Evidence & Context

Based on a synthesis of these constraints and objectives, a scientifically defensible benchmark for a "best-on-offer" sustainable cropping system in Australia's Arid Inland Floodplains is a Basal Area in the range of 5 to 10 m²/ha.

Metric Definition:

Basal Area is defined as the cross-sectional area of tree stems per unit of ground area, typically expressed in square metres per hectare (m²/ha).

Benchmark Definition:

This benchmark defines the optimal basal area range of 5 to 10 m²/ha for sustainable cropping systems in Australia's Arid Inland Floodplains, balancing ecological health and agricultural productivity.

Justification:

This benchmark is derived by synthesizing evidence for functional thresholds balancing ecological health and agricultural viability.
