Relationship between Solid Waste Pollution, the Clean Coast Index, and Recreational Suitability at Los Yuyos Beach, Lima–Peru

Abstract

Solid waste pollution on beaches represents a global environmental challenge that affects ecosystems, public health, and the quality of recreational activities. This study evaluated the relationship between the level of pollution and visitors’ perceptions at Los Yuyos Beach, located in Barranco, Lima, Peru. A quantitative approach was employed through the delimitation of 30 quadrats measuring 4 × 4 meters distributed along the beach to identify critical points of waste accumulation. The level of cleanliness was determined using the Clean Coast Index (CCI) during the winter and summer seasons, complemented by surveys based on the Recreational Suitability scale to measure users’ perceptions. The results showed a greater predominance of plastic waste, such as single-use bags and PET bottles, in winter, whereas organic waste was more prominent in summer. The highest accumulations were found in areas with vegetation and natural drainage. The CCI classified the beach as moderately clean in winter and adequate in summer. The average perception score was 0.5 in winter and 0.9 in summer. A significant inverse correlation was identified (r = −0.782; p < 0.001) between perception and pollution levels, indicating a strong association between environmental quality and recreational valuation. These findings highlight the importance of strengthening waste management to improve environmental quality and recreational experience.
