In common law systems, land tenure, from the French verb "tenir" means "to hold", is the legal regime in which land "owned" by an individual is possessed by someone else who is said to "hold" the land, based on an agreement between both individuals. It determines who can use land, for how long and under what conditions. Tenure may be based both on official laws and policies, and on informal local customs. In other words, land tenure implies a system according to which land is held by an individual or the actual tiller of the land but this person does not have legal ownership. It determines the holder's rights and responsibilities in connection with their holding. The sovereign monarch, known in England as the Crown, held land in its own right. All land holders are either its tenants or sub-tenants. Tenure signifies a legal relationship between tenant and lord, arranging the duties and rights of tenant and lord in relationship to the land. Over history, many different forms of land tenure, i.e., ways of holding land, have been established.

A farmer 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 farmland or might work as a laborer on land owned by others. In most developed economies, a "farmer" is usually a farm owner (landowner), while employees of the farm are known as farm workers. However, in other older definitions a farmer was a person who promotes or improves the growth of plants, land, or crops or raises animals by labor and attention.
