Economic, social and environmental impacts of urban energy systems: the case of izmir natural gas network

Zengin, Beyda Nur
Urban infrastructure systems are high-cost urban components that provide physical and socio-economic functioning in daily life and affect livability and modernization processes. Infrastructure systems, which directly affect the urbanization and are shaped by existing urban settlements, are investments of which efficiency is achieved in the long run and directly related to the planning process. Energy networks, being constituted of natural gas and electricity, are among urban infrastructure systems. Urban energy services need to be provided in an uninterrupted, efficient and standardized way. While energy contributes to economic growth, social justice should be considered, and its impact on the environment should be minimized. The investigation of the relationship between energy infrastructure and sustainability becomes important at this point, considering the social, economic and environmental impacts of energy, which play vital roles in the continuity of the urban dynamics.Inthis study, it is aimed to reveal the socio-spatial effects of the natural gas system, which is cleaner and more efficient compared to other fossil fuels, although not being a domestic and a renewable energy resource. Sustainability of natural gas has been discussed with regard to its economic, social and environmental impacts. (1) Its vieconomic advantages or disadvantages have been examined by calculating investment costs and the annual heating cost of natural gas. Then, these costs are compared to other fuel types. (2) In social terms, the tendency of the households being fuel poor is examined by using a 10% fuel poverty indicator that seek to the households who are spending more than 10% of their income to demonstrate whether energy is distributed equitably to residents in the city and whether household can afford this energy service. (3) Finally, how natural gas consumption affects the pollutant emissions is examined, particularly during the winter season. The variation of the temporal and spatial distributions of PM10emission was compared by using the Kriging method.


Reading Vulnerabilities through Urban Planning History: An Earthquake-Prone City, Adapazarı Case from Turkey
ORHAN, Ezgi (Middle East Technical University, Faculty of Architecture, 2016)
Agglomeration of urban population, inadequate institutional capacity, unplanned urbanization, dense built environment, and industrial concentration are considered as the main causes of urban vulnerabilities against encountered disturbances. Planning decisions which regulate these factors are expected to make contribution to safer urban and social contexts and resilience of cities. However, in developing countries such as Turkey where disaster management is not an integrated part of urban planning process, p...
A research on resilience of urban public spaces: the case of Güvenpark, Ankara
Tümer Ergün, Ece; Büyükcivelek, Ahmet Burak; Department of City Planning (2020-10-23)
Cities are constantly changing and developing within the framework of social, economic, technological and political contexts. Therefore, it is increasingly common to accept cities as dynamic and complex systems instead of predictable systems. The strong relationship between urban planning and resilience has found itself in many different areas in the literature, for example, flexible planning strategies have been proposed in the urban planning literature to combat chaotic processes and sudden changes. Altho...
The changing morphology of urban greenways, Ankara, 1923-1960
Burat, Sinan; Aktüre, Sevgi; Department of City and Regional Planning (2008)
Despite the abundance of descriptive studies on the urban development plans of Ankara, analytical studies on specific features of these plans, especially on implementation and modification processes are scarce. This study examines the green space structure brought in Jansen’s 1932 development plan of Ankara, the way it was implemented and the modifications that a component of this structure was subject to. The 1932 Jansen plan is a holistic and comprehensive plan that contained a conceptual green space stru...
Politics of urban transportation local, national and international dynamics case of Ankara and Eskişehir road corridor
Öncü Yıldız, Mevlüde Ayça; Babalık, Ela; Department of Urban Policy Planning and Local Governments (2015)
This study aims to identify the factors that influence the development of Ankara’s urban transport system and to assess the effects of influencing groups and actors (referred to as assemblages in this study) on urban and transportation development of Eskişehir Road Corridor in relation with economic development, political decisions, institutional and legal frameworks. The thesis adopts a multi-level analysis method for researching influencing developments and assemblage relationships shaping urban transport...
Urban form, public life and urbanity: A study on Sakarya Pedestrian Area in Ankara
Coşkuner, Utku; Bilsel, Fatma Cânâ; Department of Architecture (2021-9)
Decision-making processes related with the physical arrangements and the urban form affect the city's social structure at a certain extent. In return, social transformations most obviously take the stage on the public spaces of cities that are open-to-all spaces of urban culture and are the main reason why cities define spaces of freedom. Besides the direct relationship it establishes with the public spaces of the city, the public realm is an intangible concept shaped by how the urbanites develop their comm...
