South 고등학교 2학년 World Citizenship and Geography
Chapters: 4
1. Global citizens, globalisation and regions
Globalisation at different scales · Regional integration and separation · Geospatial technology for citizens
- Globalisation and Global Governance – Globalisation is the growth of flows of goods, capital, information and labour that tie places together. Technology, transport and trade deals drive it. The flows are unequal: rich economies hold more power, poorer ones have weaker market access. TNCs spread production of one product across many places. Agencies like the UN, WTO, IMF and World Bank try to govern these flows, and treaties protect global commons such as Antarctica. Globalisation brings growth and cheaper goods but also inequality, conflict and environmental harm.
- Regional Integration – Regional integration is when neighbouring countries join hands step by step: they trade with fewer taxes, share one market, and sometimes one currency and rules. Examples are the EU, ASEAN, USMCA and the African Continental Free Trade Area. It brings cheaper goods and peace, but countries give up some control.
- Spatial Information Technology: GIS (Class 12 Geography Practical) – A Geographical Information System (GIS) is a computer system that stores, links, analyses and shows data about places. It keeps the world in layers. It needs hardware, software, data, people and methods. Spatial data come in raster (grid of cells) and vector (points, lines, polygons) formats. Data are entered by digitising, scanning, GPS or satellite images and linked to attribute tables. Overlay combines layers to find where conditions meet; buffer draws a zone of fixed distance around a feature.
2. A mosaic world: natural environments and cultures
World climates and life · Major landforms and human life · World religions and landscapes · Food and festivals geographically
- 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.
- Major Landforms and How They Form – Landforms are the natural shapes of the land: mountains, volcanoes, plains, valleys, deltas, beaches and caves. Forces from inside the Earth (plate movement, volcanoes) build them up. Forces from outside (rain, rivers, waves, wind, ice) wear them down and move the pieces. People choose where to live and work according to these landforms.
- Cultural Geography: How Places Shape Culture and Culture Shapes Places – Cultural geography studies how human culture differs from place to place and how it spreads. Culture is a group's shared way of life: language, religion, food, clothing, buildings, art and festivals. People change the land to fit their culture, making a cultural landscape. The natural environment, especially climate and nearness to the sea, influences homes, food and clothing, though people also use technology and choice. Areas with similar traits form culture regions. Cultures start in hearths and spread by diffusion: relocation (people move) or expansion (the idea moves), which can be contagious, hierarchical or stimulus. Diffusion can lead to acculturation, assimilation, syncretism and, today, globalisation.
3. A networked world: population and economy
World population patterns · Food production and consumption · Transnational firms and global economy
- The World Population: Distribution, Density and Growth – People are not spread evenly on Earth. Most live on fertile plains near water; few live in deserts, high mountains or icy lands. Density tells how many people live on each square km. Geographical, economic and social factors explain the pattern. The world grew slowly for thousands of years and then very fast after 1800. Population changes through births, deaths and migration. The demographic transition theory shows how birth and death rates fall as a society moves from rural farming to urban industry. Countries use family planning and health care to control growth.
- Food Security: Feeding Everyone, Every Day – Food security means every person, at all times, can get enough safe and nutritious food for an active, healthy life. It rests on four pillars: availability (food is produced or imported), access (people can afford and reach it), use (good nutrition, clean water, safe cooking) and stability (supply does not collapse in bad years). Food supply is uneven across the world. Demand keeps rising with population, incomes and changing diets, while climate change, water shortage, soil loss, conflict and waste limit supply. Food insecurity causes hunger, malnutrition, high prices, migration and unrest. Supply can be raised by irrigation, better seeds, new technology and cutting waste, but long-term answers must also be sustainable and fair.
- Globalisation and Global Governance – Globalisation is the growth of flows of goods, capital, information and labour that tie places together. Technology, transport and trade deals drive it. The flows are unequal: rich economies hold more power, poorer ones have weaker market access. TNCs spread production of one product across many places. Agencies like the UN, WTO, IMF and World Bank try to govern these flows, and treaties protect global commons such as Antarctica. Globalisation brings growth and cheaper goods but also inequality, conflict and environmental harm.
4. A sustainable world: environment and peace
Energy production and consumption · Global environmental problems · Geopolitical conflicts and peace efforts
- Minerals and Energy Resources – Minerals are natural substances found in rocks. They are metallic (ferrous or non-ferrous), non-metallic, or energy minerals. Energy comes from conventional sources like coal, petroleum, natural gas and electricity, and from non-conventional sources like sun, wind, nuclear, biogas, tides and heat from the Earth. Both minerals and energy must be conserved.
- Climate Change and the Greenhouse Effect – Climate is the average weather of a place over about 30 years. Greenhouse gases like carbon dioxide and methane trap some of the heat the Earth gives off. Humans have added a lot more of these gases by burning fossil fuels and cutting forests, so the Earth is warming. This causes melting ice, rising seas and more extreme weather. We can cut emissions (mitigation) and prepare for changes (adaptation).
- International Relations: How States Deal with Each Other – International relations (IR) studies how states and other actors (international organisations, companies, NGOs) interact. States are sovereign and there is no world government, so each state follows its national interest through foreign policy: diplomacy, trade, aid, alliances and, at worst, force. Conflicts arise from clashing interests over territory, resources, power and identity, and from the security dilemma. Cooperation grows through mutual gain, treaties, international law and organisations. Realism stresses power and security; liberalism stresses cooperation, trade and institutions. Peace is built by negotiation, mediation, peacekeeping and justice.
