| Popis: | Iran with arid and semi-arid climate needs to save water and energy resources. In this study, the two regions of Isfahan and Yazd as two critical points in terms of water and energy have been studied. In this research, the two-region Input-Output model is used to measure and analyze the water and energy relations between the economic sectors of Isfahan and Yazd provinces and the link model is used to investigate the hybrid flow of two sources and the extent of link effects in each region in 2016. The results of combined water and energy flow indicate that the two sectors "water, electricity and gas" and "agriculture" are the most consuming sectors or the most effective sectors in terms of consumption in two regions, so that the most important management node in the relationship between water and energy are considered. Also, the calculations made in the total flow section of the two sources of water and energy indicate that the two sectors "water, electricity and gas" and "coke production, products from oil refining and nuclear fuels, and manufacturing of chemical materials and products” account for the highest output (export) and input (import) of water and energy from other sectors, respectively. In addition, "Building" and "water, electricity and gas" are the most important sectors in water and energy imports, respectively. The total flow of water and energy resources between Isfahan and Yazd provinces indicate that each economic sector of Isfahan province is an exporter in the field of water and energy importing from other sectors, and each economic sector of Yazd province is an importer in the field of water and energy. |
