finalized the grazing grassland approach where the prod_level is now selected based on the potential and the current grazing intensity. Current is based on EUROSTAT grazing intensity. While the maximum is based on the stocking rate with the highest yields  per zone.

Food supply, protein supply and imporrt export are adjusted to work with the bulk downloaded input file from FAOSTAT.

In model data script: worked on newly discussed Import export approach where we substrat the non food and stocks from the import to get more realistic results .In progress.
In grassland: the stocking rate approach is implemented where we have potential (highest) and realistic stocking rates expressed in LSU/ha (0-2)

Grassland (stocking density change not yet done) and  model data update (processing sheet update with JD)

Worked on the whole script, focus on integrating the food groups and created new baseline sheets for import export and food supply.

Name convention was used: for for forage products. in for procin. 1 for forage crops. 1-DM for grassy crops. Ollies data was used when no values in tcf fao document.

adding all the different csv and some selected excel files. Now the model data scrip can be run with the available data sets here.

20 processing consistency

See merge request !2

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.
