چکیده مقاله:

In recent years, food security, which can be defined as the condition of having enough food to provide adequate nutrition for a healthy life, is a critical issue in the developing world (Hosseinzadeh-Bandbafha et al., 2017). Energy is one of the important elements in modern agriculture as it depends heavily on fossil and other energy resources, it is used in all facets of living and in all countries, and makes possible the existence of ecosystems, human civilizations and life itself (Safa and Samarasinghe, 2011). Energy consumption in agriculture has been increasing in response to the limited supplies of arable land, population growth, technological changes, and a desire for higher standards of living (Kizilaslan, 2009). Therefore increasing the use of energy inputs in agriculture led to numerous environmental problems like high consumption of non-renewable energy resources, loss of biodiversity, pollution of the aquatic environment by the nutrients nitrogen and phosphorus as well as by pesticides (Nemecek et al., 2011). Evaluation of energy efficiency in the production process is the first step for optimal using of available resources (Taki et al., 2012). By identifying the share of energy consumption in each level, it is possible to provide reasonable energy consumption strategies and make a good decision for reducing the energy consumption (Taki et al., 2013). Energy analyze for studying final efficiency and environmental impacts of crop productions is important approach in agriculture and can play a significant role for improving the quality of decision-making, management and development of this sector. Importance and necessity of this subject encouraged many researchers for analyzing the energy efficiency in agricultural productions. In most of these researches, the authors evaluated the energy consumption in agriculcher productions based on the input-output energy flow, but the input-output energy analysis method is used for crop production, the quality of the inputs will not consider as an important key factor (. To overcome this limitation, Cumulative Energy Demand (CED) analysis can be used as an innovative idea. One of the most effective methods for energy analysis is Cumulative Energy Demand (CED). CED is a consistent approach, which quantifies the energy content of all different (renewable and non-renewable) energy resources. The main questions related to CED indicator are the following (Frischknecht et al., 2015):- How to define appropriate energy values for the different energy resources (lower or upper heating value, energy content of uranium) - Should the cumulative energy demand include energy and material related consumption of energy resources and if so, how should material related share of consumption be calculated - Does the cumulative energy demand deal with final energy demand or with the resource aspect of primary energies Due to the importance of agricultural consumption in agricultural minerals and especially energy consumption in garden products, extensive studies have been done on the input and output energy analysis in the production of horticultural products. (Mardani and Taghavifar, 2016; Kızılaslan, 2009; Strapatsa et al., 2006). But based on the literature, there has been no study on application of CED for apple production in Iran. Hence, the present study is a combination of the life cycle inventory of apple production with the concept of energy, which explores the consumption of energy and energy usage reduction opportunities with the CED method in apple production.
