Resources and Development · Class 10 Geography: quick revision, 70 bites

What a Resource Is

Three conditions, all required.

Takeaway. Nothing is a resource on its own.

Testing the Three Conditions

Where each condition fails.

Takeaway. The same substance can be a resource in one place and not in another.

Not Free Gifts of Nature

The chapter asks, then answers flatly.

Are resources **free gifts of nature**, as many assume? **They are not.**

Takeaway. People transform material in the environment into resources and use them.

Nature, Technology and Institutions

A triangle with people at the centre.

Takeaway. Transforming the environment involves all three together.

How Resources Are Classified

Four bases, four sets of categories.

Takeaway. A question naming one basis wants the categories under that one only.

Do Not Run the Bases Together

The commonest way to lose a mark here.

Takeaway. Attach every pair of categories to its own basis.

The Natural Branch

Follow it from the top.

Takeaway. Two levels below renewable, one below non-renewable.

Recyclable Is Still Non-Renewable

A favourite of examiners.

**Recyclable** resources such as **metals** sit under **non-renewable** in the tree.

Takeaway. Recycling extends use; it does not replace what has been taken.

Human Resources in the Tree

The branch students forget.

Takeaway. Human beings are a branch of the tree, not only its users.

Technology Changes the Answer

When a non-resource becomes a resource.

A deposit no machinery could reach was **not** a resource. Build the machinery and, if the cost is bearable and people are willing to use it, the same deposit becomes one.

Takeaway. Nothing in the environment changed — what changed was us.

Responsibility Follows the Definition

Why this definition matters later.

If resources were lying about waiting to be picked up, there would be nothing to plan and nobody to hold responsible.

Takeaway. The definition is what makes resource planning a duty rather than an option.

Continuous or Flow, and Biological

Two words that separate the branches.

Under renewable, **continuous or flow** covers things that keep arriving — **wind** and **water**.

Takeaway. Both are renewable, but for different reasons.

Biotic and Abiotic

Origin, in one line each.

This is the first of the four bases, and it is separate from the renewable and non-renewable split.

Takeaway. Origin asks what a thing came from; exhaustibility asks whether it runs out.

Ownership

Four owners, widening outward.

On the basis of ownership, resources are **individual**, **community**, **national** and **international**.

Takeaway. Four categories, in that order.

Why Resources Were Used Indiscriminately

A mistaken belief, and what followed.

For a long time resources were taken to be **nature handing things over for nothing**, and people drew on them **without any restraint at all**.

Takeaway. The error in the first topic has consequences in this one.

The Three Problems

Quantity, fairness, environment.

Takeaway. Naming all three, and seeing that they differ, is what a full answer does.

Equitable Distribution

What follows from the three problems.

Sharing resources **fairly** is no longer optional: it is what a **lasting standard of living and peace between nations** now depend on.

Takeaway. Resource planning is essential for the sustainable existence of all forms of life.

Sustainable Development

Two halves, both required.

Takeaway. No damage now, and no cost passed to those who come after.

The Rio Earth Summit

June 1992, Brazil.

More than **100 heads of states** met at **Rio de Janeiro**, **Brazil**, in **June 1992** for the **first International Earth Summit**, convened to address urgent problems of **environmental protection** and **socio-economic development**.

Takeaway. One summit, three outcomes worth naming separately.

Agenda 21

Signed at UNCED.

Its targets are **damage to the environment, poverty and disease**, and its method is **nations working together** where **interests coincide, needs are mutual and responsibility is shared**.

Takeaway. Not about climate alone — poverty and disease are named in it.

Local Agenda 21

The objective students miss.

Takeaway. Worth a mark on its own in a question about Agenda 21.

India's Diversity of Resources

Why planning matters here especially.

Planning is the widely accepted strategy for the **judicious use of resources**, and India has **enormous diversity in the availability of resources**.

Takeaway. Uneven distribution is exactly why planning is needed.

Rich in One Thing, Short of Another

Four examples, learn them as a set.

Planning therefore has to be pitched at **every level at once — national, state, regional and local** — or the balance is lost.

Takeaway. Each example shows abundance and shortage side by side.

Resource Planning in India

Three stages, in order.

India has pursued these goals right from the **First Five Year Plan** launched after Independence.

Takeaway. Inventory, structure, match.

Necessary, But Not Sufficient

The most important idea in the section.

Availability of resources is a **necessary condition** for development, but **mere availability** without corresponding changes in **technology and institutions may hinder development**.

Takeaway. Having resources does not make a region rich; lacking them does not make it poor.

Resources and Technology

What colonisation proves.

**Rich resources in colonies were the main attractions for foreign invaders**, and it was the **higher level of technological development of the colonising countries** that let them exploit those resources and establish supremacy.

Takeaway. India experienced all this in different phases of colonisation.

Gandhiji on Greed

One sentence for conservation.

He blamed **greedy and selfish individuals** and the **exploitative nature of modern technology**, and was **against mass production**, wanting **production by the masses** instead.

Takeaway. Note the contrast: mass production against production by the masses.

The Landmarks of Conservation

Four dates, kept apart.

Takeaway. The commonest date error in this chapter.

An Asset of Finite Magnitude

Why land is the constraint.

Everything rests on land — **the plants that grow wild, the animals, people themselves, the economy, and the roads, railways and communication lines**.

Takeaway. Every gain in one land use category is a loss in another.

Relief Features of India

Three shares that add to 100.

Takeaway. India also has islands among its relief features.

Categories of Land Utilisation

The list the data follows.

Takeaway. Five headings, three of them with sub-categories.

Fallow and Waste, by the Clock

Separated purely by time.

Takeaway. One year or less, one to five, more than five.

Net Sown Area and Gross Cropped Area

The pair most often confused.

Takeaway. One measures ground; the other measures sowings.

What Determines Land Use

Three of each.

Takeaway. A question about what determines land use wants both columns.

The Reporting Area

Why 93 and not 100.

India's total geographical area is **3.28 million sq km**, but land use data is available for only **93 per cent** of it.

Takeaway. This is why figures are given as a share of the reporting area.

Net Sown Area Has Barely Moved

Sixty years, almost no change.

Nearly half the reporting area in both years, even as forest and non-agricultural uses grew around it.

Takeaway. The cropped share of India has been close to steady for six decades.

Land Taken for Other Uses

The category that nearly doubled.

Land under **non-agricultural uses** rose from **4.95** to **9.06 per cent** between 1960-61 and 2019-20.

Takeaway. The clearest movement in the whole table.

Permanent Pasture Has Decreased

Less grass, the same cattle.

Land under permanent pasture fell from **4.71** to **3.42 per cent**.

Takeaway. Overgrazing is the answer the next topic gives.

The Forest Shortfall

A target set in 1952.

Forest cover sits **well short of the 33 per cent** the **National Forest Policy (1952)** set as the target — the share it judged **necessary to keep the ecological balance**.

Takeaway. Quote the policy and the year with the target.

45 Per Cent or 54 Per Cent?

Two right answers, so say which.

Most **other than current fallow** lands are of **poor quality** or **costly to cultivate**, so they are cultivated **once or twice in about two to three years**.

Takeaway. Both figures are defensible — name the basis you are using.

Net Sown Area by State

The average hides the range.

Takeaway. Quote the range alongside the average.

What Continuous Use Leads To

The bridge to the next topic.

This has **serious repercussions on society and the environment** — which is where the next topic begins.

Takeaway. The land use table ends by pointing at degradation.

Ninety-Five Per Cent

Why land damage reaches everything.

We share our land with **past generations** and will share it with **future generations** too.

Takeaway. Damage to land is not one problem among many.

Direct and Indirect Damage

One sentence, two claims.

Takeaway. Both halves of that sentence are examinable.

What Degrades Land

Four activities.

These have contributed **significantly** to land degradation.

Takeaway. The chapter then tells you where each one dominates.

Mining and What It Leaves

A chain, not a single cause.

Once the digging is finished **the mine is simply walked away from**, and what stays behind are **deep scars** in the ground and **heaps of over-burden**.

Takeaway. Mining causes deforestation, and the deforestation causes the degradation.

Overgrazing

Where the cattle outnumber the grass.

Across **Gujarat, Rajasthan, Madhya Pradesh and Maharashtra**, the chief culprit behind degraded land is **too much grazing**.

Takeaway. Four states, and the link to the previous topic.

Over-Irrigation

The one that surprises students.

In **Punjab, Haryana and western Uttar Pradesh**, **over irrigation** causes land degradation through **water logging**, leading to an **increase in salinity and alkalinity in the soil**.

Takeaway. Too much of a good input damages land as surely as too little.

Degradation by Region

Match the cause to the region.

Takeaway. Learn these as three groups, not as one long list of states.

Mineral Processing Dust

The damage happens after it lands.

Grinding **limestone for the cement industry** and **calcite and soapstone for the ceramic industry** generates **huge quantities of dust in the atmosphere**.

Takeaway. Once a dust layer forms, rainwater runs off instead of soaking in.

Industrial Effluents

Land and water together.

Over the last few years, **waste discharged by industry** has turned into one of the **biggest polluters of land and water** across large parts of India.

Takeaway. Note that this source damages both land and water.

Afforestation and Grazing Management

The general pair.

**Afforestation** and **proper management of grazing** can help — but the chapter says only **to some extent**.

Takeaway. Note the qualification: to some extent.

In Arid Areas

Measures against wind and sand.

Takeaway. Three measures, all aimed at moving air and moving sand.

In Industrial and Suburban Areas

Measures against waste and excavation.

Takeaway. Note the words 'after treatment' — disposal alone is not the measure.

Which Measures Go Where

Two sets, kept apart.

Takeaway. A question naming an area wants the set belonging to that area.

Match the Remedy to the Cause

Why there is no single cure.

The dominant cause of degradation differs by region — **mining** in the east, **overgrazing** in the west, **over-irrigation** in the north-west.

Takeaway. The two tables of this topic belong together.

Soil Is a Living System

Millions of years for a few centimetres.

Soil is the **most important natural resource**, the **medium plants grow in**, and it is home to many kinds of living things.

Takeaway. Slow to make, quick to lose — which is why conservation closes the chapter.

How Soil Forms

Five factors, then the forces.

Forces of nature also contribute: **change in temperature**, the **actions of running water, wind and glaciers**, and the **activities of decomposers** — along with **chemical and organic changes**.

Takeaway. Soil consists of organic material, called humus, and inorganic materials.

How Soils Are Classified

Colour is only one test.

Indian soils are classified on the basis of the **factors responsible for formation, colour, thickness, texture, age, and chemical and physical properties**.

Takeaway. Six types follow from these tests.

Where Alluvial Soil Is Found

The most widespread soil.

Takeaway. Three river systems in the north, four rivers in the east.

Bangar and Khadar

The pair most often swapped.

Takeaway. Alluvial soil is classified by age into these two.

The Fertility of Alluvial Soil

Why the plains are crowded.

These soils contain adequate **potash, phosphoric acid and lime**, ideal for **sugarcane, paddy, wheat and other cereal and pulse crops**.

Takeaway. Drier-area alluvial soils are more alkaline and need treatment and irrigation.

Black Soil

Regur, and the crop that named it.

Also known as **regur**, it is ideal for **cotton** and so called **black cotton soil**. It is typical of the **Deccan trap (Basalt) region**, made up of **lava flows**.

Takeaway. Climate together with parent rock material formed it.

What Black Soil Holds and Lacks

Rich — but not in everything.

Extremely fine and clayey, **well known for holding moisture**, it develops **deep cracks in hot weather** which aid **aeration** — and is **sticky when wet**, so it must be tilled **immediately after the first shower** or in the **pre-monsoon period**.

Takeaway. The soil that holds moisture best is the one that cannot be worked once wet.

Red and Yellow Soils

One soil, two colours.

Red soil forms over **crystalline igneous rocks** where **rain is light**, in the **eastern and southern Deccan plateau**, and is also found in parts of **Odisha, Chhattisgarh, the southern middle Ganga plain** and the **Western Ghats piedmont**.

Takeaway. Red and yellow are one soil in two states, not two soils.

Laterite Soil

Latin for brick.

Takeaway. Leached, acidic, nutrient poor — the opposite of alluvial.

What Laterite Grows, and When

Tea grows on it — but not because it is fertile.

**Once the right conservation measures are in place** — especially in the hill country of **Karnataka, Kerala and Tamil Nadu** — laterite grows **tea and coffee** very well.

Takeaway. Note the condition — conservation first, crops after.

Arid and Forest Soils

Two soils of difficult country.

Takeaway. Both become useful only in particular places or after work.

Soil Erosion

A balance, and what disturbs it.

Formation and erosion **go on simultaneously** and there is generally a **balance** between them. The balance is disturbed by **deforestation, over-grazing, construction and mining**, while **wind, glacier and water** lead to erosion.

Takeaway. Erosion is not new; what is new is the balance being broken.

Soil Conservation

Four methods, two agents.

Takeaway. Naming a method without naming the agent it defeats is half an answer.
