A farmer (also called an agriculturer) is a person engaged in agriculture, raising living organisms for food or raw materials. The term usually applies to people who do some combination of raising field crops, orchards, vineyards, poultry, or other livestock. A farmer might own the farmed land or might work as a labourer on land owned by others, but in advanced economies, a farmer is usually a farm owner, while employees of the farm are farm workers, farmhands, etc.
Farming has been dated back as far as the Neolithic era. By the Bronze Age, the Sumerians had an agricluture specialized labour force by 5,000-4,000 B.C., and heavily depended on irrigation to grow crops. They relied on three person teams when harvesting in the spring.The Ancient Egypt farmers farmed and relied and irrigated their water from the Nile.
Animal husbandry, the practice of rearing animals specifically for farming purposes, has existed for thousands of years. Dogs were domesticated in East Asia about 15,000 years ago. Goats and sheep were domesticated around 8000 BCE in Asia. Swine or pigs were domesticated by 7000 BCE in the Middle East and China. The earliest evidence of horse domestication dates to around 4000 BCE.
More distinct terms are commonly used to denote farmers who raise specific domesticated animals. For example, those who raise grazing livestock, such as cattle, sheep, goats, and horses, are known as ranchers (U.S.), graziers (Australia & U.K.), or simply stockmen. Sheep, goat, and cattle farmers might also be referred to respectively as shepherds, goatherds, and cowherds. The term dairy farmer is applied to those engaged primarily in milk production, whether from cattle, goats, sheep, or other milk producing animals. A poultry farmer is one who concentrates on raising chickens, turkeys, ducks, or geese, for either meat, egg, or feather production, or commonly, all three. A person who raises a variety of vegetables for market may be called a truck farmer or market gardener. Dirt farmer is an American colloquial term for a practical farmer, or one who farms his own land.
In developed nations, a farmer (as a profession) is usually defined as someone with an ownership interest in crops or livestock, and who provides land or management in their production. Those who provide only labor are most often called farmhands. Alternatively, growers who manage farmland for an absentee landowner, sharing the harvest (or its profits) are known as sharecroppers or sharefarmers. In the context of agribusiness, a farmer is defined broadly, and thus many individuals not necessarily engaged in full-time farming can nonetheless legally qualify under agricultural policy for various subsidies, incentives, and tax deductions.
