The report provides an overview of the current state of knowledge in terms of the sources, relative contribution and data gaps when it comes to sea-based sources of marine litter. A section of the report is dedicated to fishing as a marine litter source.
Main findings of the report related to the fishing sector include:
- How does fisheries contribute to marine litter? Abandoned, Lost or otherwise Discarded Fishing Gear (ALDFG) is a major source of marine litter arising from the fisheries sector.
- What are the causes? Causes of ALDFG vary and include: Environmental; Gear/vessel conflict; regulations; IUU fishing; and operator error.
- How much? Crude historical estimates of ALDFG range from between 640,000 tonnes - 1,350 tonnes pa. The report identifies gaps and stresses the need for improved estimates.
- What is the impact? The impacts of ALDFG include: Economic losses; ghost fishing; habitat damage; and navigation hazard.
GESAMP is an advisory body consisting of scientific experts nominated by the Sponsoring Organizations (IMO, FAO, UNESCO-IOC, UNDP, UNIDO, WMO, IAEA, UN, UNEP, ISA). Its principal task is to provide scientific advice concerning the prevention, reduction and control of the degradation of the marine environment to the Sponsoring Organizations.
