Payments for Ecosystem Services (PES) schemes are increasingly promoted to protect ecosystems and their associated services. However, there is a challenge to contextualising these schemes, which are often site-based, within the broader biophysical landscape. Notably, PES schemes are subject to a range of local and global processes and stressors. Stressors external to a PES site, such as forest fires, pollution, sea level rise, and ocean acidification, may undermine ecosystem stability and sustained ecosystem service provision, yet their threats and impacts are difficult to account for within PES scheme design. During this talk, I will present a typology of external biophysical stressors, and consider their implications for environmental governance and PES.
