Developing a Citizen Science Approach to Monitor Stranded Marine Plastics on a Remote Small Island in Indonesia
AI summary Read the abstract
A citizen science monitoring program was developed with villagers on a remote Indonesian island to track stranded marine plastics, finding 3.97 kg per square meter per week with 58% being plastic. Collected recyclable plastics provided supplementary income equivalent to about 13% of average monthly household income, demonstrating that community-based monitoring can combine environmental and economic benefits.
ABSTRACT Marine plastics stranded on the coastlines of remote small islands threaten both the ecological integrity of local ecosystems and communities’ well‐being. However, despite the growing quantities of stranded plastics in these locations, the remote nature of these sites renders monitoring and intervention efforts difficult to undertake. Within this context, we developed a citizen science approach to monitor stranded marine plastics in collaboration with villagers living on a remote small island in Indonesia. This study reports the co‐development and application of an approach that can be used and maintained independently by remote coastal communities. In the monitoring stage, the participants quantified both the weight and composition of stranded marine debris on a beach located in their village for a 4‐week period from late May to mid‐June 2021. The results revealed that the weekly accumulation of stranded marine debris on the beach was 3.97 kg/m 2 , with 58% categorized as plastics. The stranded plastics sampled in this study were sorted and collected for recycling, estimated to provide a total economic value of 91,700 Indonesian Rupiahs (USD 5.84), or equivalent to 12.77% of the average monthly household income in the area. The citizen science activities indicated that the local villagers were capable of operating the designed monitoring system effectively, with the added benefits of supplementary earnings from recycling. An independently operated monitoring approach combined with collection efforts for recyclable items is important as remote islands have to manage increasing quantities of stranded marine debris despite the lack of an adequate local waste management system.

Rapid spatiotemporal monitoring of beach microplastics in the Galápagos Islands
AI summary Read the abstract
This study tested whether citizen scientists — local teenagers in the Galápagos Islands — could reliably monitor beach microplastics using a portable near-infrared spectrometer, finding that 93% of particles were correctly identified as plastic and showing that microplastic concentrations on Tortuga Bay increased significantly in 2024. The citizen science approach generated five years of spatiotemporal data that would otherwise be impossible to collect in such a remote location. This matters because low-cost, community-based monitoring could fill major gaps in global microplastic surveillance, especially in ecologically sensitive and hard-to-reach areas.

Researchers assessed microplastic ingestion by freshwater mussels deployed as sentinel organisms at multiple river sites, finding particle accumulation that reflected local contamination levels. Transplanted mussels at polluted sites accumulated significantly more particles than those at clean reference sites within a six-week exposure period, validating their utility as biomonitors.

This citizen science study used a standardized methodology to monitor floating plastic debris off the Cornish coast of the UK, finding microplastic concentrations comparable to or higher than other European coastal regions. The study demonstrates that citizen science can generate useful, standardized data on plastic pollution in coastal waters.
