Science Friday: The Avenue Of The Baobabs | This tiny region in the Sahara supplies half of the nutrients for the Amazon

The Avenue Of The Baobabs

    The Avenue or Alley of the Baobabs is a prominent group of baobab trees lining the dirt road between Morondava and Belon’i Tsiribihina in the Menabe region in western Madagascar. Its striking landscape draws travelers from around the world, making it one of the most visited locations in the region. It has been a center of local conservation efforts, and was granted temporary protected status in July 2007 by the Ministry of Environment, Water and Forests, the first step toward making it Madagascar’s first natural monument.

Today in Astonishment: The Amazon Rainforest Gets Half Its Nutrients From a Single, Tiny Spot in the Sahara

    The Amazon basin is one of the world's wondrous ecosystems, supporting massive amounts of life, both in kind and quantity. You might have thought about poison frogs or monkeys, but you've probably never stopped to wonder, "Where are all the nutrients that power this biotic explosion coming from?"

    The answer is actually astonishing and delightful in that one-planet-one-love kind of way. As laid out in a 2006 paper that science writer Colin Schultz dug up, nearly half of the nutrients that power the Amazon come from a valley in the Sahara called the Bodélé depression. At 17,100 square miles, the area is about a third of the size of Florida or 0.5 percent the size of the Amazon basin it supplies.

    "This depression is a unique dust source due to its location at a bottle neck of two large magmatic formations that serves as a `wind lens', guiding and focusing the surface winds to the Bodélé," the authors, an international team of geologists, wrote.
