(Print) Will the Guidebook "Green and Blue Spatial Planning" be a Value Help for Styrian Cities to Become a "Smart City"
1 ABSTRACT The department of spatial planning in the provincial government of Styria in Austria was participating from 2008 till 2011 in the INTERREG IVC project GRaBS. GRaBS stands for Green and Blue Space Adaptation for Urban Areas and Eco Towns. The main ideas of the project were the exchange of experiences among the 14 partners from 8 european countries and to produce an adaptation action plan concerning climate change. Due to scientific researches there are existing a lot of evidences that
... t of evidences that the climate is changing. The atmospheric carbon dioxide concentrations are at their highest level for 3 million years and temperatures are increasing. Climate change is no longer simply something that will need to be addressed in the future, it is happening now and we will have to draw up climate change adaptation policies and strategies and implement them. Regional planning systems and urban spatial planning can help to reduce the vulnerability to the risks of flooding and heat island effects in cities. Green infrastructures including public and private parks, productive landscapes, green corridors and nets, green roofs and facades and also blue infrastructure such as water bodies, rivers, streams, sustainable drainage systems a.s.o. can mitigate the impacts of climate change. As a result of the GRaBS project and its outcome the Styrian Adaptation Action Plan, the department of spatial planning in Styria produced together with with an external office a guidebook of "Green and Blue spatial planning". This guidebook was introduced to the planners and the biggest cities in Styria in December 2012. 2 CONTENT AND AIMS OF THE GUIDEBOOK 2.1 Aims and tasksetting for the guidebook The tasksetting for the guidebook was to show up that integrating green and blue infrastructure in the spatial planning instruments, can be easily done by the municipalities. Spatial planning is a good mean to deal with the risks of climate change in a strategic way. Usefull measures for adaptation can be done on the level of planning for towns and municipalities. The main aim according to climate change is to increase the resilience of the citystructure and the use of the area. The aims of spatial planning with regard to spatial planning are: • Maintainance of microclimatic functions, temperature balance • Protection of the use of the area against natural hazards • Protection of groundwater, quality of streams a.s.o. • Protection of soil and soilquality These aims are the results of the given risks caused by climate change: hot islandeffects, aridity, heatstress, landslide, avalanches, forestfire, floddingdamages, the descent of groundwaterlevel, loss of soil through erosion a.s.o. The matrix in table 1 shows up how green and blue infrastructure can be used to reach the aims, mentioned before: 2.2 Content The guidebook itself delivers at the beginning a survey of the legal bases in the Styrian spatial planning and other law matters. In the Styrian spatial planning law from 2010 for example it is determined that the municipalities have to plan according to climate protection aims. Further on the guidebook describes the 3 spatial planning instruments, the local development concept, the landuse map and the masterplan. In the decription you will find the law background and the different paragraphes to find a sort of legal base for implementing the blue and green infrastructure and further on there are given advices how to integrate green and blue infrastructure in these instruments. The guidebook is not delivering all the possible measures in spatial planning but it shows up the possiblilities which are already existing in the spatial planning law. It might be a basis for the strategy of risk avoidance and could be the basis for the future planning.
