What were the new agricultural practices?

The Agricultural Revolution, the unprecedented increase in agricultural production in Britain between the mid-17th and late 19th centuries, was linked to such new agricultural practices as crop rotation, selective breeding, and a more productive use of arable land.

Why is rotation important for crops?

Crop rotation is the practice of growing a series of dissimilar types of crops in the same area in sequential seasons to help restore plant nutrients and mitigate the build-up of pathogens and pests that often occurs when one plant species is continuously cropped . Rotation can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants. The Norfolk System, as it is now known, rotates crops so that different crops are planted with the result that different kinds and quantities of nutrients are taken from the soil as the plants grow. An important feature of the Norfolk four-field system was that it used labor at times when demand was not at peak levels. Planting cover crops such as turnips and clover was not permitted under the common field system because they interfered with access to the fields and other people’s livestock could graze the turnips.

What crops were planted in the Middle Ages?

Following a two-field crop rotation system common in the Middle Ages and a three-year three field crop rotation routine employed later, the regular planting of legumes such as peas and beans in the fields that were previously fallow became central and slowly restored the fertility of some croplands.

How did legumes help plants grow?

The planting of legumes helped to increase plant growth in the empty field due to the bacteria on legume roots’ ability to fix nitrogen from the air into the soil in a form that plants could use . Other crops that were occasionally grown were flax and members of the mustard family.

Why is crop rotation important?

It helps in reducing soil erosion and increases soil fertility and crop yield.

How did enclosures increase the value of land?

Enclosure could be accomplished by buying the ground rights and all common rights to accomplish exclusive rights of use , which increased the value of the land. The other method was by passing laws causing or forcing enclosure, such as parliamentary enclosure. The latter process of enclosure was sometimes accompanied by force, resistance, and bloodshed, and remains among the most controversial areas of agricultural and economic history in England.

What was the third agricultural revolution?

The Third Agricultural Revolution involves genetic engineering of products as well as the increased use of fertilizers for crops and antibiotics in animal products, 3) Von Thunnen’s Model focuses on transportation. The distance and weight of crops as well as their distance to market affect which ones are grown.

What was the agricultural revolution?

The agricultural revolution is the name given to a number of cultural transformations that initially allowed humans to change from a hunting and gathering subsistence to one of agriculture and animal domestications. Today, more than 80% of human worldwide diet is produced from less than a dozen crop species many of which were domesticated many years ago. Scientists study ancient remains, bone artifacts, and DNA to explore the past and present impact of plant and animal domestication and to make sense of the motivations behind early cultivation techniques. Archeological evidence illustrates that starting in the Holocene epoch approximately 12 thousand years ago (kya), the domestication of plants and animals developed in separate global locations most likely triggered by climate change and local population increases. This transition from hunting and gathering to agriculture occurred very slowly as humans selected crops for cultivation, animals for domestication, then continued to select plants and animals for desirable traits. The development of agriculture marks a major turning point in human history and evolution. In several independent domestication centers, cultivation of plants and animals flourished according to the particular environmental conditions of the region, whereas human migration and trade propelled the global spread of agriculture. This change in subsistence provided surplus plant food that accumulated during the summer and fall for storage and winter consumption, as well as domesticated animals that could be used for meat and dairy products throughout the year. Because these new survival strategies no longer required relocation and migration in search of food, humans were able to establish homesteads, towns, and communities, which, in turn, caused rapid increases in population densities and lead to the emergence of civilizations. This dependence on plant and animal domestication entailed a number of other environmental adaptations including deforestation, irrigation, and the allocation of land for specific crop cultivation. It also triggered various other innovations including new tool technologies, commerce, architecture, an intensified division of labor, defined socioeconomic roles, property ownership, and tiered political systems. This shift in subsistence mode provided a relatively safer existence and in general more leisure time for analytical and creative pursuits resulting in complex language development, and the accelerated evolution of art, religion, and science. However, increases in population density also correlated with the increased prevalence of diseases, interpersonal conflicts, and extreme social stratification. The rise of agriculture and the influence of genetics and culture (gene–culture coevolution) continue to affect modern humans through alterations in nutrition, predisposition to obesity, and exposure to new diseases. This chapter will cover the various regions that adopted early agricultural practices and look at the long-term positive and negative effects of agriculture on society.

How did the agricultural revolution affect the human population?

The agricultural revolution in developing countries has produced large resident human populations with the potential for direct person-to-person spread of infection and greater environmental contamination by feces.

How does agriculture affect humans?

What are the inputs used in agriculture?

In general, agricultural inputs are chemical and biological materials used in crop production.

How did the Neolithic population change?

The Neolithic or agricultural revolution resulted in a demographic transition and major increases in population (Table 6.1) and population density ( Table 6.3 ). The population of hunter–gatherers rose at a very low rate constrained by the carrying capacity of the land (see Chapter 4, Fig. 4.1 ). The increase in Paleolithic global populations parallels the increase in range as humans migrated from Africa to Asia, Europe, the Americas, and Australia. The increase in the growth rate of human populations increased by as much 60-fold with the Neolithic Revolution ( Table 6.1 ). “Population, when unchecked, goes on doubling itself every twenty-five years or increases in a geometrical ratio” ( Malthus, 1798 ). This is seen in the USA with the population rising from 2.5 million in 1776 to 5.3 million in 1800 to 11.1 million to 1825 and 23.2 million in 1850 ( US Census, in press ); the population growth being unchecked as more land came into cultivation.

When did domestication begin?

Archeological evidence illustrates that starting in the Holocene epoch approximately 12 thousand years ago (kya), the domestication of plants and animals developed in separate global locations most likely triggered by climate change and local population increases.

What were the main developments in agriculture during the agricultural revolution?

In China, humans used flood and fire control to create rice paddies beginning around 6,000 B .C. They domesticated water buffalos and yaks to eat their meat and milk and their hair and hide to make clothing. In Mexico, humans selectively bred a wild plant called teosinte to create maize or corn. The earliest known corn cob dates from 3,500 B.C. These same humans grew squash, which would become a staple food throughout the Americas. At the same time in the Andes Mountains of South America, humans grew potatoes.

Why was the Third Agricultural Revolution called the Green Revolution?

This time period received its name because of the emphasis on creating crops that yielded the most produce. Improvement in fertilizers and irrigation allowed crops to grow in climates previously too dry. Agricultural scientists like American researcher Norman Borlaug bred plants resistant to disease, produced more grain, and responded well to fertilizers. Industrial farms raised a single strain of highly productive plant. While these homogeneous crops increased yield, they were less disease-resistant and elevated the need for pesticides.

Why did the first agricultural revolution occur?

Because this revolution began about 14,000 years ago at the end of the last Ice Age, experts theorize the warmer climate drove early humans to plant crops and build homes. At the same time, humans developed aspects of culture like religion and art. Archeologists have discovered cave art and figurines from this period. These discoveries demonstrate how humans had developed greater intellectual capabilities than their ancestors. Additionally, these new beliefs may have encouraged humans to settle in a permanent community with like-minded people.

What was the second agricultural revolution?

The Second Agricultural Revolution, or the British Agricultural Revolution, began during the 18th century. Major changes to farming techniques, which included livestock breeding, crop rotation, and mechanical farm equipment, decreased the number of workers needed on farms.

How did agriculture change the world?

The innovations in agriculture radically changed how humans produced food. Crop rotation and livestock breeding resulted in higher yields, while new mechanical equipment required fewer workers. Because their work was no longer needed, people traveled to cities to find work. Some people were desperate for employment in factories or other city jobs. Their small family farms could not compete with larger, industrial farms, or modern farming equipment had rendered their labor obsolete. In contrast, the children of successful farmers could now leave their families to look for other employment without worrying about who would work on the farm. The surplus produce from industrial farms could be sold to city dwellers, which in turn allowed more people to have occupations other than farming.

How did the agricultural revolution affect people?

The agricultural revolutions affected how people worked and got their food. The first caused people to grow crops and raise animals for food. The second caused people to move into cities and work in factories . The third led to an increase in human population.

Where did the agrarians live?

Abu Hureyra in modern Syria is another site showing an agrarian lifestyle. Humans lived in this village between 11,500 to 7,000 B.C. The residents of this village were originally hunters. However, archeologists have discovered tools used for grinding grain. This evidence suggests the people at Abu Hureyra had become farmers.
