At zero distance the rent is the highest; 1. As we move away from the center the rent drops substantially since the amount of available land increases exponentially. There is more land available to bid on, so if the supply goes up, the price usually goes down. This rent/distance relationship has an impact on land use.

Thus bid-rent theory gives emphasis on the direct relation between transport cost and land use intensity which is not exactly applicable in all urban spatial pattern. Other aspects like physical, resources, accessibility, multiple service centers are the determining factor of urban land use.

Explanation: closer to coast more expensive farther away from coast less expensive. Example: I want to put up a shop so i will choose somewhere away from the coast.

Johann Heinrich von Thünen

One of the most fundamental components of urban economics is the rent gradient. The rent gradient is in essence the slope of the bid-rent function. The rent gradient is: (Change in Rent/Change in Distance) = (-Commuting Cost(C)/Lot Size(L)) The bid-rent function displays how rents change with distance to the CBD.

Bid Rent for land can be determined by seeing how much revenue is “left over” using formula on p. 181. Rent = TR – K (non-land costs). In this case, the TR is $2400 [4 houses at 600 each] – non land costs of 200 per house or 800..

The bid rent theory is a geographical economic theory that refers to how the price and demand for real estate change as the distance from the central business district (CBD) increases. It states that different land users will compete with one another for land close to the city centre.

Long-haul economies of transportation will also affect the shape of the bid-rent curve. A 5-mile trip to the urban core cost more than one-half of a 10-mile trip because of fixed costs associated with both trips and higher congestion costs nearer the CBD that increase time costs.

This is because most of the main transport routes lead here. Due to high land values, buildings tend to be tall and building density is high. Land values tend to be very high, this is the result of great competition to locate here. It is cheaper to build up than out.

Main Idea: Focuses on how price and demand for land changes as the distance from the central business district increases. The most expensive land is in the central business district because it has the greatest access to people.

The Von Thunen Model attempts to differentiate between land use patterns based on the different scales of agricultural production. More specifically, it relates transportation costs to distance from the market in an attempt to further explain rural land use. More intensive rural land-uses closer to the marketplace.

In the time since von Thünen, changes in communications and transportation technologies and progress in food preservation methods, such as refrigeration, have changed the significance of some of his theory’s variables. However, the basic concepts of the von Thünen model are still valid.

The Von Thunen model is still relevant today in spite of its weaknesses because it can be used as an idealistic depiction of agricultural geography, particularly in its representation of how land and transportation costs relate to markets.

Von Thunen’s model was created before industrialization and is based on the following limiting assumptions: The city is located centrally within an “Isolated State” which is self sufficient and has no external influences. The Isolated State is surrounded by an unoccupied wilderness.

3) land is generally flat, 4) soil quality and climate are consistent, 5) farmers transport goods to a market using mainly carts, and. 6) farmers behave rationally in choosing where to conduct their activities.

What is the Von Thünen Model? A model explains & predicts where and why various agricultural activities would take place around a city’s market place. A central marketplace is surrounded by agricultural activity zones that are in concentric rings – each ring represents a different type of agricultural land use.

Which of the following is the most often cited environmental benefit of the eat-local movement? Less fossil fuel is used in transporting food to market.

Tropical regions are rich in forested landscapes, where multiple species of animals and plants live. The agricultural practice that most significant long-term environmental impact is to burn these areas to create pasture.

Which aspect of von Thunen’s Model has changed as a result of developments in transportation? The market is no longer at the center. The width of the rings has increased.

A (animal waste is an important concern in both aquaculture and feed lots)FRQ #1 (A-G)A)Intensive land use is when there is a lot of labor involved and high costs; extensive land use is an agricultural system that involves little labor, fertilizers, and capital relative to theamount of land being farmed.

A crop rotation can help to manage your soil and fertility, reduce erosion, improve your soil’s health, and increase nutrients available for crops.

Terracing, which is basically grading steep land, such as hillsides, into a series of level benches,… Terrace cultivation has been practiced in China, Japan, the Philippines, and other areas of Oceania and Southeast Asia; around the Mediterranean; in parts of Africa; and in the Andes of South America for centuries.

Answer. The terrace farming practised in hilly areas ’cause in hilly regions the water will not be properly holded and will flow away. Therefore, the terrace are made to hold the water properly and which will be easier for cultivation of crops. Hence, terraces are very useful in farming practices in hilly regions.

Today, modern farmers are returning to the terrace farming practices used thousands of years ago as a more practical and productive way to raise the most food with the least water. Tea farmers also take advantage of terrace farming.
