IBA Internationale Bauausstellung has been for more than a century an important instrument of structural change in the regions facing socio-economic and environmental concerns. With the onset of Information Technology being used as a successful tool for urban planning, IBA now has reinvented itself as IBTA Internationale Bau und Technologieausstellung. It can be said that IBA and IBTA are constantly striving to have a forward-looking approach to global change in socio-economic, environmental and climatic systems. The IBA-Fürst-Pückler Land was an attempt to reimagine the postindustrial landscape of the open-cast lignite mining region in Lausitz or Lusatia which was completed in 2010. As part of the vision, several decommissioned and abandoned open-cast lignite mines were transformed into pit lakes, therefore becoming Europe’s largest artificial lake district. Two decades later the Rheinishce Revier or the Rhenish Mining Area (RMA), also an important Lignite region in Germany, is undergoing a similar process of change with plans to fill up the open cast mines with underground and river water to fulfil the vision of a Lake for the community. In the context of climate change, the observed declining ground water recharge potential and the unpredictable precipitation patterns in Germany, filling up of the open cast mines with water may not be the most optimal proposition when thinking for a sustainable future. The paper therefore seeks to highlight the limitation and challenges of the IBA/IBTA as a tool for regenerating mining regions and suggest measures and frameworks to address them. Keywords: IBA, IBTA, Mining Regions, Lausitz and Rheinishce Revier
