With the 2017 reform, Wien-Umgebung was divided into four parts, each of which was absorbed into a different predominantly rural county (Bruck an der Leitha, Komeuburg, St. Polten Land and Tulin). This stated objective is visible in most of the regional strategic documents currently in place: the Oslo-Akershus Joint Regional Plan for Transport and Land Use, the Vision of Vastra Gotaland and the Regional Development Programme (RUP) of Vastra Gotaland “VG2020”, Skane’s regional development strategy “The Open Skane 2030” and “Strategies for Polycentric Skane” (Table 2.5). In the case of Oslo-Akershus, the national government’s push for a joint regional plan on transport and land use stimulated co-ordination between both counties and municipalities (Box 2.4). In the case of the two Swedish sub-regions, the focus on polycentric development may also reflect the fact that the current perimeter of Vastra Gotaland and Skane is the result of county amalgamations in 1998-99.2 The Committee for Sustainable Development in Vastra Gotaland ensures effective co-ordination and mutual reinforcement between regional and municipal initiatives (Box 2.5).
