Date and Time:

The unprecedented recent invasion of Sargassum seaweed on coastal shores in West Africa is being attributed to factors that include warming of the ocean due to global climate change, discharge of macronutrients (nitrogen and phosphorus forms) from agricultural run-off and wastewater originating from point sources and from major river basins such as the Congo and Amazon Rivers, and the deposition of iron and nutrient-rich Saharan dust on the ocean.

The third Sargassum webinar will focus on the West Africa region, where Sargassum is becoming a regional phenomenon, negatively impacting aquatic resources, fisheries, waterway, and shorelines.

This webinar will feature leading experts from affected countries in the region (Benin, Côte d’Ivoire, Ghana, Guinea, Liberia, Nigeria, Senegal, Sierra Leone, and Togo) at local and international organizations working on marine and coastal biodiversity management to share information, build knowledge on the phenomenon, promote best practice and develop ocean governance arrangements in combating the Sargassum phenomenon in West Africa.
