Bangladesh is the most blessing child of nature and the
country is embellished with plenty of resources. It’s a
land of enormous beauty, hundreds of serpentine
rivers, crystal clear water lakes surrounded by
evergreen hills. We have luxuriant tropical rain forests,
beautiful cascades of green tea gardens and world’s
largest mangrove forest preserved as world heritage.
To inspire people with new hope by informing
them about the resources what we have
For better assimilation and understanding the topic
can be discussed under following heading.
a. Land resources and natural region of Bangladesh
b. Mineral resources
c. Water resources: Rivers and lakes
d. Bay of Bengal
e. Plant and Animal life: Flora and Fauna
• Any material which is part of earth and satisfies human
need and adds value is called as resource. Example: rocks,
minerals, soil, rivers, plants & animal.
Materials occurring in the environment thus are nothing more than
‘neutral matter’ until people recognize their presence, attach great
importance to them, and develop means to capitalize on them.
Then the natural materials fulfill a function.
Resources are commonly classified with respect to their
exhaustibility. The differentiation between exhaustible
and inexhaustible resources only focuses on their
quantitative availability and not on their potential for
natural growth and recycling.
According to Distribution
National: minerals, lands
Multinational: rivers, lakes
International, air, solar
Forest resources (pertaining to plant and tree life)
Aquatic / Marine resources
Hydro geological resources (water bodies of all kinds)
Microbial resources (organisms that aren't visible to the naked eye)
Human resources (the population at large)
Atmospheric resources (rainfall, sunlight, temperature etc
Crop resources (agricultural)
Geological resources (valleys, minerals, precious metals etc)
• Are resources that have a continuing process of renewal
and supply in nature.
• Commonly named “flow resources”.
Example: Solar energy crops (food and fiber, water, soil,
air, wind, biomass, organic matter)
• The resources whose physical quantity does not increase
significantly with time
• The rate of renewal is so slow as to be negligible
• The non-renewable resources are often defined as “stock
• Most developed nations are dependent on non-renewable energy
sources such as fossil fuels (coal and oil) and nuclear power.
• Industrialized societies depend on non-renewable energy sources.
EXAMPLE OF NON-RENEWABLE
• Petroleum and Natural Gas
• NATURAL GAS
• OIL SHALE AND TAR SANDS
• NUCLEAR POWER
USES OF NATURAL RESOURCES
Required for all living things for breathing, Use to produce wind energy.
Animals / Plants
Provide food, cloth, shelter, medicine. Animal dung can be used as fuel/fertilizer.
Used as the primary nutrient source for plants. It is the habitat of many organisms.
Provide light, energy and help to plants for making their foods.
Wood / Tree
Used as construction material. Used to make utensils, furniture and sporting
Used in household, agriculture and transportation.
NATURAL RESOURCE IN BANGLADESH
• Natural resources are most important for a country. There are many states
which are straightly depends on natural resources. Bangladesh is a
developing country and area is small. We have also some natural
resources some are renewable and some are non renewable.
The natural resources of Bangladesh are mainly Energy, Water, Fish, Forest
etc. and Non-renewable Natural Resources are Gas & Oil, Coal, Rock, Sand
• It is the renewable natural resources of Bangladesh.
• There area total of 230 rivers in Bangladesh.
throughout the country there are
bils, haors and lakes that meet
the need of drinking, bathing and irrigating water.
• Two main rivers of the country are the Brahmaputra and the
Gangas account for more than 80% of stream flows.
LAND RESOURCES & NATURAL REGION OF BANGLADESH
Most of Bangladesh lies within the broad delta formed by the
Ganges and Bramaputra rivers.
It has 59% of agricultural land, which is the biggest asset of
According to BBS 2009 total food crop demand is 22.55 million
metric ton and total food crops production is 25.097 million
metric ton with a surplus of 2.547 million metric ton.
Besides, 62 % of the total manpower is engaged in agriculture.
Geologically Bangladesh occupies a larger part of the BENGAL BASIN
and the country is covered by Tertiary folded
sedimentary rocks (12%) in the north, north eastern and
Pleistocene residuum (8%) in the north western, mid northern &
Holocene deposits (80%) consisting of unconsolidated SAND, SILT
and CL AY
• Bangladesh is receiving substantial international
interest since it is told that it might have huge
gas and oil deposits. This is an fact a prime
location for hydrocarbon resource.

• Barapakuria Coal Mine project has been started in 1994.
It has a proven reserve of 303 million metric tons. This
coal can be used for power generation in this country in
future. The Madhyapara Hard Rock project is expected
to produce 1.65 million tons of hard rock which can be
exported to different parts of the world.
• Fossil fuel that forms when wetland plants die,
become buried, and undergo physical and
chemical changes over millions of years
• Starts out as peat~50% carbon
• Over time peat becomes lignite ~ 70 % carbon
• Lignite becomes bituminous coal (soft coal)
~ 85 % carbon
• Bituminous coal becomes anthracite
(hard coal) > 90% carbon…
burns very cleanly
It is cleanest burning fossil fuel
• Propane and butane are removed from the natural gas and
made into liquefied petroleum gas (LPG)
• Natural gas is highly flammable and is odorless
• Natural gas is used primarily for heating, cooking, and
• Natural gas is a mixture of gases
methane ethane propane butane.
BAY OF BENGAL
Cox's Bazar is the longest beach of the world having a length of 155 km.
Shrimp industry is based on this Bay of Bengal and the country is earning a
huge amount of foreign currency.
• 525- recorded species of birds, 350 arc resident.
• Of the 200 species of mammals,
• the pride of place goes to the Royal Bengal Tiger of the
• Prawns and lobsters arc available in plenty for local
consumption and export.
Pollution of Resources like rivers, lakes, Bay of Bengal has become a
threat and necessary actions should be taken for the sustainability
of these resources.
Resources like rivers, forests should be protected and necessary
steps should be taken to avoid illegal encroachment.
Judicial decisions should be applied to make the best use of our
mineral resources like Gas, oil and coal.
Modern technology should be applied for optimum use of our
DO we know actually what we have?
