Development & human welfare

Development is the progress of a country in terms of economic growth, the use of technology, and the quality of life of its people.

Human welfare is the overall wellbeing of a population — health, education, safety, and access to services such as clean water and sanitation.

• As a country develops it usually becomes wealthier, but also healthier, better educated and more connected.
• Development has an economic side (income, industry) and a social side (welfare, rights, opportunity).

Watch out: development is not only about wealth. A country can be rich in money but still have poor human welfare (e.g. low life expectancy or wide inequality). That is why geographers use several measures, not just income.

What is development?

Economic vs social indicators

We measure development with indicators. Some are economic (about money), some are social (about welfare):

Key term: per capita means "per person" — a total (e.g. GNI) divided by the population, so big and small countries can be compared fairly.

GNI & GDP per capita

GDP (Gross Domestic Product) is the value of all goods and services produced inside a country in a year. GNI (Gross National Income) adds income earned abroad too.

• The World Bank uses GNI per capita to classify countries as high, middle or low income.
• PPP (purchasing power parity) adjusts for how much money actually buys in each country.

Misconception alert: GNI per capita is an average, so it hides inequality. A country can have a high GNI per capita while a large share of people stay poor, because a small wealthy group pulls the average up.

Which kind of indicator?

Your turn — GNI per capita

The Human Development Index (HDI)

A single indicator can mislead, so the UN's HDI is a composite — it combines three things into one score from 0 to 1:

Misconception alert: HDI is composite, so it gives a fuller picture than income alone — but it is still an average and does not directly show inequality or human rights.

Your turn — reading HDI

Indicator → what it measures

The global development gap

The development gap is the difference in wealth and human welfare between the most and least developed countries. It creates deep global inequalities.

Development is uneven both between countries (global scale) and within a country (e.g. rich cities vs poor rural areas).

HIC, MIC & LIC

The World Bank groups countries by GNI per capita:

• HIC — High Income Country (e.g. UK, Japan). High GNI, high welfare.
• MIC — Middle Income Country, including fast-growing NEEs (e.g. India, Brazil).
• LIC — Low Income Country (e.g. Malawi). Low GNI, often lower welfare.

Link to the DTM: as countries develop they move through the Demographic Transition Model. LICs sit in early stages (high birth & death rates), while HICs reach later stages (low birth & death rates, ageing population).

Classifying a country

Why development is uneven

The development gap has several causes, which examiners group into four types:

• Physical — climate, natural hazards (droughts, floods), being landlocked, poor soils, tropical disease.
• Economic — reliance on primary products whose prices fall, poverty trap, lack of investment.
• Historical / colonial — colonialism drained resources and shaped unfair trade; the effects still linger.
• Political — war and conflict, corruption, or weak/unstable government that fails to invest.

Trade trap: many LICs export cheap raw materials but import expensive manufactured goods — so wealth flows out, widening the gap.

Naming a cause

Consequences of uneven development

A wide development gap has serious effects:

• Disparities in wealth — extreme poverty in LICs alongside rising wealth in HICs.
• Disparities in health — lower life expectancy, higher infant mortality, poorer healthcare.
• International migration — people move from LICs to HICs seeking work and safety.
• Social unrest — inequality can fuel tension and instability.

Strategies to reduce the gap

Many strategies aim to raise development and human welfare in poorer countries:

• Aid — money, goods or expertise given by governments (bilateral/multilateral) or NGOs (e.g. Oxfam).
• Trade & fair trade — freer trade, and Fairtrade paying farmers a fair, guaranteed price.
• Investment — by governments, the World Bank or TNCs building factories and infrastructure.
• Intermediate technology — small-scale, affordable, appropriate tech (e.g. hand pumps, solar lamps).
• Debt relief — cancelling debt so money can go to schools, water and healthcare instead.

Top-down vs bottom-up

Strategies work in two very different ways:

Compare: top-down schemes can be large and fast but may not suit local needs; bottom-up schemes suit local needs and give people control, but are usually small in scale.

Top-down or bottom-up?

TNCs & international agencies

Transnational corporations (TNCs) operate in many countries. By investing in LICs/MICs they can:

• Bring jobs, wages, skills, technology and infrastructure (roads, ports).
• But profits may leave the country, wages can be low, and working conditions poor.

International agencies also shape development:

• World Bank & IMF — lend money and fund large projects (often top-down).
• United Nations (UN) — sets goals and coordinates aid and health programmes.
• NGOs (e.g. Oxfam, Practical Action) — run smaller, often bottom-up projects.

Role of a TNC

Case study: The Green Belt Movement, Kenya

A real, located bottom-up development scheme you can use in the exam:

• Where: Kenya, East Africa (an LIC/MIC). Started 1977 by Wangari Maathai.
• What: a community project where local people — mostly rural women — are paid to grow and plant tree seedlings.
• Scale: over 50 million trees planted and tens of thousands of women trained and given an income.

Exam use: quote the place (Kenya), the scheme (Green Belt Movement), a fact (50+ million trees) and explain it as a bottom-up strategy that improves both the environment and human welfare.
