This study focused on cases that led sustainable urban development through the construction and utilization of organic greenery systems linking green spaces of urban peripheries with metropolitan areas. To that end, Berlin - Brandenburg's regional parks in Germany and Milan's Raggi Verdi, a radial green axis project, in Italy were selected for analysis as case studies. As frameworks for this analysis, this study has established existing infrastructure accessibility and linkage, recycling and cooperative management. The results of the case study analysis are as follows: First, the specialized spatial strategy based on the individuality of the green space outside the city rather than a uniform landscape was used as the foundation of the sustainable development plan. Second, physical linkage from the center of the city to the periphery contributed to the sustainable development of the overall metropolis by improving the economic value of the surrounding area as well as ecological and environmental values. Third, the central management system was established to reduce the administrative inconvenience caused by multiple administrative districts in the green space of urban periphery. The implications of applying the above results to Seoul, Korea are as follows. First, it is necessary to establish a differentiation strategy by re-establishing the identity of a green landscape in the urban periphery, because the green spaces of Seoul's periphery are dispersed and mostly have a repetitious mountain landscape. Also, it is necessary to actively link peripheral mountains and urban green areas to create ecological value and economic value, and ultimately to help the sustainable development of the city. Finally, building an integrated management system is required to solve fragmented green space management departments in most of the urban periphery's green spaces. In conclusion, this study shows the significant possibility that the sustainable development of a metropolis can be derived from the utilization, linkage, and management of the green space in the urban peripheries, which is extraordinary compared to normal centralized urban development.

Urban space expansion is an important symbol of the urbanization process and has always been an important topic in urban studies. In addition, for sustainable city management, it is important to identify factors that can influence, such as the driving force and direction of urban space expansion, from the stage of establishing an urban development plan. To understand these factors, by observing the expansion process of a specific city, it is possible to sufficiently observe how the urban spatial dimension changes. Through a series of processes, the spatial growth characteristics of the city are analyzed, and the influence and results of important factors are analyzed. For this purpose, this paper examines the changes in the city's outer boundary and land use structure through monitoring data on urban areas of 14 cities in Hunan Province, China from 2000 to 2016. Temporal and spatial regularity according to the urban space expansion of these cities were analyzed, and a preliminary assessment was made on whether the urban space expansion is coordinated with the urban population growth. The assessment result showed: (1) The urban space of most cities has been extended rapidly in 2000-2015 however, the rate and the intensity of urban space expanding has been declining. (2) The construction of the industrial park is the core driving force of the urban space expanding, and the change of the urban space structure is manifested as enclave city expansion because that the industrial park is usually far away from the city center. (3) The population agglomeration is another driving force of the urban space expanding. At this time, the urban space expanding is like boundary extension. (4) Except Changsha city, all of the cities has a high urbanization-area-growth elastic coefficient. It means that most of the cities should enhance the land use degree.

Congestion is a growing concern of many global cities and the demands on Infrastructure services within a locale coupled by the rising expectations from the growing population places stress on these cities. This entails the ability to build a sustainable community that requires an understanding and recognition of Population growth, changing demographics and the ever changing urban development on both a macro and micro level. Infrastructure is an integral part of Australian economy, particularly the 'Infrastructure Assets Management' which highlights the importance towards the development of sustainable communities for Melbourne's future. Melbourne 2030 is a comprehensive representation of government's response to a wide-ranging population growth within Melbourne metropolitan and surrounding areas. Urban plan and specific Infrastructure Assets Planning needs not only to provide sufficient Infrastructure to a community, but it must also be efficient and innovative so that it produces an optimised management system. A system that incorporates engineering techniques that will be sustainable for decades to come by maintaining an acceptable level of services to its intended community in an effective manner, which also strengthens service delivery. The fundamental challenges for optimization of Infrastructure with the Melbourne urban plan is, the ability to manage and sustain maintenance of Infrastructure to provide the acceptable level of service required by the community in a most effective manner which also strengthens service delivery to contribute towards Melbourne 2030. This paper particularly investigates some of the fundamental issues within the Melbourne urban plan such as Infrastructure Asset Management, AusLink and the Australian Road Management Act 2004, which the Governments at all levels must deal with to provide an economically viable solution to the changing Infrastructure so it may suits the needs and services the strategies of a metropolis.

The aim of this study was to present the direction of sustainable urban regeneration through the study of planning characteristics of urban regeneration reflected upon 'SymbioCity' concepts. This study was carried out through theoretical review and case study. In the theoretical review, the theory of 'SymbioCity', one of Sweden's representative urban development models linked to the concept of sustainable development, was reviewed and the framework was derived based on this theory. The framework of this study was finally derived from 'energy', 'ecology and environment', and 'historical and cultural resources'. The case study was conducted by selecting three urban regeneration projects($V{\ddot{a}}strahamnen$ BO01, Royal seaport and HafenCity Hamburg) in Sweden and Germany. Based on the results of case analysis, the direction of sustainable urban regeneration is as follows. First, in terms of energy, we should pay attention to synergy between energy and waste and energy production. Second, in terms of ecology and environment, plans should be made to maximize the use of existing resources in order to conserve natural resources and reduce energy consumption and economic costs. Third, in terms of historical and cultural resources, it is necessary to consider ways to preserve and recycle existing buildings with historical and cultural values. Finally, for the successful application of the planning elements, it is necessary to find the most appropriate application method through steady R&D in the country or project unit.

The purpose of this study is to suggest a strategy of creating sustainable city's streets by extracting a elements related the task related with society, economic, and environment. The method of this study is as follows. First step, we extract main task for developing sustainable settlements through studying literature review. Second step, based on the task for sustainable settlements, we generate various elements for developing sustainable street environments. Third step, we carry out a survey targeting experts related to field of urban environment. Fourth step, we analyze their priority about developing elements and the difference between groups. Last step, through correlation analysis between three task and elements for developing sustainable streets, we discuss the specific application around developing elements. The result of this study is as follows. Firstly, from a social point of view, the task related to connecting of historical and cultural characteristic is the most important thing. In a environmental view, it illustrates that application of technologies based on IT is more important than use of sustainable land. In a economic paint of view, it presents that the elements of city security & disasters are important.

Rising urban flood patterns are a universal phenomenon and a significant challenge for city government and urban planners worldwide. Urban flood problems range from relatively localized incidents to substantial incidents, which lead to cities being flooded for a few hours to several days. Therefore, the effect may be widespread, such as the temporary displacement of individuals, disruption to civic facilities, water quality degradation and the possibility of epidemics. The problems raised by urban flooding are highly challengeable and compound by ongoing climate change, with adverse implications for changes in rainfall and gaps in intra-urban rainfall distribution. Unplanned construction and invasions of large houses along rivers and watercourses have interfered in natural rivers and watercourses. As a result, the runoff has risen in proportion to the urbanization of the urban floods. The location of the relief camp and the priority for evacuation were determined, and the safest route to avoid floods were established. This method can be used for emergency planning in future flood incidents, and it will help plan disaster preparedness for Panchayat. This study will promote the flood plain's potential use for disaster management and land use planning virtually.

The idea that city culture can be employed as a driver for urban development has become part of the new orthodoxy by which cities seek to enhance their competitive position. Such development reflect not only the rise to prominence of the cultural sphere in the city development, but also how the meaning of culture has been refined to include new uses in order to meet the main objectives of sustainable development. This study focuses on the procedure how the cultural infrastructure and historical context can be applied for urban regeneration strategy. Two successful cases (Bilbao, Spain and Yokohama, Japan) were selected for analysis of strategies as a whole, background, main characteristics of culture-led urban regeneration strategies and their effect for urban regeneration have been analyzed in detail. In conclusion, lessons for the future development were suggested in terms of resources, planning and linking strategies.

The purpose of this study is to propose a new development method for urban residential area, considering the urban site and development conditions rather than just meeting the development limit and regulations. Gwangju Metropolitan city is investigated as a case city and the new method verifies a decision process of pertinent development types and housing forms in urban blocks. The consequences of this study are summarized as follows. The process of a new development method consists of four steps; First, current conditions of the residential area of Gwangju are analysed in order to find out the site characteristics and housing development situations. And the theoretical research is made to set up the development goals and objectives, regarding current trends and future paradigms of residential development. Next, the suitable development sites are selected, and their site characteristics and relevant development types for the future are compared and matched with a close analysis. Finally some pertinent housing forms for each development site are suggested, which fit well in terms of urban context and are appropriate for building up sustainable city in the future.

The application of appropriate technologies in a developing country is an opportunity to introduce green technology which may lead people to imagine a better life. This point is at the intersection of appropriate technology and sustainable development. This research focuses on Hatphain village where there is no clean water, sewage system, or power lines. Two environmental technologies (an unpowered water purification system, Ongdalsaem and an eco-toilet system, BeeVi toilet) were introduced, based on the concepts of the environmental self- sustainable village and feces Standard Money (fSM). We found that the Ongdalsaem was effective in reducing the concentration of nitrogen and lead in the water in Hatphain. The BeeVi water-free toilet was installed, allowing urine and feces to be separated and used as compost. We strived to spread ideas of sustainability using new eco-circulation experiences and encouraging learning about environmental technology through practical and playing facilities that residents managed themselves.

Jung-gu in Daegu is an old downtown that has led the development of Daegu as a representative center and a commercial area with historicity and placeless. However, an urban center is losing its vitality due to the transfer of city halls and the development of new towns. The downtown area that is still important in a city should lead urban development continuously so that it needs to return its vitality by rehabilitating the weakling urban center. Accordingly this study makes the school which shows drop in the number of students and classes in the school buildings located in Jung-gu, Daegu. Consequently this study figures out a cause for the occurrence of unused school facilities and find a solution as the space for local residents by investigating the facilities of schools, the surroundings, the reality, and the present condition. This study is conducted to examine actual situations of a downtown area that has gone through development and history of Daegu as a center. To this end, it aims to seek for methods to activate the city by relating the practical use of unused school facilities.
