Preface The On-Farm Grain Storage Project is pleased to make this exten- sion communication manual available to Kenya's Ministry of Agri- culture. It is hoped that this practical guide will serve Kenya's front-line agricultural extension staff for many years. The front-line workers are general agriculturalists and they must deliver information to farmers on a wide range of subjects. Their effectiveness in this task depends both on their knowledge of their subjects and on their ability to communicate with farmers. The author speaks directly to the front-line workers. And the suggested methods and techniques should have application in the communication of subjects across the full range of agricultural extension-not just post-harvest management. Likewise, the infor- mation contained in the manual should be of use to those educa- tional institutions which train Kenya's agricultural extension staff. Also, the manual will have relevance for extension staff in other countries. The author, John Fox, has nearly thirty years experience in adult education and extension communication. He has taught communi- cation skills, conducted research programmes, produced simula- tions and games, video training tapes and previous handbooks on communication. He has over ten years of work experience with various professional groups in Kenya and other African countries. He spent two years teaching communication and adult education skills at the University of Nairobi's Adult Studies Centre, Kikuyu. In preparation for this manual, John Fox accompanied front-line extension workers on their daily farm visits to gain close, first hand experience of their work routines and interactions with farmers- and he has attended numerous project field days in western Kenya. The chapters follow a logical pattern. The first five explore the case for employing a discussion and action-based methodology in exten- sion work; the following chapters show how this methodology can be applied in a variety of situations and formats. The agricultural extension workers who read this manual will find guidelines and checklists for individual application. But the man- ual also contains material that can be adapted for role playing and discussions in training groups. Dr. Walter G. Heid, Jr Team Leader, DPRA On-Farm Grain Storage Project
