Abstract

Water scarcity has made water management one of the top priorities in the world because of climate change and population growth on the one hand and increasing demand for food on the other. The present study aimed to simulate the effects of conservation policies on water resources in the Dashtab plain, Iran, using the positive mathematical programming (PMP) method. Data were collected by a questionnaire for which 136 questionnaires were filled by randomly sampled experts of Agricultural Jihad Organization. The results showed that out of the three policies adopted in this study including limiting irrigation inputs, reducing irrigation input subsidies, and reducing crop prices, reducing subsidies on irrigation inputs were the best policy to protect irrigation resources and farmers' incomes.

Highlights

  • The results showed that the two crops of barley and wheat were removed from the cultivation pattern due to high water consumption and crop price.
  • Millet product is more suitable for the cultivation pattern of the region than other products due to its favorable price and low water consumption.
  • In this research, a positive planning applied model was used to optimize water consumption and cultivation pattern in the region.
  • For optimal water consumption, scenarios of reducing water subsidies, restriction water resources and reducing the price of products were used.
