Global variations in critical drought thresholds that impact vegetation

Xiangyi Li et al.

Summary: This study presents a globally applicable framework for identifying drought thresholds for vegetation responses to different levels of soil-moisture deficits. The identified thresholds represent critical inflection points for changing vegetation responses to drought stress and serve as a warning signal for substantial vegetation impacts. The results have implications for assessing the response of land ecosystems to climate change and variability.

Assessment of the importance of increasing temperature and decreasing soil moisture on global ecosystem productivity using solar-induced chlorophyll fluorescence

Chaoya Dang et al.

Summary: Accurate assessment of global gross primary productivity (GPP) is crucial for estimating the global carbon cycle. This study uses solar-induced chlorophyll fluorescence (SIF) as a proxy for GPP and investigates the impact of soil moisture (SM) and temperature (Ts) changes on SIF. The results show that Ts plays a more important role in SIF in 60% of the vegetation areas, but the importance of SM and Ts varies across different vegetation types and climate zones.

Atmospheric dryness reduces photosynthesis along a large range of soil water deficits

Zheng Fu et al.

Summary: Soil water content affects GPP differently from atmospheric dryness, with an increase in GPP with high soil water content but a decrease when below a threshold. Atmospheric dryness always negatively affects GPP. Earth System Models underestimate the effects of atmospheric dryness and soil water content on GPP.

Exceptional heat and atmospheric dryness amplified losses of primary production during the 2020 US Southwest hot drought

Matthew P. Dannenberg et al.

Summary: Earth's ecosystems are facing increasing threats from hot drought, which can have significant impacts on the carbon cycle. Through a natural experiment, it was found that hot drought leads to a significant reduction in gross primary production (GPP), with both meteorological and hydrological factors playing a role. Future increases in air temperature and vapor pressure deficit may lead to more frequent and intense hot droughts, exacerbating the reduction in GPP caused by drought.

Exploring complex water stress-gross primary production relationships: Impact of climatic drivers, main effects, and interactive effects

Huan Wang et al.

Summary: There is still debate about the dominance of vapor pressure deficit (VPD) and soil water content (SWC) in plant water stress. In this study, using statistical methods and extreme gradient boosting models, we found that VPD was more important than SWC for plant water stress. The study also revealed the interaction effect between VPD and SWC, and a threshold effect for VPD stress on gross primary production (GPP) loss.

A shift in the dominant role of atmospheric vapor pressure deficit and soil moisture on vegetation greening in China

Yongming Cheng et al.

Summary: This study assesses ecosystem productivity in China using solar-induced chlorophyll fluorescence (SIF) and finds that vapor pressure deficit (VPD) and soil moisture (SM) have significant effects. The land-atmosphere interaction mechanism is more notable near the agro-pastoral ecotone. The study also reveals that soil moisture has become the dominant factor in vegetation productivity since 2007.

Monitoring drought impacts on crop productivity of the US Midwest with solar-induced fluorescence: GOSIF outperforms GOME-2 SIF and MODIS NDVI, EVI, and NIRv

Ruonan Qiu et al.

Summary: The frequency and severity of drought are increasing in the context of global warming. This study used satellite-derived data to evaluate the impacts of the 2012 drought on crop productivity in the U.S. Midwest. The results showed that SIF and vegetation indices were able to capture the changes in photosynthesis due to water and heat stresses, with GOSIF data being the most effective in monitoring crop response to drought.

Increased Global Vegetation Productivity Despite Rising Atmospheric Dryness Over the Last Two Decades

Yang Song et al.

Summary: This study provides a comprehensive evaluation of the impacts of rising atmospheric dryness, temperature, and CO2 concentration on global vegetation productivity over the last two decades. It finds that despite the negative impact of increasing VPD, the warming and CO2 fertilization effects contribute to a widespread increase in vegetation productivity.

Significant water stress on gross primary productivity during flash droughts with hot conditions

Xiazhen Xi et al.

Summary: This study analyzed data from 35 global FLUXNET stations and found the impact of water stress on GPP during flash droughts. The results showed that low SM and high VPD are the dominant sources of water stress during flash droughts.

Effects of soilmoisture, net radiation, and atmospheric vapor pressure deficit on surface evaporation fraction at a semi-arid grass site

Bing Tong et al.

Summary: Surface energy partitioning, influenced by soil moisture, net radiation, and vapor pressure deficit, plays a crucial role in land-atmosphere coupling. This study investigates the impact of these factors on surface evaporation fraction (EF) using observations from a semi-arid grassland site in China. The results suggest that the effect of one factor on EF is influenced by the other two factors. Soil moisture tends to increase EF, while increased vapor pressure deficit weakens the relationship between soil moisture and EF. Path analysis shows that soil moisture, net radiation, and vapor pressure deficit not only directly affect EF, but also indirectly affect EF through canopy conductance and temperature difference between land surface and air.

Characterization of agricultural drought propagation over China based on bivariate probabilistic quantification

Yang Xu et al.

Summary: This study investigated the spatiotemporal variations of the propagation characteristics from meteorological drought to agricultural drought in China. Results show that the strongest correlation between meteorological and agricultural drought was in summer, with shorter propagation time, while the correlation and propagation sensitivity were greater in humid areas.

Summary: Researchers used satellite data to generate a global long-term GPP dataset and found that NIRv can accurately capture the seasonal and annual variations of GPP. Analysis at 104 flux sites showed that this dataset can effectively estimate global vegetation primary productivity.
