Nothing illustrates the economic and social diversity better than farming methods. Whilst tractors are used in some areas, the indigenous people on their small farms still work the fields in a way that has not changed since the time of the Incas. - This image shows the breaking up of the soil with the taclla, an agricultural tool originating in the Peruvian Andes. It is essentially a long-handled spade that the Incas have used since ancient times. Its shape allows it to be pushed with the foot into hard ground. - Book: Picture 90 - Peru - 1976
