Technical, economic and environmental review of development of solar irrigation systems in agriculture sector of Fars province, Iran

The phenomenon of climate change as a threat to sustainable management has had the greatest impact on the increase in carbon dioxide production. Iran is considering the ninth place of carbon dioxide production in order to reduce emissions. Fars Province, with the first rank of water consumption and agricultural production in the country, has the highest production of carbon dioxide in agriculture through water pumping. The six scenarios in solution using solar pumps or replacing diesel pumps with electric pumps connected to the network, the changes in carbon dioxide were studied. In order to determine the amount of contamination, the results of relevant research were used based on the life cycle assessment method. Comparison of electric pumps connected to the network with diesel pumps results in a reduction of emissions of 8% and an increasing the cost of up to 26.7% due to higher efficiency. The use of solar power, despite less pollution by 16.6%, leads to a higher cost of 74.4%. By reviewing the price of energy carriers in Iran and comparing it with the countries of the region, including Turkey, the second three scenarios were examined. Therefore, the economic justification for using grid electricity was more intense than using diesel fuel, but it showed a smaller difference in electric power consumption by using grid electricity.
