First agricultural revolution (circa 10,000 BC), the prehistoric transition from hunting and gathering to settled agriculture. plant crops rather than gathering them. started using slash and burn so the soil could have lots of nutrients. First Agricultural revolution (11,000 b.c.)- it's when people started to plant crops instead of gathering crops. It's also known as the Neolithic revolution. It happened around 11,000 years ago. People started to plant crops instead of scavenging for food, such as planting wheat. People used the method slash and burn so the soil could have a lot of nutrients.

Second Agricultural Revolution (1930s–1960s), an increase in agricultural production, especially in the developing world. happened in western europe Second Agricultural revolution- it happened in Western Europe in about the 1700s. It introduced horse collars, seed drills and tractors. It changed farming by producing and planting crops faster and more efficient. It also introduced a system called the crop rotation, it's when farmers choose one crop to grow one year and another year choose a different crop to grow the whole year. New crops were grown such as corn and potatoes for livestock. Von Thunen makes a model about spatial character of economic activity.

The Third Agricultural Revolution (also called the Green Revolution):

The Green Revolution was a period in time when new agricultural practices were created to help farmers all over the world. It was an international effort that was planned to eliminate hunger by improving crop performances. This plan provided new practices that allowed farmers to produce more of the same product within the same amount of land. This meant that the farmers could get more out of their land than they used to. This rapid diffusion of more productive agriculture techniques occurred throughout the 1970s and the 1980s. The plan had two main practices: the introduction of newer higher-yield seeds and the expanded use of fertilizers. This would lead to the increase of the agricultural productivity at a global scale, which increased faster than population growth. The Green Revolution answered questions from experts about massive global famine.

Summary: the agricultural revolutions all lead to huge increases in the amount of food farmers can produce, and the quality increases each time too.
