You can help Misplaced Pages by expanding it . Farming Agriculture encompasses crop and livestock production, aquaculture , and forestry for food and non-food products. Agriculture

224-787: A lord of the manor with a Roman Catholic church and priest. Thanks to the exchange with the Al-Andalus where the Arab Agricultural Revolution was underway, European agriculture transformed, with improved techniques and the diffusion of crop plants, including the introduction of sugar, rice, cotton and fruit trees (such as the orange). After 1492, the Columbian exchange brought New World crops such as maize, potatoes, tomatoes, sweet potatoes , and manioc to Europe, and Old World crops such as wheat, barley, rice, and turnips , and livestock (including horses, cattle, sheep and goats) to

336-706: A GM content above 1.0%. In Canada and the United States labeling of GM food is voluntary, while in Europe all food (including processed food ) or feed which contains greater than 0.9% of approved GMOs must be labelled. In the US state of Oregon., voters rejected Measure 27, which would have required labeling of all genetically modified foods. Japan, Malaysia, New Zealand, and Australia require labeling so consumers can exercise choice between foods that have genetically modified, conventional or organic origins. The Cartagena Protocol sets

448-472: A Physical Containment level 1 (PC1) or Physical Containment level 2 (PC2) laboratories. Laboratory work with GMOs classified as low risk, which include knockout mice , are carried out in PC1 lab. This is the case for modifications that do not confer an advantage to the animal or doesn't secrete any infectious agents. If a laboratory strain that is used isn't covered by exempt dealings or the inserted DNA could code for

560-417: A combination of labor supply and labor demand trends have driven down the share of population employed in agriculture. During the 16th century in Europe, between 55 and 75% of the population was engaged in agriculture; by the 19th century, this had dropped to between 35 and 65%. In the same countries today, the figure is less than 10%. At the start of the 21st century, some one billion people, or over 1/3 of

672-400: A comparative method for assessing safety needs to be adopted. For instance, potatoes and tomatoes can contain toxic levels of respectively, solanine and alpha-tomatine alkaloids. To decide if a modified product is substantially equivalent, the product is tested by the manufacturer for unexpected changes in a limited set of components such as toxins, nutrients, or allergens that are present in

784-483: A fertilizer for crops. Regulation of genetic engineering The regulation of genetic engineering varies widely by country. Countries such as the United States, Canada, Lebanon and Egypt use substantial equivalence as the starting point when assessing safety, while many countries such as those in the European Union, Brazil and China authorize GMO cultivation on a case-by-case basis. Many countries allow

896-664: A hazardous industry, and farmers worldwide remain at high risk of work-related injuries, lung disease, noise-induced hearing loss , skin diseases, as well as certain cancers related to chemical use and prolonged sun exposure. On industrialized farms , injuries frequently involve the use of agricultural machinery , and a common cause of fatal agricultural injuries in developed countries is tractor rollovers . Pesticides and other chemicals used in farming can be hazardous to worker health , and workers exposed to pesticides may experience illness or have children with birth defects. As an industry in which families commonly share in work and live on

1008-444: A high use of inputs (water, fertilizer, pesticide and automation). It is practiced mainly in developed countries. From the twentieth century onwards, intensive agriculture increased crop productivity. It substituted synthetic fertilizers and pesticides for labor, but caused increased water pollution, and often involved farm subsidies. Soil degradation and diseases such as stem rust are major concerns globally; approximately 40% of

1120-445: A low risk. These include systems using standard laboratory strains as the hosts, recombinant DNA that does not code for a vertebrate toxin or is not derived from a micro-organism that can cause disease in humans. Exempt dealings usually do not require approval from the national regulator. GMOs that pose a low risk if certain management practices are complied with are classified as notifiable low risk dealings. The final classification

1232-641: A national regulatory group or legislation. All staff must be trained in the use of GMOs and in some laboratories a biological control safety officer is appointed. All laboratories must gain approval from their regulatory agency to work with GMOs and all experiments must be documented. As of 2008 there have been no major accidents with GMOs in the lab. The legislation covering GMOS was initially covered by adapting existing regulations in place for chemicals or other purposes, with many countries later developing specific policies aimed at genetic engineering. These are often derived from regulations and guidelines in place for

"An Illusory Consensus behind GMO Health Assessment" (PDF) . Science, Technology, & Human Values . 40 (6): 883–914. doi : 10.1177/0162243915598381 . Archived from the original (PDF) on 2019-08-31. I began this article with the testimonials from respected scientists that there

1456-513: A number of articles some of which have strongly and negatively influenced the public opinion on GM crops and even provoked political actions, such as GMO embargo, share common flaws in the statistical evaluation of the data. Having accounted for these flaws, we conclude that the data presented in these articles does not provide any substantial evidence of GMO harm. The presented articles suggesting possible harm of GMOs received high public attention. However, despite their claims, they actually weaken

1568-407: A pathogenic gene, it must be carried out in a PC2 laboratory. The approaches taken by governments to assess and manage the risks associated with the use of genetic engineering technology and the development and release of GMOs vary from country to country, with some of the most marked differences occurring between the United States and Europe. The United States takes on a less hands-on approach to

1680-447: A positive note, the gender gap in access to mobile internet in low- and middle-income countries fell from 25 percent to 16 percent between 2017 and 2021, and the gender gap in access to bank accounts narrowed from 9 to 6 percentage points. Women are as likely as men to adopt new technologies when the necessary enabling factors are put in place and they have equal access to complementary resources. Agriculture, specifically farming, remains

1792-423: A regulatory framework concerning genetic engineering began in 1975, at Asilomar , California. The first use of Recombinant DNA (rDNA) technology had just been successfully accomplished by Stanley Cohen and Herbert Boyer two years previously and the scientific community recognized that as well as benefits this technology could also pose some risks. The Asilomar meeting recommended a set of guidelines regarding

1904-404: A significant decrease in genetic diversity and resources among livestock breeds, leading to a corresponding decrease in disease resistance and local adaptations previously found among traditional breeds. Grassland based livestock production relies upon plant material such as shrubland , rangeland , and pastures for feeding ruminant animals. Outside nutrient inputs may be used, however manure

2016-485: A small area of forest is cleared by cutting and burning the trees. The cleared land is used for growing crops for a few years until the soil becomes too infertile, and the area is abandoned. Another patch of land is selected and the process is repeated. This type of farming is practiced mainly in areas with abundant rainfall where the forest regenerates quickly. This practice is used in Northeast India, Southeast Asia, and

2128-406: A standard safety test: There has been discussion about applying new biochemical concepts and methods in evaluating substantial equivalence, such as metabolic profiling and protein profiling. These concepts refer, respectively, to the complete measured biochemical spectrum (total fingerprint) of compounds (metabolites) or of proteins present in a food or crop. The goal would be to compare overall

2240-459: A variety of ways—biology, life cycles, or potential environmental impacts. GM plants and animals were being developed around the same time, but due to the complexity of their biology and inefficiency with laboratory equipment use, their appearance in the market was delayed. There are six categories that genetically engineered (GE) animals are approved for: But see also: Domingo, José L.; Bordonaba, Jordi Giné (2011). "A literature review on

2352-552: A year, or requiring irrigation. In all of these environments perennial crops are grown (coffee, chocolate) and systems are practiced such as agroforestry . In temperate environments, where ecosystems were predominantly grassland or prairie , highly productive annual farming is the dominant agricultural system. Important categories of food crops include cereals, legumes, forage, fruits and vegetables. Natural fibers include cotton, wool , hemp , silk and flax . Specific crops are cultivated in distinct growing regions throughout

The indigenous people of the Southwest and the Pacific Northwest practiced forest gardening and fire-stick farming . The natives controlled fire on a regional scale to create a low-intensity fire ecology that sustained a low-density agriculture in loose rotation; a sort of "wild" permaculture . A system of companion planting called

2688-536: Is a near universal system for assessing the relative risks associated with GMOs and other agents to laboratory staff and the community. They are then assigned to one of four risk categories based on their virulence, the severity of disease, the mode of transmission, and the availability of preventive measures or treatments. There are some differences in how these categories are defined, such as the World Health Organisation (WHO) including dangers to animals and

2800-514: Is associated with diseases that are not serious, risk group 3 is associated with serious diseases where treatments are available and risk group 4 is for serious diseases with no known treatments. In 1992 the Occupational Safety and Health Administration determined that its current legislation already adequately covers the safety of laboratory workers using GMOs. Australia has an exempt dealing for genetically modified organisms that only pose

2912-626: Is both a cause of and sensitive to environmental degradation , such as biodiversity loss , desertification , soil degradation , and climate change , all of which can cause decreases in crop yield. Genetically modified organisms are widely used, although some countries ban them . The word agriculture is a late Middle English adaptation of Latin agricultūra , from ager 'field' and cultūra ' cultivation ' or 'growing'. While agriculture usually refers to human activities, certain species of ant , termite and beetle have been cultivating crops for up to 60 million years. Agriculture

3024-444: Is defined with varying scopes, in its broadest sense using natural resources to "produce commodities which maintain life, including food, fiber, forest products, horticultural crops, and their related services". Thus defined, it includes arable farming , horticulture, animal husbandry and forestry , but horticulture and forestry are in practice often excluded. It may also be broadly decomposed into plant agriculture , which concerns

3136-859: Is focused on movement of GMOs between countries and has been called a de facto trade agreement. One hundred and seventy-two countries are members of the Protocol and many use it as a reference point for their own regulations. Also in 2003 the Codex Alimentarius Commission of the FAO/WHO adopted a set of "Principles and Guidelines on foods derived from biotechnology" to help countries coordinate and standardize regulation of GM food to help ensure public safety and facilitate international trade. and updated its guidelines for import and export of food in 2004, The European Union first introduced laws requiring GMOs to be labelled in 1997. In 2013, Connecticut became

3248-406: Is for any uses of GMOs that do not meet the previous criteria. These are known as licensed dealings and include cloning any genes that code for vertebrate toxins or using hosts that are capable of causing disease in humans. Licensed dealings require the approval of the national regulator. Work with exempt GMOs do not need to be carried out in certified laboratories. All others must be contained in

3360-478: Is governed by the Coordinated Framework for Regulation of Biotechnology The policy has three tenets: "(1) U.S. policy would focus on the product of genetic modification (GM) techniques, not the process itself, (2) only regulation grounded in verifiable scientific risks would be tolerated, and (3) GM products are on a continuum with existing products and, therefore, existing statutes are sufficient to review

3472-540: Is literally no scientific controversy over the health effects of GMOs. My investigation into the scientific literature tells another story. And contrast: Panchin, Alexander Y.; Tuzhikov, Alexander I. (January 14, 2016). "Published GMO studies find no evidence of harm when corrected for multiple comparisons".

Brazil and Argentina are the 2nd and 3rd largest producers of GM food. In Argentine assessment of GM products for release is provided by the National Agricultural Biotechnology Advisory Committee (environmental impact), the National Service of Health and Agrifood Quality (food safety) and

3808-420: Is voluntary, while in Europe all food (including processed food ) or feed which contains greater than 0.9% of approved GMOs must be labelled. There is a scientific consensus that currently available food derived from GM crops poses no greater risk to human health than conventional food, but that each GM food needs to be tested on a case-by-case basis before introduction. Nonetheless, members of

3920-454: Is whether GM products should be labeled. Labeling of GMO products in the marketplace is required in 64 countries. Labeling can be mandatory up to a threshold GM content level (which varies between countries) or voluntary. A study investigating voluntary labeling in South Africa found that 31% of products labeled as GMO-free had a GM content above 1.0%. In Canada and the US labeling of GM food

4032-597: The Control of Substances Hazardous to Health Regulations 2002 . Environmental risks are covered by Section 108(1) of the Environmental Protection Act 1990 and The Genetically Modified Organisms (Risk assessment) (Records and Exemptions) Regulations 1996. In the US the National Institute of Health (NIH) classifies GMOs into four risk groups. Risk group one is not associated with any diseases, risk group 2

4144-599: The Biological Agents and Toxins Act . For further review see Trump 2017. In Saudi Arabia's Neom project genetically engineered agriculture is legal, encouraged, and is funded by the government as an integral part of the project. One of the key issues concerning regulators is whether GM products should be labeled. Labeling can be mandatory up to a threshold GM content level (which varies between countries) or voluntary. A study investigating voluntary labeling in South Africa found that 31% of products labeled as GMO-free had

4256-494: The Indus Valley civilization . In China, from the 5th century BC, there was a nationwide granary system and widespread silk farming . Water-powered grain mills were in use by the 1st century BC, followed by irrigation. By the late 2nd century, heavy ploughs had been developed with iron ploughshares and mouldboards . These spread westwards across Eurasia. Asian rice was domesticated 8,200–13,500 years ago – depending on

In Greece and Rome , the major cereals were wheat, emmer, and barley, alongside vegetables including peas, beans, and olives. Sheep and goats were kept mainly for dairy products. In the Americas, crops domesticated in Mesoamerica (apart from teosinte) include squash, beans, and cacao . Cocoa

4928-536: The organic movement . Unsustainable farming practices in North America led to the Dust Bowl of the 1930s. Pastoralism involves managing domesticated animals. In nomadic pastoralism , herds of livestock are moved from place to place in search of pasture, fodder, and water. This type of farming is practiced in arid and semi-arid regions of Sahara , Central Asia and some parts of India. In shifting cultivation ,

5040-528: The Amazon Basin. Subsistence farming is practiced to satisfy family or local needs alone, with little left over for transport elsewhere. It is intensively practiced in Monsoon Asia and South-East Asia. An estimated 2.5 billion subsistence farmers worked in 2018, cultivating about 60% of the earth's arable land . Intensive farming is cultivation to maximize productivity, with a low fallow ratio and

5152-547: The Americas. Irrigation , crop rotation , and fertilizers advanced from the 17th century with the British Agricultural Revolution , allowing global population to rise significantly. Since 1900, agriculture in developed nations, and to a lesser extent in the developing world, has seen large rises in productivity as mechanization replaces human labor, and assisted by synthetic fertilizers , pesticides, and selective breeding . The Haber-Bosch method allowed

5264-635: The Canadian Food Inspection Agency, Japan's Ministry of Health and Welfare and the U.S. Food and Drug Administration, the United Nation’s Food and Agriculture Organization, the World Health Organization and the OECD. A quote from FAO, one of the agencies that developed the concept, is useful for defining it: "Substantial equivalence embodies the concept that if a new food or food component is found to be substantially equivalent to an existing food or food component, it can be treated in

5376-571: The Environmental, Public Health, and Consumer Protection pushed forward and adopted a "safety first" principle regarding the case of GMOs, calling for any negative health consequences from GMOs to be held liable. The history of the development of GM crop and GM food regulations in the EU has been challenged to develop a policy environment that is (a) efficient, (b) predicable, (c) accountable, (d) durable or (e) inter- jurisdictionally aligned. However, although

5488-467: The European Union has had relatively strict regulations regarding genetically modified food, Europe is now allowing newer versions of modified maize and other agricultural produce. Also, the level of GMO acceptance in the European Union varies across its countries with Spain and Portugal being more permissive of GMOs than France and the Nordic population. One notable exception however is Sweden. In this country,

Indigenous Australians , long supposed to have been nomadic hunter-gatherers , practiced systematic burning, possibly to enhance natural productivity in fire-stick farming. Scholars have pointed out that hunter-gatherers need a productive environment to support gathering without cultivation. Because

6048-678: The UK the Genetically Modified Organisms (Contained Use) Regulations 2014 provides the framework researchers must follow when using GMOs. Other legislation may be applicable depending on what research is carried out. For workplace safety these include the Health and Safety at Work Act 1974 , the Management of Health and Safety at Work Regulations 1999 , the Carriage of Dangerous Goods legislation and

6160-464: The US. In 1982 the Organisation for Economic Co-operation and Development (OECD) released a report into the potential hazards of releasing genetically modified organisms (GMOs) into the environment as the first transgenic plants were being developed. As the technology improved and genetically organisms moved from model organisms to potential commercial products the US established a committee at

6272-786: The United Nations (FAO) posits that the roles and responsibilities of women in agriculture may be changing – for example, from subsistence farming to wage employment, and from contributing household members to primary producers in the context of male-out-migration. In general, women account for a greater share of agricultural employment at lower levels of economic development, as inadequate education, limited access to basic infrastructure and markets, high unpaid work burden and poor rural employment opportunities outside agriculture severely limit women's opportunities for off-farm work. Women who work in agricultural production tend to do so under highly unfavorable conditions. They tend to be concentrated in

6384-461: The United States is roughly 1.7 times more productive than it was in 1948. Agriculture employed 873 million people in 2021, or 27% of the global workforce, compared with 1 027 million (or 40%) in 2000. The share of agriculture in global GDP was stable at around 4% since 2000–2023. Despite increases in agricultural production and productivity, between 702 and 828 million people were affected by hunger in 2021. Food insecurity and malnutrition can be

6496-534: The United States. Common Market for Eastern and Southern Africa (COMASA) is responsible for assessing the safety of GMOs in most of Africa, although the final decision lies with each individual country. India and China are the two largest producers of genetically modified products in Asia. The Office of Agricultural Genetic Engineering Biosafety Administration (OAGEBA) is responsible for regulation in China, while in India it

6608-530: The annual work-related death toll among agricultural employees is at least 170,000, twice the average rate of other jobs. In addition, incidences of death, injury and illness related to agricultural activities often go unreported.

This constitutes approximately 70% of the global employment of children, and in many countries constitutes the largest percentage of women of any industry. The service sector overtook the agricultural sector as the largest global employer in 2007. In many developed countries, immigrants help fill labor shortages in high-value agriculture activities that are difficult to mechanize. Foreign farm workers from mostly Eastern Europe, North Africa and South Asia constituted around one-third of

6832-532: The basis of their studies, that a number of varieties of GM products (mainly maize and soybeans) are as safe and nutritious as the respective conventional non-GM plant, and those raising still serious concerns, was observed. Moreover, it is worth mentioning that most of the studies demonstrating that GM foods are as nutritional and safe as those obtained by conventional breeding, have been performed by biotechnology companies or associates, which are also responsible of commercializing these GM plants. Anyhow, this represents

Cotton was domesticated in Peru by 3,600 BC. Animals including llamas , alpacas , and guinea pigs were domesticated there. In North America , the indigenous people of the East domesticated crops such as sunflower , tobacco, squash and Chenopodium . Wild foods including wild rice and maple sugar were harvested. The domesticated strawberry

7616-419: The environment in their assessments. When there are varying levels of virulence the regulators base their classification on the highest. Accordingly there are four biosafety levels that a laboratory can fall into, ranging from level 1 (which is suitable for working with agents not associated with disease) to level 4 (working with life threatening agents). Different countries use different nomenclature to describe

The Gunditjmara and other groups developed eel farming and fish trapping systems from some 5,000 years ago. There is evidence of 'intensification' across the whole continent over that period. In two regions of Australia,

8176-600: The government has declared that the GMO definition (according to Directive 2001/18/EC ) stipulates that foreign DNA needs to be present in an organism for it to qualify as a genetically modified organisms. Organisms that have the foreign DNA removed (for example via selective breeding ) therefore do not qualify as GMOs, even if gene editing has been used to make the organism. In June 2014 the European Parliament approved that individual member states are allowed to restrict or ban

8288-422: The greater use of pesticides and fertilizers. Multiple cropping , in which several crops are grown sequentially in one year, and intercropping , when several crops are grown at the same time, are other kinds of annual cropping systems known as polycultures . In subtropical and arid environments, the timing and extent of agriculture may be limited by rainfall, either not allowing multiple annual crops in

8400-425: The growth of GM crops within their territory. Austria, France, Greece, Hungary, Germany, and Luxembourg had prohibited the growth or sale of bioengineered foods in their territory in 2015. Scotland also announced its rejection. By 2015, sixteen countries declared they want to opt out of EU-approved GM crops, including GMOs from major companies like Monsanto , Dow , Syngenta and Pioneer. The U.S. regulatory policy

Most countries that do not allow for GMO cultivation do permit research. Most (85%) of the world's GMO crops are grown in the Americas (North and South). One of the key issues concerning regulators

8624-441: The input of nutrients (fertilizer or manure ) and some manual pest control . Annual cultivation is the next phase of intensity in which there is no fallow period. This requires even greater nutrient and pest control inputs. Further industrialization led to the use of monocultures , when one cultivar is planted on a large acreage. Because of the low biodiversity , nutrient use is uniform and pests tend to build up, necessitating

8736-547: The levels and can have different requirements for what can be done at each level. In Europe the use of living GMOs are regulated by the European Directive on the contained use of genetically modified microorganisms (GMMs). The regulations require risk assessments before use of any contained GMOs is started and assurances that the correct controls are in place. It provides the minimal standards for using GMMs, with individual countries allowed to enforce stronger controls. In

8848-412: The lower yield associated with organic farming and its impact on global food security . Recent mainstream technological developments include genetically modified food . By 2015, the agricultural output of China was the largest in the world, followed by the European Union, India and the United States. Economists measure the total factor productivity of agriculture, according to which agriculture in

8960-474: The most stringent GMO regulations in the world. All GMOs, along with irradiated food , are considered "new food" and subject to extensive, case-by-case, science-based food evaluation by the European Food Safety Authority (EFSA). The criteria for authorization fall in four broad categories: "safety", "freedom of choice", "labelling", and "traceability". The European Parliament's Committee on

9072-562: The non-GMO version of the organism, although they are more severe. In many countries now the regulations are diverging, even though many of the risks and procedures are similar. Sometimes even different agencies are responsible, notably in the Netherlands where the Ministry of the Environment covers GMOs and the Ministry of Social Affairs covers the human pathogens they are derived from. There

9184-437: The philosophy and culture of the farmer. Shifting cultivation (or slash and burn ) is a system in which forests are burnt, releasing nutrients to support cultivation of annual and then perennial crops for a period of several years. Then the plot is left fallow to regrow forest, and the farmer moves to a new plot, returning after many more years (10–20). This fallow period is shortened if population density grows, requiring

9296-414: The poorest countries, where alternative livelihoods are not available, and they maintain the intensity of their work in conditions of climate-induced weather shocks and in situations of conflict. Women are less likely to participate as entrepreneurs and independent farmers and are engaged in the production of less lucrative crops. The gender gap in land productivity between female- and male managed farms of

9408-440: The production of fish for human consumption in confined operations, is one of the fastest growing sectors of food production, growing at an average of 9% a year between 1975 and 2007. During the second half of the 20th century, producers using selective breeding focused on creating livestock breeds and crossbreeds that increased production, while mostly disregarding the need to preserve genetic diversity . This trend has led to

9520-588: The products." For a genetically modified organism to be approved for release in the U.S., it must be assessed under the Plant Protection Act by the Animal and Plant Health Inspection Service (APHIS) agency within the USDA and may also be assessed by the FDA and the EPA, depending on the intended use of the organism. The USDA evaluate the plants potential to become weeds, the FDA reviews plants that could enter or alter

9632-577: The public are much less likely than scientists to perceive GM foods as safe. The legal and regulatory status of GM foods varies by country, with some nations banning or restricting them, and others permitting them with widely differing degrees of regulation. There is no evidence to support the idea that the consumption of approved GM food has a detrimental effect on human health. Some scientists and advocacy groups, such as Greenpeace and World Wildlife Fund , have however called for additional and more rigorous testing for GM food. The development of

9744-565: The publication of the report ‘Strategies for Assessing the Safety of Foods Produced by Biotechnology’ in 1991. Building on that, an international consensus was reached by the OECD’s Group of National Experts on Safety in Biotechnology, for assessing biotechnology in general, including field testing GM crops. That Group met again in Bergen, Norway in 1992 and reached consensus on principles for evaluating

9856-451: The regulation of GMOs than in Europe, with the FDA and USDA only looking over pesticide and plant health facets of GMOs. Despite the overall global increase in the production in GMOs, the European Union has still stalled GMOs fully integrating into its food supply. This has definitely affected various countries, including the United States, when trading with the EU. The European Union enacted regulatory laws in 2003 that provided possibly

9968-511: The regulators will generally not require further food safety testing. However, if the product has no natural equivalent, or shows significant differences from the unmodified food, or for other reasons that regulators may have (for instance, if a gene produces a protein that had not been a food component before), the regulators may require that further safety testing be carried out. A 2003 review in Trends in Biotechnology identified seven main parts of

10080-438: The requirements for the international trade of GMOs between countries that are signatories to it. Any shipments contain genetically modified organisms that are intended to be used as feed, food or for processing must be identified and a list of the transgenic events be available. "Substantial equivalence" is a starting point for the safety assessment for GM foods that is widely used by national and international agencies—including

10192-477: The result of conflict, climate extremes and variability and economic swings. It can also be caused by a country's structural characteristics such as income status and natural resource endowments as well as its political economy. Pesticide use in agriculture went up 62% between 2000 and 2021, with the Americas accounting for half the use in 2021. The International Fund for Agricultural Development posits that an increase in smallholder agriculture may be part of

10304-784: The role that individuals and organizations engaged in agriculture should play. In the United States, agriculture has been identified by the National Institute for Occupational Safety and Health as a priority industry sector in the National Occupational Research Agenda to identify and provide intervention strategies for occupational health and safety issues. In the European Union, the European Agency for Safety and Health at Work has issued guidelines on implementing health and safety directives in agriculture, livestock farming, horticulture, and forestry. The Agricultural Safety and Health Council of America (ASHCA) also holds

10416-417: The safety assessment of genetically modified plants" (PDF) . Environment International . 37 (4): 734–742. doi : 10.1016/j.envint.2011.01.003 . PMID   21296423 . In spite of this, the number of studies specifically focused on safety assessment of GM plants is still limited. However, it is important to remark that for the first time, a certain equilibrium in the number of research groups suggesting, on

10528-402: The safety of GM food; its report, ‘The safety evaluation of foods derived by modern technology – concepts and principles’ was published in 1993. That report recommends conducting the safety assessment of a GM food on a case-by-case basis through comparison to an existing food with a long history of safe use. This basic concept has been refined in subsequent workshops and consultations organized by

10640-474: The salaried agricultural workforce in Spain, Italy, Greece and Portugal in 2013. In the United States of America, more than half of all hired farmworkers (roughly 450,000 workers) were immigrants in 2019, although the number of new immigrants arriving in the country to work in agriculture has fallen by 75 percent in recent years and rising wages indicate this has led to a major labor shortage on U.S. farms. Around

10752-415: The same manner with respect to safety (i.e., the food or food component can be concluded to be as safe as the conventional food or food component)". The concept of substantial equivalence also recognises the fact that existing foods often contain toxic components (usually called antinutrients ) and are still able to be consumed safely—in practice there is some tolerable chemical risk taken with all foods, so

10864-439: The same size is 24 percent. On average, women earn 18.4 percent less than men in wage employment in agriculture; this means that women receive 82 cents for every dollar earned by men. Progress has been slow in closing gaps in women's access to irrigation and in ownership of livestock, too. Women in agriculture still have significantly less access than men to inputs, including improved seeds, fertilizers and mechanized equipment. On

10976-488: The solution to concerns about food prices and overall food security , given the favorable experience of Vietnam. Agriculture provides about one-quarter of all global employment, more than half in sub-Saharan Africa and almost 60 percent in low-income countries. As countries develop, other jobs have historically pulled workers away from agriculture, and labor-saving innovations increase agricultural productivity by reducing labor requirements per unit of output. Over time,

11088-400: The synthesis of ammonium nitrate fertilizer on an industrial scale, greatly increasing crop yields and sustaining a further increase in global population. Modern agriculture has raised or encountered ecological, political, and economic issues including water pollution , biofuels , genetically modified organisms , tariffs and farm subsidies , leading to alternative approaches such as

11200-655: The transition from hunter-gatherer to agricultural societies indicate an initial period of intensification and increasing sedentism ; examples are the Natufian culture in the Levant , and the Early Chinese Neolithic in China. Then, wild stands that had previously been harvested started to be planted, and gradually came to be domesticated. In Eurasia, the Sumerians started to live in villages from about 8,000 BC, relying on

11312-401: The unmodified food. The manufacturer's data is then assessed by a regulatory agency, such as the U.S. Food and Drug Administration . That data, along with data on the genetic modification itself and resulting proteins (or lack of protein), is submitted to regulators. If regulators determine that the submitted data show no significant difference between the modified and unmodified products, then

11424-656: The wild aurochs in the areas of modern Turkey and Pakistan some 10,500 years ago. Pig production emerged in Eurasia, including Europe, East Asia and Southwest Asia, where wild boar were first domesticated about 10,500 years ago. In the Andes of South America, the potato was domesticated between 10,000 and 7,000 years ago, along with beans, coca , llamas , alpacas , and guinea pigs . Sugarcane and some root vegetables were domesticated in New Guinea around 9,000 years ago. Sorghum

11536-744: The world consist of fewer than 2 hectares (4.9 acres), and take up only around 12% of all agricultural land. Farms and farming greatly influence rural economics and greatly shape rural society , affecting both the direct agricultural workforce and broader businesses that support the farms and farming populations. The major agricultural products can be broadly grouped into foods , fibers , fuels , and raw materials (such as rubber ). Food classes include cereals ( grains ), vegetables , fruits , cooking oils , meat , milk , eggs , and fungi . Global agricultural production amounts to approximately 11 billion tonnes of food, 32 million tonnes of natural fibers and 4 billion m of wood. However, around 14% of

11648-774: The world's agricultural land is seriously degraded. In recent years there has been a backlash against the environmental effects of conventional agriculture, resulting in the organic , regenerative , and sustainable agriculture movements. One of the major forces behind this movement has been the European Union , which first certified organic food in 1991 and began reform of its Common Agricultural Policy (CAP) in 2005 to phase out commodity-linked farm subsidies, also known as decoupling . The growth of organic farming has renewed research in alternative technologies such as integrated pest management , selective breeding, and controlled-environment agriculture . There are concerns about

11760-664: The world's food is lost from production before reaching the retail level. Modern agronomy , plant breeding , agrochemicals such as pesticides and fertilizers , and technological developments have sharply increased crop yields , but also contributed to ecological and environmental damage . Selective breeding and modern practices in animal husbandry have similarly increased the output of meat, but have raised concerns about animal welfare and environmental damage. Environmental issues include contributions to climate change , depletion of aquifers , deforestation , antibiotic resistance , and other agricultural pollution . Agriculture

11872-481: The world, women make up a large share of the population employed in agriculture. This share is growing in all developing regions except East and Southeast Asia where women already make up about 50 percent of the agricultural workforce. Women make up 47 percent of the agricultural workforce in sub-Saharan Africa, a rate that has not changed significantly in the past few decades. However, the Food and Agriculture Organization of

11984-495: The world. In the 20th century, industrial agriculture based on large-scale monocultures came to dominate agricultural output. As of 2021 , small farms produce about one-third of the world's food, but large farms are prevalent. The largest 1% of farms in the world are greater than 50 hectares (120 acres) and operate more than 70% of the world's farmland. Nearly 40% of agricultural land is found on farms larger than 1,000 hectares (2,500 acres). However, five of every six farms in

12096-621: The world. Production is listed in millions of metric tons, based on FAO estimates. Animal husbandry is the breeding and raising of animals for meat, milk, eggs , or wool , and for work and transport. Working animals , including horses, mules , oxen , water buffalo , camels, llamas, alpacas, donkeys, and dogs, have for centuries been used to help cultivate fields, harvest crops, wrangle other animals, and transport farm products to buyers. Livestock production systems can be defined based on feed source, as grassland-based, mixed, and landless. As of 2010 , 30% of Earth's ice- and water-free area

12208-444: Was a key factor in the rise of sedentary human civilization , whereby farming of domesticated species created food surpluses that enabled people to live in the cities. While humans started gathering grains at least 105,000 years ago, nascent farmers only began planting them around 11,500 years ago. Sheep, goats, pigs, and cattle were domesticated around 10,000 years ago. Plants were independently cultivated in at least 11 regions of

12320-621: Was domesticated by the Mayo Chinchipe of the upper Amazon around 3,000 BC. The turkey was probably domesticated in Mexico or the American Southwest. The Aztecs developed irrigation systems, formed terraced hillsides, fertilized their soil, and developed chinampas or artificial islands. The Mayas used extensive canal and raised field systems to farm swampland from 400 BC. In South America agriculture may have begun about 9000 BC with

12432-548: Was domesticated in the Sahel region of Africa by 7,000 years ago. Cotton was domesticated in Peru by 5,600 years ago, and was independently domesticated in Eurasia. In Mesoamerica , wild teosinte was bred into maize (corn) from 10,000 to 6,000 years ago. The horse was domesticated in the Eurasian Steppes around 3500 BC. Scholars have offered multiple hypotheses to explain the historical origins of agriculture. Studies of

12544-584: Was used for producing livestock, with the sector employing approximately 1.3 billion people. Between the 1960s and the 2000s, there was a significant increase in livestock production, both by numbers and by carcass weight, especially among beef, pigs and chickens, the latter of which had production increased by almost a factor of 10. Non-meat animals, such as milk cows and egg-producing chickens, also showed significant production increases. Global cattle, sheep and goat populations are expected to continue to increase sharply through 2050. Aquaculture or fish farming,
