Abstract:
Rivers, marshy lands are the main features of our country, Bangladesh.
Many a number of rivers are prevailing in the country like intestine.
Bangladesh cannot be imagined except the rivers. The poets, littérateurs
wrote their works hailing the wetlands, rivers etc. Poet Rabindranath Tagore
once told that he who did not see Bangladesh by sailing boats on Padma had
not seen this country. He pointed out the mindset of Bengali people in the
early decades by his Nirjhorer Shapnabhanga and same as Padma
Mayamoyi by poet Jasimuddin. So, to understand Bangladesh the overall
conception should been about the rivers here in this country.
The physiological structure of Bangladesh is consisted of the silted soil
washed out from the river stream. The piling of the silted soil has made our
country like a deltaic shape in fact. As a result, the Bangladesh has huge
amount of fertile land which is responsible for high yielding of crops.
Today, our country has achieved the food sufficiency from food dependency
only by frequent grace of the land and soil. At the era of Emperor Jahangir
Bangla was marked as Jannnatabad (land of Heaven).
It is, however, easily perceived that the lifeline of Bengali people and
Bangladesh’s economy lies in rivers. In accordance of the condition and
location of the rivers, the intellects of Bengali people has based on the very
rivers from the historical period. The rivers were counted in the early period
as the water-highway. By using this river rout once (early British era) the
economy of Bengal was dominant in the global market.
The mercantile Europeans such as British, Portuguese, Dutch, and French
etc established their commercial hub near the riverside area. The old Dhaka
which is eminent for its Muslin fabrics was the gift of Bruiganga,
Shitalakhya, Balu etc. The district of Narayanganj, dubbed as the Dandy of
the East, was the port city for the marine ships carrying the goods from here
to Yorkshire, Dandy, and Hampshire etc where the industrial capitalism
took place in the early 18th century. This is why I would like to make clear
that although these rivers are locally flowing but had contributed the
economy globally.
I have conducted an M.Phil research work surveying the Shitalakya river.
This river now becomes very lean and thin due to the huge grabbing of its
land, polluting its sweet water and causing the threat of extinction of aquatic
life. Once, the river was the lifeline for socio-economic development of this
area while it has now become the dumping lake of industrial toxic and
chemical wastage. I have attempted to address the fault line behind the issue
in my research with some of inevitable limitations.
Mainly human created actions are liable to this consequence of rivers. In
this point Burigonga is the eminent example for me. The river Shitalakhya is
going to be another case of consequence like Burigonga. Many kinds of
threat are proactive on the Shitalakhya River. Among of these, illegal
dredging, capturing bank of river, throw dust into river from mill-factories
etc. This kinds of activities are exercised with money, mussle and political
power of some people.
The Sitalakhya River flows from west of Narayanganj District leading to the
Dhaleshwari River, which flows into the Meghna River at Bandar. The
Buriganga-Turag river system provides an important riverine link with the
Dhaka Metropolitan City. Other peripheral rivers such as Balu, Lakhya and
Tongikhal are also important in maintaining circular water route and natural
environment of the city. Waterways this are vital productive resources for
cities, regions and the country. The Shitalakhya provide amenities and
services to communities that are taken for granted. Drinking water, food,
transportation, communication, recreation, wildlife habitat, aesthetic appeal
of places along waterways, economic development, etc. are some of the
amenities that rivers provide.
I have conducted field surveys and secondary data collection to clarify the
relationships between domestic waste water discharge and pollutant load in
the river Shitalakhya. Besides this thesis developed can provide a guideline
to the future researchers about change of water quality, pollution, and sand
and land grabbers, setting mills-industry on the bank of Shitalakhya etc.
