The document summarizes KTDA's sustainable agriculture project which uses Farmers Field Schools (FFS) and Rainforest Alliance (RA) certification to promote sustainable farming practices. The project has trained over 300 TESAs as facilitators and established over 500 FFS across 55 factories. Key achievements include increased yields, farmer empowerment, and continued production of high quality tea. However, challenges remain around capacity, education levels, competition, and costs of compliance. The project aims to scale up FFS to reach all smallholder farmers by 2015.
