Gothenburg is the second-largest city in Sweden, capital of Västra Götaland County Region. It is situated on the west coast of Sweden with the port area located along the Göta Älv River. Due to economic restructuring, waterfront redevelopment emerges as an attractive option to boost economic growth of the city. The aim of this paper is to shed light on conditions of the transformation process of two neighboring areas: Frihamnen and Ringön. Publicly initiated and privately executed waterfront redevelopment in Gothenburg transforms industrial grounds into residential and service oriented areas in Eriksberg, Lindholmen and Frihamnen. The collaborative process of a “developer dialogue” crafts a redevelopment in a consistent way with taking into consideration city’s long-term planning strategy, specifi c needs and opportunities of the neighbourhoods, but also market and fi nancial realities of development community. Another example is a slow and spontaneous transformation of post-industrial areas in Ringön, where still active small industrial fi rms, services, cultural and artistic initiatives take place in the close proximity to the city centre. Results show the waterfront transformation attracts “developers’ dialogue” giving the opportunity to build a coherence for spatial, environmental and socio-economic development. Yet fragmented redevelopment of brownfi eld areas strengthen polarization between dynamic and carefully planned Frihamnen and spontaneously growing Ringön. This paper contributes to the knowledge on the complexity of urban post-industrial transformation.
Kadıköy is a central district of Istanbul and a public transportation hub located on the shores of the Marmara Sea. It has been highly affected by recent developments in Istanbul. The triggers of change in Kadıköy are both planned (developments in transportation facilities and redevelopment of old buildings) and unplanned (i.e. proliferating cafes, bars, and cultural facilities). It is also affected by metropolitan scale dynamics (changes in Beyoğlu, the culture and entertainment center of Istanbul). These changes in Kadıköy have inevitable eff ects on the inhabitants and users. This article discusses the positive and negative aspects of both planned and unplanned development on public life and spaces in Kadıköy. Vitality of public spaces seems increased. The main changes are increasing population and building densities, changes in public space usage, and a proliferation of cultural facilities led by recently opened theatre halls.
As a result of changes taking place in urban water front structures and updating views on the design and functioning of public space that took place in the post-industrial era, maritime yacht ports began to appear in the most attractive regions of coastal cities. Their center-forming potential is more and more often noticed and used in the processes of transformation of waterfront areas in port cities, in order to revive water fronts and also as a tool for creating a new identity of revitalized places and interesting urban spaces.
Mining the lower seams in a sequence of shallow, closely spaced coal seams causes serious air leakage in the upper goaf; this can easily aggravate spontaneous combustion in abandoned coal. Understanding the redevelopment of fractures and the changes in permeability is of great significance for controlling coal spontaneous combustion in the upper goaf. Based on actual conditions at the 22307 working face in the Bulianta coal mine, Particle Flow Code (PFC) and a corresponding physical experiment were used to study the redevelopment of fractures and changes in permeability during lower coal seam mining. The results show that after mining the lower coal seam, the upper and lower goafs become connected and form a new composite goaf. The permeability and the number of fractures in each area of the overlying strata show a pattern of „stability-rapid increase-stability“ as the lower coal seam is mined and the working face advances. Above the central area of goaf, the permeability has changed slightly, while in the open-cut and stop line areas are significant, which formed the main air leakage passage in the composite goaf.
