Geography, like all other academic disciplines, is fragmented into a l
arge number of specialist communities, within which research occurs an
d individual careers are structured: Geography is characterized by at
least four cleavages. Such fragmentation is necessary to scientific pr
ogress, but threatens the discipline's status and funding within acade
mia, hence the attempts to defend Geography's territory within the aca
demic division of labour. Geography's situation may be more acute than
that for many other disciplines, because of its multifarious external
links.
