Practical measurements: Water as an ecosystem good
Date of this Version
We started with the proposition that catchments (or river basins) would form ideal national boundaries. Although a river can wind through myriad sub-ecosystems (from mountains, to grasslands, to wetlands), it is the life blood of the system, falling water, running water, underground water and evaporating water, that captures our attention and presents both the opportunities and constraints that define our natural economy. If a catchment (presumably a large one) was a nation, the first thing we would do is construct a comprehensive model of its economy. Our treasury departments, in particular, and our governments in general, could not operate without a very good model of their economy.
