Evidence & Context

Indicative EC Values: Central/Southern Zone: 3,000 – 9,300 00μS/cm

Metric Definition:

Water electrical conductivity (EC)

Benchmark Definition:

In the Central/Southern Zone of the Arid Karstic Woodlands & Shrublands, water electrical conductivity between 3,000 and 9,300 µS/cm indicates a system under active pastoral use with low ecological impact and sustainable function.

Justification:

Water quality is suitable for productive pastoralism without causing significant land degradation.
