ASPECTS OF ECONOMIC HISTORY
were probably eating a little better, yet food imports were still
small and consisted almost entirely of luxury and semi-luxury
items consumed by the immigrant communities and a few of the
most prosperous Africans. Nor would it be correct to say that
Africa had been de-industrialised in order to make way for the
export-import economy. The smelting of iron ores, formerly a
widespread activity, had indeed practically ceased, and blacksmiths
had been reduced to the reforging of scrap metal. On the other
hand, where cotton textile-production was well-established (that
is,
mainly in West Africa) it had maintained its position, since the
factory-made imports, though cheaper than the traditional
product, were on the whole less desirable. And losses in some of
the old crafts were at least offset by the rise of new ones, such
as vehicle maintenance, bicycle repair and tailoring (with the now
ubiquitous treadle sewing-machine), as well as the various
'modern' building trades.
At the same time, the application of land and labour to export
production was far from being a cost-free process. It is true that
land continued to seem abundant except in a few special areas,
notably in south-east Nigeria, parts of Kenya, Basutoland and the
native reserve areas of South Africa. But in a good many other
areas the extension of cultivation, brought about by the combina-
tion of the export demand and the growth of population, began
to disturb the often precarious ecological balance. Bush fallows
were shortened and the depleted soils became more vulnerable to
erosion. The removal of forest and woodland cover also promoted
both erosion and leaching of the soil, and may have altered local
climates for the worse. The alarms raised by ecologists in the
inter-war period, which led to the appearance of books with titles
like 'Africa, the dying land', seem with hindsight to have been
excessive or at any rate premature;

but it cannot be doubted that
agricultural activity was already causing some loss of natural
capital. By comparison the effects of mining were less serious, for
although minerals are more obviously a non-renewable resource
than surface soils the operations in our period had hardly even
begun to exhaust the reserves of any of the principal ores.
The salient feature of the colonial era for Africans was

put an end to organised life in the United States by the end of the century and in Africa
almost certainly before that.
