Conrad Feather, a student from Cambridge University, lived several years with the Nahua people of Peru in the Amazon, helping them drive illegal loggers from their land. Recently he trained them to use GPS devices so that they could create the first map of their territory and make an ambitious bid to win legal title to it.

They spent over a year collecting information and putting it into a computer to create a cultural map illustrating where they go hunting and fishing, where they collect important plants and fruit, where they have had villages in the past and where people have died and are buried. It contains almost everything that is important to them.

His project won him the St Andrews Prize for the Environment
