The document discusses common interest youth groups and their contribution to food security in Western Kenya. It finds that youth, especially married and more literate youth, joined these groups through change agents and promotional posters. Being in a group provided members access to farm inputs and training, allowing some to increase production levels. While groups faced constraints like lack of finances, they helped members achieve higher levels of food security compared to non-members, as measured by indicators and coping strategies. The document concludes that continuing to form these groups and providing them support can further enhance household food security in the region.
