The phenomenon of urban blight dates back to the 19th century when industrialisation starting in Europe and North America initiated an uncontrolled urban growth in combination with strong demand in cheap an quickly constructed housing. Ghettoisation of mainly the working-class population and other "marginal groups" were the consequence together with a constant decay of single buildings, whole blocks and quarters. These general aspects of urban blight with its additional facettes or aspects residential, commercial, industrial, physical, functional and social blight can be presupposed and will not be topic of this paper. Nevertheless urban blight is by no means a topic of the past, it still today challenges apart from geographers a remarkable number of other disciplines (urban and landscape planners and designers, economists, sociologists, medical sciences, etc., not to forget politicians, the media, and last but not least the city dwellers themselves). While urban blight, urban decay, - decline, or - crisis originally seemed to be a problem of the big cities and metropolises it meanwhile also affects the small towns and centers. By the example of two Styrian small towns, Murau and Eisenerz, both counting less than 5.000 inhabitants each some of the many reasons for their being confronted with symptoms of urban blight will be addressed together with the up to now largely unsolved question which possible counter strategies could be successfully applied. One namely "urban redesign" has been chosen from a number of others mainly because it has been selected by the city of Eisenerz as a strategy against urban blight and to fight the dramatic population losses of 7867 citizens between 1951 (pop.: 12948) and 2010 (pop.: 5087). The crucial questions for the future to be discussed facing the present world wide monetary crisis will be: 1. Will there be enough money to finance the necessary rescue measures? 2. Who pays and bears the risks of a failure? 3. Is it worth while and justified to invest huge amounts of public money into a seemingly bottomless barrel or 4. borrowing an idea from the human hospice-movement: would it not be wiser, more human, and cost-efficient to spend much less money for those measures only that are needed to guarantee a patient (city) with little or uncertain perspectives for the future a survival in dignity. Knowing that the hospice movement was severely questioned in its initial phase although today it is widely accepted and respected the transformation of this idea into the urban sphere as one means to discuss the problem of urban decay and urban blight seems justified.

Burglary and robbery rates in St. Louis, Missouri, are investigated as functions of census unemployment levels taken in 1970 and 1980 for twelve yearly cross sections of crime rates, with all rates aggregated to the level of census tracts for analyses. The relationship of burglary and robbery rates to unemployment is found to be positive, and the interactive (logged) model is found to be the one most consistent with theory as well as the best predictive model. The magnitude of unemployment effects is large, and the policy implication is that urban areas fighting crime would benefit substantially from successfully targeted employment programs.

Nachbarschaftsgärten und Interkulturelle Gärten, bepflanzte Baumscheiben und Fassaden mit Obst zum Selbsternten, temporäre Gemüsebeete auf Brachen und blühende Straßeninseln werden als Ausdruck einer neuen urbanen Agrikultur interpretiert. Nicht nur Streuobstwiesen und Äcker am Stadtrand, auch Selbsterntefelder und die Nutzung temporärer Wälder als Kurzumtriebsplantagen gehören neuerdings zu den als produktive Stadtlandschaften bezeichneten landwirtschaftlich und gärtnerisch genutzten stadtregionalen Grünräumen. Landwirtschaft und Gartenbau in der Stadt scheinen en vogue, und die Zahl neuer Projekte wächst kontinuierlich. Aber auch in den Fachdiskussionen befassen sich zahlreiche Beiträge zu innovativen Ansätzen für eine zukunftsfähige und nachhaltige Stadtentwicklung mit dem Phänomen des urbanen Gärtnerns und der urbanen Landwirtschaft. Dieser Band betrachtet auf der Grundlage aktueller Forschungsergebnisse und Praxisbeispiele die Relevanz des Themas für die Zukunftsfähigkeit der Städte und Stadtregionen. Identifiziert werden neue Herausforderungen für den kommunalen Umgang mit Landwirtschaft und Gärten.
