    A Study on the Evaluation of the Socioeconomic Effects of Sugar Factories: A Case of Kastamonu
    (Çanakkale Onsekiz Mart Üniversitesi, 2021-10-28) Erenoğlu, Oya; Çimenderoğlu, Seda
    Since the first periods of the Republic, great importance has been attached to the industry in Turkey. One of the most important of these is sugar factories. The sugar adventure, which started with the first opened Uşak and Alpullu Sugar Factory, continued with the Kastamonu Sugar Factory opened in 1963. In this study, it was aimed to examine the socioeconomic effects of sugar beet agriculture and sugar production on Kastamonu. For this purpose, the survey method, one of the quantitative research methods, was used in addition to the field studies carried out in the factory and district centers (Center, Devrekani, Tosya, Taşköprü and Seydiler). With the questionnaire applied to 127 randomly selected farmers, it was aimed to measure the parameters such as the path followed by the local farmer in sugar beet production, the problems experienced, earnings, sowing and harvesting. Within the framework of the meeting held with the factory representative, information was provided about the works at the factory, privatization and the general situation of the farmers interested in sugar beet farming. According to the findings, sugar production in Kastamonu province is important in terms of creating a livelihood for the farmer and employment. In addition, the migration of the young population negatively affects the number of farmers in the region. The increase in fixed costs in production affects the farmer negatively. In particular, the regulation of input costs can be suggested as the main factor that will positively affect the yield in sugar beet.

    Accuracy Assessment of Low Cost UAV Based City Modelling for Urban Planning
    (Univ Osijek, Tech Fac, 2018) Erenoğlu, Ramazan Cüneyt; Erenoğlu, Oya; Arslan, Niyazi
    This paper presents an Unmanned Aerial Vehicles (UAV) based 3D city modelling approach to be used in managing and planning urban areas. While the urban growth is rapidly increasing in many places of the world, the conventional techniques do not respond to the changing environment simultaneously. For effective planning, high-resolution remote sensing is a tool for the production of 3D digital city models. In this study, it is aimed at designing the remote sensing by UAV through urban terrain. Using all the information produced from UAV imagery, high-accurate 3D city models are obtained. The analysis of XYZ data of the derived from 3D model using UAV photogrammetry revealed similar products as the terrestrial surveys which are commonly used for the last development plans and city maps. The experimental results show the effectiveness of the UAV-based 3D city modelling. The assessed accuracy of the UAV photogrammetry proved that urban planners can use it as the main tool of data collection for boundary mapping, changes monitoring and topographical surveying instead of GPS/GNSS surveying.

    Age and petrology of Eocene-Oligocene calc-alkaline volcanism in Biga Peninsula (NW Turkey): Implications for magma origin and geodynamic evolution
    (Pergamon-Elsevier Science Ltd, 2022) Erenoğlu, Oya; Bozcu, Mustafa; Billor, M. Zeki
    In NW Anatolia, Eocene-Oligocene post-collisional volcanism is represented by K-rich volcanic rocks, including high K calc-alkaline products. Magmatic rocks in the Dededag area (Biga Peninsula, NW Turkey) can be classified into 6 different groups with lithostratigraphic and chronostratigraphic data using 40Ar/39Ar methods (Eoceneearly Oligocene, 42.08 +/- 0.09 to 29.02 +/- 0.29 Ma). From the Eocene period, there are calc-alkaline Laledag granodiorite, Beycayir volcanics with andesite and dacite composition, and also Kizildam volcanics with alkaline and basic character (basaltic trachyandesite, trachybasalt). Furthermore, in the Oligocene period, calc-alkaline volcanism started with Dededag volcanics with dacite and rhyolite intermediate-acidic composition, continued with Kircalar volcanics consisting of basalt and basaltic andesite, and Harmancik volcanics ranging from basalt to rhyolite. The calc-alkaline camyayla pluton with quartz monzonite composition intruded into Oligocene Dededag and Harmancik volcanics in the region. Alkaline lavas in the region are classified as high-K and shoshonitic, and calc-alkaline lavas are medium-high-K. On N-type mid-ocean ridge basalt and chondritenormalized trace element diagrams, enrichment was observed for all volcanic units with regard to large ion lithophile elements and light rare earth elements. High field strength elements and heavy rare earth elements were depleted in all volcanic units. These compositions reveal the participation of a mantle source that was enriched by subduction components. Using geochemical data, all the volcanic rocks differentiated as a result of magma mixing/replenishment and contamination/assimilation processes. Consequently, the source of volcanism is thought to derive from the compressional regime associated with collision during the Eocene-Oligocene, and from a previously-enriched lithospheric mantle source with subsequent effects of the extensional regime.

    An UAS-assisted multi-sensor approach for 3D modeling and reconstruction of cultural heritage site
    (Elsevier France-Editions Scientifiques Medicales Elsevier, 2017) Erenoğlu, Ramazan Cüneyt; Akçay, Özgün; Erenoğlu, Oya
    Unmanned Aerial System (UAS) has been widely used to produce highly-precise orthomosaics, Digital Surface Models (DSMs), Digital Terrain Models (DTMs) and 3D models in many applications. UAS is also utilized to document cultural heritage sites using low-cost photogrammetric approach. Particularly, possibility of multi-sensor acquisition provides substantial information about both geometric features and material classification. In this study, a novel methodology using multi-sensor data acquisition is proposed in order to extract and to distinguish material features from UAS-based photogrammetry for the cultural heritages. Sensors which are able to collect visible, thermal and infrared radiations of the electromagnetic spectrum were employed to produce 3D model information of Assus Ancient Theater located in Behramkale Village, Canakkale, Turkey. The results showed that the accuracies of the 3D models were obtained as +/- 2-3 cm, +/- 10-15 cm and +/- 5-7 cm for the digital, thermal and multi-spectral camera systems, respectively. Beside the given high-accurate geometric model, the classification outcomes as a result of the spectral analysis revealed material features in an affordable and efficient way.

    An Under?Recognised Geoarchaeological Heritage Asset in Turkey: Dana Island, Mersin
    (Springer, 2021) Erginal, Ahmet Evren; Öniz, Hakan; Erenoğlu, Oya; Sarıaltun, Savaş
    Carbonate eolianites on Turkey’s 8333-km long coastline are extremely rare occurrences. Following pioneering studies at Bozcaada Island and Şile on the Aegean and Black Sea coasts, respectively, a new eolian geosite was recently found on Dana Island, an archaeological conservation area on the Mediterranean coast of Turkey. The eolianite, which was probably formed in a warm interglacial phase during Late Quaternary, is biogenic calcarenite in composition and contains a thick paleosol and well-preserved rhizoliths as root cast structures. As well as being a geological inheritance, the fact that eolianites are interbedded with very rare hard carbonate-cemented slope debris (colluvium) and both units are home to possibly the largest rock-cut ancient shipyard in the Eastern Mediterranean makes the island a unique geoarchaeological example with immense potential. These geological and archaeological heritage elements on Dana Island are sufcient evidence to identify the eolianites as a geoarchaeological heritage.

    Application of spectral analysis to determine geothermal anomalies in the Tuzla region, NW Turkey
    (Springer Heidelberg, 2019) Erenoğlu, Ramazan Cüneyt; Arslan, Niyazi; Erenoğlu, Oya; Arslan, Enis
    We used remote sensing data from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite to identify the mineral properties and geothermal anomalies related to hot springs in the Tuzla area, including the fault system with NW-SE trend, which is located southwest of Canakkale, NW Turkey. In the study area, the lithological units of the Tuzla geothermal field and the surrounding area consist of Miocene volcanic (trachyandesite, trachyte, and ignimbrites) and Pliocene sedimentary (conglomerate, sandstone, and mudstone) rocks with siliceous, argillaceous, and ferrous alteration linked to the geothermal fluid. ASTER visible/near-infrared (VNIR), short-wave infrared (SWIR), and TIR bands were analyzed by different approaches in order to highlight hot springs in the study area. From these approaches, band ratios were constructed from ASTER VNIR, SWIR, and TIR bands for obtaining geological properties of the region. The geothermal areas were defined by the minimum noise fraction (MNF) and principal component analysis (PCA) methods that was extracted from 5 thermal infrared (TIR) bands as well. Land surface temperatures (LST) support the results from MNF and PCA that were estimated for 5 TIR bands using the inversion of Planck function method. Four days of data including daytime and nighttime satellite images from ASTER were used for the analysis. The used procedure displayed a good match with the ground reality based on field observations in the Tuzla Region.

    Biga Yarımadasında Jeodeğerler ve Jeoturizm Potansiyeli
    (TMMOB Jeoloji Muhendisleri Odasi, 2018) Çalık, Ayten; Kapan, Sevinç; Erenoğlu, Ramazan Cüneyt; Erenoğlu, Oya; Yaşar, Cumali; Ulugergerli, Emin Uğur
    It is summarized what needs to be done and to be able to utilise three structurally different geological formations within the Canakkale province as geo-parks or geovalue that can attract geologically important and interestingtosocieties. As examples, hot water springs of Tuzla geothermalarea, ancient granite columns of Kestanbolu-Yahya Cavusvillage and opal pit of Yenice village are taken as examples. It is also emphasized that besides the areas highlighted, all other possible areas have their own specific conditions and that ignoring these conditions may cause permanent damages to the area. Earth science museum are also important institutions that will contribute to the discovery and introduction of these fields. As a way of preserving areas that are both scientific and tourist attraction, we have also listed our views on the importance of opening up and exploring to public and the negativity of this activity. According to the first results, while the Tuzla Geothermal field could be used with a few simple arrangements but Kestanbol and Yahya Cavus villages could not be used for the purpose of geotourism with its current state of the fields.

    Co-seismic beachrock deformation of 8th century AD Earthquake in Middle Strand of North Anatolian Fault, Lake Iznik, NW Turkey
    (Elsevier, 2021) Erginal, Ahmet Evren; Erenoğlu, Ramazan Cüneyt; Yıldırım, Cengiz; Selim, H. Haluk; Kıyak, Nafiye Güneç; Erenoğlu, Oya; Ulugergerli, Emin
    A historical earthquake-related co-seismic deformation observed on beachrock beds along the southern shoreline of Lake Iznik is discussed as a new paleoseismic record for an 8th century AD earthquake in the Middle Strand of the North Anatolian Fault, NW Turkey. Electrical Resistivity Tomography (ERT) images beneath the beachrock surface allowed monitoring of the subsurface trace of a normal fault dipping north along a 100 m surface rupture. No strike-slip deformation exists along the rupture, suggesting that the deformation in the beachrock is connected with a secondary structure, and that the main surface rupture was under the lake waters. The deformed beds of the beachrock, dated using Optically Stimulated Luminescence (OSL) to 1.3 ± 0.15 ka, are overlain by an undeformed secondary deposition of beds dated to 1.2 ± 0.09 ka. This allows us to narrow down the time of the faulting and implying that it was most likely a result of the AD 715 earthquake.

    CORRECTION AND DENSIFICATION OF UAS-BASED PHOTOGRAMMETRIC THERMAL POINT CLOUD
    (Copernicus Gesellschaft Mbh, 2016) Akçay, Özgün; Erenoğlu, Ramazan Cüneyt; Erenoğlu, Oya
    Photogrammetric processing algorithms can suffer problems due to either the initial image quality (noise, low radiometric quality, shadows and so on) or to certain surface materials (shiny or textureless objects). This can result in noisy point clouds and/or difficulties in feature extraction. Specifically, dense point clouds which are generated with photogrammetric method using a lightweight thermal camera, are more noisy and sparse than the point clouds of high-resolution digital camera images. In this paper, new method which produces more reliable and dense thermal point cloud using the sparse thermal point cloud and high resolution digital point cloud was considered. Both thermal and digital images were obtained with UAS (Unmanned Aerial System) based lightweight Optris PI 450 and Canon EOS 605D camera images. Thermal and digital point clouds, and orthophotos were produced using photogrammetric methods. Problematic thermal point cloud was transformed to a high density thermal point cloud using image processing methods such as rasterizing, registering, interpolation and filling. The results showed that the obtained thermal point cloud - up to chosen processing parameters - was 87% more densify than the original point cloud. The second improvement was gained at the height accuracy of the thermal point cloud. New densified point cloud has more consistent elevation model while the original thermal point cloud shows serious deviations from the expected surface model.

    Dededağ çevresindeki (Beyçayır-Çanakkale) eosen, oligo-miyosen volkaniklerinin krono-stratigrafik konumu ve Biga Yarımadası'nda bölgesel volkanizma içindeki önemi
    (Çanakkale Onsekiz Mart Üniversitesi Fen Bilimleri Enstitüsü, 2014) Erenoğlu, Oya; Bozcu, Mustafa; Karacık, Zekiye
    Bu çalışmada, Biga Yarımadası'nda Lapseki ilçesi güneydoğusunda Dededağ ve çevresinde geniş alanlarda mostra veren farklı evrelerde oluşmuş magmatik kayaların volkano-stratigrafik konumunun ve petrolojik özelliklerinin aydınlatılması amaçlanmaktadır. Bölgede 40Ar/39Ar yöntemi kullanılarak elde edilen yaş verileri ile, 42 My'dan (Geç Eosen) 29 My'a (Erken Oligosen) kadar olan dönemdeki magmatik üniteler; litostratigrafik ve krono-stratigrafik olarak 6 farklı birime ayrılabilmektedir. Eosen döneminde ortaç karakterli, kalkalkalen Laledağ intrüzifi (granodiyorit) ve Beyçayır volkanitleri (andezit, dasit) ile alkalen ve bazik karakterli Kızıldam volkanitleri (bazaltik trakiandezit, trakibazalt) gelişmiştir. Oligosen döneminde ise asidik-ortaç, kalkalkali nitelikli dasit ve riyolit bileşimli Dededağ volkanitleri ile başlayan volkanizma, bazalt ve bazaltik andezit bileşimli Kırcalar volkanitleri ve bazalttan riyolite kadar değişen Harmancık volkanitleri ile devam etmiştir. Çamyayla plütonu bölgedeki Oligosen volkanitlerini keserek yerleşmiştir. Bölgedeki alkalen lavlar yüksek K'lu ve şoşonitik olarak sınıflanırken, kalkalkalen lavlar orta-yüksek K'ludurlar. N-tipi MORB ve kondrite göre normalize edilmiş iz element değişim diyagramlarında ise, tüm volkanik birimlerde, büyük iyon yarıçaplı litofil elementler (LILE) ve hafif nadir toprak elementler (LREE) bakımından zenginleşme, yüksek alan enerjili elementler (HFSE) ve ağır nadir toprak elementler (HREE) bakımından tüketilme görülmüştür. Bu durum yitim bileşeni ile zenginleşmiş, manto kaynak alanından türeyen lavlara benzerlik gösterir. Jeokimyasal veriler ile bölgedeki tüm volkanik kayaçların, fraksiyonel kristallenme, magma karışımı/tazelenmesi, kontaminasyon/asimilasyon süreçleri sonucunda farklılaştıkları anlaşılmaktadır. Sonuç olarak; çalışma alanında yüzeyleyen volkanik birimlerin Paleosen-Eosen döneminde kuzeyde Sakarya kıtası ve güneyde Anatolid-Torid kıtalarının çarpışmasını takip eden sıkışma ve gerilme rejimlerinin etkisi ile daha önceden yitim bileşeni ile zenginleşmiş litosferik manto kaynağından türemiş olabileceği düşünülmektedir.

    Effects of Geological and Petrographic Factors on Landslide Development in the North of Biga Peninsula, NW Turkey
    (2021) Erenoğlu, Oya
    The study includes landslide movements that occurred on Eocene and Middle-Upper Miocene terrestrial and marine sedimentary units in the Biga Peninsula. In this study, three active landslide areas in Ambaroba, Şevketiye and Adatepevillages located on the northern coastof the Biga Peninsula were investigated. Geological studies ofthe Ambaroba landslide show the integrity of the Bayramiç formation and the Şapcıvolcanics in this area were influentialin the Miocene period. The sandstones in the Bayramiç formation are not very well consolidated, and are yellow, dirty yellow and gray in color. The sliding surface units in the moving masses consist of unconsolidated, very large blocky, pebbly and loosely cemented pebbles. In the Şevketiye and Adatepe landslides, sliding movement occurred on sandstone and conglomerate units with yellowish brown colors in the Fıçıtepe formation. The sandstones in these landslide areas are massive and well cemented. Conglomerates are weaker than sandstones with a gray-beige colorand no consolidation. Precipitation data and Global Positioning System measurements of the landslide areas were evaluated together with the lithological properties of the rocks. Loose sandstones and pebbles in the entire landslide areas can easily move due to seasonal precipitation. This movement was mostly seen in the Şevketiye landslide area and then in the Adatepe and Ambaroba areas, respectively. Although their effectiveness has decreased, movements will continue as the lithological features will not change in these areas. As a result, the measures specified in this study should be considered in order to eliminate the destructive effects of landslides.

    (Cem GAZİOĞLU, 2021) Erenoğlu, Oya
    The study includes landslide movements that take place on Eocene and Middle-Upper Miocene aged the terrestrial and marine sedimentary rock units on the Canakkale basin in the Biga Peninsula. In this study, the active Ambaroba Landslide, Şevketiye and Adatepe Landslides located on the northern coasts of Biga Peninsula were investigated.The geological studies in the Ambaroba landslide have shown the integrity of the Bayramiç formation and the Şapcı volcanics in this area have shown their influence in the Miocene period.The sandstones in the Bayramiç formation are not very well paste and are yellow, dirty yellow and gray in color.The sliding surface units in the moving masses consist of non-hardening, very large blocky, pebbly and loose cement-bonded pebbles. In the Şevketiye and Adatepe Landslides, a sliding movement has occurred on the sandstone and conglomerate units with yellowish brown colors in the Fıçıtepe formation. The sandstones in these landslide areas are massive and well cemented. Conglomerates are weaker than sandstones and are fond of a gray-beige color that does not harden. Precipitation data and GPS measurements of the landslide areas were evaluated together with the lithological properties of the rocks.Loose sandstones and pebbles in the entire landslide areas studied can easily move due to seasonal precipitation.This movement was mostly seen in the Şevketiye landslide area and then in the Adatepe and Ambaroba areas, respectively. Although their effectiveness has decreased, the movements will continue, as the lithological features will not change in these areas. As a result, the measures specified in this study should be taken into account in order to eliminate the destructive effects of landslides.

    Geological Features and Lithostratigraphy of Eocene-Oligocene Magmatic Rocks in the Dededağ Area-Biga Peninsula, NW Turkey
    (2021) Erenoğlu, Oya; Bozcu, Mustafa
    In NW Anatolia, Eocene-Oligocene post-collisional magmatism continued over long intervals. In this study, the aim is to reveal the lithostratigraphic position and geochemical characteristics of volcanic rocks outcropping southeast of Lapseki (Çanakkale) in NW Anatolia. The magmatic rocks that comprise the topic of this study can be classified lithostratigraphically into 6 different units in the region. In the Eocene period, there are calc-alkaline Laledağ granodiorite and Beyçayır volcanic rocks with andesite and dacite composition and intermediate character, and also Kızıldam volcanic rocks with alkaline and basic character (basaltic trachyandesite, trachybasalt). Furthermore, in the Oligocene period, calc-alkaline volcanism starting with Dededağ volcanics, which have dacite and rhyolite composition and acidic-intermediate character, continued with the Kırcalar volcanics consisting of basalt and basaltic andesite, and the Harmancık volcanics ranging from basalt to rhyolite. The Çamyayla Pluton intruded into Oligocene volcanic rocks in the region. In this study, the geochemical data proved that magmatic units have alkaline and calc-alkaline character in the Eocene-Oligocene period. Alkaline lavas in the region are classified as high K and shoshonitic and calc-alkaline lavas are medium-high-K.

    Mineralogical Properties and Geochronology of the Can Stone Tuff ( Biga Peninsula, NW Turkey)
    (Tmmob Jeoloji Muhendisleri Odasi, 2017) Erenoğlu, Oya
    Can stone is composed of rhyolitic tuffs, which are the pyroclastic products of the Oligocene volcanics of the Biga Peninsula, which have widespread outcrops around Can-Etili. In this study, the petrographic and mineralogical (XRD-SEM / EDX) evaluations of Can stone tuffs are carried out. Furthermore, geochronological dating is performed to determine the chronostratigraphic position in the widespread volcanism of the area. The Can stone tuff, which is determined to be of late Oligocene age, shows light yellowish, creamy and reddish -brownish different motifs developed by ferrious oxidation after hydrothermal alteration. According to the results of the XRD and SEM / EDX analyzes of Can stones; quartz, sanidine, albite, pyrite, kaolinite, alunite and rarely biotite and amphibole minerals are detected. The pyrite minerals, which are rarely euhedral and mostly composed of crystals packed in frambolites, form different patterns on these tuffs. Owing to these motifs, Can stones have been interested and used for covering stone and / or for decorative purposes in the construction sector for many years.

    New record of calcarenite in Hatay, Turkey: an evidence of the Late Pleistocene Eastern Mediterranean–Red Sea connection
    (Springer Science and Business Media Deutschland GmbH, 2021) Erginal, Ahmet Evren; Polymeris, Georgios S.; Erenoğlu, Oya; Giannoulatou, Valeria; Meriç, Engin; Karataş, Atilla; Şahiner, Eren; Selim, H. Haluk
    This study discusses the composition and age of calcarenite deposits and aeolianite overlying the upper Cretaceous ophiolites in the eastern Mediterranean north of the Asi River Delta. They record the Mediterranean–Red Sea water connection in the Late Pleistocene. Petrographic analysis and microfossil determination showed that these deposits are classified as micritic calcarenite and biocalcarenite, indicating deposition in a high-energy shoal environment and carbonate aeolianite with abundant rhizoliths as residuals of rootlet calcification. The invasive species of Amphistegina lobifera Larsen and Peneroplis pertusus (Forskal) found in the calcarenite and aeolianite make it clear that the Indo-Pacific Ocean waters reached the Levantine Sea basin during the periods MIS 5e and/or MIS 5c by following a palaeo-channel along the Gulf of Suez.

    Raised braided stream gravels on Mount Keldağ, Hatay (Eastern Mediterranean coast, Turkey): implications of transformation to beachrock and ensuing tectonic uplift
    (Springer Science and Business Media B.V., 2019) Erginal, Ahmet Evren; Polymeris, Georgios S.; Karataş, Atilla; Giannoulatou, Valeria; Şahiner, Eren; Meriç, Niyazi; Erenoğlu, Oya
    On the seaward northwest slopes of Mount Keldağ, Hatay, the combination of an unconformably overlapping sequence of cemented gravels on a wave-cut platform, and a raised notch and irregular pits left by grazing molluscs on the walls of this notch, carved in an NE-trending high-angle fault plane, retain the record of raised braided stream gravels transformed into beachrock. From the OSL ages, this study reveals that deposition of this sequence occurred between 232.30 ± 31.62 and 214.01 ± 27.42 ka during the penultimate interglacial. The four distinct facies identified are massive matrix-supported conglomerate, massive to crudely stratified gravel, cross-stratified gravel, and clast-supported open-work gravel. Extending to the paleo-coastline during the MIS7 highstand, this sequence was cemented by carbonate and iron-oxide cements and records an uplift of around 0.1 mm/year up to the present. © 2019, Springer Nature Switzerland AG.

    Şeker Fabrikalarının Sosyoekonomik Etkilerinin Değerlendirilmesine Yönelik Bir Çalışma: Kastamonu Örneği
    (Çanakkale Onsekiz Mart Üniversitesi, 2021) Çimenderoğlu, Seda; Erenoğlu, Oya
    Cumhuriyetin ilk dönemlerinden itibaren Türkiye’de sanayiye büyük önem verilmiştir. Bunların en önemlilerinden biri de şeker fabrikalarıdır. İlk açılan Uşak ve Alpullu Şeker Fabrikası ile başlayan şeker serüveni 1963 tarihinde açılan Kastamonu Şeker Fabrikası ile devam etmiştir. Bu çalışmada, şeker pancarı tarımı ile şeker üretiminin Kastamonu iline olan sosyoekonomik etkilerinin incelenmesi amaçlanmıştır. Bu amaçla araştırmada, fabrika ve ilçe merkezlerinde (Merkez, Devrekâni, Tosya, Taşköprü ve Seydiler) yürütülen arazi çalışmaları yanında nicel araştırma yöntemlerinden anket metodu kullanılmıştır. Rasgele seçilen 127 çiftçiye uygulanan anket ile yöre çiftçisinin şeker pancarı üretiminde izlediği yol, yaşanan sıkıntılar, kazancı, ekim ve hasat gibi parametrelerin ölçülmesi hedeflenmiştir. Fabrika yetkilisi ile gerçekleştirilen görüşme çerçevesinde fabrikadaki çalışmalar, özelleştirme ve şeker pancarı tarımı ile ilgilenen çiftçilerin genel durumu hakkında bilgi sağlanmıştır. Elde edilen bulgulara göre Kastamonu ilindeki şeker üretimi çiftçiye geçim kaynağı oluşturması ve istihdam bakımından önemlidir. Ayrıca genç nüfusun göçü bölgedeki çiftçi sayısını olumsuz etkilemektedir. Üretimdeki sabit giderlerin artması çiftçiyi olumsuz yönde etkilemektedir. Özellikle girdi maliyetlerinin düzenlenmesi şeker pancarında verimi olumlu yönde etkileyecek ana etken olarak önerilebilir.
