The various modules of IMAGE 3.0 for the socio-economic and the earth system, as described in the previous chapters, are closely coupled and linked via multiple feedback mechanisms, and therefore form the “core model” of IMAGE 3.0. These modules typically produce two types of output. One to serve as input for other parts of IMAGE, the second to describe impacts in the form of end-indicators in their own right. In practice many indicators do serve both purposes, and many state variables of the IMAGE core modules are interesting as impact indicators, like land use change, crop yields or climate parameters. Over time interest developed among researchers and policy analysts to expand the list of impacts beyond what the core model can provide. As a result, a suite of additional impact modules was developed and linked with the IMAGE core model through a static exchange of data. In other words: those impact modules can be invoked if and when desired to address specific fields of interest, and proved very helpful to explore interactions between very different issues of sustainable development.

Description of Impacts

IMAGE 3.0 modules for the Human system and Earth system are closely linked via multiple feedback mechanisms to form the core model of IMAGE 3.0. These modules produce output for two types of purposes. One purpose is to serve as input for other IMAGE modules and the other purpose is to serves as indicator for impacts. Many outputs serve both purposes, and many state variables of the IMAGE core modules constitute interesting impact indicators, such as land-use change, crop yields and climate parameters.

The range of impacts has been extended beyond those that the core model can provide. As a result, additional impact modules have been developed and linked to the IMAGE core model through static data exchange. These impact modules can be used to address specific interests, and have been used in exploring a broad range of interactions between issues in sustainable development (see Dataflow_overview and Variable overview).

A wide range of impact indicators originate from the modules in the core IMAGE model and those often reported in assessment studies are:

Further impact components available in the IMAGE 3.0 framework include Terrestrial and Aquatic biodiversity, Flood risks, Land degradation, Ecosystem services, and Human development.
