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...

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...

The presentation addresses how reducing agricultural GHG emissions impacts food security, and what the trade-offs are. Presentation given by Stefan Frank at the European Geosciences Union conference on 24 April 2017.

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...
