Abstract

In many developing countries people and livestock suffer from preventable or curable diseases, and their agriculture is vulnerable to natural disasters. A considerable amount of technical aid is directed at alleviating these problems using modern science and technology, and yet most of these efforts either fail or even leave peasants and pastoralists worse off than before. In this paper we consider some of the problems that arise in relation to development projects, focusing our attention on the savannah regions of Africa and, in particular, on the control of tsetse flies, which are the vectors of the African trypanosomiases, called nagana in cattle and sleeping sickness in people. We present a detailed case study of a project designed to enable a Maasai community in Kenya to carry out their own tsetse fly control. We examine the complex set of relationships and power structures that mediate the actions of the players in development: scientists, local communities, governmental and nongovernmental institutions, and development agencies. The purpose of this paper is not to present solutions to complex and difficult problems but rather to raise questions that should provide a framework for a debate concerning the role of science and technology in the development process
