Distinguishing regeneration from degradation in coral ecosystems: the role of value

In this paper I argue that the value attributed to coral reefs drives the characterisation of evidence for their regeneration or degradation. I observe that regeneration and degradation depend on an understanding of what an ecosystem looks like when undegraded (a baseline), and that many mutually exclusive baselines can be given for any single case. Consequently, facts about ecological processes are insufficient to usefully and non-arbitrarily characterise changes to ecosystems. By examining how baselines and the value of reefs interact in coral and algal reef examples, I argue that considering the value of an ecosystem is a necessity when describing processes like regeneration and degradation. This connects value as studied in socio-ecological and economic research with values as discussed in the philosophy of science literature. It also explains why such a broad range of processes may be considered regenerative, including those which introduce significant novelty, as well as pointing towards ways to mediate related debates, such as those surrounding novel and 'pristine' ecosystems.

Automated summary

The value attributed to coral reefs greatly influences the characterization of evidence for their regeneration or degradation, highlighting the necessity of considering the value of an ecosystem in describing processes like regeneration and degradation. This also connects value as studied in socio-ecological and economic research with values as discussed in the philosophy of science literature.
