As head of the University of Hawaii’s extension services, F. G. Krauss played a pivotal role in teaching sustainable farming practices during the war. He traveled across the islands offering demonstrations on composting, crop rotation, and pest control—all aimed at maximizing productivity for both backyard gardens and small farms. Krauss also helped coordinate food surveys that guided policy for the Territorial Food Commission. His work ensured that Hawaii’s farming community could continue to function despite labor shortages and global supply disruptions.
