Abstract
This research aimed to evaluate water footprint and irrigation dietary efficiency (IDE) of potato production in the Ghorveh-Dehgolan Plain of Kurdistan Province, during 2011and 2021. In this study, water footprint indices (blue, green, and grey), net production benefit per drop (NPBD), and irrigation dietary efficiency (IDE) were calculated using data from the Agricultural Jihad Organization, Meteorological Organization, FAO, and the USDA Food Composition Database. The results indicate that the average total water footprint for each ton of potatoes in the Ghorveh and Dehgolan regions was 431 and 446 cubic meters, respectively; i.e. producing each ton of the product requires significant consumption of water, which indicates high pressure on the region's limited water resources. Additionally, the economic productivity of water in Ghorveh (388 Tomans/m3) is higher than in Dehgolan (372 Tomans/m3). Analysis of dietary indices also showed that each liter of water in Ghorveh produces an average of 5.95 k.cal. and 0.016 g of protein, while these values in Dehgolan are 5.73 k.cal. and 0.014 g, respectively. Furthermore, examining the temporal trend of indices reveals a significant decrease in productivity during drought years, highlighting the vulnerability of the region's agricultural system to climate change. This research emphasizes the necessity of a paradigm shift from the approach of "supplying more water" toward "more efficient management of existing water" and, by providing evidence based on field data, establishes an appropriate scientific foundation for water resource and agricultural policy-making in critical regions of the country.
