Africa’s oceans are vital for economic growth, supporting fisheries, tourism, and coastal livelihoods. But the costs of plastic pollution in our seas are mounting. The World Bank puts the cost of the damage caused by marine plastic pollution at up to US$33,000 per tonne of plastic waste, in West Africa alone. As pollution worsens, researchers say stronger policies, community engagement, and scientific collaboration can protect marine ecosystems in the region. In this episode of Africa Science Focus, reporter Michael Kaloki hears from researchers about the diverse ways to conserve the region's oceans and their ecosystems Despite existing policies to protect Africa’s oceans, implementation remains weak. Juliet Koudonu, a marine biologist at the University of Cape Coast, Ghana, says there is lack of enforcement and stresses that policies alone won’t drive change without government investment and accountability. For conservation efforts to succeed, policies must align with the needs of coastal communities, says marine social scientist Danai Tembo, a researcher in ocean governance at Nelson Mandela University, South Africa. She warns that laws failing to reflect local identities and livelihoods can backfire. Effective conservation requires scientists and local communities to work together. Shehu Akintola, professor of fisheries at the Lagos State University, Nigeria, believes it is important to integrate traditional knowledge with scientific research. The researchers say the continent can protect its marine resources for future generations by enforcing policies, empowering communities, and fostering scientific collaboration. ------------------------------------------------------------------------------------------------------------ This podcast was supported by the Science Granting Councils Initiative which aims to strengthen the institutional capacities of 18 public science funding agencies in Sub-Saharan Africa.
