This paper takes up the problem of how to structure a productive and genuin
e interdisciplinary engagement from the standpoint of geography. It examine
s first what makes interdisciplinarity difficult, focusing on the productio
n of disciplinary cultures that define the material practices, social relat
ions and epistemological commitments characteristic of a field of study. Th
e paper then considers why interdisciplinarity seems to be in the ascendant
and why and how geography has been used in this project. It cautions again
st a reductionist or imperialist style of interdisciplinary work and encour
ages geographers to develop their own approach to a productive engagement w
ith other fields, in part through attending to the interdisciplinarity inhe
rent in our own.
