In this study the amount of energy consumption and its relation with yield in producing two cultivars of plum, Ghatreh Tala and Shablon cultivars, in Tehran province of Iran were studied. For each one of plum cultivars, data were obtained from 100 farmers in the form of personal interview using...

In this study the energy and economic flows and greenhouse gas (GHG) emissions of olive oil production in Iran were investigated in terms of a life cycle assessment with considering four main stages of agricultural olive production, olive transportation, olive oil extraction and its oil...

Efficient use of energy resources in crop production is an important goal in sustainable agriculture. This study compares the energy flow in farming systems across farm size with their corresponding greenhouse gas (GHG) emissions - presented in terms of carbon dioxide equivalent (CO2 eq.) - in...

In recent years, besides the energy issues, the GHG (greenhouse gas) emission, which is the most important cause of global warming, has received high attention. In order to have sustainable development, it is necessary to manage energy usage and GHG emissions in all production processes. This...

Among the different forms of clean energies, solar energy has attracted a lot of attention because it is not only sustainable, but also is renewable and this means that we will never run out of it but the potential of using this form of renewable energy depends on its accessibility. Due to the...

In this paper, Data Envelopment Analysis (DEA) technique was applied for apple (Red and Golden delicious varieties) producers in West Azarbaijan province, Iran (2008-2009). Results showed that the highest share of energy consumption belongs to packaging (57%) and irrigation (16%). Highest share...
