Point de vue - La recherche de l’efficience maximum de l’eau, un objectif à ne pas déconnecter d’une vision intégrée du système de production [PDF]

Sciences, Eaux & Territoires, 2020
Le goutte-à-goutte, et plus encore le goutte-à-goutte enterré, sont des techniques particulièrement plébiscitées pour irriguer les cultures dans les régions où la ressource en eau est une contrainte majeure.

Module optionnel, intégré dans l'outil de conseil en irrigation OSIRI-Run : aide à la décision de l'agriculteur pour la suspension de l'irrigation sur l'exploitation en fonction de la pluie, du sol et de ses choix techniques. (MAIA : Module d'Ajustement de l'Irrigation par l'Agriculteur) [PDF]

, 2007
L'outil de conseil en irrigation comprend, dans sa version initiale (Chopart et coll. 2005), un module proposant à l'agriculteur d'adapter le conseil OSIRI-Run en fonction des pluies réelles entre deux actualisations de l'état des réserves hydriques. Les

Clogging Analysis in Drip Irrigation Systems: CFD and DEM Approaches

Irrigation and Drainage, Volume 74, Issue 4, Page 1395-1409, October 2025.
ABSTRACT Clogging represents a critical challenge that undermines the efficiency and sustainability of drip irrigation systems by inducing uneven water distribution and increasing maintenance requirements. In this study, the phenomenon of clogging in drip emitters was investigated via computational fluid dynamics (CFD) in conjunction with the discrete ...

Land Cover Changes Following Biogas Development Across Different Farm Types: A Nationwide Study in France

GCB Bioenergy, Volume 17, Issue 10, October 2025.
The French biomethane market is one of the fastest growing in Europe, with farms increasingly using energy cover crops as feedstock for their biogas plants. Our study highlights a diversity of land cover changes following biogas plant implementation, depending on‐farm characteristics and location.

Water productivity and economic feasibility of drip irrigation system investment in tomato cultivation: Case of northeastern Tunisia

Irrigation and Drainage, Volume 74, Issue 3, Page 1010-1017, July 2025.
Abstract Tunisia is characterized by water scarcity, growing water demand and considerable waste of this resource especially in the agricultural sector. To cope with this situation and enhance water productivity, appropriate utilization of advanced irrigation methods such as drip irrigation is highly needed.

A new method of estimating infiltration parameters for furrow irrigation

Irrigation and Drainage, Volume 74, Issue 2, Page 658-672, April 2025.
Abstract In this study, we present new two‐point and one‐point methods for estimating infiltration parameters in furrow irrigation. It is assumed that infiltration and waterfront advance along the furrow follow the Valiantzas two‐parameter infiltration and power advance equations, respectively.

An assessment of future climatic and anthropogenic impacts on the hydrological system of a semi‐arid catchment

Irrigation and Drainage, Volume 74, Issue 2, Page 834-860, April 2025.
Abstract Climate and catchment characteristics, particularly land and water use and management, may vary according to the population growth rate, future food habits and water demands. Three climate simulations corresponding to the Intergovernmental Panel on Climate Change, Special Report on Emissions Scenarios (A1B) were downscaled using the ‘Providing

Stratégies de gestion des irrigations sur les vertisols de Guadeloupe [PDF]

, 1999
L'irrigation des vertisols de Guadeloupe a connu des échecs imputables à une compréhension insuffisante des mécanismes des transferts hydriques. Les travaux de recherches entrepris par l'Inra et le Cirad ont permis de relier la disponibilité de l'eau ...

Improved understanding of soil water content at field capacity and estimates from pedotransfer functions

Irrigation and Drainage, Volume 74, Issue 2, Page 516-528, April 2025.
Abstract The soil water content at field capacity, θFC, is a fundamental variable for irrigation and agriculture. This study determines the optimal tension (−33 or −10 kPa) of deriving θFC which best matches the in situ field measurements following the Veihmeyer procedure.
