An Analysis of Input Use Efficiency in Tobacco Production with Respect to Sustainability: The Case Study of Turkey

Abstract

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

Productivity and efficiency scores of dairy farms: the case of Turkey

“…However, these are separate concepts which should not be replaced. In an enterprise with efficient production levels, an increase in the productivity would not be expected, while an enterprise with increased productivity levels may not be an efficient one (Abay et al 2004). An important point to consider when measuring productivity and efficiency is the definition of productivity used by the manager or the researcher, and the selection of the outputs and inputs used as the indicators of productivity (Donthu et al 2005).…”

“…They showed that DEA is more robust than the parametric approach in measuring the productive efficiencies. Abay et al (2004) studied the efficiency of energy consumption in tobacco production in Chauhan et al (2006) used the DEA method to study the efficiency of rice farms in terms of energy consumption. They showed that 11.6% of input energy could be saved in these farms.…”

“…In another work, Abay et al (2004) analysed DEA CCR efficiency measurements of input use in tobacco production in Turkey with respect to sustainability. The authors carried out face-to-face interviews with some 300 farmers.…”

“…Some authors have proposed the use of DEA models to measure agricultural sustainability as, for instance, Kim (2001), De Koeijer et al (2002, Abay et al (2004), Rodríguez-Díaz et al (2004), Bosetti and Locatelli (2006), Sauer and Abdallah (2007). These studies are briefly described in Sect.…”
