Global effects of national biomass production and consumption: Austriaʹs embodied HANPP related to agricultural biomass in the year 2000

Global trade of biomass-related products is growing exponentially, resulting in increasing ‘teleconnections’ between producing and consuming regions. Sustainable management of the earthʹs lands requires indicators to monitor these connections across regions and scales. The ‘embodied human appropriation of NPP’ (eHANPP) allows one to consistently attribute the HANPP resulting from production chains to consumers. HANPP is the sum of land-use induced NPP changes and biomass harvest. We present the first national-level assessment of embodied HANPP related to agriculture based on a calculation using bilateral trade matrices. The dataset allows (1) the tracing of the biomass-based products consumed in Austria in the year 2000 to their countries of origin and quantifying the HANPP caused in production, and (2) the assigning of the national-level HANPP on Austriaʹs territory to the consumers of the products on the national level. The dataset is constructed along a consistent system boundary between society and ecosystems and can be used to assess Austriaʹs physical trade balance in terms of eHANPP. Austriaʹs eHANPP-trade balance is slightly negative (imports are larger than exports); import and export flows are large in relation to national HANPP. Our findings show how the eHANPP approach can be used for quantifying and mapping the teleconnections related to a nationʹs biomass metabolism.
