| Zusammenfassung |
| National water use accounts are generally limited to statistics on water
withdrawals in the different sectors of economy. They are restricted to
"blue water accounts" related to production, thus excluding (a) "green" and
"grey water accounts", (b) accounts of internal and international virtual
water flows and (c) water accounts related to consumption. This paper shows
how national water-use accounts can be extended through an example for
Indonesia. The study quantifies interprovincial virtual water flows related
to trade in crop products and assesses the green, blue and grey water
footprint related to the consumption of crop products per Indonesian
province. The study shows that the average water footprint in Indonesia
insofar related to consumption of crop products is 1131 m3/cap/yr, but
provincial water footprints vary between 859 and 1895 m3/cap/yr. Java,
the most water-scarce island, has a net virtual water import and the most
significant external water footprint. This large external water footprint is
relieving the water scarcity on this island. Trade will remain necessary to
supply food to the most densely populated areas where water scarcity is
highest (Java). |
