Resumen

The highest demand for ecosystem services for human activities worldwide comes from the coastal marine zone (CMZ). In areas with inadequate management, this demand can lead to the degradation of ecosystems and the loss of the services they provide. This study aimed to develop management scenarios 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 area stretching five nautical miles offshore. The development of the management proposal was based on the identification and mapping of local ecosystems, the ecosystem services they provide, and the pressures exerted by human activities. To support this, the Marxan with Zones program was used, incorporating data on ecosystems, ecosystem services, human-induced pressures, as well as the presence of natural mollusks banks and rivers. The modeling process resulted in the proposal 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 provide valuable support for decision-makers in implementing an integrated CMZ management plan.
