What is Natural Resource?

Resources or natural resources are any form of matter or energy obtained from the physical environment that meet human needs.

This definition of natural resources is not as simple as it appears. Most resources are created by human ingenuity. Oil was once a useless fluid until humans learned how to locate it, extract it from the ground, and separate it by distillation into various components such as gasoline, home heating oil, and road tar.

NATURAL RESOURCES

Classification of Natural Resources

Classification of Natural ResourcesRENEWABLE AND NON RENEWABLE RESOURCES

Renewable resources are generally living resources (fish, and forests, for example), which can restock (renew) themselves if they are not overharvested.

Non-renewable resources is a natural resource that cannot be re-made or re-grown. Often fossil fuels, such as coal, petroleum and natural gas are considered non-renewable resources.

Classification of Natural ResourcesACTUAL VS. POTENTIAL RESOURCES

On the basis of their stages of developments, resources can be classified into both Actual and Potential resources: The resources held actually in stock are called Actual

resources. Even the actual source of resources may not be possible to be

used to their full. The portion that can be used profitably with the help of

available technology is termed as Potential resourcs. The size and quantity of a potential resource may change with

changes in technology and time.

ACTUAL

CLASSIFICATION OF THE RESOURCES

POTENTIAL

*Mineral deposits* Soil* Timber* Protected natural territories * Suitable microclimate for living and recreation

* Wave energy * Earthquake energy * Iceberg freshwater

Classification of Natural ResourcesBIOTIC VS. ABIOTIC NATURAL RESOURCES

Based on origin or source- Biotic resources are derived from animals and plants

(living world). Abiotic resouces are derived from the non-living world

e.g. land, water, and air. Mineral and power resources can also be abiotic resources

some are derived from nature.

Classification of Natural ResourcesUBIQUITOUS VS. LOCALIZED NATURAL RESOURCES

Based on Distribution-Ubiquitous Resources are found everywhere (e.g., air, light, water). Localized Resources are found only in certain parts of the world (e.g., copper and iron ore, geothermal power).

Ubiquitous Resources Localized Resources

Natural Resources and Nations Status A nation's natural resources often

determine its wealth and status in the world economic system, by determining its political influence.

Developed nations are those which are less dependent on natural resources for wealth, due to their greater reliance on infrastructural capital.

For example, the United States used coal as an export in the early 1900s, and also as a main resource fuel in key industries for production. Eventually, as transportation costs went down with time, minerals used as resources became commodities and were traded at world prices.

World Reserve & Consumption of Natural Resources(NR)

Use of Natural Resources (Ethical)

As the provision of natural resources decreases, prices go up, unemployment climbs, and it is the availability of natural resources that largely dictates the migration of population, formation of new settlements and the abandonment of inhabited places in the world.

Historically, the world society has responded to a decrease in the availability of resources with a price rise or replacement of one resource with another.

For example, in Great Britain, around 1800, in response to total deforestation people started using coal instead of firewood, while a century later oil became the main energy resource, cheap and widely available.

The availability of all the Earth’s resources is limited in a way, either due to insufficient reserves, complicated extraction or transportation, inadequate technology of extraction and processing.

Thus, a moment comes when the demand for certain resources exceeds that of their extraction.

Society responds to this by a attempts to develop the research and extraction of mineral deposits and to improve extraction technologies.

It stipulates that, with a fixed resource, a unit of another resource(-s) will yield a progressive decline in productivity when a certain output level is exceeded.

Natural Resources

Common 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 Resources 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 Bills, 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.

#Most of Bangladesh lies within the broad delta formed by the Ganges and Brahmaputra 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.

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# 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.
