Abstract: This paper describes an update to the tool developed by Blanc (2017b) which allows users to calculate emulated rainfed crop yields projections for four crops and five different global gridded crop models (GGCMs) at the regional level. This updated tool allows users to also estimate irrigated crop yields and corresponding irrigation water requirements under user-given climate change scenarios. As with the previous version, users must be careful when selecting scenarios and ensure that they are within the range of the climate change scenarios used to estimate the response functions in Blanc (2017) and Blanc (2020).
