Work Package 4 (WP4) is in charge of implementing the methodological framework on the case studies both in France and in Québec. Those two case studies have been chosen because of their very contrasting portraits and because in both of them, a significant part of the economy relies on different ecosystem services that may be affected by other economic activities, highlighting the need of a framework such as the one developed in the current project to transparently and strategically analyse the situation and identify the best future avenues for the common good.
