International virtual water flows from agricultural and livestock products of India

摘要

Indirect trade of water (virtual water) through export of crop and livestock products may pose a risk to water resources in the exporting country. Management strategies can be framed by identifying the partner countries and the current status of water resources in these countries. This study for the first time analyses the virtual water trade of India considering the specific virtual water contents of crop and livestock products from all partner countries from 1986 to 2013 (28 years). Average virtual water export of India is 59 Bm(3)/y and virtual water import is 32.6 Bm(3)/y. Net virtual water import (-26.4 Bm(3)/y) indicates India is a major exporter. Oil, cereals, industrial products (cotton, jute, hides etc.) and semi luxury goods contribute to 79% of virtual water export. Oil and nuts contribute to 71% of virtual water import. Decline in virtual water trade due to slow economic growth and impact of floods are reflected in the inter-annual variation. Highest virtual water trade from India is to countries in Asia (74% as virtual water export and 59% as virtual water import). Virtual water import to India are mainly through palm oil, cashew nuts, soybean, sunflower oil, wheat, rubber, cotton and pulses. Water footprint of India has increased by 1.3 times in 28 years. Strategies for sustainable management of water resources in India and the partner countries should aim at reducing the import of water-intensive goods from water-scarce countries and increasing import of water-intensive goods from water-abundant countries.
