Intra‐Seasonal Crop Management and the Potential Benefit of Seasonal Precipitation Forecasts: Farm‐Level Embedded Risk Analysis in Ethiopia

Journal of Agricultural Economics, EarlyView.
ABSTRACT How large is the potential benefit for farmers from obtaining forecasts of total rainfall in the upcoming season? This critically depends on the local farm system and the crop management actions available to farmers to respond to the forecasts issued. Studies assessing the financial value of seasonal precipitation forecasts have so far focused

A Regional Version of the Aquacrop Model Evaluated with Satellite Retrievals and Backscatter Data

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The current intensive use of agricultural land forces a shift to more sustainable methods of crop production. Future crop demands are expected to rise due to a strong increase in population and prosperity, and the uncertainty in crop yields is expected to increase because of changing climatic conditions.

Modeling Irrigation Efficiency Paradox From Farmers' Behaviors

Earth's Future, Volume 14, Issue 6, June 2026.
Abstract Agricultural irrigation accounts for 70% of global freshwater withdrawals, highlighting its critical role in water conservation. However, numerous studies have presented the irrigation efficiency paradox, whereby increased efficiency rarely reduces water consumption.

AquaCrop Simulation of Winter Wheat under Different N Management Practices [PDF]

, 2022
AquaCrop is a well-known water-oriented crop model. The model has been often used to simulate various crops and the water balance in the field under different irrigation treatments, but studies that relate AquaCrop to fertilization are rare.

Fielding Floods for Flourishing Farms: A Framework for Assessing the Reuse of Small Flood Reservoirs as Irrigation Reservoirs

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Due to the increased intensity and frequency of droughts under a warming world, agricultural irrigation demand (AID) is likely to increase in many regions of the world—not just in semi‐arid and arid regions, but also in temperate regions. Small reservoirs have often been touted as a decentralized solution to increase water supply resilience ...

Sensitivity Analysis of Aquacrop Model for Barley in Pakdasht Region [PDF]

علوم آب و خاک, 2019
In recent years, a lot of research has been done on the Aquacrop model, the results show that this model simulates the product performance for deficit irrigation conditions. But this model, like other models, is sensitive to values of independent variables (model inputs).

Estimation of Actual Evapotranspiration, Water productivity, and Irrigation Efficiency of Wheat Fields in Surface and Sprinkler Irrigation Systems Using Remote Sensing

علوم آب و خاک, 2022
In arid and semi-arid regions, water resource management and optimization of applying irrigation water are particularly important. For optimization of applying irrigation water, the estimated values of actual evapotranspiration are necessary for avoiding

Irrigation Water Management for Wheat Using Aquacrop Model إدارة میاه الری الحقلی للقمح باستخدام نموذج AquaCrop

Journal of Soil Sciences and Agricultural Engineering, 2020
The study aimed to evaluate the performance of the Food and Agriculture Organization "AquaCrop" model (version 6.1) in simulating the productivity and biomass of wheat crops in old lands under the surface irrigation system. Field data for the period from 2013- 2016 were used to calibrate the model's through matching productivity and biomass observed ...

Assessing Response of Water Footprint of Maize Production to Drought in China: Different Climate Scenarios and Irrigation Strategies

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Climate change impacts on water resources and drought characteristics will significantly affect regional agricultural water security. To clarify the response mechanism of water consumption and drought, this study coupled meteorological data from CMIP6 under two shared socioeconomic pathways in China.
