Kentlerde Biyofilik Tasarım ve Mekansal Adalet İlişkisi: Mahalle Parkları Deneyimi

Günümüzde kentsel planlamada doğa ve doğal çevreyi öne çıkaran ve kentleşmenin doğallaştırılması olarak gündeme gelen yaklaşım biyofilik tasarım ve planlama yaklaşımıdır. Biyofilik yaklaşımlar, doğal veya yapay açık-yeşil alan, doku ve parçaların kentsel doku içerisindeki yüzdesinin artırılması ve ayrıca bireylerin bu alanlara erişiminin ve alan deneyimlerinin en yüksek seviyeye çıkartılmasını amaçlamaktadır. Bu çalışmanın ana argümanı, kent bütünde makro ve üst ölçek planlama ve dönüşüm müdahaleleri yerine mikro-müdahaleler ile yerel ölçekten başlayan çözümlerin keşfedilerek ön plana çıkartılmasıdır. Yerelde yapılan müdahaleler ile kent bütününde entegrasyonun artacağı ve ulaşım bağlantılarının kuvvetleneceği öngörülmektedir. Yerel ölçek olarak mahalle ve konut çevresi ölçeğine odaklanan çalışma, mahalle parklarının erişilebilirliği ve olası park bağlayıcı ağların keşfini nokta tabanlı erişilebilirlik yaklaşımı ile ele almıştır. Bu analitik mekansal yaklaşımın operasyonel hale gelmesi veri temelli model tasarımı şeklinde kurgulanmıştır. Mevcut mekansal veriler kullanılarak CBS veritabanı oluşturulmuş, CBS yazılımı olarak ArcMap 10.5 ve network ağ analizleri kullanılmıştır. Çalışma alanında bulunan mevcut park alanlarının erişilebilirliği, network (gerçek mesafe) tabanlı çalışan servis analizi kullanılarak hesaplanmıştır. Park alanlarının maksimum 500m içindeki erişim hatları hesaplanmıştır ve böylece alandaki konut birimlerinin (en kısa) hangi mesafede bir park alanına eriştiği ortaya konulmuştur. Yapılan analizler sonucunda, mevcut parkların ortalama 300m içerisinde erişim sağlandığı görülmüştür. Fakat bazı konut birimlerinin 500m içerisinde bir park alanına erişemediği tespit edilmiş, bu nedenle park alanlarına erişimi arttırmak için mevcut yapılaşmamış alanlarda yeni park alanları ile birlikte Meles deresini bağdaştırıcı bir unsur olarak canlandırmak için yaya odaklı akslar önerilmiştir. Bunlar, park alanlarını ve su öğesini kapsayan yaya öncelikli akslar olarak nitelendirilebilir. Bu sayede hem yeşil alan entegrasyonu iyileştirilmiş hem de mekansal adalet duygusu kuvvetlendirilmiştir.

The Relationship between Biophilic Design and Spatial Justice in Cities

Biophilic design as a planning approach emphasizes nature and the natural environment in urban planning and is called as ‘naturalization of urbanization’. Biophilic approaches to urban planning aim to increase the percentage of natural or artificial open-green spaces in the urban fabric, and to maximize the accessibility of and beneficial experience in these areas. The main argument of the study is to focus on micro-scale spatial interventions and solutions starting from the local scale instead of macro and upper scale transformation and interventions in cities. It is acknowledge that the interventions at local spatial levels may increase the integration and connection with upper levels in cities. The study focuses on neighborhood scale, measuring the accessibility of neighborhood parks and searching for park linking networks using a point-based accessibility approach. The operationalization of the analytical spatial approach has been designed in the model of data-based design. A GIS database is created using spatial data of existing urban environment, using ArMap 10.5 and network analysis as a GIS software. The accessibility of existing parks in the study area is calculated using network (actual distance) based service area analysis. Access lines via streets within a maximum of 500m walking distance to parks are calculated that is revealing what is the walking distance between residences and closest parks. As a result of the analysis, it is seen that the existing parks are accessible within 300m on average. However, it is observed that some residential units could not access any park area within 500m walking distance. New parks are proposed in existing urban voids to increase accessibility to parks. Therefore, 9 new park areas are proposed to increase accessibility and pedestrian-oriented routes are proposed to revive the Meles river as a connecting natural element. By means of new routes and parks, the green space integration and the sense of spatial justice will be both strengthened.
