Cheat Sheet — Resources and Development

🌿 What is a Resource?

Everything in environment that can satisfy human needs provided it is technologically accessible, economically feasible and culturally acceptable

Zimmermann: "Resources are not — they become" — utility defines a resource, not physical existence

Human beings are themselves a vital resource — they transform nature into resources using technology

Nation's development depends not just on resource availability but also on technology, institutions, and political will

🔵 Classification — Origin & Exhaustibility

Basis	Type	Examples
Origin	Biotic	Forests, fish, animals, insects
	Abiotic	Rocks, metals, wind, water
Exhaustibility	Renewable	Solar, wind, tidal, water
	Non-renewable	Coal, petroleum, natural gas

⚠ Non-renewables: Coal takes 300–350 million years to form. Once used — gone forever.

🏛️ Classification — Ownership

Type	Who Owns	Examples
Individual	Private persons	Farmland, plantation, house
Community	All community members	Village pond, grazing land, public parks
National	Nation/state	Rivers, forests, wildlife, minerals, EEZ (12 nautical miles)
International	No single nation	Open ocean, atmosphere, Antarctica, outer space

⚡ Classification — Development Status

Potential Resource: Exists but not yet utilised — e.g. vast solar/wind energy of Rajasthan & Gujarat

Actual Resource: Surveyed, quantified, currently being used — e.g. coal in Jharkhand, Chhattisgarh

Stock: Materials that exist but humans lack technology to access — e.g. hydrogen as fuel (water exists, splitting technology is costly)

Reserve: Subset of actual; technology available but deliberately not used yet — e.g. river water stored for future hydroelectric power

🗂️ Resource Planning in India

Resource planning = judicious use of resources at all levels (national, state, district)

Three Stages:
1. Identification & inventory (surveys, resource maps)
2. Evolving planning structure (institutions, laws)
3. Matching with national development plans

Paradox: Jharkhand, Chhattisgarh, MP — mineral-rich but economically backward. Goa — small, resource-poor but developed. Resource availability ≠ development.

♻️ Sustainable Development

Definition (Brundtland, 1987): "Development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

Rio Earth Summit 1992 → Agenda 21: global blueprint; 179 nations adopted it

Kyoto Protocol 1997: binding GHG reduction targets

Gandhi: "Earth provides enough to satisfy every man's need, but not every man's greed."

India's NAPCC (National Action Plan on Climate Change): 8 national missions including Solar Mission, Energy Efficiency, Green India

🗺️ Land Resources

Land Use Category	Approx %
Net Sown Area	43.4%
Forests	23.4% (target: 33%)
Fallow Lands	10.2%
Non-agricultural Uses	8.0% (growing)
Barren & Wasteland	6.8%
Pastures & Grazing	3.5% (declining)
Culturable Wasteland	4.7%

Total geographical area: 3.28 million sq km · Data for ~93% of area

⚠️ Land Degradation & Conservation

Cause	Region Affected
Deforestation	NE India, Western Ghats, Himalayan foothills
Overgrazing	Rajasthan, Gujarat, Madhya Pradesh
Mining	Jharkhand, MP, Odisha (opencast)
Over-irrigation	Punjab, Haryana (waterlogging & salinisation)
Industrial effluents	Gujarat, Maharashtra

Conservation: Afforestation Contour ploughing Shelter belts Terrace farming Plugging gullies

🟡⬛ Alluvial & Black Soil

Alluvial Soil

Most widespread (~40% of area). Northern Plains + deltas. Deposited by rivers (Indus, Ganga, Brahmaputra). Khadar (new, lighter) vs Bhangar (old, contains kankar). Rich in potash & phosphoric acid. Crops: wheat, rice, sugarcane.

Black Soil (Regur)

Deccan Trap (basalt lava). Maharashtra, Saurashtra, MP, Gujarat. Self-ploughing — swells when wet, cracks when dry. Rich in Ca, Mg, K. Crops: cotton, sugarcane, wheat. Also called Black Cotton Soil.

🔴🧱 Red, Laterite, Arid & Forest Soil

Red Soil

Crystalline igneous rocks. Odisha, Chhattisgarh, MP, Tamil Nadu. Red = iron diffusion. Low moisture & N₂. Crops: wheat, rice, cotton with fertilisers.

Laterite Soil

High temp + heavy rain → leaching. Karnataka, Kerala, TN, MP hills. Rich in Fe & Al, poor in N & K. Hardens = used as bricks. Crops: tea, coffee, cashew.

Arid (Desert) Soil

W. Rajasthan, Kutch. Sandy, low humus. Kankar layer blocks roots. Crops: bajra, pulses. Irrigation can transform it!

Forest Soil

Himalayan slopes, W & E Ghats. Valley soils loamy & humus-rich. Slope soils thin & coarse. Crops: tea, coffee, spices.

💨 Soil Erosion — Types

Sheet Erosion: Thin layer removed uniformly by flowing water — common on gentle slopes after rain

Rill Erosion: Small finger-like channels cut into slope — precursor to gully erosion

Gully Erosion: Deep channels cut into soil by running water — creates bad lands. Classic area: Chambal valley

Wind Erosion: Wind removes top-soil in arid/semi-arid regions — western Rajasthan, sand dunes

Slip Erosion: Large chunks of land slip off on steep slopes — Himalayan & NE hill states

✊ Movements & Global Events

Chipko Movement (1973): Uttarakhand — women hugged trees to prevent felling. Led by Sunderlal Bahuguna

Appiko Movement (1987): Karnataka — similar tree-hugging campaign to protect forests

Narmada Bachao Andolan: Against large dams displacing tribal communities. Led by Medha Patkar

Wangari Maathai (Kenya): Green Belt Movement — planted 30 million trees. Nobel Peace Prize 2004

Rio Earth Summit 1992: Agenda 21 adopted by 179 nations — blueprint for sustainable development

📊 Resource-rich ≠ Developed

State	Resources	Economic Status
Jharkhand	Coal, iron ore, minerals	Among poorest states
Chhattisgarh	Forests, minerals, coal	Low HDI
Goa	Small, resource-poor	Highest per capita income
Kerala	Limited minerals	High HDI, high literacy
Rajasthan	Huge solar/wind potential	Potential not fully harnessed

Key Lesson: Technology + Governance + Education = True Development

🧠 Memory Tricks & Exam Tips

PARS (Resource Status)

Potential → Actual → Reserve → Stock — remember as "PARS"

BICN (Ownership)

Big Individuals Control Nation = Biotic/Individual/Community/National/International

Soil Colour Trick

Red soil = iron (Fe = iron in Latin). Black = basalt. Laterite = brick (Latin: later). Yellow = hydrated iron.

CAFE for Resources

Culturally acceptable, Accessible (tech), Feasible (economic), Environment-based — 3 criteria for a resource

⚠ Common exam mistake: Coal is biotic in origin (formed from plants) but it is non-renewable — don't confuse biotic origin with renewable!
