2. BASIC TERMINOLOGIES
• 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 farming: Intensive farming or intensive agriculture
is a kind of agriculture where a lot of capital and labor is
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. 2Prepared by Wesley
3. CONT……..
• Extensive farming: 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.

4. INTRODUCTION
• The agricultural land use model was developed by JOHANN
HEINRICH VON THEUNEN (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 known as “concentric rings
theory of agricultural land use.”
• The model has 4 rings which developed around the central
city. Each ring shows a different type of agricultural land use.
• Von Thunen’s model was created before industrialization,
highways, railroads, factories, etc. came into light.
4Prepared by Wesley
7. CONT……
• According to Von Thunen’s model, the relative cost of
transport for different agricultural commodities to the
central market determines the agricultural land use in
the city.
• The most productive activities will be closest to the
center market and the activities not productive
enough will be located away from center city.

8. ASSUMPTIONS
1. The land must be isotropic with no river, mountain etc.
2. The isolated state is surrounded by an occupied wilderness.
3. The soil quality and climate are consistent throughout the
state.
4. The transport cost is proportional to the distance.
5. All farmers have equal access to transport.
6. All the farmers are economically rational.
7. All farmers have equal information regarding market
demands, cost of production and they all attempt to
maximize profits.

9. EXPLANATION OF VON THUNEN’S MODEL
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.
9Prepared by Wesley
10. CONT………
3. The third zone consists of extensive field crops such as
grains for bread. Since grains last for longer periods than dairy
products and also lighter than wood, their transport cost will
therefore be lower allowing its production to be 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 in a
greater distance from the central city for any type of
agricultural product. 10Prepared by Wesley
12. BID RENT CURVE (Economic Rent)
NB: As distance from the city center increase, the cost of
the land reduces
12
Prepared by Wesley
13. CONT………..
• 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. 13
Prepared by Wesley
14. EXPLANATION
• All agricultural land users 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.
14Prepared by Wesley
15. CRITICISM ON MODEL
•Different 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 affect agricultural location.

16. CONCLUSION
Even though the Von Thunen model came into light in time
before introduction of factories, highway and even railroads, it is
still an essential 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
increase. Farmers should balance the cost of transportation, land
and profit and focus on producing the most cost-effective
products for the market so as to receive greater profits.
