ECHO Development Notes (EDN)

At the center of our work is ECHO Development Notes (EDN), which we send quarterly to thousands of people in over 160 countries in three languages (English, French, and Spanish). In EDN we share the most helpful, practical information that we come across about growing food under difficult circumstances. 

Within each issue you'll find featured techniques, practices, information and experience to help guide your work in tropical and subtropical agricultural development. Also in EDN are "Echoes from Our Network," "From ECHO's Seed Bank," and more. Issues #1-51 were compiled in the 1990s into the Amaranth to Zai Holes book, which  or you may read it online here. Also, Agricultural Options for Small Scale Farmers, expanded on the foundation from Amaranth to Zai Holes by covering EDN 52 through 100, with articles from outside contributors. Agricultural Options for Small Scale Farmers is available for purchase from the ECHO Bookstore and Amazon.

EDN Issue #166 - 2024-10-01

ECHO is excited to share with you that we are re-engaging with our Central America and Caribbean (CAC) partners and network members through the establishment of a Regional Impact Center (RIC). We have heard the needs in the region and are focusing our efforts on being able to fully support a RIC located in CAC. This RIC will be dedicated to developing contextualized sustainable options for smallholders. This issue of EDN features a technique, a CAC partner system, and a crop relevant specifically to the CAC region and with global potential as well!
