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

A Coupled AquaCrop–Richards Model for Improved Crop Yield Prediction Through Physically Based Soil Water Dynamics

Irrigation and Drainage, EarlyView.
ABSTRACT Crop modelling is essential for agricultural water management but often relies on simplified water balance routines that limit representation of soil moisture dynamics. To address this limitation, we developed a coupled model that integrates the 1‐D Richards equation, solved using a finite difference method into the FAO AquaCrop.

Farmers' Soil–Water Management Practices and Perspectives on Soil Salinization in Mirab Abaya District, Gamo Zone, Southern Ethiopia

Irrigation and Drainage, EarlyView.
ABSTRACT Soil salinization is a critical threat, impacting 20% of the world's irrigated lands and jeopardizing food security. In Ethiopia's Mirab Abaya district of the Gamo Zone, unsustainable irrigation methods exacerbate this issue. This paper examines local farmers' soil–water management systems and their awareness of salinization, aiming to educate

Agricultural watershed modeling: a review for hydrology and soil erosion processes

Ciência e Agrotecnologia, 2016
Models have been used by man for thousands of years to control his environment in a favorable way to better human living conditions. The use of hydrologic models has been a widely effective tool in order to support decision makers dealing with watersheds

Evapotranspiration Estimation and Irrigation Performance Assessment Using Remote Sensing: A Case Study of the Ergani Dam Irrigation System (Turkey)

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient water resource management is critical for sustainable agriculture, with evapotranspiration (ET) serving as a key parameter. Remote sensing (RS) techniques offer cost‐effective approaches for ET estimation and irrigation performance assessment in extensive agricultural systems.

Maize Yield, Water Productivity and Economic Analysis Under Different Irrigation and Nitrogen Management Strategies Using Field Data and CERES‐Maize Model

Irrigation and Drainage, EarlyView.
ABSTRACT There is limited integrated evaluation of nitrogen (N) and irrigation management strategies for improving maize yield and productivity using crop models. The effects of N and irrigation on maize yield and productivity under centre pivot (CPI) and subsurface drip irrigation (SDI) using the CERES‐Maize model were investigated. N treatments were (

Hydrological Factors for Phosphorus Transfer from Agricultural Soils

, 1999
Understanding and managing against phosphorus (P) transfer from agricultural soils to receiving waters is a multidisciplinary task in which the role of hydrology is particularly difficult to simplify. We review current knowledge to define the spatial and temporal controls on P transfer from agricultural soils via the various hydrological pathways ...
