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 |
| 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 | \(10^6 tDM/yr\) |
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.
