Virtual Water Trade

The sustainable and efficient use of water resources has gained wide social concern, and the key point is to investigate the virtual water trade of the water-scarcity region and optimize water resources allocation. In this paper, we apply a multi-regional input-output model to analyze patterns and the spillover risks of the interprovincial virtual water trade in the Yellow River Economic Belt, China. The results show that: (1) The agriculture and supply sector as well as electricity and hot water production own the largest total water use coefficient, being high-risk water use sectors in the Yellow River Economic Belt. These two sectors also play a major role in the inflow and outflow of virtual water; (2) The overall situation of the Yellow River Economic Belt is virtual water inflow, but the pattern of virtual water trade between eastern and western provinces is quite different. Shandong, Henan, Shaanxi, and Inner Mongolia belong to the virtual water net inflow area, while the virtual water net outflow regions are concentrated in Shanxi, Gansu, Xinjiang, Ningxia, and Qinghai; (3) Due to higher water resource stress, Shandong and Shanxi suffer a higher cumulative risk through virtual water trade. Also, Shandong, Henan, and Inner Mongolia have a higher spillover risk to other provinces in the Yellow River Economic Belt.

Game Analysis

As the global water resource is becoming more and more serious,a new way of solving the water resources problems with the idea of virtual water trade gains attention gradually.Using the prisoner’s dilemma in game theory model,analyzes the water resource game and international trade respectively.Combines the water resource and its security with the international trade,then build the game model of virtual water trade.Through analysis of these three games,find the water resources and the international trade game have equilibrium differences and complementarities returns,the implementation of virtual water trade will make both parties achieve even greater gains in terms of cooperation, increasing the possibility of breaking the prisoner's dilemma. Therefore,combine the water resources with the international trade will ensure a country’s water security in a larger extent and avoid producing high transfer cost and ecological destruction.

The Impact

Declining water resources and increasing demand of water for agricultural, industrial, and domestic sector and potential climate change has posed a major challenge to maintain water sustainability of a nation. There is a need to adopt long-term perspective for assessment and policy design for sustainability of primary resources like water. It is also argued that virtual water trade has raised issues of water sustainability as even small but continuous net virtual water trade may influence the water sustainability through irreversible losses. With the constraints for water sustainability, virtual water trade has received much attention in the recent years. While the impact of virtual water trade on water sustainability of virtual water exporter country is less explored and assessed. India is a major water exporting country resulted tremendous pressure on water resources that has serious threat to food security and the negative impact on development of economy and other sectors.

The Impact

The linkages between agricultural trade and water resources need to be identified and analyzed to better understand the potential impacts that a full liberalization, or lack thereof, will have on water resources. This paper examines trade of virtual water embodied in agricultural products for most countries of the world. The main purpose of the paper, however, is to examine the impact of trade liberalization on virtual-water trade in the future. Based on a simulation of global agricultural trade, a scenario of full liberalization of agriculture was used to assess the net effect of virtual water flows from the relocation of meat and cereals’ trade. The paper also identifies the main reasons behind the changes in the magnitude and direction of the net virtual water trade over time, and shows that virtual water trade flows are independent of water resource endowments, contrary to what the Heckscher-Ohlin Theorem states. Finally, based on a formal model, some input demand functions at the country level are estimated. The estimates of the income and agricultural support elasticities of demand for import of virtual water have the expected sign, and are statistically significant. Variables found to have some explanatory power of the variance of virtual water imports are average income; population; agriculture as value added; irrigated area, and exports of goods and services.

Abstract Limited and declining water resources, increasing demand of water resources from different sectors has posed a major challenge for maintaining water sustainability and thus overall sustainability for a populous and water scarce country like India. Over extraction and changing climate have put additional pressure to maintain water sustainability. Therefore, there is a need of proper planning of utilization and management of water resource. Recently, virtual water trade has received much attention and become important tool for balancing the water budget. On the other hand, virtual water trade may also adversely effects on water balance of exporter's country as well as economy. Analysis of virtual water trade with its implications on water resources are missing, hence, there is a need of such analysis that will help in management of water resources. In this study an attempt is made to present a quantitative analysis of virtual water trade and its implications on water sustainability. For this study rice crop is considered only due to its characteristics as rice is major water consumer crop and water exporter crop from India.

Virtual water trade (VWT) is a powerful concept which stimulates fresh thinking about water scarcity and management. It is a potential solution for water-short countries to achieve food security. VWT may also have the potential to play a key role in international negotiations over management of transboundary water resources.
