Example text
The strikes brought to their minds another set of images, associated with the working classes and underclasses of European cities. The secretary of state for the colonies hoped to redefine the problem. He used the anxiety within the government to argue for making a gesture, which he saw as opening the door to a more vigorous colonial policy. The central concept he invoked was ‘development’, a word sometimes used to describe investment in the colonies intended to produce a return to British interests, but now linked to the word ‘welfare’.
32 As in France, thinking within the administration was compartmentalized: the experts in economic planning ignored the evidence of increased cocoa production from smallholders in Nigeria and the smallscale coffee production of Tanganyika. 33 Prejudices of this sort had serious consequences on the ground: programmes to promote soil conservation among supposedly ignorant cultivators in Kenya, Tanganyika and Rhodesia, brutally implemented by British agronomists, led to rebellions in these areas. Here we have a central problem in colonial-style developmentalism.
Administrations needed expert advice. They could call on agronomists or public-health specialists with some experience in the tropics, and for social engineers they had to turn to people like labour inspectors who had practical experience in Europe. Among economists, it took time for the profession to develop the expertise to engage in planning. Still, theoretical innovations beginning in the early 1950s would come to have great influence on framing knowledge of change in Africa. I will emphasize two: a branch of modernization theory that focused on industrialization as the key arena of transformation and development economics.
