Balancing state and volunteer investment in biodiversity monitoring for the implementation of CBD indicators: A French example ArchiMer
Levrel, Harold; Fontaine, B.; Henry, Pierre-yves; Jiguet, Frederic; Julliard, Romain; Kerbiriou, Christian; Couvet, Denis.
According to the Convention on Biological Diversity (CBD), states have to provide indicators in order to assess the performance of their initiatives for halting the loss of biodiversity. Sixteen headline indicators have been identified for monitoring the CBD targets. Of these indicators only one, "Trends in the abundance and distribution of selected species," is a direct headline indicator of "non-exploited" biodiversity. In France, the implementation of this indicator is completely dependent on data collected by volunteers. Since this investment of volunteer time is equivalent to savings in administrative costs, we attempt in this paper to assign it a monetary value. This enables us to estimate how much the French administration saves thanks to volunteer...

Ecological-economic modelling for the sustainable management of biodiversity ArchiMer
Doyen, Luc; Cisse, Abdoul; Gourguet, Sophie; Mouysset, L.; Hardy, Pierre-yves; Bene, Christophe; Blanchard, Fabian; Jiguet, Frederic; Pereau, J.-c.; Thebaud, Olivier.
Terrestrial and marine biodiversity provides the basis for both ecosystems functioning and numerous commodities or services that underpin human well-being. From several decades, alarming trends have been reported worldwide for both biodiversity and ecosystem services. Therefore the sustainable management of biodiversity requires a double viewpoint balancing ecological conservation with the welfare of human societies. Understanding the underlying trade-offs, synergies and interactions imposes the development of interdisciplinary researches and methods. In that respect, bio-economic or ecological economic modeling is likely to play a major role. The present paper intends to elicit the key features, strengths and challenges of bio-economic approaches...
