, one billion people do not have enough food; meanwhile the rapid expansion of agriculture is one of the leading causes of global environmental degradation, including greenhouse gas emissions, destruction of forests, marine pollution, mass extinction, water scarcity, and soil degradation. So, how do we feed the human population—which continues to rise and is expected to hit nine billion by 2050—while preserving the multitude of ecosystem services that support global food production? A new study in Nature proposes a five-point plan to this dilemma.
(09/01/2011) Organic farming is more profitable and economically secure than conventional farming even over the long-term, according to a new study in Agronomy Journal. Using experimental farm plots, researchers with the University of Minnesota found that organic beat conventional even if organic price premiums (i.e. customers willing to pay more for organic) were to drop as much as 50 percent.
(09/01/2011) Given that we have very likely entered an age of mass extinction—and human population continues to rise (not unrelated)—researchers are scrambling to determine the best methods to save the world’s suffering species. In the midst of this debate, a new study in Science, which is bound to have detractors, has found that setting aside land for strict protection coupled with intensive farming is the best way to both preserve species and feed a growing human world. However, other researchers say the study is missing the point, both on global hunger and biodiversity.
