Agricultural extension is the application of scientific research and new knowledge to agricultural practices through farmer education. The field of 'extension' now encompasses a wider range of communication and learning activities organized for rural people by educators from different disciplines, including agriculture, agricultural marketing, health, and business studies. Extension practitioners can be found throughout the world, usually working for government agencies. They are represented by several professional organizations, networks and extension journals.
The use of the word 'extension' originated in england in 1866.Modern extension began in Dublin, Ireland in 1847 with Lord Clarendon's itinerant instructors during the great famine.[1] It expanded in Germany in the 1850s, through the itinerant agricultural teachers Wanderlehrer and later in the USA via the cooperative extension system authorized by the Smith-Lever Act in 1914. The term was later adopted in the United States of America, while in Britain it was replaced with "advisory service" in the 20th century.
There is some disagreement about whether or not the concept and name of 'extension' really encompasses all four paradigms. Some experts believe that the term should be restricted to persuasive approaches, while others believe it should only be used for educational activities. Paulo Freire has argued that the terms ‘extension’ and ‘participation’ are contradictory.[12] There are philosophical reasons behind these disagreements. From a practical point of view, however, communication processes that conform to each of these four paradigms are currently being organized under the name of extension in one part of the world or another. Pragmatically, if not ideologically, all of these activities are considered to be represented in agricultural extension.
