How this guide works

This focus area studies the diversity and extent of human activity on Earth — the spatial patterns of settlement, infrastructure, agriculture and industry, and patterns related to culture (Indigenous peoples and languages). Use this guide with the seven chapter study pages.

Key geographical concepts (your analytical toolkit)

Place · Space · Environment · Interconnection · Scale · Sustainability · Change. For every pattern, ask: where is it (space), why there (process), at what scale, and how is it changing?

Case & place studies

Real, verified examples that anchor each pattern. Learn one or two per chapter well.

7.2 Settlement
Mega-cities (e.g. Tokyo)

A mega-city is an urban area of over 10 million people (Tokyo ≈37m, plus Delhi, Shanghai…). Uruk (ancient Mesopotamia) is an early example of urban origins.

⚖️ Shows urbanisation & the growth/scale of settlement over time.
7.3 Infrastructure
USA · China (Belt & Road) · Shanghai · Sydney

Contrast ageing infrastructure (parts of the USA) with rapid expansion (China's Belt and Road Initiative & high-speed rail; Shanghai Metro; Sydney Metro).

⚖️ Shows how infrastructure investment shapes economic development & place.
7.4 Agriculture
Extensive commercial (Canadian prairies / Australian outback) · Mediterranean (Tuscany)

Agriculture ranges from subsistence to commercial; the Fertile Crescent is a domestication origin; the Green Revolution transformed yields.

⚖️ Shows spatial patterns of agricultural production & their environmental impact.
7.5 Industrial production
US Rust Belt (decline) · Zhengzhou, China (rise)

Economic restructuring & the new international division of labour have shifted manufacturing from traditional Western belts to emerging economies. Manufacturing is ≈16% of global GDP (World Bank); China is the largest manufacturer by output.

⚖️ Shows change in the spatial pattern of industry over recent decades.
7.6 Indigenous peoples
Aboriginal & Torres Strait Islander peoples · Indigenous Canadians · Māori (Whanganui)

≈476 million Indigenous people worldwide (UN). The Whanganui River gained legal personhood (Te Awa Tupua Act 2017).

⚖️ Shows a cultural spatial pattern & the value of Indigenous knowledge for sustainability.
7.7 Languages
Papua New Guinea (peak diversity) · Australia

About 7,000 languages exist; ~40% are endangered. PNG is the most linguistically diverse country; Australia had ~250 Aboriginal & Torres Strait Islander languages, ~120 still spoken (AIATSIS).

⚖️ Shows a cultural spatial pattern & language loss as change.

Essay practice

Question: Explain how the spatial patterns of ONE type of human activity (settlement, economic activity or culture) are produced, and how they are changing.

Scaffold
Introduction — define the spatial pattern; name the activity + one case/place study.
Body 1 — the pattern: describe where it is (distribution, density, scale) with data.
Body 2 — the processes: explain why there (physical & human factors; interconnection).
Body 3 — change: how the pattern is changing over time + a driver (e.g. globalisation, urbanisation, restructuring), with the case study.
Conclusion — synthesise: pattern → process → change; link to a key concept.

Glossary — key terms

TermMeaning
UrbanisationThe growing share of a population living in urban areas.
Mega-cityAn urban area with over 10 million people.
SettlementA place where people live, from a remote community to a mega-region.
InfrastructureThe basic physical systems & services (transport, water, power, communications) that support activity.
Economic activityThe production, distribution & consumption of goods & services (primary/secondary/tertiary/quaternary).
Green RevolutionMid-20th-C rise in yields via high-yield varieties, irrigation & synthetic inputs.
Economic restructuringA shift in the balance of an economy's activities (e.g. from manufacturing to services).
International division of labourThe global spread of production stages across countries by cost & advantage.
DeindustrialisationDecline of manufacturing in a region (e.g. the US Rust Belt).
Ecological footprintThe biologically productive land & water needed to supply what a population consumes and absorb its waste.
Country (Indigenous concept)An interconnected living whole — land, water, sky, people, law, story — to which people belong.
Traditional ecological knowledge (TEK)Indigenous understanding of land, water & species used in sustainable management.
