Von Th√ľnen, Agricultural location model
Definition
The Von Thunen model of agricultural land use was created by farmer and amateur economist J.H. Von Thunen (1783-1850) in 1826 (but it wasn't translated into English until 1966). Von Thunen's model was created before industrialization and is based on the following limiting assumptions:
The city is located centrally within an "Isolated State" which is self sufficient and has no external influences.
The Isolated State is surrounded by an unoccupied wilderness.
The land of the State is completely flat and has no rivers or mountains to interrupt the terrain.
The soil quality and climate are consistent throughout the State.
Farmers in the Isolated State transport their own goods to market via oxcart, across land, directly to the central city. Therefore, there are no roads.
Farmers act to maximize profits.
