Abstract
This paper analyses the spatial dimension of a socio-technical change (biogas) in agriculture through the lense of the concepts and results of studies about the legacy of the inner German border. It showsto what extent these spatial legacies could shape the agricultural transformation induced by the socio-technical change and describes several transformation paths. Simultaneously biogas contributes to the transmission of these legacies, especially considering the role of the large scale farms created during the postsocialist transition.
