Which economic model explains agricultural land use patterns based on distance from a central market?

• A. Von Thünen Model
• B. Demographic Transition Model
• C. Bid Rent Theory
• D. Central Place Theory

Answer: (A)

Distance from a central market determines profitability of different crops and farming practices because moving goods farther adds cost. The Von Thünen model envisions a single market town at the center with concentric rings around it. Close to the market, farmers grow products that are perishable or high-value and costly to transport, since it’s worth paying more to keep them near market. As you move outward, transport costs rise, so land is used for goods that are cheaper to move in bulk or less time-sensitive. This creates a pattern: intensive, high-value crops near the center, then forest for fuel and building materials, then grains, and finally grazing or ranching farther out where transport costs are least burdensome. The model shows how land use changes with distance to minimize costs and maximize profits given transportation. Other models don’t fit this specific agricultural pattern. Bid Rent Theory focuses on how land value changes toward a city center for urban activities, not concentric agricultural zones. Central Place Theory explains the size and spacing of settlements and their market areas, not how agricultural land use shifts with distance from a single market. The Demographic Transition Model describes stages of population and growth over time, not land use around a central market.
