Magnus Larsson has an ambitious plan to re-landscape the Sahara Desert--and do so sustainably. The images in the gallery above depict Larsson's vision of a 6,000-km green wall made of sandstone, which would provide shelter and protection--as well as hedge against the spread of the desert.
What's fascinating about Magnus Larsson's idea is that it is completely sustainable. All the Sahara architecture needs is bacillus pasteurii, a microorganism that solidifies loose sand into sandstone.
Magnus Larsson's idea won first prize at the Holcim Foundation's Awards for Sustainable Construction. Check out more photos from the project here.
