Organic farming, also known as ecological farming or biological farming,[1][2][3][4][5] is an agricultural system that uses fertilizers of organic origin such as compost manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and companion planting. It originated early in the 20th century in reaction to rapidly changing farming practices. Certified organic agriculture accounts for 70 million hectares (170 million acres) globally, with over half of that total in Australia.[6] Biological pest control, mixed cropping, and the fostering of insect predators are encouraged. Organic standards are designed to allow the use of naturally-occurring substances while prohibiting or strictly limiting synthetic substances.[7] For instance, naturally-occurring pesticides such as pyrethrin are permitted, while synthetic fertilizers and pesticides are generally prohibited. Synthetic substances that are allowed include, for example, 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.[8][9] Organic farming advocates claim advantages in sustainability,[10][11] openness, self-sufficiency, autonomy and independence,[11] health, food security, and food safety.
Organic agricultural methods are internationally regulated and legally enforced by transnational organizations (as European Union) and many nations, based in large part on the standards set by the International Federation of Organic Agriculture Movements (IFOAM), an international umbrella organization for organic farming organizations established in 1972.[12] 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".[13][14][15][16]
Since 1990, the market for organic food and other products has grown rapidly, reaching $63 billion worldwide in 2012.[17]: 25 This demand has driven a similar increase in organically managed farmland that grew from 2001 to 2011 at a compounding rate of 8.9% per year.[18] As of 2022, approximately 96,000,000 hectares (240,000,000 acres) worldwide were farmed organically, representing approximately 2% of total world farmland.[19]
Organic farming can be beneficial on biodiversity and environmental protection at local level; however, because organic farming has sometimes lower yields compared to intensive farming, additional agricultural land is needed elsewhere in the world, which means that natural and forest land has to be converted into agricultural land. This can cause loss of biodiversity and negative climate effects that sometimes outweigh the local environmental gains achieved. This lower yields does not include dry lands.[20]
Various types and methods of organic agriculture have been developed in the Northern Hemisphere, such as the biological-organic and biodynamic method
the term biological often refers to organic farming, whereas the term ecological refers to organic plus environmental considerations such as on-farm wildlife management
A form of production (also organic farming, ecological farming, ecological-biological farming, ecological agriculture, alternative agriculture) for the production of food and other agricultural products
Biological farming and 'bio' products are terms often used in European countries as equivalent to organic farming. [...] Ecological farming and 'eco' products are terms also used in European countries as equivalent to organic farming.
