Ravi was sitting near the window in class. Outside, he saw the sun shining ☀️, the wind moving the leaves 🍃, and a water tanker passing by 🚛.
He asked his teacher:
“Ma’am, are all these things resources?”
The teacher smiled and said:
“Only if we can use them wisely.”
Let’s learn what she meant…

📌 Resources
🔍 What is a Resource?
A resource is anything in our environment that can help us. But — just being there is not enough!
It should also be:
| Criteria | What it Means 🧠 | Example in India 🇮🇳 |
|---|---|---|
| Technologically Accessible | We must have the tools to use it | Using windmills in Tamil Nadu |
| Economically Feasible | It shouldn’t cost too much | Water from nearby rivers for farming |
| Culturally Acceptable | People should be okay using it | Using cows for milk but not for meat in many parts of India |
➡️ So, a tree 🌳 becomes a resource only when:
- we know how to cut and use it,
- it’s worth cutting,
- and it’s okay for the community to use.
💬 Example!
🔹 A rock is just a rock until we cut it and use it for building homes.
🔹 Sunlight is just light until we create solar panels to make electricity.
🔹 Water is just flowing until we use it to grow crops in Punjab 🌾.
🔁 Transformation of Resources
📦 Real-life Comparisons
| 🪵 Wood from a Tree | 💡 Becomes furniture with tools |
| ☀️ Sunlight | 💡 Becomes electricity using panels |
| 🧱 Clay | 🏠 Becomes bricks for homes |
| 📱 Your old phone | 💰 Becomes e-waste or reused |
📌 Moral?
We turn “things” into “resources” using our brains 🧠 and tools 🛠️
Let’s look at how things become resources.
👉 This process involves:
| Part | Role |
|---|---|
| Nature 🌍 | Gives us raw materials like land, water |
| Technology 🛠️ | Helps us to use nature’s gifts |
| Institutions 🏛️ | Create rules & systems to manage resources |
🧠 Human beings are the center of it all. We connect everything!
👨🔬 Real-Life Example:
Let’s take coal 🪨:
- Nature gave us coal deep inside the earth.
- Humans built machines to dig it out (technology).
- Governments make policies about where, when, and how to use it (institutions).
🤔 Are Resources Free Gifts of Nature?
Many people say – “Nature gives us everything.”
But here’s the truth bomb 💣:
“Resources are not free gifts.
They are made by human effort + knowledge.”
Without farmers, engineers, or scientists — coal stays underground, rivers remain unused, and wind keeps blowing — uselessly.
👨🌾 Human beings are not just users — they are resource makers.

- d) A is false but R is true.
✍️ Short Answer
Q: Why are humans considered an important part of resources?
A: Because they understand, change, and use natural things with the help of knowledge and tools.
🧠 Connect the Dots
| Concept | Connected To | Why They’re Connected 🤝 |
|---|---|---|
| Resource | Technology | Technology helps use the resource |
| Human Beings | Institutions | Humans create institutions to manage resources |
| Nature | Raw Materials | Nature gives us the base materials |
Without human effort, nothing is truly a resource. Everything is just nature’s material.
✨ In Short
Resources are not free gifts.
They are created when humans use technology, knowledge, and rules to turn nature’s materials into useful things
🧭 Classification of Resources
“Sorting Things, Just Like Mom Does!”
Have you seen how your mom organizes the kitchen?
- Fruits 🍎 in one basket
- Masalas in another 🧂
- Cooked food separate from raw ingredients 🍛
She classifies everything to make it easy to find and use.
🌏 Just like that, geographers classify resources to better understand and manage them.
Let’s explore how we sort the resources of India 🇮🇳!
📦 (a) On the Basis of Origin – Biotic and Abiotic
| Type | What it Means in Simple Words | Examples from India |
|---|---|---|
| 🐄 Biotic | Living or once-living things | Plants 🌿, Animals 🐃, Humans 👨🌾 |
| 🪨 Abiotic | Non-living things | Soil, Water, Air, Minerals 🛢️ |
🧠 Tip to Remember:
“Bio” means life. So biotic = life-based.
🔁 (b) On the Basis of Exhaustibility – Renewable and Non-renewable
| Type | Can We Use It Again? | Time to Refill | Examples in India |
|---|---|---|---|
| ♻️ Renewable | Yes | Quickly | Sunlight ☀️, Wind 🌬️, Water 💧 |
| 🚫 Non-renewable | No (or very slow) | Takes millions of years | Coal, Petroleum, Natural Gas 🛢️ |
💡 Think of renewable as your mobile recharge — comes back again.
Non-renewable is like a one-time-use battery 🔋.
🧍 (c) On the Basis of Ownership – Individual, Community, National, International
| Type | Who Owns It? | Example (India 🇮🇳) |
|---|---|---|
| 👤 Individual | One person or family | A farmer’s land in Punjab |
| 👥 Community | A group or village | Village pond in Odisha |
| 🏢 National | Country or Government | Indian roads, forests, rivers |
| 🌍 International | Owned by all countries | High seas, Antarctica, air above 92 km |
🗝️ Fun Fact:
National resources are like roads — they may be outside your house, but they belong to the government.
🚀 (d) On the Basis of Status of Development – Potential, Developed, Stock, Reserves
| Type | What It Means | Example in India |
|---|---|---|
| 🌱 Potential | We can use it, but haven’t yet | Wind energy in Rajasthan desert 🌬️ |
| 🛠️ Developed | We are using it fully now | Coal mines in Jharkhand 🏭 |
| 📦 Stock | We have it, but can’t use it (no tech) | Hydrogen from ocean 🌊 |
| 🛑 Reserves | Part of stock, but we are saving it | Reserved coal for future energy needs 🏞️ |
🧠 Tip:
Think of stock as money in your bank, but you forgot your ATM pin 😅.
Reserves are like emergency money saved for later.
🎯 Questions Time!
✅ MCQs
- Which is an abiotic resource?
a) Cow
b) Tree
c) Soil
d) Fish
Answer: c) Soil - What kind of resource is coal?
a) Renewable and abiotic
b) Non-renewable and biotic
c) Non-renewable and abiotic
d) Renewable and biotic
Answer: c) Non-renewable and abiotic
❓ Assertion and Reason
Assertion (A): Sunlight is a renewable resource.
Reason (R): It gets used up and cannot be replaced.
- a) A and R both are true, R explains A
- b) A is true, R is false ✅
- c) A is false, R is true
- d) Both are false
✍️ Short Answer
Q: What is the difference between potential and developed resources?
A: Potential resources can be used but are not used yet. Developed resources are already in use.
🔗 Connect the Dots
| Concept | Connected With | Why They’re Connected 🌐 |
|---|---|---|
| Biotic | Renewable | Most living things renew naturally |
| Abiotic | Non-renewable | Minerals like coal take ages to form |
| Ownership | Use of resource | Who owns it decides how it’s used |
| Stock | Technology | We can’t use it without tech |
✨ In Short
Resources can be classified based on:
- 🌿 Origin (biotic/abiotic)
- ♻️ Use limit (renewable/non-renewable)
- 👥 Ownership (individual to international)
- 🚀 Development stage (potential, stock, etc.)
🌱 Development of Resources
“A Birthday Cake That Went Wrong…”
Imagine this:
It’s your friend’s birthday. A big, yummy cake 🎂 is placed on the table. Everyone is happy.
But… only 2 people eat almost the entire cake, and the rest get just crumbs. 😟
The party turns sad.
The same thing happens with resources on our Earth 🌍 when some people take too much, and others get nothing.
Let’s understand why and how we must change this.
🔍 What Are Resources For?
Resources help us:
| 🧍♂️ Purpose | 💡 Example (India) |
|---|---|
| Survival | Water 💧, air 🌬️, food 🌾 |
| Better life quality | Electricity ⚡, roads 🛣️, internet 📶 |
But people once thought:
“Resources are free gifts from nature. Let’s use as much as we want!”
🎯 WRONG IDEA!
❌ What Happened When People Misused Resources?
😬 Problem #1: Greed of a Few = Depletion
- Some people used too many resources
- 🌾 Forests were cut down
- 🛢️ Oil was overused
- 🪨 Minerals were mined too much
👉 Resources began disappearing.
💰 Problem #2: Rich Got Richer
- A few people or countries took control of most resources
- 🌍 Others got very little
- This created two groups:
| Group Name | What It Means |
|---|---|
| 🧥 Haves | People who have resources |
| 🚫 Have-nots | People who don’t have any |
Just like in some cities, slums are right next to luxury flats — unequal life 😔
🌏 Problem #3: Environment in Danger
Because of using too much:
| 🌪️ Issue | What It Means |
|---|---|
| 🌡️ Global warming | Earth is heating up |
| 🧴 Ozone layer depletion | UV rays are entering due to damage |
| 🛢️ Pollution | Water, air, and soil getting dirty |
| 🏜️ Land degradation | Good soil turning into wasteland |
This is not a future problem — it’s already happening in places like Delhi (pollution) and Rajasthan (desertification).
✋ Why Do We Need Equitable Distribution?
👉 “Equitable” means fair — not equal, but fair for all.
If resources are shared fairly, then:
✅ Everyone gets to live a good life
✅ There is peace between countries and people
✅ No one goes hungry or homeless
✅ Earth survives longer 🌍
🧠 Sustainable Development: The Magic Formula
“Use the resources wisely today,
so they are still there tomorrow.”
This is called:
🎯 Sustainable Development = Using smartly + Saving wisely
Just like you don’t finish all your mobile data on Day 1 of your plan 😅

a) Boys vs Girls
b) Rich vs Poor
c) Educated vs Uneducated
d) Old vs Young
✅ Answer: b) Rich vs Poor
❓ Assertion and Reason
Assertion (A): Only rich countries should use more resources.
Reason (R): They have more money.
a) Both A and R are true
b) A is true, R is false
c) A is false, R is true
✅ d) Both A and R are false
✍️ Short Answer
Q: Why is sustainable development important?
A: Because it helps protect resources for the future, and keeps the Earth safe for all living beings.
🔗 Connect the Dots
| Concept | Connects With | Why They’re Connected 🔗 |
|---|---|---|
| Greed | Depletion | Too much use leads to loss |
| Inequality | Ownership | Unequal use = social division |
| Overuse | Pollution, global warming | Overuse causes ecological problems |
| Fair Sharing | Global peace | Sharing brings peace and balance |
| Sustainability | Development | Smart use = long-term growth |
✨ In Short
Resource misuse leads to depletion, inequality, and ecological problems.
The only solution is sustainable development — use, save, and share wisely! 🌍
🌿 Sustainable Development
👣 + 💚 = A Better Future
“Using Without Losing!”
Imagine your mom gives you a big box of chocolates 🍫 for a week.
If you eat all of them on Day 1, what will happen?
— No chocolates for the next 6 days. 😩
But if you eat wisely, one per day… you’ll enjoy all week!
That’s exactly what we mean by Sustainable Development —
👉 Using resources wisely today, so that they’re still available tomorrow 🌍✨.

📊 RESOURCE PLANNING
“Use Wisely. Share Fairly. Plan Smartly.”
“What If Your Tiffin Box Had Only Rice?”
Imagine opening your tiffin box during lunch break and finding only rice 🍚, no sabzi, no roti.
Your friend opens his and has everything — roti, curry, rice, dessert! 🍛🍪
Wouldn’t it be better if both of you shared and balanced the food?
That’s exactly why resource planning is needed — because some places have too much, while some have too little.
🤔 What is Resource Planning?
Resource planning means thinking ahead and using resources in a smart and fair way.
So that no place suffers, and no place wastes.
It’s especially important in a country like India, which is full of diversity — in people, places, and resources!
📍 Why Is Resource Planning Needed in India?
India is large and full of varied landscapes — some places have a lot of one type of resource but lack others.
Let’s see 👇
| 🗺️ Region/State | ✅ Rich In | ❌ Lacks In |
|---|---|---|
| Jharkhand, Chhattisgarh, MP | Minerals, coal 🪨🔥 | Infrastructure, water |
| Arunachal Pradesh | Water 💧 | Roads, bridges, electricity |
| Rajasthan | Sun & wind 🌞💨 | Water |
| Ladakh | Culture 🏔️ | Water, minerals, roads 🛣️ |
🌍 So, planning helps:
- 🚛 Move resources where they are needed
- 🔧 Develop new resources
- 🏞️ Maintain balance between nature and needs
🧭 Levels of Resource Planning
Resource planning should happen at all levels – just like a school, home, and city all need planning.
| 🏢 Level | 🧠 What it means |
|---|---|
| National | Planning for whole India (by central govt) 🇮🇳 |
| State | Planning in each state like Gujarat, Kerala 🗺️ |
| Regional | Planning for a zone – like North-East, Marathwada 🌄 |
| Local | Planning for village, town, or city 🏘️ |
🧠 Questions Time!
✅ MCQs
- Why is resource planning needed in India?
a) Because resources are equal everywhere
b) Because all regions are poor
c) Because resources are unevenly distributed ✅
d) Because no one uses resources - Which state is rich in water but poor in infrastructure?
a) Rajasthan
b) Jharkhand
c) Arunachal Pradesh ✅
d) Gujarat
❓ Assertion and Reason
Assertion (A): Rajasthan is a water-rich state.
Reason (R): It receives heavy rainfall.
a) Both A and R are true
b) A is true, R is false
✅ c) A is false, R is false
d) A is false, R is true
✍️ Short Answer
Q: Why is resource planning essential for India?
A: Because different parts of India have different resources. Some have too much, others have too little. Planning helps in fair and smart use of these resources.
🔗 Connect the Dots
| 🧩 Concept | 🔗 Connects With | 📝 Why They’re Connected |
|---|---|---|
| Resource Planning | Sustainable Development | Smart use of resources ensures long life 🌿 |
| Diversity in resources | Need for sharing and planning | Some places have more, others have less 🤝 |
| Local Planning | Agenda 21 | Local solutions for global problems 🌎 |
| Examples of states | Real-life understanding | Helps students see the need practically |
✨ In Short
Resource Planning = Matching needs with nature.
It helps us use wisely, share fairly, and grow together 💚🌱
📋 RESOURCE PLANNING IN INDIA
🌍 “Planning = Power. But only when used wisely!”
“Having vs. Using
Think about this 👇
You have a big basket of vegetables 🥦🍅🥕 at home. But you don’t know how to cook 🍲.
Will the basket alone feed your family?
No! You need skill, tools, and a plan to turn raw food into a tasty meal. 😋
That’s exactly the case with India’s resources — just having them is not enough.
We need a smart plan to use them properly and fairly across the country.
🇮🇳 What is Resource Planning in India?
Resource planning is not just listing what we have — it’s a full process of
➡️ finding,
➡️ planning, and
➡️ using resources for national development.
🧱 Steps of Resource Planning in India
| 🪜 Step | 📌 What It Means |
|---|---|
| 1. Identification & Inventory | Surveying India’s land to know what resources exist where. (e.g. coal in Jharkhand, water in Kerala) |
| 2. Planning Structure | Making a plan using technology, skilled people, and proper institutions to use the resources. |
| 3. Match with National Goals | Linking resource use with India’s big development goals (like poverty removal, sustainability). |
🇮🇳 India’s Efforts in Resource Planning
- Started after Independence with the First Five-Year Plan (1951–56) 📊
- Made surveys, dams, and development plans
- Built organizations like Planning Commission (now NITI Aayog)
🤔 Why Planning Alone Isn’t Enough
Just having resources ≠ development
Let’s compare 👇
| 📍 Region | 🔍 Resource Status | 💸 Economic Status | 📝 Why? |
|---|---|---|---|
| Jharkhand | Rich in minerals 🪨 | Poor 🏚️ | Lack of infrastructure and industries |
| Punjab | Less minerals 🚫 | Rich 🌾💰 | Developed agriculture, tech, good transport |
| Maharashtra (Mumbai) | Not resource-rich | Very rich 💼🏙️ | Strong industries, finance, global links |
👉 Technology, education, and institutions play a BIG role in development!
🏴☠️ What History Teaches Us: Colonisation
📜 During British rule, India had lots of resources (spices, gold, cotton).
But Britishers took them using better ships, machines, and military.
They used Indian resources for their own development, not ours.
🎯 So, development is not just about having stuff — it’s about how well we use it.
📚 Questions Time!
✅ MCQs
- Which is NOT a part of resource planning?
a) Inventory of resources
b) Fun trips to tourist places ✅
c) Use of technology
d) Linking with national development plans - Which region is resource-rich but economically poor?
a) Punjab
b) Jharkhand ✅
c) Gujarat
d) Maharashtra
❓ Assertion and Reason
Assertion (A): Jharkhand is economically developed because it has lots of minerals.
Reason (R): All mineral-rich states are automatically rich.
a) A is true, R is false
✅ b) A is false, R is false
c) Both A and R are true
d) A is true, R explains A
✍️ Short Answer
Q: Why is resource planning important for India?
A: Because resources are unevenly spread. Some areas are rich in resources but poor in development. So, we need good planning, technology, and skilled people to use them wisely.
🔗 Connect the Dots
| 🔗 Concept | Connects With | 🧠 Why It Matters |
|---|---|---|
| Resource planning | Technology and skills | We can only use resources if we know how 🛠️ |
| Economic development | Historical colonisation | Colonisers used our resources, but we didn’t benefit |
| Uneven resource spread | National development plans | Plans help balance and share resources 🚛 . |
✨ In Short
✅ Resource planning = Finding + Planning + Using wisely
🧠 Just having resources is not enough.
⚙️ We also need technology, skills, and vision.
🇮🇳 India’s journey shows that good planning turns potential into progress.
🌍 CONSERVATION OF RESOURCES
“There’s enough for need, not for greed.”
Mahatma Gandhi
A Chocolate Story 🍫
Imagine your mom brings home one big Dairy Milk bar 🍫 for the whole family.
But before anyone else can have a piece, one person eats most of it!
What happens next?
😡 Fights. 🥺 Sad faces. And no chocolate for the rest.
That’s what happens when we overuse or misuse resources.
We need to share and save them so that everyone can enjoy and benefit.
🧩 What is Resource Conservation?
Resources like water, forests, petrol, coal, land are important for our lives and development.
But if we waste them or use them too much, it creates big problems:
❗Problems due to Overuse:
| ⚠️ Problem Type | 🧨 Example |
|---|---|
| Social | Fights between states over water (like Kaveri river) |
| Economic | Price hike due to fuel shortage |
| Environmental | Pollution, deforestation, land degradation |
So, we must conserve resources — that means using them wisely, not wasting, and making sure future generations also get them.
🧠 What Great Leaders Said
🕊️ Mahatma Gandhi’s Words:
“There is enough for everybody’s need, not for anybody’s greed.”
Gandhiji believed:
- Overuse = Selfishness
- Mass production (by machines) = Greedy
- Production by masses (local people) = Wise & sustainable 🧶👨🌾
🏛️ Global Thinkers & Movements

🏞️ LAND RESOURCES
“What if the ground disappeared?” 🤯
Imagine waking up and there’s no land under your feet.
No houses, no farms, no roads, no cities — just water or air! 😱
That’s how important land is!
Land is not just soil — it’s the stage where life happens 🌍
Let’s explore why land is one of the most valuable natural resources.
🌏 Why Land is So Important
We live on land, work on land, and travel on it.
We grow food 🌾, build homes 🏠, run industries 🏭, and create roads 🛣️ — all on land!
Here’s what land supports:
| 🌿 Supports… | 📌 Examples |
|---|---|
| Human Life | Homes, cities |
| Plants & Animals | Forests, grasslands, wildlife |
| Economic Activities | Farming, factories, mining |
| Transport | Roads, railways, airports |
| Communication | Mobile towers, power lines |
🧠 But remember: Land is limited. We can’t create more of it, so we must use it wisely.
🗺️ India’s Land & Relief Features
India has different types of landforms, called relief features.
📊 Relief Features in India:
| Relief Feature | % of Land | What It Offers |
|---|---|---|
| Plains | 43% | Best for farming 🌾 and cities 🏙️ |
| Mountains | 30% | Rivers, tourism 🏞️, forests 🌲 |
| Plateaus | 27% | Rich in minerals ⛏️, coal, forests |
🏔️ Comparison: Mountains vs. Plains vs. Plateaus
| Feature | Mountains 🏔️ | Plains 🌾 | Plateaus ⛰️ |
|---|---|---|---|
| Height | Very high | Low & flat | Elevated but flat |
| Use | Tourism, forests | Farming, transport | Mining, forests |
| Example | Himalayas | Indo-Gangetic Plains | Deccan Plateau |

a) Both A and R are true, and R is the correct explanation of A ✅
b) A is true, R is false
c) A is false, R is true
d) Both A and R are false
✍️ Short Answer
Q: Why is land called a resource of “finite magnitude”?
A: Because we cannot increase land. It is limited and must be used wisely.
🔗 Connect the Dots
| 🌐 Concept | 🔗 Connected To | 📌 Why? |
|---|---|---|
| Land Resource | Economic Activities | Farming, mining, building all need land |
| Relief Features | Natural Resource Use | Each type offers different resources |
| Finite Land | Careful Planning | Land can’t grow, so we plan use wisely |
✨ In Short
✅ Land is life’s base – we live, grow, and work on it.
🧭 India’s land includes plains, plateaus, and mountains.
⚠️ Land is limited — use it wisely!
🚜 LAND UTILISATION
“How do we divide the land we stand on?”
Have you ever looked out of a train window? You’ll see fields of crops 🌾, houses 🏠, roads 🛣️, maybe some forests 🌳 and empty land too.
But have you ever wondered: How do we use all this land? 🤔
Let’s break it down and understand it in a fun, simple way!
🧭 What is Land Utilisation?
Land Utilisation means:
➡️ How we use land for different purposes like farming, forests, houses, roads, or even letting it rest.
Every piece of land in India falls into one of these 5 main categories 👇
📊 Table: Types of Land Use in India
| Category | What It Includes | Examples |
|---|---|---|
| 1. Forests 🌳 | Land covered by trees and forests | Jim Corbett National Park, Sunderbans |
| 2. Land not available for cultivation 🚫 | (a) Barren & waste land (can’t grow anything) (b) Land used for buildings, roads, etc. | High mountains, cities, factories |

🌱 Bonus Term: Gross Cropped Area
If a farmer grows crops twice on the same land in a year —
👉 That land is counted twice in Gross Cropped Area.
So:
📌 Net Sown Area + Repeatedly sown land = Gross Cropped Area
🧠 Let’s Use Real Life to Understand Better
🎯 Example:
Your school playground can be used in different ways:
- A corner has trees 🌳 (forest land)
- A small area has cement path 🚶 (non-agricultural use)
- A patch where nothing grows (barren land)
- A field used for football and then cricket (net sown + gross cropped)
So even one space can have many uses!
🔁 Comparison: Net Sown vs Gross Cropped Area
| Feature | Net Sown Area | Gross Cropped Area |
|---|---|---|
| Definition | Total land sown once | Total land sown multiple times |
| Counted how many times? | Counted once only | Counted every time crop grown |
| Example | 2 acres used once = 2 acres | 2 acres used twice = 4 acres |

Gross cropped area includes the same land again if more crops are grown in the same year.
🔗 Connect the Dots
| 🌐 Concept | 🔗 Connected To | 📌 Why? |
|---|---|---|
| Land Utilisation | Farming, Housing, Roads | Shows how land is shared among needs |
| Net Sown Area | Gross Cropped Area | One is counted once, the other many times |
| Fallow Land | Soil Fertility 🌱 | Giving land rest improves soil health |
| Forests | Environment & Rainfall ☁️ | Forests help balance nature and climate |
✨ In Short
✅ Land is used in 5 main ways — forests, farming, fallow, uncultivated, and built-up land.
🌱 Sown land used again is added to gross cropped area.
🌍 Wise use of land is important for food, homes, and nature!
🗺️ LAND USE PATTERN IN INDIA
🌍 What Does “Land Use Pattern” Mean?
Just like how we plan different rooms in our house — kitchen for cooking, bedroom for sleeping, playground for fun — India also uses its land for different purposes. This is called land use pattern.
🔍 What Decides How Land is Used?
Land is used based on two types of factors:
| 🌿 Physical Factors | 🧑🤝🧑 Human Factors |
|---|---|
| – Topography (mountains, plains) | – Population density |
| – Climate (rain, heat) | – Culture & traditions |
| – Soil type (black, red, etc.) | – Technology availability |
📏 India’s Land: Big Picture
- Total land area of India: 🧭 3.28 million sq. km
- Land-use data is only available for 93% of it because:
- Northeastern states (except Assam) are not fully surveyed.
- Jammu & Kashmir areas occupied by Pakistan and China are excluded.
🐄 What’s Happening to Pasture Land?
India has a lot of cattle but less land for grazing (called permanent pastures).
👉 This causes overgrazing, less food for animals, and soil erosion.
Story example: Imagine 10 cows sharing 1 tiny patch of grass. What will happen to the grass? 🌱🐄🐄🐄🐄🐄🐄🐄🐄🐄🐄
➡️ It’ll vanish!
🌾 Net Sown Area (NSA): What’s That?
NSA is the land where crops are grown at least once a year.
📈 India’s NSA ≈ 54% of total reporting area
But it changes from state to state:
| State | NSA as % of total area |
|---|---|
| 🟢 Punjab, Haryana | 80% or more |
| 🔴 Arunachal, Mizoram | Less than 10% |
Why the difference?
- Punjab & Haryana: Flat land, rich soil, irrigation
- North-East & Islands: Hilly terrain, forests, rainforests
🌳 What About Forest Land?
- India’s forest area is much less than the ideal 33% suggested in the National Forest Policy (1952).
- Forests are important because:
- They keep air clean, maintain rainfall, and support wildlife
- They support the livelihood of forest-dwelling people
Fun fact: Forests act like Earth’s lungs! 🫁🌳
🏜️ What Is Waste Land?
Waste land = Land not useful for farming or buildings
Includes:
- Rocky areas 🪨
- Deserts 🏜️
- Arid (dry) zones
Also, land used for non-agricultural activities like:
- Roads 🚧
- Railways 🚄
- Factories 🏭
- Towns 🏙️
❗ Problem: Land Degradation
Using land continuously without care or conservation causes:
- Soil erosion
- Desertification
- Loss of fertility
- Floods or droughts
👉 This is called land degradation.
🚨 Land degradation = Danger to environment + threat to farmers + food shortage
💡 Memory Aid (Mnemonic)
🎯 L.A.N.D.S. → 5 categories of how land is used
- L – Livelihood forests 🌳
- A – Agricultural land 🌾
- N – Non-agricultural use 🏠

- Forests are below ideal level; more planting needed.
- Overuse = land degradation = problems for future generations.
🌍 LAND DEGRADATION AND CONSERVATION MEASURES
💬 What Is Land Degradation?
Land degradation means land is losing its fertility, strength, and usefulness due to overuse or misuse by humans or nature.
🧒 Imagine if you kept using the same school notebook without ever caring for it—it would get torn, dirty, and useless. The same happens with land!
👨👩👧 Why Should We Care?
Because:
- 95% of our food, clothes, homes come directly or indirectly from land.
- We inherited land from our ancestors and must protect it for future generations.
🚨 Causes of Land Degradation
Let’s break it down state-wise and cause-wise:
| 📍 State/Region | 🔥 Main Cause |
|---|---|
| Jharkhand, Chhattisgarh, MP, Odisha | ❌ Deforestation due to mining |
| Gujarat, Rajasthan, Maharashtra | 🐄 Overgrazing by cattle |
| Punjab, Haryana, Western UP | 💧 Over-irrigation → waterlogging |
| Cement/Ceramic Industry areas | 🌫️ Dust from grinding rocks |
| Industrial areas (general) | 🧪 Pollution from industrial waste |
📌 Real-Life Examples
- 🏞️ Mining in Jharkhand: Leaves big holes (called scars) and makes soil lifeless.
- 🧂 Punjab & Haryana: Excess water makes the soil salty—bad for crops.
- 🐮 Overgrazing: Like 100 goats eating grass from a single lawn daily!
🛠️ Conservation Measures (How to Save Land)
🌱 1. Afforestation
- Planting trees helps hold the soil together.
🐐 2. Controlled Grazing
- Let animals graze in rotation, not in the same place all the time.
🪨 3. Stabilising Sand Dunes
- Grow thorny bushes to stop desert winds from blowing the soil away.
🗑️ 4. Proper Waste Disposal
- Treat factory waste before dumping it.
⛏️ 5. Control Mining Activities
- Fill up mining pits after use. Avoid leaving open wounds on Earth.
🌾 6. Shelter Belts
- Rows of trees planted to protect crops and prevent soil erosion.
🧠 Think & Answer
Q: Why is over-irrigation a bad thing? Isn’t water always good for crops?
🧑🏫 Answer: Too much water causes waterlogging. It damages roots and makes the soil salty—like when you add too much salt to food, it’s ruined!

🧱 CLASSIFICATION OF SOILS
🌍 What Are Alluvial Soils?
Alluvial soils are fertile soils made by rivers. They are formed by the deposits (sediments) left by rivers like the Indus, Ganga, and Brahmaputra.
🛶 Just like rivers carry mud and sand while flowing, they leave behind this mixture on plains — this becomes alluvial soil.
🗺️ Where Are They Found?
| 🌾 Region | 🏞️ Details |
|---|---|
| Northern Plains | UP, Bihar, Punjab, West Bengal, Assam |
| Rajasthan & Gujarat | Through a narrow river corridor |
| Eastern Coastal Plains | In the deltas of Mahanadi, Godavari, Krishna & Kaveri rivers |
🧪 Composition of Alluvial Soil
Alluvial soil has a mix of:
- Sand
- Silt
- Clay
🎯 Closer to rivers (upstream) = coarse particles
🎯 Farther from rivers (downstream) = finer particles
🧓👶 Types of Alluvial Soils (By Age)
| 🧾 Type | 📍 Found In | 🪨 Features |
|---|---|---|
| Bangar | Older alluvial soil | Has kankar (lime nodules), less fertile |
| Khadar | Newer alluvial soil | Finer particles, more fertile |
🧠 Mnemonic:
Khadar = Kinder = Newer
Bangar = Bigger = Older
🌱 Why Are Alluvial Soils So Important?
They are:
- Highly fertile
- Rich in potash, lime, phosphoric acid
- Good for growing:
- 🥖 Wheat
- 🍚 Paddy
- 🌿 Sugarcane
- 🌾 Pulses
That’s why alluvial soil areas are thickly populated and heavily farmed!
🌵 Alluvial Soil in Dry Areas
In dry regions:
- Alluvial soil becomes alkaline
- But it can still be made productive with proper irrigation and treatment
🧠 Think & Link
Why do you think cities like Varanasi, Patna, and Kolkata are densely populated and fertile?
✅ Because they lie in the Ganga river basin, which is full of alluvial soil.

🌪️ Soil Erosion and Conservation
Let’s protect the Earth, one handful of soil at a time!
🌍 What is Soil Erosion?
Soil erosion means wearing away (denudation) of the fertile topsoil due to wind, water, glaciers or human activities.
🧠 Think of it as the Earth’s skin being peeled off — slowly or suddenly!
🌬️💧 Natural Causes of Soil Erosion
| 🌿 Natural Agent | ⚡ How It Erodes Soil |
|---|---|
| 💧 Running Water | Makes gullies in soft clay soil → forms badlands like in the Chambal basin |
| 💨 Wind | Blows away loose soil in dry regions → wind erosion |
| ❄️ Glaciers | Scrape soil and rock as they move slowly downhill |
🏗️ Human Causes of Soil Erosion
| 🚫 Human Activity | 🔥 Impact |
|---|---|
| Deforestation | No roots to hold soil in place → soil gets washed/blown away |
| Overgrazing | Grass cover removed → soil becomes loose and exposed |
| Mining & Construction | Break natural land cover → causes erosion |
| Wrong Farming Methods | Example: Ploughing up and down slopes creates water channels |
🌪️ Types of Soil Erosion
| Type | What Happens? |
|---|---|
| Gully Erosion | Water makes deep cuts (gullies) in land – e.g., Chambal ravines |
| Sheet Erosion | Water washes away thin layers of soil over large areas |
| Wind Erosion | Loose dry soil blown away by wind (common in deserts) |
🌱 Soil Conservation – Let’s Save Our Soil!
There are many eco-friendly farming and planting methods to stop erosion:
✅ Contour Ploughing
- Ploughing along the natural curves (contours) of the land.
- Slows down water flow, prevents gullies.
✅ Terrace Farming
- Steps are cut on hilly slopes like stairs.
- Slows water and holds soil in place.
- Common in Western & Central Himalayas.
✅ Strip Cropping
- Grass strips are left between crops.
- Breaks wind and stops water flow.
✅ Shelter Belts
- Lines of trees planted to stop wind.
- Used to stabilize sand dunes in western Rajasthan.
