“…Globally, the expansion of human activities is having a major impact on natural habitats, seriously threatening ecosystem function and integrity. Human activities, such as the expansion of impervious surfaces, agricultural practices, population growth, and economic development, are causing irreversible damage to natural habitats, with basin regions experiencing increasingly pronounced effects [1,2]. Understanding the intricate interplay between human activities and natural habitats within the Yangtze River Basin (YRB) is imperative given its status as the third-largest basin globally [3].…”

Globally, natural habitats have suffered tremendous damage from human activities, a phenomenon that is increasingly evident in basin regions. The management of natural habitats in basin regions is dependent on understanding of the various impacts of human activities on these ecosystems. Despite the various studies that have been conducted on the effects of human activities on habitats in basin regions, there is still a lot of doubt regarding the impact of these activities on the quality of basin ecosystems. To fill this gap, this study employs a series of spatial analysis methods and logistic regression modeling to delve into the spatial and temporal patterns of human activities and habitat quality in the Yangtze River Basin (YRB) as well as the differences in the impacts of human activities on habitat quality in the sub-basins of the YRB. The findings indicate a 0.408% decline in the overall environmental quality of the YRB area from 2000 to 2020, accompanied by a 15.396% surge in human activities. Notably, the southeastern Qilian Mountains and the mountainous regions in the northwestern sector of the Sichuan Basin emerge as pivotal areas for habitat quality restoration. Conversely, the southwestern Qilian Mountains and the urban clusters in the Yangtze River Delta (YRD) face significant habitat quality deterioration. Spatial regression analyses reveal a noteworthy trend: the burgeoning human activities in the Yangtze River region pose a substantial threat to habitat recovery efforts. Further differential analyses focusing on the upper, middle, and lower basin segments underscore that human activities exert the most pronounced impact on habitat quality within the lower basin region, while the upper basin experiences the least influence. The implications of this study are manifold. It furnishes valuable policy insights for the comprehensive management and targeted preservation of habitats across the YRB. By delineating areas of habitat restoration and degradation and highlighting the differential impacts of human activities across basin segments, this research lays a solid foundation for informed decision making in habitat conservation and ecosystem management within the YRB.

“…At present, topographic factors, climatic factors, and anthropogenic activities play an important role in changing habitat quality. Among these factors, the disturbance of anthropogenic activities most notably shifts the overall regional ecological pattern and degrades and destroys the habitat quality (Gao et al, 2022). Therefore, this study INVEST gates the mechanisms of different factors on habitat quality and the interaction between its two factors by introducing a geographic detector model (Zhu and Kasimu, 2020;Zhang et al, 2022).…”

Understanding the characteristics of habitat quality and its influence under land use change is crucial for rapid urbanization, regional ecological protection, and national restoration and optimization of the ecological layout. This paper examined Anhui Province, China, through topo-graphic data, climate data, human activity data, and land use data from 2000, 2010, and 2020. To reveal the habitat quality impact mechanisms, the paper assessed the province’s spatiotemporal evolution characteristics of habitat quality by the Patch-generating Land Use Simulation (PLUS) model, Integrated Valuation of Ecosystem Services and Trade-offs (INVEST) model, and geo-graphic probe model. The results showed that: 1) From 2000 to 2020, Paddy field, Dryland, and Wooded land covered 70% of the study area. From 2000 to 2020, the integrated land use dynamic attitude was 0.51%, with active changes in the Paddy field, Dryland, and open Wooded land and a continuous increase in dynamic attitude. Compared to 2020, the spatial distribution characteristics of land use types in 2030 remain largely unchanged. However, Paddy fields and Drylands still show an increasing trend, while Wooded land, Reservoir ponds, and Urban land demonstrate a small decreasing trend. All other land types remain unchanged; 2) Secondly, between 2000 and 2020, habitat quality gradually decreased, while the percentage of poor habitat quality increased by 1.47% and the percentage of worse habitat quality decreased by −1.41%. All other classes exhibited a small decreasing trend; the mean habitat quality decreased by 0.01 compared to 2020 in 2030, and was mainly distributed in the southwestern and eastern edges of the province; and 3) DEM, aspect, precipitation, and evapotranspiration have a high explanatory power for habitat quality, while the variable Places has significantly increased its explanatory power for habitat quality between 2010 and 2020. Natural factors laid down the graded distribution pattern of habitat quality, and the location and intensity of human activities drove the evolution of habitat quality. Analyzing the mechanism behind habitat quality in Anhui Province provides a theoretical basis for ecological restoration and ecological planning.

“…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.…”

“…However, a more continuous temporal resolution allows for a more sensitive capture of the negative human impact on AGBC. This is mainly due to the immediate response of AGBC to human activity, for example, AGBC stocks drop from 70 to 10 MgC ha −1 when the northern hardwood forests were cleared (Houghton, 2005) 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.
