The grid-cell yield data available in this dataset are estimated using the global gridded crop model CYGMA and the assumptions on future climate and socioeconomy. The Shared Socioeconomic Pathways (SSP) 1, 2 and 3 are used as the assumptions on socioeconomy. Four different Representative Concentration Pathways (RCP) are used to account for the CO2 fertilization effect on yields. Future climate conditions are based on the bias-corrected CMIP5 GCM outputs. The data for maize, rice, wheat and soybean for the period 1961-2100 are available at the 0.5-degree resolution. Only spring wheat is consisdered. The yield data are available for each of irrigated and rainfed conditions. Also the yield data are available for areas where currently cultivation is not conducted. This allows users to calculate national average yield using user's own irrigation scenarios.
