Brownfield abandonment expressed by changes in land cover (1996-2012) - case study of Brno, Czech Republic

Popis výsledku v původním jazyce

Brownfields are sites previously used for numerous economic activities where the activity ceased to exist resulting in the abandonment of brownfields. This abandonment can be clearly seen in the state of individual sites expressed by deterioration of present buildings and slow vegetation succession on unsealed surface. The rate of abandonment can be easily captured by time series of aerial photographs. This contribution presents partial results of a project focusing on developing methodology for optimizing decision-making processes used in brownfield redevelopment. In particular, it focuses on changes in land cover in brownfields located in city of Brno, Czech Republic, that occurred between 1996 and 2012. In total, 124 brownfields have been identified and were classified according to their previous use: industrial, agricultural, military, railway, civic amenities, residential and other. Land cover changes were researched on the basis of orthophotos from three periods (1996, 2003, 2012) and we distinguished bare surfaces (without vegetation), surfaces with herb vegetation, woody vegetation, sealed surfaces, buildings, water and mixed surfaces. Results show that in 1996 buildings dominated with herb vegetation being the second most widespread surface. This corresponds with the fact that majority of brownfields was normally used. In 2003 surfaces with buildings and sealed surfaces decreased while bare surfaces increased; this period shows first marks of larger abandonment. Finally, 2012 reflects advanced brownfield abandonment expressed by increase in surfaces with both herb and woody vegetation. Regarding previous uses, railway, agricultural and residential brownfields displayed the highest rates of dynamic changes, while brownfields from civic amenities, other uses and industrial brownfields had the smallest dynamics.
