Extension and Advisory Services - Terminology and Glossary

Agricultural Extension was once known as the application of scientific research, knowledge, and technologies to improve agricultural practices through farmer education. The field of extension now encompasses a wider range of communication and learning theories and activities (organized for the benefit of rural people) by professionals from different disciplines. There is no generally accepted definition of agricultural extension, but the one provided above is widely used and is the one promoted by the Global Forum for Rural Advisory Services, GFRAS. There are different schools of thought about how agricultural extension systems should be organized and function.
 
Agricultural extension uses a number of different terms to describe specific concepts and approaches, a selection of which are described in this glossary.
