Projections of Meteorological Drought and Potential Evapotranspiration Using the RegCM4 Over Northeastern Iran

International Journal of Climatology, Volume 46, Issue 10, August 2026.
We downscale CanESM2 with the Regional Climate Model version 4 (20 km) and evaluate against 15 stations to derive monthly PET (Hargreaves–Samani) and SPEI for northeastern Iran (1990–2009, 2040–2059, 2080–2099). Results show robust PET increases and a shift toward more negative monthly SPEI—especially April–September—indicating earlier onset and longer

Utilization of Membrane Bioreactor (MBR)–Treated Wastewater in Irrigation of Safflower (Carthamus tinctorius L.) Under Mediterranean Conditions

Water Environment Research, Volume 98, Issue 8, August 2026.
Industrial wastewater was treated using a membrane bioreactor (MBR) and applied to safflower (Carthamus tinctorius L.) under drip irrigation conditions with four different irrigation strategies. The agronomic performance, water use efficiency (WUE), and soil salinity dynamics were evaluated to assess the feasibility of reuse of treated wastewater as an

Widespread Increase in Global Plant Water Stress Obscured by Greening

AGU Advances, Volume 7, Issue 4, August 2026.
Abstract Understanding the vulnerability of plants to more severe and frequent drought events and developing adaptive management strategies requires robust methods for quantifying long‐term changes in plant water stress (PWS). Most data‐driven explorations of long‐term trends in PWS have focused on alterations in canopy structure (e.g., leaf area index)

Climate‐Induced Severe Water Scarcity Events as Harbingers of Global Wheat Price

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract This study connects the dots between global extent of severe water scarcity (SWS) events and spikes in food price. The authors start with three staple crops (rice, wheat, and maize) using a empirical but crop specific characterization of severe water scarcity occurrence, which is defined based on the area of land cultivated with each studied ...

Ensemble‐Based Parameter Estimation for an Unconfined Groundwater Model of a Small Island Considering Tidal Overheight

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Tidal influences are rarely considered in parameter estimation procedures for coastal groundwater flow models. Yet, considering tides adds to the already high computational burden associated with such models due to the presence of density‐dependent flow.

Deep Soil Drying Increases Dryland Apple Tree's Eco‐Physiological Sensitivity to Atmospheric Drought

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Dryland tree survival critically depends on deep soil water (DSW), particularly during dry spells. However, DSW is often limited and can be exhausted during periods of active tree growth, as recharge from precipitation is minimal. The eco‐physiological responses of trees to compound droughts (i.e., combined deep soil and atmospheric droughts ...
