Global systems

Welcome to Global Systems!

Hi there! Welcome to one of the most exciting parts of your AQA A Level Geography course. In this chapter, we’re going to look at how the world has become a giant, interconnected web. We call this globalisation.

Think of the world as a massive machine. Instead of every country working alone, they are now "gears" that depend on each other. We’ll explore how money, people, and ideas move around the planet, who holds the power, and why some places get left behind. Don't worry if it sounds like a lot—we’ll break it down piece by piece!

1. What is Globalisation?

At its simplest, globalisation is the process of the world becoming more connected. It’s the reason you can eat a banana from Colombia while wearing a shirt made in Vietnam and watching a video from a creator in South Korea.

The Dimensions of Globalisation (The "Flows")

To understand how the world is connected, geographers look at five main "flows":

• Flows of Capital: This is just a fancy word for money. It moves around the world for investment, trade, or aid.
• Flows of Labour: This is the movement of people. This could be high-skilled doctors moving for better pay or low-skilled workers moving to find jobs in construction.
• Flows of Products: Physical goods being shipped everywhere. The invention of the "standardised shipping container" made this much cheaper and faster.
• Flows of Services: These are things you can't touch, like banking, insurance, or IT support. Many "call centres" for UK companies are actually located in India.
• Flows of Information: Thanks to the internet, data and ideas move instantly across borders.

Did you know? Before shipping containers were invented in the 1950s, loading a ship took days of manual labour. Now, it takes just a few hours using giant cranes!

The Factors Driving Globalisation

Why is this happening so fast now? Several "accelerants" are at work:

1. Technology: The internet and mobile phones mean we can communicate with anyone, anywhere.

2. Transport: Jet aircraft and giant container ships have made the world feel "smaller" (we call this time-space compression).

3. Trade Agreements: Governments have joined groups like the World Trade Organization (WTO) to remove "barriers" like taxes (tariffs) on imported goods.

4. Security: While the world has many conflicts, international "systems" (like customs and border tech) help keep trade moving safely.

Quick Review: Globalisation is driven by flows (Capital, Labour, Products, Services, Information) and pushed forward by technology, transport, and trade deals.

2. Global Systems and Interdependence

Because of these flows, countries are now interdependent. This means they rely on each other. If one country has a problem, it ripples through the whole system.

Types of Interdependence

• Economic: Countries rely on each other for jobs and income. For example, if the US economy crashes, it affects factories in China that sell to the US.
• Political: Countries work together to solve big issues like climate change or war.
• Social: Migration creates strong family and cultural links between different nations.
• Environmental: We all share the same planet. Pollution in one country can cause acid rain in another!

The "Issues" with Interdependence

It’s not all sunshine and rainbows. Interdependence can cause two big problems:

1. Unequal Flows: Money and people don't flow equally. Usually, money flows out of poorer countries and into richer ones. This can lead to brain drain (where all the smartest people leave a poor country to work in a rich one).

2. Unequal Power: Some countries (like the USA, China, and members of the EU) have more "say" in global rules. Smaller, poorer countries often have to just follow what the big players decide.

Analogy Time! Imagine a game of football where one team owns the ball, the grass, and the referee. Even if both teams "play," one team has a huge advantage in making the rules. That’s how global power relations can feel to some countries.

3. International Trade and Access to Markets

Trade is the lifeblood of the global system. However, not everyone has the same "access" to the world's customers.

Trends in Trade

The volume of trade has exploded since the 1980s. While rich countries (HICs) still dominate, "emerging" economies like China, India, and Brazil are now huge players.

Access to Markets

How easy is it for a country to sell its goods? This depends on:

• Wealth: Richer countries can afford to build big ports and fast railways.
• Trade Blocs: Groups like the European Union (EU) make it easy for members to trade with each other, but they often put high taxes on people outside the group.
• SDTs (Special and Differential Treatment): Sometimes, the WTO lets poorer countries have lower taxes to help them grow.

Common Mistake to Avoid: Don't assume globalisation helps everyone equally. While it has lifted millions out of poverty in China, many people in "deindustrialised" areas of the UK or USA have lost their jobs because factories moved to cheaper countries.

4. Transnational Corporations (TNCs)

A TNC is a company that operates in at least two different countries. Examples include Apple, Nike, and Coca-Cola. They are the "architects" of the global system.

How TNCs Organise Themselves

• Headquarters: Usually in a big city in a rich country (like London or New York).
• Research & Development (R&D): Usually stay in rich countries where there are lots of university experts.
• Manufacturing: Often moved to "Low Income Countries" (LICs) where labour costs are lower.

The Impact of TNCs

TNCs bring FDI (Foreign Direct Investment) to a country. This creates jobs and brings in new technology. However, they can also exploit workers with low pay and poor conditions, and they can leave a country overnight if they find a cheaper place to make their products.

Mnemonics for TNC Impacts: Remember "JETS"
J - Jobs (Created by TNCs)
E - Exploitation (Low wages/bad conditions)
T - Technology (New skills brought to the country)
S - Sustainability (Environmental damage caused by factories)

Key Takeaways for This Chapter

1. Globalisation is about connections. It's the movement of money, people, goods, and info.

2. Systems create winners and losers. Wealthy countries and TNCs often control the rules, while poorer nations might struggle with "unequal flows."

3. Interdependence means we are linked. Economic or environmental changes in one part of the world will eventually affect everyone else.

4. TNCs are the powerhouses. They drive trade and investment but can be controversial because of how they treat workers and the environment.

Don't worry if this seems tricky at first! Global systems are complex because the world is complex. Keep thinking about the "connections" and you'll do great!
