When are payment for ecosystems services suitable for coral reef derived coastal protection?: A review of scientific requirements

Abstract : Payment for Ecosystem Services (PES) is an emerging tool intended to solve a range of ecosystem management inefficiencies, by linking conservation action to payment. Such schemes have not been tested to our knowledge, for coral reef derived coastal protection, which is a key Ecosystem Service (ES) for many nations bordered by tropical coral reefs. Coral health is deteriorating globally, as are their ES and inadequate finance is identified as a cross cutting factor stymieing management action. In this paper, we assessed the feasibility of PES for coastal protection, with a focus on the scientific requirements. Key PES elements related solely to ecological processes were isolated, the role of coral reefs in protecting beaches reviewed and priority management options for improving reef health synthesized. Outputs indicate that there is adequate scientific knowledge to satisfy a PES. While there is limited ability to prove and quantify causality between management actions and ES delivery, PES criteria can be satisfied with the substitution of a management proxy, rather than payments being conditional on ES measurements. Management, both passive and active, would focus on aintaining reefs that already have a protective function and front stable beaches, above a functioning threshold.
