INGENIEUR Shrinking green field due to urbanization and industrial use is one factor leading to water stress of that region. developed and determined to enable the introduction of virtual water as an instrument. Virtual water accounts should be developed to support national or regional water and agricultural policies. There is a real need for more research into the prescriptive potential of the virtual water theory and on the potential of virtual water trade to relieve pressure on the globe’s water resources and to achieve food security in the world’s water scarce regions. To make the concept of virtual water helpful in policy making, the concept itself needs to be further clarified and the difference with common food 6 30 trade must be more explicit. From the consumers’ perspective, there were suggestions that consumers should be informed of the virtual water content of the products they purchase from the market. Products label should mention water efficiency. Conclusion Malaysia with its abundance of rainfall will have a comparative advantage in virtual water trade for products and services when water stress around the globe reaches a dangerous threshold level due to population growth and shrinking green VOL 57 JANUARY-MARCH 2014 VOL 55 JUNE 2013 fields because of urbanization. However, the issue of pollution depending on the types of products selected has to be carefully examined. For example, aquaculture is considered to be a source of pollution in river systems especially for the fish rearing industry. The call for innovation in water efficiency will be a challenge to, and an opportunity for, the engineering fraternity. The introduction of water conservation in Green Building Index (GBI) certification is a good start but a better understanding of water footprints and virtual water should be inculcated in engineers at large.
