4.2 Step 2: computation of the targeted livestock production (original) (raw)
Worksheets in the FABLE Calculator:
⇒ 2_calc_livestock
⇒ 2_data_livestock
The computation of the production from the livestock sector is the second step in the FABLE Calculator. The livestock sector supplies animal food products (cf. Appendix 1) and consumes other agricultural products for animal feed. This explains why we need to compute the production of the livestock sector before the production of the crop sector. The objective of this calculation step is to compute the evolution of the livestock herd which then determines the feed demand and the pasture area which are used in the calculation steps that follow.
Figure 8. Computation of the targeted livestock herd, feed demand, and pasture area
Note: When an arrow passes through a box or is sourced from more than one, it means that two parameters are used together in order to compute the next parameter e.g. historical exports times export shifter equals to the targeted exports. The numbers within the blue hexagons refer to the scenario table numbers in the worksheet Scenarios Selection, as labeled in the Open FABLE Calculator 2020 (e.g. 5 for Table S.5). The numbers may differ in other versions of the FABLE Calculator.
