The effects of climate change on the income of Iranian farmers: DSSAT approach

According to the Global Risks Report, climate change was the fifth global risk in 2018 in terms of probability of occurrence. According to the same report, this phenomenon ranked second among other risks in terms of its effects on the world and the environment. It emphasizes the importance of investigating the effects of climate change. In this research, the economic analysis of the effects of climate change on the income of wheat farmers in the country during (2052-2022) has been done. DSSAT simulation program has been used to simulate the yield of irrigated wheat and economic analysis under climate change scenarios. The meteorological data required under different scenarios are taken from MarkSim software. The results show that the income of irrigated wheat farmers will decrease under climate change scenarios. Also, in some regions of Iran, irrigated wheat planting is dominant in conditions without climate change and under climate change scenarios, and it seems that these areas can be considered as favorable areas for creating irrigated wheat cultivation ports.
