This conference debat will take place at the EHESS (Amphithéâtre) from 2:30 p.m. to 5:30 p.m.

The Millenium Ecosystem Assessment (MA) gave legitimacy to the concept of ecosystem services, which helps capturing the complex relationships between nature and societies.
The German Federal Ministry for the Environment and the European Commission, with the support of several other partners, jointly initiated a global study called “The Economics of Ecosystems & Biodiversity” (TEEB).
Mr Pavan Sukhdev was appointed as the independent Study Leader, assisted in his task by an Advisory Board consisting of prominent experts.
The study evaluates the costs of the loss of biodiversity and the associated decline in ecosystem services worldwide, and compares them with the costs of effective conservation and sustainable use.

Speaker :
Pavan Sukhdev will present the TEEB process and introduce preliminary results as well as challenges ahead.

Panellists :
* Michel Trommetter will discuss the scientific robustness of TEEB and point out specific issues and challenges associated with intellectual property rights.

* Claude Henry will draw lessons from a comparison between the TEEB process and the Stern Review from which it was inspired.

* Laurent Mermet will discuss the use that stakeholders (may) make of economic valuations of biodiversity in decision making and negotiation processes.
