Humans are captivated by growth. From the early steps of a young child to the sprawling branches of a towering oak tree, growth signals progress and potential. In our personal lives, we celebrate each birthday, and in sports, we cheer as athletes break records, pushing the limits of human performance. We admire cities that expand and technologies that advance because growth often represents improvement and prosperity.

However, this attraction to endless growth overlooks a critical fact: in the natural world, endless growth is neither possible nor desirable. Nature works in cycles of growth, decay, and renewal. But somehow we expect our economies to defy nature, to grow in size forever. In this section, we explore the Doughnut Economics model, which challenges us to rethink the goal of economic growth, striving instead for meeting human needs within Earth's limits.

What is the Doughnut Economics model?


In 2017, economist Kate Raworth developed the Doughnut Economics model to explore how human needs relate to Earth’s ecological limits. Raworth merged the social Sustainable Development Goals (SDGs) with the planetary boundaries model (Section 1.2.7), creating a model that looks like a doughnut (Figure 1).

Social foundation

The inner ring of the Doughnut model (Figure 3), represents the social foundation for meeting human needs: sufficient food; clean water and decent sanitation; access to energy, education, health care and networks of information, mobility and social support; decent housing, sufficient income and decent work. Equity, political voice and peace and justice help ensure that the needs of all are met in our social and political systems. You can see that the Doughnut’s social foundation is based on the social priorities set out in the Sustainable Development Goals (SDGs) shown in Figure 4.

Ecological ceiling

Figure 5 shows the model's outer ring, the ecological ceiling representing Earth’s nine life-supporting systems and their ecological limits, drawn from the planetary boundaries model (Section 1.2.7). 


In the Doughnut model, some of these boundaries are described in simpler terms. For instance, "biosphere integrity" becomes “biodiversity loss” and "novel entities" become "chemical pollution”. These boundaries represent the maximum safe level of disturbance to Earth’s systems from human activities.

Meeting human needs within planetary boundaries

We need to design our economies so that we do not leave anyone in the hole of the Doughnut without their needs being met, nor exceed the capacity of Earth’s systems to support us. This sweet spot is the green Doughnut, the “safe and just space for humanity” where humans can thrive in balance with nature, as Raworth describes in the short video below.

Global data show that humanity is currently far from reaching the Doughnut’s goals. Billions of people cannot yet meet their basic needs, and humanity has collectively already overshot many of Earth’s planetary boundaries. Figure 6 shows this shortfall on the social foundation and overshoot on planetary boundaries in red.

Our global economy is failing to meet the goals of human and ecological wellbeing, but also no individual country has fully achieved these goals, but there are significant differences between countries.

Figure 7 compares Australia and Yemen. Australia has made good progress in meeting social needs, but greatly exceeds environmental limits. Yemen, in contrast, stays within environmental limits, but falls short in fulfilling its people's essential needs. You can compare over 150 countries’ Doughnuts on the University of Leeds A Good Life For All Within Planetary Boundaries website (see activity at the end of this section).

It’s no surprise to see an overall positive relationship between the average incomes in a country and human needs being met. Higher incomes in Australia enable more people to buy what they need than in Yemen, and higher tax revenues for the Australian government enable it to provide better public services and  social support than in Yemen. The ability to use higher national income to purchase more goods and services to meet human needs is one reason why so many governments continue to prioritise economic growth.


However, it is also not surprising to see that high income countries are greatly exceeding planetary boundaries. Economies use energy and matter to meet human needs and wants, so the economies of high-income countries tend to place excessive pressure on nature.

But there is more to the story. Some countries achieve very high levels of human wellbeing, with a much lower ecological impact. They use natural resources much more efficiently to meet human needs. Costa Rica is an example (Figure 8). The middle-income country has a higher life expectancy and life satisfaction than many high-income countries. Costa Rica has focused on public health, with universal health care, water, sanitation and energy infrastructure. There is free education and a guaranteed state pension, and strong social connection. Since 1987 Costa Rica has been protecting and restoring the health of its rainforest. Can you find Costa Rica in Figure 8?

Costa Rica still has room for improvement, but it shows that the high income countries to the right in Figure 8 can achieve high standards of living with much lower ecological impact. They can do this by redesigning their economies to focus on human wellbeing and meeting real human needs, rather than simply expanding economic output aimlessly. Ensuring that everyone has access to essential goods and services, along with distributing incomes and wealth more evenly, can significantly improve a nation's ability to meet the needs of all its inhabitants with far lower ecological impact.


Countries at the lower left side of Figure 8 will need to use more energy and material resources as they seek to meet the needs of all their people. It is important for higher income countries to reduce their excessive use of energy and materials in order to make room for other countries that need to increase their energy and resource use. With better economic design of provisioning systems (Section 1.3.5) every country can achieve the ‘good life’ within planetary boundaries.

Activity 1.3.4

Option 1 - Connecting the social foundation and ecological ceiling

20 minutes (or more if you make a Doughnut spinner)

You can explore possible tensions between the social foundation and the ecological ceiling by choosing one element from the social foundation and one from the ecological ceiling and considering how they might be connected. Some connections might be relatively easy to link, like air pollution and health. Others are more challenging.


If you want to avoid very challenging connections, you may wish to focus on:

Try this out alone, or in pairs, sharing your ideas with the larger class or your teacher.

You can also create a physical Doughnut Spinner, a small version for individual use, or a large classroom version to continue exploring connections between the social foundation and ecological ceiling. The Doughnut Economics Action Lab has instructions.

Option 2 - Comparing countries on the Doughnut

30 minutes


The website  A Good Life For All Within Planetary Boundaries has abundant data on the status of countries’ social foundation and ecological overshoot.
