Monitoreo y análisis de macro basura en dos playas situadas en Data de Posorja, Ecuador

Abstract

Anthropogenic Marine Debris (AMD) pollution on sandy beaches poses significant risks to biodiversity, the economy, and human health. This study analyzes AMD on El Encanto and Club Alfón beaches in Data de Posorja, Ecuador, focusing on its composition, primary sources, and accumulation patterns influenced by geographic and human factors. Using a standardized methodology adapted from 'Científicos de la Basura,' five monitoring sessions were conducted from August to December 2024. The collected AMD was classified into seven categories, and differences between the beaches were assessed using non-parametric statistical tools. Results revealed that plastic was the dominant debris type (89.3%), followed by wood (7.9%) and other materials (1.7%). Club Alfón beach exhibited significantly higher litter density (1.97 items/m²) compared to El Encanto beach (0.88 items/m²), with more uniform distribution patterns. These findings suggest that AMD accumulation is shaped by seasonal and local dynamics, affecting both ecosystems and coastal economies.
