LIAISE News Bulletin - 9th Issue


As the European Commission and the Member States prepare for policies to increase the efficiency of the natural resources use, some of the LIAISE partners are exploring potentials for modelling the impacts of such policies on the various aspects of sustainable development. The LIAISE concept of a Reference Model for Impact Assessment Tools (RM-IAT) is at the core of these activities. The RM-IAT is developed (a) to safeguard minimum quality standards for IA tools with respect to testing, modelling approaches, documentation, calibration sets, input data sets etc., and (b) to collect information on behalf of the possible users with respect to objectives and characteristics of IA tools, input and output data, sorts of studies that can be performed, required investments to apply the tool, etc. The second aim is to describe models from a more software engineering and technical viewpoint in the sense that this information will help in linking models to other models and available data. These models and data can be the work of modeller teams and researchers beyond the LIAISE Consortium. Finally, the RM-IAT can be of help to systematically identify gaps and missing aspects that are not covered by current models. A requirement analysis will define to which extent these missing aspects should be investigated and dealt with in order to be able to do further model improvement. Presently, the RM-IAT is being used not only for integrated environmental-economic models for the assessment of resource efficiency policies, but also to support the integration of different models for the assessment of the reformed EU common agricultural policies.  If you want to learn more about this work, you are invited to contact the LIAISE teams that are involved in this research (
