Disentangling the relations between human migrations and water resources is relevant for food security and trade policy in water-scarce countries. It is commonly believed that human migrations are beneficial to the water endowments of origin countries for reducing the pressure on local resources. We show here that such belief is over-simplistic. We reframe the problem by considering the interna...

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...

China is facing a water resources crisis with growing concerns as to the reliable supply of water for agricultural, industrial and domestic needs. High inter-annual rainfall variability and increasing consumptive use across the country exacerbates the situation further and is a constraint on future development. For water sustainability, it is necessary to examine the differences in water demand...

Traded agricultural goods redistribute water, virtually, around the world to satisfy unmet demands while limiting excess water extraction in importing regions. However, gaps remain our understanding of how alternative international trade regimes may alter demands, locally and virtually. Here, we explore global savings virtual impacts such under reference low-carbon scenarios using an integrated...
