The concept explains agricultural land use patterns based on transportation costs and market prices. It posits that agricultural activities are arranged concentrically around a central marketplace, with land use intensity decreasing as distance from the market increases. The model assumes a single market, uniform landscape, and farmers seeking to maximize profit. For example, activities like dairy farming and market gardening, which involve perishable goods and high transportation costs, are located closer to the market. Extensive farming practices, such as grain cultivation, are situated further away due to lower transportation costs relative to their value.

Its significance lies in providing a foundational understanding of spatial economic relationships and factors influencing agricultural land distribution. It highlights the role of transportation costs in shaping economic landscapes and offers a framework for analyzing regional variations in agricultural production. Historically, it has been a cornerstone in agricultural economics and geography, influencing subsequent models and theories related to location decisions and land use planning. Its benefit is to have a method of understanding the distribution of products.

The agricultural land use model, developed by Johann Heinrich von Thnen, explains and predicts agricultural land use patterns in a theoretical state. This model, often examined in the context of Advanced Placement Human Geography, posits that specific crops and livestock are raised in concentric rings around a central marketplace. The determining factor for land use is the economic rent, which is the difference between the value of a product and the cost of producing it, including transportation to the market. High-value, perishable goods or those expensive to transport are located closer to the market, while less perishable and less transport-sensitive goods are produced further away.

The model’s significance lies in its ability to illustrate the interplay between transportation costs, land value, and agricultural decision-making. It provides a foundational understanding of spatial economic principles and helps to explain why certain agricultural activities cluster in specific locations. Historically, this framework offered valuable insights into agricultural practices before modern transportation infrastructure and globalized markets significantly altered these patterns. It serves as a valuable tool for understanding the forces shaping land use and agricultural landscapes.
