Zach Weiss has seen land so degraded that even weeds couldn't grow...and helped transform it into healthy, living landscapes by changing the flow of water and letting nature do most of the work. Protégé of Austrian farmer Sepp Holzer, he works all over the world helping agrarians to restore natural flows on their land, increasing water for crops and livestock, but also for wildlife and downstream water users. The implications for agriculture, wildlife, and climate are huge.
