The use of indigenous knowledge has been seen by many as an alternative way of promoting development in poor rural communities in many parts of the world.

These include problems emanating from a focus on the (arte)factual; binary tensions between western science and indigenous knowledge systems; the problem of differentiation and power relations; the romanticization of indigenous knowledge; and the all too frequent decontextualization of indigenous knowledge.
