Human Environment — Settlements, Transport & Communication

• Settlements — where and why humans live; rural vs urban.
• Transport — how people and goods move; roadways, railways, waterways, airways.
• Communication — how information travels; mass media, internet.

Settlements

A settlement is a place where people build homes and live together.

Types of settlements

Rural settlements

• Located near water bodies (rivers, lakes) and fertile land.
• Compact/Nucleated: houses close together; common in plains and fertile areas (easier defence, shared wells).
• Dispersed: houses spread out over large area; common in hilly/forested areas.
• People mainly depend on agriculture, fishing, forestry.

Urban settlements

• Towns, cities, metropolises.
• People depend on industry, trade, services.
• Develop at crossroads, river ports, or places with natural resources.

Factors that influence settlements

• Water supply: rivers, lakes, springs → essential for drinking and farming.
• Land: flat land preferred for building and farming.
• Climate: mild climate → more comfortable; extreme climates → sparse settlement.
• Defence: hills, islands → easy to defend historically.

Transport

Transport moves people and goods from one place to another.

Roadways

• Most flexible — door-to-door delivery.
• Metalled roads: permanent, all-weather, tarmac/concrete.
• Unmetalled roads: mud tracks; difficult in rain.
• India has one of the world's largest road networks (National Highways, State Highways, district roads).

Railways

• Carries heavy goods and large numbers of passengers over long distances cheaply.
• Essential for landlocked countries.
• India's railway network = 4th largest in the world.
• Limitations: fixed tracks; cannot reach remote areas.

Waterways

• Suez Canal (1869) — connects Mediterranean Sea to Red Sea; shortened Europe–Asia route by ~7,000 km.
• Panama Canal — connects Pacific and Atlantic Oceans.

Airways

• Fastest mode of transport; expensive.
• Ideal for perishable goods, passengers over long distances.
• Airports located near major cities.
• Limitations: weather-dependent, high cost, cannot carry very heavy cargo.

Pipelines

• Carry oil, natural gas, water over long distances.
• Expensive to build but cheap to operate; continuous flow.
• Examples: oil pipelines in the Middle East; gas pipelines across Europe.

Communication

Communication is the process of conveying messages/information.

Personal communication

• Letters (postal), telephone, mobile, email, video calls.
• Internet has revolutionised personal communication — instant global messaging.

Mass communication

Reaches millions of people simultaneously:

Satellites

• Artificial satellites orbit Earth — used for TV broadcasting, weather forecasting, GPS navigation, internet.
• ISRO (India) has launched many communication satellites (INSAT series).

• What is the difference between a compact and dispersed settlement?
• Name four factors that influence where settlements develop.
• What are the advantages of railways over roadways?
• Why is the Suez Canal important for global trade?
• Name three uses of artificial satellites.
