### Agricultural production

#### Indicators:

| Production of animal products Production of food crops Production of pasture and fodder species | Production of wood products Production of biofuel crops |

Agricultural production shows the volumes of agricultural production and forestry. Agricultural production consists of animal products, food crops, pasture and fodder species, wood products and biofuel crops.

The underlying demand for agricultural and wood products, and biofuels, is covered under agricultural demand and agricultural trade, while the consequences for land requirements can be viewed under land use. The production systems for livestock production and feed are described under animal husbandry and land use, respectively. The treatment of forests after wood extraction is described in the land-cover model (LCM).

| #### Production of animal products
| unit:1000 Gg/yr (teragram fresh weight per year) dimension: region, animal product

This variable represents the total production of animal products (beef, milk, pork, mutton and goat meat, poultry and eggs) per region. Production of animal products is the sum of human consumption, the use as animal feed, and net export (+) or import (-). The production figures are used in the land-cover model to determine region-specific land-use patterns. The description of livestock production can be found under animal husbandry and land use.

It should be noted that the demand for 'affluent products', primarily animal products, is calculated by the agricultural economy model. However, the results for some individual products included in the affluent products group are also determined by the scenario assumptions on caloric intake. For South Asia this leads to a low fraction of beef and a high fraction poultry and pork. For North Africa and the Middle East this leads to a low fraction of pork.

| #### Production of food crops
| unit:1000 Gg/yr (teragram fresh weight per year) dimension: region, aggregated food crop

This variable describes the total production of seven aggregated food crops (temperate cereals, rice, maize, tropical cereals, pulses, root and tuber crops and oilcrops) per region. The production of food crops includes food crops for human consumption and animal feed, and is the sum of consumption of food crops and net export (+) or import (-). The calculated production of food crops is used in the land-cover model to determine region-specific land-use patterns. A brief description of the crop production in each region is given in land use.

It should be noted that the demand for food crops is a direct consequence of the agricultural economy model. However, the results for the intake of oilcrops are also determined by the scenario assumptions on caloric intake.

| #### Production of pasture and fodder species
| unit:1000 Gg/yr (teragram fresh weight per year) dimension: region, animal type

This variable actually describes the consumption of grass and fodder species per region. The actual grass production always exceeds the consumption, but is not explicitly modelled because yield data are not available.

The model assumes no trade in pasture and fodder species. The calculated use of grass and fodder species is used in the land-cover model to determine region-specific land-use patterns. The description of the demand for animal feed (including grass and fodder species) animal husbandry and production is described in land use.

| #### Production of wood products
| unit:1000 m3/yr (1000 cubic meters per year) dimension: region, wood product

The production of wood products, which equals demand, is calculated at the regional level in the agricultural economy model. Three categories of wood products are distinguished:

- pulpwood and particles (with a turnover or lifetime of 10 years)
- saw logs, veneer and other industrial round wood (turnover = 100 years)
- fuelwood and charcoal

The demand for fuel wood and charcoal is assumed to be a fixed fraction of the demand for traditional biofuels, as computed by the energy model (TIMER). The production of the other wood products is calculated on the basis of a statistical relationship between wood production, population growth, industry value added and the availability of forests. This relationship is based on historical data from the Food and Agriculture Organization of the United Nations (FAO). The wood volumes are converted to weights on the basis of conversion factors of FAO. The treatment of forests after wood extraction is described in the land-cover model.

| #### Production of biofuel crops
| unit:1000 Gg/yr (teragram per year*) dimension: region, biofuel crop *Fresh weight for sugar and maize, dry matter for woody and non-woody biofuel crops.

This variable represents the total regional production of modern biofuel crops (i.e., crops grown deliberately for the production of biofuels). Because the model assumes that there is no trade in unprocessed biofuel crops, the production of biofuel crops equals the consumption. Production figures are used in the land-cover model to determine region-specific land-use patterns. The description of the crop production in each region can be found under land use.
