Summary
This study assessed solid waste from small-scale fisheries (SSF) and households in Peru. Findings highlight the need for integrated waste management plans to protect public health and marine ecosystems.
Area of Science:
- Environmental Science
- Marine Biology
- Waste Management
Background:
- Small-scale fisheries (SSF) are vital for Peruvian coastal communities' food and livelihoods.
- Limited data exists on solid waste generation and management within Peruvian SSF and associated communities.
Purpose of the Study:
- To assess solid waste generation from gillnet SSF and households in San Jose, north Peru.
- To provide foundational data for developing integrated waste management strategies.
Main Methods:
- Monitored solid waste production during 22 fishing trips.
- Interviewed 70 families regarding household waste generation.
- Calculated daily waste and recycling per capita using Generalized Linear Mixed-Effect Models.
Main Results:
- Organic waste (38% fishing, 83% home) and plastics/metals are primary waste streams.
- Fishing activities also produce glass, paper/cardboard, and fishing nets.
- Estimated daily per capita waste: 0.14 kg onboard, 0.33 kg at home.
Conclusions:
- San Jose residents perceive solid waste as a threat to public health and marine ecosystems.
- This study is the first assessment of solid waste in a Peruvian fishing community.
- An integrated management plan for vessel and land-based waste is urgently needed.
