Johann Heinrich von Thünen (Canarienhausen today Wangerland, Lower Saxony, June 24, 1783 - Tellow, Mecklenburg, September 22, 1850), was a German economist, well known for his theory of location or location, on rural geography -urban.
Von Thünen's localization theory is a general hypothesis about the distribution of agricultural land uses.
The theory of the location of the ground has its origin in the works that made in Germany in 1820 Johann Heinrich von Thünen, The isolated state. His model studies the differences in income with respect to the market, which becomes a paradigm for all subsequent theories. Not in vain uses the deductive method in their reasoning, which is a commitment to the scientific method, as explained by David Harvey. The central idea is that income varies with distance from the market, in an isotropic and isolated space. This type of income is called location rent or location rent. Von Thünen acknowledged that men try to solve their economic needs in the immediate environment, reducing their movements to the minimum.
Von Thünen wondered why the lots of land, with the same characteristics, had different uses. He concluded that it was explained by the distance to the market.
