How good is good enough? Data requirements for reliable crop yield simulations and yield-gap analysis

Autor: Grassini, Patricio Bussel, Lenny G. J. van Wart, Justin van Wolf, Joost Claessens, Lieven Yang, Haishun Boogaard, H. Groot, Hugo de Ittersum, Martin K. van Cassman, Kenneth G.

Numerous studies have been published during the past two decades that use simulation models to assess crop yield gaps (quantified as the difference between potential and actual farm yields), impact of climate change on future crop yields, and land-use change. However, there is a wide range in qua...

From field to atlas: Upscaling of location-specific yield gap estimates

Autor: Bussel, Lenny G. J. van Grassini, Patricio Wart, Justin van Wolf, Joost Claessens, Lieven Yang, Haishun Boogaard, H. Groot, Hugo de Saito, Kazuki Cassman, Kenneth G. Ittersum, Martin K. van

Accurate estimation of yield gaps is only possible for locations where high quality local data are available, which are, however, lacking in many regions of the world. The challenge is how yield gap estimates based on location-specific input data can be used to obtain yield gap estimates for larg...
