Agricultural Extension and Education in the 21\(^{st}\) Century

International audience Agriculture remains the backbone of many economies, particularly in developing nations, where it directly supports livelihoods, food security, and rural development. As the sector continues to evolve under the influence of globalisation, technological advancement, climate change, and policy reforms, the role of agricultural education and extension has become more critical than ever. These two disciplines are not merely academic pursuits but are practical pillars that bridge the gap between research, innovation, and the farming communities that sustain nations.This book provides a comprehensive and timely exploration of the concepts, philosophies, methods, and evolving trends that define agricultural education and extension today. From tracing their historical foundations to examining modern digital approaches, it offers learners, practitioners, and policymakers a well-rounded resource that emphasises both theory and practice. The inclusion of practical examples, contemporary challenges, and strategies for the future makes this work highly relevant in addressing real-world agricultural needs.One of the most valuable contributions of this text is its focus on contextualising global knowledge to the African and Kenyan experience, while also drawing comparative insights that resonate universally. By highlighting participatory approaches, e-extension tools, and the integration of sustainability, the book underscores the importance of inclusive, adaptive, and forward-looking systems of agricultural knowledge transfer.For students, this book will serve as a foundational guide. For extension workers and development practitioners, it will be a practical reference to inform their day-to-day work. For policymakers and researchers, it provides insights into the role of education and extension in achieving food security, poverty reduction, and the Sustainable Development Goals.It is my sincere hope that this book inspires its readers to appreciate the transformative power of agricultural education and extension in shaping resilient farming communities and sustainable rural economies. Indeed, the future of agriculture lies not only in new technologies but also in the effective dissemination of knowledge and the empowerment of people.
