Start here: why this chapter matters
In simple wordsLook around your room. The bottle of water, the fan, the book, the phone charger — and you yourself, reading. Each of these is useful to someone, so each is a resource. This first chapter of the Class 8 geography book teaches one way of seeing the world: as a store of things that people can use, make better, waste or save.
This is Chapter 1 of NCERT's Class 8 geography book Resource and Development (2024–25 reprint), book pp. 1–6 (6 PDF pages; QR code 0858CH01). It is a short chapter told through a family — Mona, Raju and their mother, Amma — with one comic strip, a list, glossary boxes and activity boxes. Its parts: what a resource is (utility and value); time and technology; types of resources — natural (renewable and non-renewable), human made and human; conserving resources and sustainable development, with a box of six principles; exercises, a couplet by Rahim and two ‘For Fun’ tasks. Because the chapter is short, we use six compact concept sections rather than padding it. The book is world-scale, not India-only; it has no maps, and we draw none. It gives almost no numbers, so the ‘numbers’ to remember are mostly counts and dates; any date beyond the book is marked †.
- How this chapter relates to UPSC, honestly: the chapter is the vocabulary layer — resource, renewable, stock, human resource, sustainable development — on which GS1 (distribution of resources), GS2 (human resource development) and GS3 (environment, conservation, circular economy) questions are built. UPSC does not ask this chapter's sentences; it asks questions that assume them.
- The senior version: jess101 (Class 10, Resources and Development) teaches the same idea with four bases of classification, Rio 1992, Agenda 21, resource planning, land use and soils — read it next; we do not repeat it here. Then legy206 (Planning and Sustainable Development), keec107 (Environment and Sustainable Development), keec104 (Human Capital Formation), legy103 (Human Development), legy205 (Mineral and Energy Resources), jess105 (Minerals and Energy Resources), kegy214 (Biodiversity and Conservation).
- In this book: next come hess402 (Land, Soil, Water, Natural Vegetation and Wildlife Resources), hess403 (Agriculture), hess404 (Industries) and hess405 (Human Resources), which takes this chapter's last type further. Class 7 and 8 History and Polity chapters are live (e.g. hess307, Public Facilities — water as a shared need).
- UPSC from this chapter: five questions whose core idea this chapter genuinely teaches — Prelims 2018 (human capital formation) and 2025 (circular economy); Mains GS1 2021 (uneven distribution of mineral oil), GS2 2023 (human resource development) and GS3 2019 (protecting traditional medical knowledge from patenting). List at the end.
| Word | What it means here |
|---|---|
| Resource | Anything that can be used to satisfy a need |
| Utility | Usability — the fact that a thing can be used; it is what makes an object or substance a resource |
| Value | Worth; a resource's use gives it value, which may or may not be economic (money) value |
| Patent | An exclusive legal right over an invention (the book's glossary says ‘any idea or invention’ — see trap) |
| Technology | The application of knowledge and skill in doing or making things (glossary; it adds ‘latest’) |
| Natural resource | Drawn from nature and used without much modification — air, water, soils, minerals |
| Renewable / non-renewable | Renewed or replenished quickly / a limited stock that takes ages to be replenished |
| Stock of a resource | The amount of a resource available for use (glossary) |
| Human made resource | A natural substance whose form people have changed — iron from ore, buildings, roads, vehicles; technology |
| Human resource | People — their number (quantity) and their mental and physical abilities |
| Human resource development | Improving the quality of people's skills so that they can create more resources |
| Resource conservation | Using resources carefully and giving them time to get renewed |
| Sustainable development | Using resources to meet present needs while also taking care of future generations |
Reading the chapter opener (page 1) and the page decorations
- Opener drawing (colour): a curved banner across the top shows a snow-capped volcano-like mountain, a lake or river, trees, a tall pink building and factory chimneys, with a person in a red shirt holding a basket in the foreground; the chapter number and the title ‘Resources’ sit beside it with a QR code (0858CH01). The point: nature (mountain, water, trees), things people make (buildings, factories) and people themselves — the chapter's three types of resources — in one picture.
- Page footers repeat a small mountain, buildings and a figure by the water: decoration with the same message.
At a glance — the six ideas to carry away
- Resource = anything that can be used to satisfy a need. Utility (usability) makes a thing a resource; use gives it value. Quantity is not a test.
- Value: economic (metals) or not (a beautiful landscape) — both satisfy needs; time can add economic value (a home remedy, if patented).
- Time and technology change substances into resources; people are the most important resource (fire → cooking; wheel → transport; hydro technology → power).
- Three types: natural (renewable — solar, wind unlimited; water, soil, forest can run short — and non-renewable: coal, petroleum, gas), human made (iron from ore, roads, machines, technology), human.
- Natural resources are spread unequally because terrain, climate and altitude differ. HRD = improving people's skills; education and health make people valuable.
- Conservation: use carefully, give time to renew. Sustainable development: balance present use and the future. Six principles; three duties; reduce, reuse, recycle.
1. What makes something a resource: utility and value
In simple wordsAn old steel spoon in a drawer and a seashell from a holiday are both ‘worth’ something. The spoon is useful every day and would fetch a few rupees; the shell is useless for eating but you would never sell it. Both are resources to you — one has money value, the other does not. And if one day a shop starts selling shells, yours suddenly has a price.
Mona and Raju help Amma clean the house: clothes, utensils, foodgrains, combs, a bottle of honey, books — each has a use, which is why each matters. Amma's definition: anything that can be used to satisfy a need is a resource. The water you drink, the electricity at home, the rickshaw home from school, the textbook, the vegetables in a snack — all are resources because they have been used: they have utility. Utility, or usability, is what makes an object or substance a resource. Things become resources only when they have value, and it is their use or utility that gives them value; all resources have some value. Value means worth. Some resources have economic value, some do not: metals may have economic value, a beautiful landscape may not — but both are important and satisfy human needs. Some resources can become economically valuable with time: a grandmother's home remedies have no commercial value today, but if a medical firm patented and sold them tomorrow, they could become economically valuable.
⤵ From thing to resource, in the book's order (p. 1)
A needthirst, light, getting home, learning, food
A thing that meets itwater, electricity, a rickshaw, a textbook, vegetables
Utilityit has been used — usability makes it a resource
Valueits use gives it worth; all resources have some value
Economic valuemetals; things bought and sold
No economic valuea beautiful landscape — still important, still meets a need
Reading the ‘Let's do’ box and the patent glossary (page 1)
- Let's do: list five resources you use at home and five in your classroom. The point: resources are everyday things, not only coal and oil (outline in the in-text section).
- Glossary — Patent: ‘the exclusive right over any idea or invention’. The point: a patent is how knowledge with no market price can acquire one. (On ‘any idea’, see the trap below.)
Beyond NCERT — traditional knowledge and patents (bare facts)
- India's patents are granted under the Patents Act, 1970; a patent lasts 20 years from the date of filing. Section 3 lists what is not an invention — for example, knowledge that is in effect traditional knowledge, or a mere new use of a known substance.
- The Traditional Knowledge Digital Library (TKDL), begun in 2001 by the CSIR with the ministry now called AYUSH, records traditional medical formulations so that patent examiners abroad can see they are not new.
- In 1997 a US patent on the use of turmeric for healing wounds was revoked after the CSIR showed the use was already known in India — the book's ‘grandmother's remedies’ in a real case.
NCERT details to read carefully — utility and value
- Utility makes a thing a resource; value comes from that utility. Exercise 2(i): quantity is the one that does not make a substance a resource.
- ‘Value’ is not only money: the book says some resources (a landscape) have no economic value and are still resources.
- Patent, ‘any idea’: patents protect inventions — new, inventive and useful products or processes — not bare ideas; copyright protects expression, not ideas either. Safe line: ‘a patent is an exclusive right over an invention for a limited period’.
- The home-remedy example is a hypothetical (‘if… tomorrow’), not a claim that such patents are routinely granted; in India, traditional knowledge as such is not patentable †.
2. Time, technology and people
In simple wordsA smartphone in 1950 would have been a useless glass brick — no network, no charger, no apps. The phone did not change its nature; time and technology caught up with it. The book says the same of the wind, the river and the rock: they wait, unchanged, until people know how to use them.
Time and technology are two important factors that can change substances into resources, and both are related to people's needs. People themselves are the most important resource: their ideas, knowledge, inventions and discoveries create more resources, and each discovery or invention leads to many others. The discovery of fire led to cooking and other processes; the invention of the wheel ultimately led to newer modes of transport; the technology to create hydroelectricity has turned the energy in fast-flowing water into an important resource. The glossary defines technology as the application of (the latest) knowledge and skill in doing or making things. A ‘For Fun’ question at the end makes the same point with wind on a high plateau in prehistoric times and again in the year 2138.
Reading the technology glossary and the ‘So I am a resource too!’ drawing (page 2)
- Glossary — Technology: the application of latest knowledge and skill in doing or making things.
- Drawing (colour): Amma, in a yellow sari, kneels and hugs a small girl; speech bubbles — the girl: ‘So I am a resource too!’; Amma: ‘A very valuable one!’ It sits beside the sentence that people are the most important resource. The point: the chapter counts the reader as a resource — the idea it returns to under human resources.
NCERT details to read carefully — time and technology
- The two factors named are time and technology — not ‘money and labour’. Class 10 (jess101) uses a different three-part test: technologically accessible, economically feasible, culturally acceptable. Do not mix the two lists.
- Technology as ‘latest’ knowledge (glossary): technology need not be the latest — a plough or a water wheel is technology too. Safe line: ‘technology is the application of knowledge and skill to doing or making things’.
- Fire was discovered; the wheel was invented — the book uses the two words deliberately.
3. Natural resources: renewable, non-renewable, and unequally spread
In simple wordsA well that refills every monsoon is like a salary: spend no more than comes in and it never runs dry. A box of gold coins buried by your great-grandparents is like savings: every coin you spend is gone for good. Renewable resources are the salary; non-renewable ones are the savings. And just as some families inherit more than others, some places on earth were simply dealt more coins.
Resources are generally classified into natural, human made and human. Natural resources are drawn from nature and used without much modification — the air we breathe, the water in rivers and lakes, soils, minerals. Many are free gifts of nature and can be used directly; sometimes tools and technology are needed to use them in the best way. They are broadly renewable or non-renewable. Renewable resources get renewed or replenished quickly. Some are unlimited and not affected by human activities, such as solar and wind energy; yet careless use of others — water, soil and forests — can affect their stock (the amount available for use). Water seems unlimited, but shortages and the drying up of natural water sources are a major problem in many parts of the world. Non-renewable resources have a limited stock: once exhausted, they may take thousands of years to be renewed — far longer than human life spans — so they are considered non-renewable: coal, petroleum and natural gas. The distribution of natural resources depends on physical factors like terrain, climate and altitude; because these differ so much over the earth, resources are distributed unequally.
| The book's natural resources, sorted | Renewable or not (book) | What can go wrong | Note for answers |
|---|---|---|---|
| Solar energy, wind energy | renewable, unlimited | not affected by human use (book) | ‘inexhaustible’ or ‘flow’ resources in senior books † |
| Water | renewable | careless use; shortages and drying-up of sources in many parts of the world | renewable ≠ unlimited: a stock can fall |
| Soil | renewable | careless use affects its stock | soil forms very slowly (jess101, hess402) |
| Forests | renewable | careless use affects their stock | renewable and biotic (jess101) |
| Coal, petroleum, natural gas | non-renewable | limited stock; once exhausted, gone for human time spans | fossil fuels formed over millions of years † |
| Minerals | listed as natural (book) | — | metals can be recycled; fuels cannot (jess101) |
| Unequal distribution: the book's three factors with world examples (no map) | What differs | An example of the effect (ours, general) |
|---|---|---|
| Terrain | mountains, plateaus, plains, deserts | level river plains (the Ganga, the Nile, the Mississippi) carry deep soils and dense farming; steep slopes carry little |
| Climate | rain, sunshine, temperature, wind | deserts receive strong sun but little water; wet tropics have water and forests; windy coasts and plateaus suit wind power |
| Altitude | height above sea level | high mountains are cold, with thin soils and short seasons, but their snow and glaciers feed rivers below |
| Geology (implied; † not one of the book's three) | the rocks beneath | fossil fuels and many minerals lie in particular rock basins, so a few regions hold most of them (Mains GS1 2021 on mineral oil) |
Reading the stock glossary and the ‘renewable overuse’ box (page 3)
- Glossary — Stock of resource: the amount of resources available for use. The point: ‘renewable’ is about the rate of renewal; ‘stock’ is how much is there now — the two together decide whether a resource runs short.
- Let's do: think of a few renewable resources and say how overuse may affect their stock. The point: renewable is not the same as limitless (outline in the in-text section).
NCERT details to read carefully — natural resources
- ‘Free gifts of nature’ (this book, p. 2) against ‘resources are not free gifts of nature’ (Class 10, jess101, which calls them a function of human activities). Both are NCERT. Safe line: ‘many natural resources are provided by nature, but they become resources only through human use, knowledge and technology’.
- ‘Thousands of years’ for non-renewables understates fossil fuels, which formed over millions of years †. Safe line: ‘non-renewable resources cannot be replenished within human time scales’.
- Renewable ≠ unlimited: only some renewables (solar, wind) are unlimited; water, soil and forests can be depleted.
- Exercise 2(iii): non-renewable = limited stock. ‘Derived from non-living things’ is wrong — that is abiotic, and abiotic resources such as solar energy, wind and water are renewable.
- The book's factors for distribution are terrain, climate and altitude — learn the three by name for exercise 1(i).
4. Human made resources
In simple wordsFlour in a jar is a natural product; a loaf of bread is something people made from it. Iron ore in a hill is natural; the bicycle in your shed is human made. Every human made resource starts as a natural one — people add knowledge and work, and the thing changes form.
Sometimes natural substances become resources only when their original form has been changed. Iron ore was not a resource until people learnt to extract iron from it. People use natural resources to make buildings, bridges, roads, machinery and vehicles — human made resources. Technology is also a human made resource. Mona sums it up: people like us use natural resources to make human made resources. Exercise 2(ii) tests the idea: of medicines to treat cancer, spring water and tropical forests, only the medicines are human made.
⤵ From ore to bridge: a natural resource becomes human made (p. 3)
Natural substanceiron ore in the ground — not yet a resource while no one could use it
Knowledge and technologypeople learn to extract iron from the ore
Changed formiron (and steel †) — the original form has changed
Thingsbuildings, bridges, roads, machinery, vehicles
Know-howtechnology itself is a human made resource
| Which kind is it? — exercise-style sorting | Kind (book's scheme) | Why |
|---|---|---|
| Medicines to treat cancer | human made | made by people from natural substances (exercise 2(ii)) |
| Spring water | natural (renewable) | used without much modification |
| Tropical forests | natural (renewable) | drawn from nature |
| A bridge, a road, a tractor | human made | natural materials (stone, iron, petroleum) changed in form |
| Technology | human made | the book says so explicitly |
| A doctor's medical knowledge | human | a skill held by a person (Amma's list) |
Reading the ‘Let's do’ box on human made resources (page 3)
- Let's do: list five human made resources you can observe around you. The point: nearly everything in a built room — walls, wires, furniture, the fan — began as a natural resource (outline in the in-text section).
NCERT details to read carefully — human made resources
- Iron ore is a natural resource (a mineral); iron extracted from it and the things made of it are human made. The book's sentence ‘iron ore was not a resource until…’ is about time and technology, not a claim that ore is human made. Amma's list puts ‘iron ore’ and ‘coal deposits’ among natural things.
- Technology counts as a human made resource; skill and knowledge in a person count as human resources.
- Exercise 2(ii): the answer is (a) medicines to treat cancer.
5. Human resources and human resource development
In simple wordsTwo teams get the same football and the same field. One team has trained for a year; the other has never played. The ball and field are the same ‘resources’ — the trained players get far more out of them. People are the resource that decides how well every other resource is used, and training, schooling and good health are how that resource grows.
People can make the best use of nature to create more resources when they have the knowledge, skill and technology to do so. That is why human beings are a special resource: people are human resources. Education and health help make people a valuable resource. Improving the quality of people's skills so that they can create more resources is called human resource development. A ‘Do you know?’ box adds that ‘human resource’ refers to the number (quantity) and the abilities (mental and physical) of people, and notes that there are differing views on treating humans as a resource — while holding that it is human skill that turns physical material into a valuable resource. A comic strip shows a scientist who reads that crops have been ruined by drought, works out a solution, and is thanked by farmers who credit knowledge, education and skill; a ‘Read and Ponder’ note says humans are interdependent — farmers grow food for everyone, and scientists suggest ways to fight farm problems and raise production.
⤵ The comic strip (p. 3): how knowledge becomes a resource for others
A problema newspaper: crops ruined due to drought
A trained minda scientist asks whether she can find a solution
Knowledge appliedin her laboratory she finds one — ‘that's it!’
Shared benefitfarmers thank her: it is all thanks to knowledge, education and skill
The lessonhumans are interdependent; skill turns material into a valuable resource
Reading the comic strip, ‘Read and Ponder’ and the ‘Do you know?’ box (page 3)
- Comic strip (colour, three panels): a woman scientist at a laboratory bench with test tubes reads a newspaper — bubble: ‘Crops ruined due to drought’. ‘Can I find a solution?’; a light bulb glows above her; in the next panel, ‘that's it!’; in the last, she stands among a group of village men and women in turbans and saris, who say it is all thanks to knowledge, education and skill that a solution was found.
- Read and Ponder (shaded): humans are interdependent — farmers provide food grains for everyone; scientists suggest means to combat farm problems and improve production.
- Do you know?: human resource = number and abilities of people; differing views exist on treating humans as a resource, but human skill transforms physical material into a valuable resource.
- The point: knowledge held by one person becomes a resource for many — the case for investing in education and research.
| Should people be called a ‘resource’? — positions side by side (book row, plus † rows; no position endorsed) | Who | Position |
|---|---|---|
| People as a resource | NCERT (pp. 2–4) | people are the most important resource; their skills turn material into valuable resources, so education and health are investments |
| ‘Differing views’ acknowledged | NCERT, ‘Do you know?’ (p. 3) | there are differing views on treating humans as a resource; the book does not set them out |
| Human capital † | economists of human capital (keec104) | spending on education, training and health raises productivity and earnings, like investment in machines |
| People as ends, not means † | the human development approach, e.g. the UNDP Human Development Reports since 1990 (legy103) | development is about widening people's choices and capabilities for their own sake, not only about using them as inputs to output |
Beyond NCERT — bare facts
- The UNDP's first Human Development Report came out in 1990; its Human Development Index combines health (life expectancy), education and income (legy103).
- India's Ministry of Human Resource Development was renamed the Ministry of Education in 2020, alongside the National Education Policy 2020.
- Human capital formation (keec104) is the senior name for HRD: raising the knowledge, skills and health of people — UPSC asked its meaning in 2018.
- This book's own chapter 5 (hess405, Human Resources) covers population, its distribution and composition.
NCERT details to read carefully — human resources
- Human resource has two parts: number (quantity) and abilities (quality — mental and physical). A large population alone is not a strong human resource.
- HRD = improving the quality of people's skills so they can create more resources; the inputs the book names are education and health.
- Exercise 1(iii), ‘why are human resources important?’: because people's knowledge, skill and technology turn natural substances into resources and create more — not simply because there are many people.
6. Conserving resources and sustainable development
In simple wordsA family orchard can feed the family forever if each year they pick the fruit and leave the trees. Cut the trees for one big sale and there is cash this year and nothing for the grandchildren. Sustainable development is the rule ‘pick the fruit, keep the trees’ — applied to water, soil, forests, fuels and the whole earth.
Mona dreams that all the water on earth has dried up and all the trees are cut: no shade, nothing to eat or drink, people roaming desperately. Amma says it can happen: if we are careless, even renewable resources can become very scarce, and non-renewable ones can definitely be exhausted. Resource conservation is using resources carefully and giving them time to get renewed. Sustainable development is balancing the need to use resources with conserving them for the future; the glossary puts it as using resources so that, besides meeting present requirements, we take care of future generations. Each person can help by reducing consumption, recycling and reusing things. The children make packets and shopping bags from old newspapers and discarded clothes and baskets from bamboo sticks to give to families; Jessy will not waste paper, because many trees are cut to make it; Mustafa will save electricity, which ‘comes from water and coal’; Asha will not waste water. The future of the planet, the book says, depends on maintaining nature's life-support system, so it is our duty to ensure that all uses of renewable resources are sustainable, that the diversity of life is conserved, and that damage to natural environmental systems is minimised. A side box lists six principles of sustainable development.
⤵ From Mona's nightmare to sustainable development (pp. 4–5)
The fearwater dried up, trees cut down — no shade, food or drink
Amma's warningcareless use makes even renewables scarce; non-renewables can be exhausted
Resource conservationuse carefully; give resources time to renew
Each personreduce consumption, reuse, recycle — bags, baskets, saving paper, power, water
Society's dutysustainable use of renewables; conserve the diversity of life; minimise damage to natural systems
Sustainable developmentmeet present needs while taking care of future generations
| The book's six principles (p. 5) | In plain words | Where it leads in senior books |
|---|---|---|
| Respect and care for all forms of life | other species matter, not only people | biodiversity, kegy214 |
| Improve the quality of human life | development must make lives better | human development, legy103 |
| Conserve the earth's vitality and diversity | keep ecosystems working and varied | kegy214, keec107 |
| Minimise the depletion of natural resources | use less, waste less, especially what cannot renew | minerals and energy, legy205, jess105 |
| Change personal attitude and practices towards the environment | habits — the children's promises | keec107 |
| Enable communities to care for their own environment | local people manage local resources | local Agenda 21, jess101; legy206 |
Reading Mona's nightmare, the children's drawing and the sustainable development glossary (page 4)
- Drawing 1 (colour): a girl sits up in bed, frightened, under a dream-cloud of cracked yellow earth with dead trees and the skeletons of animals; a lamp and slippers by the bed. The point: the cost of exhausting resources, made vivid.
- Drawing 2 (colour): four children at work — one weaves a basket from bamboo, one stitches a bag from colourful cloth, one turns off a dripping tap over a bucket, one reaches to switch off a light at a switchboard. The point: conservation is done in daily acts — reuse, saving water, saving electricity.
- Glossary — Sustainable development: carefully using resources so that, besides meeting the requirements of the present, we also take care of future generations.
Reading the ‘Some Principles of Sustainable Development’ box (page 5)
- A shaded box of six bullet points, listed in the table above. The book gives no source. The point: sustainability is about life, people's well-being, ecosystems, resources, habits and communities together — not only about saving fuel.
Beyond NCERT — dated facts
- The best-known definition of sustainable development is from the Brundtland Commission's report Our Common Future (1987): development that meets the needs of the present without compromising the ability of future generations to meet their own needs (jess101, legy206).
- The six principles closely match those of Caring for the Earth: A Strategy for Sustainable Living (1991, by IUCN, UNEP and WWF), which set out nine; the others include keeping within the earth's carrying capacity. The book does not name its source — cite the principles as NCERT's.
- The 17 Sustainable Development Goals were adopted by the UN in 2015 for 2030; SDG 12 is responsible consumption and production — the ‘reduce, reuse, recycle’ idea at world scale.
- A circular economy keeps materials in use through reuse, repair and recycling, cutting both raw-material use and waste (UPSC Prelims 2025).
NCERT details to read carefully — conservation
- Resource conservation (use carefully, give time to renew) and sustainable development (balance present use and future needs) are two separate definitions in the book — exercises 1(ii) and 1(iv) ask them separately.
- ‘Electricity comes from water and coal’ (Mustafa): true of hydro and thermal power, but electricity also comes from solar, wind, nuclear and gas †. Safe line: ‘much of India's electricity comes from coal, with hydro and other sources’.
- The three duties are sustainable use of renewables, conserving the diversity of life, minimising damage to natural systems — they are not the same list as the six principles.
- The Brundtland wording (1987) is the standard citation; the book's glossary paraphrases it without naming it.
In-text questions and activities — answer outlines
Every ‘Let's do’, activity and question in the text, in page order. (‘For Fun’ sits with the exercises.)
(p. 1) Let's do: List out five resources you use in your home and five you use in your classroom.
Home: water, electricity, cooking gas (LPG), food grains, a bed or clothes. Classroom: textbooks, the blackboard and chalk, desks and benches, the fan or light, the teacher's knowledge. Note which are natural (water), human made (desks, electricity supply) and human (the teacher).
(p. 2) Activity: Circle those resources from Amma's list that are regarded as having no commercial value.
Usually circled: intelligence, beautiful scenery, clean environment, old folk songs, good weather, resourcefulness, a good singing voice, grandmother's home remedies, affection from friends and family. Have commercial value: cotton cloth, iron ore, coal deposits, agricultural land, medicinal plants, medical knowledge (a doctor's fees). Discuss the grey areas — a singing voice can earn money; folk songs can be recorded and sold; scenery draws tourists; home remedies could be patented (the book's own point that value changes with time).
(p. 3) Let's do: Think of a few renewable resources and mention how their stock may get affected by overuse.
Groundwater: pumping faster than rain recharges it lowers the water table, wells dry up. Forests: cutting faster than regrowth shrinks forest cover and wildlife. Soil: over-farming, over-grazing and bare land lead to erosion and loss of fertility. Fish: over-fishing catches fish before they breed. Rivers: diverting and polluting them leaves too little clean water downstream. The rule: use beyond the rate of renewal reduces the stock.
(p. 3) Let's do: Make a list of five human made resources that you can observe around you.
A school building, a road or bridge, a bicycle or bus, a computer or phone, an electric fan; also a dam, a hand pump, a tube light. Each is made by changing the form of natural resources (clay, iron, petroleum, sand).
(p. 3) Read and Ponder: Humans are interdependent on each other. Farmers provide food grains for everyone. Scientists suggest means to combat agricultural problems and improve farm production.
Points to ponder: no one is self-sufficient — the farmer needs the scientist's seeds and advice, the scientist needs the farmer's food; knowledge is a resource that helps many at once; so educating and keeping people healthy (HRD) benefits everyone, not only the person educated.
(p. 5) These are some of the things Mona, Raju and their friends did. What about you? How are you going to help in conserving resources?
Examples: turn off taps and lights when not in use; carry a cloth bag; use both sides of paper; reuse jars and boxes; repair instead of throwing away; separate wet and dry waste for recycling; walk, cycle or use public transport; plant and care for a tree; harvest rainwater at school. Sort them into reduce, reuse and recycle.
Exercises (pages 5–6) — answer outlines
Exercise 1 has 4 short answers, exercise 2 has 3 multiple-choice items, exercise 3 is an activity on a couplet by Rahim, and there are two ‘For Fun’ tasks. Try first, then open.
1(i). Why are resources distributed unequally over the earth?
Because the distribution of natural resources depends on physical factors — terrain, climate and altitude — and these differ greatly from place to place. Example: level river plains with water and deep soils suit farming; deserts have sun but little water; coal and petroleum occur only in certain rock basins.
1(ii). What is resource conservation?
Using resources carefully and giving them time to get renewed — for example, saving water and electricity, not wasting paper, reusing and recycling things — so that renewable resources do not become scarce and non-renewable ones are not exhausted.
1(iii). Why are human resources important?
People are the most important resource: with knowledge, skill and technology they make the best use of nature and turn natural substances into valuable resources; their ideas, inventions and discoveries create more resources (fire, the wheel, hydroelectricity). Education and health make them more valuable — human resource development.
1(iv). What is sustainable development?
Carefully using resources so that, besides meeting the needs of the present, we also take care of the needs of future generations — balancing the use of resources with conserving them. (Standard wording †: the Brundtland Report, 1987.)
2(i). Which one of the following does NOT make substance a resource? (a) utility (b) value (c) quantity
(c) quantity. Utility and the value it gives make a thing a resource; how much of it there is does not.
2(ii). Which one of the following is a human made resource? (a) medicines to treat cancer (b) spring water (c) tropical forests
(a) medicines to treat cancer — made by changing natural substances. Spring water and tropical forests are natural resources.
2(iii). Complete the statement. Non-renewable resources are (a) those which have limited stock (b) made by human beings (c) derived from non-living things
(a) those which have limited stock. (b) describes human made resources; (c) describes abiotic resources, many of which (sunlight, wind, water) are renewable.
3. Activity: ‘Rahiman paani raakhiye…’ — What kind of resource is the poet referring to? Write in 100 words what would happen if this resource disappeared.
The resource is water — a natural, renewable resource whose stock can still run out. Outline for 100 words: without water there would be no drinking water, so people and animals would die of thirst; crops would fail and food would run out; forests would dry and wildlife vanish; no hydroelectricity, no factories, no cleaning — diseases would spread; rivers and lakes would turn to dust (Mona's nightmare). End: every drop is precious, so conserve it. (On the couplet, see the trap below: in it ‘paani’ also means lustre and honour.)
For Fun 1. You live in prehistoric times on a high windy plateau: what uses could you put the fast winds to? Can you call the wind a resource? Now imagine the same place in 2138: can you use the winds? How? Why is wind an important resource now?
Prehistoric: winnowing grain (separating husk), drying food, hides and clothes, spreading or fanning fire, flying kites, sensing weather — yes, it is a resource because it has utility. In 2138: wind turbines for electricity, windmills to pump water or grind grain, sailing; it is important because it is renewable and unlimited, causes little pollution, and fossil fuels are limited. The point: time and technology change what a resource can do.
For Fun 2. Pick up a stone, a leaf, a paper straw and a twig. Think of how you can use these as resources (the book fills in a stone table as an example).
The book's stone: play stapu (toy), paper-weight, crushing spices, opening a bottle (tools), decoration, catapult (weapon). Leaf (ours): a plate (tool), a fan, compost or manure, a medicine (e.g. tulsi), a whistle (toy), decoration, fodder. Paper straw: drinking, a pea-shooter (toy), craft and models, a plant label. Twig: a toothbrush (neem), firewood, a support stake for a plant, a writing stick in sand, a toy or puppet frame. Each use gives the object utility — so it becomes a resource.
Reading the Rahim couplet activity and the For Fun tables (pages 5–6)
- Activity box: a four-line Hindi couplet by Abdur Rahim Khankhana, called one of the nine gems of Akbar's court, with the book's English gloss that without water there is nothing, and that without water ‘pearl, swan and dough’ cannot exist; the task is to name the resource and write 100 words on its loss.
- For Fun tables: a two-column table headed ‘You can use a stone…’ / ‘Use/Utility’ with six filled rows (stapu — toy; paper-weight — tool; crushing spices — tool; decorating — decoration piece; opening a bottle — tool; catapult — weapon) and two blank rows; a second, empty table for a leaf, with drawings of a stone and a leaf. The point: utility makes a resource, and one object can have many utilities.
Keys and slips to handle with care
- Exercise keys: 2(i) (c) quantity; 2(ii) (a) medicines; 2(iii) (a) limited stock.
- The Rahim gloss: in the couplet moti, manus, choon, ‘manus’ is usually read as ‘human being’, not ‘swan’, and ‘paani’ carries three senses — lustre for the pearl, honour for a person, water for the flour or lime (‘choon’). The book's ‘swan’ looks like a slip. Safe line: ‘Rahim's couplet plays on paani as lustre, honour and water’.
- Rahim †: Abdul Rahim Khan-i-Khanan (1556–1627), son of Bairam Khan, poet and commander under Akbar. The ‘nine gems’ (navaratnas) list is a later tradition — say ‘traditionally counted among Akbar's navaratnas’.
- Stored UPSC keys: of the five linked questions, two are Prelims; the 2018 key (c) and the 2025 key (a) agree with standard answers; none of the pending key issues applies.

One-liners
- Anything that can be used to satisfy a need is a resource.
- Utility gives a thing value; value need not be money.
- Time and technology turn substances into resources.
- People are the most important resource.
- Renewable does not mean unlimited: water, soil and forests can run short.
- Non-renewable resources have a limited stock that cannot be replaced in human time.
- Terrain, climate and altitude make the spread of resources unequal.
- Human made resources are natural substances changed in form; technology is one too.
- Education and health make people a valuable resource.
- Sustainable development balances present use with the needs of future generations.
Traps to avoid
- Quantity does not make a thing a resource; utility and value do.
- This book calls many natural resources ‘free gifts of nature’; Class 10 says resources are not free gifts — both are NCERT.
- Fossil fuels formed over millions of years, not the book's ‘thousands’.
- ‘Derived from non-living things’ describes abiotic resources, not non-renewable ones.
- Iron ore is a natural resource; iron and what is made from it are human made.
- A patent protects an invention for a limited time, not ‘any idea’.
- Human resource means number and abilities, not population size alone.
- Resource conservation and sustainable development are defined separately in the book.
- In Rahim's couplet ‘manus’ is usually read as a human being, not a swan.
- Class 8's test is time and technology; Class 10's is technological, economic and cultural.
How to strategise
Prelims — what UPSC asks
- From this chapter: the meaning of human capital formation — raising knowledge, skills and capacities (2018); and the circular economy — less raw material, less waste, hence lower emissions (2025). Both rest on this chapter's HRD and reduce–reuse–recycle ideas.
- Elsewhere: the Brundtland definition and carrying capacity (2010) sits on legy206, kesy203 and keec107; Rio, Agenda 21 and the Club of Rome (2010, 2016) on jess101 and legy206; the IUCN Red Data Book (2011) on kegy214. Learn the vocabulary here, the facts there.
Mains — where it appears and how to answer
- From this chapter: GS1 2021 (multi-dimensional implications of the uneven distribution of mineral oil) — start from why resources are unevenly spread and that oil is non-renewable, then legy205 for the facts; GS2 2023 (inadequate attention to human resource development) — HRD as education and health, with keec104; GS3 2019 (protecting traditional medical knowledge from patenting) — the book's home-remedy example, then TKDL and the Patents Act as dated facts.
- Elsewhere: intra- and inter-generational equity (GS3 2020) and carrying capacity (GS3 2019) on legy206 and keec107; demographic dividend (GS2 2016, GS3 2014) on legy201 and keec104.
- Keep answers neutral: give data with year and source; set out positions on ‘people as a resource’, patents on traditional knowledge, and growth versus conservation as attributed views side by side; no present-day political commentary.
