    Analyzing Landscape Change and Urban Sprawl in a Mediterranean Coastal Landscape: A Case Study from Izmir, Turkey
    (Coastal Education & Research Foundation, 2013) Hepcan, Serif; Hepcan, Cigdem Coskun; Kilicaslan, Cigdem; Ozkan, Mehmet Bulent; Kocan, Nurhan
    Hepcan, S.; Coskun Hepcan, C.; Kilicaslan, C.; Ozkan, M.B., and Kocan, N. 2013. Analyzing landscape change and urban sprawl in a Mediterranean coastal landscape: a case study from Izmir, Turkey Journal of Coastal Research, 29(2), 301 310. Coconut Creek (Florida), ISSN 0749-0208. The aim of this study was to analyze and interpret landscape change and urban sprawl in a coastal landscape of Turkey, in the province of Izmir, by remote sensing and Geographic Information Systems technologies with data spanning a 42-year period (1963-2005). Landscape change was analyzed from CORONA and ASTER images taken in 1963 and 2005, respectively. A postclassification algorithm for change detection was applied using ERDAS software. The results revealed significant changes in land cover and urban fabric during the period from 1963 to 2005. The built-up area increased from 8.18% to 28.88%, primarily at the expense of agricultural land. Agricultural land declined from 13.65% to 5.19% of the total area and was mostly isolated on the peripheries of the study area, which had a very patchy and scattered configuration. The urban fabric evolved on a linear path from a rural, low-density settlement character to an urban, high-density development. The compact urban form in 1963 transformed into urban sprawl by 2005, primarily along the area's transportation network and the coastline around Izmir Bay, Turkey. To minimize further urban sprawl and to maintain natural habitats, an ecologically sustainable growth strategy is required. For this purpose, landscape planning with special emphasis on developing spatially connected landscapes would be useful because the current urban master-planning process lacks a sustainable ecological vision.

    Establishing ecological networks for habitat conservation in the case of CeAYme-Urla Peninsula, Turkey
    (Springer, 2011) Hepcan, Cigdem Coskun; Ozkan, Mehmet Bulent
    The study involves the CeAYme-Urla Peninsula, where habitat fragmentation and loss, which threaten biological diversity, have become an urgent matter of concern in recent decades. The study area has been subjected to anthropogenic pressures and alterations due to ongoing and impending land uses. Therefore, ecological networks, as an appropriate way to deal with habitat fragmentation and loss and to improve ecological quality, were identified in the study area as one of the early attempts in the country to maintain its rich biodiversity. In this sense, core areas and ecological linkages as primary components of ecological networks were established on the basis of sustaining natural habitats. A GIS-based model was created to identify core areas and to facilitate the ecological connectivity. The modeling process for core areas and corridors combined 14 and 21 different variables, respectively. The variables were used as environmental inputs in the model, and all analyses were materialized in ArcGIS 9.2 using grid functions of image analysis and spatial analyst modules. As a result, six core areas and 36 corridor alternatives were materialized. Furthermore, some recommendations for the implementation and management of the proposed ecological networks were revealed and discussed.

    Post-occupancy Evaluation of a Built Environment: The Case of Konak Square (Izmir, Turkey)
    (Sage Publications Ltd, 2010) Malkoc, Emine; Ozkan, Mehmet Bulent
    Konak Square and its environs in the city of Izmir have a diversity of users and activities. The area was studied to establish how much such a public open space meets user expectations. Taking environmental factors into account and investigating user dissatisfaction will help in the design of similar public open spaces in the future. Some 271 public users and 56 specialists were consulted for their opinions through questionnaires. At the same time bioclimatic comfort conditions were calculated using the Olgyay method so that we could investigate the relationship between user satisfaction and these conditions. The central tendency (average) of general user satisfaction was calculated as 4.5 using the seven-step Likert attitude scale while the average for general satisfaction of specialist consultants was 4.1. Of the 271 questionnaires received 179 were completed on days when bioclimatic comfort conditions were not reached and, surprisingly, users indicated that they were more satisfied on these days. Konak Square was built in 2003 at a cost of (sic)3,600,000. The companies involved reported that bureaucracy and application costs were sometimes restricting factors during the design and construction stages.

    Visual Landscape Analysis of Urban Open Spaces: A Case Study of the Coastline of Gocek Settlement, Mugla, Turkiye
    (Sage Publications Ltd, 2010) Malkoc, Emine; Kilicaslan, Cigdem; Ozkan, Mehmet Bulent
    This article presents a visual analysis of the landscape characteristic of Gocek settlement, a Mediterranean coastal town affiliated to Mug. la, located in the southwest of Turkey. The aim was to provide an identity for a contemporary coastal town by studying use of its public open spaces. The analysis had four parts: data collection, development of forms, fieldwork and finally evaluation and synthesis. In the fieldwork section of the study, the coastline, which is considered outstanding in terms of its tourism potential, was divided into seven sub-areas and each was analysed in terms of spatial, perceptual, sensory and social aspects and the level to which it met user expectations. In addition to the visual analyses, a questionnaire was conducted with 70 respondents concerning their accessibility to the area, period of stay, what they did, reasons why they preferred the study area and the elements that enhanced or reduced the visual quality of the area. The results of the visual analyses and questionnaires carried out in the seven sub-areas, showed that overall people's perception of the public spaces were generally at a medium level on the scale used. So, within this context, the message was that the visual quality and liveability of Gocek, which aims to make progress in terms of tourism, have to be enhanced.
