🌍 Resources and Development
Class 10 Geography • Chapter 1 • Visual Notes
📘 1. What is a Resource?
Anything that has utility, value and can satisfy human needs is called a resource.
⚙️ Utility
It should have some use.
💰 Value
It should have economic or other value.
🔬 Technology
Technology should allow us to use it.
👨👩👧 Human Needs
It should help satisfy human needs.
🗂️ 2. Classification of Resources
On the basis of
Origin
On the basis of
Exhaustibility
On the basis of
Ownership
On the basis of
Development
🌱 A. On the Basis of Origin
🌿 Biotic Resources
Resources obtained from the biosphere and having life.
Examples: Plants, animals and human beings.
🪨 Abiotic Resources
Non-living resources.
Examples: Rocks, minerals and metals.
♻️ B. On the Basis of Exhaustibility
♻️ Renewable
Resources that can be renewed or reproduced naturally.
Examples: Solar energy, wind, forests and water.
⛏️ Non-Renewable
Resources available in limited quantities and taking a very long time to form.
Examples: Coal, petroleum and minerals.
🏠 C. On the Basis of Ownership
👤 Individual
Owned privately by individuals.
Example: House, private land.
👥 Community
Available for use by members of a community.
Example: Public parks and playgrounds.
🇮🇳 National
Resources belonging to the nation.
🌍 International
Resources beyond national boundaries regulated through international institutions.
📈 D. On the Basis of Development
Potential
Resources found in a region but not fully utilised.
Developed
Resources whose quantity and quality have been determined and which are being used.
Stock
Resources that have potential but suitable technology may not be available for their use.
Reserves
Resources that can be used to satisfy future requirements.
⚠️ 3. Development of Resources
Resources are essential for human development, but their careless use can create serious problems.
⚠️ Depletion
Resources may be exhausted through excessive use.
🌡️ Global Warming
Unsustainable resource use can contribute to environmental problems.
🏭 Pollution
Resource exploitation may increase pollution.
⚖️ Inequality
Unequal distribution and control of resources can create inequalities.
🧠 4. Resource Planning
Resource planning means the identification, development and proper utilisation of resources.
Resources
Technology & Skills
Development Plans
Resources are unevenly distributed in India. Some regions are rich in certain resources while others face scarcity. Proper planning helps achieve balanced and sustainable development.
♻️ 5. Sustainable Development
Sustainable development means using resources carefully so that present needs are fulfilled without compromising the ability of future generations to meet their needs.
🌍 6. Land Resources
Land is an important natural resource because it supports agriculture, forests, wildlife, industries, houses, roads and other human activities.
🏔️ Mountains
Important for forests, wildlife and water resources.
🌾 Plains
Important for agriculture and settlements.
⛰️ Plateaus
Rich in minerals and useful for several economic activities.
🏝️ Islands
Support unique ecosystems and human activities.
Major Land-Use Categories
⚠️ 7. Land Degradation
Land degradation means the decline in the quality and productivity of land.
Major Causes
🌱 Control Measures
- Afforestation
- Controlled grazing
- Proper management of wastelands
- Planting shelter belts
- Control of mining activities
- Proper irrigation and water management
🌱 8. Soil as a Resource
Soil is one of the most important renewable natural resources. It supports plant growth and agriculture.
🪨 9. Major Soil Types of India
1️⃣ Alluvial Soil
Mainly found in the Northern Plains and river valleys.
- Very fertile
- Rich in potash and lime
- Suitable for rice and wheat
2️⃣ Black Soil
Mainly found in parts of the Deccan Plateau.
- Clayey
- Holds moisture well
- Suitable for cotton
3️⃣ Red and Yellow Soil
Found mainly in parts of eastern and southern peninsular India.
- Red colour due to iron
- Generally less fertile
- Suitable with proper fertilisation
4️⃣ Laterite Soil
Develops in areas of high temperature and heavy rainfall.
- Strong leaching
- Needs proper manuring
- Tea and coffee can be grown in suitable areas
5️⃣ Arid Soil
Found mainly in dry regions.
- Sandy
- Low humus
- Can become productive with irrigation
6️⃣ Forest and Mountain Soil
Found mainly in mountainous and forested regions.
- Properties vary with altitude
- Influenced by vegetation
- Influenced by climate and slope
💨 10. Soil Erosion
Soil erosion is the removal of the top fertile layer of soil by water, wind and other agents.
Types of Soil Erosion
🌊 Gully Erosion
Running water cuts deep channels or gullies into the soil.
💧 Sheet Erosion
Water flows over a large area and removes the top layer of soil.
🌱 11. Soil Conservation
〰️ Contour Ploughing
Ploughing parallel to the contours of a slope helps reduce water flow and soil erosion.
🏔️ Terrace Farming
Step-like terraces are created on slopes to reduce soil erosion.
🌾 Strip Cropping
Large fields are divided into strips to reduce the force of wind.
🌳 Shelter Belts
Rows of trees are planted to reduce wind erosion.
🌲 Afforestation
Planting trees helps bind soil and reduce erosion.
📊 12. Important Comparisons
| Renewable | Non-Renewable |
|---|---|
| Can be renewed or reproduced. | Available in limited quantities. |
| Can be replenished naturally. | Usually takes a very long time to form. |
| Examples: Solar, wind and water. | Examples: Coal, petroleum and minerals. |
| Gully Erosion | Sheet Erosion |
|---|---|
| Water cuts deep channels in the soil. | Water removes a thin layer over a large area. |
