Bamako’da Kentsel Yayılma ve Arazi Kullanım Değişimi (1975–2023): Uzaktan Algılama ve CBS Analizi

Abstract

Bu çalışma, 1960 Bağımsızlık Bildirgesi'nden 2023'e kadar Bamako, Mali'deki arazi kullanımı ve arazi örtüsü (LULC) değişimini ve kentsel yayılmayı incelemek için uzaktan algılama ve CBS tekniklerini kullanmaktadır. Araştırma, kentleşme ve kentsel yayılma modellerine dair güncel bir bakış sunmakta ve LULC değişimi ile kentsel form arasındaki bağlantıya odaklanmaktadır. Hiyerarşik sınıflandırma, zaman serisi analizi, nüfus istatistikleri ve dijital uydu görüntü analizini içeren çok yöntemli bir yaklaşım benimsenmiştir. Sonuçlar, 1985'ten sonra yapılaşmanın arttığını ve özellikle Nijer Nehri'nin sağ kıyısında yer alan yemyeşil bitki örtüsüne sahip bakir bölgelere doğru genişlediğini göstermektedir. 2000-2023 arasında, gecikmiş mekânsal planlama ve arazi kullanımı ulaşım politikaları arasındaki entegrasyon eksikliği nedeniyle yapılaşma ve bitki örtüsünde önemli değişimler gözlemlenmiştir. Kentin her yöne doğru genişlemesi, süregelen büyümeyi işaret etmekte ve kentsel yayılmayı planlama zorluklarıyla kontrolsüz gelişime bağlamaktadır. Çalışma, Bamako ve çevresinin uzun vadeli sürdürülebilirliği için entegre arazi kullanım planlamasının önemini vurgulamaktadır.

Urban Sprawl and Land Use Change in Bamako (1975–2023): A Remote Sensing and GIS Analysis

Abstract

This study uses remote sensing and GIS techniques to investigate land use and land cover (LULC) change and urban sprawl in Bamako, Mali, from 1960 to 2023. The research aims to address gaps in the existing literature by providing an up-to-date view of urbanization and urban sprawl patterns and focusing on the link between LULC change and urban form. A multi-method approach was adopted using hierarchical classification, time series analysis, population statistics, and digital satellite imagery analysis. Results show that built-up areas began to rise after 1985, expanding into untouched regions, especially on the right bank of the Niger River. Significant changes in built-up areas and vegetation cover were noted between 2000 and 2023, attributed to delayed spatial planning and a lack of integration between land-use and transportation policies. The study highlights the importance of integrated land use planning for the long-term sustainability of Bamako and its surroundings.
