As the Thuringian State Development Corporation, we record brownfield sites and abandoned buildings in a dedicated register. Our aim is to repurpose these areas and counteract the sealing of valuable green spaces and usable land.
The sight of old buildings from a bygone era sets off an unstoppable stream of ideas in our minds: a wild web of thoughts begins to form, imagining what once was here and what might be again, with the right idea, a suitable partner, and the necessary vision. Since December 2004, we have been recording abandoned buildings and derelict land in our brownfield register, for which no one (anymore) feels responsible. Since 2017, this register has been available online in a GIS-based format.
A pool for derelict land
Because Thuringia has a number of old, unused, or derelict sites, the idea arose to record them in an interactive database on behalf of the state of Thuringia. This not only identifies the potential of these areas but also (re)initiates processes that make their reuse tangible. The brownfield register primarily records areas of 3,000 square meters or larger that are wholly or partially built upon or sealed, and whose existing structures exhibit visually identifiable defects. Furthermore, the database lists properties that have not been used for an extended period, are only used to a minor extent, or for which there is no concrete plan for future use. Among the approximately 1,200 entries currently included are former industrial sites, former military or agricultural facilities, and even a former agricultural airfield.
Why all the work?
It's easy to simply abandon derelict land and properties and build urgently needed industrial or residential sites elsewhere. However, this leads to increased land consumption, especially of agricultural land. And it is precisely this consumption that we aim to curb with the brownfield register.
Investors from around the world, developers, real estate companies, and we as the state development corporation are developing residential, industrial, and commercial areas in Thuringia to meet local demand. Furthermore, Thuringia's transport infrastructure still has gaps – the Federal Transport Infrastructure Plan 2030 alone envisions over 30 projects for the state, such as the construction of bypasses. Implementing these projects inevitably involves encroaching on established natural areas. By law, each of these encroachments must be compensated for. To effectively target such measures to unused or fallow land, knowledge of the location and size of brownfield sites is essential. With our brownfield register, we are therefore contributing to the identification of unused land and its return to the land cycle – enabling its reuse or renaturalization.
Please keep your eyes peeled: Report any fallow land in your area to us and contribute to sustainable land use. After careful review, we will gladly add it to our database
