Lesson 6.1: Natural Resources – Water, Forest, Minerals
Natural resources are essential for human survival, economic development, and environmental balance. Understanding their management is key for UPSC exams.
Water Resources:
-
Surface Water: Rivers, lakes, reservoirs – used for irrigation, drinking, and hydropower.
-
Groundwater: Aquifers and wells – overuse leads to depletion.
-
Water Conservation: Rainwater harvesting, watershed management, efficient irrigation techniques.
Forest Resources:
-
Types: Tropical, temperate, and coniferous forests.
-
Importance: Biodiversity, carbon sequestration, climate regulation, timber, and non-timber products.
-
Deforestation Issues: Loss of habitat, soil erosion, climate change.
-
Conservation Methods: Afforestation, protected areas, community forestry.
Mineral Resources:
-
Types: Metallic (iron, copper), Non-metallic (limestone, mica), Energy minerals (coal, uranium).
-
Uses: Industrial growth, energy production, infrastructure development.
-
Sustainable Management: Recycling, efficient mining, substitution with renewable resources.
Key Points for Revision:
-
Types and uses of water, forest, and mineral resources
-
Conservation and sustainable management strategies
-
Role in economy and ecology
Example Question (Prelims Practice):
-
“Which method is commonly used for conserving groundwater?” → Rainwater Harvesting
-
