On the derelict industrial plant in Brackwede, which was independent until 1973, a large leisure facility with an extensive range of leisure activities was planned. However, due to more recent findings, this direction was rejected and a natural green corridor was created with unique biotope areas that had developed over time from the abandoned bleaching ponds and meadows. The Luttertal is located in Bielefeld Quelle, south of the The industrial plant in Brackwede was intentionally abandoned since 1973, due to the local municipality recently cancelled the project of the redevelopment of the area and kept it intact. Till now, a “natural green area developed with very interesting biotope areas, which had evolved over time” at the abandoned site.

Overview

Nature-based solution

  • Parks and urban forests
  • Green corridors and green belts
  • Blue infrastructure
  • Lakes/ponds
  • Rivers/streams/canals/estuaries

Key challenges

  • Green space, habitats and biodiversity (SDG 15)
  • Habitat and biodiversity restoration
  • Green space creation and/or management
  • Regeneration, land-use and urban development
  • Conversion of former industrial areas
  • Promotion of naturalistic urban landscape design
  • Health and well-being (SDG 3)
  • Creation of opportunities for relaxation and recreation

Focus

Creation of new green areas, Ecological restoration of degraded ecosystems, Transformation of previously derelict areas, Management of rivers and other blue areas

Project objectives

1. Creation of diverse biotopes on the territory of the former industrial site (1); 2. Increase of the biodiversity of the area (1).

Implementation activities

The city of Bielefeld declined the project of construction of the shopping center at the place of the former industrial production and let it develop naturally (1). Until the 20th century wastewater coming from industrial activities was discharged to the ponds of the Luttertal in Brackwede. After the industrial activities were discontinued nature conquered back the area, while the contamination of the ponds continued due to untreated domestic waste water discharge. Following some civil protests against the pollution of the water, numerous discharges were discontinued in the following period and today the Lutter has a water quality II to II-III again, so it is only moderately polluted.

Details on the roles of the organisations involved in the project

Project implemented in response to ...

... an EU policy or strategy? Unknown
... a national policy or strategy? Unknown
... a local policy or strategy? Unknown (The intervention was implemented according to a decision of the Bielefeld city government from 1973, however without any supporting regulations (1). According to the later regulations analysed, the notion of the "derelict area" started to be conceptualized as a space with positive environmental impact only in the 1990s. Accordingly, this initiative can be considered as a unique example of the early positive evaluations of the derelict sites in Bielefeld.)
