Article Citation - WoS: 1Citation - Scopus: 1The Multi-Level Policy Learning of Environmental Policy: Insights From Izmir(Routledge, 2019) Velibeyoğlu, Koray; Mengi, OnurA European Union (EU) membership perspective is important for Turkey's harmonization with EU standards, which could have positive outcomes especially in the area of smart environmental management. However, as recent political developments suggest, Turkey is losing hope of full EU membership, and is searching for alternatives, such as privileged partnership. Active contributions of city-level good practices are urgently needed. Policy learning is a part of this process, and an emergent result of ever-changing negotiations involving a multiplicity of actors at the multi-level perspective (MLP). The present study investigates the glocal environmental policy of Izmir, via a review of recent governmental environmentally sensitive local innovative practices. The findings reveal that innovative environments that increase learning-by-doing and learning-by-using will become critical for environmental policy learning in Izmir and perhaps beyond.Article Citation - WoS: 24Citation - Scopus: 25Prospects for Cellulosic Biofuel Production in the Northeastern United States: a Scenario Analysis(John Wiley and Sons Inc., 2016) Dilekli, Naci; Duchin, FayeSecure access to energy and food are two of the challenges facing the Northeast region of the United States. Traditional biofuel feedstocks, such as corn and oil seed, are able to satisfy energy requirements. However, they compete with food production for desirable land and water resources and, in any case, are not likely to exploit the region's current comparative advantages. This study investigates a potential solution to the energy security problem in the Northeast: biofuel from advanced feedstock in the form of net forest growth and woody wastes, of which the region has abundant endowments. The federal government has committed to requiring 79.5 billion liters (BL) of advanced biofuel production annually by 2022. We evaluate both the physical capacity for its production and its cost competitiveness using an input-output model of consumption, production, and trade in the 13-state region. The model minimizes resource use required to satisfy given consumer demand using alternative technological options and subject to resource constraints. We compile data from the technical literature quantifying state-level biofuel feedstock endowments and the technological requirements for cellulosic ethanol production. We find that exploiting the region's endowment of cellulosic feedstock requires either making the price of biofuels competitive with gasoline through subsidies or restricting imports of gasoline. Based on this initial investigation, we conclude that the region can produce significant amounts of advanced biofuel, up to 20.28 BL of cellulosic ethanol per year, which could displace nearly 12.5% of the gasoline that is now devoted to motorized transport in the region.Article Citation - WoS: 40Citation - Scopus: 44Geological and Hydrogeochemical Properties of Geothermal Systems in the Southeastern Region of Turkey(Elsevier Ltd., 2019) Baba, Alper; Şaroğlu, Fuat; Akkuş, I.; Özel, Nedret; Yeşilnacar, Mehmet İrfan; Nalbantçılar, Mahmut Tahir; Demir, Mustafa Muammer; Gökçen, Gülden; Arslan, Ş.; Dursun, N.; Uzelli, Taygun; Yazdani, HamidrezaThe Anatolia region is one of the most seismically active regions in the world. It has a considerably high level of geothermal energy potential thanks to its geological and tectonic settings. The Southeastern Anatolia Region (GAP) is located in the south of Bitlis-Zagros Suture Zone (BZSZ) which is in the Arabian foreland. During the neotectonic period, the folded structures have been developed under the influence of tectonic compression from the Upper Miocene in the GAP Region where it is closely related to active tectonics. These tectonic activities produce more geothermal resources. Few studies have been carried out in this region for geothermal energy. Limited portions of the geothermal resources have been used both for thermal tourism and greenhouses in the GAP region. The aim of this study is to determine geological, tectonic and hydrogeochemical properties of a geothermal system in the GAP Region. The result indicates that the surface temperatures of geothermal fluids are from 20 to 84.5 °C A large number of abandoned oil wells, whose temperature reaches 140 °C, are found in the region. Also, hydrogeochemical results show that deep circulated geothermal fluids are enriched with Na-Cl and shallow geothermal system fluids have Na−HCO 3 and Ca-SO 4 characters because of cold water mixing and water-rock interaction. Cold waters are generally of Ca-Mg−HCO 3 and Ca−HCO 3 type. Cation geothermometers were used for determining reservoir temperature of the geothermal resources in the region. The results show that the reservoir temperature of these geothermal resources ranges from 50 °C to 200 °C. The isotope data (oxygen-18, deuterium and tritium) suggests that geothermal fluid is formed by local recharge and deep circulation.Article Citation - WoS: 21Citation - Scopus: 26Urban Crisis: ‘limits To Governance of Alienation’(SAGE Publications Inc., 2017) Bayırbağ, Mustafa Kemal; Penpecioğlu, MehmetThis article aims to develop a comparative framework of analysis to study urban crises, arguing that there is a need to establish the analytical links between ‘everyday life and systemic trends and struggles’, and thus to tie together the insights produced by ‘particularistic accounts’. It examines urban crises as political phenomena and brings the Marxist notion of ‘alienation’ to the centre of attention. We argue that ‘alienation’ – as a universal mechanism facilitating capital accumulation process via dispossession, and as negative mental/emotional implications of dispossession, is useful to establish those analytical links. We identify two domains, urban economic structure and urban political system, where alienation is contained. Public authorities deploy various containment strategies in these domains to govern alienation, and urban crises occur when these strategies fail. The post-2008 wave of urban upheavals could be explained by the failure of roll-out neoliberal strategies, which constitute the basis of our comparative framework.Article Citation - WoS: 7Citation - Scopus: 7Energy Efficient Building Block Design: an Exergy Perspective(Elsevier Ltd., 2016) Mert, Yelda; Saygın, NicelThis study introduces the exergy analysis method into the field of urban planning, in order to find out the amount of energy that can be conserved in a building block when an energy efficient construction design is applied. This was done in four steps. First, energy efficient design parameters were derived from the literature and design alternatives were developed accordingly. Second, data was gathered from the case area for the exergy calculations. Third, exergy analysis of existing building blocks and proposed design alternatives were separately carried out. Finally, the amount of decrease in the exergy loss due to suggested energy efficient design was found out. The results show that the exergy efficiency of the existing building blocks is about 2%, while the proposed design alternatives will be around 10-11%. The overall exergy loads of the alternative plans were found as 166.3 W, 225.1 W, 142.5 W and 137.8 W respectively for winter and 105.4 W, 140.0 W, 89.9 W and 86.3 W respectively for summer, on a housing unit basis. As a result, the suitability and importance of the exergy analysis on the built environment was proven, by revealing actual and considerable energy conservation and sustainable use of energy through application of energy efficient design parameters.Other Corrigendum: Alienated and Politicized? Young Planners’ Confrontation With Entrepreneurial and Authoritarian State Intervention in Urban Development in Turkey(Routledge, 2016) Penpecioglu, Mehmet; Taşan Kok, TunaArticle Citation - WoS: 18Citation - Scopus: 18Alienated and Politicized? Young Planners’ Confrontation With Entrepreneurial and Authoritarian State Intervention in Urban Development in Turkey(Routledge, 2016) Penpecioğlu, Mehmet; Taşan Kok, TunaPlanning in Turkey is dominated by powerful market interests and authoritarian state regulation, resulting in a conflictual socio-political environment. Caught in the crossfire between interventionist urban policies and a planning education system that is oriented towards the public good, planners have come to feel alienated from their work. This paper considers how young planners respond to these challenges, drawing upon questionnaires and semi-structured in-depth interviews with planners with fewer than 10 years of experience. Their confrontation with entrepreneurial and authoritarian state interventions in urban development alienates them from their ideals, leading them to explore new ways of dealing with increasing political authority and economic neoliberalism. The participants of the study came up with a number of diverse responses related to this process. Disappointed with the practice of their profession ‘lost planners' begin searching for alternative pathways outside their practice towards a more meaningful society. In contrast, ‘profiteer planners' focus on getting more business and play a conformist and opportunistic role in the existing planning practice; while ‘struggling planners' develop alternative ways to pursue the public good by participating in urban movements. In short, they cope with alienation through politicization, solidarity and the identification of new means of engaging with society.Article Citation - WoS: 23Citation - Scopus: 23Transportation Disadvantage Impedance Indexing: a Methodological Approach To Reduce Policy Shortcomings(Elsevier Ltd., 2015) Duvarcı, Yavuz; Yiğitcanlar, Tan; Mizokami, ShoshiAccess to transport systems and the connection to such systems provided to essential economic and social activities are critical to determine households' transportation disadvantage levels. In spite of the developments in better identifying transportation disadvantaged groups, the lack of effective policies resulted in the continuum of the issue as a significant problem. This paper undertakes a pilot case investigation as test bed for a new approach developed to reduce transportation policy shortcomings. The approach, 'disadvantage-impedance index', aims to ease transportation disadvantages by employing representative parameters to measure the differences between policy alternatives run in a simulation environment. Implemented in the Japanese town of Arao, the index uses trip-making behaviour and resident stated preference data. The results of the index reveal that even a slight improvement in accessibility and travel quality indicators makes a significant difference in easing disadvantages. The index, integrated into a four-step model, proves to be highly robust and useful in terms of quick diagnosis in capturing effective actions, and developing potentially efficient policies.Article Citation - WoS: 36Citation - Scopus: 40Conflicts Over Locally Unwanted Land Uses (lulus): Reasons and Solutions for Case Studies in Izmir (turkey)(Elsevier Ltd., 2016) Atay Kaya, İlgi; Kaya Erol, NursenLand use planning affects many different and usually conflicting interests. While every land use planning decision has a potential of creating conflicts, Locally Unwanted Land Uses (LULUs) are the most conflict facing subjects in urban land use planning processes. This paper aims to answer the question “what are the reasons and solutions for conflicts in the planning processes of LULUs”. This paper is based on a research examining LULU cases in İzmir, Turkey including solid waste facilities, fisheries and quarries to find out the reasons and the solutions for LULU conflicts. The research findings suggest that the conflicts stem not only from negative effects of LULUs on environment and community but also from procedural deficiencies such as lack of knowledge and lack of trust. The findings also call for planning processes with more consideration of local level and public participation seeking for consensus. Meanwhile, the conclusions underline the limitations for the success of participatory processes in which conflicts are resolved with attempts including symbolic benefits rather than considering exact interests of local people. © 2016 Elsevier LtdArticle Citation - WoS: 13Citation - Scopus: 12The Role of Government Policies and Strategies Behind the Shrinking Urban Core in an Expanding City Region: The Case of Izmir(Taylor and Francis Ltd., 2014) Özatagan, Güldem; Eraydın, AydaOver the last few decades, the term urban shrinkage has come to be accepted as a valid concept in international academic circles, and has gradually gained importance, with its causes the subject of well-documented discussion. While previous discussions of urban shrinkage have directed attention to cities shrinking as a whole, recent research started to recognize the case of shrinkage in growing cities and regions. As such, recent discussions of urban shrinkage indicate that patterns of shrinkage vary considerably from city to city, and from sub-region to sub-region, with the importance of local dynamics in responding to changing economic pressures given much consideration. Recent studies have tended to disregard the role of government policies and strategies put in place to facilitate the adaptation of the urban economies to the new conditions. Taking Izmir as an example, being a fast-growing metropolitan region in Turkey, this paper presents evidence of government policies and strategies aimed at enhancing the development of peripheral areas that have led to shrinkage of the metropolitan core. This paper focuses on this experience and discusses its implications.
