Hi Glenn,
I apologize for the delayed response. I am not affiliated with NCAT (National Center for Appropriate Technology) so I can only speak on what I learned from their sight. I believe ECHO and NCAT both strive to reduce global food insecurity, and NCAT has several field offices in the US. Here is a link to NCAT’s home page (LINK HERE), NCAT houses several focus specific programs like ATTRA (Appropriate Technology Transfer for Rural Areas). It is this program that conducted the study I noted above.
