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
270-470: 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

Animals (domesticated and wild) use as many types of grasses that have adapted to different locations as their main source of nutrients. Humans eat thousands of plant species; there may be as many as 75,000 edible species of angiosperms , of which perhaps 7,000 are often eaten. Plants can be processed into breads, pasta, cereals, juices and jams or raw ingredients such as sugar, herbs, spices and oils can be extracted. Oilseeds are pressed to produce rich oils – sunflower , flaxseed , rapeseed (including canola oil ) and sesame . Many plants and animals have coevolved in such

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
630-583: A high protein, fibre, vitamin E and B content. Seeds are a good source of food for animals because they are abundant and contain fibre and healthful fats, such as omega-3 fats . Complicated chemical interactions can enhance or depress bioavailability of certain nutrients. Phytates can prevent the release of some sugars and vitamins. Animals that only eat plants are called herbivores , with those that mostly just eat fruits known as frugivores , leaves, while shoot eaters are folivores (pandas) and wood eaters termed xylophages (termites). Frugivores include
720-444: 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

Not all mammals share the same tastes: some rodents can taste starch , cats cannot taste sweetness, and several carnivores (including hyenas , dolphins, and sea lions) have lost the ability to sense up to four of the five taste modalities found in humans. Food is broken into nutrient components through digestive process. Proper digestion consists of mechanical processes ( chewing , peristalsis ) and chemical processes ( digestive enzymes and microorganisms ). The digestive systems of herbivores and carnivores are very different as plant matter

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
1170-546: A source of food for protozoa, who in turn provide a source of food for other organisms such as small invertebrates. Other organisms that feed on bacteria include nematodes, fan worms, shellfish and a species of snail. In the marine environment, plankton (which includes bacteria , archaea , algae , protozoa and microscopic fungi ) provide a crucial source of food to many small and large aquatic organisms. Without bacteria, life would scarcely exist because bacteria convert atmospheric nitrogen into nutritious ammonia . Ammonia

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
2070-402: Is caused by acids , such as vinegar in alcoholic beverages. Sour foods include citrus, specifically lemons and limes . Sour is evolutionarily significant as it can signal a food that may have gone rancid due to bacteria. Saltiness is the taste of alkali metal ions such as sodium and potassium. It is found in almost every food in low to moderate proportions to enhance flavor. Bitter taste
2160-444: 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

Eggs laid by birds and other animals are eaten and bees produce honey , a reduced nectar from flowers that is used as a popular sweetener in many cultures. Some cultures consume blood , such as in blood sausage , as a thickener for sauces, or in a cured , salted form for times of food scarcity, and others use blood in stews such as jugged hare . Animals, specifically humans, typically have five different types of tastes: sweet , sour , salty , bitter , and umami . The differing tastes are important for distinguishing between foods that are nutritionally beneficial and those which may contain harmful toxins. As animals have evolved ,
2340-502: Is harder to digest. Carnivores mouths are designed for tearing and biting compared to the grinding action found in herbivores. Herbivores however have comparatively longer digestive tracts and larger stomachs to aid in digesting the cellulose in plants. According to the World Health Organization (WHO), about 600 million people worldwide get sick and 420,000 die each year from eating contaminated food. Diarrhea

A 2003 World Health Organization (WHO) report concluded that about 30% of reported food poisoning outbreaks in the WHO European Region occur in private homes. According to
2700-738: Is the most energy-dense component. Some inorganic (non-food) elements are also essential for plant and animal functioning. Human food can be classified in various ways, either by related content or by how it is processed. The number and composition of food groups can vary. Most systems include four basic groups that describe their origin and relative nutritional function: Vegetables and Fruit, Cereals and Bread, Dairy, and Meat. Studies that look into diet quality group food into whole grains/cereals, refined grains/cereals, vegetables, fruits, nuts, legumes, eggs, dairy products, fish, red meat, processed meat, and sugar-sweetened beverages. The Food and Agriculture Organization and World Health Organization use

Scholars have pointed out that hunter-gatherers need a productive environment to support gathering without cultivation. Because
4230-793: 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

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
6570-439: 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
6660-428: The society's annual functions. In 1876, the society had an income of $ 41,210 (equivalent to $ 1,180,000 in 2023). Of that, $ 15,086 ($ 432,000 in 2023) was from the state fair. In 1900, as a result of a change to a state law, the New York State Agricultural Society was mandated to receive $ 20,000 ($ 732,000 in 2023) in premiums "of all moneys appropriated for the promotion of agriculture in any one year". The following
6750-488: 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,
6840-400: 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
6930-448: The tastes that provide the most energy are the most pleasant to eat while others are not enjoyable, although humans in particular can acquire a preference for some substances which are initially unenjoyable. Water, while important for survival, has no taste. Sweetness is almost always caused by a type of simple sugar such as glucose or fructose , or disaccharides such as sucrose , a molecule combining glucose and fructose. Sourness
7020-523: The top. Other aspects of the web include detrovores (that eat detritis ) and decomposers (that break down dead organisms). Primary producers include algae, plants, bacteria and protists that acquire their energy from sunlight. Primary consumers are the herbivores that consume the plants, and secondary consumers are the carnivores that consume those herbivores. Some organisms, including most mammals and birds, diet consists of both animals and plants, and they are considered omnivores. The chain ends with
7110-679: 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
7200-671: 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
7290-744: 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
7380-781: 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
7470-403: The world's crops are used to feed humans (55 percent), with 36 percent grown as animal feed and 9 percent for biofuels . Fungi and bacteria are also used in the preparation of fermented foods like bread , wine , cheese and yogurt . During photosynthesis , energy from the sun is absorbed and used to transform water and carbon dioxide in the air or soil into oxygen and glucose. The oxygen
7560-664: 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
7650-435: 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
7740-495: 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
7830-621: 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
7920-640: 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
8010-560: 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
8100-584: 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,
