INTRODUCTION
wage-earners, wartime price inflation reduced already meagre real
incomes by as much as one
half.
The damage done by the war
rendered Africans highly vulnerable to the influenza pandemic of
1918-19: perhaps
2
per cent succumbed. Climatic change was
probably yet another burden upon Africa; for there is reason to
suppose that the present century has been unusually dry. This has
mattered most
in
the semi-arid lands fringing the Sahara, but
severe drought struck much of eastern and southern Africa in the
early 1930s.
In
southern Africa,
the
ruthlessness with which
labour continued
to
be mobilised damaged African health on
a
scale which
far
outweighed any local amelioration by western
medicine. By the 1930s tuberculosis was rife in rural South Africa
among returned mine-workers, while railway-building and work
on sugar-plantations
had
spread malaria through Natal
and
Zululand. In tropical Africa, however, colonial regimes were by
the end of our period on balance a positive rather than negative
influence on population. For many people, the growth of trade
meant somewhat better food and clothing, while the growth of
government and motor transport made possible famine relief and
rural medical services. The life-chances
of
Africans were not
particularly good, but
in
many areas they were beginning
to
improve. In retrospect, one may discern in much of Africa
a
period
of relative calm and rising hopes between the violence
of
the
earlier twentieth century and the wars which have been either
cause or consequence of decolonisation.
Movements of people were as much a feature of this period as
of any earlier phase
in
Africa's past. Most moved
to
work for
wages, in mines, plantations and towns. In 1910 about 2.5 million
peopie in Africa were living in cities whose population exceeded
100,000; this number had roughly doubled by 1936, when 2.1m
were in Egypt, 1.4m elsewhere in North Africa, and 1.3 m in South
Africa (where one in six Africans were living in
towns).
In tropical
Africa, large towns were still exceptional: the biggest were Ibadan
(318,000) and Lagos (167,000). But old seaports took on new life
and new ports were developed, while in the far interior new towns
grew from next to nothing.
In
1936 there were populations of
between 50,000 and 100,000
in
Dakar, Luanda and Lourenco
Marques (Maputo), and also in Nairobi, Salisbury (Harare) and
Elisabethville (Lubumbashi). Many urban dwellers were short-
stay migrants, like most workers on mines or plantations; it was
