Land Use Trends During Rapid Urbanization of the City of Aydin, Turkey

This study assessed land cover (LC) changes in Kahramanmaraş (K.Maraş) and its environs by using multitemporal Landsat and ASTER imagery, respectively belong to 1989, 2000 and 2004. A priori defined nine land cover classes in the classification scheme were urban and built-up, forest, sparsely vegetated areas, grassland, vegetated stream beds, unvegetated stream beds, bare areas, crop fields, and water bodies. Individual classifications were employed using the combination of both unsupervised and supervised classification methods. Iterative Self Organizing Data Analysis (ISODATA) was used to reduce spectral variation in the scenes arising from complex pattern of crop fields. Maximum Likelihood classifier was used in the LC classification of the individual images. Image pairs of consecutive dates were compared by overlaying the thematic LC maps and cross-tabulating the LC statistics. Urbanization and expansion of agriculture were the major reasons for the dramatic LC conversions. The amount of conversion from crop fields to water occurred as large as 927.67 ha, accounting for 73% of the total land-to-water conversion. Conversions to agriculture have mainly been occurred from grasslands and sparsely vegetated areas as large as 1,314.95 and 1,325.84 ha, respectively. Urban coverage doubled in this period as a result of 1,443.45 ha of increase. Urban area increased in the second period from 2,920 to 3,526 ha. Conversions to agriculture occurred at high amounts. A total of 1,075.79 ha area changed from sparsely vegetated areas to crop fields. A landscape-level environmental monitoring scheme based on satellite remote sensing was proposed for effective environmental resource management.

“…For example, throughout the Mediterranean region, 3% of farmland was lost to urbanization in the 1990s, and 60% of this land was prime farmland (EEA 2006). Turkey has also been subject to land transformations into urban-industrial land uses, especially with the loss of fertile agricultural lands to urbanization (Evrendilek and Doygun 2000;Eşbah 2007;Doygun et al 2008).…”

The main objective of this study is to quantify areal loss of olive groves due to urban sprawl of the city of Kahramanmaraş, Turkey. Spatial changes were analysed by interpreting the digitized data derived from a black-white monoscopic aerial photograph taken in 1985, panchromatic IKONOS image of 2000 and two pan-sharpened Quickbird images of 2004 and 2006. Data obtained revealed that the area of olive groves decreased by 25% from 460.55 ha in 1985 to 344.46 in 2006, while the number of parcels increased from 170 to 445. Of the total areal loss, 60% was due to building constructions, with the rest being due to clear-cut for new residential gardens composed of exotic plants, new buildings, or new roads. Rapid population growth, increased land prices due to urban expansion, and abandonment of agricultural practices to construction of multi-storey buildings were the main causes of the process that transformed the olive groves into urbanized areas. Results pointed to an urgent need to (1) revise the national and municipal land management practices, (2) balance the gap between the short- and long-term economic benefits that urban and community development plans ignore, and (3) monitor land-use changes periodically by using high resolution satellite images.

“…The subjects of study that characterize landscape ecological research carried out in urban areas are, in order of the proportion of the papers reviewed here devoted to them, land use/land cover change over time (27%), the ecological effects of land use type (8%), disturbance (7%), human‐made habitats (3%), and the ecological effects of land use pattern (0.4%) (Table ). The land use/land cover change literature included papers that described change over time (e.g., Esbah ), calculated rates of change (e.g., Seto and Fragkias ), identified the drivers of change (e.g., Gustafson et al ), estimated the ecological impacts of land use/land cover change (e.g., Robinson et al ), or simulated past and future change, typically with the use of cellular automata models (Sante et al ).…”

The urban transformation of the planet has spurred interest across a wide variety of disciplines in the fundamental changes to human society and the environment that result from urbanization. Landscape ecology is no exception. Since the late 1980s, the number of papers devoted to the study of the ecology of urban landscapes has risen dramatically. This trend prompted the question I address in this paper: what are the distinguishing features of the study of the ecology of urban landscapes? To answer this question, I reviewed 894 papers, published between 1987 and 2011, describing the ecology of urban terrestrial landscapes. Landscape ecologists who study urban landscapes use the gradient paradigm and the urban ecosystem framework to shape their research questions. They study subjects such as land use/land cover change, the ecological effects of land use type and pattern, and human‐made habitats that receive less attention from landscape ecologists studying non‐urban areas. They also study a very wide variety of disturbances that occur in urban landscapes. And, increasingly, they are making use of citizen‐generated data to answer their questions. Knowledge of the ecology of urban landscapes is largely based on comparisons of land use types, investigations along the urban gradient, and research centered on remnant habitat fragments in an urban matrix. Future directions for the study of the ecology of urban landscapes include testing whether understanding derived in less modified landscapes can be applied to intensively modified urban landscapes, investigating the interactions between agents of global change, such as climate change, and urbanization, investigating the effects of matrix quality on the biodiversity of habitat fragments, expanding our understanding of the ecological effects of land use pattern, and assessing the trade‐offs between human needs and the needs of other species by means of transdisciplinary collaborations.
