The Agricultural Revolution: 12,000 Years That Changed Human History
Human Life Before Agriculture
Homo sapiens has existed for approximately 300,000 years. The Agricultural Revolution, which involved the systematic domestication of plants and animals, began approximately 12,000 years ago. Before the Agricultural Revolution, humans sustained themselves by hunting, fishing, and gathering wild plants.
Hunter-gatherer communities had to learn about animal behaviour, plant growing seasons, seasonal changes, water sources, and the ecological characteristics of the regions they inhabited. Before the Agricultural Revolution, humans could use fire, develop hunting techniques, systematically gather wild plants, grind grains, and store food. In other words, humans had accumulated the knowledge that made the domestication of plants and animals possible during the hunter-gatherer period.
Human communities before the Agricultural Revolution are often thought to have been constantly on the move. Indeed, many hunter-gatherer communities moved according to the seasons and the locations where resources were available. However, patterns of mobility could vary across communities and periods.
At the Ohalo II site on the shores of the Sea of Galilee in Israel, huts, hearths, plant remains, and grinding stones dating to approximately 23,000 years ago have been found. At Kharaneh IV in Jordan, traces of settlement dating back approximately 20,000 years have been identified. These were not agricultural societies. However, they show that different ways of life between mobility and sedentism had emerged thousands of years before the Agricultural Revolution.
Stone structures, grinding tools, storage practices, and burial grounds are found among Natufian communities that lived in the Levant region of the eastern Mediterranean between approximately 12,500 and 9500 BCE. Before the transition to agriculture, some Natufian communities lived in the same places for extended periods and made use of wild cereals. The term Natufian emerged from modern archaeological classification.
The traditional narrative holds that humans first discovered agriculture and then abandoned a nomadic way of life. However, archaeological evidence reveals traces of a transition to settled life before agriculture in some regions.
Humans lived by hunting and gathering for hundreds of thousands of years. Why, then, did they begin systematically domesticating plants and animals in some parts of the world approximately 12,000 years ago? Why did this transformation not occur everywhere in the world at the same time?
Why Did Humans Begin Producing Food?
What changed with the Agricultural Revolution? Humans shifted from gathering plants to cultivating them. They turned from hunting wild animals to managing herds and controlling their reproduction. Subsistence began to shift from obtaining food to producing plants and animals through human intervention.
Archaeological findings show that the transition from hunting and gathering to agricultural production took centuries and, in some regions, even millennia. The consequences of the Agricultural Revolution were revolutionary, but its development was largely evolutionary.
With the end of the last Ice Age, the world entered the Holocene approximately 11,700 years ago. More stable climatic conditions changed vegetation and available food resources in some regions. In areas where wild cereals were abundant, new opportunities emerged for systematically gathering and later cultivating these resources.
Treating climate change as the sole cause of the Agricultural Revolution is wholly inadequate. If the Agricultural Revolution had resulted only from changing climatic conditions, human communities in other regions exposed to similar climatic changes could also have adopted agriculture at approximately the same time.
In the Fertile Crescent, the domestication of cereals such as wheat and barley and animals such as sheep and goats began to emerge between approximately 10,000 and 8500 BCE. In China, different production systems based on rice and millet developed. In New Guinea, people began cultivating plants such as taro, yams, and bananas. In Mesoamerica, squash, maize, and beans were domesticated at different times, as were potatoes, quinoa, and other local species in the Andes. In Africa, systems based on species such as sorghum and pearl millet developed.
The transition to agriculture did not occur through a sudden discovery of farming. Over time, humans transformed hundreds of thousands of years of knowledge about nature into the Agricultural Revolution. Under what conditions, then, did the production of particular plants and animals become a more important source of subsistence alongside hunting and gathering? What conditions drove humans towards the Agricultural Revolution?
The Agricultural Revolution was not an inevitable stage of progress. Hunting and gathering was a successful way of life under certain ecological conditions. Environmental and demographic conditions were changing. As noted above, humans had already accumulated a body of knowledge. Under these conditions, local plant and animal species made it possible for new forms of production to emerge in particular regions.
An important advantage of these new forms of production was their ability to directly affect the quantity of food available. Cultivating wild cereals rather than gathering them made it possible to produce more food within a given area and store part of the harvest. Managing animal herds meant intervening in animal numbers and reproduction rather than hunting. Humans thus began to gain the ability to manage the quantity of food they needed.
These developments did not necessarily mean that humans ate better, worked less, or lived better lives. Agriculture could increase the quantity of food that could be produced in a particular region and the number of people it could feed. Humans began to change from beings who obtained food into beings who intervened directly in the quantity and reproduction of food resources. The Agricultural Revolution represented a change in scale.
Agriculture and Settled Life
For the reasons explained above, the transition to settled life cannot be regarded as a sudden outcome of the Agricultural Revolution. At the same time, the existence of settlements before agriculture should not obscure the importance of settled life for farming. The spread of agricultural production fundamentally changed the economic significance of settling down.
Agriculture required preparing the soil, waiting for crops to grow, harvesting, and storing the produce. Animal husbandry also required protecting and feeding herds and monitoring reproduction. Humans were no longer moving to wherever food was available, as they had during the hunter-gatherer period. Producing food was changing the nature and organization of labour.
Hunting and gathering also required planning. In agricultural production, however, a much more systematic approach was necessary for labour expended today to yield results months later. Sowing, tending, harvesting, and storage were the stages of this new period. Agricultural production meant becoming tied to the land and an annual cycle.
While agriculture encouraged settled life, settled life also strengthened agriculture. Living in the same region for longer periods created needs for storage facilities, houses, communal spaces, and production tools. The characteristics of plants could be observed across generations. Settled life and agricultural production thus became a mutually reinforcing process.
We now know that Göbekli Tepe began to emerge around 9600 BCE. Its monumental structures show that large groups of people could organize themselves and direct their labour towards collective activities. Göbekli Tepe has prompted further questioning of the simple narrative of “first agriculture, then settlement, followed by complex social organization.” In other words, communities undergoing the transition to agriculture could undertake collective activities even before developed agricultural societies emerged.
Tell es-Sultan in Jericho is also an important example of early settled life. In subsequent millennia, settlements such as Çayönü, Ain Ghazal, and Çatalhöyük demonstrated the extent of the relationship between agricultural production and settled life. In particular, Çatalhöyük, which developed from approximately 7100 BCE onwards, provides evidence of a large Neolithic community in which thousands of people could live in the same settlement.
When analysing the process that began before the Agricultural Revolution, it is important to remember that a large settlement and a city are not the same thing. Cities such as Uruk, which emerged in Mesopotamia thousands of years later, would feature very different institutional arrangements, including specialized occupations, administrative structures, centralized political organization, and the collection of surplus produce. It must therefore be emphasized that a process of transformation spanning thousands of years separated the Agricultural Revolution from urbanization.
The transition to agriculture began to take clearer shape around the tenth millennium BCE. The emergence of the first states and urban forms of political organization in Mesopotamia dates to the fourth and third millennia BCE. Agriculture did not immediately or inevitably create states or cities. It established some of the material conditions that would make them possible.
One of the most fundamental of these conditions was the ability of a given region to support more people. Under agricultural production, an area of the same size could sustain a much denser population than under hunting and gathering. As settlement, the intensification of production, and food storage created mutually reinforcing cycles, the scale of human communities also began to change. However, a society’s ability to feed more people did not mean better nutrition or a better life.
The great transformation was that more people could sustain their lives on the same piece of land. Agriculture changed humanity’s demographic limits. Could greater production, then, have meant more people before it meant wealthier individuals?
More Food, a Better Life?
Hunter-gatherer communities relied on resources scattered across a wide area. Agriculture increased the quantity of food that could be obtained from the same area. Storage reduced the need to consume food as soon as it was obtained. This was an extraordinary change in human history.
As agriculture spread, diets changed. Hunter-gatherers consumed a wide variety of plants and animals. In agricultural societies, however, a diet more dependent on a few staple crops emerged.
Archaeological findings have revealed evidence of reduced stature, increased tooth decay, physiological stress, and infections in some societies associated with the transition to agriculture. The advantages agriculture offered do not mean that early farmers were healthier than hunter-gatherers.
Settled life meant people living close together. Under these conditions, waste accumulated in the same areas and water sources became contaminated. This meant the spread of infectious diseases. Close contact with domesticated animals also became a source of certain diseases.
Efforts to treat diseases predate agriculture by a considerable margin. Agriculture and, later, urbanization changed the conditions in which humanity encountered disease. Population density, human–animal contact, water and waste problems, and expanding social relations created new disease environments.
New ways of working developed with the Agricultural Revolution. Labour-intensive tasks emerged, including preparing the soil, sowing, weeding, harvesting, grinding grain, and transporting and storing produce. Animal husbandry also required continuous care.
Settled life may also have affected fertility. Carrying children can be a problem in a community constantly on the move. Greater access to food may have changed feeding practices during the early years of new generations. Moreover, younger generations provide a source of labour for agricultural households.
Demographic change cannot be explained by one or a small number of causes. Numerous factors, including sedentism, changes in dietary habits, women’s workloads, and the organization of household production, must be considered together.
Increased fertility did not mean that people had begun to live better lives. Agriculture made it possible to feed more people from the same piece of land. However, as food production increased, so did the population. Over time, the additional food provided by agriculture began to be shared among more people. Agricultural societies could feed larger populations. But this did not mean better nutrition or healthier lives.
Thomas Robert Malthus’s theory cannot serve as a lens through which to view the Neolithic period, but his concepts can help explain a basic mechanism. An increase in productive capacity does not necessarily translate into a lasting increase in per capita welfare over the long term. If the population is also growing, resources per person may change to a much more limited extent even as total production expands.
The argument in Jared Diamond’s 1987 article “The Worst Mistake in the History of the Human Race” relates to the point being explained through Malthus. Diamond challenges the idea that agriculture represented unquestionable progress for humanity. He focuses on deteriorating dietary quality, disease, harsher working conditions, and social inequality.
Diamond’s highly provocative claim is open to debate. However, it offers valuable intellectual ground by forcing us to question how the success of the Agricultural Revolution should be measured.
If the criteria are the total quantity of food that can be produced in a given region and the number of people it can sustain, the Agricultural Revolution was largely successful. If the criteria are health, dietary diversity, workload, and quality of life, a complex debate opens up.
The clearest outcome of the Agricultural Revolution in human history was population growth rather than greater prosperity. The word “success” is deliberately avoided here. This distinction is also crucial to understanding the fundamental difference between the Agricultural Revolution and the Industrial Revolution.
The Agricultural Revolution and the Growth of Humanity
It is meaningful to examine the consequences of the Agricultural Revolution through changes in the world’s population. However, population figures for prehistoric periods are uncertain. Estimates can only be made using archaeological findings, settlement sizes, assumptions about population density, and various demographic models. The following figures should therefore be read as orders of magnitude rather than precise values.
Around 10,000 BCE, when the Agricultural Revolution began, the world’s population is estimated to have been roughly 4–8 million. By around 5000 BCE, it had reached approximately 20 million. By the beginning of the Common Era, the world’s population numbered in the hundreds of millions. By 1700, it is possible to speak of approximately 600 million people.
If the estimated range of 4–8 million for 10,000 BCE is taken as roughly 6 million, the world’s population had increased approximately a hundredfold by 1700. In other words, over roughly 11,700 years, population growth reached approximately 10,000% in round numbers. This was an enormous increase. Yet, viewed from another angle, the same figure also reveals how slowly humanity’s population grew after the Agricultural Revolution.
An increase from approximately 6 million to 600 million over 11,700 years implies a compound average annual growth rate of roughly 0.039%. Although this rate appears extremely low compared with today’s population growth rates, its continuation over millennia was enough to bring the world’s population to an entirely different scale.
Agriculture made more births and higher population densities possible. However, high fertility in prehistoric and agricultural societies was accompanied by high mortality. Infant and child mortality rates were high. Epidemics, famines, wars, and poor harvests had significant effects on population change. Long-term population growth was therefore a relatively slow process.
The extensive areas used by hunter-gatherer communities generally supported relatively small populations. Agriculture made it possible to feed far more people within the same region. Greater production fed more people. But more people also meant that existing production had to be shared among a larger number of individuals.
In the modern world, economic growth is generally understood as an increase in real income per capita. The great transformation brought about by the Agricultural Revolution primarily involved total production and population increasing together.
The world’s population, approximately 600 million in 1700, has reached approximately 8.3 billion in 2026. This represents an increase of approximately 1,280% in just 326 years. In percentage terms, the increase between 10,000 BCE and 1700 was approximately 10,000%. Yet the first increase took approximately 11,700 years, while the second took just 326 years. The difference is striking.
Let us imagine that, after 1700, the world’s population continued to grow at the average annual rate of 0.039% recorded between 10,000 BCE and 1700. In other words, let us assume that the demographic acceleration following the Industrial Revolution never occurred. In this scenario, the world’s population, approximately 600 million in 1700, would have reached 682 million in 2026. Today, the world’s population is approximately 8.3 billion, roughly twelve times 682 million.
Wars, diseases, technological changes, agricultural innovations, trade, and countless other historical developments could have produced a different population trajectory. The purpose of this calculation is to emphasize the difference between the very long-term demographic growth rate following the Agricultural Revolution and the rate that emerged in the modern period.
Population was not the only thing that changed after the Industrial Revolution. Over the long term, production began to grow faster than population. A sustained rise in real income per capita became possible. In agricultural societies, a substantial share of increased production went towards meeting the needs of a growing population. With industrialization, increased production also raised the quantity of goods and services available per person. Production could grow persistently faster than population. Real income per capita could therefore also rise over the long term.
How Did Surplus Production Change Society?
The ability to produce cereals and store them for extended periods introduced a new interval between harvest and consumption. It was no longer necessary to consume all the food produced immediately. Some could be stored for later use. Storage did not begin with agriculture. We know that hunter-gatherer communities also stored food. However, the scale and importance of storage increased in agricultural societies.
At this point, the concept of “surplus production” came into play. Surplus was the portion of existing production that exceeded immediate subsistence needs. Its existence placed entirely different questions on humanity’s agenda. Who produces the goods? Who controls production? How are the goods distributed?
As agricultural societies grew, conditions emerged in which people did not have to devote all their time directly to food production. For groups specializing in different activities—such as craftspeople, builders, traders, soldiers, administrators, and religious officials—to emerge, the food they consumed had to be produced by others. There is a strong correlation between agricultural productivity and a deepening division of labour. The Agricultural Revolution laid the groundwork for the development of organization.
It would be wrong to assume that specialized occupations, classes, or the state emerged as soon as surplus production appeared. A long period separates the tenth millennium BCE, when agriculture began to emerge, from the fourth and third millennia BCE, when cities and state organizations appeared in Mesopotamia. This long interval shows that an inevitable and direct causal relationship cannot be established between agriculture and the state.
Two concepts developed by Gordon Childe help us understand this distinction. Childe called the transformation based on the domestication of plants and animals the Neolithic Revolution, and the much later emergence of large cities, specialization, political organization, and complex economic relations the Urban Revolution. The two transformations were connected. But they were not the same event.
Childe’s distinction also explains why large Neolithic settlements such as Çatalhöyük should not be placed in the same category as later Mesopotamian cities. Çatalhöyük was an extraordinarily large settlement where thousands of people could live together. However, the centralized administrative institutions, extensive occupational specialization, and political hierarchy found in Uruk, which developed in the fourth millennium BCE, indicate a very different form of social organization. The size of a settlement does not necessarily make it a city.
Surplus production is also politically important. The ability to store, measure, and collect produce at particular centres made it possible to establish control over production. The resulting surplus was more than a stock for future consumption. Over time, it also became a source of power.
The political dimension of surplus production also helps us understand the subsequent history of inequality. We certainly cannot assume that all hunter-gatherer communities were egalitarian. Nor would it be correct to think that agriculture invented inequality. However, the ability to accumulate resources through land, animal herds, and stored produce, and to transfer them between generations, created entirely new conditions under which differences in wealth could become enduring. Control over the means of production and the surplus opened the way for economic differences to become political differences.
James C. Scott’s Against the Grain examines the particular relationship early states established with cereal production. Cereals such as wheat and barley ripen at particular times and grow in fields (a visible area) and, once harvested, can be measured, divided, stored, and transported. These characteristics made grain a product that political authorities could monitor and control.
For some crops that remain underground and can be dug up as needed, it is difficult to assess their quantity from the outside or seize the entire harvest. Grain makes both the location of production and the approximate timing of the harvest visible. In Scott’s terms, grain was a “legible” form of production for the early state.
At this point, taxation enters the picture. The ability to estimate the quantity of produce made it easier to collect a portion as tax in kind or tribute and gather it in central storehouses. Surplus produce could feed soldiers, administrators, priests, craftspeople, and construction workers.
Taxation did not begin simply because agriculture began in the tenth millennium BCE. It must be emphasized that thousands of years separated the first agricultural communities from state structures capable of collecting taxes. Agriculture and storable produce created one of the important material conditions on which states could arise under later historical circumstances.
Surplus production can allow some members of a society to withdraw from direct food production and specialize in other activities. This can contribute to the development of crafts, trade, administration, and specialized fields of knowledge. The same surplus can also become a means for the groups controlling it to establish economic and political power over others.
The Agricultural Revolution did more than change people’s relationship with nature. It also changed the material foundations of their relationships with one another.
Land ceased to be merely an area on which people lived. It became a productive resource. Produce ceased to be merely food for consumption. It became storable wealth. Surplus produce ceased to be merely a guarantee of future sustenance. It became the capacity to organize other people’s labour and lives.
On the foundations of this transformation, villages grew, occupations became differentiated, inequalities became entrenched, and, much later, cities and states emerged. This is precisely where the political history of the Agricultural Revolution began.
Agriculture’s Repeated Transformations
The Agricultural Revolution began around 10,000 BCE, but agriculture continued to change and evolve. Humans developed new methods to cultivate more land, obtain more produce from the same land, control water, and overcome the limits of human labour.
One of the major changes in agricultural history was the more systematic use of human and animal power in production. The plough made it possible to cultivate land on a larger scale than with hand tools.
Control over water changed the scale of agricultural production. Particularly in regions such as southern Mesopotamia, where rainfall was insufficient for agriculture, irrigation systems channelled river water into agricultural production. Digging and maintaining canals required collective labour and organization. Technological development in agriculture also changed how production was organized.
The spread of metal tools created further possibilities for cultivating the soil. Iron agricultural tools made it possible to cultivate certain soils more effectively.
Carrying capacity refers to the population that a particular environment can sustain over the long term under existing conditions of natural resources and production technology. Each innovation increased the population that a given region could support through agricultural production. More land could be cultivated with the same amount of labour, more produce could be obtained from a given area, or previously unproductive land could be brought into use. Nevertheless, the basic mechanism described in earlier sections largely persisted. Productivity gains increased total production. Over the long term, a growing population absorbed a substantial share of these gains. Technological progress occurred. However, a continuous and lasting rise in living standards per person did not emerge.
The transformation of agriculture, particularly in England, gave rise to the British Agricultural Revolution between the seventeenth and nineteenth centuries. This revolution brought production into closer integration with the market and contributed to rising agricultural productivity.
Jethro Tull developed the seed drill in the early eighteenth century. Charles “Turnip” Townshend’s name became closely associated with the Norfolk four-course crop rotation system, which included turnips. Robert Bakewell became one of the leading figures in the systematic application of selective breeding methods to sheep and cattle.
Inventions became integrated with changes in land use, the enclosure movement—which brought common agricultural land under private use and ownership—the expansion of markets, regional specialization, changes in the relationship between animal husbandry and crop cultivation, and long-term productivity gains. Agricultural transformation thus formed part of an economic and institutional change too broad to be explained by technologies developed by a handful of inventors.
Agriculture’s thousands-of-years-long history eventually became intertwined with the Industrial Revolution. A more productive agricultural sector made it easier to feed the non-agricultural population. The gradual decline in the share of the total population working in agriculture allowed more people to move into industry and services. Meeting the food needs of growing cities depended on the development of agricultural production and distribution capacity.
Beyond a certain point, the Agricultural Revolution and the Industrial Revolution should be understood as two intertwined historical transformations. The Neolithic transformation had turned humanity into a food producer. Thousands of years of agricultural innovation expanded the capacity of this production system. In the early modern period, the relationships between agricultural productivity, market development, and urbanization created some of the conditions under which industrialization could emerge. Over time, this relationship also began to work in the opposite direction. The Industrial Revolution began to transform agriculture.
Railways enabled agricultural products to reach distant markets. Industry produced advanced agricultural machinery. Chemistry transformed fertilizer production. Fossil fuels overcame the energy limits imposed by human and animal muscle power. In the nineteenth and twentieth centuries, combine harvesters, tractors, and other machines fundamentally changed the structure of labour in agricultural production.
The development of the Haber–Bosch process in the early twentieth century marked one of history’s most important turning points. The ability to convert atmospheric nitrogen into industrially usable compounds made the production of synthetic nitrogen fertilizers possible. Agricultural production was no longer dependent solely on the soil’s natural nitrogen cycle, animal manure, and limited organic resources. Industry had begun to expand one of agriculture’s biological limits through chemical means.
From the mid-twentieth century onwards, in the process known as the Green Revolution, the combined use of high-yielding wheat and rice varieties, irrigation, synthetic fertilizers, pesticides, and mechanization greatly increased crop yields, particularly in parts of Asia and Latin America. These developments made it possible to feed a much larger global population. However, intensive water and energy use, dependence on chemical inputs, pressures on the soil, and environmental costs created new problems.
This long transformation continues today through genetics, satellite systems, sensors, precision agriculture, drones, and artificial intelligence applications.
The First Great Transformation of Production in Human History
The Agricultural Revolution was a multidimensional transformation that changed where people lived, how they worked, what they ate, how many children they could have, which diseases they encountered, and the economic and political relationships they established with one another.
In some early agricultural societies, dietary diversity declined, the burden of disease increased, and strenuous physical labour became a major part of daily life. Over the long term, a substantial share of the increase in total production could be absorbed by a growing population. As agricultural societies produced more and more, living standards per person did not rise continuously or on a comparable scale.
The Agricultural Revolution had changed humanity’s carrying capacity. With the Industrial Revolution, the rate at which this capacity expanded reached an entirely different level.
After the Industrial Revolution, population growth far exceeded even the effects of the Agricultural Revolution. However, the Industrial Revolution also began to bring sustained increases in real output per capita over the long term. The demographic mechanism that had absorbed a substantial share of productivity gains in agricultural societies was thus overcome. With the Industrial Revolution, humanity added the ability to produce far more goods and services per person to its ability to sustain more people.
The Agricultural Revolution did not create modern economic growth. However, it created the much older world of production on which modern economic growth would be built.
Human history shows that the impact of a new production technology cannot be measured solely by how much additional output it generates. Technology also changes who produces what, who controls which resources, how people work, and how the gains from production are distributed within society.
With the Agricultural Revolution, surplus production enabled specialization and could become one of the means through which economic and political power became concentrated in particular hands. During the Industrial Revolution, machinery, capital, and energy sources played a central role in the organization of production. In both transformations, the great expansion of productive capacity occurred alongside the reorganization of social relations.
When we look at the Agricultural and Industrial Revolutions, we know their long-term consequences. By contrast, we are living through the artificial intelligence transformation. It would be wrong to draw a direct analogy between the Agricultural and Industrial Revolutions and today’s artificial intelligence transformation. However, it is meaningful to ask questions similar to those we ask about the past.
The historical significance of today’s technological transformations will not emerge solely from how much productivity they generate. How that productivity translates into human lives will be the fundamental determinant of their historical significance. Just as it was with the Agricultural and Industrial Revolutions.
