AUS-AIF-AGR-GUL General Moderate confidence

Benchmark Value

0 m/ha

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

This body of evidence points to a theoretical ideal for Gully Density in a landscape demonstrating the highest possible environmental health: 0 m/ha of active gullies.

Metric Definition:

Density of active gullies (those with bare, eroding head-cuts or banks) in a landscape under best-practice sustainable or regenerative management.

Benchmark Definition:

This benchmark represents the ideal density of active gullies in an agricultural crop production landscape within the Arid Inland Floodplains & Ephemeral River Systems biome, indicating the highest possible environmental health with no active erosion.

Justification:

This value is derived from the explicit goal of best-practice sustainable or regenerative management systems to prevent new erosion and stabilize existing features, as documented in government guides and regenerative agriculture case studies.

Notes

No upper detrimental threshold — higher values indicate degradation. Active gullies show recent erosion signs; stabilized gullies do not contribute to the density value. AssessmentContext defaulted to 'Not Stated' because the source document did not state one.
