Global trade of biomass-related products is growing exponentially, resulting in increasing ‘teleconnections’ between producing and consuming regions. Sustainable management of the earth's 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 Austria's 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 Austria's physical trade balance in terms of eHANPP. Austria's 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 nation's biomass metabolism.

国家生物质生产和消费的全球影响：2000年奥地利实施的与农业生物质有关的HANPP


生物质相关产品的全球贸易呈指数增长，导致生产地区和消费地区之间的“远程联系”不断增加。地球土地的可持续管理需要指标来监测这些跨区域和规模的联系。 “人类对 NPP 的具体占有”（eHANPP）允许人们一致地将生产链产生的 HANPP 归因于消费者。 HANPP 是土地利用引起的 NPP 变化和生物量收获的总和。我们根据双边贸易矩阵的计算，首次对与农业相关的 HANPP 进行了国家级评估。该数据集允许 (1) 追踪 2000 年奥地利消耗的生物质产品的原产国并量化生产中造成的 HANPP，以及 (2) 将奥地利领土上的国家级 HANPP 分配给全国范围内产品的消费者。该数据集是沿着社会和生态系统之间一致的系统边界构建的，可用于评估奥地利在 eHANPP 方面的实物贸易平衡。奥地利的 eHANPP 贸易平衡略有负值（进口大于出口）；与国家 HANPP 相比，进出口流量很大。我们的研究结果展示了如何使用 eHANPP 方法来量化和绘制与一个国家的生物量代谢相关的遥相关。
