Identificatie van belanghebbenden en evaluatie van PES-‘achtige’ instrumenten in Vlaanderen

Over the past decade there has been a substantial increase in the use of market based and voluntary financial instruments to address environmental issues. By using price signals or incentives, these instruments try to achieve desirable land use practices and resource management. In recent years PES (Payment for Ecosystem Services) emerged as such an instrument with high potential. Roughly speaking, PES aims to issue compensations for extra cost induced to ecosystem owners and managers (e.g. farmers, water companies, etc.) for maintaining a stable or increased supply of ecosystem services. Although this seems a quite straightforward approach, much confusion arose about what PES really is, and what it is not. We explore why it is important to come to a single definition of PES for Flanders (Belgium) and identify in which setting PES would be an efficient and desirable alternative to current policy instruments. Additionally we compiled a series of 20 key success factors and conditions for PES instruments based on a thorough review of international (practical) experiences and state of the art literature. Based on these success factors, we critically examined and evaluated a series of financial, “PES-like”, instruments currently used in Flanders (e.g. agri-environment measures). For that purpose 3 case studies were conducted in the areas of Gent (Gentse Kanaalzone), Leuven (Doode Bemde) and Sint-Truiden (Melsterbeek) and focussed on a series of financial instruments (mainly subsidies) and how they affect ecosystem services and stakeholders. This research project resulted in a guideline for the identification of ESD stakeholders and an opportunity analysis to manage and enhance additional ecosystem services with current financial instruments. We concluded that some existing financial instruments show great potential to mainstream a PES approach, which could greatly improve their ecosystem service output. Also participation to voluntary financial instruments can be substantially increased with a better understanding of the links, in terms of ecosystem services, between stakeholders and land use practices promoted by voluntary financial instruments.
