I read the article “Simulador PAC: lecciones del análisis del pago verde” and I am pleased to note a positive change in agricultural policy that supports environment-friendly solutions. Based on my experience I have to say that good policy requires equally good tools to apply it in practice. Such a tool is a model that should work in feedback mode in order to react to negative changes in a timely manner. I review literature on models but I have not found a good one so far. During work on the strategy for Ukrainian agriculture I have had to develop theory and practical tools that until present have not been applied. My views on the strategy are accessible in manuscript “The food system …”posted on RG. Obviously, the main question lay in building model technically. Because I am in the end of my professional carrier I am eager to pass my experiences to successors.

The best regards
