Nigeria is the most populated country in Africa with more than 230million people living there. Lagos, the country’s largest city, has a population of 23million people, and is one of the most congested places on Earth.
However, an ambitious new plan in the city plans to expand Lagos so that it can accommodate a staggering 88 million people expected to be there by 2100.
Over the last 100 years, Lagos has lost nearly two miles of its coastline due to erosion.

Under the proposal, Lagos could be expanded with 10 new city districts that will house more than 250,000 residents.
Engineers are even planning to build what they call the “Great Wall of Lagos” – an eight kilometres long and 45 metre wide structure that rises 18 metres from the ocean floor.
