At the core of the challenge we face is the inevitable uncertainty of dynamic combination human-natural systems. Rapid modifications of biophysical systems have the potential to trigger regime shifts —abrupt and irreversible changes—that will have significant consequences. It is clear that the likelihood of regime shifts is higher in ecosystems where humans have reduced resilience by modifying biogeochemical cycles, altering hydrological regimes, reducing biodiversity, and changing the magnitude, frequency, and duration of disturbance regimes. We know these are hard problems to solve, but they are by no means impossible. A new understanding of our relationship to the natural and designed…
