The purpose of this paper is to analyze the efficiency of input use in tobacco production in Turkey with respect to sustainability. In the construction of cross sectional data, the provinces in the Aegean, Northwestern, Eastern-Southeastern Anatolian and Black Sea regions were considered. Face to face interviews were carried out with 300 farmers from the provinces which together produce at least 75% of regional tobacco output. Efficiency measures of tobacco farms in each region were calculated by Data Envelopment Analysis (DEA). Efficiency measures obtained from constant return to scale DEA were then decomposed into pure technical efficiency and scale efficiency. Total tobacco production (in kg) was used as the output indicator, and land (ha), labor (hours), tractor use (hours), nitrogen (kg), phosphorus (kg) and pesticide (kg) were considered as the main inputs. Econometric models were developed in order to determine the factors that affect the efficiency of regional tobacco production. The average technical efficiency score for all regions was found to be 0.456, implying that the same level of production per plots can be obtained even if the inputs used for tobacco produc-C. Abay

This study sets out to examine the influence of consumers’ green values on food‐related behaviours. Data were collected from a random sample of 385 consumers in Izmir, Turkey via face‐to‐face interviews. Factor analysis was conducted to identify the underlying dimensions that capture the meaning of green values, which affect shopping, cooking and eating behaviours of consumers. A composite variable that represents consumers’ perception of green values was created to classify consumers into two segments labelled: Negative perceivers (37.7%) and positive perceivers (62.3%). The results indicated that the positive perceivers tended to have healthier and environmentally friendly food consumption behaviours than the negative perceivers. Gender, age, education, marital status, body mass index, regular exercise and smoking were significant for differentiating between the segments. We intend to construct value‐based intervention programmes that are easy to implement, non‐mandatory and cost‐effective for the negative perceivers.

Res., 37: 213-216.Efficiencies of farms were measured using data envolepment analysis (DEA) on 87 dairy farms in hmir, Turkey. Technical, allocative and economic efficiencies were 0.615, 0.673 and 0.488, respectively. Only three farms were eficient. 62% of farms had decreasing return to scale. It is concluded that the current gross production value could be preserved while decreasing the number of cows, labor (man-days) and maize silage (kg) by 50.29, 45.1 7 and 42.42%, respectively.
