Organic farming
Organic farming, also known as organic agriculture or ecological farming, or biological farming, is an agricultural system that emphasizes the use of naturally occurring, non-synthetic inputs, such as compost manure, green manure, and bone meal and places emphasis on techniques such as crop rotation, companion planting, and mixed cropping. Biological pest control methods, such as the fostering of insect predators, are also encouraged. Organic agriculture can be defined as "an integrated farming system that strives for sustainability, the enhancement of soil fertility and biological diversity while, with rare exceptions, prohibiting synthetic pesticides, antibiotics, synthetic fertilizers, genetically modified organisms, and growth hormones". It originated early in the 20th century in reaction to rapidly changing farming practices. In 2019, the global area dedicated to certified organic agriculture amounted to, with more than half of this area being in Australia.
Organic standards are designed to allow the use of naturally occurring substances while prohibiting or severely limiting synthetic substances. For instance, naturally occurring pesticides, such as garlic extract, bicarbonate of soda, or pyrethrin, are permitted, while synthetic fertilizers and pesticides, such as glyphosate, are prohibited. Synthetic substances that are allowed only in exceptional circumstances may include copper sulfate, elemental sulfur, and veterinary drugs. Genetically modified organisms, nanomaterials, human sewage sludge, plant growth regulators, hormones, and antibiotic use in livestock husbandry are prohibited. Broadly, organic agriculture is based on the principles of health, care for all living beings and the environment, ecology, and fairness. Organic methods champion sustainability, self-sufficiency, autonomy and independence, health, animal welfare, food security, and food safety. It is often seen as part of the solution to the impacts of climate change.
Organic agricultural methods are internationally regulated and legally enforced by transnational organizations such as the European Union and also by individual nations, based in large part on the standards set by the International Federation of Organic Agriculture Movements, an international umbrella organization for organic farming organizations established in 1972, with regional branches such as IFOAM Organics Europe and IFOAM Asia. Since 1990, the market for organic food and other products has grown rapidly, reaching $150 billion worldwide in 2022 – of which more than $64 billion was earned in North America and EUR 53 billion in Europe. This demand has driven a similar increase in organically managed farmland, which grew by 26.6 percent from 2021 to 2022. As of 2022, organic farming is practiced in 188 countries and approximately worldwide were farmed organically by 4.5 million farmers, representing approximately 2 percent of total world farmland.
Organic farming can be beneficial on biodiversity and environmental protection at local level; however, because organic farming can produce lower yields compared to intensive farming, leading to increased pressure to convert more non-agricultural land to agricultural use in order to produce similar yields, it can cause loss of biodiversity and negative climate effects.
History
was practiced for thousands of years without the use of artificial chemicals. Artificial fertilizers were first developed during the mid-19th century. These early fertilizers were cheap, powerful, and easy to transport in bulk. Similar advances occurred in chemical pesticides in the 1940s, leading to the decade being referred to as the "pesticide era". These new agricultural techniques, while beneficial in the short-term, had serious longer-term side-effects, such as soil compaction, erosion, and declines in overall soil fertility, along with health concerns about toxic chemicals entering the food supply. In the late 1800s and early 1900s, soil biology scientists began to seek ways to remedy these side effects while still maintaining higher production.In 1921 the founder and pioneer of the organic movement, Albert Howard, and his wife Gabrielle Howard accomplished botanists, founded an Institute of Plant Industry to improve traditional farming methods in India. Among other things, they brought improved implements and improved animal husbandry methods from their scientific training; then by incorporating aspects of Indian traditional methods, developed protocols for the rotation of crops, erosion prevention techniques, and the systematic use of composts and manures. Stimulated by these experiences of traditional farming, when Albert Howard returned to Britain in the early 1930s he began to promulgate a system of organic agriculture.
In 1924 Rudolf Steiner gave a series of eight lectures on agriculture with a focus on influences of the moon, planets, non-physical beings and elemental forces. They were held in response to a request by adherent farmers who noticed degraded soil conditions and a deterioration in the health and quality of crops and livestock resulting from the use of chemical fertilizers. The lectures were published in November 1924; the first English translation appeared in 1928 as The Agriculture Course.
In July 1939, Ehrenfried Pfeiffer, the author of the standard work on biodynamic agriculture, came to the UK at the invitation of Walter James, 4th Baron Northbourne as a presenter at the Betteshanger Summer School and Conference on Biodynamic Farming at Northbourne's farm in Kent. One of the chief purposes of the conference was to bring together the proponents of various approaches to organic agriculture in order that they might cooperate within a larger movement. Howard attended the conference, where he met Pfeiffer. In the following year, Northbourne published his manifesto of organic farming, Look to the Land, in which he coined the term "organic farming". The Betteshanger conference has been described as the 'missing link' between biodynamic agriculture and other forms of organic farming.
In 1940, Howard published his An Agricultural Testament. In this book he adopted Northbourne's terminology of "organic farming". Howard's work spread widely, and he became known as the "father of organic farming" for his work in applying scientific knowledge and principles to various traditional and natural methods. In the United States J. I. Rodale, who was keenly interested both in Howard's ideas and in biodynamics, founded in the 1940s both a working organic farm for trials and experimentation, The Rodale Institute, and Rodale, Inc., in Emmaus, Pennsylvania, to teach and advocate organic methods to the wider public. These became important influences on the spread of organic agriculture. Further work was done by Lady Eve Balfour in the United Kingdom, and many other places across the world.
The term "eco-agriculture" was coined in 1970 by Charles Walters, founder of Acres Magazine, to describe agriculture which does not use "man-made molecules of toxic rescue chemistry", effectively another name for organic agriculture.
Increasing environmental awareness in the general population in modern times has transformed the originally supply-driven organic movement to a demand-driven one. Premium prices and some government subsidies attracted farmers. In the developing world, many producers farm according to traditional methods that are comparable to organic farming, but not certified, and that may not include the latest scientific advancements in organic agriculture. In other cases, farmers in the developing world have converted to modern organic methods for economic reasons.
Terminology
The term "organic," as popularized by Howard and Rodale, specifically pertains to the utilization of Soil organic matter from plant compost and animal manures to enhance soil humus content, based on the research of early soil scientists who pioneered the concept of "humus farming." Since the early 1940s, the two factions have increasingly converged.Biodynamic agriculturists, on the other hand, used the term "organic" to indicate that a farm should be viewed as a living organism, in the sense of the following quotation:
They based their work on Steiner's spiritually-oriented alternative biodynamic agriculture which includes various esoteric concepts.
Methods
Organic farming methods combine scientific knowledge of ecology and some modern technology with traditional farming practices based on naturally occurring biological processes. Organic farming methods are studied in the field of agroecology. While conventional agriculture uses synthetic pesticides and water-soluble synthetically purified fertilizers, organic farmers are restricted by regulations to using natural pesticides and fertilizers. An example of a natural pesticide is pyrethrin, which is found naturally in the Chrysanthemum flower. The principal methods of organic farming include crop rotation, green manures and compost, biological pest control, and mechanical cultivation. These measures use the natural environment to enhance agricultural productivity: legumes are planted to fix nitrogen into the soil, natural insect predators are encouraged, crops are rotated to confuse pests and renew soil, and natural materials such as potassium bicarbonate and mulches are used to control disease and weeds. Genetically modified seeds and animals are excluded.While organic is fundamentally different from conventional because of the use of carbon-based fertilizers compared with highly soluble synthetic based fertilizers and biological pest control instead of synthetic pesticides, organic farming and large-scale conventional farming are not entirely mutually exclusive. Many of the methods developed for organic agriculture have been borrowed by more conventional agriculture. For example, Integrated Pest Management is a multifaceted strategy that uses various organic methods of pest control whenever possible, but in conventional farming could include synthetic pesticides only as a last resort. Examples of beneficial insects that are used in organic farming include ladybugs and lacewings, both of which feed on aphids. The use of IPM lowers the possibility of pest developing resistance to pesticides that are applied to crops.
