1. XIV. Selected problems and regions of Asia

Asia: contrasts and hazards · Monsoon Asia, Japan, China, India · Middle East

• Asia: Contrasts, Hazards and Monsoon Lands – Asia is the biggest continent and full of contrasts: the highest mountains, dry plateaus, crowded plains and islands. Moving plates cause earthquakes, volcanoes and tsunamis. The monsoon decides when rain falls and rice grows. Japan, China and India show three different ways of growing rich.

2. XV. Selected problems and regions of Africa

Climate and zones of Africa · Sahel, tourism, food and economy

• Climate Zones of the World – Climate is the average weather of a place over about 30 years. It depends mainly on latitude (how high the Sun climbs), altitude (about 6.5 °C cooler per km up), distance from the sea, winds and ocean currents. Using these, the Köppen system sorts the world into five groups: A tropical, B dry, C temperate, D continental and E polar, plus highland climates on high mountains. Monsoon climates have winds that change direction with the seasons.
• Desertification – Desertification is when good land in dry areas slowly loses its plants and soil and becomes like a desert. It is caused by people (overgrazing, cutting trees, over-farming, poor irrigation) and by nature (drought, rising heat). It does not mean deserts "moving". It brings hunger, dust storms and migration. It can be slowed by planting trees and grass, grazing fewer animals, saving water and fixing sand with checkerboards.

3. XVI. Selected problems and regions of North and South America

Relief, storms and Amazonia · People, cities and economy

• South America: Relief, Climate, Amazonia and Regions – South America is the fourth-largest continent, stretching from about 12° N to 56° S. Its relief has three bands: the young Andes in the west (formed where an ocean plate sinks under the continent), wide lowlands and plains in the centre (Amazon, Orinoco, Pampas), and old highlands in the east. North America has the same pattern. Climate changes with latitude and height: rainforest at the equator, savanna, the Atacama desert, the Pampas grassland and cold, dry Patagonia. The Amazon rainforest is used for cattle, soy, wood, mining and dams, but about a fifth is already cleared. Hazards include earthquakes and volcanoes in the Andes, tornadoes on the plains and tropical cyclones, mostly in the Caribbean and North America. Most people live in big coastal cities.
• Urbanisation: Why Cities Grow and How to Make Them Work – Urbanisation is the rise in the share of a country's or the world's people who live in towns and cities. In 1950 about 30% of the world was urban; since 2007 more than half is, and about 68% is expected by 2050. Cities grow by rural–urban migration (push factors from the countryside, pull factors to the city) and by natural increase. Today the fastest growth is in lower-income and newly emerging countries of Asia and Africa, where megacities of 10 million or more are forming; in many rich countries growth is slow and people also move out to suburbs (suburbanisation and counter-urbanisation). Fast growth brings opportunities (jobs, services) and problems (informal housing, traffic, pollution, waste, flooding, the urban heat island). Sustainable urban development tries to fix these with public transport, green spaces, clean water, recycling, affordable housing and renewable energy.

5. XVIII. Geography of polar regions

Polar regions

• Polar Regions: The Arctic and Antarctica – The polar regions lie around the North and South Poles, roughly inside the Arctic and Antarctic Circles (66.5°). The Arctic is a frozen ocean ringed by land; Antarctica is a continent buried under an ice sheet up to about 4 km thick. They are cold because sunlight arrives at a low angle and spreads out, and because white ice reflects most of it. The 23.5° tilt of Earth's axis gives months of daylight (midnight sun) and months of darkness (polar night). Plants are few; animals such as polar bears (Arctic) and penguins (Antarctica) are adapted with fat, fur and feathers. Indigenous peoples like the Inuit and Sami live in the Arctic; Antarctica has only scientists. Ice cores record past climate. The poles are warming fast; melting sea ice speeds warming (albedo feedback) and melting land ice raises sea level. The Antarctic Treaty keeps Antarctica for peace and science, while Arctic sea routes and resources raise new questions of cooperation.
