ABSTRACT

Bangladesh is well known for its riverine network where the Inland Water Transportation is still considered as the major transportation sector. Around ten thousand of different types of registered vessels and thousands of unregistered vessels are plying in inland routes. This sector carries over 50% of cargo, 80% of fuel-oil and one quarter of all passenger traffic per year. Since long, traditionally river network has been regarded as safe and cost-effective route especially in the southern part of the country. Every year over 95 million passengers are carried through this route. Notwithstanding, a recent study by Asian Development Bank makes an indicative estimate of 332 million passengers in 2020-21. However, the fleet consists of 1061 Passenger vessels of different size and draft. This huge no of passenger vessels plying in inland routes made us vulnerable to significant marine pollution. The inland water ways are getting polluted by direct throwing of bilges, solid waste and oily water. Air pollution due to burning of engine oillub oil for running engines/ machineries is also contributing to marine pollution. In this paper, estimation of pollutants such as bilges, oily water and solid waste by inland passenger vessel operation has been made approximately. Amount of fuel burnt by inland passenger vessel operation has also been assessed. An environmental modelling has been done followed by the impacts of pollutants with the help of Eco Indicator 99 (I) of SimaPro. It has been revealed that there are considerable impacts of marine pollution on environment by inland passenger vessel operation and the major consequences such as climate change, destruction of fishing zone, respiratory problems of human being and rise of sea level. Few preventive measures have been suggested in this thesis work in the light of design modification, regulatory enforcement to reduce the marine pollutions.
