GCCF conducted field studies to estimate on-farm losses for various types of products, farm sizes and geographies. Products included potatoes, tomatoes, and leafy greens as well as fruit trees (specifically peaches). GCCF also supported WWF in conducting commodity systems and training needs assessments, business association development, and facilitate regional cold chain exposure and participation, providing a final report that encompassed on-farm and postharvest loss reports summarizing losses experienced at each of the major stages from farm to postharvest stage for each commodity.
