Netics, Witteveen+Bos win Global Disruptive Tech Challenge May 3, 2021, by Eldin Ganic Netics and Witteveen+Bos have won the Global Disruptive Tech Challenge 2021 for landscape restoration in the Aral Sea region of Central Asia. With Netics’ patented ‘Geowall land cultivation technology’, the two Dutch companies won in the category Agriculture and Land Management. The winning entry from Netics and Witteveen+Bos envisages the use of sediment dredged from a part of the Aral Sea. This sediment is mixed with soil and applied in the dried up part to cultivate the landscape and stop desertification. The entry by Netics and Witteveen+Bos builds on the Geowall concept developed to reuse sediment.
