Abstract

Significant methods have been made in the method of ecological footprint, which Eemergitic Ecological Footprint (EEF) is one of them. In the last decade Emergy accounting has been introduced to improve the ecological footprint calculations. In this research by combining the two methods, time trends of cereal Eemegitic Ecological Footprint (EEF) of Iran and Iran’s provinces during 2001-2013 were analyses. Results indicate that during the studied period cereal EEF of Iran was along with fluctuations, which reached from 0.85 ha/person in 2001 to 0.4 ha/person in 2011 and then increased to 0.7 ha/person in 2013. Average EEF of wheat, barley, rice and corn of the country during the period 2011-2013 were estimated respectively, by 0.36, 0.09, 0.09 and 0.08 ha/person per year. The highest and lowest value of cereal EEF in provinces of Iran were obtained respectively Sistan Baluchestan (Eemergitic Ecological Footprint of wheat, barley, rice and corn respectively, by 2.81, 0.63, 0.58, 0.52 ha/person per year) and Gilan (Eemergitic Ecological Footprint of wheat 0.13 ha/person per year and barley, rice and corn each, 0.03 ha/person per year.). Considering that the average cereal EEF of Iran was 0.62 ha/person per year, more provinces were higher than the average cereal EEF of the country. The provinces had a low local renewable emergy density (p). This result indicates that exist pressure on renewable resources in the production and supply of food, especially cereal in the country.
