Effect of Water Market Development and Improvement of Irrigation Technology on Farmers' Cropping Pattern and Income (Hashtgerd Plain, Alborz Province)

Creating water market as an economic solution on one hand, and simultaneously using modern irrigation techniques as a technical solution, in addition to adapting to the existing dehydration conditions, can optimize the pattern of farming and sale of water saved in the market and ultimately lead to increased farm income Gets The results showed that due to the launch of the water market in the region and the increase in the price of irrigation water from 10 to 100 percent, the level of all of the Hashtgerd plain is lower than the base year, and the changes in the pattern of cultivation after the simulation The acceptance of Hashtgerd plain farmers is different in applying the water price increase scenarios for different products. Also, despite the water market and the increase in the price of irrigation water from 10 to 100 percent, it reduces water consumption in the fields of selected products of Hashtgerd plain. By increasing the price of irrigation water, the volume of water consumed for all products of the pattern decreases. The results showed that, following the launch of the water market and rising water prices, at levels of this increase, farmers are moving toward improving irrigation technology and reducing their yields and incomes. However, to some extent, rising water prices, improving irrigation technology with considering the high cost of investing in such systems, they will not justify them, and in this area they resist the change in irrigation system and do the traditional irrigation, but in the range of rising water prices, the tendency towards changing the irrigation method is more modern and the traditional irrigation decreases. The limited water resources will not increase. Overall, the results showed that the effect of the increase in water prices in the conditions of the launch of the water market in 7 scenarios(10,20,30,40,60,80 and 100%), as well as the effect of improving the technology of irrigation method in two scenarios (20% of new methods And 80% of the traditional irrigation method (40% of the new methods and 60% of the traditional irrigation method), and after a combined assessment in 56 states, at best, an increase of revenue of 194.14 million rials will be achieved in the region.
