Abstract
Systematic changes in spatial structuring are eroding the habitual relationship between the place-based economy and low mobility. Sparsely settled areas with a new quality in the enlarged area of the Federal Republic of Germany and patterns of depopulation in the course of demographic change as well as an affinity to the urbanity of the knowledge economy are reinforcing unequal spatial development. This puts the traditional treatment of areas with low dynamics or sparse settlement massively into question and calls for a re-examination of expectations of justice.
A re-interpretation of “equivalent living conditions” must allow a treatment of more strongly differentiated conditions, which promises sustainable functioning spatial structures. The promise of appropriate working and living conditions for everyone where he is growing up must be substituted by his enablement to lead a life in keeping with the times, possibly elsewhere (equality of chances). For a participation in working life adapted activities must also promoted in areas with low dynamics or sparse settlement.
Instead of redistribution a self-responsible enablement is more strongly emphasised, but not as a relinquishment of common development and responsibility. Challenges and tasks (basic conditions!approaches) aim at an “infrastructure of enablement”, as far as feasible spatial roles, comprehensive communication, orientation (education) and co-operation are concerned.
The article advocates a reality-oriented and insofar future-oriented treatment of unequal living conditions instead of normative invocations. In view of a fundamentally more strongly segregating spatial structure, the tendentially uninhabited areas should remain less a taboo than be an incitement for new differentiation-, co-operation- or cohesion concepts, in order to meet also the fiction of “catching up in development” or factual “passive redevelopment”.

Abstract
Diffuse deposits of fertilizers and nutrients caused by agriculture constitute a main problem for the maintenance of surface water bodies. A reduction of these deposits cannot be achieved by means of technical solutions, but only through a change in agricultural practice in a river catchment area. To stimulate and support such a change in behaviour should be the aim of a regionally adapted river area management.
In order to minimize the costs that would be caused by the organization of such a river area management, a methodical approach is developed in this work which distributes the competences for political influence efficiently in a river catchment area. Efficiency means in this context that measures for the control of diffuse pollution can be implemented with a possibly low sum of transaction and production costs.
This methodical approach is applied in the catchment area of the river Ems. In this area homogeneous groups of neighbouring municipalities are created with the aid of a geographic information system in which measures for the control or the reduction of diffuse nutrient deposits could be carried out more efficiently than is possible within the counties in which the municipalities are presently united.

Abstract
Kurzfassung
Im Rahmen des demographischen Wandels wird neben einer Alterung der Gesellschaft und der Zunahme von Personen mit Migrationshintergrund derzeit eine Abnahme der Bevölkerungszahlen als ein bedeutender Trend diskutiert. Neben schrumpfenden Regionen, die derzeit die raumordnungspolitische Debatte bestimmen, gibt es aber auch heute noch strukturstarke Regionen, die sich durch ein Bevölkerungswachstum auszeichnen. Hierzu zählt auch die Region Bonn. Prognosen zeigen, dass ihr Bevölkerungswachstum auch zukünftig im Gegensatz zu zahlreichen anderen nordrhein-westfälischen Städten und Regionen anhalten wird.
In dem Beitrag werden die Ergebnisse einer Studie über Wanderungsströme und Wanderungsmotive in dieser wachsenden Region vorgestellt. Ein Ziel ist darzulegen, inwieweit sich gesellschaftliche Veränderungen im Rahmen des demographischen Wandels auf Wanderungsentscheidungen auswirken.
Die Ergebnisse zeigen, dass die Wanderungsentscheidungen der älteren Generation zunehmend durch einen vorausschauenden Blick auf das eigene Alter geprägt sind und die Alterung der Gesellschaft bereits jetzt Auswirkungen auf Wohnstandortentscheidungen und den Wohnungsmarkt hat. Weiterhin führen neue Haushaltsformen, die als Folge der Pluralisierung der Lebensstile entstehen, zu geänderten Wohnanforderungen. Ebenso spiegeln sich veränderte Mobilitätsansprüche in den Auswahlkriterien für den Wohnstandort wider. Schließlich wird bei der Eigentumsbildung auch der Aspekt reflektiert, in einer wachsenden Region zu leben.
