Abstract

The highest demand for ecosystem services for human activities around the world, come from the coastal marine zone (CMZ). In areas with poor management, this can have consequences in the loss of the environments and ecosystem services. The aim of the study was to develop scenarios for the management proposal for the coastal marine zone (CMZ) between Pacocha (Moquegua) and Morro Sama (Tacna) in Peru. The study area extended five kilometers inland from the coastline and encompassed a marine zone stretching five miles offshore. The development of the management proposal was based on the identification and mapping of the area's ecosystems, the ecosystem services they provide, and the pressures exerted on them by human activities. To develop the management proposal, the Marxan with Zones program was utilized. The model incorporated the identified ecosystems, ecosystem services, ecosystem pressures, and the presence of natural mollusc banks and rivers. The modeling process resulted in the implementation of four management zones: Protection, Preservation, Sustainable Use, and Recovery. The Sustainable Use zone was the largest, covering 30% of the total area, while the Recovery zone was the smallest, occupying 16%. These results can serve as a valuable tool for decision-makers in implementing an Integrated CMZ plan.
