Current political and scientific debates are focused on finding a long-term policy beneficial both for environment and economy in rural areas in the EU member states. The proposed research project aims to methodologically reinforce these efforts and to contribute to development of an integrated policy for decision-making support in rural areas in an interdisciplinary process. The objective of the research is to develop a methodological framework integrating uncertain economic and ecological aspects in multiobjective decision-support systems in agricultural and environmental policies for Germany, Poland, and the U.S. Several analyses have been undertaken on multicriteria decision-making approaches and the problems of uncertainty in the European Union in different disciplines. However, most of them are focused on illustrating relations between them and comparing them. With the proposed research, the existing uncertainties will be directly incorporated in decision-support systems while uncertain and fuzzy information provided by experts will be firstly operationalised by means of the PROMETHEE approach. In order to progressively evaluate political problems an integrative programming model will be constructed to integrate fuzzy information as well as game theory to consider interactive decision-making between political stakeholders. The project will provide a novel, original and sustainable scientific tool for practical implementation to improve policy evaluation and design and to alleviate interactive decision-making processes in rural areas in the European countries. Thereby, an existing scientific gap in policy evaluation and in supporting political decision-making processes in rural areas in Europe can be filled, improving European scientific competitiveness and excellence in the researched field. The fellowship will be pivotal for the scientific progress of the researcher, reaching professional maturity and for preparing for the independent scientific career.
