James F. Evans Collection; See C06647 for original; Based on a thesis submitted to the University of Pretoria in partial fulfillment of the requirements for the degree M. Inst. Agrar., This study examines the influence of tribal leaders and front line extension workers on agricultural development in Swaziland. Based on a 12 percent stratified random sample including 23 chiefdomss, 46 tribal leaders and 23 front line extension workers were interviewed by using a structured interview schedule. In search of a valid measure of agricultural development, several indicators were used. The number of cattle per homestead, the saving status of homesteads and the subjective ratings by senior extension personnel were found to be invalid. Evaluated against an agricultural development index it was found that tribal leaders, although not as important as extension workers, were found to have a significant influence, especially as far as their involvement, inputs, credibility and their perceptions are concerned. These findings suggest that tribal leaders, if involved in a positive way, can contribute towards agricultural development, although more research is needed concerning, inter alia, valid criteria for measuring agricultural development and the analysis of the perceptions of subordinates (original).
