Integrating payment for ecosystem services in protected areas governance: The case of the Po Delta Park

The effective inclusion of Ecosystem Services (ES) in the governance of Protected Areas (PAs) is a key challenge for future environmental governance. In this sense, Payments for Ecosystem Services (PES) have been conceived as instruments to internalize costs of environmental management and establish a consequential link between ES users and providers. Thus, while there is a current pressingly need for genuine PES mechanisms, in very rare cases it has been possible to satisfy this requirement. This paves the way for the study of alternative methods, such as PES-like schemes, which may be already in practice in PAs. In order to support and discuss the feasibility of this approach, we present four successful PES-like schemes currently working in the Po River delta Park of the Emilia-Romagna region (Northern Italy). They involve traditional activities, as hunting, fishing, mushroom and truffle (M&T) picking and cultural services, coherent with the UNESCO Man and Biosphere declaration. With the aim of using the peculiar case of the Po Delta Park as a study model, we studied services with direct market value that cover a variety of strategy cases and positive side effects typically observed in genuine PES schemes. The Park authority is a crucial actor with different roles: i) regulator/intermediator in the context of a "command" strategy (for hunting and M&T) and in a public–private partnership (for cultural services) and ii) provider in a trade context (for fishing). Although not originally conceived under the vision of an ES approach, these practices, developed as endogenous processes, were effective in supporting conservation and ES provision. While not accounting for regulating services, PES-like schemes constitute practical evidence of broad interest concerning the role of existing, yet overlooked, mechanisms involving important ES, which could be reframed within the terminology of PES to strengthen their functioning and strategic value.
