“…Similar issues with low efficiency energy consumption in production of various crops in developing countries, including Iran, have previously been reported (e.g. Canakci & Akinici, 2006;Ozkan et al, 2007;Mohammadi & Omid, 2010). However, new policies by the Iranian government aim to gradually eliminate subsidization of fossil fuels which may put pressure on growers to implement more energy efficient practices.…”

Pistachio is considered as an important agricultural commodity in Iran and ranks top amongst all exported agricultural products. Conducting an overall energy audit and economic analysis of pistachio production can provide useful information to help implement management strategies for improving energy efficiency. A study was conducted during 2009 and 2010 to evaluate the overall energy inputs and outputs and to perform an economic analysis of pistachio production in the Iranian province of Markazi. The results revealed that the total energy input for pistachio production was 54305 MJ ha -1 . Electricity, followed by diesel fuel and nitrogen fertilizer application were the highest contributors to energy input in pistachio orchards. The contribution of direct energy was higher than indirect energy and share of non-renewable energy was more than renewable energy. Net energy, energy use efficiency, energy productivity and specific energy were 7522 MJ ha -1 , 0.86, 0.08 kg MJ -1 and 13.69 MJ kg -1 , respectively. Econometric model based on Cobb-Douglas function indicated that impacts of electricity, diesel fuel and chemical fertilizer energy inputs on pistachio yield were positive while the impact of machinery was negative. The marginal physical productivity (MPP) value for diesel fuel was the highest among other variables, followed by energy inputs related to the chemicals and irrigation water. The results revealed that production of pistachios in Markazi Province, under current management practices, are not energy efficient and efforts should be made to improve energy use efficiency.Additional key words: econometric model; energy use efficiency; renewable energy; sustainability.

Abstract. The aim of this study is to determine energy consumption of input and output used in raisin production and making a cost analysis in Aegean Region. Energy output-input analysis is generally done to determine the scope of environment and energy efficiency of agricultural production. In this study the cost of raisin production was calculated by Manisa Viticulture Research Institute's records in 2015. Costs of inputs and prices of raisin were obtained from various sources such as Turkish Statistical Institute, Aegean Exporters' Association and Turkish Ministry of Food, Agriculture and Livestock. The total energy input necessity for raisin production was 39,066.91 MJ/ha. The research results indicated that the total energy input used for raisin was mainly dependent on non-renewable energy forms (%97). The high ratio of non-renewable energy in the total used energy inputs causes negative effects on the sustainability in agricultural production. Among input energy sources, diesel oil, chemical fertilizers and electricity contained highest energy shares with 34.30%, 26.96%, and 22.50% respectively. The energy ratio and energy productivity were found to be 6.04 and 0.51 kg/MJ. Gross production value and total variable costs for raisin were $ 8,600 and $ 4,528.25, respectively. As a result of cost analysis, gross margin was calculated as $ 4,071.75.

“…In order to calculate the energy used on-farm, a range of data was collected pertaining to irrigation methods, water use and energy consumed for pumping and pressurizing systems, land preparation, machinery operations and fertiliser and chemical application. These inputs were selected based on common categories for the consideration of energy inputs as used in previous studies [7,8]. Energy categories include diesel, electricity, machinery hours, chemicals, fertiliser and seed.…”

Irrigated agriculture is an essential tool for increasing food production to meet global demand. However, along with benefits of high yields there are environmental impacts that must be considered. The tendency in Australia to evaluate irrigation systems in terms of water use efficiency only is problematic, and the criteria used to assess the sustainability of agricultural systems should reflect broader issues. A representative broad acre farm in the south east of Australia was used as a case study to explore the different resource consumption patterns and environmental impacts of flood, centre pivot and sub-surface drip irrigation methods. The energy and water consumption of each method was determined, along with greenhouse gas emissions and groundwater impacts, and the systems then ranked in order of highest to lowest resource use efficiency and environmental impact. It was found that when an irrigated system was evaluated by more than just water use efficiency, its ranking often changed. This method also allowed for the identification of areas where improvements could be made. Assessing irrigation methods and their appropriate selection for a given situation can aid in efficient and environmentally sound production systems at the local and global scale.
