Enhancing Reliable Irrigation–Water Supply in Poverty‐Ridden and Drought‐Prone Areas: Pre‐2017 Baseline Evidence From the Tawona Irrigation Scheme, Zimbabwe

Irrigation and Drainage, EarlyView.
ABSTRACT This study investigates farmers' willingness to pay for a reliable irrigation water supply in Zimbabwe's Tawona irrigation scheme, where intermittent water supply caused by funding shortages threatens irrigation sustainability. Using contingent valuation and logit regression analysis, data were collected from 313 farmers during the 2016/2017 ...

Les zones tampons humides artificielles pour réduire  les pollutions des nappes par les pesticides issus des réseaux de drainage : une innovation en marche ?

Sciences, Eaux & Territoires, 2015
Le maintien de « zones tampons » telles que les bandes enherbées permet de capter les transferts superficiels de produits phytosanitaires et les Zones Tampons Humides Artificielles (ZTHA), les transferts par les réseaux de drainage. Les premières peuvent

L’impact du drainage agricole souterrain sur la morphologie des petits cours d’eau dans la région de Cookshire, Québec [PDF]

Géographie physique et Quaternaire, 2007
Le drainage agricole souterrain a des effets sur l'hydrologie des bassins versants, ce qui, selon toute vraisemblance, se répercute sur la morphologie des cours d'eau. Cette note montre que, pour une même superficie de drainage, les petits cours d'eau des bassins versants où il y a drainage souterrain sont plus larges et de plus grande dimension que ...

From Indicator to Prediction: Five Decades of Biochemical Oxygen Demand Research in Tropical Freshwaters

World Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT Biochemical oxygen demand (BOD) remains a core indicator of organic pollution in freshwater monitoring, but its role in water policy and practice is changing as water‐quality assessment moves toward predictive, integrative, and decision‐support approaches.

Le rôle des réseaux de drainage agricole dans le ralentissement dynamique des crues : interprétation des données de l'observatoire « Orgeval » The role of agricultural drainage networks in the dynamic slowing of floodwaters: interpretation of the Orgeval observatory data [PDF]

Sciences, Eaux & Territoires, 2012
Le drainage agricole peut générer des impacts importants sur le cycle de l’eau, sur l’écologie du paysage et sur les cours d'eau. Sur le bassin versant expérimental de l’Orgeval, les équipes scientifiques d’Irstea étudient les processus de transfert des ...

Adding the Farmer Domain to Aquifer Recharge: Insights From Smallholder Farmers' Natural Water Retention Measures in the Danube–Tisza Interfluve, Hungary

World Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT This paper describes and analyzes recharge practices in Bács‐Kiskun County, Hungary, within what can be categorized as the farmer domain. Such locally embedded aquifer recharge practices remain underexplored in Hungary. Current research and funding largely focus on large‐scale Managed Aquifer Recharge (MAR) interventions emphasizing intended ...

An Investigation into the Grade Dynamics of Drainage Implements [PDF]

, 1985
The use of the trenchless plough drainage implement has increased in the past few years due to its efficiency and cost advantages over other methods. However, the performance of these machines when working in fields with irregular soil conditions is ...

Smart Sensor‐Integrated Lysimeter System for Affordable on‐Farm Crop Water Monitoring and Irrigation Management

Irrigation and Drainage, Volume 75, Issue 4, Page 1494-1505, Otober 2026.
ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

Multiobjective Simulation–Optimization of Crop Allocation and Water Resources in Canal Command Areas Using Genetic Algorithms

Irrigation and Drainage, Volume 75, Issue 4, Page 1592-1608, Otober 2026.
ABSTRACT This study develops an integrated simulation–optimization framework for sustainable crop allocation and water resource management in the Bargarh Canal Command (BCC), eastern India. Efficient irrigation allocation remains a critical challenge due to competing demands, groundwater–surface water interactions and environmental constraints ...

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

Irrigation and Drainage, Volume 75, Issue 4, Page 1574-1591, Otober 2026.
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 ...
