Key Concepts of Edexcel B Geography: Development Dynamics

Development Theories and Indicators
Two major theories explain global development patterns, though both have their flaws. Rostow's modernisation theory suggests all countries start at the same development level and progress through stages - but it's quite outdated since it ignores the quality of resources, skills, and natural hazards each country faces.
Frank's dependency theory offers a different perspective: developing countries can't progress because they're dependent on developed nations. This creates a cycle where poorer countries remain stuck providing raw materials whilst richer nations benefit from the profits.
Development itself has three key dimensions. Economic development focuses on increasing a country's wealth. Social development measures how well a country serves its people's needs. Political development examines what governments do for citizens - including whether there's corruption or free speech.
Quick Tip: Remember that development is multidimensional - a country might be economically strong but socially weak, or vice versa.
Global inequality stems from various causes including colonialism, international relations, climate, topography, and historical factors. Many of the world's poorest countries are HIPCs (Highly Indebted Poor Countries) that rely heavily on remittances - money sent back by citizens working abroad.
Key indicators help measure development progress. GDP (Gross Domestic Product) shows the total value of goods and services produced annually. GNI (Gross National Income) includes wealth earned abroad. The HDI (Human Development Index) combines social factors like literacy and birth rates, scoring countries from 0-1 . PPP (Purchasing Power Parity) adjusts these figures to show what money can actually buy in different countries.
Development projects come in two main types: top-down development involves large-scale projects like the Three Gorges Dam that don't always benefit local communities, whilst bottom-up development focuses on local-scale education and intermediate technology, often funded by charities like Water Aid.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
