Marine Ecosystem Protection Trade-off Economic Model with Terrestrial Ecosystem Exploitation in Fishing Communities Near Marine Protected Areas

TL;DRAbstract

The total ban on fishing in marine protected areas demands entailed that fisherman in nearby fishing communities look for an alternative means of livelihood. Often, such alternative livelihoods exploit the remaining terrestrial ecosystem found within or near these fishing communities. This paper introduced a trade-off economic model for marine protection-terrestrial exploitation through a Marine Protection Terrestrial Exploitation Curve (MPTEC). The peculiar characteristics of the fishing communities near marine protected areas (MPAs) are inputted to the trade-off model. Simulation results revealed that for the optimistic case (communities which are better educated and with small household sizes), the terrestrial ecosystems’ damage rate ranged from 3.7% to 28% for MPA sizes ranging from 3 hectares to 30 hectares, while in the worst case scenario (communities which have 6 years or less of schooling and with larger household sizes), the estimated damage rates for the terrestrial ecosyste
