  7. Abstract:
  8. There is increasing demand for water due to rising world population. In addition, lower supplies of water under varying hydrological condition because of changing climate, renders further stress on an already over-allocated water resource. Thus, this condition would exacerbate water supply-demand conflicts resulting in penalties on local economy. On the other hand fresh water as a scarce resource requires comprehensive management. To maintain fresh water resources, systems need principles of ecologically sustainable development that keeps environmental uses as legal. Hence, in this situation there is a need to develop appropriate methods to minimize the climate change consequences and address water deficiency problems.
    Water trading without significant investment, as constructing infrastructure to store water, has been accepted as an efficient and economical method to deal with water shortage problems.
    Based on this assumption that water will be optimally allocated for both climates, the effects of climate change have been evaluated. However, the random nature of water availability can complicate optimal water allocations. This study intends to develop a technique to evaluate the long-term effects of climate change on the efficiency of water trading, through developing a water trading model and afterward designing an index capable of considering the random feature of water availability in the condition of tradable water rights. In order to maximize the net benefit of the water system, the index has been measured with a stochastic programming.
    The effects of climate change on the water trading system were determined by comparing the index values between current climatic and future climate scenarios. Trading efficiency in a water trading system is strongly scenario-dependent. On the other hand it is expected that under water scarcity conditions water trading is an appropriate method for adaptation to the climate change effects
