    Application of analytical hierarchy process and geographic information systems in land-use suitability evaluation: a case study of Dumrek village (Canakkale, Turkey)
    (Taylor & Francis Inc, 2009) Cengiz, Tuelay; Akbulak, Cengiz
    This study used both analytical hierarchy process (AHP) and geographic information systems (GIS) to make a land-use suitability analysis for the village of Dumrek, NW Turkey. Primarily, alternative land uses for agriculture, meadow-pasture and forest were determined along with criteria for these alternatives and a hierarchical structure was produced and used to determine the weights of the criteria. Spatial data were identified by means of GIS and calculations were made using the suitability values specified and weights obtained from AHP. Suitability maps were then produced for the above land use alternatives. Subsequently, a synthesized suitability map was formed from these maps. According to the weights specified by AHP, the order of land use preferences among the alternatives for rural development of Dumrek was agriculture, forest and meadow. The synthesized suitability map showed that the areas allocated for forest and agriculture were close to the present ratios of use; however, meadow land, which does not exist at present, should be allocated as a land use to constitute 12.5% of the study area. Achieving sustainability in land use is possible by planners and administrators considering results obtained from land suitability mapping studies at the stage of allocating land uses. The method applied in this research is considered useful when taking policy decisions covering the evaluation of rural land use, particularly for subunits of the state administration.

    Ecological approach in sustainable tourism: Savsat district example
    (Academic Journals, 2009) Cengiz, Tuelay; Caliskan, Erhan
    Unless the measures, envisaged for mass tourism in a sustainable understanding, are taken for ecotourism as well, ecotourism will be brought to the same point with mass tourism in terms of environmental hazard as a consequence of an increase in demand. Thus, it is fundamental to find out the level of environmental degradation of the resource and to form the potential for making use of nature-based tourism resources. In order to reduce physical effect in the area used, the relationship between tourism and conservation has to be analyzed in terms of ecological sustainability. Ecological tourism is based on the requirement of conserving resources while they are used. Being the subject to the research, the town of Savsat in Artvin has rich natural and cultural heritage. However, the area is damaged due to intensive touristic potential. In this sense, the use values and conservation values were taken as the basis in the research and the method of Kalem (2001) was applied. In order to determine the general use and conservation values of an area and its usable touristic potential, the criteria constituting the natural and cultural criterion were developed in the method. Natural and cultural elements were examined individually and values were appointed to the criterion report. In appointing these values, the thematic digital maps (the geographical location, transportation and settlement maps, soil map, geological map, presence of water, seismic activity and etc.), created by the GIS (Arcview 8.3) software for the features constituting each criterion report, were utilized. As a result of the research, the area's weighted use value put into to the percentage was determined as 69.9%, weighted conservation value as 48.7% and weighted usable touristic potential as 21.2%. The result got shows that the sources were not able to be protected adequately for sustainability while using them. In addition, natural and cultural properties which are crucial in the use of ecological sources and should be protected have been determined separately in the result of the research. Paying attention to these properties of sources, ecological tourism applications can be realized in the research area. It's considered that to open the research area, which has suitable potential for a variety of ecological tourism kinds, to tourism in the frame of sustainability principles in some phases will be useful in increasing the region's welfare level.

    The evaluation of festival activities in tems of conservation and usage in natural areas
    (Foundation Environmental Protection & Research-Fepr, 2008) Yuksek, Turan; Cengiz, Tuelay; Yuksek, Filiz
    The aim of this study is to evaluate some important environmental problems caused by festival activities in Artvin-Kafkasor area in terms of conservation-usage. For this purpose, an inventory was carried out in the festival area and surrounding region. Physical carrying capacity of study area was estimated between 3432 (min.) and 5750 (max.). During the festival, a total of 8607 people made entrance to the festival area. In the last day of the festival, 6400 people made entrance, which was more then the maximum carrying capacity of the festival area. During the festival, 2454 motor vehicles were registered and 360 tents were pitched, 60 of which belonged to tradesmen. The usage density of pitched tents and number of motor vehicles exceeded capacity and caused damage to the festival area. The average number of people per fountain and restroom (toilet) was recorded as 150 and 600 (1600 in the last day of festival), respectively. The average amount of garbage per person was calculated as 1.053 kg/day. Therefore, because of insufficient facilities and unplanned usage of the festival area, damage to the festival area was observed.
