![]() ![]() (2018) used aerial photographs obtained in 19 and Landsat images collected in 19 to analyze the historical LULC changes in the central Ethiopian highlands 19. They stated that the LULC exhibits differences in vegetation densification for different periods, and agricultural abandonment was dominant between 19, parallel to socio-economic changes. Their results illustrated that the post-war need for agricultural production caused LULC changes within the Aetoloakarnania region. (2017) determined post-World War II LULC change in Greece applying photo interpretation methods to aerial photographs obtained between 19 18. Popelková and Mulková (2018) conducted a multi-temporal analysis of land cover change in a coalfield in today’s Czech Republic between 18 using cadastral maps and ortho-photos 17. Aerial imagery and historical cadastral maps have also been used to characterize the landscape dynamics. Many researchers have analyzed the pattern of LULC changes by using multi-temporal satellite images 7– 16. Accurate mapping of current and past land surface conditions is crucial to provide reliable geo-information for modeling the land changes, to deliver reliable inputs for different environmental models, and to develop precise decision-support systems for multi-disciplinary applications 7.Ĭreating current high-resolution LULC maps became widespread with the increased availability of different satellite images and numerous image processing approaches. A long-term perspective to understand these and other crucial forms of LULC changes is necessary. Rural depopulation is becoming a central theme of research impacting both demography as well as land use 6. Deforestation as a form of land cover change is proven to be directly linked to soil erosion and climate change 5. In 2018, it was forecasted that between 20, about 11% of agricultural land in the European Union would be under high potential risk of abandonment 4. ![]() Understanding the spatio-temporal distribution, patterns, and impacts of landscape change is essential for the sustainable management of the Earth's resources 1– 3.Īgricultural land abandonment, de- and/or afforestation, and rural depopulation are acute challenges worldwide. Land surface has been changing significantly due to natural and anthropogenic effects, causing variations in land use and land cover (LULC) characteristics of the corresponding regions. ![]() Global environmental change is a critical issue causing climate change, land degradation, and biodiversity loss. We observed rural depopulation and gradual afforestation in Aksu whereas, agricultural land abandonment and deforestation in Kestel. Also, our quantitative analysis of LULC maps indicates diverging developments for the selected locations in the long period of 162 years. Our approach minimized the amount of manual digitizing required for the boundary delineation of LULC classes from historical geospatial data. We propose methods to facilitate the preparation of historical datasets for the LULC change detection and present an object-oriented joint classification scheme for multi-source datasets to accurately map the spatio-temporal changes. We investigated two pilot regions, Aksu and Kestel towns in Bursa/Turkey, to analyze the long-term LULC changes quantitatively and to understand the driving forces that caused the changes. This study aims to determine historical land use and land cover (LULC) changes using multi-modal geospatial data, which are the cadastral maps produced in 1858, monochrome aerial photographs obtained in 1955, and multi-spectral WorldView-3 satellite images of 2020. Accurate representation of landscape characteristics and precise determination of spatio-temporal changes provide valuable inputs for environmental models, landscape and urban planning, and historical land cover change analysis. Land surface of the Earth has been changing as a result of human induced activities and natural processes. ![]()
