For the first half of the twentieth century,
physical geography informed regional geo-
graphic enquiry. At its most obvious, physical
geography provided a natural definition of
regions where economic and social activity
appeared adjusted to, or bounded by, the nat-
ural environment. Away from the obvious
physio-climatic regions, where physical geog-
raphy was merely a convenient backdrop, the
degree and manner in which physical geog-
raphy truly engaged the human landscape
was a vexing issue. Failure to answer this sat-
isfactorily legitimized a fundamental dualism
of geography, which was never successfully
reconciled. Environmental determinism ran
its course rather quickly, and human ecology
(Barrows, 1923) became not merely its suc-
cessor, but one of the defining and prescriptive
terms for geography itself (Turner, 2002).
While the concern was still to find something
new and unique to define the subject, there
was a critical twist for physical geography,
insofar as:
I believe that the age-old subject of geog-
raphy, though it has lost many specialities,
still seeks to cover too much ground, and
that it would benefit by frankly relinquish-
ing physiography, climatology, plant ecol-
ogy, and animal ecology. (Barrows, 1923,
p. 13)
In this way, geography was not only reorien-
tated but, with it, physical geography was
cancelled from the geographical project (for
an accessible treatment of these issues, see
Unwin, 1992). Physical geography was
increasingly identified as a particular form of
geographical activity (most frequently mani-
fest as applied geography) rather than as a
coherent intellectual field, and at best, referred
to obliquely when considering the role of
human–environment relations within geog-
raphy as a whole.
Not all were happy with a separation of
human and physical geography, of course,
and displeasure or unease came from many
quarters. Hartshorne (1939), for example,
was at pains to draw attention to the effective
elimination of physical geography, and thereby
to the restriction of geography. This was not
advocacy of physical geography for its own
sake, but an appeal to the heritage of
Humbolt and others, which held that nature
was essentially unitary. Geography’s mission
was to disclose areal association, andsystematic
studytook precedence over any particularsub-
ject matter. Dualism had arisen because of
philosophical abstraction and a concern to
study categories of phenomena in isolation
(Hartshorne, 1959). Much the same senti-
ments were expressed by physical geographers
such as Miller or Wooldridge, who maintained
a belief in the foundational role of physical
geography for regional study, even where con-
nections were subtle or unclear:
... to hurry on content with a few shallow
remarks based on perfunctory observation
of the physical elements of the environment
may result in overlooking or falsifying the
natural intimacy of relation that nearly al-
ways exists between the physical and the
cultural landscape. (Miller, 1953, p. 196)
Such convictions, although deeply situated,
were rarely compellingly demonstrated, and
the prevailing view of geography was one of
numerous separate branches, united only in
the far distant past (figure 2). Moreover, the
very appeals to unity based upon identification
or prescription of some essential property of
geographical analysis may have contributed to
the overshadowing of physical geography,
both within geography and in relation to the
other environmental sciences (Leighly, 1955).
Leighly argued, very simply, that geographical
study ofanyEarth surface phenomenon could
be justified not for its own sake (as often mis-
represented) butbecauseits existenceinplace
gave it legitimacy as the subject of geograph-
ical enquiry. By contrast, a physical geography
