a huge part of the Karatoa
River at several spot had
been occupied by land grabbers in Bogra and Gaibandha dristict in Rajshahi
claimed by Bangladesh Water Development (WDB) Board and the Department of
Powerful people of those are have
occupied large areas of land on both sides of the river in the two districts. Their
aims of those people are build multi-storey buildings there. The environment
department identified grasped river land where some people including Non
Government Organizations (NGO) even included Thangamara Mohila Shabuj Shango
and Diabetic Hospital in Bogra.
WDB Bogra district Sub-Assistant
Engineer AKM Najmul Hassain said that already has been occupied for farming and
other purposes by encroachers about 57 kilometres of the 86.75 kilometres
channel from Khalisha to Khanpur.
The river lost Khalisha in
Gaibandha to Khanpur channel in Bogra which is considering as main channel of
the river before about 23 years ago, said WDB officials.
To run water flow of the river, WDB
in Khalisha area constructed a three-vent control device in 1989. Farmers on
both riverbanks started cultivation of Boro (One kind of crop) and other kinds
of seasonal crops from Khalisha to Khanpur from the beginning of the winter period.
The environment department has
been taken an initiative to restore flow of the river from Khalisha of
Gobindaganj upazila in Gaibandha to Khanpur of Sherpur upazila in Bogra
district. WDB sources said that the department prepares to make gabbers’ list
to expel them and restore the river channel.
M Inamul Haque mentioned in his
book ‘Water Resources Management in Bangladesh’ that from the Rennell’s Map of
1779 it come into sights that the Karatoa began from the foothills of the
Himalayas in Darjeeling of West Bengal (India) and joined the Atrai river in
According to the DoE Bogra officials, the river is dangerously
polluted by chemical, household and industrial waste presently.
Already majority part of The
Teesta River has dried up due to extreme fall in water levels in summer season.
It’s fall due to a barrage in India,
upstream of the Teesta Irrigation Project at Dalia, Lalmonirhat. Experts think
that the barrage is the main hinder natural flow of the river.
Officials of Bangladesh Water Development Board (WDB) said cute to creating several sandy shoals on the river had been fall which effect hampers on agriculture, environment, communication, and livelihoods. At least 5,000 people at shoal villages in Sundarganj upazila, Rangpur are sufferer and a long area is desiccated in Rangpur.
Chandipur Union Parishad of the Upazila Golam Mostafa Ahmed chairman said to Bd Environment over phone that at least thousand people become unemployed. And they will be employed for a season for a lack of fertility due to vast tracts of land along the riverbank remains unplanted.
The locality and government are
neglected to be responsible for the relentless degradation. As source of
livelihood, communication, and heart of people in Dhaka had been determined to
the Buriganga River but now it’s a major source of
running the capital. This happens due to pollution and building illegal
property by robbering.
Along with Buriganga, Turag, Shitalakkhya,
Balu and Bangshi is being a death trap
for increasing pollution and also indiscriminate sand lifting. The minimal
level of dissolved oxygen (DO) required for life to survive in these rivers do
Researchers of The Department of
Environment (DoE) had been an alarming message on levels of DO in these rivers
after three months research. They have analysis on various samples of chemical
whose were collected from these rivers
and the levels of DO in Buriganga, Turag and Bangshi were 0.38, 0.59 and
0.0 milligram per liter gradually.
According to the Environment
Protection Act (Amendment) 2010, the minimum required level DO is 5 mg/l for
any water body to sustain aquatic species including fishes and others is. The
minimal standard rate for water being eligible for treatment as drinking water
is 6 mg/l.
Contacted with Environment Erpert
Dr Ahsan Uddin Ahmed over phone, he said to Bd Environment that “such a DO
merge amount in water poses severe a great threats to biodiversity and
hydro-ecology”. “Random dumping of waste has put the rivers in and around the
city in a blackout”.
Professor Mujibur Rahman of Bangladesh
University of Engineering and Technology (Buet) said that government ought to
shift the tannery diligence from the Hazaribagh, Dhaka.
The chemical waste from the tanneries is a major polluter of these rivers.
It’s important that The DoE research had been found
that the level of DO at the Hazaribagh area of Buriganga River
was 1.06, 0.50 and 1.0 mg/l in January, February and March gradually. And the
Bio-Chemical Oxygen Demand (BOD) is also very high in these waters.
