This presentation is based on a agricultural land use model around the city. This is the theory of urban Geography it describe the agricultural pattern and how should the agricultural activities perform around the city. basically this Model was put forwarded before industrialization and when there was no roads networks and this Model is not applicable in real word but is gives great ideas for developing new towns and cities.

5. BASIC TERMS
•Agriculture: the science or practice of farming, including cultivation of the
soil for the growing of crops and the rearing of animals to provide food, wool,
and other products.
•Land use : the use of land for particular propose (agriculture, settlements,
forest )
•Intensive forming :Intensive farming or intensive agriculture is a kind of
agriculture where a lot of capital and labor are used to increase the yield that
can be obtained per area. The use of large amounts of pesticides for crops and
of medication for animal stocks is common.
•Extensive forming :Extensive farming or extensive agriculture (as opposed to
intensive farming) is an agricultural production system that uses small inputs of labor,
fertilizers, and capital, relative to the land area being farmed.
•Isotropic: Same
•Bid rent: how much someone is willing to pay for a particular piece of land

6. INTRODUCTION
The agriculture land use model developed by JOHANN
HEINRICH VON THEUNAN (1783-1850) IN EARLY 1800’S
(19TH CENTURY).but it wasn't translated into English until 1966.
He was a German skilled farmer having knowledge about economics.
His model is also know as ‘concentric rings theory of agriculture
land use’ .
The model have 4 rings which developed around the central city.
◦ Each ring shows a different type of agriculture land use.
◦ Von Thunen’s model was created before industrialization,
highways, railroads, factories, etc.

7. CON…
According to his model the relative cost of transport different
agriculture commodities to the center market determined the
agriculture land use around a city .
The most productive activities will closest to the center
market and the activities not productive enough will located
away from center city.

8. ASSUMPTION
 The land must be an isotropic. With no river , mountain etc.
The isolated state is surrounded by an unoccupied wilderness.
The soil quality and climate are consistent throughout the state.
The transport coast is proposional to distance.
All the farmer have equal access of transport.
All the farmers are economically rational .
All farmers have equal information regarding market demands,
coast of production and all attempt to maximize profits.

9. MODEL

11. EXPLANATION
1) There are four rings of agricultural activity surrounding the city.
Dairying and intensive farming occur in the ring closest to the city. The
related products (vegetables, fruit, milk and other dairy products) have
the highest profits, but also the highest transportation costs because
they are vulnerable and perishable.
2) Timber and firewood will be produced for fuel and building
materials in the second zone. Before industrialization (and coal
power), wood was a very important fuel for heating and cooking.
Wood is very heavy and therefore difficult and costly to transport.

12. CON…
3) The third zone consists of extensive field crops such as grain for
bread. Since grain lasts longer than dairy products and is much lighter
than wood transport costs are considered to be lower, allowing a
location further from the city.
4) Ranching is located in the final ring surrounding the central city.
Animals can be raised far from the city because they are self-
transporting and thus have low transport costs. Beyond the fourth ring
lies the unoccupied wilderness, which is too great a distance from the
central city for any type of agricultural product.

13. BUT IT ALWAYS DOESN,T LOOK SAME

14. BID RENT CURVE (economic rent)
 As distance from
city center
increases, cost of
land goes down

15. CON..
The model compares the relationships between production cost, the market
price and the transport cost of an agricultural commodity and is expressed as
follows: R = Y(p-c) - Yfm
R = Rent per unit of land.
Y = Yield per unit of land.
p = market price per unit of yield.
c = Average production costs per unit of yield.
m = Distance from market (in kilometers or miles).
f = Freight rate per unit of yield and unit of distance.
All agricultural land uses are maximizing their productivity (rent), which in this
case is dependent upon their location from the market (Central City). The role of
farmer is to maximize his profit which is simply the market price minus the
transport and production costs. The most productive activities (gardening or milk
production) or activities having high transport costs (firewood) locate nearby the
market.

16. CRITICISM ON MODEL
 differential transportation costs. Example: boats are the cheapest. mode
of transportation.
 variations in topography.
 soil fertility.
 changes in demand or price of the commodity.
The invention of refrigeration has largely diminished the importance of
the perishability factor.
Not only physical but social, political and cultural factor also effect
agriculture location.

17. CONCLUSION
Even though the Von Thunen model was created in a time
before factories, highways, and even railroads, it is still an
important model in geography. The Von Thunen model is an
excellent illustration of the balance between land cost and
transportation costs. As one gets closer to a city, the price of
land increases. The farmers of the Isolated State balance the
cost of transportation, land, and profit and produce the most
cost-effective product for market. Of course, in the real
world, things don't happen as they would in a model.
