Analysis of Land Use/Land Cover Changes and Prediction of Future Changes With Land Change Modeler: Case of Belek, Turkey
(Springer, 2023) Akdeniz, Halil Burak; Serdaroğlu Sağ, Neslihan; İnam, Şaban
In the areas declared to be a tourism center by state planning, a rapid tourism-related development occurs depending on the investments in tourism, which causes a dramatic land use/land cover (LULC) change. Determining, monitoring, and modeling of LULC changes are required in order to ensure the conservation-use balance and sustainability within such vulnerable areas that are under development pressure. This study consists of four steps. In the first step, the Landsat images dated 1985, 2000, 2010, and 2021 were classified using the maximum likelihood method and the LULC of Belek Tourism Center located in Turkey were determined. The second step included the identification of areal and spatial changes between the LULC classes for the four periods. In the third step, the LULC changes in Belek Tourism Center for 2040 were modeled using the land change modeler. Last step evaluated the relationship between the modeled spatial development pattern and the current planning decisions. According to the results obtained during 36 years, the rates of built-up, forest, and water body areas have increased by 11.91%, 13.67%, and 0.82%, respectively, whereas the rates of barren land and agricultural areas have reduced by 22.25% and 4.15%, respectively. The LULC map modeled for 2040 predicts the built-up areas to expand by 8.25% and the agricultural areas to shrink by 5.42% by comparison with 2021. This study will contribute as a key measure for planners, policy-, and decision-makers to make decisions related to sustainable land use in the areas declared to be a tourism center.

Assessment of the State and Impact of Tourism Activities in Kenya
(2021) Gündüz, Elif; Agayi, Collins
Tourism plays a significant role in the economic development of Kenya. However, the development of the sector continues to face challenges arising, both locally and globally. This study identifies and analyses these problems and how they impact tourism activities. The study provides a brief overview of the role of international tourism by highlighting its socio-economic, environmental, and political contributions to the country's development. Also discussed are the sustainability issues around mass tourism and its effect on the environmental, social, economic, and cultural aspects of life in the host regions. The key to addressing the tourism sector's performance is the understanding of the significant role the market plays. Focusing on this, the study examines emerging issues in the Kenyan tourism sector i.e. seasonality, overreliance on the international market, impacts of tourism infrastructure development on space, among others, and their roles in shaping the tourism industry. It is established that overdependence on the international market exposes Kenyan tourism to global risks that could result in the collapse of the sector, thus negatively affecting the economy. To safeguard the Country from external risks, the study proposes strengthening domestic tourism by encouraging local investors' participation in international tourism. The study also identifies the main problems related to tourism activities in Kenya including; pollution, destruction of cultural heritage, the threat to the health of both human and aquatic life, human-wildlife conflicts, less economic benefits to local communities and host nations dues to dominance by transnational corporations, social ills like drug abuse, luring of young girls into sex resulting into early pregnancy and school drop-out among other problems. The findings of this research are based on a review of previously done research literature, academic documents, government reports, among other secondary and primary sources of data.

Challenges To Urban Housing Policies Implementation Efforts: the Case of Nairobi, Kenya [article]
(2020) Agayi, Collins Ouma; Karakayacı, Özer
PurposeThe arrival of native African communities from rural Kenya looking for opportunities led to population growth. Nairobi, therefore, has rapidly urbanized and sprawled 18 km2, and 688 km2 in 1900, and 1963 respectively. With population growth, housing demand has surpassed supply resulting in the housing crisis. The aim of this paper is to a) examine the policy and legal efforts put forward to address the housing problem in Nairobi, b) discuss the challenges to the urban housing policies implementation efforts, and c) make suggestions based on the findings of social, economic and infrastructural impacts of the intervention measures. Design/Methodology/ApproachThe research establishes that government efforts to address the housing problem through measures like urban migration restriction, employer housing, housing schemes, slum demolitions, and slum upgrading have not been successful due to challenges of land security tenure, gaps in policy enforcement, and compliance, insufficient public participation among others. FindingsThe paper makes appropriate suggestions to reform the policy approaches by focusing not only on housing aspects but economic, and land tenure reforms, and the extent of public involvement.Research Limitations/Implications The study analyses secondary sources including research articles, theses, and governments whose data were collected through primary methods like interviews, field observation, and administration of questionnaires. It, therefore, limited the findings in case of Nairobi.Practical Implications The study contributes to recommend that provision of the basic services be carried out in the slums alongside and economic empowerment programs to relieve the residents of financial poverty. Slum upgrading programs should therefore seek to impact the socio-economic lives of the slum dwellers. Originality/Value This study explores past and present efforts by different regimes and non-governmental organizations to give an answer to the housing crisis in Kenya. and the subsequent development of slums and informal settlements.

Determination of Urban Sprawl Effects on Farmlands Value Using Gis
(2019) Karakayacı, Zuhal; Karakayacı, Özer
This paper presents to determine urban sprawl boundaries and the factors of affecting farmland value in urban sprawl. Urban sprawl index is calculated to identify its boundaries and Analytic Hierarchic Process Method is used for determined to weight for the factors. By using these weights in the Geographic Information System (GIS) technology, the value map is created. We illustrate that the farmlands in urban sprawls lost their properties and transformed into urban lands. The analyses revealed that farm criteria have no effect on the lands in urban sprawl. Both urban and rural solutions should be improved in order to prevent the abuse of fertile farmlands that occurred as a result of urban sprawl.

Determining a Strategy for Sustainable Development of Local Identity: Case of Birgi (i̇zmir/Turkey)
(2018) Topçu, Kadriye
Today, it is difficult to retain and strengthen local character in the globalizing world. Showing the advantages of small towns and to strengthen their identities with focusing on ‘small realities in a globalizing world’’ by increasing the value of local differences is an important subject in the global atmosphere. From this point, taking the advantage of Birgi’s (Izmir/Turkey) having strong natural, man-made and cultural identity, this study aims to find out the most appropriate planning strategy for the sustainability of Birgi’s (İzmir-Turkey) local character and identity which was selected as a case study. This study made some on-site observations for establishing the existing local identity potentials of Birgi. After these observations, within the scope of the study, first of all, strengths, weaknesses, opportunities and threats (SWOT factors) of the settlement were identified. Additionally, to determine the most appropriate planning strategy, a numerical SWOT analysis called A’WOT analysis which is the combination of Analytical Hierarchy Process (AHP) and SWOT analysis was used. Then, identified SWOT factors prioritized by an expert group (35 person) using A’WOT analysis. After finding general and local priority values of SWOT factors, four planning strategies were displayed by using TOWS matrix. Then, the most appropriate strategy among these planning strategies was chosen according to their priority values. In conclusion, it was found that “Entering to Slow City Movement” planning strategy is the most appropriate and important strategy between prioritized planning strategies for the sustainability of Birgi’s local identity.
Determining People's Design Priorities for Neighbourhood Units: a Study in Liverpool, Merseyside
(ICONARP, 2022) Levend, Sinan; Fischer, Thomas B.
Local planning authorities and developers aim at designing and regenerating neighbourhoods in which people want to live. However, this aim is difficult to achieve if participation is conducted poorly. As a result, people may live in places that are created according to the ideas of designers and the priorities of market conditions and not according to their own. Therefore, determining people's preferences is essential for livable and sustainable neighbourhood design. This paper introduces and tests a method for determining people's design preferences, namely an Analytic Hierarchy Process (AHP) methodology. The method is basedon making pairwise comparisons of key design principles and structural factors of neighbourhood units. The testing was conducted in Liverpool city centre. Here, it was established that participants' priorities in neighbourhood design are safety, affordable housing and accessibility, respectively. Also, participants prefer to live in non-gated detached and semi-detached housing communities. This article offers an empirical contribution to the participatory neighbourhood planning literatüre.

Geographic Information Systems (gis) Based Accessibility Modelling Approach in Micro Scale Considering Physically Disabled Users: Case Study of Mimar Muzaffer Campus, Selcuk University
(2018) Ertuğay, Kıvanç
The concept of physical accessibility refers to the availability, capability, comfort, convenience of transportation processes considering different urban obstacles / barriers and costs. In this context, there are many approaches for the measurement and evaluation of physical accessibility in the literature which are used extensively as a decision support especially in transportation, geography and city and regional planning related disciplines. Although there are large number of modelling approaches on physical accessibility modelling in macro scales (such as national, regional, city and town scales), the research on physical accessibility modelling, in micro scales (such as street, human, neighbourhood scales), which couldconsider all the details of the perceived space seem to be extremely limited. This study, which emerged from this lack of accessibility modelling literature, proposes a Geographical Information System (GIS) supported methodology to demonstrate how physical obstacles / barriers such as “buildings, landscape areas, walls, steps, stairs, pits, unfitted street furniture, other (garbage, rubbles, trees etc. that prevent access) etc.” and transitions such as “ramps with appropriate slope, elevators and/or “removing walls / steps” could be defined in GIS environment and how access and circulation in (outdoor) urban space could be modelled considering these physical obstacles / barriers and transitions especially taking physically disabled users (users using wheelchair, bicycle, baby's car, market car etc.) into consideration in the micro scale. The proposed accessibility modelling methodology is conducted at Selçuk University, Faculty of Architecture, Mimar Muzaffer Campus Area. A polyline-based spatial GIS database has been developed to demonstrate how physical barriers and transitions could be modelled in micro scale in GIS environment in order to evaluate physical accessibility. The results of the study could provide an accessibility based decision support environment by visualizing and presenting how physical obstacles in urban space prevent physically disabled users from access and circulation and how the elimination or removal of these physical obstacles and creation of transitions will create a difference in access and circulation for the users in a comparable manner especially in micro scale. This study is thought to make a significant contribution to increase accessibility levels of physically disabled users (users using wheelchair, bicycle, baby's car, market car etc.) in the outdoor urban areas in terms of demonstrating their accessibility and circulation capabilities. The primitive experimental model related with this research was carried out with the participants of the accessibility measurement and modelling session at the 3rd National Disability Workshop which is held in Selcuk University, Mimar Muzaffer Campus dated 2-3 May 2018.

The Glocalisation of Istanbul's Retail Property Market
(EMERALD GROUP PUBLISHING LTD, 2022) Eren, Fatih; Henneberry, John
Purpose The continuation of globalisation and liberalisation processes has prompted the restructuring of many national and local property markets. The research examines the evolution of Istanbul's retail property market to identify how global and local agents engage with one another to produce a unique glocalized outcome. Design/methodology/approach The morphogenetic approach is adapted and applied to analyse the dynamics of market change. The focus is on the character and behaviour of national and international market actors and how they interact with the wider political economy. The research uses a combination of elite interviews, document analysis and corporate case studies to obtain empirical evidence. Findings The liberalisation of the Turkish economy heralded the entry of the first international companies into Istanbul's retail property market in the 1990s. International involvement expanded rapidly after 2004, accelerating the process of market re-structuring. However, while the number of global buy-outs increased, the expansion of local property companies-and the establishment of some international/national corporate partnerships-was even more marked. This resulted in a glocalised market with a strong and distinctive local culture. Originality/value Istanbul has been a major centre of trade for millenia. This is the first substantive analysis of the recent restructuring of the city's retail property market. Previous research on market maturity and market evolution has paid limited attention to the dynamics of change. The paper describes the use of a process-based theoretical framework (morphogenesis) that was explicitly designed to analyse structural shifts in socio-economic conditions through an examination of the characteristics and behaviours of the actors involved.

İnşaat Odaklı Ekonomide Kentsel Dönüşüm Mevzuatının Dönüşümü, Pratiği ve Planlama İlke-esasları Çatışması: Mahkeme Kararlarında Ankara Örneği
(2021) Çamur, Kübra Cihangir; Korkmaz, Cansu
Kentsel dönüşüm ve yenileme süreçleri, plan-projelerin uygulama aşamaları mevzuatla düzenlenmektedir. Türkiye, kırılgan ve gelişmemiş siyasi-ekonomik yapısının bir sonucu olarak, ekonomik sorunların hızlı çözümüne yönelik bir politikayla “inşaata dayalı ekonomik büyümeyi ve kentsel dönüşüm stratejisini” benimsemiş; 2012 yılında kentsel yenilenmeyi dönüştürmek ve hızlandırmak için hazırlanan 6306 sayılı Kanun ile “afet riskli alanlar” dönüşüm kapsamına alınmıştır. “Afet riskiyle mücadele”nin odağa alınmasıyla toplumsal ve bireysel itiraz temelinde engellerin ortadan kaldırılması hedeflenmiş; bu alanların yanı sıra gecekondu alanları, henüz yapılaşmamış alanlar, hatta koruma alanları kentsel dönüşümün konusunu oluşturmuştur. Bu araştırmada, “dönüşüm alanlarının ve sınırlarının tespiti, ilan edilmesi ve uygulanmasına yönelik kentsel dönüşüm planlarının-projelerinin mahkeme süreçleriyle iptallerini içeren 2005–2012 dönemi Ankara örneğinde" incelenmiştir. Çalışmada planlama ilke ve esasları ile kentsel dönüşüm arasındaki çatışmanın nedenlerinin, ekonomik ve sosyal bileşenlerin planlama süreçlerine entegrasyonu koşullarının ve olanaklarının tartışılması amaçlanmıştır. Araştırmanın sonuçlarına göre iptallerin önde gelen nedenlerini, dönüşüm projelerinin üst ölçekli planlara ve hiyerarşiye aykırılığı; dönüşüm alanlarının ve sınırlarının kentsel dönüşüme uygunluk kriterleriyle örtüşmemesi; alan-sınır tespitinde gerekli teknik incelemelerin yapılmaması; önerilen yoğunlukların ve kullanım kararlarının planlama ilke-esaslarıyla ve kent bütünündeki planlama kararlarıyla uyuşmaması ve mülkiyet dağılımının hakkaniyet temelinden uzak olması oluşturmaktadır.

An Integrated Framework for Assessment of Urban Forms and Their Transformation
(Istanbul Teknik Universitesi, Faculty of Architecture, 2023) Arat, Muzaffer Ali; Topçu, Mehmet
This paper addresses an integrated framework on the basis of different urban morphological theories: histocico-geographical approach, space syntax, and the Morpho method. It includes eleven criteria focusing on the assessment of urban forms and their transformations. These criteria are the accessibility of streets, connectivity of streets, intelligibility, synergy, street block size, plot size, building coverage, floor area ratio, block-plan size based on the town-plan or ground plan; building height and total constructed area (density of buildings) based on building fabric. Sekiz Mahalle (Konya, Turkey) is used to validate the methodological procedures of this integrated framework. The implementation of the methodology enables a strong basis for how an urban area should be transformed, and what should be followed before any interventions in the urban landscape. It is argued that this methodology can provide a smoother transition of the physical form of cities. It can play a substantial role in the preparation of municipal plans and designs in which any change is needed, balancing the conservation and transformation of morphological constituents of the urban landscape.
Kentsel Dönüşüm Sürecine Yönelik Anahtar Bir Çerçeve ve Konya Deneyimi
(2020) Osmanlı, Nurullah; Karkın, Kübra; Serdaroğlu Sağ, Neslihan
Günümüze kadar kentsel bozulma sorunlarını çözmek için kentlere özgü birbirinden farklı kentsel dönüşüm süreçleri yaşanmıştır. Kamu sektörü tarafından uygulanan kentsel dönüşüm projeleri çoğunluğu oluştursa da kentsel dönüşüm çabalarının sürdürülebilirliğini sağlamak için toplum ve özel sektörün sürece dâhil edildiği ortaklık modelleri ile daha başarılı bir süreç yaşanabileceği kabul edilmektedir. Dünya örnekleri kentsel dönüşüm için kullanılan politika, düzenleyici araçlar, halk katılımı ve yönetim yapısı bakımından farklılık gösterse de ortak nokta olarak kentsel alanların yenilenmesi, yeniden canlandırılması, kültürel bağlamlarını devam ettiren kimlikli ve yaşanabilir mekânlar haline getirilmesi çabaları olarak ortaya çıkmaktadır. Bu çalışma, kentsel dönüşüm projelerinin tasarlanması ve uygulanmasına yönelik farklı örnekleri değerlendirerek, kent yöneticileri ve plancıları için kentsel dönüşüm sürecinin kavranmasına yönelik pratik bir araç oluşturmak üzerine kurgulanmıştır. Makale iki bölümden oluşmaktadır. İlk bölüm kentsel dönüşüm sürecini kapsam belirleme, planlama, finansman ve uygulama olmak üzere 4 aşama ile dünya örnekleri üzerinden tariflemektedir. Bu araştırmalar sonucunda kentsel dönüşüm sürecinde nasıl bir yol izlenebildiğine yönelik çıkarımlar oluşturulmuştur. İkinci bölümde ise ilk bölümde aktarılan aşamalar, Konya Kenti tarihi kent merkezi kentsel dönüşüm sürecinde ele alınarak deneyimler tartışılmıştır. Sonuç olarak, Konya kentsel dönüşüm deneyiminde kendine ait bir süreç oluşturduğu ve uygulama ve finansman aşamalarında eksikliklerin olduğu tespit edilmiş ve buna yönelik öneriler aktarılmıştır.
Konut ve Konut Çevresinin Kalitesini Belirleyen Faktörlere İlişkin Kullanıcı Önceliklerinin İncelenmesi: Konya Örneği
(2023) Levend, Sinan; Sağ, Mehmet Akif
Türkiye’de yapılı çevrenin oluşumunu, başta inşaat sektörüne hâkim olan yatırımcılar olmak üzere diğer aktörler arasındaki siyaset yönlendirmektedir. Bu durum konut üretim sürecinde insanların ihtiyaç ve önceliklerinin göz ardı edilmesine neden olabilmektedir. Diğer taraftan sürdürülebilir ve yaşanabilir yapılı çevre üretmenin temel koşulu katılımcı bir yaklaşım benimsemektir. Bu çerçevede çalışmanın amacı insanların konut ve konut çevresinin kalitesini belirleyen faktörlere ilişkin önceliklerini belirlemek ve COVID-19 salgınının insanların tercihleri üzerindeki etkisini anlamaktır. Çalışmanın örneklem alanı olan Konya kent merkezinde, COVID-19 öncesi ve sonrası olmak üzere iki ayrı dönemde nicel veriler toplanmıştır. Veriler Analitik Hiyerarşi Süreci (AHP) yöntemi kullanılarak analiz edilmiştir. Araştırmanın bulgularına göre, katılımcılar için mahremiyet ve güvenlik faktörleri, konut ve konut çevresinin kalitesini belirleyen en önemli unsurlardır. Bununla birlikte katılımcılar yapılaşma tipi olarak az katlı yapıları ve site tipi yapılaşmayı öncelemektedir. Ayrıca katılımcılar, güvenlik açısından komşuluk olgusuna dayalı sosyal kontrol mekanizmasının, güvenlikli-korunaklı sitelere göre daha öncelikli olduğunu düşünmektedir. COVID-19 salgınının insanların konut ve konut çevresinin kalitesini belirleyen faktörlere ilişkin önceliklerini etkilediği ancak etkinin sınırlı olduğu bulunmuştur. Salgın sürecinde yaşanan travma, gelecekte ortaya çıkabilecek olağanüstü durumlara karşı daha dayanıklı yaşam çevreleri oluşturma ihtiyacını ortaya koymaktadır.

Morphological Structures of Historical Turkish Cities
(2019) Topçu, Mehmet
In this study, morphological structures of the traditional fabrics of cities in Turkey, which have been shaped under the influence of various different cultures and geographical and climatic conditions in the historical process are presented via a mathematical interpretation. In this scope, spatial configuration and morphological structures of the historical cores of a total of fourteen cities selected from the seven geographical regions of Turkey, two cities from each (from the Marmara Region, Edirne and Bursa; from the Black Sea Region, Kastamonu and Trabzon; from the Central Anatolia Region, Sivas and Kayseri; from the Eastern Anatolia Region, Kars and Erzurum; from the Aegean Region, Muğla and Kütahya; from the South Eastern Anatolia Region, Urfa, Mardin and lastly from the Mediterranean Region, Tarsus and Antakya) region were analyzed comparatively using the Space Syntax method. In this method, the cities were analyzed in three main categories using eleven different parameters. These categories are convex space, axial space and syntactic space. Convex space analyzes were made using the paramters of convex articulation, convex deformation of the grid, grid convexity and convex ringness; axial space analyses were made using the paramters of axial articulation, axial integration of convex space, grid axiality and axial ringness; finally, syntactic space analyses were made using the parameters of integration, intelligibility and synergy. In conclusion, it could be said that historical fabrics of the cities in Turkey have synchronous structures, manifest regular reflections, have organic systems compared with the grid systems, and constitute higher intellibility and synergy.

Neo-Liberal Urbanism and Sustainability in Turkey: Commodification of Nature in Gated Community Marketing
(SPRINGER, 2021) Korkmaz, Cansu; Meşhur, Havva Filiz
Neoliberalism arose as a project to reinforce the power of capitalism against the working class in the post-1970 period and created unequal geographies as well as unearned income-oriented urban development practices in which the capital-owning class is operative. As in many other countries, urbanization and the construction sector have been used as important powers in Turkey in absorbing the plus value created by capitalism. After 1980, with the influence of the perspective towards the construction sector and the housing policies of Turkey, luxurious gated communities' production started in metropoles. In an environment of increasing competition, these housing projects started to present nature as a commodity by referring to projects' concepts such as natural life, sustainable environment, eco-friendly, etc. however, in contrast, the living environments they create. This paper aims to evaluate the physical and urban sustainability performances of luxurious gated communities that emphasize natural life and present nature as a commodity by emphasizing natural life and sustainable living environments in Konya by using an indicator-based approach. Even though these new living environments claim to create a sustainable and natural living environment and be eco-friendly projects, it can be seen after the evaluation results that they cannot go further than presenting nature as a commodity. In fact, in this capitalist system, while the construction sector destroys nature, it aims to increase the sales rates of the projects by making use of people's longing for nature.
A Place-Based Crime Prevention Through Urban Design: the Case of Sahibata Neighborhood in Konya
(International Design and Art Journal, 2022) Faizy, Matiullah; Topçu, Kadriye
People have the right to live in a safe environment free from crime and fear of crime with the most basic social needs. Although the subject has many different dimensions, this study evaluates it from a spatial perspective. The main aim of the study is to determine whether urban design is effective in reducing crime and fear of crime in urban spaces. For this purpose, firstly, place-based theories were investigated and a total of 12 effective design factors in producing safer spaces were revealed. Secondly, these factors were tested by visual observations and a total of 109 surveys with the users of the Sahibata neighborhood which has the highest crime rate in the city. While the visual observations were interpreted by photographs, the derived survey data were interpreted by using frequency and crosstab analysis. In conclusion, besides producing some spatial strategies such as revitalizing the lost spaces, increasing the lighting level, providing activity generators, variety of functions, decreasing the acts of vandalism signs and providing legibility and belonging clues in the sample area, it was emphasized that urban design is effective in minimizing crime and fear of crime, but it cannot be a single tool and it is necessary to evaluate the issue in the long term in all its other dimensions.

Processing of Anode Slime With Deep Eutectic Solvents as a Green Leachant
(ELSEVIER, 2021) Topçu, Mehmet Ali; Kalem, Volkan; Rüşen, Aydın
This paper describes an efficient process of recovering valuable metals from a copper anode slime sample using green chemicals such as choline chloride (ChCl) based deep eutectic solvents (DESs). The leaching agents include ChCl-urea, ChCl-ethylene glycol, ChCl-urea-ethylene glycol and ChCl/urea-deionized water in a 1:2, 1:2, 1:0.5:1.5, and 1:1 ratio, respectively. Prior to leaching experiments, chemical and mineralogical characterization of copper anode slime was performed. Considerable amount of precious metals was detected in the copper anode slime by chemical analysis. The main phases of copper anode slime detected by XRD and SEM/EDX analysis were namely Cu2O, SnO2, and, PbSO4. After leaching experiments, 97% of copper was recovered from the copper anode slime using ChCl-urea under an optimum condition at 95 degrees C of reaction temperature, 4 h reaction duration and, 1/25 g/mL solid/liquid ratio. The results showed that 91% of silver was extracted from the anode slime under the optimum condition with ChCl-urea DES composition, 95 degrees C reaction temperature, 48 h reaction duration, and 1/10 solid/liquid ratio. Gold was not leachable in the experiment using ChCl based DES with hydrogen bonding reagents such as urea and ethylene glycol. Moreover, the results revealed that PbSO4 was very soluble in DES prepared by ChCl and urea.
Rural Areas as Resilience Spaces in New Regional Development Paradigms: a Research in Case of Rural Areas of Beysehir in Konya
(Istanbul Univ, Fac Letters, Dept Geography, 2021) Karakayacı, Özer; Keser, Firuze
This study was aimed at evaluating the concept of resilience to rural areas in the new regional development paradigms. Rural resilience supported by evolutionary economic geography is considered the method developed against the negativity and practices emanating in the past that mired rural areas. The primary goal of this study, according to this framework, is to investigate the new significance that has been accorded to rural regions because of the paradigm shift. Furthermore, the study's major goal has been determined to be to offer assessments on sample areas on how the development dynamics in favor of cities can find resonance in rural areas. The factors affecting resilience are determined according to economic, ecological, and cultural contexts, and the role of rural areas in the settlement systems in the case of Beysehir are re-discussed. The findings of the study, which employed qualitative analytical methodologies, are expected to provide guidance for future studies on how the challenges highlighted within the framework of the idea of rural resilience will disclose a value chain in terms of rural settlements. Because rural resilience is defined as a rural area's ability to adjust to external situations based on changing living standards, it is more than just the ability to adopt change. Finally, with elements such as local skills and path dependences, it is now possible to prevent the decline of the Beysehir rural areas.

A Simulation-Based Accessibility Modeling Approach To Evaluate Performance of Transportation Networks by Using Directness Concept and Gis
(KONYA TECHNICAL UNIV, FAC ARCHITECTURE & DESIGN, 2019) Ertuğay, Kıvanç
Ranging from simple to sophisticated, numerous types of accessibility measures are found in the accessibility modeling literature which helps to understand accessibility of people, place and transportation networks. Transportation network directness (reciprocal is circuity), which is defined as the ratio of the shortest Euclidean distance over network distance between demand (origin) and destination (supply) points, could be considered as an important type of measure for understanding accessibility for a variety of context. Although there are several research and literature on transportation network directness and accessibility modeling, the research that integrates transportation network directness concept into accessibility modeling process in such a way to provide understanding of the overall accessibility performance of the transportation networks without losing the local interactions is quite limited. Based on this idea, the basic aim of this research is to propose a new transportation network directness-based accessibility modeling methodology that could be used to test both the local and the overall accessibility performance of transportation networks in a simple and comparable manner by using GIS. By considering regularly produced virtual origins and destinations on the transportation network in a simulation manner, the proposed methodology could produce travel time/distance based accessibility measures that could operate without a need for real time supply/demand or origin/destination data. The advantage of using a virtual regular data set instead of real time data is that; it is more simple, easy to operate and most importantly, more realistic to understand performance of transportation networks as most of the possible origin/destination scenarios could be represented in the proposed model. The outputs of the model could be widely used by the decision-makers who are supposed to deal with accessibility, location/allocation, and service/catchment area related issues by several aims such as; to test the overall/partial performance of the transportation networks, to understand the weakly connected parts of the transportation network and/or to compare the accessibility performance of different networks with each other. The proposed methodology is applied in 3 cities with different types of transportation network which are Paris, FRANCE (radial network); San Francisco, USA (grid network) and Ankara, TURKEY (mixed network) in order to able to demonstrate the performance and efficiency of the proposed model. The main focus of the case study is not to evaluate specific accessibility conditions or transportation network performance in a detailed manner but to provide a methodological discussion about the proposed directness based accessibility modeling process.
