Efforts are under way in the agricultural research for development community to employ crop growth simulation models for the ex"=ante assessment of the impacts of agricultural technologies, in particular improved crop varieties. The approach, dubbed ``virtual crop modelling'', consists in the man...

Virtual crop modeling for technology impact assessment - lessons from a potato crop growth model
This article examines how the estimated impacts of crop technologies vary with alternate methods and assumptions, and also discusses the implications of these differences for the design of studies to inform research prioritization. Drawing on international potato research, we show how foresight s...

Simulating cultivar variations in potato yields for contrasting environments.
Most analytic tools used in assessing gains from investments in agricultural research either fail to take into consideration environmental impacts or, if they do, it is at a very limited level. The CGIAR Research Programs adopt a systems approach and require a fully integrated consideration of bi...

Virtual crop modeling is the representation of future genetic improvements from plant breeding in crop growth simulation models through changes in genetic coefficients or other crop model parameters with the objective of analyzing ex-ante the impacts of improved traits on crop yields and assistin...
