Efficiency must be increased
In Iran's South Khorasan province, an important barberry-growing region, irrigation is increasingly becoming a challenge. Over the last 50 years, rainfall here has decreased by 25%, and with climate change, there is an urgent need to increase irrigation efficiency and introduce new irrigation methods. Producers are particularly pushing for the construction and further development of irrigation canals there to boost production. In addition, irrigation networks need to be expanded and new ways of storing water reserves need to be created.
