“…One GIS-based indicator has been introduced for each of the three effects. This indicator evaluates the reduction of the population exposition to seismic risk as a positive effect of the regeneration actions [8]. It is calculated for each of the three considered buffers as the population that is not exposed to seismic risk with the following formula:…”

“…Furthermore, the method can also be improved by evaluating the concurrent effects of different combinations of RAs: this will allow the municipality to define scenarios of regeneration priority, in terms of which projects might be financed and implemented firstly because of their higher positive effect on the urban environment. Such scenarios will generate positive effects not only to the single areas to be regenerated but also to wider urban contexts [8], significantly reducing the urban exposure to seismic and climate change risks and at the same time producing more livable and healthy urban environment.…”

Topics of sustainable urban development and environmental sustainability are worldwide considered as fundamental for every strategy of urban transformation, renewal and regeneration. In particular, urban regenerations are urban re-development programs involving the rebirth or renewal of selected urban areas or district that have faced periods of decline due to compounding and intersecting pressures. The programs cover many aspects of the area to be re-generated such as physical, social and environmental contexts. Re-use of already built up areas and buildings, reduction of the demand for new soils to be developed, increasing of appealing of dense city areas, increasing of social and spatial resilience are among the positive consequences of these programs. However, in the current debate about urban regeneration, few studies have evaluated the real environmental outcomes and effectiveness of regeneration programs in terms of physical variables such as new provided greenspaces, accessibility to public transportation, climate change or seismic risk reduction. This paper proposes a method to quantify the real outcomes and effectiveness of urban regeneration programs with reference to the above mentioned variables. As a real experience of urban planning, the new Local Spatial Plan for the Municipality of Catania, a medium sized city in Southern Italy, is presented. The city is characterised by a high density urban fabric, a general lack of urban greenspaces and high levels of traffic congestion due to a massive use of private transportation. The urban fabric is also very vulnerable to seismic and climate change risks. Among the transformation tools, the new Local spatial plan proposes regeneration actions aimed at the complete regeneration of old and dilapidated areas, not classified as historical heritage and heavily vulnerable to seismic risk. These actions include the complete demolition and reconstruction of these areas within clearly defined boundaries, contributing to minimise soil consumption, maintaining as open public spaces the majority of existing non urbanised areas within the densely built-up settlement. The program of regeneration can dramatically contributes to the reduction of seismic and climate change risk and achieve a general requalification of the urban environment. Starting from this planning experience, this paper focus on the evaluation of the regenerations programs included in the Local Spatial Plan. Regeneration Areas (RAs) have been identified by the municipality as characterized by high level of seismic vulnerability, urban degradation, lack of public services and urban environment quality. For the chosen areas, this study proposes the evaluation of the transformations potentially occurring in the urban context by the proposed regeneration program. The following aspects are evaluated: -reduction of risks (in terms of exposition and vulnerability to seismic and climate change related risks)

“…Özellikle 1999 yılı öncesinde üretilen yapı stokunun büyük kısmının hem düĢük kaliteli ve depreme dayanıksız olduğu, hem de ekonomik ömrünü tamamladığı genel kabul görmektedir (Gunes, 2015;Gül & Bayram, 2014;KeleĢ, 2015). Büyük bölümü deprem kuĢaklarında yer alan ülkemizde belirli aralıklarla büyük depremler yaĢanmaktadır (Güzey, 2016).

Öz: Türkiye"de büyük kentlerde son 60 yılda ortaya çıkan düzensiz, kalitesiz ve ekonomik ömrünü tamamlamıĢ yapı stoğunun yenilenmesine ihtiyaç vardır. Ancak kentsel dönüĢüm projeleri, son derece büyük çaplı ve pahalı inĢaat projeleridir. Yetkili kamu kurumlarının bütün bir Ģehrin dönüĢümüne aynı anda baĢlaması teknik ve ekonomik açıdan mümkün değildir. Bu sebeple yürütücü kurumlar, herhangi bir Ģehirde, dönüĢümüne ihtiyaç duyulan birden fazla mahallenin bulunması durumunda, tüm mahallelerin dönüĢümüne aynı anda baĢlamaktan ziyade, projeleri bir sıraya koyarak en sorunlu ve acil olan mahalleden daha az aciliyete sahip olan mahallelere doğru yürütülmektedirler. Bu noktada uygulamayı yürüten kurumlar hangi mahallenin bir diğerinden daha önce dönüĢüme tâbi tutulması gerektiği kararını vermekte zorluk yaĢamaktadırlar. Verilen kararları da kamuoyuna açıklarken güçlük çekmektedirler. Bulanık Mantık yöntemiyle bilgisayarda hazırlanacak bir karar destek sistemi sayesinde kararların daha tutarlı verilmesi sağlanabilir. Ayrıca böyle bir sistemle verilen kararlar, belli bir bilimsel alt yapıya sahip olacağından, spekülasyonların önüne geçilebilecek ve kararlara bir meĢruiyet kazdırılması noktasında yardımcı olabilecektir. Bu çalıĢmada, kentsel dönüĢümde Bulanık Mantık yöntemi kullanılarak örnek bir karar destek sistemi tanıtılmaktadır.Anahtar Kelimeler: Kentsel dönüĢüm, Bulanık mantık, Öncelik sırası. Putting Urban Regeneration Projects in Order: An Example of a Decision Support SystemAbstract: There is an urgent need of renewal of metropolitan cities in Turkey which heavily consist of irregular, low quality building stock which have occurred in the last 60 years. However urban regeneration projects are large and expensive construction projects. Therefore , due to technical and economic barriers, it is not possible for regeneration authorities to s tart the projects for the whole city in the same time. Thus they carry out projects step by step, one after another. Projects are started from the most problematic and urgent ones to the least problematic ones. However, regeneration authorities face with problems when putting regeneration projects in order, i.e. determining which neighborhood should be regenerated earlier than the other one. In addition to that, they are having difficulties when explaining their decisions to the public. At this point, a computer-based Fuzzy Logic decision support system can help them reach more convenient decisions. Also, with this way, the decisions will have a scientific basis, therefore it can be easier to announce them to the public and avoid speculation. In this paper, an example of a decision support system based on Fuzzy Logic for putting urban regeneration project areas in order was presented.

ABSTRACT:In Turkey, rapid population growth, informal settlements, and buildings and infrastructures vulnerable to natural hazards are seen as the most important problems of cities. Particularly disaster risk cannot be disregarded, as large parts of various cities are facing risks from earthquakes, floods and landslides and have experienced loss of lives in the recent past. Urban regeneration is an important planning tool implemented by local and central governments in order to reduce to disaster risk and to design livable environments for the citizens. The Law on the Regeneration of Areas under Disaster Risk, commonly known as the Urban Regeneration Law, was enacted in 2012 (Law No.6306, May 2012). The regulation on Implementation of Law No. 6306 explains the fundamental steps of the urban regeneration process. The relevant institutions furnished with various authorities such as expropriation, confiscation and changing the type and place of your property which makes urban regeneration projects very important in terms of property rights. Therefore, urban regeneration projects have to be transparent, comprehensible and acceptable for all actors in the projects. In order to understand the urban regeneration process, the legislation and projects of different municipalities in Istanbul have been analyzed. While some steps of it are spatial data demanding, others relate to land values. In this paper an overview of the urban regeneration history and activities in Turkey is given. Fundamental steps of the urban regeneration process are defined, and particularly spatial-data demanding steps are identified.
