Öğe Reducing Food Loss and Waste in the Fish Value Chain: A Study on Environmental Efficiency in Türkiye(Wiley, 2025) Türkten, Hatice; Yıldırım, Çağatay; Yüceer, Sema EzgiFood loss and waste (FLW) significantly threaten food security, economic stability, and environmental sustainability, particularly within the fish value chain due to the high perishability of seafood. This study examines FLW in Türkiye's fish value chain, focusing on the Çeşme district, to quantify waste levels and evaluate environmental efficiency. Using firm-level data collected from commercial fisheries, aquaculture enterprises, and processing facilities, we analyze the socio-economic factors influencing FLW and assess the impact of inefficiencies in cold chain management, logistics, and processing operations. The findings indicate that FLW occurs at multiple supply chain stages, with the highest losses observed during processing and retail. Environmental efficiency analysis reveals that improving management practices and adopting advanced cold storage technologies can significantly reduce waste and greenhouse gas emissions. Additionally, it is revealed that FLW rates reached 70.7% in small-scale fisheries, 53.6% in large-scale fisheries, and 63.6% in aquaculture. Environmental efficiency scores ranged from 0.448 to 0.603 across production types. Policy interventions, including stricter sustainability regulations, financial incentives for technological adoption, and consumer awareness campaigns, are recommended to mitigate FLW. This study contributes to the growing literature on sustainable fisheries management by providing localized insights into FLW reduction strategies. Enhancing technological infrastructure, optimizing transportation networks, and strengthening regulatory frameworks can minimize waste, improve resource efficiency, and promote sustainability within the fishery sector.Öğe Content Proposal for a Chatbot Module on Climate Change Mitigation in Sugar Beet Production(Springer India, 2025) Yakupoğlu, Murat; Everest, BengüSugar beet production is one of the significant agricultural activities contributing to climate change due to its high input costs and capital-intensive nature. This study examines the tendencies of sugar beet farmers regarding methods to mitigate climate change and combines these findings with a proposal for a digital solution. This research, conducted in Konya province, a leading sugar beet production center in Türkiye, evaluated farmers’ perceptions of climate change mitigation methods using a Likert scale and logistic regression analysis. The findings, categorized into five groups (water management, soil conservation, reduction of carbon emissions, pest control, and other practices), revealed that farmers prioritize practices that provide economic benefits. The logistic regression results showed that farmers’ willingness to receive climate change training was significantly associated with their frequency of visits to agricultural institutions (3.20 times more likely), engagement in livestock farming (0.14 times more likely), and their level of concern about climate change (6.17 times more likely). The primary importance of this study lies in its integration of the obtained quantitative findings with digital agricultural solutions. The research results provide a critical foundation for designing a personalized chatbot that can address the needs and tendencies of farmers. The chatbot to be developed should be designed as a communication platform that can approach farmers’ concerns with empathy, effectively convey institutional support mechanisms, and offer solutions focused on economic benefits.Öğe Sustainable site selection for a cooperative dairy factory in NW Türkiye(Global Network Environmental Science & Technology, 2025) Everest, Bengü; Everest, TimuçinThe world population is increasing, and agricultural products are strategically crucial for feeding the growing world population. In developed countries, cooperatives serve as an essential tool to ensure the sustainability of agricultural production and reduce costs. In Türkiye, cooperatives play a limited role in controlling the agricultural product market. There are many dairy cooperatives in Türkiye, but they are often ineffective in processing and marketing milk effectively. This study was conducted in Çanakkale, NW Türkiye. In this study, an approach was proposed to enable dairy cooperatives to select suitable sites for establishing a dairy factory. With this proposed approach, milk production quantity, population, land characteristics (land use capability classification (LUCC), and environmental conditions (solar energy potential) were used as main criteria. The Best Worst Method (BWM), a newly developed multi-criteria decision-making method (MCDM), was employed to determine the weights of the selected criteria. A geographical information system (GIS) was used to produce the final suitability map. Based on the BWM calculations, milk production quantity was identified as the most effective factor (46.55%), followed by population (25.86%), land use capability classification (17.24%), and photovoltaic potential (10.35%). The suitability analysis revealed that the Biga district was the most suitable location for establishing a dairy processing plant. The significance of the Biga district lies in its high milk production, large population, and well-established infrastructure that supports milk processing and marketing activities. The novel approach of this study is the integration of milk production, population, land use, and renewable energy potential through a Multi-Criteria Decision-Making (MCDM) method within a GIS environment, providing a guideline for the sustainable milk processing capacities of agricultural cooperatives. By considering photovoltaic potential and the utilization of marginal lands, the study emphasizes the importance of renewable energy and land conservation in dairy processing, thereby ensuring long-term environmental and economic benefits. Prioritizing sustainable and cooperative-oriented development contributes to Türkiye's efforts to strengthen its agricultural sector. The data produced by this study can be utilized by politicians, decision-makers, cooperative members, farmers, and other relevant stakeholders.Öğe RURAL WOMEN'S PARTICIPATION IN DAIRY FARMING ACTIVITIES IN THRACE REGION OF TÜRKİYE(Pakistan Agricultural Scientists Forum, 2025) Özsayın, DamlaThis study aims to define the tendency towards participation in dairy farming activities of rural women who live in Thrace region of Türkiye. The collection of data from 380 rural women was accomplished using the proportional sampling method. Between December 2023 and July 2024, the survey for this study was carried out. The study data was examined with the use of descriptive statistics, participation index score and multiple regression analysis. Current study's findings revealed that women had an average age of 39.3, the average education level was 8.9 years, the average family size was 3.3 people, the average dairy farming experience was 7.3 years, the average annual household income was €2660.2 and the average volume of dairy cattle was 25.6 head. Rural women were found to be most engaged in dairy farming activities during the feeding and watering stage while the least in the purchasing, processing and marketing stage according to the participation index score results. The results of multiple regression analysis indicated a statistical significant association between rural women's participation level in dairy farming activities and socio-economic characteristics. The findings indicated that middle-aged, more educated and more experienced women were more inclined to engage in these activities than other women. Consequently, the study findings are expected to contribute the economy of the study area, to the decision makers and agricultural policy makers interested in this subject, and to further emphasize rural women's importance in dairy farming activities.Öğe 15.

Ulusal Tarım Ekonomisi Kongresi, 6-8 Eylül 2023, Çanakkale, Bildiri Kitabı(Çanakkale Onsekiz Mart Üniversitesi, 2023) Tan, Sibel; Aktürk, Duygu; Semerci, Arif; Everest, Bengü; Niyaz Altınok, Özge Can; Kayalak, Selma; Yüceer, Sema Ezgi; Durmuş, Eylem; Tan, Sibel; Aktürk, Duygu; Semerci, Arif; Everest, Bengü; Niyaz Altınok, Özge Can; Kayalak, Selma; Yüceer, Sema Ezgi; Durmuş, Eylem[No Abstract Available]Öğe Analysis of ınput utilization efficiency in wheat production: the case of Turkey(Univ Fed Rural Pernambuco, Dept Administracao, 2024) Çelik, Ahmet Duran; Semerci, Arif; Sarıoğlu, TuğçeWheat production is an essential agricultural activity in the world and Turkey. In 2021, the world wheat production was realized as 771 million tons on 221 million hectares of land. Turkey had a share of 3.00% in the world's wheat production area, and 2.29% in the production amount. The most important condition for the competitiveness of enterprises in agricultural production is low production costs and efficient use of inputs. Unused input not only increases production costs but also reduces the competitiveness of the businesses. In this study, input use efficiency in wheat production was analyzed by means of the data obtained from 104 enterprises determined by the Simple Random Sampling Method. The average cultivation area of wheat production was 159.03 da, and the yield per unit area was determined as 555.00 kg/da. In the function of wheat production; the production elasticity coefficient of the fertilizer variable was found significant at a 1% probability level, and the agricultural pesticide at a 5% probability level. The sum of the coefficients of production elasticity (& sum;beta(i): 1.013) for the forecast function indicates increasing returns to scale. The highest marginal efficiency coefficient (2.34) in the equation was found as the seed variable. The research results revealed that none of the variables in wheat production were used at the economic optimum level.Öğe Determination of resource use efficiency in table tomato (Solanum lycopersicum) production: Çanakkale province-Turkey sample(Universidade Federal Rural de Pernambuco, 2024) Durmuş, Eylem; Semerci, ArifTurkey is one of the most prominent tomato producing countries in the world. Tomat oes are in fourth place in the ranking of countries in terms of production area and in third place in terms of quantity of production. According to data from the Food and Agriculture Organization of the United Nations for 2020, Turkey provides 3.60% of the tomato production area worldwide and 7.07% of its production. In this study, it has been aimed to determine the resource use effectiveness of the factors applied in table tomato production in Canakkale province, which is one of the most significant tomato production centers. The data used in the research have been obtained by applying a face-to-face survey from 99 agricultural enterprises identified by the Stratified Sampling Method. Determination coefficient of the estimation equation of table tomato production created with the help of Cobb-Douglas type function is 0.912 and this value has been found significant at a 1% significance level. In the study, the sum of elasticity coefficients of production factors included in the estimation equation prepared for tomato production has been calculated as 0.96. The calculated value indicates that in the production of table tomatoes, there seems to be a reduced return to the scale. The presence of autocorrelation of the equation has been tested by the “Durbin Watson Test”. The Durbin Watson test statistic has been found as 1.914, and there seems no autocorrelation between the variables. When the production elasticity coefficients belonging to the arguments, which are included in the equation, have been examined; machine tensile strength and fuel consumption quantity variables have been found to be negative marked. In the estimation equation, seedling number of 1%, machine traction and labor factors have been found to be significant at the level of probability of production elasticity coefficients of 10%. When we consider the marginal efficiency coefficients of inputs used in table tomato production, it is seen that pure fertilizer (13.08), labor force (9.59) and number of seedlings (4.84) factors were found to be used below the economic optimum level, and the amount of use of specified inputs per unit area need to be increased. The marginal coefficient of effectiveness of the agricultural pest control drug used in tomato production is less than 1, and it has been recommended to reduce the use of this input. Other variables included in the estimation equation such as marginal efficiency coefficients related to machine traction power and diesel quantity are negatively marked and these inputs are used in the irrational region in tomato production. The study has revealed that production factors are not used effectively in the production of table tomatoes, which negatively affect the producer's income.Öğe Drivers of Capia Pepper Farmers' Intentions and Behaviors on Pesticide Use in Turkey: A Structural Equation Model(Ankara Univ, Fac Agriculture, 2024) Günay, Tarık; Niyaz Altınok, Özge CanThe main actors responsible for pesticide use behavior are farmers. Still, factors are influencing the pesticide use behavior of farmers in the background. The theory of planned behavior is a widely used concept that explains farmers' pesticide use behavioral intention. However, previous studies show that behavior is not included in the model. As a novelty, it was investigated whether behavioral intention transforms into behavior in this study. In this context, it is the first study conducted in Turkey. Turkey is in the top three for pepper production in the world. In addition, pepper is among the agricultural products that use the most pesticides. This study aims to determine and explain Capia pepper farmers' pesticide reduction intention and pesticide use behaviors in Turkey. For this purpose, the pesticide use behaviors of farmers in the province of canakkale, which ranks first in Capia pepper production in Turkey, were analyzed with the Structural Equation Model. Face-to-face surveys were conducted with 206 Capia pepper farmers selected by a proportional sampling method. The research results show that subjective norms and attitudes are important determinants of farmers' willingness to reduce pesticide use. Likewise, perceived behavioral control is a unique factor in farmers' use of pesticides. However, farmers' intentions to reduce pesticide use were not reflected in their actions. It is important to increase awareness among farmers about pesticide behavior. Agricultural policy implications should be planned that target the perceived behavior, subjective norms, and attitudes of farmers regarding pesticide use.Öğe Determining the technical efficiency level of oily sunflower production by Stochastic Frontier Analysis (SFA) Method: the case of Thrace Region, Turkey(Univ Fed Rural Pernambuco, Dept Administracao, 2023) Semerci, ArifThis research aims to measure the efficiency in agricultural enterprises producing sunflower oil in Thrace Region and also to determine the causes of inefficiency. The data of the study have been obtained from 571 agricultural enterprises, which have been determined by using the Stratified Sampling Method, producing sunflower on an area of approximately 5400 hectares. Stochastic Frontier Analysis method has been used to measure the technical efficiency scores of the enterprises examined in the study. Data regarding five inputs is used in the function for Stochastic Frontier Analysis. Also five variables have been included in the technical inefficiency model. According to the results of the analysis, the efficiency scores of the examined enterprises ranged between 0.29 and 0.96, while the average efficiency score has been obtained as 0.80. According to these findings, an average enterprise predicts that sunflower yield can be increased by 17% without making a change in the amount of input it uses. However, it has been calculated that the enterprises operating at a minimum level can increase the sunflower yield by 70%. In the recent study, it has been determined that the sunflower yield per unit area is positively related to the use of seeds, labor and fuel, whereas it is negatively related to the use of fertilizers and pesticides. Findings, which have been obtained in the study, state that increasing the amount of seeds, labor and fuel will raise the amount of sunflower produced, while increasing the amount of fertilizer and pesticides used will cause a decrease in the amount of sunflower obtained. In the study, according to the gamma parameter calculated for the inefficiency model in oil sunflower production, it has been concluded that 91% of the variation in sunflower yield is caused by technical inefficiency. The coefficients of age, education and number of parcels in the inefficiency model are negative. This situation indicates that those enterprise owners who are older, have a higher education level, and have more parcels are more effective. However, the results of the research have revealed that the coefficient of the sunflower cultivation area variable has a positive sign and the inefficiency increases as the cultivation area raises in the examined enterprises.Öğe Cost and gross profit analysis in oily Sunflower (Helianthus Annuus, L .) Production: the case of Canakkale province, Turkey(Univ Fed Rural Pernambuco, Dept Administracao, 2023) Semerci, Arif; Yurt, İnanWorld sunflower production in 2019 amounted to 56 million tons on an area of about 27 million ha. Turkey ranks 9 th in sunflower cultivation areas worldwide and 7 th in production quantity. However, the self-sufficiency rate in the country's oily sunflower is 60%. This situation causes Turkey to receive a 33% share of world oily sunflower imports. The aim of this research is to determine the physical production inputs used in rainfed conditions in agricultural enterprises in Canakkale province located in the European region of Turkey according to the enterprise size groups and to examine in detail the elements that make up the product cost. The data used in the research have been obtained through surveys from 75 agricultural enterprises determined by the Stratified Sampling Method . The enterprises examined in the research have been evaluated within 4 size groups according to their oily sunflower production areas. In order to obtain an average yield of 236.93 kg da(-1) in oily sunflower production in the enterprises examined; 374.60 g seeds, 21.27 kg of chemical fertilizer, 297 cc of agricultural medicine, 147.58 minutes of machine labor force and 13.74 lt diesel input were needed. According to the enterprise average, the production cost of oily sunflower is $77.21 da(-1), and the lowest cost belongs to large enterprises with a figure of $74.17 da(-1). According to the research results, the average cost of oily sunflower per kg of enterprises has been determined as $0.33, and the lowest cost has been obtained from small businesses with a figure of $0.31 da(-1) . In the general context of the enterprises, the production value of oily sunflower is $86.61 da(-1) , gross profit is $33.60 da(-1) , net profit has been calculated as $9.40 da(-1) . In the study, the ratio of average gross profit value of oily sunflower to the production value of the product is 38.79%, and the relative profit ratio is1.12. In the study, it has been concluded that the average productivity value in sunflower production is 3.07 kg $(-1) and the break-even point value indicating land crossing in production is 208.68 kg da(-1) . The results of the study reveal that government -provided supports in the studied enterprises can provide an increase of 24.97% in the income generated from the unit area in sunflower. The research conducted have also revealed that the criteria of yield value, production value, cost per kg, gross profit and net profit and relative profit ratio are the highest in the first group of enterprises. In other words, the research findings showed that among the studied enterprises, small-scale enterprises work more efficiently and productively than the enterprises in other groups, but also behaved more rationally in the use of input.Öğe Determining the economic efficiency level of feed consumption in cow milk production(Univ Fed Rural Pernambuco, Dept Administracao, 2023) Semerci, ArifThis research has been carried out in order to determine the resource utilization efficiency of feeds and feed combinations that are predicted to affect the amount of cow's milk production. The data used in this research were obtained using the stratified sampling method. In this study it has been determined that the share of variable costs in milk production is 64%, and the share of feed in variable costs is 80%. In this research it has been found out that the degree of explaining the milk production amount of the variables in the estimation equation is 83%, and the F value for the equation is statistically significant at the 1% level. The sum of the elasticity coefficients of the factors in the estimation equation (Sigma beta i: 1.016) has shown increasing returns to scale in dairy cattle enterprises. Among the variables in the function, the factor with the highest efficiency coefficient has been found as the roughage input with 6.60. The results of the analysis has revealed that the use of resources in milk production on the basis of both factors and factor combinations is not efficient and rational.Öğe Sensitivity of Farmers to the Environment and Human Health in the Application of Agricultural Pesticides: A Case Study from Türkiye(Springer, 2024) Everest, Bengü; Özşahin, RefikPesticides are used extensively to control diseases and pests during crop production. The intensive use of pesticides pollutes soil and water resources. The increasing pollution of soil and water resources has become a global problem. The most significant factor influencing the outcome is the behavior of farmers in the process of pesticide use. Intensive use of pesticides not only pollutes the environment but also negatively affects human health. Therefore, farmers' sensitivity to the environment and human health is essential in regions where pesticides are used intensively. This study examined the behavior of farmers regarding pesticide use in the Lapseki district of T & uuml;rkiye, where fruit growing and pesticide use are intensive. The study was investigated using 93 questionnaires covering all villages in the Lapseki district. The surveys were conducted face-to-face with fruit producers. The data obtained were evaluated by logistic regression analysis. According to the results obtained, fruit producers in Lapseki district are moderately conscious of the use of pesticides. Only 42% of producers use pesticides according to the recommended dosage, but most of them know pesticides are harmful to the environment and human health. Therefore, it is essential to provide fruit producers in the region with training on pesticide use.Öğe Kekik Üretiminde Girdi Kullanımı ve Maliyet Analizi-Denizli İli Türkiye Örneği(Univ Namik Kemal, 2024) Semerci, Arif; Ken, EnverBu çalışma, Denizli ilinde yer alan tarım işletmelerinde kekik üretiminde girdi kullanımının belirlenmesi ve üretim maliyetinin incelenmesi amacıyla yapılmıştır. Araştırmada kullanılan veriler Basit Tesadüfî Örnekleme Yöntemi’ne göre belirlenen 82 adet tarım işletmesinden anket uygulamasıyla elde edilmiştir. İncelenen işletmelerde tarımsal gayrisafi üretim değerinin %60.57’si, bitkisel üretim deseninin %65.54’ü ve bitkisel üretim değerinin de %73.89’unu kekik ve kekikten elde edilen üretim değerleri oluşturmaktadır. İşletmelerde ortalama kekik üretim alanı 45 da olup, birim alandan elde edilen verim 95.10 kg da-1 olarak tespit edilmiştir. Araştırma bulguları birim alandan ortalama 95.10 kg kekik ürünü elde edilebilmesi için dekar başına; 10,296 adet fide, 8.93 cc zirai mücadele ilacı, 52.34 kg kimyevi gübre ve 16.57 lt mazot tüketilmesi gerektiğini, bununla birlikte 4.49 saat makine işgücü ve 17.84 saat insan işgücüne ihtiyaç duyulduğu tespit edilmiştir. Yürütülen çalışmada kekik üretiminin ortalama üretim değeri 1.494,02 TL da-1 olarak hesaplanmış, en yüksek kekik üretim değeri 1.691,00 TL da-1 ile birinci grupta yer alan işletmelerden elde edilmiştir. Yürütülen araştırmada birim alanda ortalama kekik üretim maliyeti 1.101,36 TL da-1 olarak tespit edilmiş, en yüksek ürün maliyeti 1.175,83 TL da-1 ile birinci grupta yer alan işletmelerde gerçekleşmiştir. İşletmeler ortalaması dikkate alındığında, birim alanda kekik üretiminin brüt kârı 882.74 TL da-1, net kârı 392.66 TL da-1 ve nispi kâr oranı ise 1.36 olarak hesaplanmıştır. Nispi kar oranı birinci (1.44) ve ikinci (1.45) grupta yer alan işletmelerde birbirine oldukça yakın iken, en düşük nispi kâr 1.29 ile üçüncü grupta yer alan işletmelerden elde edilmiştir. Yapılan araştırma Denizli ilinde kekik üretimine ilişkin tarımsal bir örgütlenmenin olmadığını göstermiştir. Bu durum işletmelerin kekik üretiminden elde edebileceği geliri kısıtlamaktadır. Bununla birlikte coğrafi tescilli bir ürün olan kekikte il özelinde markalaşmaya gidilmesi halinde kekik üreticilerinin gelirinin de artması mümkündür.Öğe Factors Affecting Consumers' Organic Agricultural Products Preferences in Turkey(Ondokuz Mayıs University, 2023) Aydın, Başak; Doğu, Murat; Kılınç, Ayten Aşkın; Demir, Sunay; Tarım, Bülent; Aktürk, Duygu; Pezikoğlu, FilizThis study was conducted with consumers consuming and not consuming organic products in six regions in Turkey classified in terms of development levels according to socio-economic development index values. The study aimed to compare the socio-economic aspects of consumers and to reveal the factors affecting the organic product purchasing behaviors of consumers. In the research, a survey was conducted with a total of 1494 consumers in 32 provinces, who consumed and did not consume organic products. Logistic regression analysis was used to analyze the factors affecting consumers' tendency to consume organic products. It was determined that consumers who consumed organic products were slightly younger than consumers who did not, and their monthly food expenditures were higher. It was determined that the education level of consumers who consumed organic products was higher. In addition, it was determined that the non-working and retired occupational groups were more dominant in the consumer group that did not consume organic products. According to the results, it was determined that the gender of the consumers, the education period, the presence of children in their households, the person doing the food shopping in the family, the monthly food expenditures, and the organic product consumption of the region they lived in affected the organic product consumption status positively.Öğe TR22 Bölgesinde İyi Tarım Uygulamaları Yapan Üreticilerin Çevre ve Küresel İklim Değişikliği Algısı(Tarımsal Ekonomi ve Politika Geliştirme Enstitüsü Müdürlüğü, 2023) Tan, Sibel; Taşçıoğlu, Ramazan; Aksoy, Yunus Emre; Özkan, SinemDünyada nüfus artışına bağlı olarak artan gıda ihtiyacı ile tarımsal üretim de giderek yaygınlaşmaktadır. İnsan odaklı bir faaliyet olarak tarım, karbondioksit (CO2) ve metan (CH4) gibi gazların emisyonlarının sebep olduğu sıcaklık artışı olarak tanımladığımız küresel iklim değişikliğinde hem etken hem edilgen rol oynamaktadır. Dolayısıyla Dünyada ve Türkiye’de tarımdan kaynaklanan sera gazı emisyon hacminin artışı çevre tahribatı açısından önemli riskler taşımaktadır. Bu riskleri azaltmak için tüm dünya ülkelerinde çeşitli tedbirler alınmakta ve politikalar uygulanmaktadır. Bu bağlamda çevre dostu üretim yöntemleri ön plana çıkmakta olup, İyi Tarım Uygulamaları (İTU) ilk sırada gelmektedir. Toprak, su, hava, bitki örtüsü ve doğal kaynakların korunmasına odaklanan İTU aynı zamanda kaliteli, güvenli ve sağlıklı gıda üretimini de amaçlar. Dolayısıyla İTU küresel iklim değişikliği ile mücadelede başarılı bir tarımsal üretim şeklidir. Ayrıca üretim şekli itibari ile üreticilerde oluşturduğu çevre ve iklim değişikliği farkındalığı açısından da önemlidir. Dünya genelinde İTU’nın giderek artması üretici tercihleri yansıra tüketici tercileri ve beklentisi de bu yöntemin gelişmesini teşvik etmektedir. Tüketicilerin gıda güvenliği konusundaki arayışları ve sürdürülebilir çevre endişeleri İTU’nı daha da önemli hale getirmektedir. Bu çalışmanın amacı İTU yapan üreticilerin küresel iklim değişikliği farkındalığının ve bilinç düzeyinin ölçülmesidir. Çalışmada İTU’ında üretici sayısının yaklaşık olarak yarısının yer aldığı TR22 bölgesindeki (Balıkesir, Çanakkale) 165 üretici ile anket yapılmıştır. Çalışmada üreticilerin küresel iklim krizinin tarım üzerine etkisinin daha çok algılandığı fakat tarımın iklim değişikliğine olumsuz etkilerinde üretici farkındalığının yeterli olmadığı tespit edilmiştir. Ayrıca İTU da pazarlama destek ve politikalarının gerekliliği tespit edilmiştir.Öğe Balık Değer Zincirinde Gıda Kaybı, Atıklar ve Çevresel Etkiler(Osmaniye Korkut Ata Üniversitesi, 2024) Türkten, Hatice; Yıldırım, Çağatay; Yüceer, Sema EzgiBalık, gıda kaybı ve atık açısından yüksek potansiyele sahip, çabuk bozulabilen bir üründür. Balık değer zincirinin her bir aşamasında önemli ölçüde gıda kaybı ve atık ortaya çıkmaktadır. Bu nedenle balık değer zincirindeki gıda kayıp ve atıkların tanınması, önlenmesi ve azaltılması büyük önem taşımaktadır. Çalışmada, Türkiye'nin İzmir ili Çeşme ilçesinde balık değer zinciri boyunca üretilen atık çeşitleri ve miktarını belirlemek, balık değer zincirinin çevresel etkinliğini tahmin etmek amaçlanmıştır. Araştırma veri kaynakları, balık tedarik zincirindeki ticari balık avcılarını, su ürünleri yetiştiricilerini, işleyicileri, toptancıları, ihracatçıları ve perakendecileri içermektedir. Çalışmada, araştırma alanında bulunan A, B, C plakalı tekne sahibi ticari balık avcıları, basit tesadüfi örnekleme yöntemiyle belirlenmiş, D plakalı 36 ticari balık işletmeleri, 8 adet su ürünleri yetiştiriciliği yapan işletmeler, bir adet balık işleme tesisi, limanlar, balıkçı barınakları ve balık satış noktalarından elde edilen veriler kullanılmıştır. Her düzeyde veri toplamak için 2023 üretim yılını temel alan anketler ve bireysel mülakatlar kullanılmıştır. Balık değer zincirinin toplam çevresel verimliliğini tahmin etmek için çok aşamalı ağ DEA modeli kullanılmıştır. Balık değer zincirindeki her bir aktörün sosyo- ekonomik özellikleri basit tanımlayıcı istatistik yöntemler ile ortaya konmuştur. İşletmelerin ekonomik analizinde, klasik ekonomik analiz yöntemi kullanılmıştır. Çalışmanın sonuçları, balık değer zincirinde üretilen atık miktarının işleme aşamasında en yüksek olduğunu göstermektedir. Ayrıca çevresel verimlilik analizi, değer zincirindeki aktörlerin çevresel verimlilik puanlarının 0,625 ile 1 arasında değiştiğini ortaya çıkarmıştır. Balık işleme aşamasında atık oluşumunun azaltılması, paydaşlar arasındaki iletişim ve koordinasyonun geliştirilmesi, gıda kaybı konusunda farkındalığın ve eğitimin artırılması gerekmektedir. Ayrıca atıkların önlenmesi için sürdürülebilir uygulamaların teşvik edilmesi önemlidir. Balık değer zincirindeki politika ve karar alma süreçlerine çevresel verimliliği artıran, gıda kaybı ve atıkları azaltmayı amaçlayan müdahaleler göz önünde bulundurulmalıdır.Öğe Socio-Economic Characteristics of Producers and Economic Size Classes of Enterprises According To Typologies and Risk Attitudes in TR21 Region(2024) Aydın, Başak; Öztürk, Ozan; Çebi, Ülviye; Özer, Osman Orkan; Aktürk, DuyguThe aim of this study was to determine the typologies of agricultural enterprises operating in the TR21 Region according to the Farm Accounting Data Network methodology and the risk attitudes of the producers. According to the typologies and risk attitudes of the enterprises, the socio-economic characteristics of the producers and the economic size classes of the enterprises were determined. As a result of sampling based on a 95% confidence interval and a 10% margin of error, the number of enterprises surveyed was determined as 334. While 63.77% of the enterprises were specialized in field crops, 25.45% engaged in mixed livestock and plant production. Additionally, 7.49% were specialized in pasture livestock and 3.29% were in the perennial plant farming group. In the enterprises examined, 55.09% of the producers were classified as risk-averse and 44.91% as risk-lover. Of the average land holdings, 71.25% was property and 28.75% was rented land. It was noteworthy that the land rental rate in risk-lover enterprises was higher than in risk-averse enterprises. It was concluded that risk-lover enterprises had higher production value in both plant production and animal production, and risk-averse enterprises were engaged with product and animal diversity as they avoided taking risks. On average, in risk-lover enterprises, 53.64% of the operating expenses were vegetative special expenses and 46.36% were animal special expenses. In risk-averse enterprises, the share of vegetative special expenses in total expenses was 47.15%, and the share of animal special expenses was 52.85%. Compared to the average of enterprises and all enterprise typologies, standard gross profit was found to be higher in risk-lover enterprises. In enterprise typology groups, the average ESU values of the enterprises varied between 10.88 and 33.80 ESU. According to enterprise typologies, risk-averse agricultural enterprises in specialized field crop farming and perennial plant farming were in the below-medium enterprise class, while other enterprise groups were in the above-medium enterprise class.Öğe Şeker Pancarı Üretiminde Kaynak Kullanım Etkinliğinin Analizi: Balıkesir İli Örneği(2024) Semerci, Arif; Ural, MusabDünyada ve Türkiye’de şeker pancarı üretimi; ekonomiye yaptığı pozitif etki yanında, yan sanayilere hammadde sağlaması, hayvansal üretimi teşvik etmesi nedeniyle önemli bir tarımsal faaliyet dalıdır. 2019/2020 döneminde dünya şeker üretimi 167 milyon ton olarak gerçekleşmiş olup, şeker pancarı üretiminde Türkiye Avrupa kıtasında 4. ve dünyada ise 5. ülke konumundadır. Tarımsal üretimde en önemli konuların başında üretim maliyeti ve girdilerin etkin kullanımı gelmektedir. Etkin kullanılmayan girdi ürün maliyetini artırdığı gibi faaliyet dalının rekabet gücünü de azaltmaktadır. Bu çalışmada Balıkesir ilinde Tam Sayım Yöntemi ile belirlenen 75 işletmeden elde edilen veriler yardımıyla şeker pancarı üretiminde girdi kullanım etkinliği analiz edilmiştir. İncelenen işletmelerde şeker pancarı ortalama ekim alanı 11.70 da olup, birim alandan elde edilen verim ise 7326.49 kg da-1 olarak tespit edilmiştir. Çalışmada şeker pancarı üretimine ilişkin oluşturulan fonksiyonda; gübre ve işgücü değişkenine ait üretim elastikiyeti katsayısı %1, tohum kullanım miktarı ve sulama sayısı faktörleri %5, tarımsal mücadele ilacı kullanım miktarı ve çapalama sayısı değişkenleri ise %10 ihtimal düzeyinde önemli bulunmuştur. Tahmin fonksiyona ilişkin üretim elastikiyetleri katsayıları toplamı (??i: 1.048) ölçeğe artan getiriyi vermektedir. Denklemde en yüksek marjinal etkinlik katsayısı (3.91) gübre değişkenine aittir. Yürütülen araştırmada faktörlerin marjinal etkinlik katsayılarına göre incelenen işletmelerde şeker pancarı üretiminin artırabilmesi için birim alanda kullanılan gübre (X2), tarımsal mücadele ilacı (X3) ve çapalama sayısının (X6) artırılması gerektiğini göstermiştir. Araştırma sonuçları şeker pancarı üretiminde sulama sayısı değişkeninin (X5) 0.88 katsayısı ile ekonomik optimum düzeye en yakın girdi olduğu tespit edilmiştir. Bununla birlikte incelenen işletmelerin girdi kullanımında etkin olmadığı bu nedenle şeker pancarından sağlanan gelir üzerinde bu durumun olumsuz etki ettiği sonucuna varılmıştır. Yapılan araştırma şeker pancarı üretiminde daha yüksek verim ve daha karlı üretim yapılabilmesi için mutlaka üretim faktörlerinin etkin kullanılması gerektiğini ortaya koymuştur.Öğe Bitkisel Üretimde İşletme Büyüklüğünün Ürün Verimi, Üretim Değeri ve Ürün Maliyeti Üzerine Etkisi: Çeltik, Pamuk ve Kanola Üretimi Örneği(2024) Semerci, ArifTarım ürünleri ticaretinde ve ülkelerarası rekabet bağlamında birim alandan elde edilen verimin yüksekliği yanında üretilen ürünün maliyeti de önemli rol oynamaktadır. Bir tarım işletmesinin hem verim hem de maliyet avantajına sahip olabilmesi için belirli bir işletme büyüklüğüne sahip olması gerekmektedir. Bu çalışmada; pamuk üretiminde 136 işletmeden, çeltik üretiminde 74 işletmeden ve kanola üretiminde de 83 işletmeden elde edilen veriler işletme büyüklük grupları bazında verim değerleri ve ürün maliyetleri dikkate alınarak analiz edilmiştir. İncelenen işletmelerde işletme başına ortalama üretim alanları kanolada 83.14 da, çeltik üretiminde 141.36 da ve pamuk üretiminde ise 107.99 da olarak belirlenmiştir. Araştırmada; Çeltik üretiminde işletme başına ortalama verim 777.11 kg da-1 olup, en yüksek verim (797.20 kg da-1) ve ürün değeri ($446.46 da-1) büyük işletme büyük grupta yer alan işletmelerden sağlanmıştır. Yürütülen araştırmada pamuk üretiminde işletme başına ortalama verim 536.19 kg da-1, kanola üretimde ise 290.87 kg da-1 olarak hesaplanmıştır. Yapılan araştırma en yüksek verimin kanola üretiminde (309.23 kg da-1) ve pamuk üretiminde (538.53 kg da-1) küçük işletmelerin bulunduğu birinci gruptan elde edildiğini göstermiştir. Araştırma kapsamında işletme yöneticilerininin yaşı, mesleki tecrübesi ve genel eğitim düzeyi de işletme büyüklük grupları bazında analiz edilmiştir. Araştırma bulguları çeltik üretiminde üreticilerin ekonomi ilkelerine uygun olarak, diğer bir ifade ile rasyonel bir şekilde, işletmelerini yönettiklerini ortaya koymuştur. Pamuk ve kanola üreten işletmeler ise küçük işletme gruplarında hem verim hem de üretim değeri bakımından diğer gruplarda yer alan işletmelere göre daha yüksek performans göstermişlerdir. Bu durum pamuk ve kanola üretiminde orta ve büyük grupta yer alan işletmelerin büyük ölçekli işletme olmanın avantajlarından yeterince yararlanamadıklarını ortaya koymuştur.
