If you want to read more about the specific indicators/requirements regarding this topic [Criterion 2.8: Minimising salinisation of soil and groundwater] and other information relating to the ‘Alignment’ and draft ASC Farm Standard (including specific questions part of the Stakeholder Survey), please click here.
These issues are also currently addressed within the existing ASC species Standards: all of ASC’s 11-species Standards can be found here.
Why is this an issue?
Salinisation is the result of an increase of salt concentration in soil and freshwater (both surface and groundwater) due to natural causes or human activities. As a result of this, biodiversity can be impacted and these natural resources can also become less suitable (or even fully unsuitable) for use in aquaculture.
Known examples of salinisation in aquaculture are caused by infiltration from saline waterbodies (e.g. ponds), discharge of saline water into fresh surface water, or (over) use of freshwater wells resulting in (more) saline water intrusion into groundwater. The last example is particularly relevant for regions near coastlines and can be further amplified in case of sea-level rising and land subsidence.
This is why the proposed ASC Farm Standard aims to ensure that risks of salinisation of soil and freshwater resources are minimised as a result of the farms’ activities.
