The Conceptualization Of “Environmentalism” In Sagara, Emma Chapman
Independent Study Project (ISP) Collection
My study focused on the perceptions of “environmentalism” in Sagara, Tanzania and attempted to compare Sagaran concepts to those of a more Western model. My study also identified the “actors” that taught Sagarans about the environment. After finding that Sagarans held a strong resource conservation focus in their responses, I then focused on the details of their resource use to see whether what they have been taught about conservation has been actualized in their daily life. I predicted to find that Sagarans have a much more generalized and resource conservation focused definition of “environmentalism” and that their patterns of resource …
