“…Given the scale of the growth, neither local nor the central governments have shown capability of controlling the influx of migrants, most of which settled illegally on public lands creating low quality low cost housing and industrial environments. Most of the settlements lack the basic sewerage facilities, and a significant portion of which are on the river system (Kücükmehmetoglu and Geymen 2006).…”

The effect of land cover change, from natural to anthropogenic, on physical geography conditions has been studied in Kayisdagi Mountain. Land degradation is the most important environmental issue involved in this study. Most forms of land degradation are natural processes accelerated by human activity. Land degradation is a human induced or natural process that negatively affects the ability of land to function effectively within an ecosystem. Environmental degradation from human pressure and land use has become a major problem in the study area because of high population growth, urbanization rate, and the associated rapid depletion of natural resources. When studying the cost of land degradation, it is not possible to ignore the role of urbanization. In particular, a major cause of deforestation is conversion to urban land. The paper reviews the principles of current remote sensing techniques considered particularly suitable for monitoring Kayisdagi Mountain and its surrounding land cover changes and their effects on physical geography conditions. In addition, this paper addresses the problem of how spatially explicit information about degradation processes in the study area rangelands can be derived from different time series of satellite data. The monitoring approach comprises the time period between 1990 and 2005. Satellite remote sensing techniques have proven to be cost effective in widespread land cover changes. Physical geography and particularly natural geomorphologic processes like erosion, mass movement, physical weathering, and chemical weathering features etc. have faced significant unnatural variation.

“…Lack of planning was not the only reason for such uncontrolled development; the desperation of a society in transition from an agrarian economy to industrial one, and the inability of the government institutions in controlling these overwhelmingly rapid changes are also worth to inquiry (Kücükmehmetoglu and Geymen 2006).…”

“…Features such as industry, roads, unplanned/illegal settlements (which tend to have poor wastewater treatment), are mapped and quantified [131,133,134]. These urban land cover maps are used as inputs to model non-point source (NPS) nutrient loadings into local water sources [135]. Research results have led to recommendations on general watershed planning, such as which areas should receive high protection status and where to located water treatment plants [131].…”

This paper reviews how remotely sensed data have been used to understand the impact of urbanization on global environmental change. We describe how these studies can support the policy and science communities' increasing need for detailed and up-to-date information on the multiple dimensions of cities, including their social, biological, physical, and infrastructural characteristics. Because the interactions between urban and surrounding areas are complex, a synoptic and spatial view offered from remote sensing is integral to measuring, modeling, and understanding these relationships. Here we focus on OPEN ACCESSRemote Sens. 2014, 6 3880 three themes in urban remote sensing science: mapping, indices, and modeling. For mapping we describe the data sources, methods, and limitations of mapping urban boundaries, land use and land cover, population, temperature, and air quality. Second, we described how spectral information is manipulated to create comparative biophysical, social, and spatial indices of the urban environment. Finally, we focus how the mapped information and indices are used as inputs or parameters in models that measure changes in climate, hydrology, land use, and economics.

[27] study all of the basins in the Province of Istanbul by using Landsat GeoCover LC-1990 and 2000 satellite images, and conclude that in addition to the impacts of the capital improvement projects.…”

The population in Istanbul has been increasing as a result of mass immigration. An urbanization process continues and it causes serious increases in urban areas while decreasing the amount of natural environment. This uncontrolled and illegal urbanization accompanied by insufficient infrastructure has caused degradation of cropland and forested areas in the metropolitan area, especially in water basin area. The watershed basins inside the metropolitan area have accelerated the land-cover changes, which have negative impacts on water quality of the basins. The Terkos water basin, one of the seven water basins of Istanbul providing drinking water, was selected as a study area. In order to understand the effect of the land use change of the water basin in Istanbul Metropolitan Area, we used the three Landsat satellite images of the years 1995, 2005 and 2010. The study mainly focuses on the acquisition and analysis of Landsat TM satellite images reflecting the significant land-cover changes between the years of 1995 and 2010. The findings show that the settlement areas emerged mainly on the protection zones of the Terkos basin and created serious environmental problems. The land use change will effect precipitation change on direct surface runoff in water basin.
