An aerial view shows pools of mineral-coloured water gathered on salt flats in holes dug by salt collectors on the Senegalese coastline near the border with Gambia June 12, 2006. Women collect salt by hand into 50kg (110lbs) sacks, which sell for about $2, and are traded with neighbouring Gambia and Mauritania, where salt is mainly used for preserving fish in areas without electricity.
