He is the author at acts Sud of: “the trees between visible and invisible”. One hour with him and you will never look at a tree the same way again.

The French School of Agroforestry

Fertile agriculture “from soil to landscape”… Our countryside and our farmers really need it. Agroforestry is developing today to respond to this vast collective project, at its own pace. Like a tree which, from the seedling, puts in place each of its branches, its roots, its leaves...
