50 years after the groundbreaking International Horticultural Exhibition 1993 (IGA 93), which was also the Federal Horticultural Show, there could be another Federal Horticultural Show (BUGA) in the Stuttgart region - this time in association with the friendly neighboring cities of Stuttgart, Esslingen, Ludwigsburg and the Stuttgart Region Association (VRS).

The basis for the first step towards BUGA2043 is a feasibility study, which will be awarded as part of a two-stage pitch process. The aim of the process is to select an interdisciplinary team that impresses with initial conceptual approaches, technical expertise and the ability to further develop these approaches. The aim is to develop and evaluate conceptual perspectives for a sustainable transformation of the Neckar region between Esslingen, Stuttgart and Ludwigsburg - towards a productive river landscape that combines ecological, economic and social qualities.
