From the Politics of Nature, p246:

The term does not differentiate between scientific ecology and political ecology; it is built on the model of (but in opposition to) “political economy.” It is thus used to designate, by opposition to the “bad” philosophy of ecology, the understanding of ecological crises that no longer uses nature to account for the tasks to be accomplished, it’s used as an umbrella term to account for what succeeds modernism according to the alternative “modernize or ecologize.”

From the Politics of Nature, p4:

Political ecology is said to have to do with “nature in its links with society.” But this nature becomes knowable through the intermediary of the sciences; it has been formed through networks of instruments; it is defined through the interventions of professions, disciplines, and protocols; it is distributed via data bases; it is provided with arguments through the intermediary of learned societies.
