Abstract

Analytical tools are necessary instruments used in the integration of impact assessment systems into decisionmaking processes in order to give appropriate decisions. The techniques using at assessment stages may vary according to scope and scale of the studies. The reliability of impact predictions will ensure that the assessment in the following stages is objective and comparable. Within the scope of this study, an examination is conducted on the applicability of the Delphi technique, which is one of the analytical tools used in impact assessment processes. Within this context, firstly, it is examined the conceptual and technical features of impact assessment systems and Delphi technique in detail. The information gathered directly from the source provided guidance on how and at which stages the Delphi technique need to be applied to impact assessment processes. As a conclusion, it is highlighted the importance of analytical tools and the necessity of using them effectively, especially within the scope of the integration of SEA processes with sectoral planning processes.

Etki değerlendirme süreçlerinde kullanılan analitik araçlar kapsamında Delphi tekniğinin uygulanabilirliği

Abstract

Etki değerlendirme sistemlerinin karar verme süreçlerine entegrasyonunda farklı analitik araçlardan yararlanmak, etkin kararlar üretebilmek adına önemli bir gerekliliktir. Kullanılan değerlendirme teknikleri ilgili çalışmanın kapsamına ve ölçeğine bağlı olarak değişkenlik gösterebilir. Etki değerlendirme süreçlerine yönelik öngörülerin doğruluğu, ilerleyen aşamalardaki değerlendirmenin objektif ve karşılaştırılabilir nitelikte olmasını sağlayacaktır. Bu çalışma kapsamında, etki değerlendirme süreçlerinde kullanılan analitik araçlar arasında yer alan Delphi tekniğinin uygulanabilirliği üzerine bir inceleme yürütülmüştür. Bu kapsamda, öncelikle etki değerlendirme sistemlerinin ve Delphi tekniğinin kavramsal ve teknik altyapısı irdelenmiştir. Elde edilen bulgular, Delphi tekniğinin etki değerlendirme süreçlerine uygulanmasının hangi aşamalarda ve nasıl olması gerektiği ile ilgili yol gösterici olmuştur. Çalışmanın sonucunda, etki değerlendirme sistemleri kapsamında, özellikle stratejik çevresel değerlendirme (SÇD) süreçlerinin sektörel planlama süreçleri ile entegre yürütülmesi kapsamında analitik araçların önemine ve etkin kullanılması gerekliliğine dikkat çekilmiştir.
