Analisi delle relazioni fra la sostenibilità del ciclo dell'acqua e il sistema economico

It is well known that the water cycle is going to assume a central role in the economic system because of its increasing relative shortage. This means that even though the water available to planet Earth is the same water that has always been available and the only water that ever will be available, in reality however, we have a limited amount of usable drinking water. Since the drinking water conservation and its production depends on the economic activity, in this paper we analyse the link between water cycle and the economic system constructing a new type or framework that combines standard material of account (MFA) techniques with make and use (M&U) accounting matrices in order to coordinate the physical issues of accounting to the value issues. The impact of economic policies on the water cycles as well as consistency of policies with sustainability is then evaluated showing the importance of the natural resourceseconomic system feedback in this kind of analysis. In other terms, this new framework allows the analyst to consider both the effect of given policies on the water cycle and the constraint produced by the sustainability problem on the economic system. Finally, we studied the dynamical system resulting from the MFA and M&U integration and show how to investigate the estimation problem of the framework extrapolating the use by use matrices from the system.
