Integrated Impact Analysis Tool

An integrated Impact Analysis Tool for assessing impacts of urbanisation in Europe (IIAT-EU) and European urban regions (IIAT-region).

How might Climate Change affect land uses in the urban-rural interface? What might be future pressures of peri-urbanisation? How will economy, social cohesion and landscapes develop in response to urban growth? What about biodiversity and ecosystem services? How is the sustainability performance of the region I am living in, compared to neighbouring regions, or to regions that are similar in profile?

The European integrated Impact Analysis Tool (iIAT-EU) represents a novel interface between science and policy-making contributing to further knowledge on impacts of future urbanisation in Europe. The application principles, the functionality and the graphical user interface of the iIAT-EU have been developed in narrow collaboration with planners, administration, policy makers and stakeholders. Combining thematical broadness of projections with spatial flexibility is the new quality of the iIAT –EU, facilitating knowledge integration for discussions and decision making towards sustainable solutions for urban-rural relationships.


The iIAT‐Region approach, technically similar to the iIAT‐EU, allows selecting regional land use related impact indicators, the case studies to be compared, and the scenarios that should form the basis of the comparison, as well as thresholds or target values for single indicators. Currently, the three European PLUREL case studies are included: Haaglanden (Netherlands), Koper (Slovenia) and Leipzig‐Halle (Germany).

The PLUREL iIAT is an internet‐accessible tool that displays results in form of spidergrams. Those spidergrams provide a surface that enables an easy and holistic perception of multilevel information. These spidergrams allow for a visualisation of changes in sustainability indicators, as positive or negative trends according to different scenarios are immediately visible as shifts in the lines of the spidergrams.
