Ecological footprint has been used to describe the amount of resources used by the human population. However, this is difficult to monitor and calculate. Starting from the opposite end of the spectrum, we begin with existing regions, towns and villages and then determine the optimum land base based on the existing population and area already taken up. This makes it easier to calculate the resources that could potentially be allocated to that region. Local knowledge of the area can take this general estimate and turn it into something more workable.
This image shows calculated resource usage based on population. The model calls for target food production (and potentially other types of production) to occur within about ten miles (15 kilometres) of the city. This is colored in a darker green. Beyond that (up to about the twenty five mile radius) there would be additional existing production. This is colored in a lighter green. The city is colored in light grey.
The base for an interactive map has been developed. It shows the same information depicted above, but is "live" in the sense that it shows a map that the user can interact with. [More...]
