How Will Higher Interannual Precipitation Variability Intensify Water Stress Under a Drying Climate?

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Climate change is expected to alter both the mean and variability of precipitation. Hydrological consequences of higher precipitation variability remain less understood than that induced by changes in precipitation mean. This study evaluates the combined effects of changes in annual precipitation mean and variability on runoff and water supply

Leveraging the TabPFN Algorithm for High‐Resolution Mapping of Groundwater Bicarbonate and Its Scaling Risk Across China

open access: yesWater Resources Research, Volume 62, Issue 5, May 2026.
Abstract Large‐scale groundwater quality prediction is often constrained by sparse sampling, limiting the reliability of spatial assessments. This study introduces Tabular Prior‐data Fitted Network (TabPFN), a machine learning model based on prior‐fitting networks, to address this challenge and enable high‐precision mapping of groundwater bicarbonate ...

Detection of Heat and Drought Effects on the Photosynthetic Activity Using Solar‐Induced Chlorophyll Fluorescence and a Photochemical Reflectance Index in a Cool‐Temperate Larch Forest in Japan

open access: yesEcological Research, Volume 41, Issue 3, May 2026.
Solar‐induced chlorophyll fluorescence (SIF) and gross primary productivity decline at midday during a short heatwave in a tower site of a larch forest. High atmospheric vapor pressure deficit significantly reduced the photochemical reflectance index (PRI), light‐use efficiency (LUE), and canopy fluorescence emission efficiency (εF).

Efficiency of Spatial Subsidies Under Information Constraints: A Case Study

open access: yesAgricultural Economics, Volume 57, Issue 3, May 2026.
ABSTRACT This study compares the efficiency of homogeneous versus spatially heterogeneous subsidies in developing agricultural plans compatible with bird sustainability. Using the plains of Lleida as a case study—where incentives for agricultural intensification threaten a bird community‐we employ a spatially explicit model that simulates crop yields ...
