The paper addresses the issue of the constraint function and its use in methods of regional taxonomy and assessment of regional systems. It proposes an alternative definition for the constraint function for rule-based methods of functional regionalisation, such as the delineation of local labour-market areas, including alternative conceptions of the self-containment of the regions, and the trade-off between size and self-containment. An alternative constraint function has been applied in the territory of the Czech Republic as shown in the paper's illustrative example of its use from the original CURDS algorithm.

Abstract

This article deals with the issue of brownfi eld redevelopment for the needs of solar energy projects from diff erent perspectives. Attention is fi rst paid to a brief characterisation of the data and information available both for brownfi elds and for solar energy projects in the Czech Republic. Then there is description from the most important results of GIS analysis, which (based on a comparison of aerial images from diff erent years) identifi ed the previous uses at the 127 solar power plants with an output of over 1 MWp in the South Moravian Region. The results of the quantitative analyses are accompanied by knowledge from a qualitative survey conducted on selected actors participating in this kind of brownfi eld regeneration for solar energy development. The conclusion contains proposals which could contribute to the more intensive future use of brownfi elds for the needs of solar energy in the Czech Republic (a similar process to what has already successfully been realised in Germany). The research results can be inspiring not only for the Czech Republic but also for other EU-member counrties where brownfi elds have not been re-used for the needs of solar energy projects or where brownfi elds have been used in this way only marginally.
