This page covers section 8.2.1 of the CIE O Level specification.

  • 8.2.1 - Reasons for differences in levels of development and the development gap, to include social, economic, and environmental factors.

What is the development gap?

What is the development gap?

  • The development gap is the difference in levels of development between the least developed and most developed countries in the world

  • The development gap shows how different these countries are in terms of their wealth, health, and general quality of life

  • The development gap affects how well millions of people live, with high-income countries usually having better living standards and more resources

  • The development gap can cause problems like

    • poverty

    • inequality

    • harm to the environment

    • social unrest

  • The development gap affects global stability and security because problems in poorer countries can impact the wider world

Reasons for the differences in development

Reasons for the differences in development

  • The development gap is a complex problem with many social, economic and environmental reasons

  • These reasons can become less or more important over time

Factors affecting development and human welfare

Environmental factors

  • Landlocked countries have no direct access to ports, making trade more difficult and they often develop more slowly as a result

    • Nine of the twelve most undeveloped countries in the world are landlocked and struggle to trade with other countries

  • Countries with extreme climates develop more slowly, as climate impacts agricultural productivity and infrastructure

  • Natural disasters such as earthquakes and floods occur more frequently in some countries, which diverts money from development to recovery

  • Climate-related diseases and pests, such as malaria, affect the ability of the population to stay healthy enough to work

    • Locust swarms can decimate crops

  • Some countries can meet all their needs from the natural resources they have

  • Many countries have to import some natural resources that are not available within their borders

  • Water, food and energy security are vital to support a country's development

Social factors

  • Demography

    • The birth and death rates, as well as immigration, affect the available workforce

    • Some countries have a large, youthful population but lack education and employment opportunities

  • Technology

    • Can help to increase water, food and energy security

    • Mechanisation of farming increases yields and improved land surveying may reveal more energy sources

  • Conflict and instability can disrupt economic development, hinder investment, and displace populations 

  • Levels of education affect the skills people have. The more educated a population is, the more a country will develop

  • Healthcare affects how well people are, which affects their ability to work

  • Lack of equality can mean that the overall productivity of a country is affected

  • Colonialism – Some countries' colonial past has caused uneven growth, environmental degradation, loss of cultural systems and inequality

    • Colonial powers, such as the UK, France, and Spain, extracted resources from colonies, such as minerals and crops, leaving little wealth behind

    • They also set up systems that benefited themselves, not local people

    • This caused inequality and left many countries dependent on low-value exports after independence

    • Many African and American countries were impacted due to the transatlantic slave trade

Economic factors

  • Corruption can take money away from important projects and make it hard to put good policies into action

  • LICs usually trade primary products for less money to HICs

    • The HIC then produces a final, high-profit product

  • HICs have good road, railway, and electricity infrastructure

    • This helps attract foreign investment because companies can quickly produce and transport goods

    • This boosts a country's development by bringing in money
