Organic farming is a form of agriculture which avoids or largely excludes the use of synthetic
fertilizers and
pesticides, plant growth regulators, and livestock feed additives. As far as possible organic farmers rely on
crop rotation, crop residues, animal manures and mechanical cultivation to maintain soil productivity and tilth, to supply plant nutrients, and to control weeds, insects and other pests.
According to the international organic farming organisation IFOAM :
The role of organic agriculture, whether in farming, processing, distribution, or consumption, is to sustain and enhance the health of ecosystems and organisms from the smallest in the soil to human beings.
Organic farming is also associated with support for principles beyond cultural practices, such as
fair trade and environmental stewardship, although this does not apply to all organic farms and farmers.
Overview
Organic farming excludes the use of synthetic inputs, such as synthetic
fertilizers and
pesticides, and
genetically modified organisms . However organic farming regulations, as defined by the U.S.D.A, do not prohibit GMOs ]. In many countries the use of
veterinary drugs is excluded . In a number of countries, including the US, Bulgaria, Iceland, Norway, Romania, Switzerland, Turkey, Australia, India, Japan, the Philippines, Korea, Taiwan, Thailand, Argentina, Costa Rica, Tunisia, and in the EU, organic farming is also defined by law, so that the commercial use of the term
organic to describe farming and food products is regulated by the government. Where laws exist,
organic certification is available to farms for a fee, and it is usually illegal for a non-certified farm to call itself or its products
organic. Elsewhere, for example, in
Canada, voluntary certification is available, while legislation may be pending.
Methods of organic farming vary. However, organic approaches share common goals and practices. In addition to the exclusion of synthetic agrichemicals, these include protection of the soil , promotion of
biodiversity , and outdoor grazing for livestock and poultry. Within this framework, individual farmers develop their own organic production systems, determined by factors such as climate, market conditions, and local agricultural regulations.
History
The organic movement began as a reaction of insiders against the industrialization of agriculture.
Advances in biochemistry, and engineering in the early 20th century led to profound changes in farming. Research in
plant breeding produced hybrid seeds. Fields grew in size and cropping became specialized to make efficient use of machinery and reap the benefits of the
green revolution.
Technological advances during
World War II spurred on post-war innovation in all aspects of agriculture, resulting in such advances as large-scale irrigation, fertilization, and the use of
pesticides.
Ammonium nitrate, used in munitions, became an abundantly cheap source of nitrogen.
DDT, originally developed by the military to control disease-carrying insects among troops, was applied to crops, launching the era of widespread
pesticide use.
While some indigenous cultures had been farming organically for centuries, organic agriculture began to develop consciously in Central Europe and India in the early twentieth century as a reaction to industrialization. The British botanist, Sir Albert Howard often called “the father of modern organic agriculture” studied traditional farming practices in
Bengal,
India. He came to regard such practices as superior to modern agricultural science and recorded them in his 1940 book,
An Agricultural Testament.
In Germany,
Rudolf Steiner's
Spiritual Foundations for the Renewal of Agriculture, published in 1924, led to the popularization of biodynamic agriculture.
The first use of the term
organic farming is usually credited to Lord Northbourne, in his book,
Look to the Land , wherein he described a holistic, ecologically balanced approach to farming.
In the US, J.I. Rodale popularized
organic gardening among consumers.
In 1972, the International Federation of Organic Agriculture Movements , was founded in
Versailles, France. IFOAM was dedicated to the diffusion of information on the principles and practices of organic agriculture across national and linguistic boundaries.
In the 1980s, various farming and consumer groups worldwide began pressing for government regulation of organic production. This led to legislation and certification standards being enacted beginning in the 1990s.
Since the early 1990s, the retail market for organic farming in developed economies has grown about 20 per cent annually due to increasing consumer demand. While small independent producers and consumers initially drove the rise of organic farming, meanwhile as the volume and variety of "organic" products grows, production is increasingly large-scale.
Methods
Organic farming involves fostering natural processes, often over extended periods of time, and what advocates describe as a holistic approach.
Enhancing soil health is the cornerstone of organic farming. This is a biological process, driven by
microorganisms, that allows the natural production of nutrients in the soil throughout the growing season, and has been referred to as
feeding the soil to feed the plant. A variety of methods are employed, including crop rotation, green manure, cover cropping, application of
compost, and mulching. Organic farmers also use processed natural fertilizers such as seed meal, and various mineral powders such as rock phosphate and greensand, a naturally occurring form of potash.
Differing approaches to pest control are equally notable. In conventional farming, a specific insecticide may be used against a particular insect pest. Chemical controls can dramatically reduce pest populations for the short term, yet by unavoidably killing natural predator insects and animals, can cause an ultimate increase in the pest population. Repeated use of insecticides and
herbicides and other
pesticides can encourage
natural selection of resistant insects, plants and other organisms.
Pest control targets animal pests , weeds and disease. Organic pest control involves the cumulative effect of many techniques, including, allowing for an acceptable level of pest damage, encouraging or even introducing beneficial organisms, careful crop selection and crop rotation, and mechanical controls such as row covers and traps. These techniques generally provide benefits in addition to pest control—soil protection and improvement, fertilization, pollination, water conservation, season extension, etc.—and these benefits are both complementary and cumulative in overall effect on farm health. Effective organic pest control requires a thorough understanding of pest life cycles and interactions.
Weeds are controlled mechanically, thermically and through the use of mulches.
Organic farms that raise livestock and poultry, for meat, dairy and eggs, provide animals with "natural" living conditions and feed. Ample, free-range outdoor access, for grazing and exercise, is a distinctive feature, and crowding is avoided. Feed is also organically grown, and the addition of drugs, including antibiotics, are prohibited by organic standards. Animal health and food quality are thus pursued in a holistic "fresh air, exercise, and good food" approach.
Organic farming systems
There are a number of formal organic farming systems that prescribe specific techniques. They tend to be more specific than, and fit within, general organic standards. Biodynamic farming is an approach, based on the esoteric teachings of
Rudolf Steiner. The Japanese farmer and writer
Masanobu Fukuoka invented a no-till system for small-scale grain production that he called Natural Farming. French intensive and biointensive methods are both small scale gardening techniques.
Standards
Increasingly, organic farming is defined by formal standards regulating production methods, and in some cases, final output. Two types of standard exist, voluntary and legislated. As early as the 1970s, private associations created standards, against which organic producers could voluntarily have themselves certified. In the 1980s, governments began to produce organic production guidelines. Beginning in the 1990s, a trend toward legislation of standards began, most notably the EU-Eco-regulation developed in the
European Union.
In 1991, the European Commission formulated the first government system to regulate organic labelling. In one go, the European Regulation 2092/91 set the rules in 12 countries, creating a huge market. Organic certification, which till then was a voluntary quality control system, became mandatory to all operations and was also to be applied for imports. In the meantime, Europe had become the most prominent market place for organic products and an increasing number of suppliers all over the world accepted this niche as a new challenge and a rewarding option to export high quality and high priced speciality products. All these supplies, of course, had to comply with the requirements of the European market and thus the Regulation N° 2092/91 became a universal standard for organic production systems
An international framework for organic farming is provided by the International Federation of Organic Agriculture Movements , the international democratic umbrella organization established in 1972. For IFOAM members, organic agriculture is based upon the Principles of Organic Agriculture and the IFOAM Norms. The IFOAM Norms consist of the IFOAM Basic Standards and IFOAM Accreditation Criteria.
The IFOAM Basic Standards are a set of "standards for standards." They are established through a democratic and international process and reflect the current state of the art for organic production and processing. They are best seen as a work in progress to lead the continued development of organic practices worldwide. They provide a framework for national and regional standard-setting and certification bodies to develop detailed certification standards that are responsive to local conditions.
Legislated standards are established at the national level, and vary from country to country. In recent years, many countries have legislated organic production, including the EU nations , Japan , and the US . Non-governmental national and international associations also have their own production standards. In countries where production is regulated, these agencies must be accredited by the government.
Since 1993 when
EU Council Regulation 2092/91 became effective, organic food production has been strictly regulated in the
UK.
.
In India, standards for organic agriculture were announced in May 2001, and the National Programme on Organic Production is administered under the Ministry of Commerce.
In 2002, the
United States Department of Agriculture established production standards, under the
National Organic Program , which regulate the commercial use of the term
organic. Farmers and food processors must comply with the NOP in order to use the word.
Productivity
A 22-year farm trial study by Cornell University published in 2005 concluded that organic farming produces the same corn and soybean yields as conventional methods, but consumes less energy and contains no pesticide residues. However, a prominent 21-year Swiss study found an average of 20% lower organic yields over conventional, along with 50% lower expenditure on fertilizer and energy, and 97% less pesticides. A major US survey published in 2001, analyzed results from 150 growing seasons for various crops and concluded that organic yields were 95-100% of conventional yields. Comparative yield studies are still scarce, and overall results remain "inconclusive".
The issue of productivity is more complex than a summary of yield , which was the measure used in these studies. Instead, productivity could be calculated in labour time rather than by land area. Organic methods often require more labor, providing rural jobs but increasing costs to urban consumers. Also, grain forms the majority of world agricultural production, and most of that is fed to animals, not humans—broad calculations of how much agriculture is feeding people is therefore complicated when feeding animals to feed people is factored in.
Issues
All aspects of organic farming and organic food are under debate. Environmentalists, food safety advocates, various consumer protection, social justice and labor groups, small independent farmers, and a growing number of food consumers are ranged against agribusiness and current government agricultural policies.
The controversy centers on the overall value and safety of chemical agriculture, with organic farming popularly regarded as the "opposite" of modern, large-scale, chemical-based farming. As public awareness increases, there are a number of obstacles to an easy grasp of the overall situation.
The following topics may be argued from both sides.
Pesticides
Organic farming standards do not allow the use of synthetic
pesticides, but it does allow the use of certain so-called natural pesticides, such as those derived from plants. Organic advocates state that natural pesticides are a last resort, growing healthier, disease-resistant plants, using cover crops and crop rotation, and encouraging beneficial insects and birds as the primary methods of pest control. The most common organic pesticides, accepted for restricted use by most organic standards, include Bt, pyrethrum, and
rotenone.
Critics argue that organic farms can work without using pesticides because pests are kept under control in surrounding conventional farms and thus do not spread into organic farms, if it became universal, the "islands" they operate on would disappear and pests would become a severe issue. This argument also works in reverse, as organic farms can be islands of safety for
predator insects and
pollinators, without which, more
pollination services would be required, and ever-increasing quantities of pesticides would be needed as pest populations acquired resistance to pesticides .
Workplace safety is a separate, related issue. Pesticides create a hazardous work environment. Chemical accidents and the effects of long-term exposure are both well-known risks faced by many farm workers. Also, the effect of chemicals, airborne after spraying, and in the groundwater, on neighboring communities is a concern.
Genetically modified organisms
A key characteristic of organic farming is its rejection of genetically engineered products, including plants and animals. On October 19, 1998, participants at IFOAM's 12th Scientific Conference of IFOAM) issued the Mar del Plata Declaration, where more than 600 delegates from over 60 countries voted unanimously to exclude the use of genetically modified organisms in food production and agriculture. From this point, it became widely recognized that GMOs are categorically excluded from organic farming.
"GMO-free" is also a popular marketing point for organic food. The general argument against is that no one has a clue as to the full impact of
genetic engineering on food quality, plant or animal health: GE is preparing our food supply for collapse. On the other side, the argument is that with a rapidly expanding global population, genetic engineering to create higher volumes of produce could be the key to ending world hunger. It also could be the key to creating healthier food, and ensuring proper nourishment, and has the potential to make farming more profitable, allowing agricultural industries to survive in increasingly service oriented economies. Often overlooked in this debate is the fact that genetic engineering is a technique, not an essential characteristic of the organisms it produces, and that humans have used selective breeding to modify crops and livestock for tens of thousands of years.
A recent advancement in GE involving the insertion of a gene from an animal into the cell or seed of a plant is proving to be highly controversial. The science is still in the early stages of development and its future implications on sustainable agriculture and organic farming may add considerable support to the argument against genetic engineering.
The contamination of organic farms with GM product, usually through pollination, is an important issue. Contamination may lead to products being incorrectly labelled as organic or GMO-free, or may reduce the value of crop as it cannot be sold as organic, leading to losses for the farmer.
The mechanism of cross-contamination is not understood, and only beginning to be studied. Meanwhile, cases of cross-contamination have been documented, while the extent is still unclear. A first-time study of genetic cross-contamination, published in Feb. 2004, found that at least two-thirds of conventional corn, soybeans and canola in the US contain traces of genetic material from GM varieties. Along with commercial GM crops, trials for new GM plants producing food,
pharmaceuticals and industrial materials , are being conducted in the US, Canada, and elsewhere. With the genetic engineering of
alfalfa , a primary green manure fertilizer crop, not only primary crops, but the underpinnings of organic agriculture are threatened. It is conceivable that genetic contamination could make GMO-free farming next to impossible.
The environment
The environmental argument, from the pro-organic view, holds that conventional agriculture is rapidly depleting natural resources, particularly
fossil fuels and fresh water, and seriously
polluting soil, water and air. Cited are the large quantities of agricultural chemicals in use , water wastage through high-volume irrigation, heavy use of petrochemicals for farm machinery and long-distance transport, high densities of various waste products from concentrated operations, and the list goes on. While there is no argument that conventional agriculture relies on an abundance of these resources and creates a high volume of waste, agribusiness supporters argue that the negative claims are exaggerated or inaccurate. The fact that the current food industry exists and has fed the much of the world for several decades is the biggest pro-argument to date.
On the flip side, large-scale organic operations that don't follow sustainable practices would require many of the same resources as conventional operations. For example, an organic farm that made heavy use of farm machinery and indoor production facilities , and shipped to far-off markets, would still be a major consumer of energy resources. Also, it is debated whether an organic farm using natural compost and manure on a large scale would cause any less damage to ground water and soil than manufactured fertilizers.
Interestingly, many organic farms rely on manure that is not organic to continue fertilization. This technically does not violate the traditional definitions of organic produce because there are no inorganic components added to the manure, although they may be present in its composition. Studies of the effects of chemicals within manure on organic produce is limited, although studies have shown that many carcinogens are present in variable amounts in even organic foodstuffs.
Some critics, most notably
Norman Borlaug, contend that adopting organic farming methods on a global scale would be more detrimental to the environment than conventional farming. Borlaug asserts that if organic farming is to feed the globe, it will require a dramatic increase in cropland area, and that achieving this goal will ultimately lead to wide-scale
deforestation.
Food contamination
Critics point out organic food could be less safe than non-organic food, by increasing the risk of exposure to biological contaminants and food-borne diseases. In particular concerns are related to the use of manure, well known for carrying human pathogens and presence of mycotoxins from molds. One large, influential French study, evaluating organic and conventional food during 1999-2000, warned that biological toxins in certain organic products should be closely monitored. Food contamination is usually caused by unhygienic handling and storage, including use of contaminated water, which can occur on-farm, in transit, and at the point of preparation. On the other hand, there has been no concrete evidence as of yet showing a direct link between organic farming practices and food contamination.
Food quality
Although
organic food is a topic in its own right, there are concerns related specifically to the quality of raw, fresh food. Without conclusive science either way, some organic supporters believe that the overall nutritional and health-promoting value of food is compromised by chemical-farming methods. This involves areas like micronutrients and trace elements, plant physiology, the way plants grow and the process of human nutrition. The common sense appeal is that food grown in unnatural, sheltered, chemically assisted ways isn't as "good" for people as "naturally grown" food, as some things are different or missing. The counter-argument is that, by currently accepted standards of food science, there has been no demonstration of a functional difference between organically and conventionally produced food, and that assisted food is actually healthier and thus, more nutritious. Further, there is some concern that due to the limited methods available to organic farmers for combating quality problems while adhering to organic standards, some organic food does not generally achieve comparable safety and quality standards as "conventionally" grown products.
Children's Health
A 2001 demonstrated that children fed organic diets experienced significantly lower organophosphorus pesticide exposure than children fed conventional diets. Additionally, in 2005 the EPA's "Guidelines for Carcinogen Risk Assessment" showed that children receive 50% of their lifetime risks of cancer during their first two years of life . These studies and others like it have helped spur a growing organic baby food trend in the United States. Mothers are more and more hesitant to feed their children potentially dangerous food, given that their small bodies are especially vulnerable to toxins.
Soil conservation
The practice of
ploughing to prepare soil for planting is claimed to increase soil damage compared to using herbicides, like
glyphosates. In fact, this argument applies primarily to large-scale, chemical-based agriculture, where huge areas are repeatedly tilled and planted with the same crops. By using artificial fertilizer rather than replacing organic material, the soil structure is progressively destroyed, and becomes increasingly susceptible to wind and water erosion. Use of herbicides to kill weeds, instead of plowing them under, may present a short-term solution to this problem. However, repeated use of herbicides also kills microorganisms that contribute to the decomposition of plant residues that help rebuild the organic matter that holds the soil together. It also encourages the selection of the most herbicide-resistant weeds, which necessitates increased herbicide use.
Rural infrastructure
Critics condemn agribusiness practices for putting small, independent farmers out of business, destroying rural communities in the process, and causing the "art of farming" to be lost. According to these critics, small-scale organic farming encourages local economies, and provides social and employment alternatives to concentrated, energy-dependent urban living, thus improving the quality of life for everyone.
As discussed previously, the entry of large-scale businesses into production of organic food undermines the belief that a preference by consumers for organic food will necessarily translate into a substantive change in the nature of agribusiness. This is where the distinction between organic farming, organic food, and organic certification becomes tricky. If the strong consumer trend represents simply the desire for an "organic" stamp on their food, then the trend to large-scale, global, corporate farming, certified organic or not, will continue. If consumers embrace a broader concept of "organic", which includes fresh, local food, substantial changes in the food industry would have to follow to meet this demand.
Sustainability
Although it is common to equate organic farming with sustainable agriculture, the two are not synonymous. Sustainability in agriculture is a broad concept, with considerations on many levels, such as "environmental health, economic profitability, and social and economic equity." With regard to organic farming methods, one goal of sustainability would be to approach as closely as possible a balance between what is taken out of the soil with what is returned to it, without relying on outside inputs. An organic operation that imports the manure it uses to replace the nutrients taken out of the soil by crops, must factor in the resources required to produce and transport that manure, when calculating sustainability. Organic farming today is a small part of the agricultural landscape, with a relatively minor impact on the environment. As the size of organic farms continues to increase, a new set of large-scale considerations will eventually have to be tackled. Large organic
farms that rely on machinery and automation, and purchased inputs, will have similar sustainability issues as large conventional farms do today.
Certification
Organic certification, particularly where mandated by law, as in the US and the EU, is increasingly being seen by individual organic farmers and consumers as a contentious issue. Where the push for regulation was originally a grassroots effort by organic producers and buyers looking to uphold standards and prevent fraud, the complex regulations and opportunities for loopholes that have emerged have led to charges being levelled against major certifiers and government programs. In the US, where standards became law in 2002, serious complaints have been lodged with the USDA against the largest US certifying agency, and the USDA itself has been taken to court, based on such challenges. A leading US proponent of organic farming, Eliot Coleman, who served as an adviser to the USDA during the drafting of the original organic guidelines in the US in the 1980s, and served a term as Director of IFOAM, more recently stated: "The label 'organic' has lost the fluidity it used to hold for the growers more concerned
with quality than the bottom line, and consumers more concerned with nutrition than a static set of standards for labeling." Concern about the "watering down" of standards to facilitate large-scale production is currently a significant aspect of organic farming regulation.
The future
Organic farming is at a crossroads. Despite the growth in the organic food market over the last decade, the future of the small, independent farmer, organic or otherwise, is as much in jeopardy now as it has been in recent decades. The local infrastructure to support small farmers is all but non-existent in most developed nations - the current food distribution system favors high-volume production, and large farming operations. What is commonly known as "organic farming" may change quite dramatically in the coming few years.
Organic farming is now gaining popularity and is being accepted by people all over the world. In Deborah Koons Garcia's film
The Future of Food, it is stated that the American market for organically grown food amounted to $1 billion in 1994, and $13 billion in 2003. A growing consumer market is naturally one of the main factors encouraging farmers to convert to organic agricultural production. Increased consumer awareness of food safety issues and environmental concerns has contributed to the growth in organic farming over the last few years.
