Fig. 7. Total accumulated global returns at the end of the simulation period (yr 200) with change in the maximum total number of fields (centralized) or maximum number of fields/farmer (decentralized) for the a) centralized and b) decentralized models without fishing, and c) decentralized with fishing. D) Comparison of the total accumulated global returns at the end of the simulation period of the centralized, decentralized without fishing and decentralized with fishing for a run with maximum number of fields/farmer = 20.
