Evidence & Context

regional data from non-urban landscapes suggests a density > 1 m/ha indicates significant degradation

Metric Definition:

Gully Density, defined as the density of active gullies in the landscape.

Benchmark Definition:

A gully density greater than 1 m/ha indicates significant landscape degradation based on regional data from non-urban areas.

Justification:

This value provides a practical scale of management failure based on regional data from non-urban landscapes.
