Guests and ideas explored on this week's BBC discussion programme The Forum: http://www.bbc.co.uk/programmes/p0065nmq

Sarah Hough

After the devastation of the earthquake in Haiti, which city or country might be next? The bad news: predicting catastrophes like this is still beyond the means of modern science according to American earthquake authority Susan Hough. She tells The Forum about what triggers earthquakes and the latest research into warning signs.

David Adjaye

British Ghanaian architect David Adjaye describes the unique quality of many African cities, founded at the heart of African empires rather than on trade and industry. He looks at ways of challenging the boundaries between inside and outside, bringing nature closer to our homes.

Sara Wheeler

Polar explorer Sara Wheeler was the first female writer in residence in the Antarctic. She contrasts this polar extreme with her journeys around the northern wastes of the Arctic Circle which she sees as the perfect metaphor for middle age.
