Future pathways or scenarios depend on the assumed projections of key driving forces. Thus, all results can only be understood and interpreted in the context of the assumed future environment in which they unfold. | Future pathways or scenarios depend on the assumed projections of key driving forces.

As a result of the exogenous drivers, IMAGE projects how human activities would develop in the Human system, namely in the energy and agricultural systems (see [[IMAGE framework | As a result of the exogenous drivers, IMAGE projects how human activities would develop in the Human system, namely in the energy and agricultural systems (see [[IMAGE framework schematic]]). Human activities and associated demand for ecosystem services are squared to the Earth system through the ‘interconnectors’ Land Cover and Land Use, and Emissions (see [[IMAGE framework schematic]]). | ||
Assumed policy interventions lead to model responses, taking into account all internal interactions and feedback. Impacts in various forms arise either directly from the model, for example the extent of future land-use for agriculture and forestry, or the average global temperature increase up to 2050. Other indicators are generated by activating additional models that use output from the core IMAGE model, together with other assumptions to estimate the effects, for example, biodiversity (GLOBIO; see Components [[Terrestrial biodiversity]] and [[Aquatic biodiversity]]) and [[flood risks]]. | Assumed policy interventions lead to model responses, taking into account all internal interactions and feedback.
