The free energy of an ecosystem: towards a measure of its inner value

Based on a free energy approach, we propose the estimation of ecosystem Inner Value, which is both non-instrumental and objective, reflecting the ecosystem’s value for itself as a natural entity, abstracted from any human valuation activity. The ecosystem services approach has become the dominant criteria for studying the relationship between humans and nature. Although there is concern about preserving and recuperating damaged ecosystems, we seldom consider how much the ecosystem values itself. Then, we propose that Inner Value could be a tool to evaluate and model ecosystems’ health before any anthropic disturbance, allowing comparison with the impact these disturbances may have in the future. We also suggest that it should be a requirement for any Environmental Impact Assessment. Significance Statement Ecosystem are valued for the services they provide to human. Therefore, they are estimated following human (mostly economic) criteria. However, any ecosystem has its own value independent of the services it can give. Therefore, we propose the use of the Inner Value concept as a non-instrumental, objective measure reflecting the ecosystem’s value for itself as a natural entity based on a free-energy approach. Inner Value could be a tool to evaluate and model ecosystems’ health before any anthropic disturbance, allowing comparison with the impact these disturbances may have in the future.
