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).
