AI summary Read the abstract

This first assessment of marine litter on Somalia's Liido Beach found nearly 120,000 items, with plastics accounting for 89% of debris and a mean density of 6.25 items per square meter. Local recreational and shoreline activities were the dominant pollution sources, and the prevalence of plastic litter poses serious threats to marine biodiversity in the West Indian Ocean.

Study Type Environmental

This paper presents the first assessment of marine litter in the Mogadishu coastal area of Somalia. Samples were collected monthly using 100 m × 40 m transect and classified following OSPAR Marine Litter Survey Guide while litter sources were identified using Ocean Conservancy Marine Debris Index. The results showed a total of 119873 items consisting of plastics (89.47%), clothing items (7.53%), and others (3.00%) recovered from Liido Beach. Litter density ranged from 2.19 items/m2 to 14.18 items/m2 with a mean of 6.25 items/m2 and Clean Coast Index (CCI) suggesting that Liido Beach is extremely dirty (>20 items/m2). In addition, the primary sources of marine litter at the beach are local recreational and shoreline activities (54.12%), and dumping (36.61%). The dominance of plastic litter on the beach poses potential threats to marine biodiversity in the Somalia coastal area and the West Indian Ocean. It is recommended that effective strategies and solutions to mitigate litter on the beach and other coastal areas in Somalia should be developed and compensated with public education and awareness campaigns across the country.

Abundance, Characterization, and Distribution of Marine Litter in Samar, Philippines: A Comparison Between Mainland and Island Beaches

AI summary Read the abstract

A systematic beach litter survey in Samar, Philippines found plastic comprising 86% of mainland beach litter and 60% on island beaches, with shoreline recreational activities as the dominant source, revealing significant differences in contamination between coastal typologies. This study is directly relevant to microplastic research as high plastic litter density on Philippine beaches represents a major source of secondary microplastic generation through UV-driven fragmentation and mechanical weathering in the marine environment.
