USAID Marine Litter Audit Guidebook

The guidebook provides a standardized approach for conducting a marine debris beach litter survey to measure the rate, extent, and composition of litter on beaches. It outlines the equipment and software requirements, survey zones, and methodology for data collection and analysis. The guidebook is intended to be used by local government staff, partners, and commercial establishments to understand and prevent litter at its source and develop social and behavior change outreach programs for their communities.
