Amongst the Future Project Shortlist in the twelfth edition of the World Architecture Festival are a number of schemes designed to play a major role in creating a more sustainable future. These include a tower which uses algae to produce clean air, to tackle the vast dust cloud which plagues Beijing; repurposed oil tanks creating a new eco-park to restore destroyed habitats in Brooklyn; affordable modular water dwellings for Bergen in response to growing risks of flooding; a surge protection system to counter rising sea levels in Houston; the first energy positive airport city in the world for Oslo; and a residential community incorporating a large forest ecosystem reconnecting people with nature in Samutprakarn.
