A graphical approach for the design of heat-integrated water systems has been proposed to improve conceptual understanding for implications of heat recovery in water systems, as well as to provide systematic design guidelines for selecting most appropriate integrated options in practice. The...

Efficient use of energy in agriculture is one of the conditions for sustainable production. In the present study energy use pattern for tomato production in Iran was investigated and a non-parametric data envelopment analysis (DEA) technique was applied to analyze the technical and scale...

By using output distance functions, this paper decomposes energy productivity change into several components: effects of the changes in the ratios of non-energy inputs to energy, energy supply composition, and output composition; technical efficiency change; technological change. We apply this...

One of the main concepts of tillage should be to create the most appropriate soil conditions by taking into consideration energy use efficiency because it allows financial savings, fossil resources preservation and environment pollution decrease. Therefore, the study was perform to evaluate the...

Wheat is the second most important cereal crop in Bangladesh and production is highly sensitive to variations in the environment. We estimate productivity and energy efficiency of wheat farming in Bangladesh by applying a stochastic production frontier approach while accounting for the...

The objectives of this study were to evaluate the energy consumption of inputs and outputs used in the sugar beet production system and to determine the relationship between energy inputs and yield in Iran. To achieve these objectives, data were collected from 153 sugar beet farms selected using...

‘Gher’ farming is a unique system that incorporates the joint operation of three enterprises: freshwater prawn, fish and HYV rice, and is expanding rapidly in the coastal regions of Bangladesh because of its proven high income earning potential. In this paper, the sustainability of this...

In this study, a survey and economic analysis regarding the use of input have been performed with canola farmers in the Trakya region of Turkey; survey data were obtained from 100 farmers, face-to-face. The average energy use efficiency is 4.68 and this value increases as farm size increases;...
