Based the IEEE Internet of Things (IoT) Initiative, this book presents results from the focused discussions of experts, academic professors, government officials, and practitioners on the subject of the digital future of agriculture. The book has four sections which respectively address its background and motivation, what IoT is all about, the importance of the large and varied agriculture sector, and use cases in a subset of agriculture sub-sectors and for common functions. In all, this book is written for a general but knowledgeable audience, and is intended as a high level yet practical overview of how IoT is likely to impact agriculture, why it is important, and to provide illustrative examples that describe the basic concepts at work.
