After covering the Weber’s theory of industrial location, I have covered a very important topic of Human Geography, Von Thunen theory of agricultural location. For the exam perspective, this topic is very important for geography optional in bpsc and upsc.Thank you for reading this post, don't forget to subscribe!
The agricultural location theory is a normative economic model which was first presented in 1826 in a book called Der Isolierate Stat. This theory is based on the concept of Economic Rent which is prevalent in farm market distance relationship. The agricultural location theory is one of the earliest attempts to explain the pattern of land use in economic terms which was proposed by Von Thunen.
Von Thunen theory of agricultural location predominantly concerned with the agriculture, types of agriculture and prosperity of an urban market. He devised this theory by calculating the relevant data of last five years of Mecklenburg. Above all, the main aim of Von Thunen’s model on agricultural location was to show how and why agricultural land use varies with the distance from the market.
Based on the value of production of varied agricultural produce, yields, cost of transportation and market prices, he demarcated six concentric zones with different agricultural production.
Economic rent is defined as the net income accruing to an area of land above the net income of land at the economic margin of production. The economic rent of a crop increases if the location of agricultural land is near the market due to less transportation cost. Von Thunen’s concept of economic rent is also known as locational rent since the economic rent is estimated by the location of agricultural land.
Due to the rise in transportation cost, intensive cultivation is most suitable near the city centre. Therefore, the intensity of production of a particular crop declines with distance from the market.
According to crop theory, there will be a variation in the land use with distance and the factors responsible for the variation in the land use pattern are market price of a particular crop, transportation cost, production cost and yield per unit of land. The crop theory of Von Thunen can be understood by taking the following two cases.
When two crops P and Q have the same production cost and yield but having different transport cost and market price. If P is costlier to transport and has a higher market price then crop P will be grown closer to the market than Q. Due to higher transportation cost of crop P, the location rent of P decreases more rapidly.
When two crops X and Y have the same production and transportation cost (per tonne/km) but different market price and yield per unit of land. If X has a higher yield and lower market price than Y, it will be grown closer to the market than Y.
The zone-1 would be dedicated to cash cropping. Due to deficiency of food preservation facilities, primitive modes of transportation and highly perish nature of products, market gardening and milk production were most suitable in this zone.
The second zone was marked by the production of firewood. Due to heavy bulkiness and primitive transportation modes, wood was comparatively costly to be shipped. It was also used as a fuel and building material. However, the outer limit of this zone was marked by wood which was highly in demand in the market.
Unlike zone-2, the zone-3 was marked by food grains. Rye was the most important market product of this zone, having no fallow land. The cropping intensity of this zone was highest as compared to zone-4 and zone-5. Most importantly, grains could be stored, easy to transport and last longer than milk products. Also, the agricultural land would be cheaper farther away from the market.
This zone was marked by 14% of fallow land, having less crop intensity as compared to zone-3. The farmers of this zone usually practised seven years crop rotation with one year each rotation of rye, barley and oats, three-year rotation of pastures and one year as fallow land.
Like zone-2, this zone was marked by extensive cultivation having 33% of land as fallow. The farmers of this zone practised three-field system, having 1/3rd of land as crop field, 1/3rd as pastures and rest left for fallow land.
The market products of this zone would be of two types namely, livestock and by-products of milk like cheese, butter, etc. which would not highly perishable. Also, the reduction in the volume of these by-products made them cost-effective in terms of transportation.
Despite the classical model of Von Thunen, he also incorporated other factors which directly impact the demarcation of agricultural location. The following are the modification introduced in the classical model of Von Thunen.
