    The Ecosystem Services and Green Infrastructure: A Systematic Review and the Gap of Economic Valuation
    (MDPI, 2022) Ersoy Mirici, Merve
    This study was conducted to determine the trends at the intersection of studies made on green infrastructure and ecosystem services, which have frequently become preferred in establishing urban-green space relationships in global research. Green-related concepts have frequently been used from past to present in order to neutralise the increasing pressures on urban dynamics resulting from rapid urbanisation. Green corridor, green belt, green structure, and green finger/hand concepts have been used to provide recreational opportunities, protect nature, and keep urban sprawl under control. For the last decade, however, in addition to the traditional green concepts, green infrastructure (GI) and ecosystem services (ES) have been preferred in contemporary urban planning, as they enable the integration of the ecological concerns of the landscape and the socio-political perspective. The aim of this study is to detect the trends of the green infrastructure and ecosystem services association, and to reveal these trends in the common area with the bibliometric mapping method. The economic concept and its analysing use at the intersection of green infrastructure and ecosystem services were explored with VOSviewer using the Scopus(R) database. Furthermore, the number of documents, which initially began with around 39,719 studies, was reduced by filtering through systematic reviews, to only three documents that met the economic valuation criteria. In this way, a lack of economic analyses, creating a serious research gap within the framework of green infrastructure and ecosystem services, was quantitatively determined.

    EFFECT OF LAND USE AND TOPOGRAPHIC FACTORS ON SOIL ORGANIC CARBON CONTENT AND MAPPING OF ORGANIC CARBON DISTRIBUTION USING REGRESSION KRIGING METHOD
    (North Univ Baia Mare, 2020) Demir, Yasin; Ersoy Mirici, Merve
    The study investigates the effects of land use type and topographic properties on soil organic carbon (SOC) in a catchment with a high annual soil loss due to erosion. In addition, the SOC content was determined by modeling the SOC distribution map using the regression-kriging (RK) method. Within this context, the effects of forest land (FL), degraded forest (DF), barren area (BA) and agricultural areas (AA) and different topographic factors (elevation, slope, aspect) on SOC were examined. The catchment had an area of 10675 ha and 429 soil samples were collected to determine the SOC contents of the soils. The results revealed that land use type had a significant effect on SOC and FL had the highest SOC content. However, there was no relationship between elevation and SOC. On the other hand, the SOC content decreased inversely proportional to the slope of the lands The soil loss due to erosion is considered an important factor causing the decrease. The aspect of the land was also determined to have an important effect on the SOC content. The increase was mostly attributed to relatively less sunlight received by the northern slopes in Turkey. The lands on the northern slopes had the highest SOC content, while the lowest SOC content was determined in the southwest areas. The SOC contents depending on the land use type were close to each other according to the RK and normal regression methods.

    GEOGRAPHIC INFORMATION SYSTEM AIDED LANDSCAPE INVENTORY AND WATERSHED ANALYSIS IN ULUDAG NATIONAL PARK, TURKEY
    (Parlar Scientific Publications (P S P), 2019) Ersoy Mirici, Merve; Cabuk, Saye Nihan; Cabuk, Alper
    Protected areas are the geographic areas defined and managed by laws to ensure long-term conservation of ecosystem services and cultural values with nature, and it is of great importance for future generations to access pristine natural resources. Uludag National Park has rich ecosystem efficiency in terms of plant and animal biodiversity, endemic plant species, carbon storage capacity, snow cover and water potential. For this reason, protected area boundary and size are important for the holistic protection of water and natural resources. In this study, the landscape inventory of Uludag National Park was determined by Geographical Information Systems (GIS) and the potential watershed boundaries were determined by ArcHydro Watershed analysis. As a result of the study, the difference between the actual and potential basin areas is estimated to be approximately 11.20 ha. The protected area serves a qualified mission to ensure that natural resources are sustained for the future generations in a fair and protected manner when the basin borders are considered as an integrated boundary that feeds the hydrological cycle.

    LAND USE/COVER CHANGE MODELLING IN A MEDITERRANEAN RURAL LANDSCAPE USING MULTI-LAYER PERCEPTRON AND MARKOV CHAIN (MLP-MC)
    (Corvinus Univ Budapest, 2018) Ersoy Mirici, Merve; Berberoglu, S.; Akın Tanrıöver, Anıl; Satir, O.
    Mediterranean land use and land cover (LULC) have a very dynamic structure as a result of continuous transformation process due to anthropogenic effects and environmental gradients. LULC dynamics are important indicator of environmental condition in temporal and spatial scales. The aim of this paper was to simulate the future LULC of a Mediterranean type watershed located at the Eastern Mediterranean Region of Turkey by incorporating multi-layer perceptron (MLP), artificial neural network (ANN) and Markov chain (MC) approaches. Landsat TM/OLI images in 1990, 2003 and 2014 over the study area were classified using hybrid classification approach. The Kappa statistics of the hybrid classification that combines K-means, decision tree and object based classification method for these three images were 0.81, 0.85 and 0.87 respectively. The LULC map of 2014 was simulated using LULC maps of 1990 and 2003 for calibration and validation. The simulation results were compared with the actual 2014 LULC map to assess the accuracy of the simulation, and the rate of overlap was found as 89%. LULC map of 2025 was estimated using LULC maps of 2003 and 2014. These results indicated that, the area of bareground will reduce 13.31% whereas the rate of forest and agricultural area will increase 8.70% and 6.51% respectively.

    LANDSCAPE INVENTORY AND CHARACTER ANALYSIS: A CASE STUDY FROM URLA, CESME, KARABURUN DISTRICT, TURKEY
    (Parlar Scientific Publications (P S P), 2019) Alparslan, Ceren; Ersoy Mirici, Merve; Saricam, Sibel; Cabuk, Alper
    In this study, natural, socio-cultural and visual landscape characteristics of the study area were determined by using Geographical Information Systems (GIS) technologies in Izmir-Cesme and Karaburun district located in the north of IzmirCesme highway and landscape inventory and character analysis of the area were conducted. In this scope of the study, the natural and socio-cultural components of the landscape were examined in a planning approach that is sensitive to ecology, environment and natural disasters, in accordance with the conservation-use balance. In the first phase of the study, natural and socio-cultural indicators in the landscape inventory were compiled on the GIS base. In the second phase, the landscape function analysis, which reflects the natural functions of the study area for landscape character analysis, was produced through visual-aesthetic-perceptual landscape quality, water permeability, surface runoff potential, soil erosion risk and habitat value components. Finally, landscape character type maps specific to study area were produced using landuse/ landcover, elevation, slope, forest stand map, great soil groups and rock permeability components. Cluster analysis was performed so that landscape character types can be reduced and interpreted numerically. Suggestions for landscape management strategies were developed by presenting the landscape inventory function and character types of Urla, Cesme and Karaburun districts in the direction of the findings obtained.

    Monitoring the Mediterranean type forests and land-use/cover changes using appropriate landscape metrics and hybrid classification approach in Eastern Mediterranean of Turkey
    (Springer, 2020) Ersoy Mirici, Merve; Satir, Onur; Berberoglu, Suha
    Monitoring the Land-Use/Cover Change (LUCC) is an important tool to evaluate the reasons for environmental changes in ecologically sensitive landscapes like natural forestlands. Rural landscapes are of vital importance for ecosystem productivity, ecosystem services, and biological diversity to continue sustainably. The purpose of this paper was to detect LUCC and its effects on landscape ecology through landscape metrics in the Eastern Mediterranean of Turkey. In this study, a hybrid classification approach was used to classify the Land-Use/Cover (LUC) and detailed forest tree diversity considering topography, plant density, and satellite waveband reflectance values. To this extent, detailed LUC classification, LUCC analyses from 2003 to 2014, habitat quality differences by generating landscape metrics in two levels are called landscape and class-level metrics were carried out in the study area. Habitat quality evaluation on forest formation scale using a hybrid classification approach provided a great advantage and made it possible to examine the landscape metrics of the plant types within the scope of temporal change. The study method was implemented in seven stages including: (1) classification of forest-no forestlands with the K-Means algorithm, (2) creating a data set of reflected signals over stand types, (3) determining the rules and thresholds of decision tree algorithm, (4) object-based classification of agricultural, rocky, and settlement areas, (5) obtaining the land-cover maps for 2003 and 2014, (6) post-classification change detection analyses, and (7) assessing the habitat quality via landscape metrics. The results indicated that forest areas increased by 10.73%, while bare soil decreased by 17.70% in 12 years. The habitat quality increased in the same period in the study area according to the results of class area, mean shape index, mean patch size index, edge density, patch number, and Shannon's diversity index values.

    Spatial distribution of gokcay basin forest biomass and carbon storage service
    (Scibulcom Ltd., 2020) Ersoy Mirici, Merve; Tulek, B.
    Landscapes have a structure that contains many functions and ecosystem services with their natural and cultural components. Vegetation especially in natural landscapes stands out not only visually, but also in terms of ecosystem services. It is known that carbon dioxide and carbon monoxide gases are among the greenhouse gases that have the highest share in global warming. Forest areas have climate protection functions by protecting settlements, agricultural areas and recreational facilities from the harmful effects of cold weather and wind, extreme weather changes and improving the regional climate. In this study, the focus is on the carbon storage service, which is evaluated in the category of regulatory services under ecosystem services. For the determination of forest biomass carbon storage capacity of Gokcay Basin, located in Turkey’s western Black Sea region, biomass estimation method calculated at the unit area level is used within the scope of LULUCF (Land use land use change and forestry) applications. In the method: (i) map of forest stand types; (ii) acreage of forest stand types; (iii) tree volume value; (iv) biomass expansion factor, wood density, root/shoot rate coefficients, and (v) percent tree cover map produced with remote sensing data are used. © 2020, Scibulcom Ltd..
