“…By exploring the impact of multiple factors, such as embedded water, population, GDP, geographical distance, arable land, and dietary demand, the main drivers of virtual water flow appear to be GDP, population, and geographical distance with a nonnegligible effect of exporter production (Tamea et al, ). Subsequent work has leveraged this information to explore both link and flux predictions, population, geographical distance, and GDP strongly controlling link activation and the fluxes along those links (Tuninetti et al, ). Econometric analyses have been used to investigate the extent to which water is a source of comparative advantage (Debaere et al, ), in addition to the classic factors (i.e., labor, capital, and land, Wichelns, , ) typically considered by international trade theories.…”

Water availability is a major factor constraining humanity's ability to meet the future food and energy needs of a growing and increasingly affluent human population. Water plays an important role in the production of energy, including renewable energy sources and the extraction of unconventional fossil fuels that are expected to become important players in future energy security. The emergent competition for water between the food and energy systems is increasingly recognized in the concept of the “food‐energy‐water nexus.” The nexus between food and water is made even more complex by the globalization of agriculture and rapid growth in food trade, which results in a massive virtual transfer of water among regions and plays an important role in the food and water security of some regions. This review explores multiple components of the food‐energy‐water nexus and highlights possible approaches that could be used to meet food and energy security with the limited renewable water resources of the planet. Despite clear tensions inherent in meeting the growing and changing demand for food and energy in the 21st century, the inherent linkages among food, water, and energy systems can offer an opportunity for synergistic strategies aimed at resilient food, water, and energy security, such as the circular economy.

“…These trading communities evolve over time, and many trade links are created and dissolved every year (Carr et al, ). Due to the strong effect of trade community structures and on the trade‐offs associated with virtual water, a number of studies attempt to identify the factors driving the structure of the trade network (e.g., Dalin, Suweis, et al, ; D'Odorico et al, ; Fracasso, ; Konar et al, ; Sartori et al, ; Suweis et al, ; Tamea et al, ; Tuninetti et al, ). Yet identification of primary drivers is challenging because variables that represent central features of a virtual water trade system, such as GDP or population, may be simultaneously a determinant and an outcome of trade (see section for a discussion of causal relationships).…”

Because human and environmental systems in the Anthropocene are increasingly coupled, hydrologists and economists often find themselves studying the same systems from different vantage points. Here we argue that synthesis across economics and hydrology can help address two pressing sociohydrologic challenges: actionable prediction and the generation of transferable knowledge from place‐based studies. Specifically, we review (1) empirical methods and (2) theoretical approaches from economics and connect the two through a proposed iterative framework. First, we find that empirical methods for statistical analysis of natural and quasi‐experiments in economics can be leveraged to distinguish causal relations from mere correlations in complex and data scarce systems, which can help address the challenge of sociohydrologic prediction. Second, we find that economic theories based on rational choice can be used to decipher known paradoxes in water resources, which can help address the challenge of sociohydrologic knowledge generation. In both empirical and theoretical domains, specialized knowledge in hydrology remains critical to properly applying techniques from economics to coupled human‐water systems. We propose that linkages between the two fields highlight a large potential for interaction.

“…In recent years, the virtual water network related to internationally traded food commodities has been investigated to disclose its temporal patterns and dynamics (Carr et al, ; Dalin et al, ; Tuninetti et al, ), and it has been recognized that virtual water trade is mainly driven by socioeconomic factors rather than water resources availability (D'Odorico et al, ; Tamea et al, ; Yang & Zehnder, ; Zhao et al, ). A large number of outsourcing patterns of water consumption has been linked to the unsustainable use of freshwater resources worldwide (Dalin et al, ; Lenzen et al, ; Marston et al, ).…”

The recent intensification of international trade has led to a growing disconnection between consumer demand for goods and services and the water resources that support them. The important role of household demands on the exploitation of distant freshwater resources is widely recognized, yet the different socioeconomic drivers underlying the trends in domestic and foreign water use remain poorly quantified. In this work, the main mechanisms governing the exploitation of domestic and foreign freshwater resources are quantified by undertaking a structural decomposition analysis over the period 1994–2010 in 186 countries. Our results show that growth in affluence has been the main determinant of rising water consumption trends worldwide. There are indications that consumers in developed countries tend to increase their affluence by intensifying the use of foreign water resources. Conversely, affluence growth in developing regions seems to rely on the exploitation of local water resources revealing a significant imbalance among economies. The growth of affluence and population has been only partially offset by improvements in the intensity of blue water use by producers and, to a lesser extent, by changes in the interdependences among sectors.
