Step 1: Define co-operative farming. It is a system where farmers in a community pool their land, machinery, and other resources to increase efficiency and profits.
Step 2: Evaluate the success of co-operatives in the given countries. While co-operative movements exist in many countries, they have been exceptionally successful in several Western European nations. Denmark, in particular, is a textbook example where the co-operative movement revolutionized its agriculture, especially in the dairy and bacon industries, making it highly efficient and competitive on the global market.
