IMAGE is a comprehensive integrated modelling framework of interacting human and natural systems. Its design relies on intermediate complexity modelling, balancing level of detail to capture key processes and behaviour, and allowing for multiple runs to explore aspects of sensitivity and uncertainty of the complex, interlinked systems (see introduction page [[IMAGE_framework_introduction | IMAGE is a comprehensive integrated modelling framework of interacting human and natural systems.

While models are developed for different purposes, and thus have limited overlap in scope and detail, in practice many hybrid models are in use. As illustrated in Figure below, IAM models are between models with a primary focus on the Earth system (Earth System Models) and models that focus on the Human system such as pure economic models. | While models are developed for different purposes, and thus have limited overlap in scope and detail, in practice many hybrid models are in use.

Within the IAM group clearly different model groups exists, and IMAGE is characterised by relatively detailed biophysical processes and a wide range of environmental indicators. IMAGE 3.0 also includes an economic model to represent the agricultural system, and a process model to describe the energy system, but has less detail on economics and policy instruments than other energy models. In terms of application, many models are designed and used for climate policy analysis, such as [[FUND]] and [[DICE]], while other models address a broader range of issues. IMAGE was originally designed to assess the global effect of greenhouse gas emissions and now covers a broad range of environmental and sustainability issues. | Within the IAM group clearly different model groups exists, and IMAGE is characterised by relatively detailed biophysical processes and a wide range of environmental indicators.
