Very interesting article, that rightly points to the fact that economic valuations of the environment itself (and ecosystem services) are maybe not the key argument for combating environmental degradations. A first step should be to argue against some projects based on their own assumed economic rationale, taking stock of the fact that quite often these projects are decided on other grounds than purely economics. Major political decisions on infrastructure or other sectors impacting on the environment are not based on sound economic analysis. So considering ecosystem services in the economic analysis are a kind a cherry on the cake.
