In the dry regions of the Caucasus, water from the numerous rivers is diverted to irrigate arid lands, particularly in eastern Ciscaucasia, the Kura-Aras Lowland, and areas surrounding the Middle Aras Trough.1

This irrigation is essential for supporting the production of crops such as cotton, rice, and alfalfa (lucerne). Additionally, mulberry trees are commonly planted along the banks of irrigation canals, providing the necessary foundation for silkworm culture and the local silk-making industry. These water management practices allow for productive agriculture in areas that would otherwise be too dry for such cultivation.21
