There were eight Neolithic crops: emmer wheat, einkorn wheat, peas, lentils, bitter vetch, hulled barley, chickpeas, and flax. The Neolithic era ended with the development of metal tools. Evidence suggests that irrigation first appeared in Egypt and Mesopotamia in the fourth millennium B.
Floods caused by the yearly inundation of the Nile would have had disastrous effects for ancient farmers, washing away dikes and swamping fields. Conversely, when the waters were low, the land dried up, killing crops. The oldest method of irrigation made use of man-made underground streams, called qanats , and is still being used in parts of the Middle East. Various groups of people began digging and repairing older, more primitive canal networks to help regulate the flow of rivers, such as the Nile River in Egypt.
The canal networks eventually developed into sophisticated irrigation systems. During the Bronze Age and the eras that followed, civilizations all over the world gradually invented or acquired advanced metalworking techniques, creating ever-stronger farming implements. Humans continued domesticating animals and plants to serve as food sources or sources of other useful products. During the Middle Ages, European farmers began using complex irrigation systems such as dams, reservoirs, and water-raising machines.
They also developed a three-field system of crop rotation and the moldboard plow. When you reach out to them, you will need the page title, URL, and the date you accessed the resource. If a media asset is downloadable, a download button appears in the corner of the media viewer.

Agricultural communities developed approximately 10, years ago when humans began to domesticate plants and animals. By establishing domesticity, families and larger groups were able to build communities and transition from a nomadic hunter-gatherer lifestyle dependent on foraging and hunting for survival.
Select from these resources to teach your students about agricultural communities. Hunter-gatherer cultures forage or hunt food from their environment. Often nomadic, this was the only way of life for humans until about 12, years ago when archaeologic studies show evidence of the emergence of agriculture. Human lifestyles began to change as groups formed permanent settlements and tended crops.
There are still a few hunter-gatherer peoples today. Explore the lifestyle of hunter-gatherers in your classroom with these resources. Agriculture is the art and science of cultivating the soil, growing crops and raising livestock. Domestication is the process of adapting wild plants and animals for human use.

The San are among the first people to have lived in southern Africa, and are one of the few societies that still follow a hunter-gatherer diet. To sustain their lifestyle, San typically spend 12 to 19 hours per week gathering food from the wild—what many might consider a life of leisure. When one San person was asked why he hadn't adopted farming, he replied, "Why should we, when there are so many mongongo nuts in the world?
Paleoanthropologists have estimated that the earliest fossil evidence of Homo sapiens— anatomically modern humans—is roughly , years old. From as early as 11, BCE, people began a gradual transition away from a hunter-gatherer lifestyle toward cultivating crops and raising animals for food.
The shift to agriculture is believed to have occurred independently in several parts of the world, including northern China, Central America, and the Fertile Crescent, a region in the Middle East that cradled some of the earliest civilizations. Why did people give up hunting and gathering for farming? There are many plausible reasons, all of which likely played some role at different times and across different parts of the world:.
An ox-drawn plow prepares a rice paddy field in Vietnam. The plow and the various improvements upon its design were innovations that transformed human history, allowing farmers to cultivate land with a fraction of the labor they once used. Pulled by animals or tractors, plows are used to turn over the top layer of soil, helping destroy weeds, bury residues from previous crops, bring nutrients and moisture to the surface, and loosen soil before planting.

Although it brought tremendous gains in short-term productivity, it has also been a major contributor to soil erosion. The loss of fertile topsoil has played a role in the decline of numerous civilizations. Farming probably involved more work than hunting and gathering, but it is thought to have provided 10 to times more calories per acre. Small settlements grew into towns, and towns grew into cities. Agriculture produced enough food that people became free to pursue interests other than worrying about what they were going to eat that day.
Hunting, gathering, and farming, however, can complement one another in ways that provide people with a more varied and abundant food supply. People still harvest aquatic plants and animals from the sea, for example, and even urban dwellers might find edible berries, greens, and mushrooms in their local park.
Depleted farmland and a changing climate set the stage for periodic famines throughout much of Europe from to Image attributed to Michael Wolgemut, Public domain. Agriculture may have made civilizations possible, but it has never been a safeguard against their collapse. Throughout history, increases in agricultural productivity competed against population growth, resource degradation, droughts, changing climates, and other forces that periodically crippled food supplies, with the poor bearing the brunt of famine.
Like many of their modern counterparts, early farmers often worked land in ways that depleted its fertility. Technological innovations like irrigation circa BCE and the plow circa BCE brought enormous gains in productivity, but when used irresponsibly they degraded soil—the very foundation that makes agriculture possible.
