Despite being from Vienna, the “birthplace” of MFA, it is safe to say that the authors did not “get” the MFA methodology.  What appear to be flow quantities sit next to the processes, and a mysterious thick line cuts through the system boundary.  I appreciate the attempt to include transport in a MFA diagram, but this sample is more a demonstration of what can go wrong.
