| At the same time as entering the third millennium and with increasing population, in many countries demand for water in order to supply dem world population needs has increased considerably. But because of scarcity of water resources and water crisis in intire world the concept of water security and water poverty persresented into the economic literature of countries wich facing water crisis. Water poverty is one of the greatest challenges of this century and the multidimensional crisis of the next incoming decades in the world, especially in countries with low lelvel of water resources. This crisis can lead to many changes in the world. In this paper, unlike the usual methods op other lasr aricles to calculate water poverty, we calculate the water poverty index is on the base of Catastrophe theory multi-criteria evaluation system and mathematical fuzzy logic method. The sub-indices wich used to calculate the water poverty are including: water resources (water deficit ratio, surface water supply ratio, the proportion of other factors in water supply), access to water (per capita water resources, price elasticity of water demand, Gini coefficient for domestic use), capacity of Underground aquifers (groundwater utilization rates, surface water utilization rates, dilution rates), using of water resources (per capita consumption of water for irrigation in the agricultural sector, per capita consumption of drinking water, per capita consumption of water in Industrial sector) and environmental integrity (surface water drying, desertification rate, create desert rate). The results of calculating the water poverty index during the period from 1989 to 2015 indicate the upward trend of this indicator and its subset components, which indicates the worsening of the state of water security in Iran in recent years and possibly the deterioration and continuation of this complicated situation for next decades. In the other hand, as the current trend continues, both in terms of resources and in terms of managing the production and consumption of the country's water resources, Iran is gradually losing its ground and becoming poorer in terms of water resources. |
