Crops or Crafts? Changes in Land Use in the Imbabura Valley of Ecuador
… three data collection techniques were employed: repeat photography, ethnographic interviews, and archival research. Repeat photography involves re-photographing historic photographs from the original site. A combination of 35 historic photographs taken in the 1950s were re-photographed during the …
