International sustainability objectives for land use, designated in the Sustainable Development Goals (SDGs) and Habitat III are formulated in general ways. The objectives need specification and regionalisation to raise impact. How far the general spirit of the objectives is reflected in regional and local practiceswill be discussed using the example of the annual scientific meeting of the German Academy of Spatial Research and Planning (ARL). This article shows that discussions about implementation comprise a richness of ideas in good practice and concepts for inner city development in some locations, whereas other disputes, for example, urban-rural interconnections, are missing.
