This reverts commit 735c7aa3

currently the parts that are copied to script 'combine_crop_grass.R' are still active but should not be used anymore. Only first part is relevant and meant to be in this script on long term

I added some second level stages to crops

package loading

one stage processing sheet is done. But now it needs to be extended to multi stage. Also the human nutrition sheet can be derived from nevo automatically as well as the human nutrition sheet from cvb.

checking the push

First draft processing sheet done. Human nutrition sheet start mapping with nevo data sheet.

Development of database. Cropdatasets for EU28 almost finalized. Some minor adjustments still needed. Grassland still under development.

Fixed the suitability bug. Now current and suitable forage grass and forage crop are having the same yields.

Did some validation. Still there is something weird with the forage crops. They should be identical to the current yield per country but they are not. Often in the suitability yield dataset they are less. Don't know why yet...

Finalized the validation of the EU28 dataset with bar charts and summary tables.

Did some debugging, removed very small numbers in area and production and did some validation (visual, summary)

Created an R script for manipulating the GHG EFs and to adjust them to the new zones

Created a new folder with R script to calculate NP contents in R for forage crops from Nutrient tool database https://plantsorig.sc.egov.usda.gov/npk/main

external function script

Added the suitability crops to the excel > use the distinct crop list -> the other is not updated with suitability crops.

Creating a dataset with rangeland, arable land, arable pasture, natural pasture per zone (adm0, aez, soilagri). draft, not finished.

Final dataset for the globe and for EU28. Also cifos crop names are added. Issues are the not available disaggregation and the impication on nutrient intake (Rest, tnut, Veggie). Which nutrient content should be taken as a proxy?

all crops done. treenuts, veggies, EU subsetting. Function R script created. Suitability file created and transformed, linked to zones AEZ ADM0 Soilagri.

New zonation based on ADM0 - AEZ - DOMSOIL_IPCC(mineral and Organic) - Validation with EUROSTAT and FAO. Data transformation. Different types of agricultural land extractions
