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.
