What does the theory of Von Thunen say?

The theory of Von Thunen, proposed by German economist Johann Heinrich von Thünen in the 19th century, suggests that agricultural land use is influenced by transportation costs. It states that different types of agricultural activities are arranged in rings around a city, with higher value and perishable crops located closer to the city center due to lower transportation costs, while lower value and less perishable crops are located further away.
