The aim of this research project is to systematically identify ways in which the objectives of regional cultural landscape development and those of preventive flood protection in river landscapes can be interlinked, taking into account the consequences of the climate change. In particular, recommendations will be developed for spatial planning with regard to its formal and informal instruments. For this purpose, exemplary projects will be empirically examined that merge the adaptation methods to floods and low water situations with processes in regional cultural landscape development. Contributions are provided by socio-scientific studies of institutions, which discuss the difficulties of integrating flood protection and regional cultural landscape development as problems of horizontal and vertical interaction, and spatial or temporal adaptability.
River management has been the subject of a number of important political reforms at a European and national level in recent years. Following the devastating floods in the summer of 2002, the German government drew up a 5-point plan for improving preventive flood protection. This initiative was institutionalised with the "Act to Improve Preventive Flood Control" in 2005. In addition, at the European level, the directive "on the assessment and management of flood risks" (Floods Directive 2007/60/EC) came into force in November 2007, and is now being implemented by the individual EU member states. The underlying concept for these measures is the concept of a river as an entity - from source to mouth, including tributaries and the landscapes of the river basin. This also addresses the level of the regional cultural landscapes and their composition.
The research is divided into the following work steps:
Literature study on climate change effects of floods and low water periods.
extreme periods of rain, heavy precipitation events and warmer summers with dry periods
today up to 2100
The climate effects examined include floods in residential, industrial and commercial areas, as well as of agricultural and forest lands. Conversely, however, extended dry periods with low precipitation lead to low water levels in river beds that have effects on their ecological, social and economic functions.
Objectives: To link preventive flood and low water protection with the development of cultural landscapes in the changing climate. The use of the "river landscape" as a strategic term offers the integrative potential to do justice to the spatial significance of river basins, to link the fields of activity "preventive flood protection" and "regional cultural landscape development", and to connect different spheres of activity, such as river catchment areas (as defined by hydrogeological criteria) and socially characterised cultural landscapes.
Regional cultural landscape development in river basins is an integrative and development-oriented approach - provided the precepts of the 3rd policy model for spatial planning in Germany ("Preserving resources, developing cultural landscapes") are followed. Regional cultural landscape development has the following potential:
Land use conflicts resulting from economic, ecological and social demands on river landscapes that may arise from measures for preventive flood protection and are likely to escalate in the course of the climate change.
