    Coastal flood risk analysis using landsat-7 ETM+ imagery and SRTM DEM: A case study of Izmir, turkey
    (Springer, 2007) Demirkesen, A. C.; Evrendilek, F.; Berberoglu, S.; Kilic, S.
    The Intergovernmental Panel on Climate Change (IPCC) reports an acceleration of the global mean sea-level rise (MSLR) in the twentieth century in response to global climate change. If this acceleration remains constant, then some coastal areas are most likely to be inundated by the year 2100. The ability to identify the differential vulnerability of coastlines to future inundation hazards as result of global climate change is necessary for timely actions to be taken. Yildiz et al. (Journal of Mapping, 17, 1 75, 2003) reported that the local MSLR in the city of Izmir rose at a rate of 6.8 +/- 0.9 mm year(-1) between 1984 and 2002. In this study, the spatial distribution of the coastal inundation hazards of Izmir region was determined using not only land-use and land-cover (LULC) types derived from the maximum likelihood classification of Landsat-7 Enhanced Thematic Mapper Plus (ETM+) multi-spectral image set but also the classification of the digital elevation model (DEM) acquired by the shuttle radar topography mission (SRTM). Coastal areas with elevations of 2 and 5 m above mean sea-level vulnerable to inundation were found to cover 2.1 and 3.7% of the study region (6,107 km(2)), respectively. Our findings revealed that Menemen plain along Gediz river, and the settlements of Karsiyaka, Alacati, Aliaga, Candarli and Selcuk are at high risk in order of decreasing vulnerability to permanent and episodic inundation by 2100 under the high MSLR scenarios of 20 to 50 mm year(-1).

    Environmental monitoring of land-use and land-cover changes in amik plain, Turkey
    (International Society for Photogrammetry and Remote Sensing, 2004) Kilic, S.; Evrendilek, F.; Berberoglu, S.; Demirkesen, A.C.
    Unprecedented rates of changes in land use/cover (LULC) on the local and regional scales lead to alterations of global biogeochemical cycles, and loss of productive ecosystems and biodiversity. Driving forces behind LULC changes mainly include rapid growth rates of population and consumption, lack of valuation of ecological services, poverty, ignorance of biophysical limitations, and use of ecologically incompatible technologies. One of the major ecological tragedies of the commons in the province of Hatay is the case of the loss of the Amik Lake, which reveals the urgent need for adoption of sustainable and adaptive ecosystem management strategies if escalating land use conflicts are to be avoided and environmental degradation is to be reversed in the Amik plain of the southeastern Mediterranean region of Turkey. In the 1940s, the Amik lake was started to be discharged into the Orontes river by a large-scale campaign launched to increase the area of croplands. The study quantified LULC changes and explored constraints and opportunities for future LULCs in the study area. Land use/cover changes were detected from a time series of satellite images of Landsat-MSS in 1972, Landsat-5 TM in 1987, and Landsat-7 ETM+ in 2000 using remote sensing and geographic information systems (GIS). The study revealed that the increase in croplands between 1972 and 1987 took place at the expense of the irreversible losses of the Amik lake and its related wetlands of over 53 km2 used to provide vital ecosystem goods and services for the region. In the period of 1972 to 2000, croplands, settlements, and evergreen forests increased by 174%, 106%, and 14%, respectively, in parallel to the decreases in shrublands-orchards, and bareground. The increase in settlements occurred mostly to the detriment of croplands. The prospects for halting environmental degradation and destruction, rehabilitating damaged ecosystems, and developing sustainable ecosystem management practices need to be dealt with in light of the institutional and economic constraints facing Turkey.
