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 Comparative Study of Potential Evapotranspiration Estimation by Three Methods with FAO Penman–Monteith Method across Sri Lanka [PDF]

, 2022
Among numerous methods that have been developed to estimate potential evapotranspiration (PET), the Food and Agricultural Organization Penman–Monteith model (FAO P–M) is often recognized as a standard method to estimate PET.

Estimation of Reference Evapotranspiration using the FAO Penman-Monteith Method for Climatic Conditions of Poland

, 2011
Evapotranspiration is the combination of soil evaporation and crop transpiration. Weather parameters, crop characteristics, management and environmental factors affect evapotranspiration. Reference, potential and actual evapotranspiration are distinguished. These terms are commonly used, although some differences of their definitions can be found among

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.

A microcontroller - Based Irrigation Scheduling Using FAO Penman-Monteith Equation

Turkish Journal of Agricultural Engineering Research, 2023
This study uses the Food and Agricultural Organization (FAO) Penman-Monteith equation to develop a crop water algorithm needed to automate the supply of specific amount of water to crops, depending on their different crop water requirements. This was done to deviate from the practice of supplying the same amount of water to different crops during ...

Projections of Meteorological Drought and Potential Evapotranspiration Using the RegCM4 Over Northeastern Iran

International Journal of Climatology, EarlyView.
We downscale CanESM2 with the Regional Climate Model version 4 (20 km) and evaluate against 15 stations to derive monthly PET (Hargreaves–Samani) and SPEI for northeastern Iran (1990–2009, 2040–2059, 2080–2099). Results show robust PET increases and a shift toward more negative monthly SPEI—especially April–September—indicating earlier onset and longer
