Yayın Quaternary uplift of the northern margin of the Central Anatolian Plateau: New OSL dates of fluvial and delta-terrace deposits of the Kizilirmak River, Black Sea coast, Turkey(Pergamon-Elsevier Science Ltd, 2018-12-01) Berndt, Christopher; Yıldırım, Cengiz; Çiner, Tahsin Attila; Strecker, Manfred R.; Ertunç, Gülgün; Sarıkaya, Mehmet Akif; Özcan, Orkan; Öztürk, Tuğba; Güneç Kıyak, NafiyeWe analysed the interplay between coastal uplift, sea level change in the Black Sea, and incision of the Kizilirmak River in northern Turkey. These processes have created multiple co-genetic fluvial and marine terrace sequences that serve as excellent strain markers to assess the ongoing evolution of the Pontide orogenic wedge and the growth of the northern margin of the Central Anatolian Plateau. We used high-resolution topographic data, OSL ages, and published information on past sea levels to analyse the spatiotemporal evolution of these terraces; we derived a regional uplift model for the northward advancing orogenic wedge that supports the notion of laterally variable uplift rates along the flanks of the Pontides. The best-fit uplift model defines a constant long-term uplift rate of 0.28 +/- 0.07 m/ka for the last 545 ka. This model explains the evolution of the terrace sequence in light of active tectonic processes and superposed cycles of climate-controlled sea-level change. Our new data reveal regional uplift characteristics that are comparable to the inner sectors of the Central Pontides; accordingly, the rate of uplift diminishes with increasing distance from the main strand of the restraining bend of the North Anatolian Fault Zone (NAFZ). This spatial relationship between the regional impact of the restraining bend of the NAFZ and uplift of the Pontide wedge thus suggests a strong link between the activity of the NAFZ, deformation and uplift in the Pontide orogenic wedge, and the sustained lateral growth of the Central Anatolian Plateau flank.Yayın Spatial transformation of traditional Ayvalık house: a comparative analysis of two houses(Istanbul Aydın University, 2023-11) Özker, Serpil; Tuğlu Karslı, UmutThe characteristics of traditional houses vary according to culture and geography and reflect cultural and historical identity of the society it belongs. Ayvalık is one of the historical settlements that preserves its original identity, due to its 19th-century traditional housing texture. The traditional houses of Ayvalık have a different ethnic structure shaped by Greek and Turkish identity. This ethnic structure reveals the traditional house texture with its characteristics embodying the influence of different lifestyles. Environmental factors emerging depending on the conditions and requirements of the period cause the damage of many traditional buildings. The research covers a comparative spatial analysis of two traditional Ayvalık houses located in İsmet Paşa Neighbourhood of Ayvalık and aims to read the transformation through the analysis of these two houses, according to the spatial characteristics of the traditional Ayvalık house defined by literature review. The reasons for selection of these two houses are: “first house has not been restored and has no a housing project, while the other house has been restored and has a housing project, and the buildings are adjacent and easily accessible by researchers”. Although there are a few traditional buildings in Ayvalık, it is very difficult to find all these features in one building. The number of sources analyzing the architecture of traditional Ayvalık houses is very limited, inventory studies of residential buildings are almost non-existent. Although the house number 2 is located in the historical site, the fact that its project has not been created is one of the important factors in case selection. By determining the spatial characteristics of the traditional Ayvalık house, the research also aims to contribute to the cultural assets documentation system and the related literature. In this context, the spatial characteristics of the traditional Ayvalık house are determined in line with the relevant literature, comparative spatial analyses of two houses are made in line with these characteristics, and the transformation of the buildings are examined through photographic documentation and on-site observation. As a result, it is determined that traditional Ayvalık houses have undergone changes in line with the needs of their users without losing their residential identity, which is generally their primary purpose of use from past to present and in the case of two houses which have the architectural characteristics of the traditional Ayvalık house; it is determined that the houses partially preserved their original spatial characteristics and preserved the traditional house texture with individual interventions and efforts.Yayın Istanbul’s community mobility changes during the COVID-19 pandemic: a spatial analysis(Istanbul University Press, 2023-08-15) Arık, Ahmet Okan; Çavdaroğlu, Gülsüm ÇiğdemCOVID-19 was the most recent pandemic to strike humanity. Moreover, this pandemic occurred during the most active period of global interaction and mobility, unlike pandemics like cholera, plague, and flu in earlier centuries. Many countries restricted domestic mobility after suspending international mobility to prevent the pandemic from spreading. Although these policies differ from nation to nation, they have affected the mobility of communities. This study examined spatial and non-spatial independent variables that affected how the community’s mobility patterns changed in various locations, including parks, transit stations, workplaces, grocery and pharmacies, and residential areas in Istanbul, Türkiye. The impact of the independent spatial variables on the mobility changes was examined after identifying the non-spatial independent variables influencing the mobility changes in 6 different areas. It was determined that the altitude variable, expected to impact how mobility changed, had no overall impact on the dependent variable. On the other hand, the dependent variables representing the mobility changes were affected by the independent variables representing the county center’s latitude and longitude values and whether the county is located near the sea. Regression analysis across Türkiye will be performed in upcoming studies using an updated version of the methodology used in this study.Yayın A geospatial analysis of the parks, emergency assembly areas, and urban green spaces in Izmir districts(IKSAD Publications, 2024-12-30) Çavdaroğlu, Gülsüm Çiğdem; Günay, NazanEnsuring equity in the allocation of public resources is a central objective for planners. In the context of planning, equitable distribution involves strategically placing resources or facilities to maximize accessibility for a diverse range of spatially distinct social groups. Equity in resource distribution has been a focal point of interest across numerous disciplines. The equity mapping method, which utilizes visualization techniques within geographic information systems (GIS), serves as a valuable tool for analyzing the spatial equity in the distribution of public resources. In this study, equity mapping was applied to parks, green spaces, and emergency assembly areas - resources of significant societal importance - to evaluate individual accessibility to these public facilities. The fundamental methodological approach to equity mapping involves overlaying the distribution of accessibility measures with socioeconomic data to analyze spatial variations in equity. This approach relies on spatial univariate, bivariate, or multivariate analysis, which examines the mapped data distributions and spatial patterns to identify and characterize spatial associations. The study answers eight research questions: (1) the number of emergency assembly areas per capita by district, (2) the number of children's playgrounds per capita among the population aged 0-19 by district, (3) the number of fitness areas per capita among the population aged 20 and above by district, (4) the amount of urban green space per capita among the entire population by district, (5) the distance of the nearest emergency assembly area to the district center, (6) the distance of the nearest emergency assembly area to the neighborhood center, (7) the number of parks within reach of the neighborhood center, (8) number of parks within 1 km of buildings on a district basis. Obtained fundamental patterns of inequity in the distribution of focused public resources in the study may help the municipalities better understand the current situation, make plans for the following years and ensure a more equitable distribution of public resources.Yayın Spatial distribution of Türkiye’s livestock products economy (1995–2020): sustainability-oriented visualization analysis(Liberty Publishing House, 2025-10-25) Aydın, Şahin; Özkan, Oktay; Azgın, Şükrü TanerIntroduction and Purpose: Livestock production plays a strategic role in Türkiye’s agricultural economy and is directly linked to food security and sustainable development goals. The aim of this study is to examine the spatial distribution of the livestock products economy in Türkiye between 1995 and 2020, visualize regional differences, and reveal long-term trends. Materials and Methods: The study utilizes province-level annual livestock product values (in thousand TL) obtained from official statistical sources. The data were analyzed through spatial methods, including choropleth maps, trend analysis, and growth rate evaluations for selected crisis years (2001, 2008, 2018, 2020). The analyses were conducted from a sustainability perspective, and regional production centers were identified. Findings: The results show that the Marmara, Aegean, and Central Anatolia regions lead in livestock product values, while the Eastern and Southeastern Anatolia regions have recorded significant increases in recent years. Trend analysis indicates that Konya, İzmir, Erzurum, and Diyarbakır achieved the largest growth, whereas smaller provinces exhibited relatively limited increases. In terms of crisis years, the sector continued to grow except during the 2008 global financial crisis, with a notable increase observed during the 2020 pandemic. Discussion and Conclusion: Overall, Türkiye’s livestock products economy demonstrated a steady increase between 1995 and 2020. The findings suggest that while the sector is sensitive to global shocks, it remains relatively resilient to domestic crises and pandemic conditions. Spatial analyses highlight the necessity of considering regional disparities in the development of sustainable policies.Yayın Exploring two decades of change in Turkish apiculture through spatiotemporal data analysis(Siirt Üniversitesi Ziraat Fakültesi, 2025) Aydın, ŞahinThis study examines the apiculture sector in Türkiye between 2004 and 2024 using data from the Turkish Statistical Institute, focusing on temporal, spatial, and relational dimensions. Time-series analyses, spatial visualizations, productivity comparisons, and correlation assessments were applied to reveal the structural transformation of the sector. The findings indicate a steady increase in modern hive numbers alongside a gradual decline in traditional hives. While overall honey production has grown, per-hive productivity has not improved significantly, suggesting that modernization alone is insufficient. Spatial analyses revealed that provinces such as Ordu, Muğla, and Adana remain dominant in production, yet substantial regional inequalities persist. Comparative and relational analyses highlighted a strong positive relationship between modern hive adoption and honey output, whereas traditional hives contributed little. The study concludes that Turkish apiculture is undergoing a modernization-driven transformation of hive structures and production practices, but efficiency stagnation and regional disparities necessitate complementary policies and practices to ensure sustainable development.
