2005年,非洲23个国家共同发起了[the Green Wall Sahara]行动计划,希望在撒哈拉里建起一条绿色的长城。不过一个很大的问题是,这些树木很有可能会被当地的人砍来当柴烧。

为此,建筑师Magnus Larsson提出了另一个方案。





Why you should listen to him:

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 ‚Äòsustainable construction’ — that is, through a kind of infection of the earth.”

DUNE: Arenaceous Anti-Desertification Architecture


Born in Sweden in 1976, Magnus Larsson now lives and works in both Stockholm and London. With a BA (hons) in architecture from the Oxford (Brookes) School of Architecture, he is currently finishing off his diploma studies at the Architectural Association.
With a background in journalism and advertising, Larsson has contributed as a writer to publications including Frame, The Wire, Another Magazine, Kultureflash, and Bon International, and has written features in his native tongue for magazines and newspapers including Dagens Nyheter, Expressen, Arkitektur, Rum, and Forum. He has supplied copy for brands such as Apple, Absolut Vodka, and Sony Ericsson, and won a bronze cyber lion at the advertising festival in Cannes for a campaign he came up with and wrote while being Senior Copywriter at London interactive agency, Abel & Baker.
Before that, he founded and became the editor-in-chief of the Swedish literature magazine Mono. Worked as editor of several magazines and websites, including one on the underground music and clubbing scene in Stockholm: Started the hip hop club, Backspin. Was headhunted to become the Nordic Editor of boom, the infamously never-published international webzine of equally infamous failure – a position that brought him to London in the late 1990s.
Larsson has translated books from Swedish to English, written a book on colour theory for boutique hotel Nordic Light, and worked for a year in the office of Swedish architect, Erik Andersson. In parallel with his architecture studies, he’s designed a wine bar for an upmarket restaurant in Stockholm, as well as an office space for a travel agency in London.
At the Architectural Association, he’s designed with surface equations in diploma unit 5 under the tutelage of George Legendre, and proposed a 6,000km long wall made of solidified sand in diploma unit 16, which won him a 2008 ‘Next Generation’ Holcim Award, as well as some recognition from the likes of BLDGBLOG, Wired, and Slashdot. He is currently trying to rethink iconicity in diploma unit 9 (Natasha Sandmeier and Monia De Marchi), through the implementation of a 180m tall loadbearing brick skyscraper hotel in Manhattan, based on the corner as spatial generator.
