242-810: 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
363-795: A 23,000-years-old fisher-hunter-gatherers' camp on the shore of the Sea of Galilee , Northern Israel , provides the earliest evidence for the use of composite cereal harvesting tools. The Ohalo site is at the junction of the Upper Paleolithic and the Early Epipaleolithic , and has been attributed to both periods. The wear traces indicate that tools were used for harvesting near-ripe semi-green wild cereals, shortly before grains are ripe and disperse naturally. The studied tools were not used intensively, and they reflect two harvesting modes: flint knives held by hand and inserts hafted in
484-470: 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
605-623: A corridor between the millet and rice cultivation centres where both rice and millet were cultivated. At around 5,500 to 4,000 BP, there was increasing migration into Taiwan from the early Austronesian Dapenkeng culture , bringing rice and millet cultivation technology with them. During this period, there is evidence of large settlements and intensive rice cultivation in Taiwan and the Penghu Islands , which may have resulted in overexploitation . Bellwood (2011) proposes that this may have been
726-602: A different problem: most of the wild seeds do not germinate in the first year; the first evidence of lentil domestication, breaking dormancy in their first year, appears in the early Neolithic at Jerf el Ahmar (in modern Syria), and lentils quickly spread south to the Netiv HaGdud site in the Jordan Valley . The process of domestication allowed the founder crops to adapt and eventually become larger, more easily harvested, more dependable in storage and more useful to
847-405: A food source, also had to be taken into account. Besides being a direct source of food, certain animals could provide leather, wool, hides, and fertilizer. Some of the earliest domesticated animals included dogs ( East Asia , about 15,000 years ago), sheep, goats, cows, and pigs. West Asia was the source for many animals that could be domesticated, such as sheep, goats and pigs. This area was also

The finds shed new light on cereal harvesting techniques some 8,000 years before the Natufian and 12,000 years before the establishment of sedentary farming communities in the Near East. Furthermore, the new finds accord well with evidence for the earliest ever cereal cultivation at the site and the use of stone-made grinding implements. Agriculture appeared first in West Asia about 2,000 years later, around 10,000–9,000 years ago. The region
1089-664: 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
1210-444: 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

Both shared the temperate climate ideal for the first agricultural settings, and both were near a number of easily domesticable plant and animal species. In areas where continents aligned north–south such as the Americas and Africa, crops—and later domesticated animals—could not spread across tropical zones. Agriculture in Neolithic China can be separated into two broad regions, Northern China and Southern China. The agricultural centre in northern China

Some of the pioneering attempts failed at first and crops were abandoned, sometimes to be taken up again and successfully domesticated thousands of years later: rye , tried and abandoned in Neolithic Anatolia , made its way to Europe as weed seeds and was successfully domesticated in Europe, thousands of years after the earliest agriculture. Wild lentils presented
1936-404: 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
2057-492: 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

2541-810: Is a highly resilient crop, able to grow in varied and marginal environments, such as in regions of high altitude and latitude. Archaeobotanical evidence shows that barley had spread throughout Eurasia by 2,000 BCE. To further elucidate the routes by which barley cultivation was spread through Eurasia, genetic analysis was used to determine genetic diversity and population structure in extant barley taxa. Genetic analysis shows that cultivated barley spread through Eurasia via several different routes, which were most likely separated in both time and space. When hunter-gathering began to be replaced by sedentary food production it became more efficient to keep animals close at hand. Therefore, it became necessary to bring animals permanently to their settlements, although in many cases there

Once agriculture started gaining momentum, around 9000 BP, human activity resulted in the selective breeding of cereal grasses (beginning with emmer , einkorn and barley ), and not simply of those that favoured greater caloric returns through larger seeds. Plants with traits such as small seeds or bitter taste were seen as undesirable. Plants that rapidly shed their seeds on maturity tended not to be gathered at harvest, therefore not stored and not seeded

In subtropical and arid environments, the timing and extent of agriculture may be limited by rainfall, either not allowing multiple annual crops in
9196-473: The health of early agriculturalists and their domesticated livestock would have been increased numbers of parasites and disease-bearing pests associated with human waste and contaminated food and water supplies. Fertilizers and irrigation may have increased crop yields but also would have promoted proliferation of insects and bacteria in the local environment while grain storage attracted additional insects and rodents . The term 'neolithic revolution'
9317-563: The human population. Selectively propagated figs , wild barley and wild oats were cultivated at the early Neolithic site of Gilgal I , where in 2006 archaeologists found caches of seeds of each in quantities too large to be accounted for even by intensive gathering , at strata datable to c. 11,000 years ago. Some of the plants tried and then abandoned during the Neolithic period in the Ancient Near East, at sites like Gilgal, were later successfully domesticated in other parts of
9438-638: The impetus of the Austronesian expansion which started with the migration of the Austronesian-speakers from Taiwan to the Philippines at around 5,000 BP. Austronesians carried rice cultivation technology to Island Southeast Asia along with other domesticated species. The new tropical island environments also had new food plants that they exploited. They carried useful plants and animals during each colonization voyage, resulting in
9559-441: 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
9680-476: 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
9801-602: The lowlands may have been even earlier. CSIRO has found evidence that taro was introduced into the Solomon Islands for human use, from 28,000 years ago, making taro the earliest cultivated crop in the world. It seems to have resulted in the spread of the Trans–New Guinea languages from New Guinea east into the Solomon Islands and west into Timor and adjacent areas of Indonesia . This seems to confirm
9922-437: 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
10043-414: 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
10164-410: The population expanded and communities developed specialized workers and more advanced tools. The process was not as linear as was once thought, but a more complicated effort, which was undertaken by different human populations in different regions in many different ways. One of the world's most important crops, barley , was domesticated in the Near East around 11,000 years ago (c. 9,000 BCE). Barley
10285-440: 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
10406-401: The production of surplus food. Other developments that are found very widely during this era are the domestication of animals , pottery , polished stone tools, and rectangular houses. In many regions, the adoption of agriculture by prehistoric societies caused episodes of rapid population growth, a phenomenon known as the Neolithic demographic transition . These developments, sometimes called
10527-545: The rapid introduction of domesticated and semi-domesticated species throughout Oceania . They also came into contact with the early agricultural centres of Papuan -speaking populations of New Guinea as well as the Dravidian -speaking regions of South India and Sri Lanka by around 3,500 BP. They acquired further cultivated food plants like bananas and pepper from them, and in turn introduced Austronesian technologies like wetland cultivation and outrigger canoes . During
10648-429: The region a large advantage in cultural and economic development. As the climate in the Middle East changed and became drier, many of the farmers were forced to leave, taking their domesticated animals with them. It was this massive emigration from the Middle East that later helped distribute these animals to the rest of Afroeurasia . This emigration was mainly on an east–west axis of similar climates, as crops usually have
10769-622: The rest of Eurasia and North Africa, while it did not reach through the north–south axis of Africa to reach the Mediterranean climates of South Africa , where temperate crops were successfully imported by ships in the last 500 years. Similarly, the African Zebu of central Africa and the domesticated bovines of the fertile-crescent – separated by the dry sahara desert – were not introduced into each other's region. Use-wear analysis of five glossed flint blades found at Ohalo II ,
10890-477: 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
11011-509: The rise of civilizations and technological evolutions . However, higher population and food abundance did not necessarily correlate with improved health. Reliance on a very limited variety of staple crops can adversely affect health even while making it possible to feed more people. Maize is deficient in certain essential amino acids ( lysine and tryptophan ) and is a poor source of iron . The phytic acid it contains may inhibit nutrient absorption . Other factors that likely affected
11132-874: 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
11253-478: 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
11374-439: 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

11616-983: The skeletal remains in graves at Mehrgarh bear strong resemblance to those at Ali Kosh in the Zagros Mountains of southern Iran. Despite their scarcity, the Carbon-14 and archaeological age determinations for early Neolithic sites in Southern Asia exhibit remarkable continuity across the vast region from the Near East to the Indian Subcontinent, consistent with a systematic eastward spread at a speed of about 0.65 km/yr. The most prominent of several theories (not mutually exclusive) as to factors that caused populations to develop agriculture include: Agriculture Agriculture encompasses crop and livestock production, aquaculture , and forestry for food and non-food products. Agriculture
11737-488: 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,
11858-481: The speed of 0.6–1.3 km/yr (at 95% confidence level). Since the original human expansions out of Africa 200,000 years ago, different prehistoric and historic migration events have taken place in Europe. Considering that the movement of the people implies a consequent movement of their genes, it is possible to estimate the impact of these migrations through the genetic analysis of human populations. Agricultural and husbandry practices originated 10,000 years ago in
11979-400: 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
12100-454: The theories of Carl Sauer who, in "Agricultural Origins and Dispersals", suggested as early as 1952 that this region was a centre of early agriculture. Archaeologists trace the emergence of food-producing societies in the Levantine region of southwest Asia at the close of the last glacial period around 12,000 BCE, and developed into a number of regionally distinctive cultures by the eighth millennium BCE. Remains of food-producing societies in
12221-624: 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
12342-671: 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
12463-744: 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
12584-781: 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
12705-664: 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
12826-485: 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
12947-537: The world. Once early farmers perfected their agricultural techniques like irrigation (traced as far back as the 6th millennium BCE in Khuzistan ), their crops yielded surpluses that needed storage. Most hunter-gatherers could not easily store food for long due to their migratory lifestyle, whereas those with a sedentary dwelling could store their surplus grain. Eventually granaries were developed that allowed villages to store their seeds longer. So with more food,
13068-495: 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
13189-621: 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
13310-630: Was broomcorn millet , domesticated in East Asia. The earliest evidence of cheese -making dates to 5500 BCE in Kujawy , Poland . The diffusion across Europe, from the Aegean to Britain, took about 2,500 years (8500–6000 BP). The Baltic region was penetrated a bit later, around 5500 BP, and there was also a delay in settling the Pannonian plain . In general, colonization shows a "saltatory" pattern, as
13431-419: Was a distinction between relatively sedentary farmers and nomadic herders. The animals' size, temperament, diet, mating patterns, and life span were factors in the desire and success in domesticating animals. Animals that provided milk, such as cows and goats, offered a source of protein that was renewable and therefore quite valuable. The animal's ability as a worker (for example ploughing or towing), as well as
13552-444: 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
13673-516: Was also domesticated in northern China 4,500 years ago. Orange and peach also originated in China, being cultivated c. 2500 BCE . ) The agricultural centres in southern China are clustered around the Yangtze River basin. Rice was domesticated in this region, together with the development of paddy field cultivation, between 13,500 and 8,200 years ago. There are two possible centres of domestication for rice. The first
13794-640: 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
13915-560: 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
14036-488: Was first studied quantitatively in the 1970s, when a sufficient number of Carbon 14 age determinations for early Neolithic sites had become available. In 1973, Ammerman and Cavalli-Sforza discovered a linear relationship between the age of an Early Neolithic site and its distance from the conventional source in the Near East ( Jericho ), demonstrating that the Neolithic spread at an average speed of about 1 km/yr. More recent studies (2005) confirm these results and yield
14157-665: Was introduced to Europe via western Anatolia. All Neolithic sites in Europe contain ceramics , and contain the plants and animals domesticated in Southwest Asia: einkorn , emmer , barley , lentils , pigs , goats , sheep , and cattle . Genetic data suggest that no independent domestication of animals took place in Neolithic Europe, and that all domesticated animals were originally domesticated in Southwest Asia. The only domesticate not from Southwest Asia
14278-476: Was invented by V. Gordon Childe in his book Man Makes Himself (1936). Childe introduced it as the first in a series of agricultural revolutions in Middle Eastern history, calling it a "revolution" to denote its significance, the degree of change to communities adopting and refining agricultural practices. The beginning of this process in different regions has been dated from 10,000 to 8,000 BCE in
14399-524: Was the centre of domestication for three cereals (einkorn wheat, emmer wheat and barley), four legumes (lentil, pea, bitter vetch and chickpea), and flax. Domestication was a slow process that unfolded across multiple regions, and was preceded by centuries if not millennia of pre-domestication cultivation. Finds of large quantities of seeds and a grinding stone at the Epipalaeolithic site of Ohalo II , dating to around 19,400 BP, has shown some of
14520-584: 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,
14641-794: Was well-balanced though heavily dependent on what the environment could provide each season. In contrast, because the surplus and plannable supply of food provided by agriculture made it possible to support larger population groups, agriculturalists lived in more permanent dwellings in more densely populated settlements than what could be supported by a hunter-gatherer lifestyle. The agricultural communities' seasonal need to plan and coordinate resource and manpower encouraged division of labour , which gradually led to specialization of labourers and complex societies . The subsequent development of trading networks to exchange surplus commodities and services brought agriculturalists into contact with outside groups, which promoted cultural exchanges that led to
