This paper concerns the changing climate in the semiarid regions of Africa and the technological response to it. Often the central issue in physical and social change in Africa seems to be interpreting a sketchy but rapidly evolving base of "evidence" and trying to decide the process that the evidence would suggest is at work. This is a far from easy task, requiring inspired guesswork as much as proof, but clearly it is absolutely central to formulating an appropriate policy response.
