What happens when one no longer gets ecosystem services payments?

As programs of payment for ecosystem or environmental services (PES) are rising in number, there is a need to understand effects of PES on providers’ motivations and, in turn, behaviors.  ‘Crowding in’ of pro-environmental motivations is possible − although a significant literature has expressed concern with the ‘crowding out’ of such motivations by external interventions. Yet empirical research is scarce concerning any such ‘crowding’ by PES − in either direction. Theoretical hopes and concerns are clear but, to date, the related empirical evidence is limited.
