The Valley of Giants by Eric Randall Morris, Galo Canizares United States.
Located north of Tindouf, Algeria, the Valley of Giants is the largest oasis in Northern Africa. As global conflicts grew and their impact rippled over several continents, demand for refugee housing and temporary settlements increased in the area. They needed something that addressed the influx of immigrants, the desertification of the area, and changing cultural diversity; something beyond a quick-fix.
The concept was simple: A series of towers that would (1) house plant-spores, (2) produce, collect, and treat water, and (3) pollinate the surrounding landscape, catalyzing the production of an oasis in the region. The structures themselves had to be of an immense scale in order to effect significant change; so they were designed as 1km (.6 mile) tall, thin, cylinders. A network of underground pipes facilitates the creation of pools and wells.
Within 20 years, the area would drastically transform from a barren landscape into the Valley of the Giants. Today it is home to both permanent residents and traveling nomads.
