In a small village near Tamale in northern Ghana, a group of men and women sit around in a semi-circle, discussing the chart they've drawn in the dust. The chart has three columns, showing the hours in the day, and the different tasks men and women undertake during those hours. It soon becomes clear that it's the women who undertake the most labour intensive work - fetching water and firewood, cleaning and preparing food - and the discovery sparks a lively debate about why the men can't take on more 'women's' work.
