Agricultural revolution refers to major changes in farming and food production. These changes happened at different times in history and in different regions. They allowed people to produce more food.

The first major agricultural revolution began around 10,000 BCE when people started farming instead of hunting and gathering. Later, in the 1700s, new methods in Europe such as crop rotation and improved tools increased production. Farmers also began breeding animals more carefully.

These changes are studied through tools, records, and farming systems. Agricultural revolutions are linked to growing populations and expanding settlements.
