GPA Pollutant Source Categories

In 1995 over 108 governments declared “their commitment to protect and preserve the marine environment from the impacts of land-based activities …. Setting as their common goal sustained and effective action to deal with all land-based impacts upon the marine environment, specifically those resulting from sewage, persistent organic pollutants, radioactive substances, heavy metals, oils (hydrocarbons), nutrients, sediment mobilization, litter, and physical alteration and destruction of habitat.

The 2006 report entitled “The State of the Marine Environment – Trends and processes”, prepared for the 2nd Intergovernmental Review of the GPA in Beijing, China, states:

“An overall assessment of the situation concerning land-based sources of pollution and progress in implementation of the GPA shows that while the framework for action is solid, progress in dealing with the nine source categories has been uneven. There are three areas where good progress has been made (Persistent Organic Pollutants, Radioactive Substances, Oils (Hydrocarbons), two areas where results were mixed (Heavy Metals and Sediment mobilization) and yet a third group where conditions have worsened (Sewage, Nutrients, Marine Litter, Physical Alteration and Destruction of Habitats).”

As per the guidance provided by the Intergovernmental Review of GPA (GR2), and in line with  UNEP Marine and Coastal Strategy - Executive Summary (2010) the GPA programme is focusing its efforts for 2007-2011 on wastewater, nutrient management, marine litter and physical alteration and habitat destruction (PADH).

GPA collaborated with global, regional and national partners in the implementation of activities addressing the pollutant source categories.
