“I have given you all kind of resources ,you have to utilize them in a proper way for your better life.’’ ….In the holy Quran, the Almighty indicates about the

natural resources.

INTRODUCTION

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

aim

SCOPEFor better assimilation and understanding the topic can be discussed under following heading.

a. Land resources and natural region of Bangladesh

b. Mineral resourcesc. Water resources: Rivers and lakesd. 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.

Definition

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.

CLASSIFICATION

abundance

Exhaustible

Renewable

Non renewable

inexhaustible

ex:air,sand

According to Distribution

Wildlife resources

Geological resources (valleys, minerals, precious metals etc)

Crop resources (agricultural)

Atmospheric resources (rainfall, sunlight, temperature etc

Human resources (the population at large)

Microbial resources (organisms that aren't visible to the naked eye)

Animal resources

Hydro geological resources (water bodies of all kinds)

Aquatic / Marine resources

Forest resources (pertaining to plant and tree life)

NATURAL RESOURCES

RENEWABLE RESOURCE

• 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)

NON-RENEWABLE

• 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 resources”.• 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 RESOURCE

• COAL • Rocks • Petroleum and Natural Gas• OIL • NATURAL GAS • OIL SHALE AND TAR SANDS • NUCLEAR POWER• Ores

USES OF NATURAL RESOURCES

Natural Resources Uses

Air (Wind) 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.

Soil

Used as the primary nutrient source for plants. It is the habitat of many organisms.

Solar Light

Provide light, energy and help to plants for making their foods.

Wood / Tree

Used as construction material. Used to make utensils, furniture and sporting equipments.

Water 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

WATER

• 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 Bangladesh. 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.

MINERAL RESOURCES

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 eastern parts; Pleistocene residuum (8%) in the north western, mid northern

& eastern parts; Holocene deposits (80%) consisting of unconsolidated SAND, SILT and CL AY

MINERAL RESOURCES

• 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.

MINERAL RESOURCES

Use of natural gas Meet 70% of the total demand of fuelTotal gas block 23 numbers including block 9Stock of natural gas 28.4 trillion cubic feetPrimarily recoverable natural gas stock

• 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

Coal

NATURAL GASIt 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

powering vehicles • Natural gas is a mixture of gases

methane ethane propane butane.

Bay of Bengal is an important resource of Bangladesh. Chittagong Port is one of the biggest seaports of the world.

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.

SUNDERBAN

SUNDERBAN

• 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

Sunderbans, • Prawns and lobsters arc available in plenty for local

consumption and export.

RECOMMENDATION

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 natural resources.

CONCLUSION

DO we know actually what we have?
