From field to future: The evolution of agricultural extension in the digital age for sustainable and revitalized rural economies

Abstract

Agricultural extension has long been the bridge connecting scientific research with farming practice. Traditionally, extension agents traveled to villages to demonstrate new techniques and train farmers, working to increase productivity and improve livelihoods. Today, however, the field of extension is rapidly evolving. Digital technologies including mobile phones, satellites, data analytics and artificial intelligence are transforming how farmers receive advice and support. This article traces the history of agricultural extension and examines its modern transformation in the “digital age.” We discuss how innovations in communication and information technology have expanded the reach and speed of extension services worldwide. The discussion highlights both global and Indian experiences, noting key milestones, pioneering figures and innovative programs. We also consider the impact of digital extension on sustainable rural economies, including increased yields, income growth and environmental benefits. Finally, we address challenges (like the digital divide and content relevance) and outline future directions to fully realize the potential of digital extension for sustainable rural development.
