“…The HAI constructed in this research largely follows the evaluation index systems established by previous studies, encompassing population density, GDP, nighttime light, land cover, and road networks (Huang et al., 2022; Mu et al., 2022; Xu et al., 2016). However, given that grasslands occupy over 60% of the QTP (Li et al., 2019; Zeng et al., 2022), we employed grazing intensity (i.e., the number of grazing livestock per square kilometer) in lieu of previously used pasture area to improve the accuracy of quantifying human activities in grassland ecosystems. Additionally, unlike previous studies that typically assigned equal weights to all indicators, we adopted a different approach based on expert judgment.…”

As the Earth's Third Pole and the Asian water tower, the Qinghai‐Tibet Plateau (QTP) plays a key role in global climate regulation and biodiversity maintenance. Living in harmony with nature is vital for local and global sustainable development. Current research on the conflicted or coordinated relationship between humans and nature on the QTP at a fine spatial scale remains limited. To fill the gap, we developed the human activity intensity index (HAI) and eco‐environmental quality index (EQI) at 1‐km resolution and proposed a four‐quadrant diagram approach to explore the dynamics between them. The results show a coordinated development on the QTP as the HAI and EQI both increased from 2000 to 2020, and the ratio of coordinated areas to conflicted areas was 5:1. High HAI areas were mainly in big cities such as Xining, Lhasa, Haidong, Xigaze, and along traffic lines. The significant conflicted areas were mainly outside the Lhasa metropolitan, south of the Hengduan Mountains, and along some new roads, and reduced by 8% between 2000–2010 and 2010–2020. The area of high HAI but low EQI was the smallest proportion, mainly in southern Qinghai Lake, southern Brahlung Zangbo River, Gobi oases, and western transport lines, but it implies the highest risk of ecosystem degradation. This research expands the fundamental methodology to address complex human‐natural relationships and provides implications for the sustainable development of fragile ecosystems.

“…Areas with population densities surpassing 10 persons/hm 2 were assigned a pressure score of 10, while areas with densities below 10 persons/hm 2 were assigned scores on a logarithmic scale ranging from 0 to 10, following a mathematical equation (Zeng et al, 2022).…”

Wilderness plays a crucial role in biodiversity conservation, and its preservation represents a pivotal objective emphasized in the Post-2020 Global Biodiversity Framework (GBF). Nonetheless, wilderness frequently faces threats from the escalating impact of human activities, leading to significant repercussions on diverse ecological processes. Despite the abundance of previous studies on wilderness, there has been a limited focus on the temporal dynamics at the local scale, as well as on identifying the conservation priorities in terms of their ecosystem services. In this study, taking the Lhasa River Basin in the Qinghai-Tibet Plateau of China as an example, the spatio-temporal variations of wilderness were analyzed, and conservation priorities of them were further identified based on ecosystem services. The results revealed a persistent decline in the wilderness from 1990 to 2020, particularly in terms of bare land and grassland. Furthermore, we identified that 33.56% of the remaining wilderness necessitated special attention. These findings offer valuable insights into potential future threats to wilderness and hold critical importance for formulating regional conservation strategies at the local scale.

“…Compared to previous HFP maps, these HFP maps significantly improved those underestimated regions and can reveal continuous changes in the HFP record. This dataset has been applied to studies on biodiversity and habitat quality (Gao et al, 2022; Zeng et al, 2022). The HFP index can be used as a multifactor composite indicator of anthropogenic drivers of AGBC loss, however, the spatiotemporal variation of AGBC loss due to increased HFP has not been thoroughly studied.…”

Human activities have placed significant pressure on the terrestrial biosphere, leading to ecosystem degradation and carbon losses. However, the full impact of these activities on terrestrial biomass carbon remains unexplored. In this study, we examined changes in global human footprint (HFP) and human‐induced aboveground biomass carbon (AGBC) losses from 2000 to 2018. Our findings show an increasing trend in HFP globally, resulting in the conversion of wilderness areas to highly modified regions. These changes have altered global biomes' habitats, particularly in tropical and subtropical regions. We also found accelerated AGBC loss driven by HFP expansion, with a total loss of 19.99 ± 0.196 PgC from 2000 to 2018, especially in tropical regions. Additionally, AGBC is more vulnerable in the Global South than in the Global North. Human activities threaten natural habitats, resulting in increasing AGBC loss even in strictly protected areas. Therefore, scientifically guided planning of future human activities is crucial to protect half of Earth through mitigation and adaptation under future risks of climate change and global urbanization.
