Transboundary Water Resources

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.

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.

Abstract. The Middle East and North Africa (MENA) region has the largest water deficit in the world. It also has the least food self-sufficiency. Increasing food imports and decreasing domestic food production can contribute to water savings and hence to increased water security. However, increased domestic food production is a better way to achieve food security, even if irrigation demands an increase in accordance with projected climate changes. Accordingly, the trade-off between food security and the savings of water and land through food trade is considered to be a significant factor for resource management, especially in the MENA region. Therefore, the aim of this study is to analyze the impact of food trade on food security and water–land savings in the MENA region. We concluded that the MENA region saved significant amounts of national water and land based on the import of four major crops, namely, barley, maize, rice, and wheat, within the period from 2000 to 2012, even if the food self-sufficiency is still at a low level. For example, Egypt imported 8.3 million t yr−1 of wheat that led to 7.5 billion m3 of irrigation water and 1.3 million ha of land savings. In addition, we estimated the virtual water trade (VWT) that refers to the trade of water embedded in food products and analyzed the structure of VWT in the MENA region using degree and eigenvector centralities. The study revealed that the MENA region focused more on increasing the volume of virtual water imported during the period 2006–2012, yet little attention was paid to the expansion of connections with country exporters based on the VWT network analysis.

Sustainable Water Use

Sustainable use of resources is critical, not only for people but for the whole planet. This is especially so for freshwater, which in many ways determines the food security and long-term development of nations. Here, we use virtual water trade to analyze the sustainability of water used by Pakistan in the international trade of 15 major agricultural commodities between 1990 and 2016 and in 2030. Most of the existing country-level studies on virtual water trade focused on net virtual water importers, which are usually water-scarce countries as well. This is the first study to concentrate on a water-stressed net virtual water-exporting country. Our results show that Pakistan has been trading large and ever-increasing volumes of virtual water through agricultural commodities. Despite the overall small net export of total virtual water per year, Pakistan has been a net-exporter of large quantities of blue (fresh) virtual water through its trade, even by fetching a lower value for each unit of blue water exported. Given Pakistan’s looming water scarcity, exporting large volumes of blue virtual water may constrain the country’s food security and long-term economic development. Improving water use efficiency for the current export commodities, for example, rice and exploring less water-intensive commodities, for example, fruits and vegetables, for export purposes can help Pakistan achieve sustainable water use in the future.

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.

Abstract. The aim of this study is to analyze the impacts of food trade on food security and water-land savings in the Arab World in terms of virtual water trade (VWT). We estimated the total volume of virtual water imported for four major crops – barley, maize, rice, and wheat – from 2000 to 2012, and assessed their impacts on water and land savings, and food security. The largest volume of virtual water was imported by Egypt (19.9 billion m3/year), followed by Saudi Arabia (13.0 billion m3/year). Accordingly, Egypt would save 13.1 billion m3 in irrigation water and 2.1 million ha of crop area through importing crops. In addition, connectivity and influence of each country in the VWT network was analyzed using degree and eigenvector centralities. The study revealed that the Arab World focused more on increasing the volume of virtual water imported during the period 2006–2012 with little attention to the expansion of connections with country exporters, which is a vulnerable expansion. This study shed light on opportunities and risks associated with VWT and its role in food security and land management in the Arab World.
