Viewpoint: Irrigation water management in a space age
Abstract Climate change and rapid population growth are already putting increasing demand and pressure on the world's freshwater resources. Irrigated agriculture is responsible for about 70% of global freshwater withdrawals, consuming the most amount of water.

Abstract Despite the attention given to the water–energy–food nexus, there is little field evidence of how this plays out for irrigators. This article analyses the diversity of irrigation system configurations and their related water and energy use in semi‐arid Morocco, where groundwater‐fed and pressurized drip irrigation, although supposedly thrifty,

Abstract Discharging of moisture and salt from unsaturated soil has always been a difficult problem. Therefore, a laboratory experiment in unsaturated soil, under drip irrigation, on subsurface drainage and soil desalination through subsurface drainage pipes (SDP) was conducted for using soil flume, where artificial macropore flow tubes (MFT) were ...

Impact hydrochimique d'une ballastière en eau sur les eaux souterraines [PDF]
La notion d'impact d'une ballastière en eau sur la qualité des eaux souterraines comporte deux aspects : impact naturel et impact artificiel dû à une pollution accidentelle. L'évaluation de ces deux types d'impact a été menée pour deux ballastières de l'aquifère rhénan alsacien.

Étude quantitative des ressources en eau souterraine
The aquifer system in the Lower Laurentians region of southwestern Quebec is hosted primarily by Cambro-Ordovician fractured sedimentary rocks that are part of the geological province known as the St. Lawrence Platform. The most transmissive unit of the aquifer is found at the top of the rock sequence and consists of highly fractured rocks and a layer ...

Valorisation de l’eau par l’élevage bovin : enseignements tirés de longs suivis d’exploitations dans le plateau du Saïs [PDF]
La contrainte hydrique constitue un facteur limitant avéré de la production agricole dans un pays aride à semi-aride comme le Maroc. Dans cette étude, la valorisation de l’eau par l’élevage bovin a été étudiée, dans des exploitations du plateau du Saïs ...

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

Beyond the Metrics: Context‐Aware Calibration for Better Drain Flow Modelling
ABSTRACT Robust hydrological and water quality modelling is essential for advancing the understanding and management of engineered agricultural subsurface drainage systems. Achieving credible model output hinges on calibration strategies that are both rigorous and context sensitive. At the field scale, accurately capturing the dynamics of nutrient load
