Project Description

Arid landscapes that have lost their topsoil are subjected to erosive forces of wind and water to form a clay crust that prevents the growth of vegetation. Ray Thompson explains the technique of waterponding, which captures and directs water, slowing runoff and creating an environment for vegetation to reestablish. In the long-term wind erosion is prevented and the land becomes arable pastureland. The techniques is gaining widespread adoption in arid Australia and overseas.
