In the Von Thünen model, what drives the pattern of land-use rings?

• A. Transportation costs to the market city determine the ring placement.
• B. Population density alone.
• C. Climatic variations.
• D. Policy constraints.

Answer: (D)

Transportation costs to the market city determine the ring placement. In the Von Thünen model, land around a single market town is uniform, so the most profitable use of land at each distance depends on how expensive it is to move goods to that market. Close in, high-value or perishable crops (requiring quick delivery) make sense, while as distance grows the higher transport costs favor different uses that are cheaper to move or produce in bulk. This creates a series of concentric zones, with land rent and transport costs shaping which crop or activity dominates each ring. Population density, climate variations, or policy constraints aren’t the driving mechanism in the original model; they can influence real-world outcomes, but the ring pattern fundamentally arises from the changing cost of transporting goods to the market.
