Abstract

Japan has experienced population decline since 2010 and the situation is expected to become more severe after 2030 with forecasts indicating an expected 30% decline from 2005 to 2055. Many other developed countries such as Germany and Korea are also experiencing depopulation. These demographic changes are expected to affect society at many levels such as labour markets decline, increased tax burden to sustain pension systems, and economic stagnation. Little is known however about the impacts of population decline on man-made physical infrastructure, such as possible deterioration of current infrastructure or increased financial burden of sustaining it. Infrastructure can be classified into 3 categories: point-type (e.g. buildings), point-network type (e.g. water supply) and network type (e.g. road). The impact of depopulation may vary according to the type of infrastructure. Previous research in this area has been limited in scope (e.g. case studies conducted in a single city focusing on a single type of infrastructure) and method (e.g. most research in the topic has been qualitative). This thesis presents a new comprehensive study on the impacts of population decline on infrastructure in Japan, taking into account all types of infrastructure and using a quantitative approach. Data collection methods include interviews and two large scale questionnaire surveys, the first conducted with municipalities and the second, a stated preference survey, conducted with members of the public. The goal of sustainable development is relevant even in a depopulated society, and hence a sustainable development framework is applied to the analysis where social, economic, environmental and engineering impacts are investigated. The main findings indicate that some infrastructure impacts observed and reported in depopulated areas do not seem to be related to any population decline; moreover, the preferences of citizens for infrastructure development is very similar between depopulated areas and non-depopulated areas. The results also suggest that the premises of Barro’s overlapping generations model, very relevant to a discussion of intergenerational decision making and related sustainability, appear to be rejected in this context.

Abstract

Raumplaner*innen setzen sich mit Perspektiven auseinander, die Lebensqualität und zukünftige Entwicklung von Städten und Regionen betreffen und von gesellschaftlicher Relevanz sind. Basierend auf unterschiedlichen institutionellen und kulturellen Rahmenbedingungen sind Planungssysteme mit vergleichbaren Merkmalen entstanden. Diese Systeme sind an die jeweiligen kulturellen, normativen und räumlichen Voraussetzungen angepasst. In diesem Artikel präsentieren wir eine vergleichende Untersuchung, um Veränderungen in Planungskulturen aufzuzeigen im Kontext schrumpfender Städte in den USA, in Deutschland, und in Japan. Die Ergebnisse ermöglichen mit Blick auf Schrumpfungsprozesse Interdependenzen zwischen Veränderungen in Planungskulturen und gesellschaftlichen Veränderungen aufzuzeigen und Planungskulturen aus dem Blickwinkel der Refiguration von Räumen zu beleuchten. Schlussfolgernd stellen wir die Hypothese auf, dass Planungskulturen entsprechend einer polykontexturalen Logik durch eine Vielzahl von Faktoren bedingt werden, wie zum Beispiel geografische Einheiten (Staaten, Regionen, Städte) und auch Themen wie Stadtschrumpfung., Spatial planners deal with aspects related to the quality of life and future development of cities and regions, which are highly relevant for society. Due to various institutional and cultural settings, spatial planning systems emerged with comparable features. However, such systems have been adapted to specific cultural, normative, and spatial conditions. In our study, we conducted a comparison to investigate changes in planning cultures in the context of shrinking cities across the USA, Germany and Japan. The findings make it possible to detect interdependencies between changes in planning cultures and societal changes in the wake of shrinkage processes and potentially to place planning cultures in the perspective of a refiguration of spaces. We conclude with the hypothesis that planning cultures are framed by an array of factors in a somewhat polycontexturalized mode, such as geographic entities (nations, regions, cities), and also topics such as shrinking cities.
