Understanding sustainability and its importance for global health and wellbeing
Sustainability is central to promoting health and wellbeing around the world. The concept focuses on meeting the needs of current populations without compromising the ability of future generations to achieve similar levels of health and wellbeing. In other words, sustainable practices ensure that improvements to health and wellbeing can be maintained over time.
The key principle of sustainability is intergenerational equity – ensuring that the actions we take today don't negatively impact the ability of future generations to meet their own needs. This concept applies to all aspects of development, from resource use to social structures to economic systems.
The three dimensions of sustainability
Sustainability has three key dimensions that work together to promote health and wellbeing globally:
- Environmental sustainability: Ensuring natural resources are used responsibly and ecosystems are protected for future generations
- Social sustainability: Creating fair and equitable societies that meet the needs of all citizens indefinitely
- Economic sustainability: Maintaining economic growth and development in ways that can be sustained long-term
Understanding each dimension and how it connects to health and wellbeing is essential for explaining sustainability's importance in a global context.
Social sustainability and global health promotion
Social sustainability focuses on creating equitable societies where all citizens' needs can be met over the long term. This dimension includes several important factors:
Safe and decent working conditions
When people worldwide have access to safe and decent working conditions, they avoid forced labour situations. This provides workers with a greater sense of control and purpose in their lives, promoting spiritual health and wellbeing globally. Additionally, safe working environments reduce the risk of work-related injuries, which supports physical health and wellbeing around the world.
Gender equality
Social sustainability also encompasses gender equality. When females in all countries face reduced risk of domestic violence, they may experience lower rates of stress and anxiety. This promotes mental health and wellbeing in a global context.
Social sustainability extends beyond these examples to include access to education, healthcare, adequate housing, and participation in decision-making processes. All of these factors contribute to creating societies where health and wellbeing can be promoted for current and future generations.
Economic sustainability and global health promotion
Economic sustainability involves maintaining economic growth and managing resources in ways that support long-term prosperity. When discussing economic sustainability's importance for health and wellbeing globally, consider factors such as:
- Innovation and economic diversification that creates employment opportunities
- Job security that reduces financial stress and promotes mental health
- Adequate income levels that allow people to afford nutritious food, housing, and healthcare
- Economic systems that don't deplete resources needed by future generations
Economic sustainability is about creating systems that can continue to provide prosperity without exhausting the resources (both natural and human) that make that prosperity possible. This includes ensuring that economic development doesn't create environmental damage or social inequality that undermines future prosperity.
Environmental sustainability and global health promotion
Environmental sustainability ensures that natural resources are preserved and ecosystems protected. Its importance for promoting global health and wellbeing includes:
- Clean air quality that reduces respiratory diseases and promotes physical health
- Safe water supplies that prevent waterborne diseases
- Biodiversity preservation that maintains food sources and medicines
- Climate stability that prevents extreme weather events and their health impacts
Environmental sustainability recognizes that human health is fundamentally dependent on healthy ecosystems. The quality of air we breathe, water we drink, and food we eat all depend on maintaining environmental systems. Additionally, many medicines are derived from plants and animals, making biodiversity crucial for healthcare advancement.
Exam tip: When explaining sustainability dimensions, always connect specific factors to particular dimensions of health and wellbeing (physical, mental, social, emotional, spiritual) and emphasise the global context.
Understanding the Human Development Index
The Human Development Index (HDI) is a key tool for measuring and comparing levels of social and economic development between countries. Rather than relying solely on economic indicators like income, the HDI takes a broader approach to assessing how well people are living.
Components of the HDI
The HDI is calculated using three dimensions and four specific indicators:
| Dimension | Indicator(s) |
|---|---|
| A long and healthy life | Life expectancy at birth |
| Knowledge | Mean years of schooling Expected years of schooling |
| A decent standard of living | Gross National Income (GNI) per capita |
Life expectancy at birth reflects health outcomes and access to healthcare within a country. Mean years of schooling measures the average number of years of education received by adults aged 25 and older, whilst expected years of schooling estimates how many years of education a child entering school can expect to receive. Gross National Income per capita indicates the average income per person in a country.
Interpreting HDI values
The HDI produces a score between 0 and 1, where higher values indicate higher levels of human development.
Interpreting HDI Scores
- An HDI of 0.944 (like Australia's) indicates very high human development
- An HDI of 0.718 (like Indonesia's) indicates high human development
- An HDI of 0.500 would indicate medium human development
When one country has a higher HDI than another, it suggests higher levels of social and economic development. This difference may be due to higher values in any combination of the four indicators: life expectancy at birth, mean years of schooling, expected years of schooling, or Gross National Income per capita.
Advantages of using the HDI
Broader measure than income alone
The HDI is particularly useful because it moves beyond using only economic indicators to measure development. Whilst average income statistics provide valuable information, a high average income doesn't necessarily indicate how well people are living day to day. The HDI incorporates factors relating to other aspects of wellbeing, including health outcomes and educational attainment. This comprehensive approach provides a more complete picture of human development.
By including health and education alongside income, the HDI recognizes that human development is multidimensional. A country might have high average income but poor healthcare access or limited educational opportunities, which the HDI would reflect through lower scores in those dimensions.
Enables meaningful comparisons
The HDI allows for comparisons between countries using a standardised measure. This makes it easier to identify which countries are achieving higher levels of human development and to track progress over time.
Limitations of using the HDI
Based on average data
Although the HDI includes multiple indicators relating to human development, it relies on average data for each country. Therefore, it doesn't provide information about the inequalities experienced within countries. Many population groups face specific challenges in promoting their human development, but the HDI doesn't reflect these disparities. For instance, indigenous populations or minority groups may experience significantly different outcomes than the national average suggests.
The use of averages is a significant limitation because it can mask substantial inequalities. A country might have a high HDI overall while some population groups experience much lower levels of development. This is why the HDI should be used alongside other measures that examine inequality within countries.
Limited range of indicators
Whilst the HDI considers more factors than income alone, it still focuses on just four indicators. Other important aspects of wellbeing and development, such as environmental quality, political freedom, or social connections, aren't captured by the HDI.
The creators of the HDI acknowledge these limitations, which is why complementary measures like the Inequality-adjusted HDI (IHDI) and the Gender Development Index (GDI) have been developed to provide additional perspectives on human development.
Comparing Countries: Australia vs Indonesia
Australia has a higher HDI (0.944) than Indonesia (0.718), indicating higher levels of social and economic development in Australia. This difference may result from Australia having:
- Higher life expectancy at birth
- More years of schooling (both mean and expected)
- Higher Gross National Income per capita compared to Indonesia
However, the HDI doesn't reveal information about inequality within each country or other dimensions of wellbeing. For instance, indigenous Australians may experience significantly lower HDI outcomes than the national average, but this disparity isn't captured in Australia's overall HDI score.
Exam tip: When evaluating the HDI's usefulness, discuss both advantages and limitations. Remember that whilst it's more comprehensive than income measures alone, it still has significant limitations in reflecting the full picture of human development and inequality.
Practice questions
To develop your skills in explaining sustainability and the HDI, consider these practice questions:
- Briefly explain what is meant by economic sustainability and discuss its importance for the promotion of health and wellbeing in a global context.
- Briefly explain what is meant by environmental sustainability and discuss its importance for the promotion of health and wellbeing in a global context.
- Briefly explain the HDI.
- Discuss the degree to which the HDI reflects the level of human development experienced in a country.
- New Zealand has a higher life expectancy than the USA, but the USA has a higher HDI. Explain possible reasons for this.
- Explain why the HDI is often used as an indication of wellbeing instead of average income.
When answering these questions, remember to use specific examples, connect concepts to dimensions of health and wellbeing, and demonstrate your understanding of both the strengths and limitations of the measures discussed.
Key Points to Remember:

Sustainability has three dimensions – environmental, social, and economic – all of which are important for promoting health and wellbeing globally without compromising future generations' ability to do the same.
-
Social sustainability involves creating equitable societies with safe working conditions and gender equality, which promote multiple dimensions of health and wellbeing worldwide.
-
The HDI measures human development using three dimensions and four indicators: life expectancy at birth, mean years of schooling, expected years of schooling, and Gross National Income per capita.
-
The HDI is more comprehensive than income measures alone because it considers health and education outcomes alongside economic factors, providing a broader picture of how well people are living.
-
The HDI has limitations – it's based on average data that doesn't reveal inequalities within countries, and it doesn't capture all aspects of wellbeing and development.
