Agricultural extension is also known as agricultural advisory services.  In simple terms, it means giving farmers, especially smallholders in developing countries – knowledge of agronomic techniques and skills to improve their productivity, food security and livelihoods.  The Ag Extension Online was initially developed by Dr. Mark Bell when he was the Director of the International Ag Extension and Asst Director for the then International Programs Office, CA&ES, UC Davis (https://ucanr.edu/sites/anrstaff/Divisionwide_Programs/Program_Council/?facultyid=33294) .  This online resource was created for extensionists, farmers and other experts around the world to provide tools and best practices to improve their extension services.  For more information, please visit:  http://AgExtOnline.com.
