Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

The examinable core. “Explain the concept of human development” (January 2026, 10 marks), “Sustainable development” (short or 10-mark note in both February 2025 and January 2026) and “Development theory” (January 2026 short note). The move from economic growth to human and sustainable development is the thread through all three.

1. From growth to development

After the Second World War development was measured by economic growth, chiefly the rise in gross national product per head. By the 1970s it was clear that growth could coexist with poverty, unemployment, inequality and environmental damage. Development came to mean an improvement in the quality of life of all people, not only in output. The three perspectives in the syllabus are stages in that rethinking.

2. Human development

Human development is the process of enlarging people’s choices and capabilities, so that they can lead long, healthy and creative lives. The concept was developed by the Pakistani economist Mahbub ul Haq and the Indian economist Amartya Sen, and adopted by the United Nations Development Programme, which has published the Human Development Report each year since 1990.

Four pillars of human development

  1. Equity — equal access to opportunities for all, irrespective of gender, caste, race or income.
  2. Productivity — investment in people (health, education) so that they can work productively.
  3. Sustainability — opportunities for future generations must not be sacrificed.
  4. Empowerment — people should participate in the decisions that shape their lives.

The Human Development Index

DimensionIndicator
A long and healthy lifeLife expectancy at birth
KnowledgeExpected years of schooling; mean years of schooling
A decent standard of livingGross national income per capita (PPP dollars)

The HDI ranges from 0 to 1; since 2010 it has been calculated as the geometric mean of the three dimension indices. Related UNDP indices include the Gender Inequality Index and the Multidimensional Poverty Index. Kerala is the Indian example usually cited of high human development at modest income, owing to investment in literacy and health.

3. Social development

Social development is the improvement of the well-being of people and of social relationships and institutions: reduction of poverty, inequality and exclusion; access to education, health, housing and social security; and the inclusion of marginal groups. The World Summit for Social Development, held at Copenhagen in 1995, committed States to three core aims: eradication of poverty, full employment and social integration.

4. Sustainable development

The classic definition comes from the World Commission on Environment and Development (the Brundtland Commission) in Our Common Future (1987): sustainable development is “development that meets the needs of the present without compromising the ability of future generations to meet their own needs”.

5. Theories of development and underdevelopment

Modernisation theory

Underdevelopment is an original state; poor countries are “traditional” and will develop by adopting the values, institutions and technology of the West: rationality, achievement, urbanisation, education, democracy. W.W. Rostow (The Stages of Economic Growth: A Non-Communist Manifesto, 1960) set out five stages: the traditional society; the preconditions for take-off; the take-off; the drive to maturity; and the age of high mass consumption. Talcott Parsons’s pattern variables and Daniel Lerner’s study of the Middle East belong to this school.

Criticism: it is ethnocentric, treats tradition as a barrier, ignores the effect of colonialism and of the world economy, and history has not followed its stages.

Dependency theory

Developed by Latin American scholars (Raúl Prebisch, Theotonio dos Santos) and Andre Gunder Frank (“The Development of Underdevelopment”, 1966). Underdevelopment is not an original state but the result of the development of the West. The world is divided into a metropolis (core) and satellites (periphery); surplus flows from the periphery to the centre through colonialism, unequal trade and multinational capital. Dadabhai Naoroji’s “drain of wealth” from India is an early version of the argument. The remedy is self-reliance or delinking.

Criticism: it cannot explain the rise of the East Asian economies, and it neglects internal causes such as corruption and inequality.

World-systems theory

Immanuel Wallerstein (The Modern World-System, from 1974) sees a single capitalist world economy since the sixteenth century, divided into core, semi-periphery and periphery. Countries can move between zones, which explains mobility better than dependency theory.

Other approaches

The Gandhian model of village self-sufficiency and decentralisation; the Nehru-Mahalanobis model of State-led heavy industry; human development and capability theory; and alternative or people-centred development stressing participation and ecology.

Modernisation and dependency are opposites. One says poor countries are poor because they are traditional and need contact with the West; the other says they are poor because of that contact. Set this contrast out in two columns.

How this is examined

Human development: Haq and Sen, four pillars, HDI table, and how it differs from economic growth. Sustainable development: the Brundtland definition verbatim, three pillars, milestones to the SDGs, Indian constitutional provisions. A note on development theory takes modernisation (Rostow’s five stages) and dependency (Frank) with criticism of each.
