Takeaways

  • 🏫 Resources are essential for satisfying our needs, including learning resources like schools, teachers, and technology.
  • 🌿 Resources are classified based on origin (biotic or abiotic), exhaustibility (renewable or non-renewable), ownership (individual, community, national, international), and development status (developed, potential, stock, reserves).
  • 🌱 Biotic resources come from living things, while abiotic resources come from non-living things like minerals and metals.
  • πŸ”‹ Renewable resources can be regenerated, like solar and wind energy, while non-renewable resources, like fossil fuels and minerals, cannot be reproduced once used.
  • 🌍 Resources can be owned by individuals, communities, countries, or be international, like Antarctica and certain ocean areas.
  • πŸ”§ Developed resources are fully utilized, while potential resources are known but not yet fully exploited. Stock resources cannot be used due to lack of technology, and reserves are resources set aside for future use.
  • 🌳 Sustainable development involves using resources wisely to ensure availability for future generations, preventing rapid depletion, economic inequality, and environmental issues.

  • 🌾 Soil, a crucial renewable resource, varies across India and includes types like alluvial, black, red and yellow, laterite, arid, and forest soil, each with specific characteristics and uses.

Q & A

  • What are resources, and what criteria make them useful for satisfying our needs?

    -Resources are things available in our environment that can be used to satisfy our needs, provided they are technically feasible, financially viable, and culturally acceptable.

  • How can resources be classified based on their origin?

    -Resources can be classified as biotic, which come from living things like forests, animals, and humans, and abiotic, which come from nonliving things like rocks, minerals, and metals.

  • What is the difference between renewable and non-renewable resources?

    -Renewable resources, like solar and wind energy, can be regenerated once used, whereas non-renewable resources, like fossil fuels and minerals, cannot be reproduced once used and are lost forever.

  • How are resources classified based on ownership?

    -Resources can be individual (owned by a person), community-owned (open to all community members), national (within a country's political boundaries), and international (found in areas not owned by any particular nation).

  • What are developed resources, and how do they differ from potential resources?

    -Developed resources are those where minerals have already been discovered and production is ongoing, whereas potential resources are known to exist but are not yet being fully utilized.

  • What is the difference between stock and reserves in resource terminology?

    -Stock refers to resources that cannot be used due to the unavailability of suitable technology, while reserves are resources not being utilized to their full capacity but can be used in the future.

  • What is sustainable development, and why is it important?

    -Sustainable development is the wise use of resources without damaging the environment to ensure enough resources for future generations. It is important to prevent rapid resource depletion, economic divide, and environmental problems.

  • What was the significance of the Earth Summit in Rio de Janeiro in 1992?

    -The Earth Summit in Rio de Janeiro in 1992 gathered leaders from over 100 countries to address environmental protection and sustainable development, resulting in the Declaration on global climatic change and biological diversity, global forest principles, and Agenda 21 for sustainable development.

  • Why is resource planning important for economic growth?

    -Resource planning is important because the mere presence of resources is not enough for development. It involves identifying, surveying, mapping resources, evolving technology, skilled personnel, and institutions, and ensuring equitable distribution for sustained economic development.

  • How does land degradation occur, and what steps can be taken for land conservation?

    -Land degradation occurs due to natural agents like wind and water erosion and human activities like deforestation, overgrazing, mining, and improper irrigation. Steps for land conservation include afforestation, controlled grazing, stabilizing sand dunes, proper disposal of industrial effluents, and monitoring soil conditions.

unavailability of suitable technology

play05:15

for example hydrogen is present in the

play05:19

atmosphere as well as in water fusing

play05:23

two hydrogen atoms can create

play05:26

inexhaustible and clean energy

play05:29

but no suitable technology exists to

play05:33

achieve this in a practical way

play05:36

hence we can refer to hydrogen as stock

play05:47

you

play05:49

on the other hand reserves are a

play05:53

resource which is not being utilized to

play05:57

its full capacity but it can be used at

play06:01

any time in the future

play06:03

for example ethanol

play06:06

ethanol is an alcohol extracted from

play06:10

sugarcane and can be used as an

play06:12

alternative motor fuel

play06:15

resources that can be used today but are

play06:19

preserved to meet future requirements

play06:22

are called reserves

play06:30

let's quickly look at the classification

play06:33

of resources based on their origin

play06:35

exhaust ability ownership and status of

play06:40

development consider an example but all

play06:43

local people have equal access to forest

play06:46

resources

play06:49

they use the resources wisely without

play06:52

damaging the environment and make sure

play06:55

that their future generations also have

play06:58

enough resources available to them

play07:01

this is called sustainable development

play07:07

what will happen if individuals start

play07:10

using resources indiscriminately to make

play07:13

a quick profit

play07:17

this would lead to a rapid depletion of

play07:20

resources

play07:23

this would also create an economic

play07:24

divide in the society as some persons we

play07:29

get richer than the others

play07:33

this would also lead to environmental

play07:36

problems like pollution and land

play07:39

degradation and contribute to ecological

play07:43

problems like global warming

play07:48

and ozone layer depletion

play07:51

the growing worldwide concern for

play07:54

sustainable development resulted in the

play07:56

first Earth Summit in Rio de Janeiro in

play08:00

Brazil in June 1992

play08:06

at Rio de Janeiro leaders from over

play08:09

hundred countries gathered to address

and sustainable socio-economic

play08:17

development

play08:20

leaders signed the Declaration on global

play08:23

climatic change and biological diversity

play08:26

and approved the global forest

play08:29

principles

play08:32

a trio the leaders also adopted agenda

play08:35

21 which is a declaration to achieve

play08:39

global sustainable development in the

play08:41

21st century

play08:45

agenda21 aims to prevent environmental

play08:48

damage and fight poverty and diseases

play08:51

through global cooperation

play08:55

it also aims to encourage local

play08:58

governments to form their own agenda 21

play09:01

based on local issues

play09:07

observe the items in this table

play09:10

can you imagine where the resources

play09:13

needed to arrange this simple breakfast

play09:15

came from

play09:18

the wheat used to make the flour for the

play09:20

bread might have come from Punjab or

play09:23

Madhya Pradesh

play09:26

the bread itself might have been baked

play09:28

in a factory in your city

play09:31

the butter and the milk used to make it

play09:34

might have come from a city in Gujarat

play09:38

the delicious jam and the fruits used to

play09:41

prepare it might have come from an

play09:43

orchard in Himachal Pradesh

play09:46

the tea might have come from Assam West

play09:50

Bengal Kerala Tamil Nadu

play09:55

even the steel used to make your plate

play09:58

might have come from the iron ore mined

play10:00

in Jharkhand or chattisgarh

play10:05

the resources in our country are not

play10:08

distributed uniformly across all its

play10:10

regions

play10:12

for example some states and India are

play10:15

rich in food grains while others are

play10:18

rich in minerals

play10:21

the mere presence of resources is not

play10:24

enough for the development of the region

play10:27

in India Mata Pradesh is rich in

play10:30

minerals but lacks communication and

play10:34

transport facilities

play10:37

so what else do you think is required

play10:40

for economic growth

play10:42

besides the availability of resources

play10:47

this is where resource planning comes in

play10:51

it involves the identification and

play10:54

inventory of resources

play10:58

planning with the appropriate technology

play11:01

skilled Human Resources setting up of

play11:05

suitable institutions for the

play11:08

implementation of resource development

play11:09

plans and equitable distribution of

play11:13

available resources for sustained

play11:16

economic development

play11:19

matching these with national development

play11:22

plans

play11:26

India started with its resource planning

play11:29

efforts with the first five-year plan

play11:32

launched after independence

play11:35

what are the different activities

play11:37

involved in resource planning in India

play11:41

resource planning involves identifying

play11:44

and estimating the resources available

play11:46

by surveying and mapping

play11:50

resource planning involves evolving

play11:53

technology skilled personnel and

play11:57

institutions to implement resource

play12:00

development plans

play12:02

the sauce planning also involves

play12:05

continuously monitoring and guiding

play12:08

resource development plans to match the

play12:11

overall national development goals

play12:15

the availability of resources is limited

play12:19

irresponsible and overuse of resources

play12:23

can lead to several social economic and

play12:28

environmental problems

play12:31

this is the reason why we must plan for

play12:34

the future and start conserving our

play12:37

resources at own levels

play12:41

whether it is water or oil a drop saved

play12:44

today is a job available for tomorrow

play12:48

India is the seventh largest country in

play12:51

the world with the geographical area of

play12:53

about three point two eight million

play12:56

square kilometers this land is a

play12:58

valuable resource that supports our

play13:01

population

play13:03

buildings

play13:06

farmlands

play13:09

and forests

play13:11

and also provides us with rich mineral

play13:18

and soiled resources

play13:27

India has widely different geographical

play13:30

features

play13:32

from lofty mountains in the not

play13:35

to vast plains and plateaus in the

play13:38

central region

play13:41

from deserts in the West to dense

play13:44

forests in the east

play13:47

and islands in the south

play13:50

besides a long coastline

play13:56

the mountains allow perineal flow of

play13:59

rivers like the Ganges

play14:02

the Brahmaputra

be enhanced tourism and ecological

play14:11

prospects to

play14:16

a plateau is an elevated comparatively

play14:21

level expanse of land

play14:24

plateaus are rich reserves of minerals

play14:28

fossil fuels and forests

play14:35

land in India can be divided into three

play14:38

main relief features

play14:41

around 30% of our land is occupied by

play14:44

mountains

play14:47

43% of it is plane

play14:51

and 27% is in the form of Plateau

play15:00

depending on their use our land

play15:03

resources can be classified as forests

play15:07

net zone area or total area under

play15:10

cultivation fallow lands other

play15:15

uncultivated land and land not available

play15:18

for cultivation

play15:21

Salo land can be further divided into

play15:24

current fallow

play15:26

which is land not cultivated for one or

play15:29

less than one year

play15:32

and other than current fellow

play15:35

which is land that has remained

play15:37

uncultivated for one to five years

play15:41

uncultivated land other than fallow land

play15:44

is divided into permanent pastures land

play15:48

under miscellaneous tree crops and land

play15:51

left uncultivated for more than five

play15:54

years

play15:56

this other than current fallow land is

play15:59

either of poor quality or cost too high

play16:03

to cultivate

play16:05

hence sometimes it is cultivated once in

play16:10

two or three years

play16:13

land not available for cultivation is

play16:15

either barren wasteland

play16:20

like the salty plains of the run of cut

play16:29

all land used for non agricultural

play16:32

purposes like building houses

play16:40

play16:45

and factories

play16:51

your two pie charts that show the

play16:54

land-use pattern in India in 1962 61 and

play16:59

2008 to 2009

play17:02

let us compare the data and see how the

play17:05

land-use pattern has changed from 1960

play17:08

to 2009 in India

play17:14

observe but there is no major change in

play17:17

the Nets own area during the period

play17:22

note that the area under forests

play17:24

increased marginally from 1960 to 2009

play17:29

but it is still way below the required

play17:32

33% as planned in the national forest

play17:35

policy formulated in 1952

play17:46

you

play17:49

permanent pastures and grazing grounds

play17:52

decreased during the period

play17:55

this is not a good sign for thousands of

play17:57

people engaged in cattle drink

play18:02

the percentage of barren wasteland

play18:03

decreased by almost half during the

play18:07

given period

play18:09

however this reclaimed land is used

play18:13

mainly for non agricultural purposes

play18:18

current fallow and other than current

play18:21

fallow land also increased during this

play18:24

period

play18:26

however

play18:28

if these lands are included in the Nets

play18:30

own area since these lands are

play18:34

cultivated once or twice in two or three

play18:36

years

play18:38

the percentage of Nets own area goes up

play18:41

to 54%

play18:46

continues and indiscriminate use of land

play18:49

resources without taking appropriate

play18:51

measures results in conversion of

play18:54

cultivable land into barren wasteland

play18:57

and exploitation of our land resources

play19:04

this is called land degradation

play19:11

we have about 130 million hectares of

play19:15

degraded land in India

play19:19

to give you a sense of the size it is

play19:22

roughly equal to one third of the total

play19:24

area of our country

play19:28

out of this 56 percent is water eroded

play19:32

area 10% is wind eroded

play19:38

28% is forest degraded area and 6% has

play19:44

saline and alkaline deposits

play19:54

natural agents like wind and water

play19:58

constantly keep eroding and degrading

play20:01

land

play20:03

however human activity has contributed

play20:07

to and increased the pace of this

play20:10

natural land degradation

play20:18

here are the main factors contributing

play20:21

to land degradation in India

play20:25

deforestation removes the green cover

play20:27

required to protect land from soil

play20:30

erosion by wind and water

play20:34

and thus contributes to land degradation

play20:42

in some parts of India over grazing by

play20:46

cattle has converted permanent pastures

play20:49

into barren land leading to land

play20:53

degradation

play20:55

examples are the states of Maharashtra

play20:59

mati Pradesh Gujarat

play21:03

and Rajasthan

play21:11

indiscriminate deforestation and

play21:14

excavation done as part of mining

play21:17

activity and quarrying also causes land

play21:20

degradation

play21:23

jerk and shut this girl

play21:27

Arisa

play21:29

and Madhya Pradesh have suffered

play21:31

deforestation due to mining

play21:41

you

play21:44

over irrigation of cultivated land in

play21:47

some parts of India leads to water

play21:49

logging

play21:51

this increases the saline and alkaline

play21:55

levels in the soil leading to land

play21:58

degradation

play22:01

you find this in Punjab Haryana and

play22:05

western Uttar Pradesh

play22:09

disposal of solid and liquid waste by

play22:12

industries on surrounding land or water

play22:15

bodies has also become a major cause of

play22:19

land degradation and water pollution

play22:23

Industrial activities like grinding of

play22:26

limestone calcite

play22:29

and soapstone

play22:32

which release dust

play22:34

retards water infiltration into the soil

play22:44

this brings us to the question

play22:47

what steps can be taken to control the

play22:50

problem of land degradation

play22:53

the solution lies in taking steps for

play22:56

land conservation

play22:59

some steps for land conservation are a

play23:02

forestation

play23:04

controlled grazing and mining activity

play23:09

stabilization of sand dunes by growing

play23:12

Tonie bushes proper disposal of

play23:15

industrial effluents after treatment and

play23:18

continuous monitoring of soil conditions

play23:21

soil is formed over millions of years by

play23:26

weathering of rocks and minerals and

play23:28

also by natural agents like variation in

play23:33

temperature climate

play23:36

wind leashes and running water

play23:42

the important factors that influence

play23:45

Sony formation are relief parent rock

play23:51

vegetation and other life-forms and most

play23:55

important of all time

play23:59

chemical and organic changes also take

play24:02

place in the soil

play24:04

SOI is a natural abiotic renewable

play24:09

resource

play24:12

it contains inorganic and organic matter

play24:15

such as humors

play24:23

soil is an essential resource

play24:27

a majority of plant and animal life on

play24:29

the earth

play24:32

the layer of soy may be a few

play24:35

centimeters to several meters thick in

play24:38

different regions

play24:41

usually when we see soil we refer to the

play24:45

thin layer of the topsoil or the fine

play24:48

upper layer of soil in a region

play24:56

based on their physical and chemical

play24:58

properties

play25:01

texture and color

play25:06

soit's in india can be classified as

play25:09

alluvial

play25:11

black site

play25:13

red and yellow soil

play25:16

letter right

play25:18

edit

play25:20

and forest soil

play25:23

let us learn more about each of these

play25:26

types of soils

play25:28

the northern plains of India a meet of

play25:31

fertile alluvial soils which extend to

play25:35

Gujarat and Rajasthan through a narrow

play25:38

corridor formed by the Indus the Ganga

play25:42

and the Primeau Putra river systems

play25:47

alluvial soils are also found in the

play25:50

eastern coastal plains

play25:52

and Delta's of the godavari the Mahanadi

play25:57

the krishna and the cavity

play26:04

alluvial soil is a mixture of sand

play26:08

silt

play26:11

and Klee

play26:13

the new alluvial soils called cutter

play26:17

found in the Gangetic Plains had small

play26:21

particles and a fine texture

play26:26

the old alluvial soils called Bunga

play26:29

found near the river valleys are coarser

play26:32

and contain more pieces of rocks called

play26:35

conker

play26:39

in other words cupboard is more fertile

play26:42

than the Bunga

play26:50

the fertile alluvial soils are rich in

play26:53

potassium

play26:55

phosphoric acid and lime

play27:00

and an ideal for growing sugar cane

play27:04

wait

play27:06

vice

play27:09

pulses

play27:12

and cereal crops

play27:15

due to the richness of soil the regions

play27:19

of alluvial soils are densely populated

play27:22

and the level of cultivation is high

play27:29

black soy also called Recor is found in

play27:34

the Deccan Plateau spread over

play27:37

Maharashtra

play27:40

Saurashtra

play27:43

Marva

play27:45

mata Pradesh

play27:48

and chappies get

play27:51

black soil is formed by the climatic

play27:54

conditions and weathering of volcanic

play27:57

rocks found in this region

play28:03

SOI is rich in calcium carbonate

play28:09

magnesium

play28:12

and lime

play28:15

it also has good water retention

play28:17

properties due to the fine clay

play28:19

particles

play28:22

however it is poor in phosphorus which

play28:26

is a very important nutrient in soil

play28:30

this type of soy has to be immediately

play28:33

tilled after the first shot of monsoon

play28:37

to prevent it from getting sticky

play28:41

it is ideally suited for the cultivation

play28:44

of cotton and is also called black

play28:48

cotton soil

play28:55

you

play28:57

Vette and yellow soils are found in

play29:01

southern and eastern parts of Deccan

play29:03

Plateau

play29:04

southern genetic claims along the

play29:08

western cards and some parts of Orissa

play29:11

and Chiapas go

play29:15

the red color is due to the presence of

play29:18

mine in the rocks from which the soil

play29:20

was formed

play29:22

and appears yellow when wet

play29:26

the high iron content makes this type of

play29:29

soil good for cultivating various types

play29:32

of drams

play29:34

groundnuts

play29:36

and Casta seeds

play29:39

you

play29:44

you

play29:46

laterite soils are found in kerala

play29:50

good Nautica

play29:53

Multi pradesh

play29:55

Tamilnadu

play29:58

and parts of Orissa and Assam

play30:02

all these areas experience high

play30:05

temperature and heavy rainfall

play30:09

the soil develops by leaching due to

play30:13

heavy rains

play30:16

laterite soy is low in organic

play30:18

components

play30:20

can be meat cultivable with the use of

play30:23

adequate fertilizers and menus

play30:28

it is good for cultivation of tea

play30:32

coffee

play30:34

and cashew nuts

play30:41

you

play30:45

Everitt means dry true to its name arid

play30:50

soil is found in western Rajasthan

play30:55

and parts of Kutch region in Gujarat

play30:59

that received very little rainfall

play31:02

it is reddish-brown in color and has a

play31:05

sandy texture

play31:08

due to high temperatures and dry climate

play31:11

arid soy is low in moisture and organic

play31:16

content and has high salt content

play31:22

the salt content is so high that common

play31:26

salt is obtained by mere evaporation of

play31:29

the water

play31:33

forest soils are found in the

play31:36

mountainous regions of the Himalayas

play31:40

from Kashmir

play31:43

to Arunachal Pradesh

play31:47

most of these regions experience a cool

play31:50

climate with abundant rain and snowfall

play31:57

the texture of forest soils varies from

play32:00

coarse-grained on mountain slopes to

play32:03

lomi in river valleys

play32:06

for the soy in snow-covered areas is

play32:10

often acidic with low humors content

play32:16

however wheat

play32:20

rice

play32:24

sugar cane

play32:27

and always seats

play32:31

a cultivated in forest soils of many

play32:35

parts in Jammu and Kashmir

play32:39

and Arunachal Pradesh

play32:43

SOI is an essential natural resource

play32:45

that supports a majority of plant and

play32:48

animal life on the earth

play32:51

it is a renewable resource

play32:55

however it takes hundreds and thousands

play32:57

of years for a thin layer of soy to form

play33:03

without vegetation cover the soil that

play33:06

takes hundreds of years to form can be

play33:08

washed away in a few hours of heavy rain

play33:12

the loss of soil cover due to natural

play33:14

agents like wind and running water is

play33:18

called soy erosion

play33:27

some human activities have increased the

play33:30

rate of soil erosion by natural agents

play33:33

like wind and running water

play33:37

what human activities do you think are

play33:39

responsible for soil erosion

play33:43

the roots of plants and trees keep the

play33:46

soil moist and hold the soil particles

play33:49

together

play33:56

humans destroy vegetation cover by

play33:59

deforestation overgrazing construction

play34:03

and mining activities

play34:07

without vegetation cover soil becomes

play34:11

dry and loose and gets easily eroded

play34:22

defective farming methods like plowing

play34:25

up and down the slope increase the speed

play34:28

of water flowing down the slope

play34:31

this increases the rate of soil erosion

play34:40

running water cards deep channels

play34:43

through clay soils

play34:46

this is called gully erosion which

play34:50

converts the land into bad land making

play34:52

it unsuitable for cultivation

play34:56

such lands also called ravines are

play35:00

prominent in the tumble basin

play35:09

when flowing water washes away the

play35:11

entire sheet of topsoil in a region it

play35:13

is called sheet erosion

play35:22

winter erosion occurs generally in areas

play35:25

of little or no vegetation

play35:29

it happens in places let receive scanty

play35:32

rainfall

play35:34

for example the formation of sand dunes

play35:37

in the deserts

play35:42

the prevention of soil erosion is called

play35:45

soil conservation

play35:49

most methods of soil conservation aim to

play35:52

reduce the speed of running water and

play35:54

wind overland to reduce soil erosion

play35:59

one way to conserve soy in mountainous

play36:02

regions is Terrace farming

play36:06

this involves cutting terraces along the

play36:09

slope

play36:16

you

play36:49

other methods of preventing soil erosion

play36:51

include effective farming techniques

play36:56

in plane areas strip cropping can be

play37:00

used for soil conservation

play37:03

in this method strips of grass are

play37:06

allowed to stand between crops in large

play37:08

fields

play37:10

these strips of grass reduce the force

play37:13

of wind and thus prevent soil erosion

play37:18

this technique also prevents soil

play37:21

nutrients from depleting

play37:29

planting rose trees along farmland also

play37:33

helped break the force of wind and help

play37:36

in soil conservation

play37:39

such shelterbelts of trees when planted

play37:42

alone sand dunes help stabilize them and

play37:46

prevent the desert from extending into

play37:48

land available for cultivation
