Socio-economic Status and Environmental Issues of
Kaptai, Rangamati.
The goals of the Bachelor of Environmental Science Degree are to: Offer a rigorous science-based
preparation for careers in environmental science; Prepare students for graduate studies in
environmental science. Environmental Sciences is a kind of subject where only theoretical lessons
cannot provide hundred percent of knowledge. The earth is a mysterious planet and to gain
knowledge about the earth, visual observation through tour is must. Environmental science is the
scientific investigation of human interactions with natural systems. The department of
environmental sciences of Jahangirnagar University runs a course on field work as an academic
study course each year. For the students of Environmental Sciences, field work is a part and parcel
of academic study. It plays a very significant role in understanding complicated environmental
concepts and their impact on biodiversity and sustainability. To evaluate the natural and artificial
processes of the study areas and finding it’s role on environment. As a student of 3rd year of
environmental sciences of Jahangirnagar University in the session 2011-2012 carried out a field
work for 4 days from 14th November 2015 to 18th November 2015 at Kaptai, Rangamati. Kaptai
has enormous geological and biological resources to identify, understand and need to protect from
anthropogenic and non-anthropogenic threats. It needs more study to gather knowledge about these
beautiful sites.
Acknowledgement
Practical implementation of analyzed knowledge is very important for developing the
problem solving ability of a student. Environmental science, like all other brunches of science
requires a proper practical knowledge and ability to implement knowledge in environment to
minimize possible adverse environmental degradation and maximizing possible beneficial
events. If an environmental scientist doesn’t have a good knowledge about problems and
possibilities in implementing environmental knowledge, he/she will have to suffer a lot. By
realizing this fact, the department of environmental sciences of Jahangirnagar University runs
a course on field work as an academic study course each year. As a student of B.sc (hons) 3rd
year, we went on a field trip in Rangamati and Kaptai region.
First and foremost I offer my deepest gratitude and I’m cordially grateful to my almighty
Allah and may His peace and blessings be upon all his prophets for granting me the chance
and the ability to successfully complete this field tour in Rangamati region.
It is a matter of great pleasure for me to thank from the core of the heart to my honorable
teacher A H M Saadat, Associate Professor, Department of Environmental Sciences,
Jahangirnagar University. I want to give special and heartiest thanks and also acknowledge
the excellent support from my honorable sir Mirza A.T.M. Tanvir Rahman, Assistant

1.1 Background of Study Tour
Due to the Environmental significance of Chandraghona, Rangunia, Kaptai & Rangamati, we
have visited this area for our field tour this year.
Kaptai is an Upazila of Rangamati District in the Division of Chittagong, Bangladesh. Notable
landmarks are the Karnaphuli Hydroelectric Power Station, the only Hydro-electric power
plant of Bangladesh. The Kaptai Dam, built for this purpose on the Karnaphuli River, created
the Kaptai Lake, the largest man-made dam in Bangladesh.
Rangamati is the administrative headquarters of Rangamati Hill District in the Chittagong Hill
Tracts of Bangladesh. It is also a Capital city of Chittagong Hill Tracts. The town is located at
22°37'60N 92°12'0E and has an altitude of 14 metres (49 feet). The district is administered by
an office named as District Administration, Rangamati. From Chittagong a 77 km road leads
to Rangamati. The township is located on the western bank of the Kaptai Lake. Rangamati is a
holiday destination because of its landscape, scenic beauty, lake, colourful indigenus groups
(Chakma, Marma etc.), its flora and fauna, indigenous museum, hanging bridge etc.
1.2 Study Area Selection
Study area selection is a very important fact for a study tour. Because, which kind of knowledge
we want to learn, fully depends on the site of the tour. So I would like to thank our honorable
teachers because before starting our tour they selected our tour site. Our main site was
Rangamati Hill tracts district & adjacent area. The sites of this tour were-
Kaptai
Chandraghona
Rangunia
Rangamati

Socio-economic Status and Environmental Issues of Kaptai, Rangamati. By Abu Khairul Bashar
Rangamati is a district in South-eastern Bangladesh. It is a part of the Chittagong Division
and the town of Rangamati serves as the headquarters of the district. Area-wise, Rangamati is
the largest district of the country. Rangamati was a contesting ground for the kings of Tripura
and Arakan. This region came under the Mughal Empire after the Muslim invasion in 1566. In
1737 Sher Mosta Khan, a tribal leader, took refuge with the Mughals. After this the Chakma
settlement began along with various other settlements of varying ethnicity.[2] From 1760 to
1761, this land was leased to the East India Company.[2] The district of Rangamati consists of
10 upazilas, 1 municipality (9 wards and 35 mahallas), 50 union parishads, 162 mouzas and
1347 villages.

1.4 Limitations
The data sources of the study tour were basically based on secondary data sources. That’s why
in this tour there were some limitations-
Time was limited, so it was difficult to collect more information within these short time.
Limitation of budget
Different people gave different information so we were confused about actual
information.
Underground sites were not allowed for investigation due to risky conditions.
Time was not sufficient to investigate these two large projects.
Rainy weather hampered the total fieldwork.
For some technical problem it was restricted
We were 30 students, so it was difficult to move with this he number of people.

2.1 Methodology
Methodology is the systematic, theoretical analysis of the methods applied to a field of study,
or the theoretical analysis of the body of methods and principles associated with a branch of
knowledge. It, typically, encompasses concepts such as paradigm, theoretical model, phases
and quantitative or qualitative techniques. A methodology does not set out to provide solutions
but offers the theoretical underpinning for understanding which method, set of methods or so
called “best practices” can be applied to a specific case. Methodology does not describe specific
methods, even though much attention is given to the nature and kinds of processes to be
followed in a particular procedure or in attaining an objective. When proper to a study of
methodology, such processes constitute a constructive generic framework; thus they may be
broken down in sub-processes, combined, or their sequence changed.

2.2 Data Collection and Data Sources
Every work has some purposes and method of completing those purposes. After complete
purpose than need the processing of data which is collected from field. We know that data is a
body of information in numerical form and it is a collection of statistical information of values
of the variable of interest in a study. On the Basis of sources, data is two types. In this report
we use both type data. The sources of both data are given below-
2.2.1 Primary Data Sources
Primary data are obtained from the organization or institution that originally collected the
information. The data collected for the first time by the investigator as original data are known
as primary data. In this study tour we have collected the primary data by the following ways-
Visual observation: By visiting a particular place and after observe that we get some
data which is helping us to make a report.
Questionnaire: At first we select a particular place or particular topics, then to know
everything about that place all related question contain on a sheet of paper and in this
way be collect all types of information.
Discussion: Group discussion is a very important process of reporting. By this process
many view idea develops and those can help to make a successful report. According to
this process we collect all types of information.
Interview: By interview we can gather more different and much knowledge which help
us to collect information and data. In this study tour, we have got a seminar presentation
in tribal cultural institute of Cox’s Bazar. By this seminar we knew details about tribal,
lifestyle and other phenomena.

Map Reading: We came to know about the location and area of our traveling area from
map. We know the road to Cox’s bazaar from route map.
Photograph: We snapped various charming natural sceneries. These photographs
helped us in observation and research. They are also a great source of our enjoyment.
Literature Review: A comprehensive literature study was done to gain an exact
scenario of the two mine. Various important and necessary data are collected from
already published books, journal, previous works, newspaper, internet etc. By gathering
all the information the field report of our study tour is made. We come to know about
the previous condition of the area and can identified the difference with present
situation.
2.2.2 Secondary Data Sources
We know that if an investigator is using data which have been collected by someone else, then
such data are known as secondary data. For make a successful report we have followed some
secondary data sources such as:-
Different published Books
Banglapedia
Different Journals
Encyclopedia
From different organization
From related books

3.1 Plywood Industry
Plywood is a sheet material manufactured from thin layers or "plies" of wood veneer that are
glued together with adjacent layers having their wood grain rotated up to 90 degrees to one
another. It is an engineered wood from the family of manufactured boards which includes
medium-density fibreboard (MDF) and particle board (chipboard).
All plywoods bind resin and wood fibre sheets (cellulose cells are long, strong and thin) to
form a composite material. This alternation of the grain is called cross-graining and has several
important benefits: it reduces the tendency of wood to split when nailed at the edges; it reduces
expansion and shrinkage, providing improved dimensional stability; and it makes the strength
of the panel consistent across all directions. There are usually an odd number of plies, so that
the sheet is balanced—this reduces warping. Because plywood is bonded with grains running
against one another and with an odd number of composite parts, it is very hard to bend it
perpendicular to the grain direction of the surface ply.

3.1.1 Raw Materials
The outer layers of plywood are known respectively as the face and the back. The face is the
surface that is to be used or seen, while the back remains unused or hidden. The center layer is
known as the core. In plywoods with five or more plies, the inter-mediate layers are known as
the crossbands. Plywood may be made from hardwoods, softwoods, or a combination of the
two. Some common hardwoods include ash, maple, mahogany, oak, and teak. The most
common softwood used to make plywood in the United States is Douglas fir, although several
varieties of pine, cedar, spruce, and redwood are also used.
Composite plywood has a core made of particleboard or solid lumber pieces joined edge to
edge. It is finished with a plywood veneer face and back. Composite plywood is used where
very thick sheets are needed. The type of adhesive used to bond the layers of wood together
depends on the specific application for the finished plywood. Softwood plywood sheets
designed for installation on the exterior of a structure usually use a phenol-formaldehyde resin
as an adhesive because of its excellent strength and resistance to moisture. Softwood plywood
sheets designed for installation on the interior of a structure may use a blood protein or a
soybean protein adhesive, although most softwood interior sheets are now made with the same
phenol-formaldehyde resin used for exterior sheets. Hardwood plywood used for interior
applications and in the construction of furniture usually is made with a urea-formaldehyde
resin.
Some applications require plywood sheets that have a thin layer of plastic, metal, or resin-
impregnated paper or fabric bonded to either the face or back (or both) to give the outer surface
additional resistance to moisture and abrasion or to improve its paint-holding properties. Such
plywood is called overlaid plywood and is commonly used in the construction, transportation,
and agricultural industries. Other plywood sheets may be coated with a liquid stain to give the
surfaces a finished appearance, or may be treated with various chemicals to improve the
plywood's flame resistance or resistance to decay.

3.2.4 Rubber Sector
First attempt to grow Rubber in Bangladesh was made in 1952 when Forest department planted
some thousands of seed & budded stamps in chittagong imported from Malaysia & Srilanka.
In 1959 FAO expert investigated the possibilities of producing rubber in large scale &
recommended to cultivate Rubber extensively. In the year 1959 BFIDC (the then EPIDC) was
established by the then Govt. In 1962 Forest Department handed over Rubber Planting
Activities to BFIDC. Under an agreement signed between the Govt. of the then East Pakistan
(now Bangladesh) & EPIDC (now BFIDC) on 13-04-1963 & BFIDC was mandated to get
forest land on lease to raise Rubber Garden.
Figure-3.5: Rubber Plantation project of BFIDC
3.2.4.1 Positive Impact of Rubber Plantation
Rubber is a very useful crop preferred fast growing multi-purpose species for quick
afforestation.
Rubber plantation protect soil erosion and environment by carbon sequestration,
conserve water and nutrients and give good economic yield.
Rubber plant is capable of storing carbon in a higher rate in comparison to many other
tree species.
In Bangladesh, the rubber plantations can be a remarkable source of carbon trading.
Overall, rubber planting generates the highest economic and social benefits in terms of
profitability, employment, foreign exchange savings, land use and a positive
environmental impact

3.3 Karnaphuli Paper Mills
Karnaphuli Paper Mills is a Government-owned paper pulp and paper manufacturer is
Chittagong, Bangladesh. The factory is the largest paper producing factory in Bangladesh and
operates as a subsidiary of Bangladesh Chemical Industries Corporation. Karnaphuli Paper
Mills was the first paper manufacturing industrial establishment registered under the Factories
Act. At the time of its establishment, it was the biggest paper mill in Asia, with over 3,000
workers. It was established under a World Bank loan supported by a consortium of suppliers
from the United States, United Kingdom, Germany, Sweden and Italy. The factory went into
production in 1953 with an installed capacity of 30,000 tons of paper per year. The capacity
utilization, however, went down within a few years of its establishment. In 1964, Karnaphuli
Paper Mills was sold to the Dawood Group of Pakistan, which undertook a balancing,
modernization and rationalization program. Karnaphuli Paper Mills sold its paper to both East
and West Pakistan. The price of its paper was the same in both wings. As a result, users of
Karnaphuli Paper Mills paper in East Pakistan paid a price higher than its actual cost plus a
normal profit. They compensated for the cost of transportation of the paper to West Pakistan
and thus implicitly financed the subsidy enjoyed by its users in that province.

3.3.1 Raw Materials
The main source of wood fibre used in the manufacture of paper is harvested from scientifically
grown plantations of either hard, (gum), or softwoods, (pine) for conversion into a number of
varying grades of paper. No indigenous trees are used and the siting and planning of plantations
takes cognisance of the fact that they need to co-exist with the indigenous environment with
minimum impact. Fibre for papermaking is also sourced from sawmills in the form of wood
chips from off-cuts as well as from the recovery of used paper of all types. This “recycled fibre”
ensures that the cellulose content, carbon, remains in a form that postpones degradation, (and
hence carbon dioxide generation), for as long as possible. In addition to fibre, a number of
chemicals are used to convert the raw cellulose into a form that can be converted into the
plethora of paper grades required by the end user: Other materials used in the paper making
process are listed below:
Pulping chemicals consisting of sodium hydroxide, sodium sulphate, sodium carbonate
and calcium oxide are the main constituents. The bulk of these chemicals are recovered
in the recovery section of the pulp mill and re-used in the process.
23 | P a g e
Socio-economic Status and Environmental Issues of Kaptai, Rangamati. By Abu Khairul Bashar
Water – the bulk of the water is used in the paper making process to dilute cellulose
fibre to be formed on the paper machine. Virtually all this water is recovered and
recycled back to the machine
Paper making chemicals – such as starches, dyes, and strengthening and water proofing
agents – impart a number of different and important properties to the sheet of paper
being formed on the machine.
Figure-3.7: Raw materials of Karnaphuli paper mills
3.3.2 How Paper is made
Paper is simple material. It is essentially a mat held together by the fiber’s roughness, and can
be made from almost any fibrous material like wood or recycled paper. The process for making
paper was invented in China in the second century A.D., and all paper was made one sheet at
a time until 1798. To learn more about the history of paper. The process of making paper has
not changed – at least, fundamentally – since its discovery. But with almost two centuries of
improvements and refinements, modern papermaking is a fascinating, high tech

Figure-3.8: Paper Producing Flowchart
Step 1: Forestry
Typically, trees used for papermaking are specifically grown and harvested like a crop for that
purpose. To meet tomorrow's demand, forest products companies and private landowners in
Wisconsin plant millions of new seedlings every year.
Step 2: Debarking, Chipping and/or Recycling
To begin the process, logs are passed through a debarker, where the bark is removed, and
through chippers, where spinning blades cut the wood into 1" pieces. Those wood chips are
then pressure-cooked with a mixture of water and chemicals in a digester. Used paper is another
important source of paper fiber.

Step 3: Pulp Preparation
The pulp is washed, refined, cleaned and sometimes bleached, then turned to slush in the beater.
Color dyes, coatings and other additives are mixed in, and the pulp slush is pumped onto a
moving wire screen. Computerized sensors and state-of-the-art control equipment monitor each
stage of the process.
Step 4: Paper Formation
As the pulp travels down the screen, water is drained away and recycled. The resulting crude
paper sheet, or web, is squeezed between large rollers to remove most of the remaining water
and ensure smoothness and uniform thickness. The semidry web is then run through heated
dryer rollers to remove the remaining water. Papermakers carefully test for such things as
uniformity of color and surface, water resistance, and ink holding ability.
Step 5: Paper Finishing
The finished paper is then wound into large rolls, which can be 30 feet wide and weigh close
to 25 tons. A slitter cuts the paper into smaller, more manageable rolls, and the paper is ready
for use.. The largest papermaking machines are over 32 feet wide, 550 feet long and can
produce over 1,000 miles of paper a day.
3.3.3 Environmental Impacts of the Paper Industry
Contaminated Sediments
The paper industry has been a major source of accumulated toxic chemicals in several rivers in
Wisconsin, most notably of PCBs to the Fox River and Green Bay system in northeast
Wisconsin. As a result of recycling PCB-containing carbonless copy paper, area mill operations
discharged about 250,000 pounds of PCB’s contaminating Lower Fox River
sediment. According to the U.S. Environmental Protection Agency (EPA), an estimated
160,000 pounds of PCB’s have already left the river and entered Green Bay and Lake
Michigan. The EPA further estimates that on average, 300-500 additional pounds are flushed
from River sediment each year.
26 | P a g e
Socio-economic Status and Environmental Issues of Kaptai, Rangamati. By Abu Khairul Bashar
Continuing Toxic Pollution
The paper industry is a major source of toxic chemical pollution in Wisconsin. The federal and
state Toxic Release Inventories shows releases of approximately 14 million pounds of known
toxic substances in 1996. Modest reductions in chemical use over the years (per unit of
production) seem to be countered by increased production.
Many toxic chemicals are used in paper making, especially toxic solvents and chlorine
compounds used to bleach and delignify pulp. Additional toxins are used as biocides to prevent
bacterial growth in the pulp and finished paper products. (In the past, toxic mercury compounds
were used as biocides, contributing to Wisconsin's mercury contamination problems in fish.)
Conventional Air Pollution
Pulp and paper mills are large sources of standard air pollutants, such as carbon dioxide, nitrous
oxides, sulfur dioxides, carbon monoxides and particulates. These contribute to ozone
warnings, acid rain, global warming and respiratory problems. Many of the mills are large
enough to have their own coal-fired power plants, raising additional concerns about mercury,
arsenic and radioactive emissions.
Energy Consumption
Paper making is energy intensive, drawing larges amount of electricity from public utilities, or
forcing mills to build their own power plants. This is a signficant contributor to the air pollution
in our region, and to the hidden damages due to fuel extraction at the source (oil drilling, oil
spills, coal mining, pipelines, transmission lines, etc.)
Water Consumption
Paper-making is energy intensive, drawing a large amount of electricity from public utilities,
or forcing mills to build their own power plants. This is a significant contributor to the air
pollution in our region, and to the hidden damages due to fuel extraction at the source (oil
drilling, oil spills, coal mining, pipelines, transmission lines, etc.)
27 | P a g e
Socio-economic Status and Environmental Issues of Kaptai, Rangamati. By Abu Khairul Bashar
Solid Waste
Paper-making generally produces a large amount of solid waste. Unfortunately, landfilling
costs in northeast Wisconsin are relatively cheap (often less than $27 per ton), so the industry
has little incentive for making more efficient use of its materials. Because we have so many
paper recycling industries in our area, an even larger quantity of waste is generated. Paper
fibers can be recycled only a limited number of times before they become too short or weak to
make high quality paper. This means the broken, low-quality fibers are separated out to become
waste sludge.All the inks, dyes, coatings, pigments, staples and "stickies" (tape, plastic films,
etc.) are also washed off the recycled fibers to join the waste solids. The shiny finish on glossy
magazine-type paper is produced using a fine kaolin clay coating, which also becomes solid
waste during recycling.
Deforestation
Worldwide, enormous tracts of virgin forest are being felled for paper pulp production,
contributing to the world's tragic deforestation trends. Many Wisconsin mills import their pulp
and undoubtedly some of this pulp came from old-growth endangered forests. Citizen networks
have formed worldwide in an effort to save the last of these precious, irreplaceable places.
(Trees may be renewable, but ancient forest plant and animal communities are often not
renewable because of the complex ecological balance that was built over thousands, even
millions, of years in some of these forests.)
3.3.4 Scope of improving KPM'S Performance
Some suggestions are listed below for improving KPM'S Performance-
Look for new fibre source, new plantation area, new and unique fast growing pulp-
wood species, etc
Improvement of the share of recycle fibre in place of virgin fibre and RF handling
facilities, etc.
To keep intact the current improvement of the filler content with the addition of a
fraction of SBKP
Efficient
Operation of chemical recovery plant aiming at producing chemicals for kraft pulp.

3.4 Karnaphuli River Karnaphuli, the largest and most important river in Chittagong and the Chittagong Hill Tracts,
is a 667-metre (2,188 ft) wide river in the south-eastern part of Bangladesh. Originating from
the Lushai hills in Mizoram, India, it flows 270 kilometres (170 mi) southwest through
Chittagong Hill Tracts and Chittagong into the Bay of Bengal. The mouth of the river hosts
Chittagong's sea port, the main port of Bangladesh. Chittagong is situated on the banks of the
Karnaphuli River between the Chittagong Hill Tracts and the Bay of Bengal. The city is a
noteworthy seaside seaport city and monetary focus in southeastern Bangladesh. A water
treatment plant has been set up by Chittagong Port Authority to source water from the
Karnaphuli River for its uses. The plant will make the port self-reliant in its water needs.
3.5 Kaptai Dam
Kaptai dam is the one and only dam of Bangladesh that is used to generate hydro-electric
power. The only hydropower plant in the country is located at kaptai, about 50 km from the
port city of chittagong. This plant was constructed in 1962 as part of the 'Karnafuli
Multipurpose Project', and is one of the biggest water resources development project of
Bangladesh. The water storage capacity of the Kaptai dam is 11000 km2.
The earth-filled dam Kaptai is an earth-fill dam. It is 45.7m (36m MSL or mean sea level) high
and 670.6m long. The maximum width is 7.6m and width at the foot is 45.7m. The 16-gated
spillways, each 12.2m by 11.3m, can together pass a flow of 625,000 cusec. The average annual
flow in the reservoir is approximately 15,646 MCM. The flood absorption capacity is 8.25
million Ac-ft and the flooded area at 33m MSL is 777 sq km.
29 | P a g e
Socio-economic Status and Environmental Issues of Kaptai, Rangamati. By Abu Khairul Bashar
In 1962, the the dam, spillway, penstock and two units of powerhouses were built. Each of the
powerhouses was capable of generating 40MW of electricity. In November 1981 another
50MW generating unit was completed. In October 1988 the 4th and 5th generating units were
installed which raised the total generation capacity to 230MW. The total cost of Unit 1, Unit 2
and a part of Unit 3 was Rs. 503 million and the total cost of extension was Tk. 1,900 million.
The spillways was constructed on the left side of the main dam. The 16 gated (each 12.2 m X
11.3 m) spillway have discharge capacity of 625000 cusec. The construction of these system
(dam, spillways and others) required to excavate 113400 cubic m. The dead storage at 23.16m
above MSL is 1.18 million ac-ft. Flood storage capacity is 0.83 million ac-ft.

3.5.1 Issues of noncompliance in the past
The dam was constructed without any consultation with local indigenous comminutes. There
was no informed prior consent from the communities. The issues of resettlement of the
displaced were done in an abominable way. The Pakistan government and donor agency
USAID did not paid adequate attention to understand the culture and lifestyle of the indigenous
communities. The authority wrongly assumed that local indigenous communities were
“nomadic” hill people practicing jhum (slash and burn) cultivation and it was unnecessary to
design a permanent resettlement program for them. Though the indigenous people did move
from hill to hill but they had a long cycle of jhum cultivation. Before the submergence of the
area by the reservoir, the average cycle of jhum cultivation was 7-10 years, in some cases 10-
30 | P a g e
Socio-economic Status and Environmental Issues of Kaptai, Rangamati. By Abu Khairul Bashar
15 years. After the inundation of the river valleys, which took away 40% of the fertile land,
this cycle was shortened to 3-5 years as thousands of people, who used to grow rice, were
forced to take back jhum cultivation.
This lack of understanding of local indigenous culture contributed non-compensation. The dam
project did not have any adequate budgetary provision for resettlement. Initially, some
compensation was paid for the loss of land, trees and structures, most of which never reached
the people.
Figure-3.9: Kaptai Dam of Karnaphuli River
3.5.2 Biodiversity loss due to the Dam
The reservoir created by the dam has submerged a vast area of vegetation with rich biodiversity.
The reservoir has been home to a number marine species. Highlighted here will be one of them.
Locally know Shushuk, Platanista gangetica, or the dolphin is an endangered species
according to IUCN (IUCN, 1996). These dolphins have been reported from Kaptai reservoir
(Ahmed et al. 2001). In a recently conducted survey no dolphins were observed. This is a matter
of concern. The reservoir has been gathering silt. There has been no known study to assess the
loss of biodiversity and degradation of the reservoir.

3.6 Karnaphuli Hydro Power Station
Karnafuli Hydro Power Station the only hydropower plant in the country is located at kaptai,
about 50 km from the port city of chittagong. This plant was constructed in 1962 as part of the
'Karnafuli Multipurpose Project', and is one of the biggest water resources development project
of Bangladesh.
After being commissioned in 1962, the plant could feed the national grid with 80 MW of
electricity. In later years, the generation capacity was increased in two phases to a total of 230
MW. The plant not only plays an important role in meeting the power demand of the country
but is also vital as a flood management installation for the areas downstream.

Figure-3.10: Karnaphuli Hydro Power Station, Kaptai
3.6.1 Principle of Hydroelectric Power plant
In hydroelectric power plants the potential energy of water due to its high location is converted
into electrical energy. The total power generation capacity of the hydroelectric power plants
depends on the head of water and volume of water flowing towards the water turbine.
The water flowing in the river possesses two type of energy:
(1) The kinetic energy due to flow of water and
(2) Potential energy due to the height of water.
In hydroelectric power and potential energy of water is utilized to generate electricity.
Turbines: The next step is to convert this kinetic energy of water into mechanical energy. The water flows
from a height throw the penstocks which are the channeled vessels to the turbines which have
blades. The falling water has enough kinetic energy that when they strike hard with the blades
of the turbines, they start spinning which means that the kinetic energy is converted into
34 | P a g e
Socio-economic Status and Environmental Issues of Kaptai, Rangamati. By Abu Khairul Bashar
mechanical energy. The turbines resemble a lot with the windmills in which wind energy is
used instead of water. But the turbines use potential and mechanical energy of falling water to
convert into work.
Generators:
The shafts of the turbines convert the mechanical energy into electric energy. Basically, the
generators work on the principle of magnets which is that when you pass a magnet near a
conductor, electric current flows through it.
Rotor and stator: The rotor having field pole rotates on a specific speed. When it rotates it passes the field poles
across the stator to make sure that it has the same effect of electric field. The water should keep
on moving constantly to make sure that the amount of electricity produced is great. Static water
cannot generate electricity
Transmission lines: The electricity via power lines is transferred to substation which provides it to the consumers.
3.7 Socio-Economic Scenario or Status
Remoteness and poor communication in the part of the Hill Tracts has made it difficult to
integrate and mobilize the population as well as to provide basic services to the marginalized.
The illiteracy rate has been high due to low awareness of any benefits of education, long
distance of primary schools and language barriers. Poor health, malnutrition and inappropriate
hygiene were some of the prevailing phenomena among CHT population, and poverty has been
prevailing in the area. The status of the socio-economic indicators regarding, education, health
& nutrition and water & sanitation are described below in brief.
3.7.1 Education: Access and Utility
The literacy rate in the Hill districts is considered to be very low, compared to the average
national rate in Bangladesh. Previously, the enrolment rate of children in primary schools was
low, The dropout rate in primary schools was high, especially during the traditional Jhum
35 | P a g e

harvesting time, when many people shift to places away from their Paras/villages. But now
education is perceived as an essential element in the socialization and development process of
the CHTs region.

3.7.2 Health & Nutrition: Life is at risk
In the CHT, it is very difficult to the access to maternal health care services, lack of skilled
providers, and the low uptake of services, particularly by poor women are factors that
contribute to a relatively high rate of maternal deaths.In the Hill Districts approximately all
births take place at home, attended by family members or untrained traditional birth attendants.
trained and skilled health workers attend only about 4% of home deliveries. In cases of obstetric
complications transport to maternal wards is long and difficult.
Malnutrition rates for children aged 24-59 months are very high. Households have greater
difficulty in having micronutrient-rich foods compared to other parts of rural Bangladesh, and
small-scale localized famine like situations are reported each year, especially among poorer
ethnic groups living in the more remote areas. Preliminary findings of the World Food
Program’s Vulnerability Analysis Mapping (VAM) assessment in 2004 show that more than
50% of Unions (Local Administrative unit) have a high or very high level of food insecurity
36 | P a g e
Socio-economic Status and Environmental Issues of Kaptai, Rangamati. By Abu Khairul Bashar
compared to the rest of Bangladesh. Road networks and access to transport in CHT are
particularly difficult and contribute to household food insecurity.
Maternal and newborn health is linked with one another. A malnourished mother is at risk of
giving birth to a low weight baby. Low awareness among men women about nutrition,
requirements for iodine and Vitamin A and prevalence of infectious diseases, has contributed
to a high prevalence of infants born with low birth weight. Anemia has been a severe public
health problem among children and pregnant women. Malaria is the main cause of morbidity,
disability, and mortality in the CHT. The three districts have remote hilly and forested border
areas with intense perennial transmission of malaria. The people came here living from the
plain areas of the country are non-immuned and hence are more prone to malaria infection.

3.7.3 Water and Sanitation: An unmet problem
Low awareness of safe water and sanitation has also contributed to high rate of water-borne
infections. Before the ICDP intervention, the majority of people in CHT had low awareness
about safe water and sanitation. People collected their drinking water from unsafe sources such
as surface water and rivers that often were contaminated. Knowledge about water-borne
infections was scanty, and most of the villagers used hanging latrines or resorted to open
defecation, which in turn caused contamination of drinking water sources.From 2006 onwards
the situation had improved especially in Khagrachari and Rangamati district concerning
drinking water source and use of hygiene latrines. However the proportion still using hanging
latrines or open air defecation was reported to be relatively high in Bandarban (43%).

Sourch: MICS 2009 (BBS & UNICEF)
So, there was, and still is, a high demand for increased community awareness about early
childhood development and education, health and nutrition and about water and environmental
sanitation. The major threat to health is still malaria, as well as water-borne infectious diseases
like pneumonia and diarrhea. The awareness and use of safe water and sanitation has increased
but are still in many areas worrying low. The nutrition status of under-five children is estimated
to be below the national rural average. The total literacy rate is low, due to previous lack of
education facilities. Hence, there is still dearth of skilled health human resources and limited
health service facilities.
3.8 Kaptai Lake
Kaptai Lake, beautiful blue watery lake was made by man. Kaptai Lake is the largest man made
artificial freshwater body in Bangladesh.Its total surface area is about 68,800 hectar and
average water depth is about 9 meter and maximum depth of 32 meters.It is confined within
Rangamati district and embraces the upazilas of RangamatiSadar, Kaptai, Nannerchar,
Langudu, Baghaichari, Barkal, Jurachari and Belaichari. Since 1965 BFDC (Bangladesh
Fisheries Development Corporation) managed this lake for the fish production.

3.8.4 Biodiversity of Kaptai Lake at risk
Biodiversity of the Kaptai Lake has been severely affected due to climate change and lack of
proper preservation, which resulted in low fish production in the lake. The Kaptai Lake
comprises 68,800 hectare area. Different indigenous fish species along with aquatic animals
are gradually disappearing from the lake day by day. Moreover, the catch of carp variety fish
is reducing day by day due to destruction of its natural habitat, following adverse effect of
climate change. Researchers and scientists of fisheries sector have raised their concern over the
destruction of biodiversity of lake.
40 | P a g e
Socio-economic Status and Environmental Issues of Kaptai, Rangamati. By Abu Khairul Bashar
The Kaptai Lake is familiar as an abode of diversified local species of fish. In the initial stage
of commercial procurement, two species of shrimp, one species of dolphin and two species of
turtle along with around 78 species of fresh water fish were available in the lake. Out of those,
only 24 species of local fish are netted commercially now. In a latest joint research conducted
by Fisheries Research Centre and River Research Centre revealed that the change in
biodiversity created a negative impact on fish resources and aquatic animals of the Kaptai Lake.
Due to massive production of foreign species of fish like silver carp, tilapia, and bighead carp
the quantity. One of the main reasons behind reduction of local species is the shortage of food
for the species in the lake. In the meantime, local species named Sylon, Swarputi, Ghaora,
Bagha Air, Mohini, Bata and local Pangash have already abolished. Mohashole, Madhu Pabda,
Poa, Faishya, Tele Gulsha and Sada Ghonia are on the track of extinction. Day by day the
quantity of Rui, Katla, Bacha, Puti Pabda, Chitol are decreasing. On the other hand, the catches
of Taki, Puti, Bansh Pata, Bata, Koi, Magur, Bailya, Chela, and Champa are reducing at an
alarming rate.
M. A. Bashar, scientific officer of Rangamati District Fisheries Research Centre, told The Daily
Observer that joint and collaborative efforts are essential for the existence of fish species and
aquatic animals in the Kaptai Lake. Due to random use of current nets and massive catch of
fish fingerlings, the habitat of fish species in four main natural breeding places; Kachalong
channel, Maini Mukh channel, Barkol Channel, and Changi Channel, are becoming extinct.
Experts said in 1965-66, availability of Rui, Katal, Mrigel was 82 per cent of the total catch,
but now in 2014-2015, it has decreased to less than 5 per cent. On the other hand, availability
of small fish was 5 per cent in 1965-66 but now it is almost 90 per cent of the total fish catch.
According to a recent research, the production capacity of the Kaptai Lake is near about 15,000
metric tons.
Md. Saiful Islam, chief scientific officer of Rangamati District Fisheries Research Centre
informed that a special project has been initiated to revive national breeding places of carp fish.
It will increase the production of carp fish in near future, the officer expected.

3.9 Sheikh Rashel Aviary and Eco-Park
An eco- friendly park is established for facilitate tourism and recreation.“Sheikh Rashel Aviary
and Eco-Park, Rangunia” is situated at Nischintapur Mouza of Kodala beat of Rangunia Range
at Rangunia Up-Zilla in Chittagong district under the control of Chittagong South Forest
Division near to the hill tracts’ border within an area of 210.0 ha.It is 35.0 Km away from and
easternly to Chittagong city and nearer to the Chittagong-Kaptai Highway. The project is
nearby Chandraghona town and the renowned Karnafuly paper mill and Kaptai hydroelectricity
project. And also due to good communication system, a large number of tourists usually will
visit this place round the year. So, the project is already established an attractive eco-Park
within this forest area by established a required infrastructures and modern tourism facilities
(Ropeway-cable car, Artificial lake, Bird aviary, Deer park, Children park etc) for the nature
loving tourist from home & abroad.

Figure-3.13: Sheikh Rashel Aviary and Eco-Park
The projects objectives are in line with the national and sectoral objectives. Considering the
country’s objectives and sectoral targets, proposed actions focus on:
Establishment of plantations in the park area to enrich bird stock and variety of the
trees, herb and shrubs and
Establish and enrich facilities to attract tourists, recreation and nature lovers.
The area is characterized by natural hill forests, artificial plantations, hillocks, foot hills, tilas
and scattered baid (elevated) lands. Once this hilly area was very rich in natural and valuable
herbs, shrubs, trees, medicinal plants, birds and wild lives. Many of these species in course of
time have become rare/extinct due to high demographic pressure, land and environmental
degradations. As a result, some of the hills now are degraded. Some areas are now covered by
the old Teak plantations and the recent participatory SF plantations of exotic, indigenous and
native species e.g. akashmony, gamar and different long rotation species. Once upon a time the
area to habitat destruction and encroachment by man. A good numbers of birds are also found
there, which include doves, pigeons, magpie robin, red jungle fowl, wood peekers, owls, eagles,
vulture etc. Efforts are undertaken to protect and conserve the existing, rare and endangered
birds and to welcome the seasonal alien birds by establishing an aviary park as a shelter and
43 | P a g e

nursing place for those birds, the ever charming part of the nature’s beauty.Versatile plantations
are raised to create and develop sources of foods and proper for birds (e.g existing, rare and
endangered birds) in the available vacant area and during the second rotation of the existing
participatory Social forestry plantation. Birds enclosures and other aviary facilities are already
established while a sound habitat will exist for birds.

Socio-economic Status and Environmental Issues of Kaptai, Rangamati. By Abu Khairul Bashar
4.1 Conclusion
Kaptai dam is an earth-fill embankment dam. This embankment dam means that is made of
compacted earth and rely on their weight to hold back the force of water. Here it does not mean
that it is used to manage or prevent water flow into specific land region. Prime objective of
Kaptai Lake is Hydroelectric power generation.For this Kaptai Dam was constructed
in1961.There are five units exist in the Karnaphuly Hydroelectric Project for power
generation.At present three units are under repaired.Generally 45 to 50 megawatt power
generated from each unit.So power generation capacity is aound 230 megawatt.
Karnafuli Hydro Power Station the only hydropower plant in the country is located at kaptai,
about 50 km from the port city of chittagong. This plant was constructed in 1962 as part of the
'Karnafuli Multipurpose Project', and is one of the biggest water resources development project
of Bangladesh. After Bangladeshi independence from Pakistan in 1971, indigenous leaders’
appeals to the new government for autonomy and constitutional recognition were rejected.
Subsequent governments opted for a military escalation of the area that triggered a protracted
armed conflict. The government resettled more than 400,000 landless Bengalis into the region
to outnumber the indigenous population and overwhelm the resistance. This changed the
demographics completely. In a series of massacres and other human rights violations thousands
of indigenous people were killed and women raped and vast lands were grabbed by settlers and
vested interests. Hanging Bridge is 335 feet long bridge across a portion of the Kaptai lake is
an icon of Rangamati. Actually Rangamati is famous for this bridge.It's really a very beautiful
bridge. Every year thousands of people come here to visit this bridge and lake. “Sheikh Rashel
Aviary and Eco-Park, Rangunia” is situated at Nischintapur Mouza of Kodala beat of Rangunia
Range at Rangunia Up-Zilla in Chittagong district under the control of Chittagong South Forest
Division near to the hill tracts’ border within an area of 210.0 ha.
