Every day, several tons of waste are produced in the Nigerian megacity of Lagos. In the early 1990s, in order to control this amount, the city council designated a remote area of 100 acres where the Olusosun landfill site was built. As the population has more than tripled since then, the area is now surrounded by inhabited settlements and was closed at the beginning of 2018 due to health risks. Now, the area is to be repurposed as a green space and public park. The competition is looking for concepts on how a stadium could be integrated there. These structures are themselves often a challenge in terms of resources, irregular use, and lifespan, which is why they are intended to serve as an example for the innovative handling of waste production. The first prize is endowed with 5,000 US dollars, the second prize is shared by three submissions receiving prize money of 1,000 US dollars each.
