DATASET OVERVIEW

Abstract

The grid-cell yield data available in this dataset are estimated using the global gridded crop model CYGMA and the assumptions on historical and non-warming climate conditions. The CO2 fertilization is considered when simulating yields under the historical climate condition. The climate inputs to the CYGMA model were derived from the historical and non-warming counterfactual climate simulations using the MRI-AGCM3.2 and used after bias-correction. The data for maize, rice, wheat and soybean for the period 1961-2010 are available at the 0.5-degree resolution. The unit of yield data is tonnes per hectare. 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.

DATA PROCESSING

Data Processing (1)

General Explanation of the data producer's knowledge about the lineage of a dataset

Yields under irrigated and rainfed conditions were computed and then averaged using the extent of irrigated and rainfed areas as the weights.

DATA POLICY

Data Policy by the Data Provider

Users are asked to cite the reference (Iizumi et al., 2018) when the dataset is used.
