Johann Heinrich von Thünen´s () model of agricultural land from the first half of the 19th century is considered the first ever location model. PDF | On Dec 1, , M. E. O’Kelly and others published Agricultural location theory: Von Thünen’s contribution to economic geography. It is generally acknowledged that the roots of agricultural location theory can be von Thunen’s type of rent ‘location rent’ (see Chisholm, , or Ponsard.

There was one year of rye, one of barley, one of oats, three of pastures and one of fallow. Animals can be raised far from the city because they are self-transporting. Cattle beef and range ; horses range ; and sheep range ; salt, smoked, refrigerated, and canned meats; bones; tallow and hides. The main task is to set up the investigation by cataloging physical-environmental and economic-empirical irregularities in order to derive an appropriate map of the expected real-world spatial pattern.

The model was developed in thnen isolated state and did not take into consideration differences in sites local physical conditions. The myriad of vegetable, dairy, mixed crop and livestock, wheat, and cattle-ranch land users eagerly submit their rent-bids to the landowners. The more distant belts would specialise in products which were less in weight and volume but fetched higher price in the market as they could afford to bear relatively higher transportation costs.

Finally, von Thunen incorporated two examples of modifying factors in his classic model. Moreover, inner-ring farming is distinguished by the production of goods that do not easily withstand long-distance transportation.

The greatest importance hheory the theory lies in this fact that it has given a new direction of thinking, resulting into the modified way of its application.

Among his general conclusions were that land values decline with increasing distance from the market centre; and that land values and land uses change as the various costs of production, transportation, and prices of agricultural commodities change.

Second, he introduced a second and smaller market, around which he postulated that a series of separate zones would be created.


Each belt, according to von Thunen, specialises in the production of those agricultural commodities to which it was best suited Figure By combining the American and European patterns and proceeding to a yet greater level of spatial aggregation, one can even perceive in Figure But this model is still considered to be significant in many ways.

Von Thunen himself relaxed certain assumptions of his model. This was a agricuptural system whereby one-third of the land was used for field crops, another one-third for pastures and the rest was left fallow.

The von Thunen model is also static and deterministic. Von Thunen himself has admitted that with the change in location of transportation or market centre the pattern of land use will also change.

The third zone consists of extensive fields crops such as grain. It corresponds to the maximum amount a farmer could pay for using the land, without making losses. For every farmer, regardless of the crop or type of livestock raised, the answer is indisputable: By using this site, you agree to the Terms of Use and Privacy Policy. Once a least-transport-cost location had been established within the triangle, Weber attempted to determine a cheap-labour alternate location.

The economic rent considering three crops horticulture, forest products and intensive arable cereals has been plotted in Figure We begin again by relaxing the normative assumptions of the isolated state model, but this time with the realisation that empirical irregularities will be complex in the sophisticated economic space of the present-day continental United States. A distance-decay relationship and an inverted cone is revealed, with land values declining as distance from the central peak increases.

For example, the aggregate locational rent for a 50 acre vegetable farm in the inner production ring can be roughly equivalent to a 1, acre ranch in the most peripheral zone. At the same time evaluation of all potential locations is released, which leads to a zoning of the possible offers.

The extent to which these relaxations affect the simple von Thunen thwory will depend on how they affect the simple conceptual framework put forward earlier. The effect can clearly be seen of a navigable river where transport was speedier and cost only one-tenth as much as on land, together with the effect of smaller city acting as a competing market centre.

The influence of availability of information also substantially modifies the concentric zone of agricultural land use. Producers on farmland with better access to the central market must use that land intensively to produce high enough revenues to afford to be located there. Agricultural land use patterns that are evident surrounding market centres are thought to be historic remnants of a bygone era, or the result of administrative institutions whose existence brings about a usage to the historic patterns of land use.

The curve sets the maximum amount of rent any land use type will yield for a specific location. Therefore, the truest measure of economic distance in the Thunian model — the absolute mileage beyond which farming was simply too far from the market and could no longer yield locational rent — is in terms of a hour time — agricutlural.

First he plotted the variation of transportation costs against the least-transport-cost location.
