HANPP Collection: Human Appropriation of Net Primary Productivity (HANPP) by Country and Product

The HANPP Collection: Human Appropriation of Net Primary Productivity (HANPP) by Country and Product contains tabular data on carbon-equivalents of consumption by country and by type of product. The data were compiled from national-level FAO statistics on consumption of products such as vegetables, meat, paper, and wood. HANPP represents the amount of carbon required to derive food and fibre products consumed by humans including organic matter that is lost during harvesting and processing. Net primary productivity (NPP), the net amount of solar energy converted to plant organic matter through photosynthesis, can be measured in Units of elemental carbon and represents the primary food energy source for the world's ecosystems. These tabular data were used to allocate country level NPP consumption to a spatial surface of NPP consumption (Global Patterns in Human Appropriation of Net Primary Productivity), which is part of this collection.

《HANPP 数据集》：国家及产品层面的人为净初级生产力（HANPP）利用，该数据集包含关于各国及各类产品消费碳当量的表格数据。数据来源于各国层面的联合国粮食及农业组织（FAO）关于蔬菜、肉类、纸张和木材等产品消费的统计数据。HANPP 反映了用于生产人类消费的食物和纤维产品所需的碳量，包括在收获和加工过程中损失的有机物。净初级生产力（NPP）是指通过光合作用将太阳能转化为植物有机物的净量，其单位以元素碳计，代表着世界生态系统的首要食物能量来源。这些表格数据被用于将国家层面的 NPP 消费量分配至 NPP 消费的空间表面（全球人类对净初级生产力利用的模式），该部分构成了本数据集的一部分。
