This paper provides a comprehensive review of literature related to the assessment of climate change impacts on crop productivity using climate, water and crop yield models. The existing studies present that climate change models with higher spatial resolution can be a way forward for future climate projections. Meanwhile, stochastic projections of more than one climate model are necessary for ...

pressurized irrigation technologies of course have the potential to raise the productivity of land and water; but, these technologies could not popularize among the smallholders who own millions of farms worldwide. in developing pressurized irrigation technologies, particularly for field crops irrigation, researchers and manufacturers have developed more specialized and expensive technologies w...

Abstract Weather index insurance (WII) has been a promising innovation that protects smallholder farmers against drought risks and provides resilience adverse rainfall conditions. However, the uptake of WII hampered by high spatial intraseasonal basis risk. To minimize risk, standard approaches to designing based on seasonal cumulative have shown be ineffective in some cases because they do not...

High water consumption and inefficient irrigation management in the agriculture sector of middle lower reaches Amu Darya River Basin (ADRB) have significantly influenced gradual shrinking Aral Sea its ecosystem. In this study, we investigated crop growing seasons requirement for different types ADRB during 2004–2017. We applied FAO Penman-Monteith method to estimate reference evapotranspiration...

abstract in order to estimate the reference evapotranspiration different equation is used. validity of each methods depends upon the climate and the parameters which are used in these equations. therefore it is necessary to calibrate these methods for any specific area and for any desired frequency. in this study common temperature and radiation based methods were used for calculating crop evap...

the growth and development of crop models such as aquacrop model is the most important tools for decision-making and predicting crop yields. the aim of this research was to assess aquacrop model for simulating spatial variability of forage maize yield along the furrow. four treatments for calibration and validation of the model were investigated based on the percentage of supplied crop water re...

While climate change impacts on crop yields has been extensively studied, estimating the impact of water shortages on irrigated crop yields is challenging because the water resources management system is complex. To investigate this issue, we integrate a crop yield reduction module and a water resources model into the MIT Integrated Global System Modeling framework, an integrated assessment mod...
