✅ What is a Resource?

Anything that is technologically accessible, economically feasible, and culturally acceptable is called a resource.

🔹 Examples: Water, forests, minerals, solar energy, etc.

---

🧭 Types of Resources

🔹 Based on Origin

• Biotic: Living things (plants, animals, humans)

• Abiotic: Non-living things (air, water, soil, minerals)

🔹 Based on Exhaustibility

• Renewable: Can be regenerated (sunlight, wind)

• Non-renewable: Limited, can’t be reused (coal, petroleum)

🔹 Based on Ownership

• Individual: Privately owned land or buildings

• Community: Public parks, ponds, playgrounds

• National: Roads, railways, public buildings

• International: Oceans, airspace beyond 200 nautical miles

🔹 Based on Development

• Potential: Available but unused

• Developed: Explored and in use

• Stock: Known, but can’t be used due to lack of technology

• Reserves: Can be used with existing tech

🌱 Need for Resource Planning

India is rich in resources but unevenly distributed. Overuse and mismanagement lead to:

• Depletion of resources

• Environmental damage

• Social conflicts

✅ Resource Planning is needed to conserve and use resources wisely.

🌿 Sustainable Development

"Development that meets the needs of the present without compromising the ability of future generations."

🧠 Gandhiji said: “There is enough for everybody’s need, but not for anybody’s greed.”

🏞️ Land Resources in India

India has 3.28 million sq km of land.

🌍 Land Use Categories:

• Forest: 22.78%

• Net Sown Area: 43.41%

• Barren/Wasteland: 6.29%

• Grazing Land: 3.38%

• Other Uses: 8.61%

⚠️ Land Degradation

❌ Causes:

• Deforestation

• Mining

• Overgrazing

• Over-irrigation (salinity)

✅ Solutions:

• Tree planting (Afforestation)

• Controlled grazing

• Organic farming

🧪 Soil – A Vital Resource

Top fertile layer of land essential for farming.

Soil formation depends on:

• Parent rock

• Climate

• Time

• Relief

• Flora & Fauna

---

🧱 Major Soil Types in India

Soil Type	Characteristics	Found In
Alluvial	Fertile, fine texture	Northern plains, river valleys
Black	Clayey, holds moisture	Maharashtra, Gujarat, Madhya Pradesh
Red	Less fertile, iron-rich	Odisha, Tamil Nadu, Chhattisgarh
Laterite	Hard, rich in iron	Kerala, Karnataka
Arid (Desert)	Sandy, salty	Rajasthan
Forest Soil	Rich in organic matter	Himalayan region

🛑 Soil Erosion and Conservation

⚠️ Causes of Erosion:

• Deforestation

• Overgrazing

• Unscientific farming

🌳 Conservation Techniques:

• Terrace farming: Steps on hills to slow water

• Contour ploughing: Ploughing across slopes

• Shelter belts: Rows of trees to stop wind

• Afforestation: Planting trees
