Abstract
Background: Forests provide a wide range of water-related ecosystem services (WES) vital for human well-being such as groundwater recharge, runoff and water discharge to streams, soil erosion protection, aesthetic landscape and recreational opportunities. Sustainable forest management and afforestation/reforestation practices can maintain and improve the long-term provision of WES. In this context, new market-based mechanisms – Payments for Ecosystem Services (PES) – can promote sustainable forest management by reducing negative externalities. To implement PES schemes for WES, many stakeholders with different knowledge, interests, and needs must be consulted and involved in the design and implementation process.Methods: The aim of this study is to investigate stakeholders’ opinions on the relationships between forests and water resources and the water-related Payments for Ecosystem Services (PES) schemes in Italy. A semi-structured questionnaire was administered by email to 39 stakeholders identified through a stakeholder analysis. The stakeholders were classified in four groups: buyers (15.4% of stakeholders), sellers (15.4%), intermediaries (43.6%), and knowledge providers (25.6%).Results and conclusions: The results show that the three most important WES provided by forests are soil erosion reduction, followed by provision of habitats for different species and surface runoff reduction. The respondents emphasize the importance of regulating and supporting services, while they minimize the importance of cultural services. For the sample of respondents, market-based instruments have an efficiency comparable to regulatory instruments, but a shared value for ecosystem services among stakeholders is required in the implementation of PES schemes. According to respondents' opinions, the public authority should play the role of both buyer and regulator, while the other stakeholders should be consulted (citizens) or actively involved (farmers’ and forest owners’ associations) in the decision-making process related to the PES schemes.
