He is more commonly known as Max Puig, and is part of the APD - Alianza por la Democracia, a small independent political party that broke away from the PLD a few years ago. The APD lend their support to the PLD at election times and in return their leading figures receive appointments in the new administration. In the 96-00 PLD government he was in charge of the EU/Lome development fund, and appeared to do a good job.
Max is always very knowledgeable and articulate about national and international issues, but I have never seen him discuss the environment in depth.
I don't know what the new government will do in practice, but in principle they have been critical of the previous administration's actions on the Parque Nacional del Este issue.
