A proposal for defining the geographical boundaries of Amazonia

A group of European experts came together for a two day workshop at the Joint Research Centre, Ispra, to discuss a proposal for defining the geographical boundaries of Amazonia. The experts represented a wide range of scientific disciplines from climate studies to phytogeography. A consensus approach was taken to developing a concept.
