Pablo Jensen and company have announced a new Michel Serres Institute for Resources and Public Good that will likely be of interest to readers of Serres. You can read more about it here but I've included a brief excerpt for you:
Humans use their power and knowledge to manage life systems as well as the biosphere. Therefore, research must serve to increase human understanding of those resources and how best to use them for the public good. The Institute will work towards the desired, sustainable condition of our societies through the integrated analysis, monitoring and management of resources (production, distribution, access and circulation)
No doubt the themes in The Natural Contract and many other works will have a bearing on how the activities and writing of the institute unfold over time. This is about all I know of it at this point but if others can contribute background, that would be helpful. I have been in touch with Pablo and hope to add more information here soon.
