Disentangling the relative effects of soil moisture and vapor pressure deficit on photosynthesis in dryland Central Asia

Ecological Indicators, Journal Year: 2022, Volume and Issue: 137, P. 108698 - 108698

Soil moisture (SM) and vapor pressure deficit (VPD) are key factors affecting photosynthesis, quantifying their effects on this process can help us to understand the mechanisms of carbon cycling in terrestrial ecosystems. However, strong coupling SM VPD makes it difficult quantify relative importance ecosystem cycle. In study we decoupled negative correlation between by sorting binning reanalysed data, based this, quantified relationship sunlight-induced chlorophyll fluorescence (SIF) dryland Central Asia (CA). We found that promoted suppressed photosynthesis CA, accounting for 94.08% 5.92% vegetated areas respectively; CA accounted 39.68% 60.32% vegetation area, respectively. The different types were different: croplands forests tended increase then decrease with increasing SM, grasslands, shrublands sparse SM; croplands, grasslands VPD, while opposite is true vegetation. Relative indicated where had a greater effect than 74.26% mainly central part Kazakhstan Kyrgyzstan, which was related fact main these regions located northern most Uzbekistan Turkmenistan (25.74% areas).

The relative role of soil moisture and vapor pressure deficit in affecting the Indian vegetation productivity

Environmental Research Letters, Journal Year: 2023, Volume and Issue: 18(6), P. 064012 - 064012

Published: May 5, 2023

Abstract Atmospheric aridity (vapor pressure deficit, VPD) and soil moisture (SM) deficit limit plant photosynthesis and, thus, affect vegetation carbon uptake. The strong correlation between SM VPD makes it challenging to delineate their relative contributions regional productivity. Addressing this gap is vital understand the future trajectory of productivity in India—the second-highest contributor global greening. Here, we separate controls on Indian using statistical causal analysis. We found that India primarily controlled by limitation (87.66% grids) than (12.34% grids). Vegetation has a varying association with across different agroecological regions India. negative impact uptake not visible high-rainfall areas These findings advance our understanding dynamics under dryness stress can enhance dynamic model estimates for changing climate scenarios.

Woody vegetation plays a vital role in regulating the water budget and energy exchange Earth's system. This study aimed at analyzing spatiotemporal variability of Normalized Difference Vegetation Index (NDVI) its response to Potential Evapotranspiration (PET), rainfall (RF), soil moisture (SM), temperature (TEM) area. The trends, correlations, relationships between NDVI climate variables were executed using Mann-Kendall monotonic trend (MKMT), partial correlation coefficients (PCC), multiple linear regression (MLR) methods, respectively. Over last 26 years, interannual increased by 0.0065 yr-1 (R2 = 0.159, p 0.157). MKMT Theil-Sen slope analysis showed that significantly 78% basin's total Of basin, 31%, 47%, area extremely significant increasing (Zmk 4.706, ≤ 0.01), trends 2.378, 0.05) variation was well explained 0.88, Adjusted R2 0.84) eastern, southeastern, central sub-basins where agriculture, grass, sparse barelands are predominant land use cover (LULC) classes. main climatic factors control growth greenness during rainy season found be PET, SM, RF with 0.91, 0.99, 0.86 PCC current broadens scientific community's understanding relationship highland ecosystems.
