Magnus Larsson: Turning Dunes into Architecture
In this talk, courtesy of TED, architecture student Magnus Larsson details his bold proposal to build a 6,000-kilometer-long wall across the entire African continent. He aims to use Bacillus pasteurii (microorganisms that create sandstone) to solidify the sand and to help provide shelter for individuals and curb the destruction caused by desertification. Larsson describes how sand dunes in Northern Nigeria move southward at a pace of around 600 meters a year. In this way the Sahara destroys almost 2 meters of arable land a day, physically pushing people away from their homes. Using these microorganisms, Larsson plans to create habitable spaces within the sand dunes which provide good spatial qualities, ventilation, and thermal comfort as well as stopping the sand dune from moving forwards.
