This handbook is written so that participating farmers and their families can equitably address food production and nutrition issues for good health. FFS participants are encouraged to share what they learn with farmers in their community, schools and other community groups so their whole community benefits. Persons working in extension support services such as Agricultural Extension Development Officers (AEDOs), Health Surveillance Assistants (HSAs), and other service areas (Community Development, Forestry, Environmental Health, Teacher Development Centres, schools, etc.) can use the handbook to support farming families to diversify food production and utilization for better nutrition.
