Abstract

Ecosystems provide a varied range of services to people known as ecosystem services (ES) which contributepositively to human well-being. Thus, their quantification and integration into planning decisions has become increasingly important.In this study we analyzed ES provided by the landscape of the Urban Community of Bordeaux (CUB) in France. These ES were selected using a participatory approach with local stakeholders and involved the creation of scenarios of land use and cover change (LUCC) expressing alternative planning
options. Only open data was used. Results show that allthe analyzed ES, except erosionregulation, have decreased as a consequence of LUCC between 1990 and 2006. For year 2030, the "Plan" scenario, which integrates approved urban local plans, is the one that will cause more negative impacts on the CUB ES. Both "Conservation" scenarios present a more balanced situation allowing to choose between carbon storage improvement or agriculture preservation with a degradation on nitrogen and phosphorous retention ES. We also found that there is little or no tradeoff on nutrient and sediment retention services regardless of the scenario used.
This spatial explicit approach to ES modeling enables an informed discussion with the stakeholders about different planning options and their impact on ES and tradeoffs. Additionally, it may be used to effectively implement, monitor and communicate planning policies.
