The imbalance between water supply and demand in the country has challenged water resource management, especially in the agricultural sector. The virtual water study approach, as an approach that values the use of water inputs in the production and consumption of various commodities, has been established and discussed for almost two decades. Based on this concept, the issue of virtual water tra...

Since virtual education has been considered as an alternative for conventional education and it is in progress in M.
