The West African coastline is home tomajor industries, mining activities, peri-urban andagro-industry, and tourism, as well as urban and seasideresidences, all of which generate waste and cause pollution.Many areas along the coast also lack adequate wastewater andsolid waste management systems. As a result, large volumesof untreated wastewater and solid waste are dumped into theopen, polluting the land and water. Water quality studiescan help policy makers set targets and baselines and developpollution reduction plans at the local, national, andregional levels. Such studies generally focus on pollutionfrom sewage/wastewater, nutrients, and marine litter; theymay also include other pollutants, such as oil (spills fromships and offshore oil exploration and production),chemicals, and heavy metals. Reducing the generation ofplastic debris requires collect¬ing data on the origin,volumes, and types of plastic litter, so that appropriatemeasures can be taken to reduce the use of, reuse, orrecycle plastic products.
