Idris Elba, one of the actors rumoured to be the next James Bond, is leading a project to turn an island in Sierra Leone into an eco-city. The new plans for Sherbro Island include wind-powered renewable electricity, solar farms and a film studio. The hope is that the island will become a tourist destination for people seeking the sun.

The BBC’s David Waddell spoke to Elba about his new project. David joins us to explain the actor’s motivations and his vision for the city.

But we can’t not mention Akon City! Grammy award-winning artist Akon also has plans to transform a part of Africa. In 2018, the Senegalese-American said he would build ‘Akon City’ on the coast of Senegal. The R&B star said he wanted to create something like Wakanda from Marvel’s Black Panther. However, the project has been hit by delays and has barely got off the ground. Borso Tall, a journalist based in Senegal, takes us though the latest.
