Kentleşmeyle birlikte kentsel nüfus yoğunluğu da artmakta, bu da kentsel mekanlar üzerindeki baskıyı artırmaktadır. Kentlerde yaşam kalitesi bağlamında yeşil alanların önemli bir yeri bulunmaktadır. Bu alanlar kente ve kent insanı birçok yarar sağlamakta olup, Covid-19 sürecinde açık ve yeşil alanların değeri daha fazla anlaşılmıştır. Çoğu durumda bu yararlar nitel olarak ifade edilirken, son yıllarda yeşil alanların sağladığı yararların nicel ifadesi de ön plana çıkmaktadır. Yeşil alanların bir ekonomik yarar da sağladığının kamuoyu tarafından bilinmesi ve bu yararın parasal olarak ifadesi, bu alanlara yönelik bakış açılarında yeni fırsatlar sunmaktadır. Yeşil alanların sağladığı ekosistem hizmetlerinin ekonomik değerinin hesaplanması konusunda pek çok yöntem ve program geliştirilmiştir. Bu çalışmada, Amerika Birleşik Devletleri Tarım Bakanlığı (USDA) Orman Servisi tarafından geliştirilen ve ABD’de yaygın olarak kullanılan i-Tree programı ele alınmaktadır. I-Tree, kentsel ve kırsal orman analizi ve yarar değerlendirme araçları sağlayan son teknoloji ürünü bir yazılım paketidir Bu çalışmada, i-Tree programı kullanılarak yapılan çalışmalardan örnekler verilmekte ve hem uluslararası hem de ulusal çalışmalarda i-Tree programının yaygın araçları anlatılmaktadır.

ESTIMATING THE ECONOMIC VALUE OF GREEN SPACES THROUGH I-TREE PROGRAM

Öz

With urbanization, urban population density increases leading to the pressure on urban spaces. Green areas have an important place in the context of quality of life in cities. These areas provide many benefits to the city and its people, and the value of open and green spaces has been understood more during the Covid-19 period. While in most cases these benefits are expressed qualitatively, in recent years the quantitative expression of the benefits provided by green areas has also come to the forefront. The public knowledge that green areas also provide economic benefits and the monetary expression of this benefit offer new opportunities in the outlook towards these areas. Many methods and programs have been developed to estimate the economic value of ecosystem services provided by green areas. In this study, the i-Tree program, developed by the United States Department of Agriculture (USDA) Forest Service and widely used in the USA, is discussed. I-Tree is a state-of-the-art software package that provides urban and rural forest analysis and benefit assessment tools. In this article, examples of studies using the i-Tree program are given and common tools of the i-Tree program in both international and national studies are described.
