Biomimicry, I like the word
Personal Notes : Greening the desert seamlessly is the way to go. I have already covered the Sahara Forest Project, and its concepts, they are pretty much the core of Project Genesis, allowing for the sustainable colonization and exploitation of world deserts. One should not imagine massive industries pumping water deep in the desert but a seamless underground network that achieves the same while not being visible, leaving to the desert a maximum of its sanctity and beauty. That network come to think of it can also act as massive water dispersers thus irrigating the area around them and forming green corridors deep into the desert. Roman times are not that far geologically speaking...
"In Roman times, the deserts of North Africa were fertile, crop-growing regions. There are plans to re-green areas of the Sahara in a project that combines seawater greenhouses and concentrated solar power. In the Sahara Forest Project, in Jordan and Qatar, seawater greenhouses will harness fresh water through condensation; a technique used by Namibian fog-basking beetles. Biomimicry, it seems, offers us a greener future."
