Developed at the University of Lisbon, Portugal, The NativeScapeGR project focuses on uses native plant species and biocrusts to create green roofs with low water requirements, adapted to Mediterranean-type climates. Although green roofs have countless environmental benefits, they’re rare in most Mediterranean areas, mainly because of installation and maintenance costs, including irrigation. Green roofs that use native plants would maximize water use and sustainability in that region, while also enhancing biodiversity. Biocrusts are consortia of cyanobacteria, fungi, and lichens that can grow in extreme low water conditions. Since they can shut down their metabolism during dry spells, they can survive for months or even years with low water intake, while still providing the homes beneath them with the benefits of a living roof.
