My Google Alert inbox this morning let me know that Michel Serres has contributed to a UNESCO book titled "Making Peace with the Earth" (Berghahn Books/UNESCO Publishing). I wasn't familiar with the series but apparently it is the third volume in the UNESCO 21st Century Talks which is edited by Jérôme Bindé. The article from a Turkish source states that Paul Crutzen, Nicolas Hulot, Javier Pérez de Cuellar, Michel Serres, Mostafa Tolba, Asit K. Biswas and Edward O. Wilson are among the contributors. A quick spin around the UNESCO site didn't turn anything up on the book. I'll check back later.
