Figure 2.1: Components of the ecological footprint and Ecological Balance of Trade

Text description of figure

The regional economy consists of inputs from:

• Agricultural land
• Forest land
• Degraded land
• Energy land
• Imports from other regions (which have agricultural, forest, degraded and energy land embodied in them)
• Imports from other nations (which have agricultural, forest, degraded and energy land embodied in them)

and outputs of

• Exports to other regions
• Exports to other nations
• Agricultural, forestry, fish, mining, manufacturing, services and other products to households within the region.

The ecological footprint is worked out by adding up the indirect inputs to households within the region from the regional economy:

• Agricultural products
• Forestry products
• Fish
• Mining products
• Manufacturing products
• Services products
• Other

and then adding the direct inputs to households within the region

• Imports from overseas
• Direct land occupied by households
• CO2 emissions
• Imports from other regions.

The ecological balance of trade is worked out by adding up:

• Exports from the regional economy to other regions
• Exports from the regional economy to other nations

and then subtracting the total of:

• Imports to the regional economy from other regions
• Imports to the regional economy from other nations
• Imports to households within the region from overseas
• Imports to households within the region from other regions.
