Global 100m Terrestrial Human Footprint (HFP-100)

Maps depicting the intensity of human pressure on the environment have become a critical tool for spatial planning and management, monitoring the extent of human influence across Earth, and identifying critical remaining intact habitat. Yet, these maps are often years out of date by the time they are available to scientists and policy-makers. Here we provide an updated Human Footprint methodology to run on an annual basis to monitor changing anthropogenic pressures. Software and methods are parameterized to enable regular updates in the future. In addition, we release a 100-meter global dataset for the years 2015–2019 and 2020 based on land use, population, infrastructure, and accessibility data. Results show high levels of agreement in validation against expert-interpreted satellite imagery and improved performance compared to previous iterations of similar datasets. These maps are directly relevant to measuring progress towards national and international targets related to biodiversit...

描绘人类对环境施压强度的地图，已成为空间规划与管理、监测全球人类活动影响范围，以及识别现存关键未受干扰栖息地的关键工具。然而，这类地图往往在可供科学家与政策制定者使用时，已滞后数年之久。于此，我们提出一种可年度运行的更新版人类足迹（Human Footprint）方法学，用以监测人为活动压力的动态变化。该软件与方法已完成参数化配置，可支持未来的常态化更新。此外，我们基于土地利用、人口、基础设施与空间可达性数据，发布了2015年至2019年及2020年的100米分辨率全球数据集。验证结果显示，该数据集与专家解译的卫星影像吻合度极高，且相较于此前同类数据集的迭代版本，其性能得到显著优化。此类地图可直接用于衡量各国及国际社会在生物多样性相关目标上的推进进度……
