Virtual water trade refers to the implicit content of water in the production of goods and services. When trade is undertaken, there is an implicit exchange of water. Furthermore, when water gets scarce, water intensive goods become more expensive to produce and the economy compensates through...

A virtuális vízszemléletre épülő vízkészlet-gazdálkodási döntésekhez szükséges minimális információk egy ország szintjén a következők (Európai Regionális Jelen¬tés, 2009): hol, mikor, mekkora és milyen minőségű hasznosítható vízkészlet áll rendelkezésre,...

Néhány évtizeddel ezelőtt a vidék és a mezőgazdaság fő feladata az volt, hogy elegendő mennyiségű és megfelelő minőségű élelmiszert és ipari alapanyagot állítson elő, hatékonyan foglalkoztatva a vidéki népesség jelentős hányadát. Később felmerült, hogy...

A recent trend of literature investigates how international trade compensates or accentuates the differences in countries’ endowments in water resources and whether trade regulation should be used to improve the use of water resources at the global level. We develop a simple model establishing...

The main idea of this paper is to analyse the relationships between the productive process and the commercial trade with water resources used by them. For that, the first goal is to find out, by means of the estimation of virtual water, the exported crops which have the highest water...

Andalusian agricultural sectors are relatively small, but consume by 90% of the available water resources. More than 50% of the final demands for agricultural products are exported to other Spanish regions or abroad. Using a virtual water concept with an input-output framework, we find that a...

Virtual water and water footprints have gained recognition as indicators to guide action on issues related to water scarcity. I argue that water footprints are fundamentally different from carbon footprints, as local reductions in carbon emissions have global benefits, while global attempts to...

Increasing freshwater demands have made allocation of water in water-scarce regions especially severe in arid areas. To assist in allocating water, a virtual water assessment methodology is described to assess strategies of saving water by identifying products which would be better as imports...

Without subdividing into blue and green virtual water, the virtual crop water is currently used in the allocation of water resources based on virtual water strategy. In order to improve agricultural water use efficiency and the proportion of green water utilization, a multi-objective optimal...
