Survey of Virtual Water Trade and its Impact on Water Productivity in the Shoshtar MianAb irrigation and Drainage Network

Water is the first and foremost limiting factor for agricultural production, and undoubtedly, water crisis is considered as one of the international challenges for governments and human societies. Given that virtual water was first used as a way to tackle water scarcity in countries with limited water resources, so that countries with low water should import food from abundant countries...

Determination of optimal and and water allocation under limited water resources using soil water balance in Ordibehesht canal of Doroodzan water district

ABSTRACT- Inadequate water supply is the major problem for agriculture in arid and semi-arid regions. Thus, effective management should be considered for water resources planning. In this research, a model was provided which is able to estimate optimal land and water allocation in the Doroodzan irrigation network. Optimal water management model was used at farm level to evaluate different defic...

Water Resources Management by Simulation under Virtual Water Scenario in Agricultural Sector, Case Study: Hirmand Catchment, Iran

Due to the frequent drought periods, water consumption increase, and competition of different water-using sectors, the Hirmand catchment is in a critical water status in the Sistan region. This threat has been intensified in recent years. To cope with this problem, we must pay more attention to different types of water use such as virtual water as a water saving method. The present study calcul...

Irrigation Water Pricing in Iran: The Gap between Theory and Practice

Pricing policies play an important role in water demand management and its optimal allocation. Determining proper water price leads to optimal allocation of water especially in agricultural consumptions. Applying new subsidy targeting law in Iran which insists on pricing water based on its supply cost, will effects considerably on water resource management in agriculture sector. So, in this stu...

Experimental Study of Phase Inversion in n-Butylacetate-Water, Kerosene-Water, and n-Heptane-Water Systems in a Rotating Disc Contactor Column

The Relationship between Virtual Water Exports and the Country’s Water Resources Inventory

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...
