A regional collaborative approach in transboundary pollution management in the guinea current region of western Africa

The Guinea Current Large Marine Ecosystem extending from Guinea Bissau to Angola and covering sixteen countries in West and Central Africa and characterized by distinctive bathymetry, hydrography, chemistry, and trophodynamics with the Guinea Current as the unifying feature has remained a sources of global interest. With openness to the Atlantic Ocean and watercourses with access to the sea such as the Congo and Niger Rivers, the GCLME embodies some of the major coastal upwelling sub-ecosystems of the world and is an important center of marine biodiversity and marine food production ranked among the most productive coastal and offshore waters in the world. However, pollution from domestic and industry sources, over-exploitation of fisheries and poorly planned and managed coastal developments and near-shore activities are resulting in a rapid degradation of vulnerable coastal and offshore habitats and shared living marine resources of the GCLME putting the economies and health of the populace at risk. The deterioration in water quality (chronic and catastrophic) from land and sea-based activities (especially industrial, agricultural, urban and domestic sewage run-off and mining activities including the oil and gas sector), eutrophication and harmful algal blooms have been identified as a major transboundary environmental problem by the countries in the adopted Transboundary Diagnostic Analysis (TDA). Arising from the results of the various environmental and socio-economic studies and assessments conducted over the years as documented in the Transboundary Diagnostic Analysis (TDA), the countries resolved to adopt a holistic, multi-sectoral and regional approach embodied in the large marine ecosystem concept for transboundary pollution management in the region. The agreed management actions to be undertaken jointly by the sixteen countries are encapsulated in the adopted Strategic Action Programme to be implemented by the Interim Guinea Current Commission (and later the Guinea Current Commission), established by the countries as an intergovernmental consultation and coordination body, with the technical assistance and co-funding of the Global Environment Facility (GEF), the United Nations Industrial Development Organization (UNIDO), United Nations Development Programme (UNDP) and United Nations Environment Programme (UNEP).
