Richer countries import many health workers from poorer countries, whilst at the same time exporting their ideas and ideologies about health. It is an unfair exchange. What would it be like if it were the other way round – and poorer countries imported health workers from richer ones and exported their ideas and experience about health?

Published earlier this year, Turning the World Upside Downexplores what richer countries can learn from poorer ones and suggests that, instead of talking of international development – where the richer help the poorer – we should think in terms of co-development, each learning from the other. By bringing together insights from all parts of the world, the book sets out a new vision for global health, based on our interdependence, our desire for independence and on our rights and accountabilities as citizens of the world.

Author, Nigel Crisp, gave a keynote lecture unpacking some of the ideas in his book and drew upon his vast experience from working in the developing world, as Chief Executive of the NHS and Permanent Secretary to the UK Department of Health.
