Introduction

This chapter notes explores the Von Thunen Model, a 19th-century economic framework that explains the spatial organization of agriculture based on transportation costs and market proximity. Developed by Johann Heinrich von Thunen, the model illustrates how different agricultural activities are arranged in concentric zones around a central market, influenced by profitability and land use intensity. It provides insights into the economic factors shaping agricultural patterns, despite its simplified assumptions.

Von Thunen Model

• The Von Thunen Model is an economic framework created in the 19th century to describe the spatial arrangement of agricultural activities, emphasizing the role of transportation costs. Developed by Johann Heinrich von Thunen, a German economist and landowner, the model explains how the location of farms relative to a market influences agricultural practices.

• According to the model, the spatial organization of agriculture depends on a farm’s distance from the market and the associated transportation costs. Farms closer to the market are more profitable due to lower transportation expenses and the ability to sell products at higher prices. These farms tend to focus on high-value crops or livestock that yield greater profits.
• Conversely, farms located farther from the market face higher transportation costs, making them less profitable. To compete with closer farms, they must sell products at lower prices, leading them to produce low-value crops or livestock that are less affected by price fluctuations.
• The Von Thunen Model predicts the spatial distribution of various agricultural activities and their relative profitability. Although it is a simplified model that does not account for factors like natural resources or infrastructure, it remains a significant tool in economics for studying the spatial organization of agriculture and other economic activities.

It predicts:

• More intensive rural land-uses closer to the marketplace:
  • Example: Commercial farming of milk (dairying): Dairy farms are located near urban areas to reduce transportation distances and costs, preventing spoilage of milk. These farms require less land, allowing them to afford the higher land prices near markets.
• More extensive rural land-uses further from the marketplace:
  • Example: Ranching: Livestock ranching requires large areas for grazing, so these farms are situated farther from markets where land is abundant and cheaper. When the model was developed, livestock were driven to market “on the hoof,” eliminating the need for refrigeration and reducing transportation costs.
• These rural land-use zones are represented by concentric rings in the model.

Examples

The Von Thunen Model can be applied to understand the spatial organization of agriculture through examples like:

• A farmer cultivating high-value crops, such as vegetables or fruits, may choose to locate their farm near the market to benefit from higher prices and lower transportation costs.
• A farmer raising livestock, like cows or pigs, may opt for a location farther from the market, as transportation costs are a smaller portion of production expenses. These farms may produce lower-value products, such as feed grains, for local markets.
• A farmer growing non-perishable crops, like grains or oilseeds, which can be stored for long periods, may locate farther from the market to take advantage of lower land and labor costs. These crops can be transported over long distances without spoiling, making transportation costs less critical to profitability.
• A farmer producing perishable crops, such as fresh vegetables or flowers, may choose a location closer to the market to minimize transportation costs and ensure products reach the market in good condition.

The Four Zones

The Von Thunen Model divides agricultural land into four concentric zones around a central city, which forms the solid core (not counted as a ring):

• Zone 1: Intensive agriculture and dairying: This zone includes fresh milk, dairy products, and certain fruits and vegetables. These perishable, high-demand products are produced close to the market to avoid spoilage. The farmland in this zone is highly sought after due to its accessibility, making it very expensive.
• Zone 2: Forest: This zone focuses on firewood and fuel production. When the model was developed, forest products were in high demand for building and fuel, requiring proximity to the market due to the difficulty of transporting heavy loads over long distances.
• Zone 3: Extensive field crops: This zone includes grains for bread, which require large areas for cultivation and harvesting. These crops are durable, lightweight, and easy to store, allowing them to be produced farther from the market, as they are cheaper to transport than forest resources and less perishable than dairy products.
• Zone 4: Ranching: This zone features abundant, inexpensive pastureland for livestock grazing. Livestock were raised and driven to the city market “on the hoof,” reducing transportation costs over long distances.

Summary of Zones

In the Von Thunen Model, agricultural land is organized into four zones based on distance from the market and transportation costs:

• The first (inner) zone: This zone is the most profitable due to its proximity to the market and low transportation costs. Farms here typically produce high-value, price-sensitive crops or livestock, such as vegetables or fruits.
• The second (outer) zone: Less profitable than the first zone due to higher transportation costs, this zone may focus on lower-value crops or livestock, such as feed grains or dairy products, which are less sensitive to price changes.
• The third (outer) zone: Even less profitable due to its greater distance from the market and higher transportation costs, this zone may produce crops or livestock like livestock feed or lumber, which are less affected by price fluctuations.
• The fourth (outer) zone: The least profitable zone, located farthest from the market with the highest transportation costs, this zone may produce crops or livestock like timber or timber products, which are minimally sensitive to price changes.

It’s important to note that the Von Thunen Model is a simplified framework and does not account for real-world factors like natural resources or infrastructure. Nevertheless, it remains a key conceptual tool in economics for analyzing the spatial organization of agriculture and other economic activities.

Assumptions

The Von Thunen Model relies on several assumptions, including:

• The cost of transportation increases linearly with distance, meaning transportation expenses rise proportionally as distance grows.
• The market is located at the center of a circular agricultural region, ensuring all farms are equidistant from the market.
• There is no transportation between different zones, meaning goods are only transported between farms and the market, not between farms in different zones.
• There are no externalities, implying that production and transportation have no environmental or economic impacts on other activities.
• Land is used exclusively for agricultural production, with no competing uses like urban development or recreation.
• There is a single dominant agricultural activity, meaning all farms in the region produce the same crop or livestock type.

These assumptions simplify real-world conditions and may not always hold true. However, the Von Thunen Model remains a valuable tool for understanding the spatial organization of agriculture and other economic activities.

In Short

• Transportation costs determine agricultural activities and their spatial arrangement.
• The model consists of a central city and four concentric zones (the inner two are intensive, the outer two are extensive):
  • Center City (solid core)
  • Dairying and Intensive Agriculture
  • Forest
  • Extensive Field Crops
  • Ranching
• Main assumptions for this model:
  • Flat land
  • One centrally located city
  • No disturbances to the economy

Important Part of Von Thunen Model

Key points about the Von Thunen Model include:

• The Von Thunen Model is a 19th-century economic framework designed to explain the spatial organization of agriculture based on transportation costs.
• It highlights how a farm’s distance from the market and transportation costs shape agricultural activities.
• The model divides agricultural land into four zones based on market distance and transportation costs. The first (inner) zone is the most profitable due to low transportation costs, while the fourth (outer) zone is the least profitable due to high transportation costs.
• The model relies on assumptions such as linear transportation costs, a centrally located market, no inter-zone transportation, no externalities, exclusive agricultural land use, and a single dominant agricultural activity.
• While simplified and not accounting for real-world factors like natural resources or infrastructure, the model remains a significant tool in economics for studying the spatial organization of agriculture and other economic activities.
