Migration and the built environment: a spatial analysis of resettlement in Çeşme,Turkey

At the beginning of the twentieth century, the retreat of the Ottoman Empire caused a massive scale migration in the Aegean regions. This process was furthered by the Treaty of Lausanne (1923) between the Turkish Republic and Greece. Gradually, more than one million people were formally exchanged under the control of the respective national authorities. This study shows that the predictions made by political authorities regarding the expected adaptation and homogenization based on religious affiliations failed to materialize; instead, the process of migration generated its own unique and autonomous processes derived primarily from cultural aspects and social origins. This research examines the materialization of the migrants’ adaptation practices and the spatial transformations in the built environment at both urban and domestic level, in order to indentify spatial and related social conflicts that arose as a result of socio-cultural mixing through a case study of the Çe?me Peninsula, Turkey. The study concludes that the relationship between social space and the physical environment is intertwined, with spatial transformations based on residents’ home of origin, professions and economic prosperity positioned in a clearly defined hierarchy of meaning.     

Changes in Land-Use Preferences of Small-, Medium- and Large-Scale Industries Located in Metropolitan Areas (Case Study in Istanbul)

In metropolitan areas, the changing spatial land-use preferences of the industrial sector are the most important determinants in the forming of the macro-form. Metropolitan areas, especially in developing European and Asian countries, become troubled cities with agglomerations of population and investment as a result of failures to apply satisfactory macro-policies and plans throughout the country. Industrial investments on various scales and the land-use preferences of investors have changed over time. The land preferences of production and headquarters of the manufacturing sectors have become basic determinants in the formation of settlement systems due to the transformations that occur alongside technological, economic and social development. This article examines whether or not the basic land-use criterion of the manufacturing sector changes in small-, medium- and large-scale businesses according to their labour structure, defined through an examination of the sectoral structure and relations of scale. Taking the increasing rate of the Gross National Product of the industrial sector in metropolitan areas in every country into account, and examining the land-use preferences of various industrial sub-sectors and scales will serve as an important input when making new planning decisions. The industrial land-use criterion will be effective in the transformation, reorganization or directing of new focuses for the agglomerated industrial structure, especially in Istanbul, which features both Asian and European metropolitan area characteristics. This article will define the existing industrial structure of the Istanbul metropolitan area; and differences between the various scales of land-use preferences within industrial investments will be presented, based on the findings of two investigations carried out over a 5-year period. Several important criteria for industrial investors seeking to establish themselves in metropolitan areas will be determined in the article.     

Geochronology of plutonic rocks from the Sanandaj-Sirjan zone,Iran and new zircon and titanite U-Th-Pb ages for granitoids from the Marivan pluton

The Sanandaj-Sirjan zone of Iran is a metamorphic belt consisting of rocks which were metamorphosed under different pressure and temperature conditions and intruded by various plutons ranging in composition from gabbro to granite. The majority of these granitoids formed along the ancient active continental margin of the Neo-Tethyan ocean at the southeastern edge of the central Iranian microplate. Geochronological data published in recent years indicate periodic plutonism lasting from Carboniferous through Mesozoic to late-Paleogene times (from ca. 300 to ca. 35 Ma) with climax activity during the mid- and late-Jurassic. The age constraints for plutonic complexes, such as Siah-Kouh, Kolah-Ghazi, Golpayegan (Muteh), Azna, Aligoodarz, Astaneh, Borujerd, Malayer (Samen), Alvand, Almogholagh, Ghorveh, Saqqez, Marivan, Naqadeh and Urumieh, clearly indicate the periodic nature of magmatism. Therefore, the Sanandaj-Sirjan zone preserves the record of magmatic activity of a complete orogenic cycle related to (1) Permocarboniferous(?) rifting of Gondwana and opening of the Neo-Tethyan ocean, (2) subduction of the oceanic crust, (3) continental collision and (4) post-collision/post-orogenic activities. The formation of the Marivan granitoids, northwestern Sanandaj-Sirjan zone, for which we present U-Pb zircon and titanite ages of ca. 38 Ma, can be related to the collisional and post-collisional stages of this orogenic cycle.     

Growth estimations in settlement planning using a land use cellular automata model (LUCAM)

This article describes the main features of a Land Use Cellular Automata Model (LUCAM) developed within the scope a Ph.D. thesis by using both physical and socio‐economic data and on the basis of the relationships between the smallest cellular function and other functions that vary according to the fractal structure of settlements. An assessment of the research findings is also included. The article has five sections: Following the introduction, the evolution of land use models, in particular Cellular Automata (CA) based land use models, is described. Then, the main features of LUCAM are presented, and the basics of the criteria used in determining the model parameters is described. The model developed, which can easily be used in computer environments, aims to minimize the calculation time in growth estimation processes, and thus become a widely used tool. In this article, the model was applied to the settlement of Bursa (Turkey), and the results obtained were assessed. The conclusion section offers general guidelines on the use of the model and discusses the advantages of employing the model in CA based studies that are likely to emerge in the future.
