In this interview, I speak to Zach Weiss, who runs a business called Elemental Ecosystems. I met Zach a few weeks ago when I took his workshop, where he taught some of his methods for understanding and managing water in the landscape.

Zach works under the assumption that the core reason for many environmental problems is a misunderstanding and poor management of water. By building dams, repairing eroded stream banks and many other tactics, Zach helps people improve their land’s ability to catch and hold water. This has flow-on effects for local climate, drought resilience and financial stability.
