Adapting farm systems to a drier future

Abstract

In the Starborough-Flaxbourne area the local farming community, alarmed at the increasing hill slope erosion, set up a soil conservation group. Accelerated erosion was a symptom of the past 12 years of below average rainfall. Removal of vegetative cover by livestock had enabled wind to erode areas of the thin topsoil exposing vulnerable sodic subsoil to rill and tunnel erosion. This highlighted the need for farms to adapt their livestock systems to a drier environment if they were to survive.
