This week, we take a bird's-eye-view of the sustainable ag movement and the research initiatives that sustained it's beginnings. 

Ferd Hoefner is a Senior Strategic Advisor for the National Sustainable Agriculture Coalition, (N-SAC). He has worked on national food and agriculture policy in Washington, DC for forty years. He helped create  the USDA-program that we now know as SARE, and has seen it grow and develop throughout the years.

Andy Clark is National Communications Director for SARE, and began his involvement with sustainable ag in the late-1980s. When he was in graduate school, he received a research grant from LISA, the program precursor to SARE, for cover cropping no-till corn. Now, he's responsible for sharing the results of SARE grants and research with farmers and educators around the country.
