Introduction Beyond the intrinsic, aesthetic and spiritual values one may assign to nature, the reasons to manage it are multiple due to its central role in a wide panel of ecological functions crucial to human wellbeing and development. For instance, biological structures and ecological processes provide us food, raw materials, water and energy, protect us against erosion or floods, control water quality, pest impact, pollination, give us large enjoyable spaces for recreation, sport and leisure activities, etc. Despite contributing considerably to economic development, social welfare and health, natural resources have often been considered as inexhaustible and unlimited which has caused dramatic damages in economic, social and environmental issues. This is mainly explained by the fact that many ecosystem services (ES) are ‘public goods’ or ‘common goods’: they are often open access in character and non-rival in their consumption. Market and policy decisions often fail to capture most ES values with the exception of a few marketed provisioning ecosystem services ‘ES’ (e.g. food, timber). This systematic under-valuation of ecosystem services and failure to capture the values is one of the main causes underlying today’s biodiversity crisis1. ES valuations can serve as methodological baseline for decision support tools aiming at more sustainability thus guiding and accelerating transition. To sustainably manage the supply and the demand of ES, the policy level needs to gain knowledge on where and which services are provided2–4and who are the stakeholders involved. ES maps provide an explicit link between the biophysical data of the ecosystem and expectations of main concerned stakeholders2. There are an essential tool to help for more holistic and transparent decision processes .Additionally, ES valuations allow highlighting ES hotspots, bundles and trade-offs and priority areas for action5. At last, ES valuations can serve as policy efficiency barometer by measuring ES before and after a specific measure. The ...
