| Zusammenfassung |
| Climate change, economic development, and population growth are bound to increasingly
impact global water resources, posing a significant threat to the sustainable development of
arid regions, where water consumption highly exceeds the natural carrying capacity,
population growth rate is high, and climate variability is going to impact both water
consumption and availability. Virtual Water Trade (VWT) — i.e. the international trade
network of water-intensive products — has been proposed as a possible solution to optimize
the allocation of water resources on the global scale. By increasing food availability and
lowering food prices it may in fact help the rapid development of water-scarce
regions. The structure of the VWT network has been analyzed by a number of authors
both in connection with trade policies, socioeconomic constrains and agricultural
efficiency.
However a systematic analysis of the structure and the dynamics of the VWT network
conditional to aridity, climatic forcing and energy availability, is still missing. Our goal is
hence to analyze the role of arid and hyper-arid regions within the VWN under diverse
climatic, demographic, and energy constraints with an aim to contribute to the ongoing
Energy-Water-Food nexus discussion. In particular, we focus on the hyper-arid lands of the
Arabian Peninsula, the role they play in the global network and the assessment of their
specific criticalities, as reflected in the VWN resilience. |
