Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

Therefore, the reference value for Active Gully Density is a state approaching 0 m/ha.

Metric Definition:

Active Gully Density representing the length of actively eroding channels per unit area.

Benchmark Definition:

Active Gully Density measures the length of actively eroding channels per unit area. In this biome and land use, the benchmark represents a stable landscape with minimal active erosion, ideally approaching zero active gullies per hectare.

Justification:

The benchmark is derived by triangulating multiple lines of evidence including erosion rate reduction, landscape-scale observations, gully remediation efficacy, and principles of regenerative agriculture.
