Direction: Lower is desirable ↓
Form: Point

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

Based on these convergent lines of evidence, the only scientifically defensible benchmark for the density of active, eroding gullies in a landscape representing the best available condition under regenerative cropping is 0 m/ha.

Metric Definition:

Gully Density is the total length of active gullies per unit of land area.

Benchmark Definition:

This benchmark represents the ideal condition of zero active, eroding gullies per hectare in agricultural crop production landscapes within Australia's arid mountain ranges and uplands, indicating minimal soil erosion under regenerative cropping practices.

Justification:

Active gullies indicate severe landscape degradation; thus, maintaining zero gully density is critical for soil conservation and sustainable regenerative cropping.

Notes

No upper detrimental threshold — higher values are always worse, indicating increasing gully erosion. The optimal range is exactly 0 m/ha, reflecting the absence of active gullies as the target condition. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
