How can social development be improved?

Social development is improved by investing in health, education and gender equality. Top-down strategies led by governments and international aid can fund hospitals, schools, clean water and vaccination programmes. Bottom-up strategies led by NGOs and communities deliver smaller, often more sustainable projects directly to people. The UN Sustainable Development Goals set shared targets for health, education and equality.

What is the ecological footprint?

The ecological footprint measures how much land and sea is needed to provide all the resources a person or country consumes and to absorb the waste they produce. A high footprint, common in richer countries, means using far more than the Earth can sustainably provide. It shows the scale of the demands that rising consumerism places on the environment.

What does sustainability mean and how is it achieved?

Sustainability means meeting the needs of the present without harming the ability of future generations to meet their own needs. It is achieved by reducing resource use and waste (reduce, reuse, recycle), moving to renewable energy and using energy efficiently, living more sustainably (sustainable travel, less meat, local food), and acting at all scales through individuals, governments and international agreements.

Social and Environmental Challenges (Unit 2 Options): a complete overview for WJEC GCSE Geography

Q: What are the Unit 2 Section B options in WJEC GCSE Geography?

Unit 2 has two core themes (Theme 5 and Theme 6) in Section A and two optional themes in Section B, of which students study one. The options are Theme 7, Social Development Issues, and Theme 8, Environmental Challenges. Both are part of the Unit 2 written exam (1 hour 30 minutes, 35 percent) and examined by data response.

Q: What is the difference between economic and social development?

Economic development is about a country's wealth, measured by indicators such as GNI per head. Social development is about the quality of life and wellbeing of people, measured by social indicators such as life expectancy, infant mortality, literacy, gender equality and access to services. The two do not always match, because wealth must be invested in people and shared fairly to raise social development.

What this covers

The Unit 2 Section B options are studied one at a time: Theme 7, Social Development Issues, or Theme 8, Environmental Challenges. Both sit in the Unit 2 written exam (1-hour 30-minute, 35 percent) and are examined by data response. This overview ties together the social-development content (measuring it, responding to it) and the environmental content (consumerism, managing it sustainably).

Economic development is about wealth; social development is about quality of life, measured by health (life expectancy, infant mortality), education (literacy), gender equality and access to services. The two do not always match. Social development varies between and within countries (urban-rural, regions, social groups, gender). Its consequences when poor include ill health, low literacy, continued poverty and a weaker economy. It is improved by top-down (aid, government, health programmes) and bottom-up (NGOs, local schemes) strategies, guided by the UN Sustainable Development Goals.

Theme 8: environmental challenges

Consumerism (buying ever more goods) has grown with population, income, advertising and a throwaway society, raising demand for resources and energy. The ecological footprint shows how much land and resources we use; high footprints are common in richer countries. The impacts are resource depletion, waste, pollution and climate change. These are managed sustainably through the three Rs (reduce, reuse, recycle), renewable energy and energy efficiency, sustainable living, and action by individuals, governments and international agreements.

The Unit 2 Section B options are Theme 7 (Social Development Issues) and Theme 8 (Environmental Challenges); students study one, in the Unit 2 written exam (1 hour 30 minutes, 35 percent, data response). Theme 7 covers the difference between economic and social development, the indicators of social development (health, education, gender equality, access to services), why it varies within and between countries, the consequences of poor social development, and the responses (aid, government and health programmes, NGOs, and the UN Sustainable Development Goals). Theme 8 covers the growth of consumerism and rising demand for resources and energy, the ecological footprint, the environmental impacts (resource depletion, waste, pollution, climate change), and managing them sustainably through the three Rs, renewable energy, energy efficiency, sustainable living, and action by individuals, governments and international agreements. Both themes are examined by data response.
