With land scarce and the floating population high, Goa needs to ensure that its logistic systems are placed correctly. The State has plenty of rivers which can be used as inland waterways. It is economic too. According to the Inland Waterways Authority of India (IWAI), operational cost per tonne per kilometre through inland waterways is Rs 1.06 as compared to Rs 1.41 by rail and Rs 2.28 by road. The total cost of inland navigation, after accounting for accidents, congestion, noise, emissions, air pollution and other environmental impacts is estimated to be one-seventh of that of road transport.
