Architecture student Magnus Larsson wants to turn some of the most deserted and harsh landscapes on the planet into habitable structures. How? By turning loose sand dunes into solid architecture using bacteria. A team at UC Davis has been looking at the microorganism bacillus pasteurii to solidify the ground in earthquake-prone areas. As Larsson puts it, "All I did was to deliberately misapply their technology ... and to pump up the scale, and turn it into a 6,000-km-long wall that's made of sand and protects against sand."

After talking with Jason DeJong at UC Davis and with Stefano Ciurli, a b. pasteurii expert at the University of Bologna, Larsson put together a team at University College London to grow the bacteria and attempt to solidify sand. His Holcim Award-winning proposal is a complement to the Green Wall Sahara shelterbelt, being planted across the African continent. Larsson is now investigating how to bring the project to the next stage: a 1:1 scale prototype.

"One of the most interesting aspects of the project, I think, is that this solidified dunescape is created through a particularly novel form of ‘sustainable construction' -- that is, through a kind of infection of the earth."
