- Agricultural area - grid (Total area for crop production (annual and perennial) and intensive grassland., type: model (from/to model))
- Biodiversity Intactness Index (BII) – grid (The average abundance across a set of species in each area relative to their reference population, which would be populations before any humans impacts but are usually populations in the least impacted settings available, type: model (from/to model))
- Bioenergy area (Area of bioenergy crop production, in model setting where sustainability criteria require that the area for bioenergy crops is not included in the agricultural production area (to avoid competition between bioenergy and food)., type: model (from/to model))
- Built-up area - grid (Urban built-up area per grid cell, excluded from all biophysical modelling in IMAGE, increasing over time as a function of urban population and a country- and scenario-specific urban density curve., type: driver)
- Carbon pools in soil and timber - grid (Carbon biomass in three soil pools (litter, humus and charcoal) and two timber pools (slow decaying, and fast decaying)., type: model (from/to model))
- Carbon pools in vegetation - grid (Carbon pools in leaves, stems, branches and roots)., type: model (from/to model))
- Carbon price (Carbon price on the international trading market (in USD in 2005 per tonne C-eq) calculated from aggregated regional permit demand and supply curves derived from marginal abatement costs., type: model (from/to model))
- Change in soil properties - grid (Change in soil properties, such as clay/sand content, organic carbon content, soil depth (topsoil/subsoil)., type: model (from/to model))
- Crop fraction in agricultural area - grid (Fraction of agricultural land by crop type, per grid cell., type: model (from/to model))
- Degraded forest area (Permanently deforested areas for reasons other than expansion of agricultural land (calibrated to FAO deforestation statistics)., type: model (from/to model))
- Energy resources (Volume of energy resource per carrier, region and supply cost class (determines depletion dynamics)., type: driver)
- Extensive grassland area - grid (Extensive pasture with low productivity used for grazing., type: model (from/to model))
- Forest management type - grid (Forest management type: clear cut, selective logging, forest plantation or additional deforestation., type: model (from/to model))
- GDP per capita (Gross Domestic Product per capita, measured as the market value of all goods and services produced in a region in a year, and is used in the IMAGE framework as a generic indicator of economic activity., type: driver)
- Harvested wood (Wood harvested and removed., type: model (from/to model))
- Intensive grassland area (Intensively used grassland areas for grazing or mowing, at locations also suitable for crop production., type: model (from/to model))
- Irrigation water withdrawal - grid (Water withdrawn for irrigation, not necessarily equal to the withdrawal demand, because of limited water availability in rivers, lakes, reservoirs and other sources., type: model (from/to model))
- Land supply for bioenergy - grid (Land available for sustainable bioenergy production (abandoned agricultural land and non-forested land)., type: model (from/to model))
- Lifestyle parameters (Lifestyle parameters influence the relationship between economic activities and demand for energy., type: driver)
- MSA (mean species abundance) - grid (Mean Species Abundance (MSA) relative to the natural state of original species., type: model (from/to model))
- Management intensity crops (Management intensity crops, expressing actual yield level compared to potential yield. While potential yield is calculated for each grid cell, this parameter is expressed at the regional level. This parameter is based on data and exogenous assumptions - current practice and technological change in agriculture - and is endogenously adapted in the agro-economic model., type: model (from/to model))
- Management intensity livestock (Management intensity of livestock, expressed at the regional level. This parameter is based on data and exogenous assumptions, i.e. current practice and technological change in livestock sectors, and is endogenously adapted within the Agricultural economy component., type: model (from/to model))
- NPP (net primary production) - grid (CO2 sequestered by plants and incorporated in new tissue in plant carbon pools., type: model (from/to model))
- Population (Number of people per region., type: driver)
- Potential natural vegetation - grid (Potential natural vegetation type/biome, based on distribution of plant functional types., type: model (from/to model))
- Private consumption (Private consumption reflects expenditure on private household consumption. It is used in IMAGE as a driver of energy., type: driver)
- Protected area - grid (Map of protected nature areas, limiting use of this area., type: driver)
- Regrowth forest area - grid (Areas of re-growing forests after agricultural abandonment or timber harvest., type: model (from/to model))
- Sector value added (Value Added for economic sectors: Industry (IVA), Services (SVA) and Agriculture (AVA). These variables are used in IMAGE to indicate economic activity., type: driver)
- Technology development of energy conversion (Learning curves and exogenous learning that determine technology development., type: driver)
- Technology development of energy supply (Learning curves and exogenous learning that determine technology development., type: driver)
- Water withdrawal other sectors - grid (Total annual and monthly water withdrawal for households, industry and electricity. Not necessarily equal to the withdrawal demand, due to limited water availability., type: model (from/to model))
