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.

USE CONSTRAINTS

Data Policy by Data Provider

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

Data Policy for Project

Data Integration and Analysis System

The terms of data use of data providers take first priority over the DIAS data usage policy. In the event a data provider has not established terms of use, the following DIAS project data terms of use apply.

1. Users shall prioritize and abide by terms of use stipulated by a data provider in the event such exist

2. The use of DIAS data sets is limited to research and educational purposes [*1]

3. Users shall not modify the content of DIAS data sets

4. Users shall not provide the content of DIAS data sets to third parties

5. In the event of using DIAS data sets in an academic presentation, paper, article, or report, etc., users shall cite in parenthesis the text given as the data citation

6. In the event of using DIAS data sets in an academic presentation, paper, article, or report, etc., users shall submit a copy of the work (an offprint in the case of a paper, or a copy of the lecture summary in the case of an oral or poster presentation) to the DIAS office below

[*1] Data sets whose commercial usage are allowed under the data policy by data provider will be also allowed to be used commercially as DIAS data sets, after ongoing preparation works have been completed. Please contact the DIAS Office for more details.
