Approaches to Development and Sustainability
Global North
Refers to economically and industrially advanced countries, generally located north of less developed nations.
Global South
Refers to countries with lower levels of economic and industrial development, typically found south of more developed nations.
Three Development Theories
1. Modernization Theory
- Suggests countries develop in 5 linear stages (Rostow):
- Traditional → 2. Transitional → 3. Take-off → 4. Drive to maturity → 5. Mass consumption
- Global South can catch up to Global North by replicating its path: free markets, democracy, industrialization.
- Criticism: Ignores colonial legacies, assumes all countries follow same path.
Modernization Theory: South Korea
- In the 1960s, South Korea was a poor, rural country.
- Followed a Western-style development path:
- Industrialised, expanded education, adopted capitalism, and moved towards democracy.
- Today, it is a high-income, democratic nation with advanced technology and exports.
- What it shows:
- South Korea’s development reflects Rostow’s five stages, supporting Modernisation Theory’s idea that countries can "catch up" by following the same model as the Global North.
2. Dependency Theory (Neo-Marxism)
- Global South remains poor due to historical colonial exploitation and ongoing dependence on the Global North.
- Structures of trade, aid, and investment favour the North.
- Key issues:
- Commodity concentration: Reliance on a few exports (e.g., copper from Zambia).
- Protectionism by the North: Rich countries promote free trade but impose tariffs on goods from the global south.
- Aid often supports elites and imposes conditions
Dependency Theory: Zambia and Copper Exports
- Zambia is heavily dependent on copper, which makes up over 70% of its export revenue.
- Most of its copper is sold to and processed in richer nations (e.g., China, Switzerland).
- Despite this valuable export, Zambia remains poor due to:
- Unfair trade terms (prices set by buyers),
- Foreign ownership of mines (profits leave the country),
- Commodity price fluctuations hurting the economy.
3. Neoliberalism
- Promotes global free trade, comparative advantage, and reduced government intervention.
- Belief: Market liberalization helps all countries develop.
- Criticism: Overlooks global inequalities and internal capacity limits in poorer states.
Neoliberalism: United States under Reagan (1981–1989)
- Key neoliberal policies:
- Tax cuts for the wealthy and corporations (“trickle-down economics”).
- Deregulation of industries (e.g. banking, airlines, and telecommunications).
- Privatisation of public services and reductions in welfare spending.
- Promotion of free trade and open markets globally.
- Impact:
- Stimulated economic growth and innovation.
- Encouraged global investment and financial expansion.
- But also:
- Widened income inequality.
- Weakened labor unions.
- Reduced social safety nets.
Capability Approach (Amartya Sen & Martha Nussbaum)
- Focuses on what people are able to do and be, not just economic growth.
- Key ideas:
- Functionings: states of being (e.g. being healthy, educated).
- Capabilities: real freedoms/opportunities to achieve functionings.
- Sen’s example: A starving person vs. a fasting person – both aren't eating, but only one has the choice.
- Nussbaum’s key capabilities include:
- Life, health, imagination, emotional attachments, recreation, political freedom, etc.
Capability Approach: Girls’ Education in Afghanistan
- Girls may have schools nearby, but social or political restrictions (e.g. Taliban rule) prevent them from attending.
- Even if education is available, their lack of choice means they lack capability.
- Key idea: Development is about having the freedom to choose, not just access to resources.
- What are the five stages of Rostow’s Modernization Theory?
- How does Dependency Theory explain underdevelopment in the Global South?
- In what ways do Neoliberalism and Dependency Theory disagree on the causes of underdevelopment?
