Assessing the impact of land-cover changes on ecosystem services: A first step toward integrative planning in Bordeaux, France ArchiMer
Cabral, Pedro; Feger, Clement; Levrel, Harold; Chambolle, Melodie; Basque, Damien.
The quantification and integration of ecosystem services (ES) into urban planning decisions is becoming increasingly important. However, studies that quantify and analyze the impacts in terms of ES changes are still scarce. We analyzed multiple ES provided by the landscape of the Urban Community of Bordeaux (CUB), in France, between 1990 and 2006 as a result of land use and cover change (LUCC) with Corine Land Cover and other open data. These ES were selected with the help of local stakeholders and were calculated using a spatially explicit modeling approach with InVEST and own-produced models. It was found that all ES, except erosion regulation, have decreased as a consequence of LUCC. Results also suggest that LUCC change decisions which do not consider...

Ecosystem services assessment and compensation costs for installing seaweed farms ArchiMer
Cabral, Pedro; Levrel, Harold; Viard, F.; Frangoudes, Katia; Girard, Sophie; Scemama, Pierre.
In a global context of promotion and expansion of blue growth initiatives, the development of activities such as aquaculture calls for the assessment of the potential impacts on biodiversity at different levels and associated services. This paper presents an assessment of the potential impact of the installation of seaweed farms on ecosystem services and the induced compensation costs. Biophysical and socioeconomic indicators have been developed for helping decision makers to select the most suitable locations. The approach considers a multi-criteria approach based on Geographical Information Systems (GIS) and Habitat Equivalency Analysis (HEA). The former is used to obtain biophysical ecosystem services and socioeconomic indicators and the latter to...

Marine Ecosystem Services Assessment to Support Marine Management, from Theory to Practice ArchiMer
Vaschalde, D; Bailly, Denis; Cabral, Pedro; Charles, M; Daures, Fabienne; Davoult, D; Dedieu, K; Foucher, Eric; Guyader, Olivier; Laurans, Martial; Le Mao, Patrick; Le Niliot, P; Levrel, Harold; Martin, Jean Christophe; Marzin, Anahita; Mongruel, Remi; Morisseau, F; Schoenn, Jennifer; Thiebaut, E; Vanhoutte Brunier, Alice.
While economic valuation of ecosystem services (ES) is widely acknowledged as a tool to support decision-making processes, studies have also shown that there exists a literature blindspot on the effective use of economic valuation (Laurans et al. 2013; Marco ne and Mongruel 2014). The VALMER project seeks to bridge this gap between theory and practice by looking at how ecosystem services assessment (ESA) can support marine management and planning. Natural scientists, economists and marine environment managers from various institutions undertook ESAs in six pilot sites over the two sides of the Channel. The objectives of this paper are to share some results of two French ESAs, and to discuss issues and perspectives of ESAs from a marine management...
