Evidence & Context

Based on this evidence, an infiltration rate of less than 10 mm/hr within a vegetated patch is proposed as the lower critical threshold.

Metric Definition:

Lower critical threshold for soil water infiltration rate within vegetated patches indicating severe degradation and functional collapse of the water-harvesting system.

Benchmark Definition:

This benchmark defines the lower critical threshold for soil water infiltration rate in vegetated patches, below which ecosystem function is impaired due to insufficient infiltration.

Justification:

Indicates severe degradation and functional collapse of the water-harvesting system in vegetated patches.

Notes

Below this value, the patch is likely unable to capture the majority of water from a typical rainfall event, initiating a negative feedback loop of desiccation, vegetation death, further soil structure collapse, and eventual erosion.
