ECHO has been sending out ECHO Development Notes since the first issue in 1981! 2021 marked the 40th anniversary of ECHO as well as this important publication that Dr. Price started writing to share information he was learning with active development workers around the world. Issues of EDN were originally mailed out to people all over the world but are now shared via email and hosted on ECHOcommunity.org. Starting with EDN 47, issues were translated into Spanish! Issue 91 marked the beginning of the French translation for EDN. Although EDN has looked different across the years, it still functions as a means for sharing relevant, accessible agricultural information with ECHO's network of practitioners around the world. This quarterly technical publication provides credible research, experiences from around the world, and low-tech options that address smallholder agricultural needs.
