Repeat Photography

rePhotoSA

rePhotoSA is the repeat photography project of southern African landscapes and is a collaborative project between the Plant Conservation Unit (PCU) and the Animal Demography Unit (ADU) at the University of Cape Town. 

rePhotoSA engages with the public as ‘citizen scientists’ to repeat modern photographs of southern African landscapes, from a large collection of historical photographs. By comparing the differences in the ‘old and new’ photographs it is possible to gain an understanding of how southern African landscapes are changing in response to climate, land use and development impacts (see examples below).

There are several ways in which you can contribute to the success of rePhotoSA. This includes the opportunity to Become a citizen scientist, to Donate historical photographs of landscapes and to Become a donor of funds towards running costs of the project. Visit the rePhotoSA website to Search photos of historical landscapes of southern Africa and to find out more on how to Get involved in this innovative project.
