Abstract: Rapid population growth and climate change are poised to significantly impact water resources and agriculture. Consequently, it becomes imperative to delve into the repercussions of climate change on agriculture and natural resources in developing nations. In this research, an economic–hydrological model was employed to assess the influence of climate change on water management and cropping patterns in the Eastern border catchment of Iran. The climatic data used in this study, spanning the years 1997–2022, encompassed daily rainfall and temperature records from the Khorasan and Sistan & Balouchestan meteorological organization, as well as the Iranian Statistical Center. Monthly water discharge data were obtained from the Khorasan and Sistan & Balouchestan regional water authority, while information on crop levels and agricultural inputs was collected from the Khorasan and Sistan & Balouchestan agricultural jihad organization. The findings reveal that areas dedicated to cultivating high-yield crops experienced a decrease when associated with high water consumption, whereas the cultivation areas of high-yield crops expanded when water consumption was reduced. The implementation of modern irrigation methods, such as pressurized irrigation, not only conserves valuable water resources but also enhances efficiency, ultimately resulting in decreased water consumption and increased production. Consequently, the provision of enhanced training programs aimed at educating farmers about these practices and facilitating their adoption can play a pivotal role in adapting to and mitigating the challenges posed by climate change.
