Machine Learning‐Based Estimation of Reference Evapotranspiration and Crop Coefficients for Wheat Under Diverse Climatic Conditions

Irrigation and Drainage, EarlyView.
ABSTRACT Accurate estimation of reference evapotranspiration (ET0) and crop coefficients (Kc) is critical for irrigation planning, particularly in data‐limited regions where agriculture dominates freshwater consumption. Although machine learning (ML) methods have been widely applied to ET0 and Kc estimation, most studies address these parameters ...

Drivers and Challenges of Micro‐Irrigation Adoption and Intensity in India: A Study of Four States

Irrigation and Drainage, EarlyView.
ABSTRACT India's food security relies substantially on groundwater, but inefficient irrigation is seriously depleting this resource. Micro‐irrigation (MI) improves irrigation application efficiency and productivity, yet adoption remains low. This study examines MI adoption across four major Indian states—Uttar Pradesh, Maharashtra, Madhya Pradesh and ...

Trajectoires paysagères contemporaines et sources de contaminants potentiels dans deux bassins versants à usages mixtes : un regard spatialisé de la qualité de l’eau

Sciences, Eaux & Territoires
La qualité des cours d’eau a profondément été affectée par les transformations paysagères de ces dernières décennies. Les projets IDESOC (ZABR, 2021-2024) et CHYPSTER (ANR, 2021-2026), en croisant géographie, hydrologie et biogéochimie proposent d ...

Variable Rate Irrigation: A Long‐Term Simulated and Field Data Analyses of Irrigation Practices, Field Variability, Economic Feasibility and Profitability

Irrigation and Drainage, EarlyView.
ABSTRACT Long‐term economic analyses of variable rate irrigation (VRI) strategies were performed compared with uniform irrigation management (UIM) in a reference production field using the AquaCrop model. Five strategies to trigger irrigation were as follows: (Field Capacity‐VRI, Driest Soil Trigger‐VRI, Water Mining‐VRI, Conventional Uniform ...

Inline Oxygenation in Drip‐Irrigated Citrus: How Much Agrochemical Reduction Is Needed to Achieve Net Environmental Benefits?

Irrigation and Drainage, EarlyView.
ABSTRACT The agronomic benefits of oxygen‐enriched irrigation, such as improved root development, enhanced nutrient uptake, and reduced fertiliser and pesticide requirements, are well documented. However, incorporating oxygenation devices into fertigation systems increases energy demand and material use, thereby incurring additional environmental ...

A Holistic Assessment of Water Footprint and Irrigation Performance Indicators With Respect to Agricultural Water Productivity

Irrigation and Drainage, EarlyView.
ABSTRACT Global warming has intensified prolonged droughts in many regions, including Türkiye, resulting in growing pressure on already limited water resources. Agriculture, as the largest water‐consuming sector, faces critical challenges in sustaining productivity under increasing water scarcity. In this context, assessing water use efficiency through
