Arid and humid ecosystems are undergoing significant changes over the past decades due to warming temperature frequent occurrence of climate extremes. Quantifying climatic vegetation sensitivity in regions with different classifications is crucial for understanding interaction mechanisms between ongoing change. However, such knowledge about spatiotemporal variations its driving factors arid still unclear. Based on this consideration, a moving-window-based Vegetation Sensitivity Index (VSI) scheme was applied Enhanced (EVI), Leaf Area (LAI), Solar-induced Chlorophyll Fluorescence (GOSIF) data evaluate terrestrial ecosystem response explore from 2003 2020. Results indicated that high VSI (>60) observed tropical rainforests central Eurasia semi-arid regions. By contrast, low (<40) typically Spatially, we found exhibited nonlinear parabolic variation along gradient aridity index but generally presented linear an upward trend Temporally, showed declining two displayed significantly increasing areas. Temperature dominant factor explain spatial globally, while precipitation mainly dominated temporal VSI. The varied across as were main drive classifications, respectively. Our results provide unique insights into future change classifications.

Vegetation response to soil and atmospheric drought has raised extensively controversy, however, the relative contributions of drought, their compound droughts on global vegetation growth remain unclear. Combining changes in moisture (SM), vapor pressure deficit (VPD), (normalized difference index [NDVI]) during 1982-2015, here we evaluated trends these three types quantified impacts NDVI. We found that VPD increased 0.22 ± 0.05 kPa·decade-1 this trend was doubled after 1996 (0.32 0.16 ) than before (0.16 0.15 ). Regions with large increase generally accompanied decreasing SM, leading a widespread increasing across 37.62% land areas. further dominated browning since late 1990s, contributing declined NDVI 64.56%. Earth system models agree dominant role growth, but negative magnitudes are considerably underestimated, half observed results (34.48%). Our provided evidence droughts-induced browning, highlighting importance correctly simulating ecosystem-scale under-appreciated exposure as it will climate change.

Despite the mounting attention being paid to vegetation growth and their driving forces for water-limited ecosystems, relative contributions of atmospheric soil moisture dryness stress on are an ongoing debate. Here we comprehensively compare impacts high vapor pressure deficit (VPD) low water content (SWC) in Eurasian drylands during 1982-2014. The analysis indicates a gradual decoupling between over this period, as former has expanded faster than latter. Moreover, VPD-SWC relation VPD-greenness both non-linear, while SWC-greenness is near-linear. loosened coupling VPD SWC, non-linear correlations among VPD-SWC-greenness area extent which SWC acts dominant factor all provide compelling evidence that more influential stressor drylands. In addition, set 11 Earth system models projected continuously growing constraint towards 2100. Our results vital dryland ecosystems management drought mitigation Eurasia.

Abstract Droughts have been implicated as the main driver behind recent vegetation die‐off and are projected to drive greater mortality under future climate change. Understanding coupling relationship between drought has of great global interest. Currently, is mainly evaluated by correlation coefficients or regression slopes. However, optimal timescale response drought, a key indicator reflecting sensitivity largely ignored. Here, we apply identification method examine change in over past three decades (1982–2015) with long‐term satellite‐derived Normalized Difference Vegetation Index Standardized Precipitation‐Evapotranspiration data. We find substantial increasing timescales globally, coefficient overall declines 1982 2015. This decrease vegetation–drought observed regions water deficit, although its initial relatively high. water‐surplus regions, low earlier stages, prone show an trend. The changes may be driven trend atmospheric CO 2 . Our findings highlight more pressing risk than water‐deficit which advances our understanding provides essential insights for mapping changing conditions.

Precipitation is an important factor influencing the date of foliar senescence, which in turn affects carbon uptake terrestrial ecosystems. However, temporal patterns precipitation frequency and its impact on senescence remain largely unknown. Using both long-term flux data satellite observations across Northern Hemisphere, we show that, after excluding impacts from temperature, radiation total by partial correlation analysis, declining may drive earlier 1982 to 2022. A decrease intensifies drought stress reducing root-zone soil moisture increasing atmospheric dryness, limit photosynthesis necessary for sustained growth. The enhanced acclimation, showing a more rapid response drought, also explains positive relationship between date. Finally, find 30 current state-of-art Earth system models fail capture sensitivity DFS changes incorrectly predict direction correlations approximately half northern global lands, historical simulations future predictions. Our results therefore highlight critical need include frequency, rather than just precipitation, into accurately forecast plant phenology under climate change. leaf senescence.

Globally, vegetation has been changing dramatically. The vegetation–water dynamic is key to understanding ecosystem structure and functioning in water-limited ecosystems. Continual satellite monitoring detected global greening. However, a greenness increase does not mean that functions increase. intricate interplays resulting from the relationships between precipitation must be more adequately comprehended. In this study, data, for example, leaf area index (LAI), net primary production (NPP) rainfall use efficiency (RUE), were used quantify dynamics their relationship with different reaches of Yellow River Basin (YRB). A sequential regression method was detect trends NPP sensitivity rainfall. results showed 34.53% YRB exhibited significant greening trend since 2000.
