Consumer demand for organic foods has increased significantly in recent years in the world. Consumers are influenced by various internal/external factors when purchasing food products. The aim of this study is to determine the effects of knowledge variable on consumers' purchasing or consuming behavior for organic foods together with other factors in Turkey (Hatay City). For this purpose, the effects of consumers' organic product knowledge levels are examined within the frame of Theory of Planned Behavior. The data of 431 consumers analyzed in the model were collected in 2017 with a 21 scale questionnaire and analyzed with Structural Equation Model. According to the results of the model analysis, a significant part of the variance in consumers' organic food demand (61%) was explained by the organic food knowledge variable. Reducing consumption obstacles, along with efforts to increase the organic food knowledge of consumers, will increase organic demand. While trying to increase the supply of organic products especially in regions where consumers are concentrated, the food production sector should also focus on informing, raising awareness and promoting. The actual buying behavior in organic food products should be examined in more detail in terms of motivation sources and obstacles.

In this study, it was aimed to determine the reasons for the waste of bread among consumers in Hatay province and what should be taken for the elimination of these causes. The subjects of this study were the data obtained from 406 consumers selected from the city center. The data were obtained through face to face interviews during the period of May-2017. In the questionnaire, there were questions towards determining the bread consumption habits, consumption preferences and bread waste levels along with the socio-demographic characteristics of the consumers. Cross tabulation and chi-square analysis were used in the evaluation and comparison of the data. It was determined that the amount of bread consumed per person was 278 g/day and 7% of the total family consumption of bread was wasted without any consumption. While the most consumed types of bread are traditional white bread and flatbread, bakeries and groceries are the most common places to buy bread. Consumers usually buy bread twice a day and the main considerations in the consumers’ preference for bread purchase are that the establishments comply with hygiene requirements and that quality materials are used in the bread making process. Staling and bad taste are among the significant issues in bread wastage. Taking future trends in the sector into consideration, producers should pay attention to product quality, production according to health conditions and longer shelf life on bread; depending on consumer awareness. The producers should diversify their production of bread and other bakery products.

The rapid increase of the red meat price in Turkey in the recent years negatively affects its consumption. Consumers are seeking to compensate for the need for animal protein with cheaper substitution products. In this study, the effects of consumer attitudes, product prices and some other variables on the factors affecting consumption of fresh red meat are examined. A 58‑item questionnaire measuring Behavior and Behavioral Intention was applied to 455 consumers in the Eastern Mediterranean Region of Turkey based on the Theory of Planned Behavior. In the study, participants’ consumption of fresh red meat and white meat was examined together. In the analysis of the data, correlation, independent samples’ t‑test and One Way Anova was used together with Path Analysis which is a Structural Equation Model technique. Price increases have a negative impact on fresh meat consumption and the effect on consumption of red meat is much higher. The Structural Model explains 80 % of the Behavioral Intention variance and 87 % of the Behavioral variance. In consumers’ Behavior and Behavioral Intention in meat consumption Attitude, Perceived Behavioral Control and Price variable have a significant influence, while the effect of Subjective Norms on a lower level. Socioeconomic and demographic variables cause significant differences in fresh meat consumption. Reducing the increases in input prices, which is the most important source of the increase in red meat prices in Turkey, in the short and medium terms, and supporting the supply increases by sustaining its implementation in the medium and long terms should be adopted as basic policies.

New Ecological Paradigm Scale (NEP) is commonly used to determine people’s environmental opinion and their behaviors about it. Environment-friendly and sustainable agricultural production techniques are one of the most important issue in agricultural engineering. In this study, agricultural engineer candidates’ environmental behaviors were determined by using of NEP scale. Data was collected from 350 undergraduate students in 2015-2016 school year. Environmental behavior mean was found as 3,38 that indicates slightly better than average environmental behavior. Four sub dimensions were determined with Explanatory Factor Analysis and variance was found 68%. According to First and Second-Order Confirmatory Factor Analysis, data showed results that confirm models. Second-Order Confirmatory Factor Analysis explanatory rate was found 78%. Despite all technological development, mankind still under the influence of natural laws and there is a serious environmental degradation by human activities. Agricultural engineer candidates showed a behavior that is balanced between environmental awareness and meeting humans’ nutrition needs.
