On July 16th Prime Minister’s Office announced that it has formed a committee to study how private investment can be attracted to improve infrastructure in the inland waterways, which are emerging as cost effective transport routes along some of the important industrial corridors.
India is trying to improve their share in national transport.
“In several countries, IWT accounts for a substantial share as a percentage of the total: 32 per cent in Bangladesh, 20 in Germany, 14 in the U.S. and 9 in China. In China, much of the increase has occurred in recent decades, in tandem with its phenomenal industrial-agricultural growth. By contrast, in India only 0.15 per cent of domestic surface transport is accounted for by IWT, compared with 68 per cent for road and 30 per cent for rail.” – (The Hindu)
