Explanation: von Thunen's approach is still relevant today because his approaches still exist in the modern day but with few modifications.
Some of this factors considered are,
Dairying and intensive farming occur in the ring closest to the city: The people in the city mostly consume dairy product. The approach tells that to get good cost balance ratio,dairy farm should be located not too far from city to reduce transportation cost, this approach is still very effective because cost of transporting this produce from a far distance leaves farmers little or no gain. Promixity to end users is important especially when the products are heavier.
2. Crops- He made use of grains as example, grains are often not planted far away from cities because of animals that could feed on it and destroy the field, theft and because of required land mass to cultivate. He stated that grains are light weight and could require low cost of transportation compare to dairy products. This is still important because transporters charged mostly per kg of goods, the weight of grains are lighter reduced the cost of transporting if located in far distance and also it helps reduce risk of loss.
3.Animal-animals can be moved without any means of transporting. Hence, when Ranch is located far from the city where the sales occur the cost of transportation is not a burden.
All this makes von Thunen's still relevant
