G34: Uneven Development and its Consequences
Understanding the physical, economic and historical causes of uneven development, disparities in wealth and health, and consequences including international migration.
🌍 Why is Development Uneven?
Key Concept: Development is uneven at different scales - global (between continents and countries), national (between regions within a country), and local (between neighbourhoods). This unevenness results from a combination of physical, economic, and historical factors.
The global pattern of development shows that most HICs are located in the northern hemisphere, while most LICs are in sub-Saharan Africa and parts of South Asia. The Brandt Line, drawn in the 1980s, illustrates this divide, though it is now less accurate due to the rise of NEEs.
🏔️ Physical Causes of Uneven Development
| Physical Factor | How It Limits Development | Example |
|---|---|---|
| Climate | Extreme heat or cold makes farming difficult; droughts and floods damage crops and infrastructure | Chad experiences persistent droughts, making agriculture unreliable and food insecurity common |
| Landlocked position | No access to sea trade routes; dependent on neighbours for imports/exports; higher transport costs | Rwanda is landlocked, making trade expensive and limiting industrial development |
| Natural hazards | Frequent earthquakes, volcanic eruptions, or tropical storms destroy infrastructure and deter investment | Haiti suffered a devastating earthquake in 2010, setting back development by decades |
| Lack of natural resources | Countries without valuable minerals or energy resources miss out on export income and industrial development | Malawi lacks significant mineral deposits, limiting its export earnings |
| Poor quality land | Infertile soil, steep slopes, or desert limit agricultural productivity | Niger has largely desert terrain with only 12% arable land |
| Disease | Tropical diseases reduce workforce productivity and strain healthcare systems | Malaria kills over 400,000 people annually, mostly in sub-Saharan Africa, reducing economic output |
Important: Physical factors alone do not determine development. Countries like Singapore (hot climate, no natural resources) and Iceland (harsh climate, remote location) are HICs because they have overcome physical disadvantages through good governance, education, and strategic economic decisions.
💷 Economic Causes of Uneven Development
Poor Trade
Many LICs rely on exporting primary products (raw materials, agricultural goods) which have low and volatile prices, while importing expensive manufactured goods. This creates an unfavorable balance of trade.
Trade balance = Value of exports − Value of imports
When imports exceed exports, a country has a trade deficit and may need to borrow, increasing debt.

Debt
Many LICs borrowed heavily in the 1970s and 1980s to fund development projects. High interest rates and falling export prices made repayment difficult. Debt repayments consume a large portion of government revenue, leaving little for healthcare, education, and infrastructure.
Example: The Debt Trap
Mozambique spent over 20% of government revenue on debt servicing in the 1990s - more than it spent on health and education combined. After the Heavily Indebted Poor Countries (HIPC) initiative, Mozambique's debt was reduced, allowing increased spending on social services. Life expectancy rose from 42 years in 1990 to 52 years by 2010.
Transnational Corporations (TNCs)
TNCs can bring investment and jobs to LICs and NEEs, but much of the profit flows back to the HIC where the company is headquartered. TNCs may also exploit cheap labour and weak environmental regulations.
Lack of Investment
LICs often lack the capital to invest in infrastructure, industry, and education. This creates a cycle: poor infrastructure deters investment, which means no improvement in infrastructure.
The Cycle of Poverty
The Vicious Cycle: Low income → Low savings → Low investment → Low productivity → Low income
Breaking this cycle requires external intervention such as aid, foreign investment, or debt relief.

📜 Historical Causes of Uneven Development
Colonialism
European colonial powers (mainly Britain, France, Portugal, Spain, Belgium, and the Netherlands) exploited colonies for raw materials and cheap labour. Infrastructure was built to extract resources, not to develop the local economy. Colonial borders often divided ethnic groups or forced rival groups together, causing conflicts that persist today.
Example: Colonial Legacy in Africa
Belgium's colonisation of Congo (now DRC) was notoriously brutal. King Leopold II exploited rubber and ivory, killing an estimated 10 million Congolese. After independence in 1960, the DRC was left with almost no trained administrators, and conflict has continued for decades. Today the DRC has vast mineral wealth but a GNI per head of only $580.
The Slave Trade
Between the 16th and 19th centuries, an estimated 12.5 million Africans were forcibly taken to the Americas. This depopulated West African societies, disrupted economies, and destroyed social structures. The legacy includes weakened states and continued ethnic tensions.
Conflict
Wars destroy infrastructure, displace populations, and divert spending from development to military. Many post-colonial conflicts were fuelled by Cold War rivalries, with the USA and USSR supplying weapons to opposing sides.
| Conflict | Impact on Development |
|---|---|
| Civil War in Somalia (1991-present) | Collapsed government, no functioning state institutions, famine, piracy |
| Rwandan Genocide (1994) | 800,000 killed; infrastructure destroyed; economy shattered; slow recovery since |
| DRC conflicts (1996-present) | 6 million deaths; mineral wealth funds armed groups; minimal development |
📉 Consequences of Uneven Development
Disparities in Wealth
- The richest 1% of the global population owns more wealth than the other 99% combined
- GNI per head in Burundi ($240) is over 350 times less than in Norway ($87,962)
- Within countries, wealth is often concentrated in urban areas and among elites
- In Brazil, the richest 10% earn 40 times more than the poorest 10%
Disparities in Health
| Health Indicator | LICs (e.g. Sierra Leone) | HICs (e.g. UK) |
|---|---|---|
| Life expectancy | 50 years | 81 years |
| Infant mortality | 76 per 1,000 | 4 per 1,000 |
| Maternal mortality | 1,360 per 100,000 | 9 per 100,000 |
| Access to clean water | 60% | 99%+ |
| Doctors per 1,000 people | 0.02 | 2.9 |
Disparities in Education
- In sub-Saharan Africa, only 67% of children complete primary school, compared to 99% in HICs
- Girls are disproportionately affected - in Afghanistan, only 37% of girls attend secondary school
- Poor education limits job opportunities and perpetuates the poverty cycle
🚶 International Migration
Definition: International migration is the movement of people from one country to another. It is a major consequence of uneven development, as people move from poorer to richer countries seeking better opportunities.
Push Factors (Reasons to Leave)
- Poverty and lack of job opportunities
- War, conflict, and political persecution
- Natural disasters and environmental degradation
- Poor healthcare and education
- Lack of housing and basic services
Pull Factors (Reasons to Move To)
- Better job prospects and higher wages
- Political stability and safety
- Better healthcare and education
- Family members already living there
- More generous welfare systems
Case Study: Migration from Syria to Europe
Since 2011, over 6.8 million Syrians have fled their country due to civil war. Push factors include bombing of civilian areas, persecution by ISIS, economic collapse, and destruction of hospitals and schools. Pull factors include safety in EU countries, established Syrian communities in Germany, and the prospect of employment. By 2019, Germany had accepted over 750,000 Syrian refugees, contributing to labour shortages but also creating integration challenges.
Impacts of Migration
| Host Country (receiving) | Source Country (sending) | |
|---|---|---|
| Positive | Workers fill labour shortages; cultural diversity; migrants of working age support ageing populations | Remittances sent home (global remittances reached $656 billion in 2022); reduced pressure on jobs and services; returnees bring skills |
| Negative | Pressure on housing and services; cultural tensions; wage depression in low-skill sectors; brain drain from source countries | Brain drain of skilled workers (doctors, engineers); family separation; dependency on remittances; ageing population as young leave |
Brain Drain: The emigration of highly trained or qualified people from a country. For example, more Malawian doctors work in Manchester than in the whole of Malawi, severely weakening the country's healthcare system.

✅ Answers
- Being landlocked limits development because the country has no direct access to sea trade routes. This makes imports and exports more expensive, as goods must travel through neighbouring countries, paying transit fees and facing delays. For example, Rwanda's landlocked position means transport costs are around 50% higher than coastal East African countries, discouraging foreign investment and industrial development.
- Colonial powers extracted raw materials from colonies and built infrastructure only to serve export needs, not to develop local economies. They imposed artificial borders that divided ethnic groups and forced rivals together, causing conflicts that continue today. When colonies gained independence, they were left with poorly educated populations, weak institutions, and economies dependent on primary product exports.
- Economic causes include: poor trade terms (LICs export cheap primary goods and import expensive manufactured goods); debt (many LICs spend more on debt repayments than on health and education); lack of investment (poor infrastructure deters foreign investment); and exploitation by TNCs that take profits out of the country.
- Uneven development creates huge disparities in wealth, health, and opportunities between countries. People in LICs experience push factors (poverty, conflict, poor services) while HICs offer pull factors (jobs, safety, better services). This inequality motivates people to migrate internationally to improve their quality of life.
- Positive: Remittances provide a significant source of income (e.g. remittances make up over 30% of GDP in Tajikistan); reduced pressure on limited jobs and services; returning migrants may bring new skills and ideas. Negative: Brain drain removes skilled workers (e.g. many African doctors work in Europe); families are separated; the country becomes dependent on remittances; the population left behind tends to be older.
- A balanced answer would acknowledge that physical factors (climate, landlocked position, natural hazards, lack of resources) can significantly limit development, especially in sub-Saharan Africa. However, economic factors (trade, debt, investment) and historical factors (colonialism, conflict) are often more significant. Countries like Singapore and Japan have overcome physical disadvantages through good governance and strategic economic policies, while some resource-rich countries (e.g. DRC) remain poor due to conflict and corruption. The conclusion should argue that while physical factors matter, they are not deterministic - human factors are equally or more important.
🎯 Exam Tips
- Always use named examples with specific facts and data to support your points
- When evaluating causes, consider physical, economic, AND historical factors - don't focus on just one
- For migration questions, always cover both push and pull factors
- Discuss both positive and negative impacts of migration for both host and source countries
- Use the terms LIC, NEE, and HIC rather than "developed" and "developing"
- For "to what extent" questions, present a balanced argument with a clear conclusion
- Remember: physical factors can be overcome - use counter-examples like Singapore or Iceland
