Great to hear you are interested in learning about the issues that farmers face. Reaching out to agricultural faculty at the Universities would be great way to have a detailed discussion! I have learned a lot from extension agents and teaching/research faculty (both 'old timers', and the new ones!). A lot of the issues that affect farming are similar issues that affect conservation work in the Islands. For examples, the water / irrigation issues are amazingly complex regarding agriculture and more natural ecological systems.
