    Determining suitable ecotourism areas in protected watershed area through visibility analysis
    (Scibulcom Ltd, 2019) Demir, Sara
    The rapid population growth, technological improvement and the expansion the boundary of urban have affected the natural and cultural landscape values of rural areas negatively. This causes to consumption unawares natural and cultural values of landscape. Mary Valley protected watershed area, located in Macka, Trabzon, has one of the important national park, cultural heritage points, historical trails, river falls, natural forest views, wildlife and endemic plants was selected as a study area. Its landscape values have been damaged because of lack of administrative structure. This study aims to explore the natural and cultural landscape values and highlight the importance of cultural, historical and natural viewpoints of the Mary Valley. To achieve this goal, the natural and historical landscape data are collected and multi-criteria decision making methods, is employed on the basis of the data derived from the surveys and interviews with local and experts and then all data overlayed through visibility analysis process in GIS. Finally, 'very high-high and medium visibility areas' are offered as suitable ecotourism areas for ecotourism activities, which has no negative effects to natural and cultural areas. The findings can set guidance for sustainable for protected national and cultural values of watershed area in Turkey.

    An ecological restoration assessment integrating multi-criteria decision analysis with landscape sensitivity analysis for a hydroelectric power plant project: the Tokat-Niksar case
    (Springer Science and Business Media Deutschland GmbH, 2021) Demir, Sara; Demirel, Ö.; Okatan, A.
    Due to Turkey’s reliance on imported electricity, it has been using hydroelectric power plants (HPPs) to cover some of its electrical energy needs since 2011. However, HPP projects, which do not take landscape sensitivity into account, cause the ecological integrity of the basins and the ecosystem structure to deteriorate. This study presents the Tokat-Niksar HPP project field example in Turkey’s Central Black Sea region with its steep slopes, rich forest and creek vegetation, protected endemic plants and wildlife, cultural heritage dating back to 3000 BC agricultural activities, and long-established local culture. The study, in fact, aims to develop a landscape restoration plan that considers the sensitivity of landscapes in the HPP project area. For this purpose, a landscape sensitivity analysis consisting of water, habitat, visibility, erosion functions, and multi-criteria decision analysis (MCDA) determining priority of functions conducted with experts were performed. According to the results, the water function was found to have the highest, and the visibility the lowest priority in the ranking. Consequently, 1st, 2nd, 3rd, and 4th-degree sensitive areas with very high, high, and moderate landscape sensitivity were determined by weighted sum function by considering the priority of each landscape function, and accordingly, a five-stage landscape restoration model was developed including soil protection, areas to be protected, erosion control, vegetation screening, and creek reclamation. This study presents a framework for sustainable landscape restoration solutions in the town by combining landscape sensitivity analysis via MCDA.

    ENERGY EFFICIENT LANDSCAPE DESIGN PROPOSALS IN TRABZON CITY CENTER
    (Parlar Scientific Publications (P S P), 2018) Demir, Sara; Koc, Seren
    The population growth, technological development, unsustainable consumption, disasters and climate changes in urban cities cause to destroy the natural and cultural values, decay the ecological integrity and changes landscape of urban. The increasing trend of urban has been recognized in the international scale and takes into consider the improvement of sustainable energy efficient in recent years. Urban open spaces have important role on human life as a social welfare and on ecological integrity of urban life. Lack of green infrastructure system and unsustainable intensively impermeable construction affected negatively the quality of urban. Therefore, one of the development countries, Turkey, is under pressure because of rapid and unplanned urban growth. Trabzon is one of the big cities of Turkey and it has rapidly grown after declaring as a metropolitan municipality since 2012. Thus, open green areas in urban have turned to intensively construction area and caused to diminish the open spaces. As a result, Trabzon city center needs to increase the green open spaces and control the heat island due to impermeable surfaces. In this context, the aim of this study is to offer sustainable energy efficient methods by designing green infrastructure with water conservation to reduce urban heat effects caused by climate change. To reach our aim, it was developed the street design proposal in Kahramanmaras street of Trabzon city center to create both green open green spaces and collect the rainwater for social, ecological and economic urban life. For this energy efficient design in Kahramanmaras Boulevard, rainwater was collected by green systems, storage and filtering. The green rainwater collector with filtering was best effective way to protect water and increase the healthy green areas by decreasing the intensive vertical and horizontal impermeable surfaces for this study. These street design proposals can set a good example for the other cities under pressure of urban growth and improve social and economic life quality of citizen and ecological integrity of urban landscape by providing urban and environmental balance.

    LANDSCAPE DYNAMICS CHANGES OF THE PROTECTED MARY VALLEY, TURKEY
    (Corvinus Univ Budapest, 2019) Demir, Sara
    This paper presents the case of Mary Valley's protected catchment, which is located in the northeast Black Sea Region of Turkey, and was declared a national park in 1987. The study area has sensitive ecosystems, with rare and endangered endemic plants. Nevertheless, current unsustainable economic activities, uncontrolled tourism and population migration have adversely affected its sensitive ecological integrity. This research aims to monitor and analyze the landscape dynamics changes of land use-land cover and landscape structure by change detection and landscape metrics in 1987, 1998, 2009 and 2016. The relationship between LULC and habitat changes linked to those of endemic plants were aimed to be determined. The findings indicated that forest areas with the highest loss transformed into grassland, shrubland and bare land areas, while bare land experienced the highest gain. However, forest area has the highest and bare land has the lowest habitat function. Additionally, endemic plant habitats have an inverse relationship with the habitat value of forest and bare land areas and a direct relationship with shrublands. These unsuitable changes can adversely pressure the sensitive landscape dynamics of Mary Valley protected area. Thus, landscape dynamics and their changes should be monitored to protect and manage for the sustainable development of Mary Valley resources.

    The prioritization of natural-historical based ecotourism strategies with multiple-criteria decision analysis in ancient UNESCO city: Iznik-Bursa case
    (Taylor & Francis Inc, 2019) Demir, Sara; Sayan Atanur, Gül
    Ecotourism contains the integration from ecological integrity and economic benefits to environmental and historically sensitive areas. One of the major keys of ecotourism-planning strategies is to ensure the sustainability of unique natural and cultural resources by a balance strategy between protection and use. It causes both the increase of the ecotourism awareness of local people and visitors and the decrease of the environmental problems and visitor pressures on the landscape resources of potential ecotourism areas. For this reason, the study presents the example of Iznik which is an ancient Greek, Roman, Byzantine, and Ottoman city of Nicaea with its lake, historical walls and gates, churches and early-period mosques, ceramic tiles, and agricultural activities on the southeast of Marmara Region, Turkey. It has been declared to have a different protected area status. However, the number of unsuitable management and uncontrolled economic activities has caused damage to sensitive landscape values. The aim of this research is to define ecotourism criteria for Iznik and it offers ecotourism strategies for the sustainability of sensitive landscape areas. Fieldwork, field observation, interviews and survey study with integrated multiple-criteria decision analysis and strengths-weakness-opportunities-threats (SWOT) analysis conducted with locals, tourists and experts were performed for this purpose. According to the results, among the 4 main and 15 sub-criteria of ecotourism to be in UNESCO Tentative List, the opportunity for ecotourism-planning strategy was found as the highest priority ranking. This research proposes a framework by using a priority-ranking method for the development of ecotourism strategies in the town.

    The user satisfaction of urban park: Case of trabzon eyof memorial park
    (Parlar Scientific Publications, 2020) Bayramoglu, E.; Demir, Sara
    Urban parks are open green spaces that can provide the physical and spiritual needs of the urban occupants in their leisure time and also improve the quality of urban life. These parks offer intense activity opportunities for the city users because of their location in city center and its immediate surroundings. The diversity of activities, usage density and accessibility to the area are the main important issues for the user satisfictation of urban parks. In this context, the aim of this study is to determine the user satisfaction of Eyof Memorial Park in Trabzon.To reach of this aim, it was applied two main stages. In the 1st stage; a questionnaire consisting of 15 questions in total was conducted in order to determine the sociodemographic situation, usage status and time of the user group. In the 2st stage; the factors effects on the users satisfaction and dissatisfaction were evaluated by 11 experts on the Likert attitude scale. As a result, 22 satisfaction and 14 dissatisfaction criteria were determined. Accordingly, the criteria of satisfaction and dissatisfaction are grouped under 3 main factors (Personal criteria (Fl), Social criteria (F2), natural and environmental impacts (F3). Consequently, it was determined 79.46% satisfaction rate and 47.83% dissatisfaction rate with 3,973 average value for Trabzon Eyof Memorial Park. The findings and methodology of this study may be an example for development of user satisfaction of urban parks in the developing countries. © 2020 Parlar Scientific Publications.
