Geoinformation in der kommunalen Abfallentsorgungs- und strategischen räumlichen Planung

Abstract

The declining growth and the resulting “perforation” of settlements cause high charges for infrastructure use and decreasing municipal tax revenue, which may be regarded as a “second rent”. Besides, property values decrease due to vacancy rate, the decay of rural settlements could be initiated. In order to both keep the costs for waste disposal constant as well as to develop a sustainable, compact settlement structure despite of shrinkage, synergies of overall and sectoral spatial planning should be improved. This paper points out a potential strategy to reduce expenses for the cost driver “collection of residual waste” as well as to use the waste disposal as a management tool of the settlement development. Throughout the entire process—from local migration analyses to vacancy rate and possibilities of inner urban development to waste disposal management—geo- and attribute-data were used, provided by different institutions. The data were managed, analysed and visualised by an open source geo-information and geo-database-software. Thus, the information of sectoral and overall spatial planning was overlaid and in result a sustainable, resource-efficient strategic planning is improved using a geo-information tool. Consequently, a centralisation of waste disposal could be improved by a GIS-assisted analysis of location and accessibility of central garbage containers. This centralisation is expected to allow a resource-efficient urban planning.
