Expertenworkshop Flächennutzungsmonitoring - Bedarf, Anforderungen, Lösungen

22.01.2009, IÖR Dresden:

Although it differs greatly throughout the country, land take is still considerable in Germany. Sustainable development, which requires settlement development to be uncoupled from economic development, has therefore yet to be achieved. Current land audits are now based on aggregated figures (municipal basis) from official land statistics. Being purely quantitative assessments, these figures present land development only in cumulative terms, and are inadequate for describing the complexity of land take and its repercussions for the landscape, soils, recreation and protected areas, or for infrastructure costs. Spatially differentiated statistical monitoring of land is needed that enables political and spatial science to evaluate development reliably.The research questions that need to be addressed for the differentiated monitoring of settlement and open space development include: What indicators are particularly important for assessing development, and how can they be integrated into practical procedures and methods? How, at what spatial resolution and at what time intervals are these indicators to be determined? What data bases are suitable for calculating the indicators? How can the indicators be made available and clearly visualised on the basis of interactive Internet technologies? A number of completed and on-going research projects can contribute to answering these questions. In the past, a number of indicators have been developed and tested on smaller areas. In the recent past, a procedure for calculating various space-related indicators has been developed at the IOER, which, thanks to a high degree of automation, is suitable for application throughout the country. Since it draws only on geo-basis data that are regularly updated, it is also very well suited for far-reaching permanent monitoring.In this research area, a micro-scale GIS-aided audit system for assessing the sustainability of land-use development is thus to be planned, developed, and put into permanent operation. The aim is to provide the continuous, country-wide, cross-scale computation of important parameters of settlement and open space development for publication in the form of a comprehensive indicator system. This system is to include indicators for describing settlement density (incl. building density, site coverage, floor space density, and building volume density, to some extent down to the block level), settlement structure (incl. compactness), open space structure (share of different types of land use, disturbance potential in protected and recreation areas), and the transport infrastructure (unfragmented open spaces, traffic infrastructure audits, network densities, public transport endowment, etc.). After calculation of the core indicators, this indicator system is to be successively supplemented by further indicators For this purpose, findings from the research areas environmental quality (landscape structure and quality indicators), eco-efficiency (material and energy flow indicators), and environmental risks (vulnerability and risk indicators), will be taken up, examined as to their usefulness for integration into the monitor, and after comprehensive testing and process optimisation, calculated for the whole of the country.The work in this research area is conceived as a permanent task, for only continuous and highly precise computation of indicator system parameters using a uniform procedure permits relevant changes in land use to be identified that, even if small and creeping, accumulate over time. This alone will permit exact assessment and comparison of spatially very differentiated settlement and open space developments (from urban agglomerations to peripheral rural areas). The settlement and open space development monitor is intended for planners and decision makers at the various levels of spatial policy, from the federal government to local government, associations, and non-governmental organisations, scientific and educational institutions, and the general public. The indicators are important for a range of policy areas and for their integration, especially spatial planning, environment, agriculture, housing, and transport and traffic.
