The goal of the master thesis is to reveal which factors are hindering implementation of the urban renewal in Slovenia. These factors were analyzed on the basis of the problem analysis in the case of brownfields in the Municipality of Trbovlje. Problem analysis of urban renewal has been designed based on the study of literature and survey of Slovenian experts in the field of spatial planning. Problem analysis consists of three-set inquiry: (1) comparative analysis of German and Slovenian legislating on urban renewal, (2) the analysis of the economic-development potential of the statistical region Zasavje and (3) the analysis of the characteristics of selected brownfields in the municipality of Trbovlje. For each analytical set, a set of factors that can significantly affect the implementation of urban renewal measures had been selected, and attribute indicators which served as the basis for the procedure of problem analysis, were defined.
It was discovered that characteristics of the investigated brownfields in the Municipality of Trbovlje are limiting the renewal process and that statistical region of Zasavje is economically strongly disadvantaged. In such, lagging behind regions, urban renewal initiatives are difficult to carry out. Further more, the legislative framework does not provide efficient measures. These instruments are not accommodated nor to the implementation of the renewal in the lagging behind region nor are they suitable for the brownfields. Therefore, the conclusion consists of the proposal for the improvements of the approach to the renewal in Slovenia. For example, strategic approach to the urban renewal should offer the criteria for the establishment of the local or regional GIS of internal land potentials, define the scientific basis for the decision making and argumentation of the locally tailored measures of the urban renewal and the techniques of integrating the public into the planning process. Implementation of the projects should be supported by financial sources, co-ordination and supervision of the urban renewal delivery.
