Adding measures such as jobs, education, food, access to water, health services and energy helps to accommodate an environmentally safe space compatible with poverty eradication and 'rights for all'. She suggested social boundaries should be combined with the planetary boundaries structure. Kate Raworth noted the planetary boundaries concept does not take human wellbeing into account (although, if Earth's ecosystem dies then all wellbeing is moot). This situation is represented by the area between the two rings, considered by its creator as a safe and just space for humanity. In this model, an economy is considered prosperous when all twelve social foundations are met without overshooting any of the nine ecological ceilings. In this context, the model is also referred to as a 'wake-up call to transform our capitalist worldview'. The main goal of the new model is to re-frame economic problems and set new goals. The framework was proposed to regard the performance of an economy by the extent to which the needs of people are met without overshooting Earth's ecological ceiling. The diagram was developed by University of Oxford economist Kate Raworth in her 2012 Oxfam paper A Safe and Just Space for Humanity and elaborated upon in her 2017 book Doughnut Economics: Seven Ways to Think Like a 21st-Century Economist and paper. The centre hole of the model depicts the proportion of people that lack access to life's essentials ( healthcare, education, equity and so on) while the crust represents the ecological ceilings ( planetary boundaries) that life depends on and must not be overshot. The name derives from the shape of the diagram, i.e. The Doughnut, or Doughnut economics, is a visual framework for sustainable development – shaped like a doughnut or lifebelt – combining the concept of planetary boundaries with the complementary concept of social boundaries. The classic image of the Doughnut the extent to which boundaries are transgressed and social foundations are met are not visible on this diagram
