Synergetic Benefits of Agricultural Sewage Reuse and Floating Photovoltaics in Mexican Wastewater System: A Municipal‐Level WEF Nexus Study

Global Challenges, Volume 10, Issue 1, January 2026.
This study proposes integrating treated sewage irrigation ponds with floating photovoltaics to enhance wastewater treatment plants’ financial viability in the Atoyac River Basin, central Mexico. The model demonstrates potential to strengthen the water‐energy‐food nexus by recycling one‐third of sewage, increasing irrigation acreage on cornlands ...

Intensifying Drought Patterns and Agricultural Water Stress in Erbil Governorate, Iraq: A Spatiotemporal Climate Analysis

Global Challenges, Volume 10, Issue 1, January 2026.
ABSTRACT Drought is a prolonged lack of rainfall that causes water shortages for agricultural land by reducing soil moisture and limiting crop yields. This study assesses the impacts of drought in Erbil, Iraq, using 28 years of data from the southern, central, and northern regions.

Evaluating Simulated Groundwater Contributions to Streamflow in a Data‐Scarce, Semi‐Arid Catchment in South Africa

Hydrological Processes, Volume 40, Issue 1, January 2026.
Calibration procedure selection should be carefully considered in data‐scarce circumstances, as good model efficiency does not necessarily guarantee a realistic representation of hydrological processes. Stable isotopes proved effective in validating model results and detecting shortcomings in the J2000 model caused by sparse hydroclimatic data and the ...

Linking remote sensing with crop modeling for yield and nitrate leaching predictions in Minnesota

Journal of Environmental Quality, Volume 55, Issue 1, January/February 2026.
Abstract Upscaling crop yield and nitrate‐N leaching loss from experimental sites to large areas under alternative crop rotations is crucial for assessing strategies and setting goals to protect groundwater quality at a regional scale. Nitrogen (N) rate field trials were used to calibrate the Environmental Policy Integrated Climate (EPIC) model for ...

Interpretable Temperature‐Based Deep Learning for Evapotranspiration: SHAP‐Based Feature Analysis in CNN‐GPU

Meteorological Applications, Volume 33, Issue 1, January/February 2026.
A comprehensive analysis of a computational model based on convolutional networks (CNN) using graphics processing units (GPU) was developed in the present study for reference evapotranspiration (ETo). The CNN‐GPU architecture demonstrates the high accuracy of the model by schematically showing the data flow from input to output, including convolutional
