The Sahara is about the worst place on Earth to find water today, but that wasn’t always the case. Thousands of years ago, its sandy dune fields were lush and verdant. A new scientific paper helps explain why: the Western Sahara used to be irrigated by a vast river network.
French architectural design firms Nicholas Laisné Associés and OXO Architectes have put together a concept for a massive arcology for the Saharan desert. The La Tour des Sables would be a self contained city that rises 1,400 feet above the ground, and would be contain living, agricultural and working units.
When you think ‘Sahara desert’ your mind’s eye probably conjures images of tawny, windswept dunes stretching monotonously into the horizon. But satellites have a way of giving us a strikingly different, often much more interesting view of our world.
Here's an awesome 3D visualization from NASA that shows how the Sahara Desert helps fertilize the Amazon rainforest even though they're on two different continents that are separated by an entire ocean. The Saharan dust is carried over by wind and the phosphorous in the dust is essential to the Amazon.
As conventional sources of clean water dry up, we're looking ever farther, wider, and deeper. In a long feature on unusual sources of water, Nature leads us somewhere especially unexpected—into the middle of a desert. The Sahara Forest Project wants to prove we can green the desert, turning barren land into oases of…
Depending on how you look at this image, it's either a striking view of Western Sahara, or a cartoon mountain, backed by blue sky and shrouded in cloud.
It's undeniable that this satellite image of the Al Jawf oasis in southeastern Libya is incredibly striking, with large irrigated plots standing out in contrast to their barren surroundings. But, a little like staring at clouds, their lay-out is enough to get your imagination running wild.
