Description

The production module calculates regional production of MAgPIE commodities from cluster level production data.

  Description Unit A
fm_croparea
(t_all, j, w, kcr)
Different croparea type areas \(10^6 ha\) x
pm_yields_semi_calib
(j, kve, w)
Potential yields calibrated to FAO regional levels \(tDM/ha/yr\) x

Output

module outputs
  Description Unit
pm_prod_init
(j, kcr)
Production initialization for year 1995 \(tDM/yr\)
vm_prod
(j, k)
Production in each cell \(10^6 tDM/yr\)
vm_prod_reg
(i, kall)
Regional aggregated production \(10^6 tDM/yr\)

Realizations

(A) flexreg_apr16

This realization aggregates agricultural production from cluster level j to regional level i. Currently, cluster level production is available only for plant commodities, i.e for crops and pastures. Cluster level production of different crops and pasture is calculated in module [30_crop] and 31_past respectively.

\[\begin{multline*} vm\_prod\_reg(i2,k) = \sum_{cell(i2,j2)} vm\_prod(j2,k) \end{multline*}\]

The equation above describes regional production of a MAgPIE plant commodity vm_prod_reg as the sum of the cluster level production vm_prod of the same commodity.

Limitations For the time being, this approach is not applied to livestock products.
