The change in income level and urbanization bring a different dimension to the demand to agricultural products from the food habits to supply food, increase the attention to the cereals production and enhance the agricultural effect of cereals which are the main food source of people and are used as feed and in industry. Cereals have the biggest share in agricultural production in terms of both production volume and sowing area in Turkey which produces a lot of agricultural products thanks to the climate and soil characteristics. In this study, in Turkey which is globally an important actor in cereals production and trade, the aims of producers in agricultural production and the factors in the process of making decision toward sustaining production are studied by the best-worst analysis method. Also, the relationship between the sustainability of the agriculture and cereals production, and the individual characteristics and farm structures of producers are examined by bivariate probit analysis method. In this context, study is conducted by 961 producers with face-to-face surveys in 14 provinces. According to the results, while “to increase living standards” is the most important agricultural aim, “good crop price” is the most important factor for sustainability of the agriculture. Moreover, education, agricultural experiences, household size, cereals area and total farm land are determined as the effective factors on sustainability.
Bu arastirmanin amaci Ankara Ili Polatli Ilcesinde ureticilerin tarim sigortasi yaptirmaya karar verme surecinde etkili olan faktorlerin belirlenmesidir. Soz konusu faktorlerin belirlenmesi sirasinda, tarim sigortalarinin desteklenmesine yonelik uygulamalar da dikkate alinarak, ortaya cikan ekonomik nitelikteki bu degiskenin ureticilerin karar verme surecindeki etkisi de incelenmistir.Arastirma tarim sigortalarinin yogun olarak yapildigi 20 koyden 157 uretici ile yapilmistir. Bu ureticilerden 71’i tarim sigortasi yaptiran, 86’si ise tarim sigortasi yaptirmayan ureticilerdir. Verilerin toplanmasinda anket yontemi, elde edilen verilerin istatistiksel analizinde ise lojistik regresyon yontemi kullanilmistir. Arastirmada, en az degiskeni kullanarak en iyi uyuma sahip olacak sekilde bagimli ile bagimsiz degiskenler arasindaki iliskiyi tanimlayabilen ve istatistiksel olarak kabul edilebilir bir model kurulmustur. Bu modelde bagimli degisken olarak tarim sigortasi yaptirma/yaptirmama, bagimsiz degiskenler olarak da bireysel nitelikler, isletme ozellikleri, haberlesme davranislari ve tarim sigortasina karsi tutum ele alinmistir.Arastirma sonuclari, bireysel niteliklerden kredi kullanimi ve tarim disi gelirin, isletme ozelliklerinden hayvan varligi ve seker pancari ekim alaninin tarim sigortasi yaptirmaya karar vermede etkili olan faktorler oldugunu gostermistir. Ayrica devlet tarafindan verilen tarim sigortasi prim desteginin tarim sigortasina karar vermede etkili oldugu da belirlenmistir.
This study was carried out in order to analyze seafood consumption level of consumers in Central Anatolia Region (Province Ankara) and their consumption behavior. Proportional sampling method was used in determining sample size and sample size was determined as 167. Data were collected from randomly chosen individuals with face-to-face interviews. As a result of study, in order to determine possible effects of socio-economic properties of consumers on seafood consumption, CHAID analysis which is one of the decision tree analyses was used. According to the results of analysis; it can be said that dependent variables of income, education and age have effect on attitude and behavior of consumers while gender have no effect on consumption behaviors.
Land use is a remarkable human-induced change that has redesigned the Earth’s surface since the beginning of civilization. Due to the combination of rugged terrain and low-income levels in rural areas, people in watershed regions often resort to overexploiting forests, agricultural land, and grasslands beyond their capacity. As a result of these spatio-temporal changes in land use, various soil properties undergo changes. This study aims to determine the changes in some physical (texture, bulk weight, particle density, total porosity), hydro-physical (water holding capacity, permeability, field capacity, wilting point), physico-chemical (organic matter, pH, electrical conductivity), and erodibility (dispersion ratio, colloid–moisture equivalent ratio, erosion ratio, clay ratio, aggregate stability and K-factor of Universal Soil Loss Equation-USLE) properties of soil depending on land use in the Deviskel Watershed in the city of Artvin in Türkiye. For this purpose, disturbed (composite) and undisturbed (cylinder) soil samples were taken from a 0 to 20 cm depth at 108 different points in the determined areas (36 from forests, 36 from agricultural areas, and 36 from grassland areas). It was determined that 15 of the 19 soil properties examined showed statistical differences depending on the change in land use. All the examined soil properties, except for clay content, particle density, dispersion ratio, and aggregate stability, were found to be statistically significantly affected by the change in land use, and the reasons behind these changes were discussed. The particle density had the lowest coefficient of variation value (15.26%) while electrical conductivity had the highest coefficient of variation value (91.25%). According to erosion tendencies, all watershed soils were found to be susceptible to erosion. The average aggregate stability was 88.52% in forest soils, 84.84% in agricultural soils, and 85.48% in grassland soils. The average USLE-K factor was determined to be 0.22 for forests, while it was determined to be 0.17 and 0.18 for agriculture and grassland areas, respectively. According to the USLE-K factor, 68.37% of the watershed was dominated by moderately erodible soils, while 31.63% consisted of highly erodible soils. Based on the colloid–moisture equivalent ratio, erosion ratio, and clay ratio, which are statistically different erodibility features, the grassland soils of the research area were found to be more susceptible to erosion than forest and agricultural soils. In terms of aggregate stability, which indicates resistance to water erosion, forest areas had higher values, while agricultural lands were more prone to erosion.
