This book is the results of research done in East Usambara Mountains in Tanzania specifically in Muheza District. The purpose of this study was to investigate the role played by adult education in sensitizing the adult population on biodiversity conservation. Specifically, the study intended to explore the role of adult education in awareness creation on biodiversity conservation, measures taken to achieve biodiversity conservation and appropriateness of the methods used to educate the adult population on biodiversity conservation. This is a good book for adult education practitioners as it gives experience on the field of biodiversity conservations for adults. This book can help environmental educators to use appropriate methods and approaches in teaching adults, also can help biodiversity conservers should to cooperate and design relevant adult education curriculum that accommodates biodiversity education. I recommend experts on environmental conservation and adult educators to use this experience in improving andragogy in order to prevent biodiversity extinction.
