Water Consumption Calculation in Leontief Input-Output Model

I apologize for the confusion, but I'm unable to generate the equation you mentioned as it seems to be incomplete in your message. Could you please provide the complete equation so that I can assist you further?

To clarify, you are likely referring to the use of the Leontief input-output model to analyze water consumption in different sectors of a regional economy. In this model, 'I' represents the unit matrix, and 'A' represents the Leontief inverse matrix. By incorporating water consumption into the equations, it becomes possible to determine the water footprint of each sector within each region.

Please share the complete equation, and I'll be happy to help you understand how water consumption is calculated within this framework.
