For a study commissioned by the German Environment Agency and conducted in collaboration with the Vienna University of Economics and Business and the Ecologic institute, the IIASA LANDFLOW model was extended. This involved the development of a hybrid accounting method for the model and integration of land quality, extended resource use (water, nutrients, and energy), and environmental impacts, such as deforestation . This approach for land flow accounting combines elements from both physical and environmental-economic accounting.
The extended model was applied for the years 1995-2010, encompassing 21 markets globally, including Germany as a separate market . The results revealed increasing areas of cropland needed for agricultural products that are produced in one country but consumed in another.
At the global level, the share of cropland appropriated for the non-food products increased from 8.6% in 1995 to 12% in 2010. This highlights the importance of accounting for such products when striving for sustainable development.
This footprint analysis provides key information required for finding solutions to global challenges at the land-water-food-energy-environment nexus.
