Development schemes are common throughout the third world. Many fail, but the reasons for failure or success are only too often not adequately studied. In this monograph two schemes started in Basutoland - now Lesotho - are intensively analysed and compared: the first, which was abandoned in 1961, primarily by means of documentary material, the second, which was and still is successful in at least part of the area, mainly through observation and field research. The analysis reveals the factors making for success or failure, particularly in the fields of politics, economics, and communication. The relevance of the study extends beyond Lesotho and even Africa, the analysis dealing with problems common to introduced social change and development in any part of the world.
