In order to perform a Water Scarcity Footprint (WSF), as per the ISO standard 14,046 (2014), it is necessary to multiply a volume of water consumed in a specific region, with the corresponding local water scarcity indicator. The use of these factors is recommended in priority at the native scale at which these factors were developed, which is the watershed scale. Alternatively, country-scale factors are provided to accommodate practitioners who may not have access to the exact watershed from which the water consumption they are assessing is located. However, such factors come with very large uncertainty. In several cases the practitioner may have access to a higher spatial resolution information, such as a state, province or department within one country. For this reason, the present work proposes sub-national AWARE factors for the entire globe, using sub-national borders, as an in-between resolution of watersheds and countries. Factors are provided for 3428 administrative regions, per month as well as annually, based on the three original weighted averages provided by AWARE: agri, non-agri and unknown. This scale is often more practical than the watershed scale, which may be more challenging to identify, and should lead to the use of a more-spatially resolved water footprint metric.

为了执行缺水足迹（WSF），根据ISO标准14,046（2014），有必要将特定区域中消耗的水量与相应的本地缺水指标相乘。建议在开发这些因子的原始规模（分水岭规模）上优先使用这些因子。或者，提供国家/地区尺度因素以适应可能无法访问他们所评估的用水量所在的确切分水岭的从业人员。但是，这些因素具有很大的不确定性。在某些情况下，从业人员可以访问更高的空间分辨率信息，例如一个国家内的州，省或部门。因此，目前的工作提出了针对全球的次国家AWARE因素，使用国家以下边界作为流域和国家之间的解决方案。根据AWARE提供的三个原始加权平均值，分别和每月，每年为3428个行政区域提供因素：农业，非农业和未知。该标度通常比分水岭标度更实际，分水岭标度的确定可能更具挑战性，并且应导致使用在空间上更高分辨率的水足迹度量标准。
