Confronting Complexities
The Development for Educational Purposes and Infrastructures in the Fringe Area of Yogyakarta, Indonesia
Paper Presentation in a Themed Session Maximilian Wanabakti
Government's consideration of the economic-equality result in new infrastructures outside the city. Paingan becomes favorable for educational purposes as a new economic center development. Unfortunately, there are no detailed policies and land-use plans for compact development. Each of education buildings is built spread across the area which contributes as a nucleus of urban growth. These infrastructures become a major catalyst of urban sprawl. This situation needs to be understood to deter sprawl development. In this study, high dependence on cars makes further developments influenced by road hierarchy. Nevertheless, the universities create a diverse population and agriculture’s plot size sells for new development making the urban structure in Kampong and the settlement rigid. This encourages more of the new or reconstruction in high-density and mix-use development which are the characters of a compact development. This paper discusses how the development of the education building in the fringe area contributes to a sprawl development. By unstructured visual observation, the justification for exploring urban evolution based on a comparison of limited satellite-image, urban forms, and architectural settings. This paper finds that the education buildings and road hierarchy are contributing to economic development, urban structure and sprawl to compact forms. The Infrastructures can shape sprawl to a compact development by limiting the economic attractiveness and the expansion of road network access to the education buildings while improving the accessibility and connectivity.
A Socio-material Framework for Urban Metabolism: The Case Urban Energy Flows of Saint-Nazaire, France and Its Hinterland
Paper Presentation in a Themed Session Bahers Jean Baptiste, Audrey Tanguy
Urban metabolism (UM) questions cities’ material and energy systems by identifying paths and transformation processes of all kinds of flows in urban contexts. In particular, one of its objectives is tracing the origin and destination of materials, energy, water, emissions, and waste flows to understand relationships between the cities and other spatial areas (hinterlands) that lead to political, social, and environment consequences. We propose a new approach which combines methodologies to understand the politics of UM and to analyze metabolic links between hinterland and consumption territories, in order to develop a "political-industrial ecology" of energy metabolism (Breetz, 2017; Cousins and Newell, 2015). To illustrate this approach, we developed a a case study of the energy metabolism of the Saint-Nazaire metropolitan area, located on the west coast of France. Saint-Nazaire is a predominant port zone in France, consisting in a complex network of highly energy-intensive industrial sites operating in the steel, petrochemical, and agri-food industries. In particular, the territory is home to the second largest crude oil refinery in France. The objective of this research is twofold. First, it aims to follow energy flows in order to provide insights on their territorial organization. Second, the resulting contextualized metabolism is used to discuss the potential contribution of a socio-material framework to evaluate energy transition initiatives currently investigated in the territory. The role and influence of different actors on metabolic flows and their management are a key issue to understand the governance of flows.
Prediction of Urban Expansion with the Aim of Preventing Ecosystem Damage: Using the Slope, Land Use, Exclusion Area, Urban, Transportation, and Hillside Model and the Environmental Conservation Value Assessment Map
Paper Presentation in a Themed Session Jinhoo Hwang, Raeik Jang, Seongwoo Jeon
The majority of the world's population lives in urban areas, and urban areas are increasingly expanding. This has damaged many areas that need to be conserved. In addition, the expansion of urban areas creates housing, transportation, environmental, and climate problems, and drives a policy need for urban expansion. In this study, urban expansion models were used to create policies to cope with urban expansion. The urban expansion model used in this study is the Slope, Land Use, Exclusion Area, Urban, Transportation, and Hillside (SLEUTH) model and has the advantage of being able to consider policy factors over other models. In this study, we examined the impact of the class of the Environmental Conservation Value Assessment Map on urban expansion by reflecting it in model operation. The SLEUTH model is an urban expansion model based on Cellular Automata, which can predict land-use changes as well as urban expansion. In this study, Yongin City, Gyeonggi-do was chosen as the focus of the study, an area where damage from the land use perspective caused by the expansion of urban areas. The land use status of the interim year was estimated using land cover maps and input data for model operation.
