Widespread spring vegetation greening (inferred by LAI) in the Northern Hemisphere leads to additional summer soil moisture (SM) deficits through increasing transpiration. Meanwhile, vapor pressure deficit (VPD) has also been rising, which can increase atmospheric evaporative demand. However, extent and magnitude of influence these two factors on SM changes have not elucidated. Here, based state-of-the-art reanalysis remote sensing data, we use three statistical methods quantify contributions LAI VPD deficit. The results show that contributes more change than southwestern northern regions North America, northeastern Europe, central southeastern Asia, covering 13.4% vegetated areas despite certain drying. are great significance for climate adaptation enhancement surface water management.

Abstract The impact of soil moisture (SM) and vapor pressure deficit (VPD) on gross primary productivity (GPP) variability in ecosystems is a topic significant interest. Previous studies have predominantly focused real-time associations between SM, VPD, carbon uptake, attributing SM as the principal driver GPP due to its direct indirect effects through VPD. Using an information theory-based process network approach, we discovered that influence past mediated emerges across tropical regions. VPD conditions directly also affect alongside GPP, which subsequently impacts variability. Examining land-atmosphere feedback using theory reveals but not reverse. These causal structures explain consistent decline with increasing trends observed regions, are trends. Our findings emphasize importance considering by when analyzing complex land-vegetation-atmosphere interactions.

ABSTRACT Water redistribution during rain events in drylands plays a critical role the persistence and spatial pattern of vascular plants these patchy ecosystems. Biological soil crusts (BSCs) form membrane surface mediate ecohydrological dynamics. However, little is known about their influence on dryland ecosystem state under changing climate, which may alter total annual rainfall intraannual regime. Building existing models, we develop model that considers BSC–vascular plant interactions realistic dynamics pulses. We find presence BSCs often increases resilience by promoting runoff to high aridity. benefit comes at cost biomass relatively wetter conditions; threshold BSC effect occurs when water losses from exceed routing plants. Increased BSCs, own persistence, can be promoted finer soils regimes less frequent events—projected for many drylands. Lastly, feedbacks underlying self‐organization hence formed patterns. In aridity, likely ameliorate competition between through large scale promotion, reducing regularity. Our analysis highlights significantly shape drylands' response climate change positive effects stronger more pervasive drier future, but such benefits come productivity aridity outside range.
