Identifying Thresholds of Potential Concern (TPC)
The Avon River Basin's top seven resource issues were identified using a resilience assessment based on their capacity to impact upon values, derived benefits, goods and services, and a sense-of-place.
Development of these big issues is usually controlled by a fast or slow moving ‘controlling variable’, or ‘system indicator’. The 'threshold' of each controlling variable indicates a major tipping point where the resource issue fundamentally changes state.
The 'NRM Dashboard' identifies the ARB system's big drivers and aims to determine whether they are moving towards or away from the threshold. It also seeks to establish appropriate points of intervention.
It should be noted that individual resource issues do not function in isolation, but as part of a complex interlinked system.
