In the very interesting report mentioned in the previous post, the authors include not only very thorough and complex results but have also found a very illustrative and synthetic way to present them.
The following dependency wheel shows the Direct Material Input of Bangalore in 2001. On the left, is shown the amount and percentage of materials (BM = Biomass, CF = Chemical and Fertilizes, FF = Fossil Fuels, MM = Metallic Minerals, NM = Nonmetallic minerals, O = Others) used by Bangalore. On the right are represented the economic sectors (SO1 = Agricultural and mining, SO2 = Biomass-related products, SO3 = Chemical and fuel products, SO4 = Construction products, SO5 = Metallic products, SO6 = Machinery and equipment, SO7 = Utilities, SO8 = Construction, SO9 = Services, SEXP = Exports, SFC = Final Consumption, SGFCF = Gross fixed capital formation) and how much material input they use. Finally, the dependency wheel shows how different materials are used by different economic activities/sectors.
For instance in red, it is possible to see that 40% of the Biomass input of Bangalore is used by the Biomass-related products, 10% is used by the Services, and approximately 40% is used in Final Consumption.
