Ghana Working to Save Eroding Coastlines

Ghana has started building seawalls at key points along its shore to stop coastal erosion and protect beaches, communities and historic buildings. But fishermen say the walls make it hard to pull in their nets, while coastal resorts say the walls hurt their businesses.Ben Idun set up a resort in the coastal town of Elmina in 2009, imagining people would flock to its golden beach.  However, he has spent much of his time trying to stop rapid coastal erosion, which he attributes to years of illegal sand mining in the area.  When authorities finally stepped in the mining decreased, and to stop further erosion, a rocky sea defense wall was built on the shore in 2017. But this added more woes for the resort, as hotel guests can no longer access the water.As Ghana’s coasts erode, the government is putting up sea walls which some hotels say have a negative impact on business.

While some of the walls allow beach access, there are concerns about the walls’ impact and effectiveness.  While the sea defense walls have worked in the short term to stabilize the beach and protect properties, Dr. Angnuureng questions how they will hold up in the long run as the sea level rises with global warming.   While there needed to be measures put in place to save properties, he said other approaches should be considered.   “We can consider some soft solutions like vegetation, mangroves or just nourishment with sand. We can mix solutions, and we can have our beaches and even have gardens and proper recreational areas,” Dr. Angnuureng said.While some in the Central Region campaigned for the seawalls, fishermen such as  Christopher Ahorsu say they fear for their livelihoods, worried the sea walls will block them from doing their already precarious work.  “It will disturb us and all of  the time when we are pulling the nets, our minds go there – that’s all the work we do here, we don’t have any work, we do only the sea work that we do,” Ahorsu said.Ghana’s Central Region Minister Kwamena Duncan grew up in the area and has watched the coastline erode over the past 15 years. He said the walls are to protect livelihoods and are constructed to allow for the needs of the fishermen.Ghana’s Central Region Minister Kwamena Duncan says the walls are to protect livelihoods Oct 2, 2020.
