Agriculture Data

AgProdCereals

Cereals production in China's subnational model is made up of data from two sources that have been blended together. The data from 1949-2003 came from the China Data Center database table 804 and the data from 2004-2015 came from the China Statistical Yearbooks 2005-2016 in Chapter 12 Agriculture table 10 Output of Major Farm Products. These two sources blend together to generate a continuous series with data from 1949-2015, one of the longest time series in the China subnational model. This data was converted into million metric tons from  ten thousand metric tons. 

AgProdFruitsExclMelons

Fruit production in China's subnational model came from the China Data Center database table 804. This series runs from 1949-2003. The data was converted from ten thousand metric tons to million metric tons before importing into IFs. 

This series is outdated and could be updated with data that is available through the China Statistical Yearbooks in Chapter 12 Agriculture table 10 Output of Major Farm Products. This series is available from 2004-2015 and would give the model more recent data for initialization and improved model performance. 

AgProdMeat

Meat production in China's provinces was found in the China Data Center database in table 804 and this data was blended with data that was found in previous iterations of this model from the China Statistical Yearbooks 2006. The data was converted from ten thousand metric tons to million metric tons. The two series gives a final data series of 1949-2003, and 2005. 

This series is outdated and could be updated with data that is available through the China Statistical Yearbooks in Chapter 12 Agriculture table 14 Output of Livestock Products. Through the China Statistical Yearbooks 2005-2016 there is sufficient coverage to have a time series from 1949-2015. The DataPlanet database in table 271 also has data available for meat production from 1949-2013. 

LandAgri

Agricultural land is one of the first series that was included in the China subnational model using data from the China Statistical Yearbooks 2006 from Chapter 12 Environment Protection table 18 Land Use by Region. This series only has one year of data, 2005. The data is in thousand hectares and normalized to national data using ApplyMultAll.

This series could be updated with more recent data from the China Statistical Yearbooks 2007-2016 in Chapter 8 Resources and Environment table 24 Land Use by Region. An update would allow for the series to run from 2005-2015. 

LandArea

Land area was found in the China Statistical Yearbooks 2006. This data was converted into million hectares from ten thousand hectares. Although there was only one observation for 2005 found, the observations were repeated through 2013 to improve model performance. 

LandCrop

Crop land was found in the China Statistical Yearbooks 2006 in chapter 13 Agriculture table 15 Total Sown Area of Crops. This data is in thousand hectares and ApplyMultAll is used to normalize the data into the correct units.
