| Model driver group | Variable | -HasInputVar | Description |
|---|---|---|---|
| Technological change in agriculture and forestry | Harvest efficiency | Forest management | Fraction of harvested wood used as product, the remainder being left as residues. Specified per biomass pool and forestry management type. |
| Technological change in agriculture and forestry | Production system mix | Livestock systems Nutrients | Livestock production is distributed over two systems for dairy and beef production (intensive: mixed and industrial; extensive: pastoral grazing), and to three systems for pigs (backyard, intermediate, intensive) and poultry (backyard, boilers, laying hens) with specific intensities, rations and feed conversion ratios. |
| Technological change in agriculture and forestry | Irrigation project efficiency | Ratio of quantity of irrigation water required by the crop (based on soil moisture deficits) to the quantity withdrawn from rivers, lakes, reservoirs or other sources. This parameter is given at country level. | |
| Technological change in agriculture and forestry | Irrigation conveyance efficiency | Ratio of water supplied to the irrigated field to the quantity withdrawn from the water source, determining the quantity of water lost during transport. This parameter is defined at country level. | |
| Technological change in agriculture and forestry | Animal productivity | Livestock systems | Effective production of livestock commodities per animal per year. |
| Technological change in agriculture and forestry | Manure spreading fraction | Nutrients | Fraction of manure produced in staples that is spread on agricultural areas. |
| Technological change in agriculture and forestry | Livestock rations | Livestock systems Nutrients | Determines the feed requirements per feed type (food crops; crop residues; grass and fodder; animal products; scavenging), specified per animal type and production system (extensive/intensive/backyard/intermediate/intensive/broiler/laying hens). |
| Technological change in the energy system | Energy intensity parameters | Energy demand | Set of parameters determining the energy use per unit of economic activity (in absence of technical energy efficiency improvements). |
| Technological change in the energy system | Learning rate | Energy supply | Determines the rate of technology development in learning equations. |
| Technological change in the energy system | Energy efficiency technology | Energy demand | Model assumptions determining future development of energy efficiency. |
| Technological change in the energy system | Technology development of energy conversion | Energy supply and demand Energy conversion | Learning curves and exogenous learning that determine technology development. |
| Technological change in the energy system | Technology development of energy supply | Energy supply and demand Energy supply | Learning curves and exogenous learning that determine technology development. |
| Trade regimes, tariffs and barriers | Trade policy | Agricultural economy | Assumed changes in market and non-market instruments that influence trade flows, subject to WTO rules and country and region regulation. |
| Trade regimes, tariffs and barriers | Trade restriction | Energy supply | Trade tariffs and barriers limiting trade in energy carriers (in energy submodel). |
