Resumen

Anthropogenic contamination in marine-coastal ecosystems remains one of the most pressing environmental challenges globally. In Peru, despite the significant presence of fish processing activities, there is a lack of comprehensive assessments regarding the generation and management of solid waste from this sector. This study focuses on the Santa Rosa District in the Lambayeque region, analyzing the risk of contamination caused by fish industry waste discharged into the Pacific Ocean through Drain 4000, covering an area of approximately 16 km2. Utilizing 455 Sentinel-2 L2A satellite images from 2018 to 2023 and remote sensing techniques integrated with GIS tools, we developed contamination risk maps that highlight the most vulnerable zones. The combination of these technologies enables a spatially detailed, timely, and cost-effective method for environmental monitoring. Results indicate that the areas surrounding the fish processing facilities in Santa Rosa are at high risk of contamination, posing serious ecological and socio-economic threats. These insights provide a foundation for targeted environmental policies and improved waste management strategies in the region.
